Here attention has been focused on Levy model, more reliable and realistic than classical random Gaussian one as it takes into consideration observed abrupt jumps in case of sudden price variation. In application to Energy Trading sector where it has never been used before, equations corresponding to Levy model have been written for electricity pricing in European market. Parameters have been set in order to predict and simulate the price and its evolution through time to remarkable accuracy. As predicted by Levy model, the results show significant spikes which reach unconventional levels contrary to currently used Brownian model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=commodity%20pricing" title="commodity pricing">commodity pricing</a>, <a href="https://publications.waset.org/abstracts/search?q=L%C3%A9vy%20Model" title=" Lévy Model"> Lévy Model</a>, <a href="https://publications.waset.org/abstracts/search?q=price%20spikes" title=" price spikes"> price spikes</a>, <a href="https://publications.waset.org/abstracts/search?q=electricity%20market" title=" electricity market"> electricity market</a> </p> <a href="https://publications.waset.org/abstracts/14039/levy-model-for-commodity-pricing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14039.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">429</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">39</span> Modeling Environmental, Social, and Governance Financial Assets with Lévy Subordinated Processes and Option Pricing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abootaleb%20Shirvani">Abootaleb Shirvani</a>, <a href="https://publications.waset.org/abstracts/search?q=Svetlozar%20Rachev"> Svetlozar Rachev</a> </p> <p class="card-text"><strong>Abstract:</strong></p> ESG stands for Environmental, Social, and Governance and is a non-financial factor that investors use to specify material risks and growth opportunities in their analysis process. ESG ratings provide a quantitative measure of socially responsible investment, and it is essential to incorporate ESG ratings when modeling the dynamics of asset returns. In this article, we propose a triple subordinated Lévy process for incorporating numeric ESG ratings into dynamic asset pricing theory to model the time series properties of the stock returns. The motivation for introducing three layers of subordinator is twofold. The first two layers of subordinator capture the skew and fat-tailed properties of the stock return distribution that cannot be explained well by the existing Lévy subordinated model. The third layer of the subordinator introduces ESG valuation and incorporates numeric ESG ratings into dynamic asset pricing theory and option pricing. We employ the triple subordinator Lévy model for developing the ESG-valued stock return model, derive the implied ESG score surfaces for Microsoft, Apple, and Amazon stock returns, and compare the shape of the ESG implied surface scores for these stocks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ESG%20scores" title="ESG scores">ESG scores</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20asset%20pricing%20theory" title=" dynamic asset pricing theory"> dynamic asset pricing theory</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20subordinated%20modeling" title=" multiple subordinated modeling"> multiple subordinated modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=L%C3%A9vy%20processes" title=" Lévy processes"> Lévy processes</a>, <a href="https://publications.waset.org/abstracts/search?q=option%20pricing" title=" option pricing"> option pricing</a> </p> <a href="https://publications.waset.org/abstracts/160773/modeling-environmental-social-and-governance-financial-assets-with-levy-subordinated-processes-and-option-pricing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160773.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">81</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Modeling Default Probabilities of the Chosen Czech Banks in the Time of the Financial Crisis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Petr%20Gurn%C3%BD">Petr Gurný</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the most important tasks in the risk management is the correct determination of probability of default (PD) of particular financial subjects. In this paper a possibility of determination of financial institution’s PD according to the credit-scoring models is discussed. The paper is divided into the two parts. The first part is devoted to the estimation of the three different models (based on the linear discriminant analysis, logit regression and probit regression) from the sample of almost three hundred US commercial banks. Afterwards these models are compared and verified on the control sample with the view to choose the best one. The second part of the paper is aimed at the application of the chosen model on the portfolio of three key Czech banks to estimate their present financial stability. However, it is not less important to be able to estimate the evolution of PD in the future. For this reason, the second task in this paper is to estimate the probability distribution of the future PD for the Czech banks. So, there are sampled randomly the values of particular indicators and estimated the PDs’ distribution, while it’s assumed that the indicators are distributed according to the multidimensional subordinated Lévy model (Variance Gamma model and Normal Inverse Gaussian model, particularly). Although the obtained results show that all banks are relatively healthy, there is still high chance that “a financial crisis” will occur, at least in terms of probability. This is indicated by estimation of the various quantiles in the estimated distributions. Finally, it should be noted that the applicability of the estimated model (with respect to the used data) is limited to the recessionary phase of the financial market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=credit-scoring%20models" title="credit-scoring models">credit-scoring models</a>, <a href="https://publications.waset.org/abstracts/search?q=multidimensional%20subordinated%20L%C3%A9vy%20model" title=" multidimensional subordinated Lévy model"> multidimensional subordinated Lévy model</a>, <a href="https://publications.waset.org/abstracts/search?q=probability%20of%20default" title=" probability of default"> probability of default</a> </p> <a href="https://publications.waset.org/abstracts/19463/modeling-default-probabilities-of-the-chosen-czech-banks-in-the-time-of-the-financial-crisis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19463.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">456</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">37</span> Multi-Agent Searching Adaptation Using Levy Flight and Inferential Reasoning </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sagir%20M.%20Yusuf">Sagir M.

