Network attack would be oppressed if attribution techniques are capable to trace back to the attackers after the hacking event. Therefore attributing these attacks to a particular identification becomes one of the important tasks when analysts attempt to differentiate and profile the attacker behind a piece of attack trace. To assist analysts in expose attackers behind the scenes, this paper researches on the connections between attribution traces and proposes probabilistic relevance based attribution patterns. This method facilitates the evaluation of the plausibility relevance between different traceable identifications. Furthermore, through analyzing the connections among traces, it could confirm the existence probability of a certain organization as well as discover its affinitive partners by the means of drawing relevance matrix from attribution traces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attribution%20trace" title="attribution trace">attribution trace</a>, <a href="https://publications.waset.org/abstracts/search?q=probabilistic%20relevance" title=" probabilistic relevance"> probabilistic relevance</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20attack" title=" network attack"> network attack</a>, <a href="https://publications.waset.org/abstracts/search?q=attacker%20identification" title=" attacker identification"> attacker identification</a> </p> <a href="https://publications.waset.org/abstracts/61350/trace-network-a-probabilistic-relevant-pattern-recognition-approach-to-attribution-trace-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61350.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">366</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">391</span> Electronic Government Services Adoption from Multi-Nationalities Perspectives </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isaac%20Kofi%20Mensah">Isaac Kofi Mensah</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianing%20Mi"> Jianing Mi</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheng%20Feng"> Cheng Feng </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electronic government is the application of Information and Communication Technologies (ICTs) by the government to improve public service delivery to citizens and businesses.

Fulvic acid (FA) is class of compounds of humic substances and possesses various pharmacological properties. However, the effect of FA on inflammatory responses of the monocytes remains unclear. We investigated the regulatory effect of FA on homocysteine-induced COX-2 expression in human monocytes. Peripheral blood monocytes and U937 cells were kept as controls or pre-treated with FA, and then stimulated with homocysteine. The results show that pretreating monocytes with FA inhibited the homocysteine-induced COX-2 expression in a dose-dependent manner. The inhibitor for nuclear factor-kB (NF-kB) attenuated homocysteine-induced COX-2 expression. Our findings provide a molecular mechanism by which FA inhibit homocysteine-induced COX-2 expression in monocytes, and a basis for using FA in pharmaceutical therapy against inflammation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=homocysteine" title="homocysteine">homocysteine</a>, <a href="https://publications.waset.org/abstracts/search?q=monocytes" title=" monocytes"> monocytes</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclooxygenase-2" title=" cyclooxygenase-2"> cyclooxygenase-2</a>, <a href="https://publications.waset.org/abstracts/search?q=fulvic%20acid" title=" fulvic acid"> fulvic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-inflammation" title=" anti-inflammation"> anti-inflammation</a> </p> <a href="https://publications.waset.org/abstracts/3151/attenuation-of-homocysteine-induced-cyclooxygenase-2-expression-in-human-monocytes-by-fulvic-acid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3151.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">597</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">388</span> Design of Transformerless Electric Energy Router in Smart Home</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Weidong%20Fu">Weidong Fu</a>, <a href="https://publications.waset.org/abstracts/search?q=Qingsong%20Wang"> Qingsong Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Hua"> Wei Hua</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming%20Cheng"> Ming Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Giuseppe%20Buja"> Giuseppe Buja</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A single-phase transformerless electric energy router (TL-EER) is proposed for renewable energy management and power quality improvement in smart homes. The proposed TL-EER only contains four semiconductor switching devices, which reduces costs greatly compared to traditional electric energy routers. TL-EER functions as intelligent systems that optimize the flow and distribution of energy within a grid, enabling seamless interaction between generation, storage, and consumption. In addition, TL-EER operates in multiple modes and could be converted to diverse topologies by changing the states of relays. As for power quality, voltage and current compensating methods are adapted. Thus, high-quality electrical energy could be transferred to the load, and the grid-side power factor could be improved. Finally, laboratory prototypes are established to validate the effectiveness of the system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transformerless" title="transformerless">transformerless</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20energy%20router" title=" electric energy router"> electric energy router</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20flow" title=" power flow"> power flow</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20quality" title=" power quality"> power quality</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20factor" title=" power factor"> power factor</a> </p> <a href="https://publications.waset.org/abstracts/193534/design-of-transformerless-electric-energy-router-in-smart-home" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193534.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">9</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">387</span> Multivariate Genome-Wide Association Studies for Identifying Additional Loci for Myopia </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qiao%20Fan">Qiao Fan</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaobo%20Guo"> Xiaobo Guo</a>, <a href="https://publications.waset.org/abstracts/search?q=Junxian%20Zhu"> Junxian Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaohu%20Ding"> Xiaohu Ding</a>, <a href="https://publications.waset.org/abstracts/search?q=Ching-Yu%20Cheng"> Ching-Yu Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Tien-Yin%20Wong"> Tien-Yin Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=Mingguang%20He"> Mingguang He</a>, <a href="https://publications.waset.org/abstracts/search?q=Heping%20Zhang"> Heping Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xueqin%20Wang"> Xueqin Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A systematic, simultaneous analysis of multiple phenotypes in genome-wide association studies (GWASs) draws a great attention to integrate the signals from single phenotypes with increased power.

