their ability to perform dangerous and time-consuming tasks on the water. Object detection tasks are significant in these applications. However, inherent challenges, such as the complex distribution of obstacles, reflections from shore structures, water surface fog, etc., hinder the performance of object detection of USVs. To address these problems, this paper provides a fusion method for USVs to effectively detect objects in the inland surface environment, utilizing vision sensors and 3+1D Millimeter-wave radar. MMW radar is complementary to vision sensors, providing robust environmental information. The radar 3D point cloud is transferred to 2D radar pseudo image to unify radar and vision information format by utilizing the point transformer. We propose a multi-source object detection network (RV-YOLOX )based on radar-vision fusion for inland waterways environment. The performance is evaluated on our self-recording waterways dataset. Compared with the YOLOX network, our fusion network significantly improves detection accuracy, especially for objects with bad light conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inland%20waterways" title="inland waterways">inland waterways</a>, <a href="https://publications.waset.org/abstracts/search?q=YOLO" title=" YOLO"> YOLO</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor%20fusion" title=" sensor fusion"> sensor fusion</a>, <a href="https://publications.waset.org/abstracts/search?q=self-attention" title=" self-attention"> self-attention</a> </p> <a href="https://publications.waset.org/abstracts/164399/rv-yolox-object-detection-on-inland-waterways-based-on-optimized-yolox-through-fusion-of-vision-and-31d-millimeter-wave-radar" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164399.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">124</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">108</span> Polymer-Ceramic Composite Film Fabrication and Characterization for Harsh Environment Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santiranjan%20Shannigrahi">Santiranjan Shannigrahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohit%20Sharma"> Mohit Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivan%20Tan%20Chee%20Kiang"> Ivan Tan Chee Kiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Anna%20Marie"> Yong Anna Marie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polymer-ceramics composites are gaining importance due to their high specific strength, corrosion resistance, and high mechanical properties, as well as low cost. As a result, polymer composites are suitable for various industrial applications, like automobiles, aerospace, and biomedical areas. The present work comprises the development of polymer-ceramic composite films and is tested for the harsh environment including weatherability and UV barrier property. The polymer composite films are kept in weather chamber for a fixed period of time followed by tested for their physical, mechanical and chemical properties. The composite films are fabricated using compounding followed by hot pressing. UV-visible spectroscopy results reveal that the pure polymer polyethylene (PE) films are transparent in the visible range and do not absorb UV. However, polymer ceramic composite films start absorbing UV completely even at very low filler loading amount of 5 wt.%. The changes in tensile properties of the various composite films before and after UV illuminations for 40 hrs at 60 degC are analyzed. The tensile strength of neat PE film has been observed 8% reduction, whereas the remarkable increase in tensile strength has been observed (18% improvement for 10 wt. % filled composites films). The UV exposure leads to strengthen the crosslinking among PE polymer chains in the filled composite films, which contributes towards the incremented tensile strength properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polymer%20ceramic%20composite" title="polymer ceramic composite">polymer ceramic composite</a>, <a href="https://publications.waset.org/abstracts/search?q=processing" title=" processing"> processing</a>, <a href="https://publications.waset.org/abstracts/search?q=harsh%20environment" title=" harsh environment"> harsh environment</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a> </p> <a href="https://publications.waset.org/abstracts/34302/polymer-ceramic-composite-film-fabrication-and-characterization-for-harsh-environment-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34302.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">383</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">107</span> Formulation of a Stress Management Program for Human Error Prevention in Nuclear Power Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyeon-Kyo%20Lim">Hyeon-Kyo Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Tong-il%20Jang"> Tong-il Jang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Hee%20Lee"> Yong-Hee Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As for any nuclear power plant, human error is one of the most dreaded factors that may result in unexpected accidents. Thus, for accident prevention, it is quite indispensable to analyze and to manage the influence of any factor which may raise the possibility of human errors. Among lots factors, stress has been reported to have significant influence on human performance. Stress level of a person may fluctuate over time. To handle the possibility over time, robust stress management program is required, especially in nuclear power plants. Therefore, to overcome the possibility of human errors, this study aimed to develop a stress management program as a part of Fitness-for-Duty (FFD) Program for the workers in nuclear power plants. The meaning of FFD might be somewhat different by research objectives, appropriate definition of FFD was accomplished in this study with special reference to human error prevention, and diverse stress factors were elicited for management of human error susceptibility. In addition, with consideration of conventional FFD management programs, appropriate tests and interventions were introduced over the whole employment cycle including selection and screening of workers, job allocation, job rotation, and disemployment as well as Employee-Assistance-Program (EAP). The results showed that most tools mainly concentrated their weights on common organizational factors such as Demands, Supports, and Relationships in sequence, which were referred as major stress factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20error" title="human error">human error</a>, <a href="https://publications.waset.org/abstracts/search?q=accident%20prevention" title=" accident prevention"> accident prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20performance" title=" work performance"> work performance</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue" title=" fatigue"> fatigue</a> </p> <a href="https://publications.waset.org/abstracts/47927/formulation-of-a-stress-management-program-for-human-error-prevention-in-nuclear-power-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47927.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">326</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">106</span> Design of an Eddy Current Brake System for the Use of Roller Coasters Based on a Human Factors Engineering Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adam%20L.%20Yanagihara">Adam L.

It was necessary to find what could be deemed as a “comfortable” deceleration so that passengers do not feel as if they are suddenly jerked and pressed against the restraining harnesses. A human factors engineering approach was taken in order to determine this deceleration. Using a previous study that tested the deceleration of transit vehicles, it was found that a -0.45 G deceleration would be used as a design requirement to build this system around. An adjustable linear eddy current brake using permanent magnets would be the ideal system to use in order to meet this design requirement. Anthropometric data were then used to determine a realistic weight and length of the roller coaster that the brake was being designed for. The weight and length data were then factored into magnetic brake force equations. These equations were used to determine how the brake system and the brake run layout would be designed. A final design for the brake was determined and it was found that a total of 12 brakes would be needed with a maximum braking distance of 53.6 m in order to stop a roller coaster travelling at its top speed and loaded to maximum capacity. This design is derived from theoretical calculations, but is within the realm of feasibility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eddy%20current%20brake" title="eddy current brake">eddy current brake</a>, <a href="https://publications.waset.org/abstracts/search?q=engineering%20design" title=" engineering design"> engineering design</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20synthesis" title=" design synthesis"> design synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20factors%20engineering" title=" human factors engineering"> human factors engineering</a> </p> <a href="https://publications.waset.org/abstracts/123650/design-of-an-eddy-current-brake-system-for-the-use-of-roller-coasters-based-on-a-human-factors-engineering-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123650.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">105</span> The Effect of Different Concentrations of Extracting Solvent on the Polyphenolic Content and Antioxidant Activity of Gynura procumbens Leaves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kam%20Wen%20Hang">Kam Wen Hang</a>, <a href="https://publications.waset.org/abstracts/search?q=Tan%20Kee%20Teng"> Tan Kee Teng</a>, <a href="https://publications.waset.org/abstracts/search?q=Huang%20Poh%20Ching"> Huang Poh Ching</a>, <a href="https://publications.waset.org/abstracts/search?q=Chia%20Kai%20Xiang"> Chia Kai Xiang</a>, <a href="https://publications.waset.org/abstracts/search?q=H.%20V.%20Annegowda"> H.