Bayesian Belief Network was used to monitor agents' knowledge about their environment, and cases are recorded for the network training using expectation-maximisation or gradient descent algorithm. The well trained network will be used for decision making and environmental situation prediction. Forest fire searching by multiple UAVs was the use case. UAVs are tasked to explore a forest and find a fire for urgent actions by the fire wardens. The paper focused on two problems: (i) effective agents’ path planning strategy and (ii) knowledge understanding and prediction (SA). The path planning problem by inspiring animal mode of foraging using Lévy distribution augmented with Bayesian reasoning was fully described in this paper. Results proof that the Lévy flight strategy performs better than the previous fixed-pattern (e.g., parallel sweeps) approaches in terms of energy and time utilisation. We also introduced a waypoint assessment strategy called k-previous waypoints assessment. It improves the performance of the ordinary levy flight by saving agent’s resources and mission time through redundant search avoidance. The agents (UAVs) are to report their mission knowledge at the central server for interpretation and prediction purposes. Bayesian reasoning and learning were used for the SA and results proof effectiveness in different environments scenario in terms of prediction and effective knowledge representation. The prediction accuracy was measured using learning error rate, logarithm loss, and Brier score and the result proves that little agents mission that can be used for prediction within the same or different environment. Finally, we described a situation-based knowledge visualization and prediction technique for heterogeneous multi-UAV mission. While this paper proves linkage of Bayesian reasoning and learning with SA and effective searching strategy, future works is focusing on simplifying the architecture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Levy%20flight" title="Levy flight">Levy flight</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20constraint%20optimization%20problem" title=" distributed constraint optimization problem"> distributed constraint optimization problem</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-agent%20system" title=" multi-agent system"> multi-agent system</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-robot%20coordination" title=" multi-robot coordination"> multi-robot coordination</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomous%20system" title=" autonomous system"> autonomous system</a>, <a href="https://publications.waset.org/abstracts/search?q=swarm%20intelligence" title=" swarm intelligence"> swarm intelligence</a> </p> <a href="https://publications.waset.org/abstracts/116932/multi-agent-searching-adaptation-using-levy-flight-and-inferential-reasoning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116932.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">144</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">36</span> Exact Vibration Analysis of a Rectangular Nano-Plate Using Nonlocal Modified Sinusoidal Shear Deformation Theory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Korosh%20Khorshidi">Korosh Khorshidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Khodadadi"> Mohammad Khodadadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, exact close form solution for out of plate free flexural vibration of moderately thick rectangular nanoplates are presented based on nonlocal modified trigonometric shear deformation theory, with assumptions of the Levy's type boundary conditions, for the first time. The aim of this study is to evaluate the effect of small-scale parameters on the frequency parameters of the moderately thick rectangular nano-plates. To describe the effects of small-scale parameters on vibrations of rectangular nanoplates, the Eringen theory is used. The Levy's type boundary conditions are combination of six different boundary conditions; specifically, two opposite edges are simply supported and any of the other two edges can be simply supported, clamped or free. Governing equations of motion and boundary conditions of the plate are derived by using the Hamilton’s principle. The present analytical solution can be obtained with any required accuracy and can be used as benchmark. Numerical results are presented to illustrate the effectiveness of the proposed method compared to other methods reported in the literature. Finally, the effect of boundary conditions, aspect ratios, small scale parameter and thickness ratios on nondimensional natural frequency parameters and frequency ratios are examined and discussed in detail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exact%20solution" title="exact solution">exact solution</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlocal%20modified%20sinusoidal%20shear%20deformation%20theory" title=" nonlocal modified sinusoidal shear deformation theory"> nonlocal modified sinusoidal shear deformation theory</a>, <a href="https://publications.waset.org/abstracts/search?q=out%20of%20plane%20vibration" title=" out of plane vibration"> out of plane vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=moderately%20thick%20rectangular%20plate" title=" moderately thick rectangular plate"> moderately thick rectangular plate</a> </p> <a href="https://publications.waset.org/abstracts/36318/exact-vibration-analysis-of-a-rectangular-nano-plate-using-nonlocal-modified-sinusoidal-shear-deformation-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36318.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">388</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">35</span> Two Steady States and Two Movement Patterns under the Balanced Budget Rule: An Economy with Divisible Labor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fujio%20Takata">Fujio Takata</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When governments levy taxes on labor income on the basis of a balanced budget rule, two steady states in an economy exist, of which one can cause two movement patterns, namely, indeterminacy paths and a saddle path. However, in this paper, we assume an economy with divisible labor, in which labor adjustment is made by an intensive margin. We demonstrate that there indeed exist the two paths in the economy and that there exists a critical condition dividing them. This is proved by establishing the relationship between a finite elasticity of labor with regard to real wages and the share of capital in output. Consequently, we deduce the existence of an upper limit in the share of capital in output for indeterminacy to occur. The largest possible value of that share is less than 0.5698. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=balanced%20budget%20rule" title="balanced budget rule">balanced budget rule</a>, <a href="https://publications.waset.org/abstracts/search?q=divisible%20labor" title=" divisible labor"> divisible labor</a>, <a href="https://publications.waset.org/abstracts/search?q=labor%20income%20taxation" title=" labor income taxation"> labor income taxation</a>, <a href="https://publications.waset.org/abstracts/search?q=two%20movement%20patterns" title=" two movement patterns"> two movement patterns</a> </p> <a href="https://publications.waset.org/abstracts/134178/two-steady-states-and-two-movement-patterns-under-the-balanced-budget-rule-an-economy-with-divisible-labor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134178.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">163</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">34</span> Optimization of Copper-Water Negative Inclination Heat Pipe with Internal Composite Wick Structure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Brandys">I.