The cluster system is composed of the computers which are installed the MPICH2 in laboratory.

Experiment results show that using marble to make geopolymer mortar and concrete, the compressive strength after 28 days curing can reach 35 MPa and 25 MPa, respectively. The characteristics of marble-based geopolymer green mortar and concrete will keep testing for a long term in order to understand the effect parameters. The study is based on resource recovery and recycling. Its basic characteristics are low consumption, low carbon dioxide emission and high efficiency that meet the international tendency 'Circular Economy.' By comparing with Portland cement mortar and concrete, production 1 ton of marble-based geopolymer mortar and concrete, they can be saved around 50.3% and 49.6% carbon dioxide emission, respectively. Production 1 m3 of marble-based geopolymer concrete costs about 62 USD that cheaper than that of traditional Portland concrete. It is proved that the marble-based geopolymer concrete has great potential for further engineering development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=marble" title="marble">marble</a>, <a href="https://publications.waset.org/abstracts/search?q=geopolymer" title=" geopolymer"> geopolymer</a>, <a href="https://publications.waset.org/abstracts/search?q=geopolymer%20concrete" title=" geopolymer concrete"> geopolymer concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20emission" title=" CO₂ emission"> CO₂ emission</a> </p> <a href="https://publications.waset.org/abstracts/69034/a-study-on-marble-based-geopolymer-mortar-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69034.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">440</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">383</span> Evaluation of Turbulence Modelling of Gas-Liquid Two-Phase Flow in a Venturi</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mengke%20Zhan">Mengke Zhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheng-Gang%20Xie"> Cheng-Gang Xie</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian-Jun%20Shu"> Jian-Jun Shu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A venturi flowmeter is a common device used in multiphase flow rate measurement in the upstream oil and gas industry. Having a robust computational model for multiphase flow in a venturi is desirable for understanding the gas-liquid and fluid-pipe interactions and predicting pressure and phase distributions under various flow conditions. A steady Eulerian-Eulerian framework is used to simulate upward gas-liquid flow in a vertical venturi. The simulation results are compared with experimental measurements of venturi differential pressure and chord-averaged gas holdup in the venturi throat section. The choice of turbulence model is nontrivial in the multiphase flow modelling in a venturi. The performance cross-comparison of the k-ϵ model, Reynolds stress model (RSM) and shear-stress transport (SST) k-ω turbulence model is made in the study. In terms of accuracy and computational cost, the SST k-ω turbulence model is observed to be the most efficient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics%20%28CFD%29" title="computational fluid dynamics (CFD)">computational fluid dynamics (CFD)</a>, <a href="https://publications.waset.org/abstracts/search?q=gas-liquid%20flow" title=" gas-liquid flow"> gas-liquid flow</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulence%20modelling" title=" turbulence modelling"> turbulence modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=venturi" title=" venturi"> venturi</a> </p> <a href="https://publications.waset.org/abstracts/129246/evaluation-of-turbulence-modelling-of-gas-liquid-two-phase-flow-in-a-venturi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129246.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">173</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">382</span> Through 7S Model to Promote the Service Innovation Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cheng%20Fang%20Hsu">Cheng Fang Hsu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Call center is the core of building customer relationship management system.

Trust was measured using the classical trust game, allowing for a nuanced understanding of how these factors interact and influence trust. The findings reveal that higher levels of anonymity negatively impact trust, while identity curation can moderate this effect. Mechanism analysis uncovers how anonymity influences perceived reciprocity and group cohesion, and how curation can moderate these relationships. The results demonstrate a nuanced interaction between anonymity and trust, with variations across different curation levels.

