Unlike the typical biodiesel production plants, mobile biodiesel unit consiss of a biodiesel production facility placed inside a standard cargo container and mounted on a truck so that it can be transported to a region near the location of raw materials. In this paper, we review the existing concept and unit for the development of community-scale and mobile production of biodiesel. This includes the main reactor technology to produce biodiesel as well as the pre-treatment prior to the reaction unit. The pre-treatment includes the oil-expeller unit to obtain oil from the oilseeds as well as the quality control of the oil before it enters the reaction unit. This paper also discusses the post-treatment after the production of biodiesel. It includes the refining and purification of biodiesel to meet the product specification set by the biodiesel industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiesel" title="biodiesel">biodiesel</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20scale" title=" community scale"> community scale</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20biodiesel%20unit" title=" mobile biodiesel unit"> mobile biodiesel unit</a>, <a href="https://publications.waset.org/abstracts/search?q=reactor%20technology" title=" reactor technology"> reactor technology</a> </p> <a href="https://publications.waset.org/abstracts/85377/small-scale-stationary-and-mobile-production-of-biodiesel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85377.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">236</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">317</span> Parental Monitoring of Learners’ Cell Phone Use in the Eastern Cape, South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Melikhaya%20Skhephe">Melikhaya Skhephe</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Mawuli%20Kwasi%20Boadzo"> Robert Mawuli Kwasi Boadzo</a>, <a href="https://publications.waset.org/abstracts/search?q=Zanoxolo%20Berington%20Gobingca"> Zanoxolo Berington Gobingca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research study sought to examine parental monitoring of learners’ cell phone use in the Eastern Cape, South Africa. To this end, the researchers employed a quantitative approach. Data were obtained through questionnaires, with a sample of 15 parents having been purposively selected. The findings revealed that parents are unaware that they have to monitor the learner’s cell phone. Another finding was that parents in the 21-century did not support the use of mobile phones in education. The researchers recommend that parent’s discussion forums be created to educate parents on how a cell phone can be used in education. Cellphone companies need to be encouraged to educate parents on how they monitor cell phones used by learners. Another recommendation was that network providers need to restrict access to searching on the internet according to age. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parental%20monitoring" title="parental monitoring">parental monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=app%20blocking%20services" title=" app blocking services"> app blocking services</a>, <a href="https://publications.waset.org/abstracts/search?q=learner%E2%80%99s%20cell%20phone%20use" title=" learner’s cell phone use"> learner’s cell phone use</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20phone" title=" cell phone"> cell phone</a> </p> <a href="https://publications.waset.org/abstracts/130742/parental-monitoring-of-learners-cell-phone-use-in-the-eastern-cape-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130742.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">159</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">316</span> A False Introduction: Teaching in a Pandemic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robert%20Michael">Robert Michael</a>, <a href="https://publications.waset.org/abstracts/search?q=Kayla%20Tobin"> Kayla Tobin</a>, <a href="https://publications.waset.org/abstracts/search?q=William%20Foster"> William Foster</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachel%20Fairchild"> Rachel Fairchild</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The COVID-19 pandemic has caused significant disruptions in education, particularly in the teaching of health and physical education (HPE). This study examined a cohort of teachers that experienced being a preservice and first-year teacher during various stages of the pandemic. Qualitative data collection was conducted by interviewing six teachers from different schools in the Eastern U.S. over a series of structured interviews. Thematic analysis was employed to analyze the data. The pandemic significantly impacted the way HPE was taught as schools shifted to virtual and hybrid models. Findings revealed five major themes: (a) You want me to teach HOW?, (b) PE without equipment and six feet apart, (c) Behind the Scenes, (d) They’re back…I became a behavior management guru, and (e) The Pandemic Crater. Overall, this study highlights the significant challenges faced by preservice and first-year teachers in teaching physical education during the pandemic and underscores the need for ongoing support and resources to help them adapt and succeed in these challenging circumstances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=teacher%20education" title="teacher education">teacher education</a>, <a href="https://publications.waset.org/abstracts/search?q=preservice%20teachers" title=" preservice teachers"> preservice teachers</a>, <a href="https://publications.waset.org/abstracts/search?q=first%20year%20teachers" title=" first year teachers"> first year teachers</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20and%20physical%20education" title=" health and physical education"> health and physical education</a> </p> <a href="https://publications.waset.org/abstracts/171529/a-false-introduction-teaching-in-a-pandemic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171529.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">185</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">315</span> A Deep Learning Based Integrated Model For Spatial Flood Prediction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vinayaka%20Gude%20Divya%20Sampath">Vinayaka Gude Divya Sampath</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research introduces an integrated prediction model to assess the susceptibility of roads in a future flooding event. The model consists of deep learning algorithm for forecasting gauge height data and Flood Inundation Mapper (FIM) for spatial flooding. An optimal architecture for Long short-term memory network (LSTM) was identified for the gauge located on Tangipahoa River at Robert, LA. Dropout was applied to the model to evaluate the uncertainty associated with the predictions. The estimates are then used along with FIM to identify the spatial flooding. Further geoprocessing in ArcGIS provides the susceptibility values for different roads. The model was validated based on the devastating flood of August 2016. The paper discusses the challenges for generalization the methodology for other locations and also for various types of flooding. The developed model can be used by the transportation department and other emergency response organizations for effective disaster management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title="deep learning">deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=disaster%20management" title=" disaster management"> disaster management</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20prediction" title=" flood prediction"> flood prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20flooding" title=" urban flooding"> urban flooding</a> </p> <a href="https://publications.waset.org/abstracts/129566/a-deep-learning-based-integrated-model-for-spatial-flood-prediction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129566.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">146</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">314</span> Gamification to Enhance Learning Using Gagne's Learning Model </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20L.%20McLain">M.