This structure creates power consumption variations depending on the transmitted data of a factor of more than 2 between minimum and maximum. The power generation unit has to consider therefore the worst case maximum consumption all the time and be built accordingly. This paper proposes a method to reduce both the average current consumption and worst case current consumption. The transmitter randomizes the data using several pseudo-random sequences. It then estimates the energy consumption of the generated frames and selects to transmit the one which consumes the least. The transmitter also prepends the index of the pseudo-random sequence, which is not randomized, to allow the receiver to recover the original data using the correct sequence. We show that in the case that the frame occupies most of the DSI3 synchronization period, we achieve average power consumption reduction by up to 13% and the worst case power consumption is reduced by 17.7%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DSI3" title="DSI3">DSI3</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20consumption" title=" power consumption"> power consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=randomization" title=" randomization"> randomization</a> </p> <a href="https://publications.waset.org/abstracts/18945/reduced-power-consumption-by-randomization-for-dsi3" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18945.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">538</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">32</span> 'You Block Yourself from the Emotion': A Qualitative Inquiry into Teacher's Use of Discordant Emotional Labor Strategies in Student Aggression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michal%20Levy">Michal Levy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite the emotional impact students' misbehavior and aggression has on teacher's emotional wellbeing, teachers frequently use suppressive strategies in the classroom, which maintain a discordance between felt and expressed emotions. The current study sought to gain a deeper insight into teachers' utilization of discordant emotional labor strategies (i.e., expressive suppression, surface acting and emotional dissonance) and their motives to using these strategies in student aggression. A qualitative study was conducted on 16 special education Jewish Israeli teachers. Thematic analysis of the in-depth semi-structured interviews revealed novice teachers were inclined to use expressive suppression, while experienced teachers used emotional dissonance. The teacher's motives for using discordant emotional labor strategies included both instrumental and hedonic goals. Implications for policymakers and professionals in practice are discussed to improve teachers' emotional wellbeing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=discordant%20strategies" title="discordant strategies">discordant strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=emotional%20labor" title=" emotional labor"> emotional labor</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20aggression" title=" student aggression"> student aggression</a>, <a href="https://publications.waset.org/abstracts/search?q=teachers" title=" teachers"> teachers</a> </p> <a href="https://publications.waset.org/abstracts/138520/you-block-yourself-from-the-emotion-a-qualitative-inquiry-into-teachers-use-of-discordant-emotional-labor-strategies-in-student-aggression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138520.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">261</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">31</span> Tetraploid Induction in the Yellowtail Tetra Astyanax altiparanae</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nivaldo%20Ferreira%20do%20Nascimento">Nivaldo Ferreira do Nascimento</a>, <a href="https://publications.waset.org/abstracts/search?q=Matheus%20Pereira-Santos"> Matheus Pereira-Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Nycolas%20Levy-Pereira"> Nycolas Levy-Pereira</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Augusto%20Senhorini"> José Augusto Senhorini</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20Shigueki%20Yasui"> George Shigueki Yasui</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Satiko%20Okada%20Nakaghi"> Laura Satiko Okada Nakaghi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tetraploid individuals, which could produce diploid gametes, can be used for production of 100% triploid fish. Therefore, the aim of this study was to develop a tetraploidization protocol for A. altiparanae. We tested the effect of heat shock (40 °C; 2 min) at 16, 18, 20, 22, 24 and 26 minutes post fertilization (mpf). Untreated eggs were used as control. After hatching, ploidy status of the larvae was checked by flow cytometry. No difference were observed for the hatching rate between all treatments (P = 0.5974). However, we observed an increase in the larval abnormality in the heat shock treatments, in special at 22 (82.17 ± 6.66%) 24 (78.31 ±7.28%) and 26 mpf (79.01 ± 7.85%) in comparison with the control group (12.87 ± 4.46%). No tetraploid was observed at 16 and 18 mpf. The higher number of tetraploid individuals (52/55) was observed at 26 mpf. Our results showed that high percentages of tetraploids are obtained by heat shock (40°C; 2min) at 26 mpf, which could enable the mass production of triploid individuals in A. altiparanae. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chromosome%20manipulation" title="chromosome manipulation">chromosome manipulation</a>, <a href="https://publications.waset.org/abstracts/search?q=polyploidy" title=" polyploidy"> polyploidy</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20cytometry" title=" flow cytometry"> flow cytometry</a>, <a href="https://publications.waset.org/abstracts/search?q=tetraploidization" title=" tetraploidization"> tetraploidization</a> </p> <a href="https://publications.waset.org/abstracts/70446/tetraploid-induction-in-the-yellowtail-tetra-astyanax-altiparanae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70446.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">333</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">30</span> Integrative System of GDP, Emissions, Health Services and Population Health in Vietnam: Dynamic Panel Data Estimation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ha%20Hai%20Duong">Ha Hai Duong</a>, <a href="https://publications.waset.org/abstracts/search?q=Amnon%20Levy%20Livermore"> Amnon Levy Livermore</a>, <a href="https://publications.waset.org/abstracts/search?q=Kankesu%20Jayanthakumaran"> Kankesu Jayanthakumaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Oleg%20Yerokhin"> Oleg Yerokhin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The issues of economic development, the environment and human health have been investigated since 1990s. Previous researchers have found different empirical evidences of the relationship between income and environmental pollution, health as determinant of economic growth, and the effects of income and environmental pollution on health in various regions of the world. This paper concentrates on integrative relationship analysis of GDP, carbon dioxide emissions, and health services and population health in context of Vietnam. We applied the dynamic generalized method of moments (GMM) estimation on datasets of Vietnam’s sixty-three provinces for the years 2000-2010. Our results show the significant positive effect of GDP on emissions and the dependence of population health on emissions and health services. We find the significant relationship between population health and GDP. Additionally, health services are significantly affected by population health and GDP. Finally, the population size too is other important determinant of both emissions and GDP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=economic%20development" title="economic development">economic development</a>, <a href="https://publications.waset.org/abstracts/search?q=emissions" title=" emissions"> emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20pollution" title=" environmental pollution"> environmental pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a> </p> <a href="https://publications.waset.org/abstracts/24314/integrative-system-of-gdp-emissions-health-services-and-population-health-in-vietnam-dynamic-panel-data-estimation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24314.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">626</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">29</span> Skew Planar Wheel Antenna for First Person View of Unmanned Aerial Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raymond%20Yudhi%20Purba">Raymond Yudhi Purba</a>, <a href="https://publications.waset.org/abstracts/search?q=Levy%20Olivia%20Nur"> Levy Olivia Nur</a>, <a href="https://publications.waset.org/abstracts/search?q=Radial%20Anwar"> Radial Anwar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research presents the design and measurement of a skew planar wheel antenna that is used to visualize the first person view perspective of unmanned aerial vehicles.