These medicinal properties were believed to be related to the polyphenolic content present in G. procumbens extract, therefore optimization of its extraction process is vital to obtain highest possible antioxidant activities. The current study was conducted to investigate the effect of different concentrations of extracting solvent (ethanol) on the amount of polyphenolic content and antioxidant activities of G. procumbens leaf extract. The concentrations of ethanol used were 30-70%, with the temperature and time kept constant at 50°C and 30 minutes, respectively using ultrasound-assisted extraction. The polyphenolic content of these extracts were quantified by Folin-Ciocalteu colorimetric method and results were expressed as milligram gallic acid equivalent (mg GAE)/g. Phosphomolybdenum method and 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assays were used to investigate the antioxidant properties of the extract and the results were expressed as milligram ascorbic acid equivalent (mg AAE)/g and effective concentration (EC50) respectively. Among the three different (30%, 50% and 70%) concentrations of ethanol studied, the 50% ethanolic extract showed total phenolic content of 31.565 ± 0.344 mg GAE/g and total antioxidant activity of 78.839 ± 0.199 mg AAE/g while 30% ethanolic extract showed 29.214 ± 0.645 mg GAE/g and 70.701 ± 1.394 mg AAE/g, respectively. With respect to DPPH radical scavenging assay, 50% ethanolic extract had exhibited slightly lower EC50 (314.3 ± 4.0 μg/ml) values compared to 30% ethanol extract (340.4 ± 5.3 μg/ml). Out of all the tested extracts, 70% ethanolic extract exhibited significantly (p< 0.05) highest total phenolic content (38.000 ± 1.009 mg GAE/g), total antioxidant capacity (95.874 ± 2.422 mg AAE/g) and demonstrated the lowest EC50 in DPPH assay (244.2 ± 5.9 μg/ml). An excellent correlations were drawn between total phenolic content, total antioxidant capacity and DPPH radical scavenging activity (R2 = 0.949 and R2 = 0.978, respectively). It was concluded from this study that, 70% ethanol should be used as the optimal polarity solvent to obtain G. procumbens leaf extract with maximum polyphenolic content with antioxidant properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title="antioxidant activity">antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=DPPH%20assay" title=" DPPH assay"> DPPH assay</a>, <a href="https://publications.waset.org/abstracts/search?q=Gynura%20procumbens" title=" Gynura procumbens"> Gynura procumbens</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20compounds" title=" phenolic compounds"> phenolic compounds</a> </p> <a href="https://publications.waset.org/abstracts/42004/the-effect-of-different-concentrations-of-extracting-solvent-on-the-polyphenolic-content-and-antioxidant-activity-of-gynura-procumbens-leaves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42004.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">411</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">104</span> Hydrothermal Energy Application Technology Using Dam Deep Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yooseo%20Pang">Yooseo Pang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jongwoong%20Choi"> Jongwoong Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Cho"> Yong Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongchae%20Jeong"> Yongchae Jeong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Climate crisis, such as environmental problems related to energy supply, is getting emerged issues, so the use of renewable energy is essentially required to solve these problems, which are mainly managed by the Paris Agreement, the international treaty on climate change. The government of the Republic of Korea announced that the key long-term goal for a low-carbon strategy is “Carbon neutrality by 2050”. It is focused on the role of the internet data centers (IDC) in which large amounts of data, such as artificial intelligence (AI) and big data as an impact of the 4th industrial revolution, are managed. The demand for the cooling system market for IDC was about 9 billion US dollars in 2020, and 15.6% growth a year is expected in Korea. It is important to control the temperature in IDC with an efficient air conditioning system, so hydrothermal energy is one of the best options for saving energy in the cooling system. In order to save energy and optimize the operating conditions, it has been considered to apply ‘the dam deep water air conditioning system. Deep water at a specific level from the dam can supply constant water temperature year-round. It will be tested & analyzed the amount of energy saving with a pilot plant that has 100RT cooling capacity. Also, a target of this project is 1.2 PUE (Power Usage Effectiveness) which is the key parameter to check the efficiency of the cooling system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrothermal%20energy" title="hydrothermal energy">hydrothermal energy</a>, <a href="https://publications.waset.org/abstracts/search?q=HVAC" title=" HVAC"> HVAC</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20data%20center" title=" internet data center"> internet data center</a>, <a href="https://publications.waset.org/abstracts/search?q=free-cooling" title=" free-cooling"> free-cooling</a> </p> <a href="https://publications.waset.org/abstracts/162403/hydrothermal-energy-application-technology-using-dam-deep-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162403.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">81</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">103</span> The Interplay of Dietary Fibers and Intestinal Microbiota Affects Type 2 Diabetes by Generating Short-Chain Fatty Acids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Mazhar">Muhammad Mazhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Zhu"> Yong Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Likang%20Qin"> Likang Qin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Foods contain endogenous components known as dietary fibers, which are classified into soluble and insoluble forms. Dietary fibers are resistant to gut digestive enzymes, modulating anaerobic intestinal microbiota (AIM) and fabricating short-chain fatty acids (SCFAs). Acetate, butyrate, and propionate dominate in the gut, and different pathways, including Wood-Ljungdahl and acrylate pathways, generate these SCFAs. In pancreatic dysfunction, the release of insulin/glucagon is impaired, which leads to hyperglycemia. SCFAs enhance insulin sensitivity or secretion, beta-cell functions, leptin release, mitochondrial functions, and intestinal gluconeogenesis in human organs, which positively affect type 2 diabetes (T2D). Research models presented that SCFAs either enhance the release of peptide YY (PYY) and glucagon-like peptide-1 (GLP-1) from L-cells (entero-endocrine) or promote the release of leptin hormone satiation in adipose tissues through G-protein receptors, i.e., GPR-41/GPR-43. Dietary fibers are the components of foods that influence AIM and produce SCFAs, which may be offering beneficial effects on T2D. This review addresses the effectiveness of SCFAs in modulating gut AIM in the fermentation of dietary fiber and their worth against T2D. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dietary%20fibers" title="dietary fibers">dietary fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=intestinal%20microbiota" title=" intestinal microbiota"> intestinal microbiota</a>, <a href="https://publications.waset.org/abstracts/search?q=short-chain%20fatty%20acids" title=" short-chain fatty acids"> short-chain fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=type%202%20diabetes" title=" type 2 diabetes"> type 2 diabetes</a> </p> <a href="https://publications.waset.org/abstracts/174081/the-interplay-of-dietary-fibers-and-intestinal-microbiota-affects-type-2-diabetes-by-generating-short-chain-fatty-acids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174081.