Firstly, the dynamics of a PMSM was proved to be strictly passive. The position controller with an adaptive law was used to estimate the load torque to eliminate the chattering effects associated with the conventional sliding mode controller. The stability analysis of the overall position control system was carried out by adopting the passivity theorem instead of Lyapunov-type arguments. Finally, experimental results were provided to show that the good position tracking can be obtained, and exhibit robustness in the variations of the motor parameters and load torque disturbances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20law" title="adaptive law">adaptive law</a>, <a href="https://publications.waset.org/abstracts/search?q=passivity%20theorem" title=" passivity theorem"> passivity theorem</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet%20synchronous%20motor" title=" permanent magnet synchronous motor"> permanent magnet synchronous motor</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20mode%20control" title=" sliding mode control"> sliding mode control</a> </p> <a href="https://publications.waset.org/abstracts/10734/sliding-mode-position-control-for-permanent-magnet-synchronous-motors-based-on-passivity-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10734.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">468</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">377</span> Effect of Resveratrol and Ascorbic Acid on the Stability of Alfa-Tocopherol in Whey Protein Isolate Stabilized O/W Emulsions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lei%20Wang">Lei Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yingzhou%20Ni"> Yingzhou Ni</a>, <a href="https://publications.waset.org/abstracts/search?q=Amr%20M.%20Bakry"> Amr M.

In this study, alfa-tocopherol was encapsulated in the oil phase of an oil-in-water emulsion stabilized with whey protein isolate (WPI). The influence of WPI concentration and resveratrol or ascorbic acid on the decomposition of alfa-tocopherol in the emulsion during storage is discussed. Decomposition decreased as WPI concentrations increased. Decomposition was delayed at ascorbic acid/WPI molar ratios lower than 5 but was promoted at higher ratios. Resveratrol partitioned into the oil-water interface by binding to WPI and its cis-isomer is believed to have contributed most of the protective effect of this polyphenol. These results suggest the possibility of using the emulsifying and ligand-binging properties of WPI to produce carriers for simultaneous encapsulation of alfa-tocopherol and resveratrol in a single emulsion system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stability" title="stability">stability</a>, <a href="https://publications.waset.org/abstracts/search?q=alfa-tocopherol" title=" alfa-tocopherol"> alfa-tocopherol</a>, <a href="https://publications.waset.org/abstracts/search?q=resveratrol" title=" resveratrol"> resveratrol</a>, <a href="https://publications.waset.org/abstracts/search?q=whey%20protein%20isolate" title=" whey protein isolate"> whey protein isolate</a> </p> <a href="https://publications.waset.org/abstracts/32495/effect-of-resveratrol-and-ascorbic-acid-on-the-stability-of-alfa-tocopherol-in-whey-protein-isolate-stabilized-ow-emulsions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32495.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">528</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">376</span> Oncogenic Functions of Long Non-Coding RNA XIST in Human Nasopharyngeal Carcinoma by Targeting MiR-34a-5p</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cheng-Cao%20Sun">Cheng-Cao Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Shu-Jun%20Li"> Shu-Jun Li</a>, <a href="https://publications.waset.org/abstracts/search?q=De-Jia%20Li"> De-Jia Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Long non-coding RNA (lncRNA) X inactivate-specific transcript (XIST) has been verified as an oncogenic gene in several human malignant tumors, and its dysregulation was closed associated with tumor initiation, development and progression. Nevertheless, whether the aberrant expression of XIST in human nasopharyngeal carcinoma (NPC) is corrected with malignancy, metastasis or prognosis has not been elaborated. Here, we discovered that XIST was up-regulated in NPC tissues and higher expression of XIST contributed to a markedly poorer survival time. In addition, multivariate analysis demonstrated XIST was an independent risk factor for prognosis. XIST over-expression enhanced, while XIST silencing hampered the cell growth in NPC. Additionally, mechanistic analysis revealed that XIST up-regulated the expression of miR-34a-5p targeted gene E2F3 through acting as a competitive ‘sponge’ of miR-34a-5p. Taking all into account, we concluded that XIST functioned as an oncogene in NPC through up-regulating E2F3 in part through ‘spongeing’ miR-34a-5p. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=X%20inactivate-specific%20transcript%3B%20hsa-miRNA-34a-5p" title="X inactivate-specific transcript; hsa-miRNA-34a-5p">X inactivate-specific transcript; hsa-miRNA-34a-5p</a>, <a href="https://publications.waset.org/abstracts/search?q=miR-34a-5p%3B%20E2F3" title=" miR-34a-5p; E2F3"> miR-34a-5p; E2F3</a>, <a href="https://publications.waset.org/abstracts/search?q=nasopharyngeal%20carcinoma" title=" nasopharyngeal carcinoma"> nasopharyngeal carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=tumorigenesis" title=" tumorigenesis"> tumorigenesis</a> </p> <a href="https://publications.waset.org/abstracts/54940/oncogenic-functions-of-long-non-coding-rna-xist-in-human-nasopharyngeal-carcinoma-by-targeting-mir-34a-5p" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54940.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">240</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">375</span> The Types of Collaboration Models Driven by Public Art Establishment–Case Study of Taichung City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cheng-Lung%20Yu">Cheng-Lung Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying-His%20Liao"> Ying-His Liao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Some evidence show that public art accelerates local economic growth.