It is not clear, however, whether conflicting information about outcome probabilities affects decision making in the same manner as ambiguity does. Here we combine functional Magnetic Resonance Imaging (fMRI) and a simple gamble design to study this question. In this design, the levels of ambiguity and conflict are parametrically varied, and ambiguity and conflict gambles are matched on both expected value and variance. Behaviorally, participants avoided conflict more than ambiguity, and attitudes toward ambiguity and conflict did not correlate across subjects. Neurally, regional brain activation was differentially modulated by ambiguity level and aversion to ambiguity and by conflict level and aversion to conflict. Activation in the medial prefrontal cortex was correlated with the level of ambiguity and with ambiguity aversion, whereas activation in the ventral striatum was correlated with the level of conflict and with conflict aversion. This novel double dissociation indicates that decision makers process imprecise and conflicting information differently, a finding that has important implications for basic and clinical research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decision%20making" title="decision making">decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty" title=" uncertainty"> uncertainty</a>, <a href="https://publications.waset.org/abstracts/search?q=ambiguity" title=" ambiguity"> ambiguity</a>, <a href="https://publications.waset.org/abstracts/search?q=conflict" title=" conflict"> conflict</a>, <a href="https://publications.waset.org/abstracts/search?q=fMRI" title=" fMRI"> fMRI</a> </p> <a href="https://publications.waset.org/abstracts/27681/neural-correlates-of-decision-making-under-ambiguity-and-conflict" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27681.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">564</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">27</span> Improved Multi–Objective Firefly Algorithms to Find Optimal Golomb Ruler Sequences for Optimal Golomb Ruler Channel Allocation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shonak%20Bansal">Shonak Bansal</a>, <a href="https://publications.waset.org/abstracts/search?q=Prince%20Jain"> Prince Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Arun%20Kumar%20Singh"> Arun Kumar Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Neena%20Gupta"> Neena Gupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently nature–inspired algorithms have widespread use throughout the tough and time consuming multi–objective scientific and engineering design optimization problems.

Delamination tips are mostly captured by spatial numerical models in order to predict crack growth. This paper presents some mechanical models of delaminated composite shells based on shallow shell theories. The mechanical fields are based on a third-order displacement field in terms of the through-thickness coordinate of the laminated shell. The undelaminated and delaminated parts are captured by separate models and the continuity and boundary conditions are also formulated in a general way providing a large size boundary value problem. The system of differential equations is solved by the state space method for an elliptic delaminated shell having simply supported edges. The comparison of the proposed and a numerical model indicates that the primary indicator of the model is the deflection, the secondary is the widthwise distribution of the energy release rate. The model is promising and suitable to determine accurately the J-integral distribution along the delamination front. Based on the proposed model it is also possible to develop finite elements which are able to replace the computationally expensive spatial models of delaminated structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=J-integral" title="J-integral">J-integral</a>, <a href="https://publications.waset.org/abstracts/search?q=levy%20method" title=" levy method"> levy method</a>, <a href="https://publications.waset.org/abstracts/search?q=third-order%20shell%20theory" title=" third-order shell theory"> third-order shell theory</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20space%20solution" title=" state space solution"> state space solution</a> </p> <a href="https://publications.waset.org/abstracts/110163/analytical-solution-of-the-boundary-value-problem-of-delaminated-doubly-curved-composite-shells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110163.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> A Unique Professional Development of Teacher Educators: Teaching Colleagues </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naomi%20Weiner-Levy">Naomi Weiner-Levy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Mofet Institute of Research, established a School of Professional Development, the only one of its kind in Israel and throughout the world. It offers specialized programs for teacher educators, providing them with the professional knowledge and skills. The studies aim at updating teachers about rapidly changing knowledge and skills. Teacher educators are conceptualized as shifting from first order practitioners (school teachers) to second order practitioners. Those who train teachers are referred to as third order practitioners. The instructors in the School of Professional Development are third-order practitioners – teacher educators specializing in teaching their colleagues. Collegial guidance by teachers’ college staff members is no simple task: Tutors must be expert in their field of specialization, as well as in instruction. Moreover, although colleagues, they have to position themselves within the group as authoritative figures in terms of instruction and knowledge. To date, the role and professional identity of these third-order practitioners, has not been studied. To understand the nature and development of professional identity, a qualitative study was conducted in which 12 tutors of various subjects were interviewed. These were analyzed by categorical content analysis. The findings, assessed professional identity through a post-modern prism, while examining the interplay among events that tutors experienced, the knowledge they acquired and the structuring of their professional identity. The Tutors’ identity transformed through negotiating with ‘self’ and ‘other’ in the class, and constructed by their mutual experiences as tutors and learners. Understanding the function and identity of tutors facilitates comprehension of this unique training process for teacher educators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=professional%20development" title="professional development">professional development</a>, <a href="https://publications.waset.org/abstracts/search?q=professional%20identity" title=" professional identity"> professional identity</a>, <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=tutoring" title=" tutoring"> tutoring</a> </p> <a href="https://publications.waset.org/abstracts/76885/a-unique-professional-development-of-teacher-educators-teaching-colleagues" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76885.