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">73</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">102</span> Customized Design of Amorphous Solids by Generative Deep Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yinghui%20Shang">Yinghui Shang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziqing%20Zhou"> Ziqing Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Rong%20Han"> Rong Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Hang%20Wang"> Hang Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaodi%20Liu"> Xiaodi Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Yang"> Yong Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The design of advanced amorphous solids, such as metallic glasses, with targeted properties through artificial intelligence signifies a paradigmatic shift in physical metallurgy and materials technology. Here, we developed a machine-learning architecture that facilitates the generation of metallic glasses with targeted multifunctional properties. Our architecture integrates the state-of-the-art unsupervised generative adversarial network model with supervised models, allowing the incorporation of general prior knowledge derived from thousands of data points across a vast range of alloy compositions, into the creation of data points for a specific type of composition, which overcame the common issue of data scarcity typically encountered in the design of a given type of metallic glasses. Using our generative model, we have successfully designed copper-based metallic glasses, which display exceptionally high hardness or a remarkably low modulus. Notably, our architecture can not only explore uncharted regions in the targeted compositional space but also permits self-improvement after experimentally validated data points are added to the initial dataset for subsequent cycles of data generation, hence paving the way for the customized design of amorphous solids without human intervention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metallic%20glass" title="metallic glass">metallic glass</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20property" title=" mechanical property"> mechanical property</a>, <a href="https://publications.waset.org/abstracts/search?q=automated%20generation" title=" automated generation"> automated generation</a> </p> <a href="https://publications.waset.org/abstracts/186520/customized-design-of-amorphous-solids-by-generative-deep-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186520.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">56</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">101</span> Development of a Work-Related Stress Management Program Guaranteeing Fitness-For-Duty for Human Error Prevention</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyeon-Kyo%20Lim">Hyeon-Kyo Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Tong-Il%20Jang"> Tong-Il Jang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Hee%20Lee"> Yong-Hee Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Human error is one of the most dreaded factors that may result in unexpected accidents, especially in nuclear power plants. For accident prevention, it is quite indispensable to analyze and to manage the influence of any factor which may raise the possibility of human errors. Out of lots factors, stress has been reported to have a significant influence on human performance. Therefore, this research aimed to develop a work-related stress management program which can guarantee Fitness-for-Duty (FFD) of the workers in nuclear power plants, especially those working in main control rooms. Major stress factors were elicited through literal surveys and classified into major categories such as demands, supports, and relationships. To manage those factors, a test and intervention program based on 4-level approaches was developed over the whole employment cycle including selection and screening of workers, job allocation, and job rotation. In addition, a managerial care program was introduced with the concept of Employee-Assistance-Program (EAP) program. Reviews on the program conducted by ex-operators in nuclear power plants showed responses in the affirmative, and suggested additional treatment to guarantee high performance of human workers, not in normal operations but also in emergency situations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20error" title="human error">human error</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20performance" title=" work performance"> work performance</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20stress" title=" work stress"> work stress</a>, <a href="https://publications.waset.org/abstracts/search?q=Fitness-For-Duty%20%28FFD%29" title=" Fitness-For-Duty (FFD)"> Fitness-For-Duty (FFD)</a>, <a href="https://publications.waset.org/abstracts/search?q=Employee%20Assistance%20Program%20%28EAP%29" title=" Employee Assistance Program (EAP)"> Employee Assistance Program (EAP)</a> </p> <a href="https://publications.waset.org/abstracts/67509/development-of-a-work-related-stress-management-program-guaranteeing-fitness-for-duty-for-human-error-prevention" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67509.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">404</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">100</span> The Impact of Character Strengths on Employee Well-Being: The Mediating Effect of Work-Family Relationship</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jing%20Wang">Jing Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Wang"> Yong Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For organizational development, employee well-being is critical and has been influenced deeply by character strengths. Therefore, investigating the relationship between character strengths and employee well-being and its inner mechanism is crucial. In this study, we explored the features of Chinese employees' character strengths, studied the relationship between character strengths and employees' subjective well-being, work well-being and psychological well-being respectively, and examined the mediating effect of work-family relationship (both enrichment and conflict). An online survey was conducted. The results showed that: (1) The top five character strengths of Chinese employees were gratitude, citizenship, kindness, appreciation of beauty and excellence, justice, while the bottom five ones were creativity, authenticity, bravery, spirituality, open-mindedness. (2) Subjective well-being was significantly correlated to courage, humanity, transcendence and justice. Work well-being was significantly correlated to wisdom, courage, humanity, justice and transcendence. Psychological well-being was significantly correlated to all the above five character strengths and temperance. (3) Wisdom and humanity influenced Chinese employees’ subjective well-being through work-family enrichment. Justice enhanced psychological well-being via work-family enrichment; meanwhile, it also played a positive role in subjective well-being, work well-being, and psychological well-being by decreasing the family-work conflict. At the end of this paper, some theoretical and practical contributions to organizational management were further discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=character%20strengths" title="character strengths">character strengths</a>, <a href="https://publications.waset.org/abstracts/search?q=work-family%20conflict" title=" work-family conflict"> work-family conflict</a>, <a href="https://publications.waset.org/abstracts/search?q=work-family%20enrichment" title=" work-family enrichment"> work-family enrichment</a>, <a href="https://publications.waset.org/abstracts/search?q=employee%20well-being" title=" employee well-being"> employee well-being</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20well-being" title=" work well-being"> work well-being</a> </p> <a href="https://publications.waset.org/abstracts/48149/the-impact-of-character-strengths-on-employee-well-being-the-mediating-effect-of-work-family-relationship" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48149.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">390</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">99</span> An Open-Label Phase I Clinical Study: Safety, Tolerability and Pharmacodynamics of Mutant Collagenase Injection in Adults for Localized Fat Reduction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yong%20Cang">Yong Cang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> RJV001 is a subcutaneous injection containing mutated recombinant Collagenase H (ColH), leading to disruption of collagen matrix in adipose tissue and programmed cell death of adipocytes. Here we reported our clinical investigation of the safety, tolerance and pharmacodynamics of localized RJV001 injection into healthy human abdominal fat tissues (NCT04821648, Arizona Research Center). Investigate the safety, tolerance and clinical pharmacodynamics of subcutaneous RJV001 in humans. In the dose-escalating study, 18 subjects completed the study, 100% female, 78% white, with a mean age of 42[±9.9]. All three tested dose (0.05, 0.075 and 0.15 mg/injection), up to 30 injections, were safe and well-tolerated. Bruising and tenderness to palpation, mild to moderate, were the most frequent local skin reactions but nearly all resolved within 30 days. Additionally, physician-monitored ultrasound measurement showed that a reduction in abdominal fat tissue thickness was consistently observed in Cohort C (0.075, 0.15 mg/injection, 30injections), with a mean reduction of 7.37 [± 2.020] mm. Based on this clinical study, RJV001 has been advanced to phase II clinical studies. In the dose-escalating study, subcutaneously administered RJV001 was safe and well-tolerated in healthy adults up to 0.15 mg/injection, 30 injections.