In this study we explore a novel way to improve how high school students learn by building a serious game that uses a pedagogical model developed by Robert Gagne. By integrating serious game with principles of Gagne’s learning model can provide engaging and meaningful instructions to students. The game developed in this study is a waste sorting game that can easily and succinctly demonstrate the principles of this learning model. All the tasks in the game that the player has to accomplish correspond to Gagne’s “Nine Events of Learning”. A quiz is incorporated in order to get data on the progress made by the player in understanding the concept and as well as to assess them. Additionally, an experimental study was conducted which demonstrates that game based learning using Gagne’s event is more effective than a traditional classroom setup. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=game%20based%20learning" title="game based learning">game based learning</a>, <a href="https://publications.waset.org/abstracts/search?q=sorting%20and%20recycling%20of%20waste" title=" sorting and recycling of waste"> sorting and recycling of waste</a>, <a href="https://publications.waset.org/abstracts/search?q=Gagne%E2%80%99s%20learning%20model" title=" Gagne’s learning model"> Gagne’s learning model</a>, <a href="https://publications.waset.org/abstracts/search?q=e-Learning" title=" e-Learning"> e-Learning</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20enhanced%20learning" title=" technology enhanced learning"> technology enhanced learning</a> </p> <a href="https://publications.waset.org/abstracts/31477/gamification-to-enhance-learning-using-gagnes-learning-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31477.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">631</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">313</span> Analysis of the Temperature Dependence of Local Avalanche Compact Model for Bipolar Transistors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robert%20Setekera">Robert Setekera</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramses%20van%20der%20Toorn"> Ramses van der Toorn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present an extensive analysis of the temperature dependence of the local avalanche model used in most of the modern compact models for bipolar transistors. This local avalanche model uses the Chynoweth's empirical law for ionization coefficient to define the generation of the avalanche current in terms of the local electric field. We carry out the model analysis using DC-measurements taken on both Si and advanced SiGe bipolar transistors. For the advanced industrial SiGe-HBTs, we consider both high-speed and high-power devices (both NPN and PNP transistors). The limitations of the local avalanche model in modeling the temperature dependence of the avalanche current mostly in the weak avalanche region are demonstrated. In addition, the model avalanche parameters are analyzed to see if they are in agreement with semiconductor device physics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=avalanche%20multiplication" title="avalanche multiplication">avalanche multiplication</a>, <a href="https://publications.waset.org/abstracts/search?q=avalanche%20current" title=" avalanche current"> avalanche current</a>, <a href="https://publications.waset.org/abstracts/search?q=bipolar%20transistors" title=" bipolar transistors"> bipolar transistors</a>, <a href="https://publications.waset.org/abstracts/search?q=compact%20modeling" title=" compact modeling"> compact modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20field" title=" electric field"> electric field</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20ionization" title=" impact ionization"> impact ionization</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20avalanche" title=" local avalanche"> local avalanche</a> </p> <a href="https://publications.waset.org/abstracts/15421/analysis-of-the-temperature-dependence-of-local-avalanche-compact-model-for-bipolar-transistors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15421.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">622</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">312</span> The Optimisation of Salt Impregnated Matrices as Potential Thermochemical Storage Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robert%20J.%20Sutton">Robert J.

Highly porous vermiculite impregnated with CaCl2, LiNO3 and MgSO4 (SIMs – Salt In Matrices) are proposed as potential materials for long-term thermochemical storage. The behavior of these materials during typical hydration and dehydration cycles is investigated. A simple moisture experiment represents the hydration, whilst thermogravimetric analysis (TGA) represents the dehydration. Further experiments to approximate the energy density and to determine the peak output temperatures of the SIMs are conducted. The CaCl2 SIM is deemed the best performing SIM across most experiments, whilst the results of MgSO4 SIM indicate difficulty associated with energy recovery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrated%20states" title="hydrated states">hydrated states</a>, <a href="https://publications.waset.org/abstracts/search?q=inter-seasonal%20heat%20storage" title=" inter-seasonal heat storage"> inter-seasonal heat storage</a>, <a href="https://publications.waset.org/abstracts/search?q=moisture%20sorption" title=" moisture sorption"> moisture sorption</a>, <a href="https://publications.waset.org/abstracts/search?q=salt%20in%20matrix" title=" salt in matrix"> salt in matrix</a> </p> <a href="https://publications.waset.org/abstracts/28423/the-optimisation-of-salt-impregnated-matrices-as-potential-thermochemical-storage-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28423.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">554</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">311</span> Distance Education: Using a Digital Platform to Improve Struggling University Students' Mathematical Skills</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robert%20Vanderburg">Robert Vanderburg</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Gibson"> Nicholas Gibson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: There has been an increased focus in education students’ mathematics skills in the last two years. Universities have, specifically, had problems teaching students struggling with mathematics. This paper focuses on the ability of a digital platform to significantly improve mathematics skills for struggling students. Methods: 32 students who demonstrated low scores on a mathematics test were selected to take part in a one-month tutorial program using a digital mathematics portal. Students were provided feedback for questions posted on the portal and a fortnightly tutorial session. Results: A pre-test post-test design was analyzed using a one-way analysis of variance (ANOVA). The analysis suggested that students improved skills in algebra, geometry, statistics, probability, ratios, fractions, and probability. Conclusion: Distance university students can improve their mathematics skills using a digital platform. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20education" title="digital education">digital education</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20education" title=" distance education"> distance education</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education"> higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematics%20education" title=" mathematics education"> mathematics education</a> </p> <a href="https://publications.waset.org/abstracts/101959/distance-education-using-a-digital-platform-to-improve-struggling-university-students-mathematical-skills" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101959.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">185</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">310</span> Characterizing Compressive Strength of Compressed Stabilized Earth Blocks as a Function of Mix Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robert%20K.%20Hillyard">Robert K.