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">223</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">24</span> The Nexus between Country Risk and Exchange Rate Regimes: A Global Investigation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jie%20Liu">Jie Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Wei"> Wei Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun-Ping%20Chang"> Chun-Ping Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Using a sample of 110 countries over the period 1984-2013, this paper examines the impacts of country risks on choosing a specific exchange rate regime (first by utilizing the Levy-Yeyati and Sturzenegger de facto classification and then robusting it by the IMF de jure measurement) relative to other regimes via the panel multinomial logit approach. Empirical findings are as follows. First, in the full samples case we provide evidence that government is more likely to implement a flexible regime, but less likely to adopt a fixed regime, under a low level of composite and financial risk. Second, we find that Eurozone countries are more likely to choose a fixed exchange rate regime with a decrease in the level of country risk and favor a flexible regime in response to a shock from an increase of risk, which is opposite to non-Eurozone countries. Third, we note that high-risk countries are more likely to choose a fixed regime with a low level of composite and political risk in the government, but do not adjust the exchange rate regime as a shock absorber when facing economic and financial risks. It is interesting to see that those countries with relatively low risk display almost opposite results versus high-risk economies. Overall, we believe that it is critically important to account for political economy variables in a government’s exchange rate policy decisions, especially for country risks. All results are robust to the panel ordered probit model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=country%20risk" title="country risk">country risk</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20economy" title=" political economy"> political economy</a>, <a href="https://publications.waset.org/abstracts/search?q=exchange%20rate%20regimes" title=" exchange rate regimes"> exchange rate regimes</a>, <a href="https://publications.waset.org/abstracts/search?q=shock%20absorber" title=" shock absorber"> shock absorber</a> </p> <a href="https://publications.waset.org/abstracts/49375/the-nexus-between-country-risk-and-exchange-rate-regimes-a-global-investigation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49375.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">302</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">23</span> Decision-Making Under Uncertainty in Obsessive-Compulsive Disorder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helen%20Pushkarskaya">Helen Pushkarskaya</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Tolin"> David Tolin</a>, <a href="https://publications.waset.org/abstracts/search?q=Lital%20Ruderman"> Lital Ruderman</a>, <a href="https://publications.waset.org/abstracts/search?q=Ariel%20Kirshenbaum"> Ariel Kirshenbaum</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20MacLaren%20Kelly"> J.

Difficulties with decision making and intolerance of uncertainty are prominent clinical features of OCD. The nature and etiology of these deficits are poorly understood. We used a well-validated choice task, grounded in behavioral economic theory, to investigate differences in valuation and value-based choice during decision making under uncertainty in 20 unmedicated participants with OCD and 20 matched healthy controls. Participants’ choices were used to assess individual decision-making characteristics. Compared to controls, individuals with OCD were less consistent in their choices and less able to identify options that were unambiguously preferable. These differences correlated with symptom severity. OCD participants did not differ from controls in how they valued uncertain options when outcome probabilities were known (risk) but were more likely than controls to avoid uncertain options when these probabilities were imprecisely specified (ambiguity). These results suggest that the underlying neural mechanisms of valuation and value-based choices during decision-making are abnormal in OCD. Individuals with OCD show elevated intolerance of uncertainty, but only when outcome probabilities are themselves uncertain. Future research focused on the neural valuation network, which is implicated in value-based computations, may provide new neurocognitive insights into the pathophysiology of OCD. Deficits in decision-making processes may represent a target for therapeutic intervention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=obsessive%20compulsive%20disorder" title="obsessive compulsive disorder">obsessive compulsive disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=decision-making" title=" decision-making"> decision-making</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty%20intolerance" title=" uncertainty intolerance"> uncertainty intolerance</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20aversion" title=" risk aversion"> risk aversion</a>, <a href="https://publications.waset.org/abstracts/search?q=ambiguity%20aversion" title=" ambiguity aversion"> ambiguity aversion</a>, <a href="https://publications.waset.org/abstracts/search?q=valuation" title=" valuation"> valuation</a> </p> <a href="https://publications.waset.org/abstracts/27674/decision-making-under-uncertainty-in-obsessive-compulsive-disorder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27674.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">615</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">22</span> Systematic Discovery of Bacterial Toxins Against Plants Pathogens Fungi</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yaara%20Oppenheimer-Shaanan">Yaara Oppenheimer-Shaanan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nimrod%20Nachmias"> Nimrod Nachmias</a>, <a href="https://publications.waset.org/abstracts/search?q=Marina%20Campos%20Rocha"> Marina Campos Rocha</a>, <a href="https://publications.waset.org/abstracts/search?q=Neta%20Schlezinger"> Neta Schlezinger</a>, <a href="https://publications.waset.org/abstracts/search?q=Noam%20Dotan"> Noam Dotan</a>, <a href="https://publications.waset.org/abstracts/search?q=Asaf%20Levy"> Asaf Levy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fusarium oxysporum, a fungus that attacks a broad range of plants and can cause infections in humans, operates across different kingdoms. This pathogen encounters varied conditions, such as temperature, pH, and nutrient availability, in plant and human hosts. The Fusarium oxysporum species complex, pervasive in soils globally, can affect numerous plants, including key crops like tomatoes and bananas. Controlling Fusarium infections can involve biocontrol agents that hinder the growth of harmful strains. Our research developed a computational method to identify toxin domains within a vast number of microbial genomes, leading to the discovery of nine distinct toxins capable of killing bacteria and fungi, including Fusarium. These toxins appear to function as enzymes, causing significant damage to cellular structures, membranes and DNA. We explored biological control using bacteria that produce polymorphic toxins, finding that certain bacteria, non-pathogenic to plants, offer a safe biological alternative for Fusarium management, as they did not harm macrophage cells or C. elegans. Additionally, we elucidated the 3D structures of two toxins with their protective immunity proteins, revealing their function as unique DNases. These potent toxins are likely instrumental in microbial competition within plant ecosystems and could serve as biocontrol agents to mitigate Fusarium wilt and related diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microbial%20toxins" title="microbial toxins">microbial toxins</a>, <a href="https://publications.waset.org/abstracts/search?q=antifungal" title=" antifungal"> antifungal</a>, <a href="https://publications.waset.org/abstracts/search?q=Fusarium%20oxysporum" title=" Fusarium oxysporum"> Fusarium oxysporum</a>, <a href="https://publications.waset.org/abstracts/search?q=bacterial-fungal%20intreactions" title=" bacterial-fungal intreactions"> bacterial-fungal intreactions</a> </p> <a href="https://publications.waset.org/abstracts/183577/systematic-discovery-of-bacterial-toxins-against-plants-pathogens-fungi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183577.