But therapeutic options are limited to treat cryptococcosis. Some signaling pathways including cyclic AMP pathway, MAPK pathway, and calcineurin pathway play a central role in the regulation of the growth, differentiation, and virulence of C. neoformans. To understand signaling networks regulating the virulence of C. neoformans, we selected the 114 putative phosphatase genes, one of the major components of signaling networks, in the genome of C. neoformans. We identified putative phosphatases based on annotation in C. neoformans var. grubii genome database provided by the Broad Institute and National Center for Biotechnology Information (NCBI) and performed a BLAST search of phosphatases of Saccharomyces cerevisiae, Aspergillus nidulans, Candida albicans and Fusarium graminearum to Cryptococcus neoformans. We classified putative phosphatases into 14 groups based on InterPro phosphatase domain annotation. Here, we constructed 170 signature-tagged gene-deletion strains through homologous recombination methods for 91 putative phosphatases. We examined their phenotypic traits under 30 different in vitro conditions, including growth, differentiation, stress response, antifungal resistance and virulence-factor production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20fungal%20pathogen" title="human fungal pathogen">human fungal pathogen</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphatase" title=" phosphatase"> phosphatase</a>, <a href="https://publications.waset.org/abstracts/search?q=deletion%20library" title=" deletion library"> deletion library</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20genomics" title=" functional genomics"> functional genomics</a> </p> <a href="https://publications.waset.org/abstracts/63313/genome-wide-functional-analysis-of-phosphatase-in-cryptococcus-neoformans" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63313.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">364</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">97</span> The Appropriate Number of Test Items That a Classroom-Based Reading Assessment Should Include: A Generalizability Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jui-Teng%20Liao">Jui-Teng Liao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The selected-response (SR) format has been commonly adopted to assess academic reading in both formal and informal testing (i.e., standardized assessment and classroom assessment) because of its strengths in content validity, construct validity, as well as scoring objectivity and efficiency. When developing a second language (L2) reading test, researchers indicate that the longer the test (e.g., more test items) is, the higher reliability and validity the test is likely to produce. However, previous studies have not provided specific guidelines regarding the optimal length of a test or the most suitable number of test items or reading passages. Additionally, reading tests often include different question types (e.g., factual, vocabulary, inferential) that require varying degrees of reading comprehension and cognitive processes. Therefore, it is important to investigate the impact of question types on the number of items in relation to the score reliability of L2 reading tests. Given the popularity of the SR question format and its impact on assessment results on teaching and learning, it is necessary to investigate the degree to which such a question format can reliably measure learners’ L2 reading comprehension. The present study, therefore, adopted the generalizability (G) theory to investigate the score reliability of the SR format in L2 reading tests focusing on how many test items a reading test should include. Specifically, this study aimed to investigate the interaction between question types and the number of items, providing insights into the appropriate item count for different types of questions. G theory is a comprehensive statistical framework used for estimating the score reliability of tests and validating their results. Data were collected from 108 English as a second language student who completed an English reading test comprising factual, vocabulary, and inferential questions in the SR format. The computer program mGENOVA was utilized to analyze the data using multivariate designs (i.e., scenarios). Based on the results of G theory analyses, the findings indicated that the number of test items had a critical impact on the score reliability of an L2 reading test. Furthermore, the findings revealed that different types of reading questions required varying numbers of test items for reliable assessment of learners’ L2 reading proficiency. Further implications for teaching practice and classroom-based assessments are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=second%20language%20reading%20assessment" title="second language reading assessment">second language reading assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=validity%20and%20reliability" title=" validity and reliability"> validity and reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=Generalizability%20theory" title=" Generalizability theory"> Generalizability theory</a>, <a href="https://publications.waset.org/abstracts/search?q=Academic%20reading" title=" Academic reading"> Academic reading</a>, <a href="https://publications.waset.org/abstracts/search?q=Question%20format" title=" Question format"> Question format</a> </p> <a href="https://publications.waset.org/abstracts/168914/the-appropriate-number-of-test-items-that-a-classroom-based-reading-assessment-should-include-a-generalizability-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168914.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">96</span> Research on Steam Injection Technology of Extended Range Engine Cylinder for Waste Heat Recovery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhiyuan%20Jia">Zhiyuan Jia</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiuxiu%20Sun"> Xiuxiu Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Chen"> Yong Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Liu%20Hai"> Liu Hai</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuangqing%20Li"> Shuangqing Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The engine cooling water and exhaust gas contain a large amount of available energy.

Then, the effects of single and multiple protease treatments were determined with respect to contents of soluble solid (SS) and soluble nitrogen, sensory attributes, electrophoretic profiles, and HPLC peak patterns of the fish hydrolyzates (FHs) from various species. The contents of SS of the FHs were quite species-specific and the hydrolyzates of halibut showed the highest SS contents. At this point, multiple protease treatment increased SS content conspicuously in all fish tested. The contents of total soluble nitrogen and TCA-soluble nitrogen were well correlated with those of SS irrespective of fish species and methods of enzyme treatment. Also, it was noticed that multiple protease treatment improved sensory attributes of the FHs considerably. Electropherograms of the FHs showed fast migrating peptide bands that had the molecular masses mostly lower than 1 kDa and this was confirmed by peptide patterns from HPLC analysis for some FHs that had good sensory quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=production" title="production">production</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20hydrolyzates" title=" fish hydrolyzates"> fish hydrolyzates</a>, <a href="https://publications.waset.org/abstracts/search?q=protease%20treatments" title=" protease treatments"> protease treatments</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20pressure" title=" high pressure"> high pressure</a> </p> <a href="https://publications.waset.org/abstracts/2490/production-of-fish-hydrolyzates-by-single-and-multiple-protease-treatments-under-medium-high-pressure-of-300-mpa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2490.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">283</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">94</span> Evaluation of Urban-Rural Integration of Characteristic Towns in Yunnan Province</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huang%20Yong">Huang Yong</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen%20Qianting"> Chen Qianting</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhao%20Shurong"> Zhao Shurong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to identify the role and effect of Characteristic Towns as an important means to promote urban-rural integration, this paper uses Flow Theory and complex network analysis methods to jointly construct the identification path of urban-rural integration capabilities of Characteristic Towns.