These CSEB’s offer a cost-effective building solution for remote construction, using local resources and labor to minimize transportation and material costs. However, CSEB’s, and earthen construction generally have not been widely adopted as standardized construction materials. One shortcoming is the difficulty in standardizing strength values of CSEB units and systems due to the inherent variations in mix design, including production compression. This research presents findings on compressive strengths of full-scale CSEB’s from 60 different mix designs as a function of the amount of cement, sand, soil, and water added to the mixture. The full-scale results are compared with CSEB cylinder cores. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CSEB" title="CSEB">CSEB</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=earth%20construction" title=" earth construction"> earth construction</a>, <a href="https://publications.waset.org/abstracts/search?q=mix%20design" title=" mix design"> mix design</a> </p> <a href="https://publications.waset.org/abstracts/153165/characterizing-compressive-strength-of-compressed-stabilized-earth-blocks-as-a-function-of-mix-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153165.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">99</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">309</span> Portable Hands-Free Process Assistant for Gas Turbine Maintenance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Brandenburg">Elisabeth Brandenburg</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Woll"> Robert Woll</a>, <a href="https://publications.waset.org/abstracts/search?q=Rainer%20Stark"> Rainer Stark</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents how smart glasses and voice commands can be used for improving the maintenance process of industrial gas turbines.

In the following, it will be presented how the approach of user-centered design and the method of paper prototyping have been successfully applied in order to design a user interface and a corresponding workflow model that describes the possible interaction patterns between the user and the interface.

A low-power Ku-band radar system was developed to demonstrate these advantages. It is fully coherent, and it interleaves short and long pulses to achieve a transmit duty ratio of 25%, which makes the best use of solid-state amplifiers. The range scales are 2 km, 4 km, and 8 km. The minimum range is 100 m, 200 m, and 400 m for the three range scales, and the range resolution is 4 m, 8 m, and 16 m for the three range scales. Measurements of the significant wave height, wavelength, wave period, and wave direction have been made using traditional 3D-FFT methods.

Accurate modelling of manipulation requires identification of forces and mechanical knowledge in the Nanoscale which are different from macro world. Due to the importance of the adhesion forces and the interaction of surfaces at the nanoscale several friction models were presented. In this research, friction and normal forces that are applied on the AFM by using of the dynamic bending-torsion model of AFM are obtained based on Hurtado-Kim friction model (HK), Johnson-Kendall-Robert contact model (JKR) and Greenwood-Williamson roughness model (GW). Finally, the effect of standard deviation of asperities height on the normal load, friction force and friction coefficient are studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atomic%20force%20microscopy" title="atomic force microscopy">atomic force microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=contact%20model" title=" contact model"> contact model</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20coefficient" title=" friction coefficient"> friction coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=Greenwood-Williamson%20model" title=" Greenwood-Williamson model"> Greenwood-Williamson model</a> </p> <a href="https://publications.waset.org/abstracts/85332/modelling-of-atomic-force-microscopic-nano-robots-friction-force-on-rough-surfaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85332.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">199</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">306</span> Use of Opti-Jet Cs Md1mr Device for Biocide Aerosolisation in 3t Magnetic Resonance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robert%20Pintaric">Robert Pintaric</a>, <a href="https://publications.waset.org/abstracts/search?q=Joze%20Matela"> Joze Matela</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefan%20Pintaric"> Stefan Pintaric</a>, <a href="https://publications.waset.org/abstracts/search?q=Stanka%20Vadnjal"> Stanka Vadnjal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: This work is aimed to represent the use of the OPTI-JET CS MD1 MR prototype for application of neutral electrolyzed oxidizing water (NEOW) in magnetic resonance rooms. Material and Methods: We produced and used OPTI-JET CS MD1 MR aerosolisator whereby was performed aerosolization. The presence of microorganisms before and after the aerosolisation was recorded with the help of cyclone air sampling. Colony formed units (CFU) was counted. Results: The number of microorganisms in magnetic resonance 3T room was low as expected. Nevertheless, a possible CFU reduction of 87% was recorded. Conclusions: The research has shown that the use of EOW for the air and hard surface disinfection can considerably reduce the presence of microorganisms and consequently the possibility of hospital infections. It has also demonstrated that the use of OPTI-JET CS MD1 MR is very good. With this research, we started new guidelines for aerosolization in magnetic resonance rooms. Future work: We predict that presented technique works very good but we must focus also on time capacity sensors, and new appropriate toxicological studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biocide" title="biocide">biocide</a>, <a href="https://publications.waset.org/abstracts/search?q=electrolyzed%20oxidizing%20water%20%28EOW%29" title=" electrolyzed oxidizing water (EOW)"> electrolyzed oxidizing water (EOW)</a>, <a href="https://publications.waset.org/abstracts/search?q=disinfection" title=" disinfection"> disinfection</a>, <a href="https://publications.waset.org/abstracts/search?q=microorganisms" title=" microorganisms"> microorganisms</a>, <a href="https://publications.waset.org/abstracts/search?q=OPTI-JET%20CS%20MD1MR" title=" OPTI-JET CS MD1MR"> OPTI-JET CS MD1MR</a> </p> <a href="https://publications.waset.org/abstracts/35512/use-of-opti-jet-cs-md1mr-device-for-biocide-aerosolisation-in-3t-magnetic-resonance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35512.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">391</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">305</span> Ready Student One!