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">57</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">21</span> An MIPSSTWM-based Emergency Vehicle Routing Approach for Quick Response to Highway Incidents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siliang%20Luan">Siliang Luan</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhongtai%20Jiang"> Zhongtai Jiang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The risk of highway incidents is commonly recognized as a major concern for transportation authorities due to the hazardous consequences and negative influence. It is crucial to respond to these unpredictable events as soon as possible faced by emergency management decision makers. In this paper, we focus on path planning for emergency vehicles, one of the most significant processes to avoid congestion and reduce rescue time. A Mixed-Integer Linear Programming with Semi-Soft Time Windows Model (MIPSSTWM) is conducted to plan an optimal routing respectively considering the time consumption of arcs and nodes of the urban road network and the highway network, especially in developing countries with an enormous population. Here, the arcs indicate the road segments and the nodes include the intersections of the urban road network and the on-ramp and off-ramp of the highway networks. An attempt in this research has been made to develop a comprehensive and executive strategy for emergency vehicle routing in heavy traffic conditions. The proposed Cuckoo Search (CS) algorithm is designed by imitating obligate brood parasitic behaviors of cuckoos and Lévy Flights (LF) to solve this hard and combinatorial problem. Using a Chinese city as our case study, the numerical results demonstrate the approach we applied in this paper outperforms the previous method without considering the nodes of the road network for a real-world situation. Meanwhile, the accuracy and validity of the CS algorithm also show better performances than the traditional algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emergency%20vehicle" title="emergency vehicle">emergency vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=path%20planning" title=" path planning"> path planning</a>, <a href="https://publications.waset.org/abstracts/search?q=cs%20algorithm" title=" cs algorithm"> cs algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20traffic%20management%20and%20urban%20planning" title=" urban traffic management and urban planning"> urban traffic management and urban planning</a> </p> <a href="https://publications.waset.org/abstracts/156594/an-mipsstwm-based-emergency-vehicle-routing-approach-for-quick-response-to-highway-incidents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156594.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">80</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">20</span> Victim Witnesses of Human Trafficking: A Phenomenological Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jireh%20Reinor%20L.%20Vitto">Jireh Reinor L.

It utilized a qualitative phenomenological study design. Eighteen women, 15 to 46 years old, had experienced human trafficking (sex or labor trafficking), and with a filed case or not. An in-depth semi-structured, open-ended interview was employed to gather information. Guardians were also interviewed for triangulation purposes. Findings showed that the participants experienced fatigue and abuse for their physical aspect and gained negative feelings such as burdened, sad, scared (fear), stress, anger, trauma, depress and suicidal thoughts for their psychological aspect. For the spiritual aspect, the participants concluded to have enhanced spiritual life where they knew about God, became closer to God, and learned how to pray. They also faced challenges such as dysfunctional family, delinquent friends, exploitation, problems kept from the family, and poverty, which resulted in their becoming victims of human trafficking. To cope with the situation, they utilized family support, prayers, guts or courage (lakas ng loob), negotiation with their employer, and support from kababayans. Their practices and mechanisms to recover were the Blas Ople Center, rescue/entrapment operation, shelter, and embassy. After the incident, the participants shared that they earned to have thoughts of having a good life without going abroad/makabayan, knowledge of overseas Filipino workers, wise choice of friends, contentment, and value for the family. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=victim-witnesses" title="victim-witnesses">victim-witnesses</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20trafficking" title=" human trafficking"> human trafficking</a>, <a href="https://publications.waset.org/abstracts/search?q=lived%20experiences" title=" lived experiences"> lived experiences</a>, <a href="https://publications.waset.org/abstracts/search?q=challenges" title=" challenges"> challenges</a>, <a href="https://publications.waset.org/abstracts/search?q=coping%20strategies" title=" coping strategies"> coping strategies</a> </p> <a href="https://publications.waset.org/abstracts/134161/victim-witnesses-of-human-trafficking-a-phenomenological-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134161.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> A Corporate Social Responsibility Project to Improve the Democratization of Scientific Education in Brazil </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Denise%20Levy">Denise Levy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nuclear technology is part of our everyday life and its beneficial applications help to improve the quality of our lives. Nevertheless, in Brazil, most often the media and social networks tend to associate radiation to nuclear weapons and major accidents, and there is still great misunderstanding about the peaceful applications of nuclear science. The Educational Portal Radioatividades (Radioactivities) is a corporate social responsibility initiative that takes advantage of the growing impact of Internet to offer high quality scientific information for teachers and students throughout Brazil. This web-based initiative focusses on the positive applications of nuclear technology, presenting the several contributions of ionizing radiation in different contexts, such as nuclear medicine, agriculture techniques, food safety and electric power generation, proving nuclear technology as part of modern life and a must to improve the quality of our lifestyle. This educational project aims to contribute for democratization of scientific education and social inclusion, approaching society to scientific knowledge, promoting critical thinking and inspiring further reflections. The website offers a wide variety of ludic activities such as curiosities, interactive exercises and short courses. Moreover, teachers are offered free web-based material with full instructions to be developed in class. Since year 2013, the project has been developed and improved according to a comprehensive study about the realistic scenario of ICTs infrastructure in Brazilian schools and in full compliance with the best e-learning national and international recommendations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=information%20and%20communication%20technologies" title="information and communication technologies">information and communication technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20technology" title=" nuclear technology"> nuclear technology</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20communication" title=" science communication"> science communication</a>, <a href="https://publications.waset.org/abstracts/search?q=society%20and%20education" title=" society and education"> society and education</a> </p> <a href="https://publications.waset.org/abstracts/55420/a-corporate-social-responsibility-project-to-improve-the-democratization-of-scientific-education-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55420.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">326</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Delamination Fracture Toughness Benefits of Inter-Woven Plies in Composite Laminates Produced through Automated Fibre Placement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jayden%20Levy">Jayden Levy</a>, <a href="https://publications.waset.org/abstracts/search?q=Garth%20M.%20K.%20Pearce"> Garth M.