The study found that in the implementation of the National Characteristic Town Project in Yunnan Province, (1) the population is more susceptible to the impact of the Characteristic Town Project than the technical elements, but the stability is poor; (2) The flow capacity of urban and rural technical elements is weak, and the quality of the enterprise cooperation network in general; (3) Compared with the batch of Characteristic Towns in 2016, its ability to promote urban-rural integration is higher in 2017; (4) The role of the Characteristic Town Project on urban-rural integration focuses on the improvement of the number of urban and rural flow elements. This paper analyzes the mode of the role of Characteristic Towns on urban-rural integration from the perspective of ‘flow,’ establishes a research paradigm for evaluating the role of Characteristic Towns in urban-rural integration capabilities, and builds a path for the application of Characteristic Towns to support the realization of urban-rural integration goals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=characteristic%20town" title="characteristic town">characteristic town</a>, <a href="https://publications.waset.org/abstracts/search?q=urban-rural%20integration" title=" urban-rural integration"> urban-rural integration</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20theory" title=" flow theory"> flow theory</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20network%20analysis" title=" complex network analysis"> complex network analysis</a> </p> <a href="https://publications.waset.org/abstracts/152072/evaluation-of-urban-rural-integration-of-characteristic-towns-in-yunnan-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152072.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">93</span> Signal Amplification Using Graphene Oxide in Label Free Biosensor for Pathogen Detection </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agampodi%20Promoda%20Perera">Agampodi Promoda Perera</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Shin"> Yong Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mi%20Kyoung%20Park"> Mi Kyoung Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The successful detection of pathogenic bacteria in blood provides important information for early detection, diagnosis and the prevention and treatment of infectious diseases. Silicon microring resonators are refractive-index-based optical biosensors that provide highly sensitive, label-free, real-time multiplexed detection of biomolecules. We demonstrate the technique of using GO (graphene oxide) to enhance the signal output of the silicon microring optical sensor. The activated carboxylic groups in GO molecules bind directly to single stranded DNA with an amino modified 5’ end. This conjugation amplifies the shift in resonant wavelength in a real-time manner. We designed a capture probe for strain Staphylococcus aureus of 21 bp and a longer complementary target sequence of 70 bp. The mismatched target sequence we used was of Streptococcus agalactiae of 70 bp. GO is added after the complementary binding of the probe and target. GO conjugates to the unbound single stranded segment of the target and increase the wavelength shift on the silicon microring resonator. Furthermore, our results show that GO could successfully differentiate between the mismatched DNA sequences from the complementary DNA sequence. Therefore, the proposed concept could effectively enhance sensitivity of pathogen detection sensors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=label%20free%20biosensor" title="label free biosensor">label free biosensor</a>, <a href="https://publications.waset.org/abstracts/search?q=pathogenic%20bacteria" title=" pathogenic bacteria"> pathogenic bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20oxide" title=" graphene oxide"> graphene oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a> </p> <a href="https://publications.waset.org/abstracts/12619/signal-amplification-using-graphene-oxide-in-label-free-biosensor-for-pathogen-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12619.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">467</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">92</span> Thermal Analysis and Computational Fluid Dynamics Simulation of Large-Scale Cryopump</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yue%20Shuai%20Zhao">Yue Shuai Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Rong%20Ping%20Shao"> Rong Ping Shao</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Sun"> Wei Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Guo%20Hua%20Ren"> Guo Hua Ren</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Wang"> Yong Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Chen%20Sun"> Li Chen Sun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A large-scale cryopump (DN1250) used in large vacuum leak detecting system was designed and its performance experimentally investigated by Beijing Institute of Spacecraft Environment Engineering. The cryopump was cooled by four closed cycle helium refrigerators (two dual stage refrigerators and two single stage refrigerators). Detailed numerical analysis of the heat transfer in the first stage array and the second stage array were performed by using computational fluid dynamic method (CFD). Several design parameters were considered to find the effect on the temperature distribution and the cooldown time. The variation of thermal conductivity and heat capacity with temperature was taken into account. The thermal analysis method based on numerical techniques was introduced in this study, the heat transfer in the first stage array and the second stage cryopanel was carefully analyzed to determine important considerations in the thermal design of the cryopump. A performance test system according to the RNEUROP standards was built to test main performance of the cryopump. The experimental results showed that the structure of first stage array which was optimized by the method could meet the requirement of the cryopump well. The temperature of the cryopanel was down to 10K within 300 min, and the result of the experiment was accordant with theoretical analysis' conclusion. The test also showed that the pumping speed for N2 of the pump was up to 57,000 L/s, and the crossover was over than 300,000 Pa•L. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryopump" title="cryopump">cryopump</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20distribution" title=" temperature distribution"> temperature distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20analysis" title=" thermal analysis"> thermal analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD%20Simulation" title=" CFD Simulation"> CFD Simulation</a> </p> <a href="https://publications.waset.org/abstracts/62288/thermal-analysis-and-computational-fluid-dynamics-simulation-of-large-scale-cryopump" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62288.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">304</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">91</span> Flame Volume Prediction and Validation for Lean Blowout of Gas Turbine Combustor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ejaz%20Ahmed">Ejaz Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Huang%20Yong"> Huang Yong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The operation of aero engines has a critical importance in the vicinity of lean blowout (LBO) limits. Lefebvre’s model of LBO based on empirical correlation has been extended to flame volume concept by the authors. The flame volume takes into account the effects of geometric configuration, the complex spatial interaction of mixing, turbulence, heat transfer and combustion processes inside the gas turbine combustion chamber. For these reasons, flame volume based LBO predictions are more accurate. Although LBO prediction accuracy has improved, it poses a challenge associated with Vf estimation in real gas turbine combustors. This work extends the approach of flame volume prediction previously based on fuel iterative approximation with cold flow simulations to reactive flow simulations. Flame volume for 11 combustor configurations has been simulated and validated against experimental data. To make prediction methodology robust as required in the preliminary design stage, reactive flow simulations were carried out with the combination of probability density function (PDF) and discrete phase model (DPM) in FLUENT 15.0. The criterion for flame identification was defined. Two important parameters i.e. critical injection diameter (Dp,crit) and critical temperature (Tcrit) were identified, and their influence on reactive flow simulation was studied for Vf estimation. Obtained results exhibit ±15% error in Vf estimation with experimental data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=combustion" title=" combustion"> combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20turbine%20combustor" title=" gas turbine combustor"> gas turbine combustor</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20blowout" title=" lean blowout"> lean blowout</a> </p> <a href="https://publications.waset.org/abstracts/54345/flame-volume-prediction-and-validation-for-lean-blowout-of-gas-turbine-combustor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54345.