It starts with an idea, but that needs to be coupled with the right team of experts willing to take big risks and put in the hard work to build something different. An instructional design team was empowered to reimagine an Introduction to Sociology university course as a Game-Based Learning (GBL) experience utilizing cutting edge Virtual Reality (VR) technology. The result was a collaborative process that resulted in a type of learning based in Game theory, Method of Loci, and VR Immersion Simulations to promote deeper retention of core concepts. The team deconstructed the way that university courses operated, in order to rebuild the educational process in a whole learner-centric manner. In addition to a review of the build process, this paper will explore the results of in-course surveys completed by student participants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title="higher education">higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20reality" title=" virtual reality"> virtual reality</a>, <a href="https://publications.waset.org/abstracts/search?q=game-based%20learning" title=" game-based learning"> game-based learning</a>, <a href="https://publications.waset.org/abstracts/search?q=loci%20method" title=" loci method"> loci method</a> </p> <a href="https://publications.waset.org/abstracts/168452/ready-student-one-exploring-how-to-build-a-successful-game-based-higher-education-course-in-virtual-reality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168452.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">95</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">304</span> Rumination in Borderline Personality Disorder: A Meta-Analytic Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mara%20J.%20Richman">Mara J.

Of this domain, ruminative behaviors have been considered a core feature of emotion dysregulation difficulties. Taking this into consideration, a meta-analysis was performed to assess how BPD symptoms correlate with rumination, while also considering clinical moderator variables such as comorbidity, GAF score, and type of BPD symptom and demographic moderator variables such as age, gender, and education level. Analysis of correlation across rumination domains for the entire sample revealed a medium overall correlation. When assessing types of rumination, the largest correlation was among pain rumination followed by anger, depressive, and anxious rumination. Furthermore, affective instability had the strongest correlation with increased rumination, followed by unstable relationships, identity disturbance, and self-harm/ impulsivity, respectively. Demographic variables showed no significance. Clinical implications are considered and further therapeutic interventions are discussed in the context of rumination. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=borderline%20personality%20disorder" title="borderline personality disorder">borderline personality disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-analysis" title=" meta-analysis"> meta-analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=rumination" title=" rumination"> rumination</a>, <a href="https://publications.waset.org/abstracts/search?q=symptoms" title=" symptoms"> symptoms</a> </p> <a href="https://publications.waset.org/abstracts/88367/rumination-in-borderline-personality-disorder-a-meta-analytic-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88367.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">194</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">303</span> Non-Interactive XOR Quantum Oblivious Transfer: Optimal Protocols and Their Experimental Implementations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lara%20Stroh">Lara Stroh</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikola%20Horov%C3%A1"> Nikola Horová</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20St%C3%A1rek"> Robert Stárek</a>, <a href="https://publications.waset.org/abstracts/search?q=Ittoop%20V.%20Puthoor"> Ittoop V.

Any multi-party computation can be realised with OT as a building block. XOR oblivious transfer (XOT) is a variant where the sender Alice has two bits, and a receiver, Bob, obtains either the first bit, the second bit, or their XOR. Bob should not learn anything more than this, and Alice should not learn what Bob has learned. Perfect quantum OT with information-theoretic security is known to be impossible. We determine the smallest possible cheating probabilities for unrestricted dishonest parties in non-interactive quantum XOT protocols using symmetric pure states and present an optimal protocol which outperforms classical protocols. We also "reverse" this protocol so that Bob becomes the sender of a quantum state and Alice the receiver who measures it while still implementing oblivious transfer from Alice to Bob. Cheating probabilities for both parties stay the same as for the unreversed protocol. We optically implemented both the unreversed and the reversed protocols and cheating strategies, noting that the reversed protocol is easier to implement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oblivious%20transfer" title="oblivious transfer">oblivious transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20protocol" title=" quantum protocol"> quantum protocol</a>, <a href="https://publications.waset.org/abstracts/search?q=cryptography" title=" cryptography"> cryptography</a>, <a href="https://publications.waset.org/abstracts/search?q=XOR" title=" XOR"> XOR</a> </p> <a href="https://publications.waset.org/abstracts/168274/non-interactive-xor-quantum-oblivious-transfer-optimal-protocols-and-their-experimental-implementations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168274.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">126</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">302</span> The First Transcriptome Assembly of Marama Bean: An African Orphan Crop</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ethel%20E.%20Phiri">Ethel E.

They have been documented to have the ability to tolerate extreme environmental conditions. However, limited research has been conducted to uncover their potential as food crop species. The New Partnership for Africa’s Development (NEPAD) has classified Marama bean, Tylosema esculentum, as an orphan crop. The plant is one of the 101 African orphan crops that must have their genomes sequenced, assembled, and annotated in the foreseeable future. Marama bean is a perennial leguminous plant that primarily grows in poor, arid soils in southern Africa. The plants produce large tubers that can weigh as much as 200kg. While the foliage provides fodder, the tuber is carbohydrate rich and is a staple food source for rural communities in Namibia. Also, the edible seeds are protein- and oil-rich. Marama Bean plants respond rapidly to increased temperatures and severe water scarcity without extreme consequences. Advances in molecular biology and biotechnology have made it possible to effectively transfer technologies between model- and major crops to orphan crops. In this research, the aim was to assemble the first transcriptomic analysis of Marama Bean RNA-sequence data. Many model plant species have had their genomes sequenced and their transcriptomes assembled. Therefore the availability of transcriptome data for a non-model crop plant species will allow for gene identification and comparisons between various species. The data has been sequenced using the Ilumina Hiseq 2500 sequencing platform. Data analysis is underway. In essence, this research will eventually evaluate the potential use of Marama Bean as a crop species to improve its value in agronomy. data for a non-model crop plant species will allow for gene identification and comparisons between various species.