Termed ‘inter-weaving’, the method uses custom placement sequences of thermoset prepreg tows to distribute regular fibre link regions in traditionally clean ply interfaces. Inter-weaving’s impact on mode I delamination fracture toughness was evaluated experimentally through double cantilever beam tests (ASTM standard D5528-13) on [±15°]9 laminates made from Park Electrochemical Corp. E-752-LT 1/4” carbon fibre prepreg tape. Unwoven and inter-woven automated fibre placement samples were compared to those of traditional laminates produced from standard uni-directional plies of the same material system. Unwoven automated fibre placement laminates were found to suffer a mostly constant 3.5% decrease in mode I delamination fracture toughness compared to flat uni-directional plies. Inter-weaving caused significant local fracture toughness increases (up to 50%), though these were offset by a matching overall reduction. These positive and negative behaviours of inter-woven laminates were respectively found to be caused by fibre breakage and matrix deformation at inter-weave sites, and the 3D layering of inter-woven ply interfaces providing numerous paths of least resistance for crack propagation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AFP" title="AFP">AFP</a>, <a href="https://publications.waset.org/abstracts/search?q=automated%20fibre%20placement" title=" automated fibre placement"> automated fibre placement</a>, <a href="https://publications.waset.org/abstracts/search?q=delamination" title=" delamination"> delamination</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture%20toughness" title=" fracture toughness"> fracture toughness</a>, <a href="https://publications.waset.org/abstracts/search?q=inter-weaving" title=" inter-weaving"> inter-weaving</a> </p> <a href="https://publications.waset.org/abstracts/80136/delamination-fracture-toughness-benefits-of-inter-woven-plies-in-composite-laminates-produced-through-automated-fibre-placement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80136.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">184</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">17</span> Development the Potential of Parking Tax and Parking Retribution Revenues: Case Study in Bekasi City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ivan%20Yudianto">Ivan Yudianto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research objectives are to analyze the factors that impede the Parking Tax and Parking Retribution collection in Bekasi City Government, analyzing the factors that can increase local own revenue from the tax sector of parking tax and parking retribution, analyze monitoring the parking retribution collection by the Bekasi City Government, analyze strategies Bekasi City Government through the preparation of a roadmap and action plan to increase parking tax and parking retribution revenues.

Misinformation and common wrong beliefs confuse public’s perceptions and the scientific community is expected to offer a wider perspective on the benefits and risks resulting from ionizing radiation in everyday life. Attentive to the need of new approaches between science and society, the Nuclear Energy Museum, in northeast Brazil, is an initiative created to communicate the growing impact of the beneficial applications of nuclear technology in medicine, industry, agriculture and electric power generation. Providing accessible scientific information, the museum offers a rich learning environment, making use of different educational strategies, such as films, interactive panels and multimedia learning tools, which not only increase the enjoyment of visitors, but also maximize their learning potential. Developed according to modern active learning instructional strategies, multimedia materials are designed to present the increasingly role of nuclear science in modern life, transforming science education into a meaningful learning experience. In year 2016, nine different interactive computer-based activities were developed, presenting curiosities about ionizing radiation in different landmarks around the world, such as radiocarbon dating works in Egypt, nuclear power generation in France and X-radiography of famous paintings in Italy. Feedback surveys have reported a high level of visitors’ satisfaction, proving the high quality experience in learning nuclear science at the museum. The Nuclear Energy Museum is the first and, up to the present time, the only permanent museum in Brazil devoted entirely to nuclear science. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nuclear%20technology" title="nuclear technology">nuclear technology</a>, <a href="https://publications.waset.org/abstracts/search?q=multimedia%20learning%20tools" title=" multimedia learning tools"> multimedia learning tools</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20museum" title=" science museum"> science museum</a>, <a href="https://publications.waset.org/abstracts/search?q=society%20and%20education" title=" society and education"> society and education</a> </p> <a href="https://publications.waset.org/abstracts/55564/the-nuclear-energy-museum-in-brazil-creative-solutions-to-transform-science-education-into-meaningful-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55564.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">324</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">15</span> Modeling of Bipolar Charge Transport through Nanocomposite Films for Energy Storage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meng%20H.%20Lean">Meng H.