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">268</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">90</span> Carbon Emission Reduction by Compact City Construction in Toyama, Japan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benyan%20Jiang">Benyan Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Dawei%20Xia"> Dawei Xia</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Li"> Yong Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Compact city construction is considered as an effective measure to reduce carbon emission in city lives. Toyama City started its compact city strategy in 2000 and was selected as a Japanese Environmental Model City in 2008 for its achievement. This paper takes Toyama as a study case, aiming to find how city polices affected people’s life styles and reduced carbon emission. The main materials used in this study are first-hand documents, like urban planning materials, government annual report and statistic data from transportation association. It is found that the main measures taken by Toyama City include the construction of light rail transit, increasing the frequency of buses, building park and ride parking lots. In addition to hardware facilities, it also offers flexible policies like passengers' coupons for the senior citizens and free use of parking lots by buying shopping vouchers. Besides, Toyama City encourages citizens to live within 500 meters of public transportation. People who buy an apartment near public transportation will receive 500,000 Japanese Yen. These measures have proven to their effects. Compared with 2005, in 2014, the transportation sector reduced emissions of 2.35 million tons of CO₂, 13.6%. This aspect is related to the increase in the number of cars in public transport and also related to fuel improvement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Toyama" title="Toyama">Toyama</a>, <a href="https://publications.waset.org/abstracts/search?q=compact%20city" title=" compact city"> compact city</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20transportation" title=" public transportation"> public transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20reduction" title=" CO₂ reduction"> CO₂ reduction</a> </p> <a href="https://publications.waset.org/abstracts/100970/carbon-emission-reduction-by-compact-city-construction-in-toyama-japan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100970.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">89</span> Bifid Ureters: Arising Directly from the Separate Calyces and Renal Pelvis of the Kidney: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuri%20Seu">Yuri Seu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Jin%20Park"> Hyun Jin Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Seo%20Park"> Jin Seo Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Suk%20Moon"> Yong-Suk Moon</a>, <a href="https://publications.waset.org/abstracts/search?q=HongtaeKim"> HongtaeKim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mi-Sun%20Hur"> Mi-Sun Hur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present case report describes bifid ureters arising directly from the separate calyces and renal pelvis of the kidney. It was a single common ureter leading away from the bladder, which was separated into incompletely duplicated ureters near the level of the anterior superior iliac supine. These two branches then entered the left kidney through their own courses. Each ureter traveled anterior and posterior to the renal vein, respectively. These two ureters formed a Y-shaped pattern. One ureter coursed anterior to the renal vein with shorter length, and it terminated at the renal pelvis that was divided into major calices in approximately lower two thirds of the kidney. The other ureter coursed posterior to the renal vein with longer length, terminating at approximately the upper third of the kidney. The renal calices in the upper third of the kidney were directly connected to the posterior ureter, whereas the other major calices in the lower two thirds of the kidney formed the renal pelvis connecting to the anterior ureter. Thus, convergence of the major calices was separated according to the terminations of two ureters. These anomalous ureters were traced to the calices of the kidney, thereby providing a reference of a rare variation of the ureter. The bifid ureters arising from the separate calyces and renal pelvis should be considered by radiologists when evaluating images and diagnosing possible complications of these anomalies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bifid%20ureters" title="bifid ureters">bifid ureters</a>, <a href="https://publications.waset.org/abstracts/search?q=kidney" title=" kidney"> kidney</a>, <a href="https://publications.waset.org/abstracts/search?q=major%20calices" title=" major calices"> major calices</a>, <a href="https://publications.waset.org/abstracts/search?q=renal%20pelvis" title=" renal pelvis"> renal pelvis</a> </p> <a href="https://publications.waset.org/abstracts/167715/bifid-ureters-arising-directly-from-the-separate-calyces-and-renal-pelvis-of-the-kidney-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167715.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">86</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">88</span> Upconversion Nanoparticles for Imaging and Controlled Photothermal Release of Anticancer Drug in Breast Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rishav%20Shrestha">Rishav Shrestha</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Zhang"> Yong Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Anti-Stoke upconversion process has been used extensively for bioimaging and is recently being used for photoactivated therapy in cancer utilizing upconversion nanoparticles (UCNs). The UCNs have an excitation band at 980nm; 980nm laser excitation used to produce UV/Visible emissions also produce a heating effect. Light-to-heat conversion has been observed in nanoparticles(NPs) doped with neodymium(Nd) or ytterbium(Yb)/erbium(Er) ions. Despite laser-induced heating in Rare-earth doped NPs being proven to be a relatively efficient process, only few attempts to use them as photothermal agents in biosystems have been made up to now. Gold nanoparticles and carbon nanotubes are the most researched and developed for photothermal applications. Both have large heating efficiency and outstanding biocompatibility. However, they show weak fluorescence which makes them harder to track in vivo. In that regard, UCNs are attractive due to their excellent optical features in addition to their light-to-heat conversion and excitation by NIR, for imaging and spatiotemporally releasing drugs. In this work, we have utilized a simple method to coat Nd doped UCNs with thermoresponsive polymer PNIPAM on which 4-Hydroxytamoxifen (4-OH-T) is loaded. Such UCNs demonstrate a high loading efficiency and low leakage of 4-OH-T. Encouragingly, the release of 4-OH-T can be modulated by varying the power and duration of the NIR. Such UCNs were then used to demonstrate imaging and controlled photothermal release of 4-OH-T in MCF-7 breast cancer cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer%20therapy" title="cancer therapy">cancer therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=controlled%20release" title=" controlled release"> controlled release</a>, <a href="https://publications.waset.org/abstracts/search?q=photothermal%20release" title=" photothermal release"> photothermal release</a>, <a href="https://publications.waset.org/abstracts/search?q=upconversion%20nanoparticles" title=" upconversion nanoparticles"> upconversion nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/24020/upconversion-nanoparticles-for-imaging-and-controlled-photothermal-release-of-anticancer-drug-in-breast-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24020.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">422</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">87</span> Real-Time Pedestrian Detection Method Based on Improved YOLOv3</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jingting%20Luo">Jingting Luo</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Wang"> Yong Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying%20Wang"> Ying Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pedestrian detection in image or video data is a very important and challenging task in security surveillance. The difficulty of this task is to locate and detect pedestrians of different scales in complex scenes accurately. To solve these problems, a deep neural network (RT-YOLOv3) is proposed to realize real-time pedestrian detection at different scales in security monitoring. RT-YOLOv3 improves the traditional YOLOv3 algorithm. Firstly, the deep residual network is added to extract vehicle features. Then six convolutional neural networks with different scales are designed and fused with the corresponding scale feature maps in the residual network to form the final feature pyramid to perform pedestrian detection tasks. This method can better characterize pedestrians. In order to further improve the accuracy and generalization ability of the model, a hybrid pedestrian data set training method is used to extract pedestrian data from the VOC data set and train with the INRIA pedestrian data set. Experiments show that the proposed RT-YOLOv3 method achieves 93.57% accuracy of mAP (mean average precision) and 46.52f/s (number of frames per second). In terms of accuracy, RT-YOLOv3 performs better than Fast R-CNN, Faster R-CNN, YOLO, SSD, YOLOv2, and YOLOv3. This method reduces the missed detection rate and false detection rate, improves the positioning accuracy, and meets the requirements of real-time detection of pedestrian objects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pedestrian%20detection" title="pedestrian detection">pedestrian detection</a>, <a href="https://publications.waset.org/abstracts/search?q=feature%20detection" title=" feature detection"> feature detection</a>, <a href="https://publications.waset.org/abstracts/search?q=convolutional%20neural%20network" title=" convolutional neural network"> convolutional neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=real-time%20detection" title=" real-time detection"> real-time detection</a>, <a href="https://publications.waset.org/abstracts/search?q=YOLOv3" title=" YOLOv3"> YOLOv3</a> </p> <a href="https://publications.waset.org/abstracts/114446/real-time-pedestrian-detection-method-based-on-improved-yolov3" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114446.