With the widespread use of modern methods of disrupting communication between users, real use-cases of advanced encryption mechanisms have emerged to avoid cyber-attackers that are willing to intercept private conversations between critical employees in an organization. This paper aims to present a custom implementation of a messaging application named “Whisper” that uses end-to-end encryption (E2EE) mechanisms and blockchain-related components to protect sensitive conversations and mitigate the risks of information breaches inside organizations. The results of this research paper aim to expand the areas of applicability of E2EE algorithms and integrations with private blockchains in chat applications as a viable method of enhancing intra-organizational communication privacy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=end-to-end%20encryption" title="end-to-end encryption">end-to-end encryption</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20communication" title=" mobile communication"> mobile communication</a>, <a href="https://publications.waset.org/abstracts/search?q=cryptography" title=" cryptography"> cryptography</a>, <a href="https://publications.waset.org/abstracts/search?q=communication%20security" title=" communication security"> communication security</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20privacy" title=" data privacy"> data privacy</a> </p> <a href="https://publications.waset.org/abstracts/168928/using-a-blockchain-based-end-to-end-encrypted-communication-system-between-mobile-terminals-to-improve-organizational-privacy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168928.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">89</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">300</span> Low-Noise Amplifier Design for Improvement of Communication Range for Wake-Up Receiver Based Wireless Sensor Network Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ilef%20Ketata">Ilef Ketata</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Khalil%20Baazaoui"> Mohamed Khalil Baazaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Fromm"> Robert Fromm</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Fakhfakh"> Ahmad Fakhfakh</a>, <a href="https://publications.waset.org/abstracts/search?q=Faouzi%20Derbel"> Faouzi Derbel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The integration of wireless communication, e. g. in real-or quasi-real-time applications, is related to many challenges such as energy consumption, communication range, latency, quality of service, and reliability. To minimize the latency without increasing energy consumption, wake-up receiver (WuRx) nodes have been introduced in recent works. Low-noise amplifiers (LNAs) are introduced to improve the WuRx sensitivity but increase the supply current severely. Different WuRx approaches exist with always-on, power-gated, or duty-cycled receiver designs. This paper presents a comparative study for improving communication range and decreasing the energy consumption of wireless sensor nodes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20network" title="wireless sensor network">wireless sensor network</a>, <a href="https://publications.waset.org/abstracts/search?q=wake-up%20receiver" title=" wake-up receiver"> wake-up receiver</a>, <a href="https://publications.waset.org/abstracts/search?q=duty-cycled" title=" duty-cycled"> duty-cycled</a>, <a href="https://publications.waset.org/abstracts/search?q=low-noise%20amplifier" title=" low-noise amplifier"> low-noise amplifier</a>, <a href="https://publications.waset.org/abstracts/search?q=envelope%20detector" title=" envelope detector"> envelope detector</a>, <a href="https://publications.waset.org/abstracts/search?q=range%20study" title=" range study"> range study</a> </p> <a href="https://publications.waset.org/abstracts/156750/low-noise-amplifier-design-for-improvement-of-communication-range-for-wake-up-receiver-based-wireless-sensor-network-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156750.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">112</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">299</span> Rotor Radial Vent Pumping in Large Synchronous Electrical Machines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Darren%20Camilleri">Darren Camilleri</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Rolston"> Robert Rolston</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rotor radial vents make use of the pumping effect to increase airflow through the active material thus reduce hotspot temperatures. The effect of rotor radial pumping in synchronous machines has been studied previously. This paper presents the findings of previous studies and builds upon their theories using a parametric numerical approach to investigate the rotor radial pumping effect. The pressure head generated by the poles and radial vent flow-rate were identified as important factors in maximizing the benefits of the pumping effect. The use of Minitab and ANSYS Workbench to investigate the key performance characteristics of radial pumping through a Design of Experiments (DOE) was described. CFD results were compared with theoretical calculations. A correlation for each response variable was derived through a statistical analysis. Findings confirmed the strong dependence of radial vent length on vent pressure head, and radial vent cross-sectional area was proved to be significant in maximising radial vent flow rate. <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=cooling" title=" cooling"> cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20machines" title=" electrical machines"> electrical machines</a>, <a href="https://publications.waset.org/abstracts/search?q=regression%20analysis" title=" regression analysis"> regression analysis</a> </p> <a href="https://publications.waset.org/abstracts/41880/rotor-radial-vent-pumping-in-large-synchronous-electrical-machines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41880.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">312</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">298</span> A Mixed Approach to Assess Information System Risk, Operational Risk, and Congolese Microfinance Institutions Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alfred%20Kamate%20Siviri">Alfred Kamate Siviri</a>, <a href="https://publications.waset.org/abstracts/search?q=Angelus%20Mafikiri%20Tsongo"> Angelus Mafikiri Tsongo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean%20Robert%20Kala%20Kamdjoug"> Jean Robert Kala Kamdjoug</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Digitalization and information systems well organized have been selected as relevant measures to mitigate operational risks within organizations.