A general augmented reality theory has been explored in the very beginning and afterwards a systematic process model is proposed. There are three major core tasks to be done for the platform, i.e. 1) constructing the physical interactive table, 2) designing the media, and 3) designing the media carrier.

As a result, a systematic process with thirteen steps has been developed and it aims at providing a rational method for constructing the platform. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human-computer%20interaction" title="human-computer interaction">human-computer interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=media" title=" media"> media</a>, <a href="https://publications.waset.org/abstracts/search?q=media%20carrier" title=" media carrier"> media carrier</a>, <a href="https://publications.waset.org/abstracts/search?q=augmented%20reality%20display%20platform" title=" augmented reality display platform"> augmented reality display platform</a> </p> <a href="https://publications.waset.org/abstracts/18782/systematic-process-for-constructing-an-augmented-reality-display-platform" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18782.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">415</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">373</span> Horizon Scanning of Disruptive Technology Trends in Marine for 2030 Horizon </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20Gonzalez">Jose Gonzalez</a>, <a href="https://publications.waset.org/abstracts/search?q=Fai%20Cheng"> Fai Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivy%20Fan"> Ivy Fan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Shipping has a mature and ever expanding worldwide market. The future of the marine industry itself is not only irrevocably linked with the global economic, social, and political landscape; it is also subject to the technological developments in different fields. Some of them may have never been linked to the marine industry before. Companies in the marine sector are getting more dependent on technologies to achieve competitive advantage in an increasing open market. Technologies can be fused across different business functions and geopolitical influences. A successful marine business should be prepared to embrace such potential changes that lie ahead. The present paper intends to articulate long-term marine technology strategies from an industrial perspective. Methodology and current development are introduced. The paper will also provide insight into future technological trends demand for major commercial ship types.