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">86</span> Development of pm2.5 Forecasting System in Seoul, South Korea Using Chemical Transport Modeling and ConvLSTM-DNN</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ji-Seok%20Koo">Ji-Seok Koo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hee%E2%80%91Yong%20Kwon"> Hee‑Yong Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Hui-Young%20Yun"> Hui-Young Yun</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung-Hui%20Wang"> Kyung-Hui Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Youn-Seo%20Koo"> Youn-Seo Koo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a forecasting system for PM2.5 levels in Seoul, South Korea, leveraging a combination of chemical transport modeling and ConvLSTM-DNN machine learning technology. Exposure to PM2.5 has known detrimental impacts on public health, making its prediction crucial for establishing preventive measures. Existing forecasting models, like the Community Multiscale Air Quality (CMAQ) and Weather Research and Forecasting (WRF), are hindered by their reliance on uncertain input data, such as anthropogenic emissions and meteorological patterns, as well as certain intrinsic model limitations. The system we've developed specifically addresses these issues by integrating machine learning and using carefully selected input features that account for local and distant sources of PM2.5. In South Korea, the PM2.5 concentration is greatly influenced by both local emissions and long-range transport from China, and our model effectively captures these spatial and temporal dynamics. Our PM2.5 prediction system combines the strengths of advanced hybrid machine learning algorithms, convLSTM and DNN, to improve upon the limitations of the traditional CMAQ model. Data used in the system include forecasted information from CMAQ and WRF models, along with actual PM2.5 concentration and weather variable data from monitoring stations in China and South Korea. The system was implemented specifically for Seoul's PM2.5 forecasting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PM2.5%20forecast" title="PM2.5 forecast">PM2.5 forecast</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=convLSTM" title=" convLSTM"> convLSTM</a>, <a href="https://publications.waset.org/abstracts/search?q=DNN" title=" DNN"> DNN</a> </p> <a href="https://publications.waset.org/abstracts/169596/development-of-pm25-forecasting-system-in-seoul-south-korea-using-chemical-transport-modeling-and-convlstm-dnn" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169596.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">54</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">85</span> Performance Comparison of Resource Allocation without Feedback in Wireless Body Area Networks by Various Pseudo Orthogonal Sequences</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ojin%20Kwon">Ojin Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Jin%20Yoon"> Yong-Jin Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Liu%20Xin"> Liu Xin</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Hongbao"> Zhang Hongbao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wireless Body Area Network (WBAN) is a short-range wireless communication around human body for various applications such as wearable devices, entertainment, military, and especially medical devices. WBAN attracts the attention of continuous health monitoring system including diagnostic procedure, early detection of abnormal conditions, and prevention of emergency situations. Compared to cellular network, WBAN system is more difficult to control inter- and inner-cell interference due to the limited power, limited calculation capability, mobility of patient, and non-cooperation among WBANs. In this paper, we compare the performance of resource allocation scheme based on several Pseudo Orthogonal Codewords (POCs) to mitigate inter-WBAN interference. Previously, the POCs are widely exploited for a protocol sequence and optical orthogonal code. Each POCs have different properties of auto- and cross-correlation and spectral efficiency according to its construction of POCs. To identify different WBANs, several different pseudo orthogonal patterns based on POCs exploits for resource allocation of WBANs. By simulating these pseudo orthogonal resource allocations of WBANs on MATLAB, we obtain the performance of WBANs according to different POCs and can analyze and evaluate the suitability of POCs for the resource allocation in the WBANs system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wireless%20body%20area%20network" title="wireless body area network">wireless body area network</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20sensor%20network" title=" body sensor network"> body sensor network</a>, <a href="https://publications.waset.org/abstracts/search?q=resource%20allocation%20without%20feedback" title=" resource allocation without feedback"> resource allocation without feedback</a>, <a href="https://publications.waset.org/abstracts/search?q=interference%20mitigation" title=" interference mitigation"> interference mitigation</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudo%20orthogonal%20pattern" title=" pseudo orthogonal pattern"> pseudo orthogonal pattern</a> </p> <a href="https://publications.waset.org/abstracts/9490/performance-comparison-of-resource-allocation-without-feedback-in-wireless-body-area-networks-by-various-pseudo-orthogonal-sequences" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9490.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">353</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">84</span> Calculating Approach of Thermal Conductivity of 8 YSZ in Different Relative Humidities Corresponding to Low Water Contents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yun%20Chol%20Kang">Yun Chol Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Myong%20Nam%20Kong"> Myong Nam Kong</a>, <a href="https://publications.waset.org/abstracts/search?q=Nam%20Chol%20Yu"> Nam Chol Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Sim%20Kim"> Jin Sim Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Un%20Yong%20Paek"> Un Yong Paek</a>, <a href="https://publications.waset.org/abstracts/search?q=Song%20Ho%20Kim"> Song Ho Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focuses on the calculating approach of the thermal conductivity of 8 mol% yttria-stabilized zirconia (8YSZ) in different relative humidity corresponding to low water contents. When water content in 8YSZ is low, water droplets can accumulate in the neck regions. We assume that spherical water droplets are randomly located in the neck regions formed by grains and surrounded by the pores. Based on this, a new hypothetical pore constituted by air and water is proposed using the microstructural modeling. We consider 8YSZ is a two-phase material constituted by the solid region and the hypothetical pore region where the water droplets are penetrated in the pores, randomly. The results showed that the thermal conductivity of the hypothetical pore is calculated using the parallel resistance for low water contents, and the effective thermal conductivity of 8YSZ material constituted by solid and hypothetical pore in different relative humidities using EMPT. When the numbers of water layers on the surface of 8YSZ are less than 1.5, the proposed approach gives a good interpretation of the experimental results. When the theoretical value of the number of water layers on 8YSZ surface is 1, the water content is not enough to cover the internal solid surface completely. The proposed approach gives a better interpretation of the experimental results in different relative humidities that numbers of water layers on the surface of 8YSZ are less than 1.5. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=8YSZ" title="8YSZ">8YSZ</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20conductivity" title=" thermal conductivity"> thermal conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20humidity" title=" relative humidity"> relative humidity</a> </p> <a href="https://publications.waset.org/abstracts/168365/calculating-approach-of-thermal-conductivity-of-8-ysz-in-different-relative-humidities-corresponding-to-low-water-contents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168365.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">88</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">83</span> The Development of a Residual Stress Measurement Method for Roll Formed Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yong%20Sun">Yong Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20Luzin"> Vladimir Luzin</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhen%20Qian"> Zhen Qian</a>, <a href="https://publications.waset.org/abstracts/search?q=William%20J.%20T.%20Daniel"> William J.