This study aims to measure perceived information system risks and their effects on operational risks within the microfinance institution in D.R. Congo. Also, the factors influencing the operational risk are identified, and the link between operational risk with other risks and performance is to be assessed. The study proposes a research model drawn on the combination of Resources-Based-View, dynamic capabilities, the agency theory, the Information System Security Model, and social theories of risk. Therefore, we suggest adopting a mixed methods research with the sole aim of increasing the literature that already exists on perceived operational risk assessment and its link with other risk and performance, a focus on IT risk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Democratic%20Republic%20Congo" title="Democratic Republic Congo">Democratic Republic Congo</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20system%20risk" title=" information system risk"> information system risk</a>, <a href="https://publications.waset.org/abstracts/search?q=microfinance%20performance" title=" microfinance performance"> microfinance performance</a>, <a href="https://publications.waset.org/abstracts/search?q=operational%20risk" title=" operational risk"> operational risk</a> </p> <a href="https://publications.waset.org/abstracts/138708/a-mixed-approach-to-assess-information-system-risk-operational-risk-and-congolese-microfinance-institutions-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138708.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">224</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">297</span> Estimation of the Upper Tail Dependence Coefficient for Insurance Loss Data Using an Empirical Copula-Based Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adrian%20O%27Hagan">Adrian O'Hagan</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20McLoughlin"> Robert McLoughlin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Considerable focus in the world of insurance risk quantification is placed on modeling loss values from lines of business (LOBs) that possess upper tail dependence. Copulas such as the Joe, Gumbel and Student-t copula may be used for this purpose. The copula structure imparts a desired level of tail dependence on the joint distribution of claims from the different LOBs. Alternatively, practitioners may possess historical or simulated data that already exhibit upper tail dependence, through the impact of catastrophe events such as hurricanes or earthquakes. In these circumstances, it is not desirable to induce additional upper tail dependence when modeling the joint distribution of the loss values from the individual LOBs. Instead, it is of interest to accurately assess the degree of tail dependence already present in the data. The empirical copula and its associated upper tail dependence coefficient are presented in this paper as robust, efficient means of achieving this goal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=empirical%20copula" title="empirical copula">empirical copula</a>, <a href="https://publications.waset.org/abstracts/search?q=extreme%20events" title=" extreme events"> extreme events</a>, <a href="https://publications.waset.org/abstracts/search?q=insurance%20loss%20reserving" title=" insurance loss reserving"> insurance loss reserving</a>, <a href="https://publications.waset.org/abstracts/search?q=upper%20tail%20dependence%20coefficient" title=" upper tail dependence coefficient"> upper tail dependence coefficient</a> </p> <a href="https://publications.waset.org/abstracts/2645/estimation-of-the-upper-tail-dependence-coefficient-for-insurance-loss-data-using-an-empirical-copula-based-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2645.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">284</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">296</span> Iterative Design Process for Development and Virtual Commissioning of Plant Control Software</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thorsten%20Prante">Thorsten Prante</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Sch%C3%B6ch"> Robert Schöch</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruth%20Fleisch"> Ruth Fleisch</a>, <a href="https://publications.waset.org/abstracts/search?q=Vaheh%20Khachatouri"> Vaheh Khachatouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Walch"> Alexander Walch</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of industrial plant control software is a complex and often very expensive task. One of the core problems is that a lot of the implementation and adaptation work can only be done after the plant hardware has been installed. In this paper, we present our approach to virtually developing and validating plant-level control software of production plants. This way, plant control software can be virtually commissioned before actual ramp-up of a plant, reducing actual commissioning costs and time. Technically, this is achieved by linking the actual plant-wide process control software (often called plant server) and an elaborate virtual plant model together to form an emulation system. Method-wise, we are suggesting a four-step iterative process with well-defined increments and time frame. Our work is based on practical experiences from planning to commissioning and start-up of several cut-to-size plants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iterative%20system%20design" title="iterative system design">iterative system design</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20plant%20engineering" title=" virtual plant engineering"> virtual plant engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20control%20software" title=" plant control software"> plant control software</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation%20and%20emulation" title=" simulation and emulation"> simulation and emulation</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20commissioning" title=" virtual commissioning"> virtual commissioning</a> </p> <a href="https://publications.waset.org/abstracts/14534/iterative-design-process-for-development-and-virtual-commissioning-of-plant-control-software" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14534.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">488</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">295</span> The Intersection of Masculinity and Disability in the Spatial Experience of Visually Impaired Men</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lucie%20Posp%C3%AD%C5%A1ilov%C3%A1">Lucie Pospíšilová</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Osman"> Robert Osman</a>, <a href="https://publications.waset.org/abstracts/search?q=Hana%20Porkertov%C3%A1"> Hana Porkertová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The scholarly literature demonstrates disability and masculinity in conflict with each other. While disability is associated with dependence, weakness, or helplessness, masculinity is associated with independence, strength, and power. Thus, disabled masculinity might be a dilemma experienced on a personal level. The relationship between masculinity and disability is also interesting from a geographical point of view because the conception of space is gendered. In our society, the skills like spatial orientation, working with the maps, and navigation technologies as same as with scale are associated with masculinity. And because these skills are related to the visual imagination, it is the blindness that is associated with the limitation or even the absence of them. Thus, the conflict of masculinity and disability in the spatial experience is very well apparent in the case of visually impaired men. To study this conflict can tell us a lot not only about the experience of visually impaired men but also about the conception of space in geography and in our society. The paper uses Henri Lefebvre's theory of space based on a triad of spatial practice, representations of space, and representational space. It answers the question: How masculinity and disability intersect in the spatial experience of visually impaired men? The data come from research conducted in Brno and Prague (Czechia) in 2020 and 2021 and include 7 interviews and 6 go-alongs with visually impaired men. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disability" title="disability">disability</a>, <a href="https://publications.waset.org/abstracts/search?q=masculinity" title=" masculinity"> masculinity</a>, <a href="https://publications.waset.org/abstracts/search?q=abstract%20space" title=" abstract space"> abstract space</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20experience" title=" spatial experience"> spatial experience</a>, <a href="https://publications.waset.org/abstracts/search?q=visually%20impaired%20men" title=" visually impaired men"> visually impaired men</a> </p> <a href="https://publications.waset.org/abstracts/147743/the-intersection-of-masculinity-and-disability-in-the-spatial-experience-of-visually-impaired-men" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147743.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">165</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">294</span> Optical Properties of a One Dimensional Graded Photonic Structure Based on Material Length Redistribution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Danny%20Manuel%20Calvo%20Velasco">Danny Manuel Calvo Velasco</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Sanchez%20Cano"> Robert Sanchez Cano</a> </p> <p class="card-text"><strong>Abstract:</strong></p> By using the transference matrix formalism, in this work, it is presented the study of the optical properties of the 1D graded structure, constructed by multiple bi-layers of dielectric and air, considering a redistribution of the material lengths following an arithmetic progression as a function of two parameters. It is presented a factorization for the transference matrices for the graded structure, which allows the interpretation of their optical properties in terms of the properties of simpler structures. It is shown that the graded structure presents new transmission peaks, which can be controlled by the parameter values located in frequencies for which a periodic system has a photonic bandgap. This result is extended to the case of a photonic crystal for which the unitary cell is the proposed graded structure, showing new transmission bands which are due to the multiple new sub-structures present in the system. Also, for the TE polarization, it is observed transmission bands' low frequencies which present low variation of its width and position with the incidence angle. It is expected that these results could guide a route in the design of new photonic devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graded" title="graded">graded</a>, <a href="https://publications.waset.org/abstracts/search?q=material%20redistribution" title=" material redistribution"> material redistribution</a>, <a href="https://publications.waset.org/abstracts/search?q=photonic%20system" title=" photonic system"> photonic system</a>, <a href="https://publications.waset.org/abstracts/search?q=transference%20matrix" title=" transference matrix"> transference matrix</a> </p> <a href="https://publications.waset.org/abstracts/137354/optical-properties-of-a-one-dimensional-graded-photonic-structure-based-on-material-length-redistribution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137354.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">293</span> The SOCI Strategy as a Method to Meet the Innovation Challenges of COVID-19</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victoria%20Wolf">Victoria Wolf</a>, <a href="https://publications.waset.org/abstracts/search?q=Renata%20Dobrucka"> Renata Dobrucka</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Prezkop"> Robert Prezkop</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20Haubold"> Stephan Haubold</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The COVID-19 causes a worldwide crisis and has an impact in every dimension of the economy. Organizations with the ability to adapt to new developments and which innovate solutions for the disrupted world during and after the Corona crises have the opportunity to not only survive the crisis but rather to use new trends to implement new business models and gain advantage. In this context, startups seem to have better opportunities to manage the Corona crisis through their innovation-based nature. The main result of this paper is the understanding that by applying a startup orientated innovation (SOCI) strategy, established companies can be motivated to meet the challenge of COVID-19 in a similar way like startups. This result can be achieved by describing the role of innovation and a SOCI strategy as helpful methods for organizations to meet the coming challenges during and after the COVID-19 epidemics. In addition to this, this paper presents a practical application of SOCI through the PANDA approach of the Fresenius University of Applied Sciences in Germany and discuss it in the context of COVID-19 as an exemplary successful real-world implementation of SOCI strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Covid-19" title="Covid-19">Covid-19</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20innovation" title=" open innovation"> open innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=startup" title=" startup"> startup</a>, <a href="https://publications.waset.org/abstracts/search?q=soci%20framework" title=" soci framework"> soci framework</a> </p> <a href="https://publications.waset.org/abstracts/134180/the-soci-strategy-as-a-method-to-meet-the-innovation-challenges-of-covid-19" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134180.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">235</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">292</span> The Impact of Corn Grain Consolidation on the Emission of Volatile Organic Compounds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marek%20Gancarz">Marek Gancarz</a>, <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Gr%C4%85decka-Jakubowska"> Katarzyna Grądecka-Jakubowska</a>, <a href="https://publications.waset.org/abstracts/search?q=Urszula%20Malaga-Tobo%C5%82a"> Urszula Malaga-Toboła</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafa%C5%82%20Kornas"> Rafał Kornas</a>, <a href="https://publications.waset.org/abstracts/search?q=Aleksandra%20%C5%BBytek"> Aleksandra Żytek</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Rusinek"> Robert Rusinek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the research was to determine the emission of volatile organic compounds (VOCs) from corn grain depending on the degree of consolidation of the bulk material, imitating the processes occurring in silos during material storage. An electronic nose and a gas chromatograph were used for VOC analysis. Corn grain was densified under pressure of 40 and 80 kPa. Control samples of corn grain were not compacted and had bulk density. The analyzes were carried out at 14% and 