As residents' daily commuting necessities, cars cause a lot of exhaust emissions and urban traffic congestion. In the "Fourteenth Five Year Plan" of China, it is proposed to strive to reach the peak of carbon dioxide emissions by 2030 and achieve carbon neutrality by 2060. Urban transport accounts for a high proportion of carbon emission sources. It is an important driving force for the realization of China's carbon peak strategy. Some cities have introduced and implemented the policy of "car restriction" to solve related urban problems by reducing the use of cars. This paper analyzes the implementation of the "automobile restriction" policy, evaluates the relevant effects of the automobile restriction policy, and discusses how to better optimize the "automobile restriction" policy in the process of urban governance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20emission" title="carbon emission">carbon emission</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20jams" title=" traffic jams"> traffic jams</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20restrictions" title=" vehicle restrictions"> vehicle restrictions</a>, <a href="https://publications.waset.org/abstracts/search?q=evaluate" title=" evaluate"> evaluate</a> </p> <a href="https://publications.waset.org/abstracts/159386/research-on-the-public-policy-of-vehicle-restriction-under-traffic-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159386.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">160</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">370</span> Yaw Angle Effect on the Aerodynamic Performance of Rear-Roof Spoiler of Hatchback Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=See-Yuan%20Cheng">See-Yuan Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Kwang-Yhee%20Chin"> Kwang-Yhee Chin</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuhaimi%20Mansor"> Shuhaimi Mansor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rear-roof spoiler is commonly used for improving the aerodynamic performance of road vehicles. This study aims to investigate the effect of yaw angle on the effectiveness of strip-type rear-roof spoiler in providing lower drag and lift coefficients of a hatchback model. A computational fluid dynamics (CFD) method was used. The numerically obtained results were compared to the experimental data for validation of the CFD method. At increasing yaw angle, both the drag and lift coefficients of the model were to increase. In addition, the effectiveness of spoiler was deteriorated. These unfavorable effects were due to the formation of longitudinal vortices around the side edges of the model that had caused the surface pressure of the model to drop. Furthermore, there were significant crossflow structures developed behind the model at larger yaw angle, which were associated with the drop in the surface pressure of the rear section of the model and cause the drag coefficient to rise. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20model" title="Ahmed model">Ahmed model</a>, <a href="https://publications.waset.org/abstracts/search?q=aerodynamics" title=" aerodynamics"> aerodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=spoiler" title=" spoiler"> spoiler</a>, <a href="https://publications.waset.org/abstracts/search?q=yaw%20angle" title=" yaw angle"> yaw angle</a> </p> <a href="https://publications.waset.org/abstracts/58516/yaw-angle-effect-on-the-aerodynamic-performance-of-rear-roof-spoiler-of-hatchback-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58516.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">357</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">369</span> Shielding Effectiveness of Rice Husk and CNT Composites in X-Band Frequency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20S.%20Lee">Y.

The rectangular wave guide technique was used to measure the complex permittivity of the RHCNTs composites materials. The complex permittivity is represented in terms of both the real and imaginary parts of permittivity in X-band frequency. The conductivity of RHCNTs shows increasing when the ratio of CNTs mixture increases. The composites materials were simulated using Computer Simulation Technology (CST) Microwave Studio simulation software. The shielding effectiveness of RHCNTs and pure rice husk was compared.

Methods: A literature review was performed of published cases of surgery in patients with HAE. Results were limited to English language only and cases were examined for management strategies and successful prevention of acute attacks. Results: The literature revealed the successful use of C1 esterase inhibitors as the most common agent in surgical prophylaxis therapy. Other therapeutic targets described included kallikrein inhibitors and bradykinin B2 receptor antagonists. Conclusions: Therapeutic targets that exist for the management of acute attacks in HAE have been successfully employed in the setting of surgery. The data is currently limited and could not be used as a firm evidence base, but the limited outcomes seen are positive and reassuring for the prospective anesthetic management of this potentially fatal condition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anesthesia" title="anesthesia">anesthesia</a>, <a href="https://publications.waset.org/abstracts/search?q=C1%20esterase%20deficiency" title=" C1 esterase deficiency"> C1 esterase deficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=hereditary%20angioedema" title=" hereditary angioedema"> hereditary angioedema</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical%20prophylaxis" title=" surgical prophylaxis"> surgical prophylaxis</a> </p> <a href="https://publications.waset.org/abstracts/34031/hereditary-angioedema-case-presentation-and-review-of-anaesthetic-implications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34031.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">364</span> Equivalent Circuit Model for the Eddy Current Damping with Frequency-Dependence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhiguo%20Shi">Zhiguo Shi</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheng%20Ning%20Loong"> Cheng Ning Loong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiazeng%20Shan"> Jiazeng Shan</a>, <a href="https://publications.waset.org/abstracts/search?q=Weichao%20Wu">Weichao Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study proposes an equivalent circuit model to simulate the eddy current damping force with shaking table tests and finite element modeling.

The results indicated that miR-1275 was significantly down-regulated in primary NPC tissues, and very low levels were found in NPC cell lines. Ectopic expression of miR-1275 in NPC cell lines significantly suppressed cell growth as evidenced by cell viability assay and colony formation assay, through inhibition of HOXB5. In addition, miR-1275 suppresses G1/S transition through inhibition of HOXB5. Further, oncogene HOXB5 was revealed to be a putative target of miR-1275, which was inversely correlated with miR-1275 expression in NPC. Collectively, our study demonstrates that as a tumor suppressor, miR-1275 played a pivotal role on NPC through inhibiting cell proliferation, and suppressing G1/S transition by targeting oncogenic HOXB5. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microRNA-1275%20%28miR-1275%29" title="microRNA-1275 (miR-1275)">microRNA-1275