This is due to the occurrence of redundant plastic deformation in roll forming process and it can cause various product defects. Although the residual stresses of a roll formed product consist of longitudinal and transverse residual stresses components, but the longitudinal residual stresses plays a key role to the product defects of a roll formed product and therefore, only the longitudinal residual stresses concerned by the roll forming scholars and engineers. However, how to inspect the residual stresses of a product quickly and economically as a routine operation is still a challenge. This paper introduces a residual stresses measurement method called slope cutting method to study the longitudinal residual stresses through layers geometrically to a roll formed products or a product with similar process such as a rolled sheet. The detailed measuring procedure is given and discussed. The residual stresses variation through the layer can be derived based on the variation of curvature in different layers and steps. The slope cutting method has been explored and validated by experimental study on a roll-formed square tube. The neutron diffraction method is applied to validate the accuracy of the newly proposed layering removal materials results. The two set results agree with each other very well and therefore, the method is expected to be a routine testing method to monitor the quality of a product been formed and that is a great impact to roll forming industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=roll%20forming" title="roll forming">roll forming</a>, <a href="https://publications.waset.org/abstracts/search?q=residual%20stress" title=" residual stress"> residual stress</a>, <a href="https://publications.waset.org/abstracts/search?q=measurement%20method" title=" measurement method"> measurement method</a>, <a href="https://publications.waset.org/abstracts/search?q=neutron%20diffraction" title=" neutron diffraction"> neutron diffraction</a> </p> <a href="https://publications.waset.org/abstracts/51177/the-development-of-a-residual-stress-measurement-method-for-roll-formed-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51177.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">365</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">82</span> Regioselective Nucleophilic Substitution of the Baylis-Hillman Adducts with Iodine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahid%20Shafiq">Zahid Shafiq</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Liu"> Li Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Wang"> Dong Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Jun%20Chen"> Yong-Jun Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As synthetic organic methods are increasingly concerned with the growing importance of sustainable chemistry, iodine recently has emerged as an inexpensive, non-toxic, readily available and environmentally benign catalyst for various organic transformations to afford the corresponding products in high yields with high regio- and chemoselectivity. Iodine has found widespread applications in various organic synthesis such as Michael addition, coupling reaction and also in the multicomponent synthesis where it can efficiently activate C=C, C=O, C=N, and so forth. Iodine not only has been shown to be an efficient mild Lewis acid in various processes, but also due to its moderate nature, and water tolerance, reactions catalyzed by iodine can be effectively carried out in neutral media under very mild conditions. We have successfully described an efficient procedure for the nucleophilic substitution of the Baylis-Hillman (BH) adducts and their corresponding acetates with indoles to get α-substitution product using catalytic Silver Triflate (AgOTf) as Lewis acid. At this point, we were interested to develop an environmentally benign catalytic system to effect this substitution reaction and to avoid the use of metal Lewis acid as a catalyst. Since, we observed the formation of -product during the course of the reaction, we also became interested to explore the reaction conditions in order to control regioselectivity and to obtain both regioisomers. The developed methodology resulted in regioselective substitution products with controlled selectivity. Further, the substitution products were used to synthesize various Tri- and Tetracyclo Azepino indole derivatives via reductive amination. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=indole" title="indole">indole</a>, <a href="https://publications.waset.org/abstracts/search?q=regioselective" title=" regioselective"> regioselective</a>, <a href="https://publications.waset.org/abstracts/search?q=Baylis-Hillman" title=" Baylis-Hillman"> Baylis-Hillman</a>, <a href="https://publications.waset.org/abstracts/search?q=substitution" title=" substitution"> substitution</a> </p> <a href="https://publications.waset.org/abstracts/110900/regioselective-nucleophilic-substitution-of-the-baylis-hillman-adducts-with-iodine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110900.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">198</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">81</span> Analysis and Experimental Research on the Influence of Lubricating Oil on the Transmission Efficiency of New Energy Vehicle Gearbox</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chen%20Yong">Chen Yong</a>, <a href="https://publications.waset.org/abstracts/search?q=Bi%20Wangyang"> Bi Wangyang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zang%20Libin"> Zang Libin</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Jinkai"> Li Jinkai</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheng%20Xiaowei"> Cheng Xiaowei</a>, <a href="https://publications.waset.org/abstracts/search?q=Liu%20Jinmin"> Liu Jinmin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu%20Miao"> Yu Miao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> New energy vehicle power transmission systems continue to develop in the direction of high torque, high speed, and high efficiency. The cooling and lubrication of the motor and the transmission system are integrated, and new requirements are placed on the lubricants for the transmission system. The effects of traditional lubricants and special lubricants for new energy vehicles on transmission efficiency were studied through experiments and simulation methods. A mathematical model of the transmission efficiency of the lubricating oil in the gearbox was established. The power loss of each part was analyzed according to the working conditions. The relationship between the speed and the characteristics of different lubricating oil products on the power loss of the stirring oil was discussed. The minimum oil film thickness was required for the life of the gearbox. The accuracy of the calculation results was verified by the transmission efficiency test conducted on the two-motor integrated test bench. The results show that the efficiency increases first and then decreases with the increase of the speed and decreases with the increase of the kinematic viscosity of the lubricant. The increase of the kinematic viscosity amplifies the transmission power loss caused by the high speed. New energy vehicle special lubricants have less attenuation of transmission efficiency in the range above mid-speed. The research results provide a theoretical basis and guidance for the evaluation and selection of transmission efficiency of gearbox lubricants for new energy vehicles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=new%20energy%20vehicles" title="new energy vehicles">new energy vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=lubricants" title=" lubricants"> lubricants</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20efficiency" title=" transmission efficiency"> transmission efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=kinematic%20viscosity" title=" kinematic viscosity"> kinematic viscosity</a>, <a href="https://publications.waset.org/abstracts/search?q=test%20and%20simulation" title=" test and simulation"> test and simulation</a> </p> <a href="https://publications.waset.org/abstracts/128894/analysis-and-experimental-research-on-the-influence-of-lubricating-oil-on-the-transmission-efficiency-of-new-energy-vehicle-gearbox" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128894.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">80</span> Using Predictive Analytics to Identify First-Year Engineering Students at Risk of Failing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beng%20Yew%20Low">Beng Yew Low</a>, <a href="https://publications.waset.org/abstracts/search?q=Cher%20Liang%20Cha"> Cher Liang Cha</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheng%20Yong%20Teoh"> Cheng Yong Teoh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to a lack of continual assessment or grade related data, identifying first-year engineering students in a polytechnic education at risk of failing is challenging. Our experience over the years tells us that there is no strong correlation between having good entry grades in Mathematics and the Sciences and excelling in hardcore engineering subjects. Hence, identifying students at risk of failure cannot be on the basis of entry grades in Mathematics and the Sciences alone. These factors compound the difficulty of early identification and intervention. This paper describes the development of a predictive analytics model in the early detection of students at risk of failing and evaluates its effectiveness. Data from continual assessments conducted in term one, supplemented by data of student psychological profiles such as interests and study habits, were used. Three classification techniques, namely Logistic Regression, K Nearest Neighbour, and Random Forest, were used in our predictive model. Based on our findings, Random Forest was determined to be the strongest predictor with an Area Under the Curve (AUC) value of 0.994. Correspondingly, the Accuracy, Precision, Recall, and F-Score were also highest among these three classifiers. Using this Random Forest Classification technique, students at risk of failure could be identified at the end of term one. They could then be assigned to a Learning Support Programme at the beginning of term two. This paper gathers the results of our findings. It also proposes further improvements that can be made to the model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=continual%20assessment"