17% humidity (w.b. – wet basis). The measurement system enabled quantitative and qualitative analyzes of volatile compounds and their emission intensity during the 10-day storage period. The study determined the profile of volatile compounds as a function of storage time and grain density level. The test results showed that the highest emission of volatile compounds was recorded in the first four days of storage of corn grain. VOC emissions, as well as grain moisture and volume, can be helpful in determining the quality of material stored in silos and its subsequent suitability for consumption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maize" title="maize">maize</a>, <a href="https://publications.waset.org/abstracts/search?q=consolidation" title=" consolidation"> consolidation</a>, <a href="https://publications.waset.org/abstracts/search?q=storage" title=" storage"> storage</a>, <a href="https://publications.waset.org/abstracts/search?q=VOCs" title=" VOCs"> VOCs</a>, <a href="https://publications.waset.org/abstracts/search?q=GC-MS" title=" GC-MS"> GC-MS</a>, <a href="https://publications.waset.org/abstracts/search?q=chemometrics" title=" chemometrics"> chemometrics</a> </p> <a href="https://publications.waset.org/abstracts/181130/the-impact-of-corn-grain-consolidation-on-the-emission-of-volatile-organic-compounds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181130.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">291</span> Influence of the Mixer on the Rheological Properties of the Fresh Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Nitsche">Alexander Nitsche</a>, <a href="https://publications.waset.org/abstracts/search?q=Piotr-Robert%20Lazik"> Piotr-Robert Lazik</a>, <a href="https://publications.waset.org/abstracts/search?q=Harald%20Garrecht"> Harald Garrecht</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The viscosity of the concrete has a great influence on the properties of the fresh concrete. Fresh concretes with low viscosity have a good flowability, whereas high viscosity has a lower flowability. Clearly, viscosity is directly linked to other parameters such as consistency, compaction, and workability of the concrete. The above parameters also depend very much on the energy induced during the mixing process and, of course, on the installation of the mixer itself. The University of Stuttgart has decided to investigate the influence of different mixing systems on the viscosity of various types of concrete, such as road concrete, self-compacting concrete, and lightweight concrete, using a rheometer and other testing methods. Each type is tested with three different mixers, and the rheological properties, namely consistency, and viscosity are determined. The aim of the study is to show that different types of concrete mixed with different types of mixers reach completely different yield points. Therefore, a 3 step procedure will be introduced. At first, various types of concrete mixtures and their differences are introduced. Then, the chosen suspension mixer and conventional mixers, which are going to be used in this paper, will be discussed. Lastly, the influence of the mixing system on the rheological properties of each of the select mix designs, as well as on fresh concrete, in general, will be presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rheological%20properties" title="rheological properties">rheological properties</a>, <a href="https://publications.waset.org/abstracts/search?q=flowability" title=" flowability"> flowability</a>, <a href="https://publications.waset.org/abstracts/search?q=suspension%20mixer" title=" suspension mixer"> suspension mixer</a>, <a href="https://publications.waset.org/abstracts/search?q=viscosity" title=" viscosity"> viscosity</a> </p> <a href="https://publications.waset.org/abstracts/118870/influence-of-the-mixer-on-the-rheological-properties-of-the-fresh-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118870.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">143</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">290</span> Database Playlists: Croatia's Popular Music in the Mirror of Collective Memory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diana%20Grguric">Diana Grguric</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Svetlacic"> Robert Svetlacic</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20Simovic"> Vladimir Simovic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Scientific research analytically explores database playlists by studying the memory culture through Croatian popular radio music. The research is based on the scientific analysis of databases developed on the basis of the playlist of ten Croatian radio stations. The most recent Croatian song on Statehood Day 2008-2013 is analyzed in order to gain insight into their (memory) potential in terms of storing, interpreting and presenting a national identity. The research starts with the general assumption that popular music is an efficient identifier, transmitter, and promoter of national identity. The aim of the scientific research of the database was to analytically reveal specific titles of Croatian popular songs that participate in marking memories and analyzing their symbolic capital to gain insight into the popular music experience of the past and to develop a new method of scientifically based analysis of specific databases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=specific%20databases" title="specific databases">specific databases</a>, <a href="https://publications.waset.org/abstracts/search?q=popular%20radio%20music" title=" popular radio music"> popular radio music</a>, <a href="https://publications.waset.org/abstracts/search?q=collective%20memory" title=" collective memory"> collective memory</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20identity" title=" national identity"> national identity</a> </p> <a href="https://publications.waset.org/abstracts/76007/database-playlists-croatias-popular-music-in-the-mirror-of-collective-memory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76007.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">356</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">289</span> The Role of Ionic Strength and Mineral Size to Zeta Potential for the Adhesion of P. putida to Mineral Surfaces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fathiah%20Mohamed%20Zuki">Fathiah Mohamed Zuki</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20George%20Edyvean"> Robert George Edyvean</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrostatic interaction energy (∆EEDL) is a part of the Extended Derjaguin-Landau-Verwey-Overbeek (XDLVO) theory, which, together with van der Waals (∆EVDW) and acid base (∆EAB) interaction energies, has been extensively used to investigate the initial adhesion of bacteria to surfaces. Electrostatic or electrical double layer interaction energy is considerably affected by surface potential, however it cannot be determined experimentally and is usually replaced by zeta (ζ) potential via electrophoretic mobility. This paper focuses on the effect of ionic concentration as a function of pH and the effect of mineral grain size on ζ potential. It was found that both ionic strength and mineral grain size play a major role in determining the value of ζ potential for the adhesion of P. putida to hematite and quartz surfaces. Higher ζ potential values lead to higher electrostatic interaction energies and eventually to higher total XDLVO interaction energy resulting in bacterial repulsion. <p