A 3D particle-in-cell model extends the classical electrical double layer representation to treat ferroelectric nanoparticles. Metal-polymer charge injection assumes Schottky emission and Fowler-Nordheim tunneling, migration through field-dependent Poole-Frenkel mobility, and recombination with Monte Carlo selection based on collision probability. A boundary integral equation method is used for solution of the Poisson equation coupled with a second-order predictor-corrector scheme for robust time integration of the equations of motion. The stability criterion of the explicit algorithm conforms to the Courant-Friedrichs-Levy limit. Trajectories for charge that make it through the film are curvilinear paths that meander through the interspaces. Results indicate that charge transport behavior depends on nanoparticle polarization with anti-parallel orientation showing the highest leakage conduction and lowest level of charge trapping in the interaction zone. Simulation prediction of a size range of 80 to 100 nm to minimize attachment and maximize conduction is validated by theory. Attached charge fractions go from 2.2% to 97% as nanofiller size is decreased from 150 nm to 60 nm. Computed conductivity of 0.4 x 1014 S/cm is in agreement with published data for plastics. Charge attachment is increased with spheroids due to the increase in surface area, and especially so for oblate spheroids showing the influence of larger cross-sections. Charge attachment to nanofillers and nanocrystallites increase with vol.% loading or degree of crystallinity, and saturate at about 40 vol.%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanocomposites" title="nanocomposites">nanocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofillers" title=" nanofillers"> nanofillers</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20double%20layer" title=" electrical double layer"> electrical double layer</a>, <a href="https://publications.waset.org/abstracts/search?q=bipolar%20charge%20transport" title=" bipolar charge transport"> bipolar charge transport</a> </p> <a href="https://publications.waset.org/abstracts/31221/modeling-of-bipolar-charge-transport-through-nanocomposite-films-for-energy-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31221.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">354</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">14</span> Vestibular Dysfunction in Post-Acute Sequelae of SARS-CoV-2 Infection: A Gait Analysis Pilot Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adar%20Pelah">Adar Pelah</a>, <a href="https://publications.waset.org/abstracts/search?q=Avraham%20Adelman"> Avraham Adelman</a>, <a href="https://publications.waset.org/abstracts/search?q=Amanda%20Balash"> Amanda Balash</a>, <a href="https://publications.waset.org/abstracts/search?q=Jake%20Mitchell"> Jake Mitchell</a>, <a href="https://publications.waset.org/abstracts/search?q=Mattan%20J.%20Pelah"> Mattan J.

This study utilized gait analysis to assess the potential vestibular effects of PASC on the presentation of gait anomalies. Materials and Methods: The study included 11 participants who tested positive for COVID-19, a mean of 2.8 months prior to gait testing (PP=11), and 8 control participants who did not test positive for COVID-19 (NP=8). Participants walked 7.5m at three self-selected speeds: ‘slow,’ ‘normal,’ and ‘fast.’ Mean walking speeds were determined for each speed and overall range from four laps on an instrumented walkway using video capture. Results: A Z-test at 0.05 significance was used for speed range, ‘normal’ and ‘fast’ at the lower tail, and for ‘slow’ at the higher tail. Average speeds (m/s) were: ‘slow’ (PP=0.709, NP=0.678), ‘normal’ (PP=1.141, NP=1.170), ‘fast’ (PP=1.529, NP=1.821), average range (PP=0.846, NP=1.143). Significant speed decreases between PP and NP were observed in ‘fast’ (-17.43%) and average range (-29.86%), while changes in ‘slow’ (+2.44%) and ‘normal’ (-4.39%) speeds were not significant. Conclusions: Long COVID is a recognized disability (Americans with Disabilities Act), and although it presents variably, dizziness, vertigo, and tinnitus are not uncommon in COVID-19 infection. These results suggest that potential inner-ear damage may persist and manifest in gait changes even after recovery from acute illness. Further research with a larger sample size may indicate the need for providers to consider PASC when diagnosing patients with vestibular dysfunction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gait%20analysis" title="gait analysis">gait analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=long-COVID" title=" long-COVID"> long-COVID</a>, <a href="https://publications.waset.org/abstracts/search?q=vestibular%20dysfunction" title=" vestibular dysfunction"> vestibular dysfunction</a>, <a href="https://publications.waset.org/abstracts/search?q=walking%20speed" title=" walking speed"> walking speed</a> </p> <a href="https://publications.waset.org/abstracts/163209/vestibular-dysfunction-in-post-acute-sequelae-of-sars-cov-2-infection-a-gait-analysis-pilot-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163209.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">125</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">13</span> Characterization of a Broad Range Antimicrobial Substance from Pseudozyma aphidis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raviv%20Harris">Raviv Harris</a>, <a href="https://publications.waset.org/abstracts/search?q=Maggie%20Levy"> Maggie Levy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Natural product-based pesticides may serve as an alternative to the traditional synthetic pesticides, which have a potentially damaging effect, both to human health and for the environment. Along with plants, microorganisms are a prospective source of such biological pesticides. A unique and active strain of P. aphidis (designated isolate L12, Israel 2004), an epiphytic and non-pathogenic basidiomycete yeast, was isolated in our lab from strawberry leaves. P. aphidis L12 secretions were found to inhibit broad range of plant pathogens. This work demonstrates that metabolites isolated from the biocontrol agent P. aphidis (isolate L12) can inhibit varied fungal and bacterial phytopathogens. Biologically active metabolites were extracted from P. aphidis biomass, using the organic solvent ethyl acetate. The antimicrobial activity of the extract was demonstrated, both in vitro and in planta. Using disk diffusion assays, the following inhibition zones were obtained: 43cm² for Pseudomonas syringae pv. tomato, 28.5cm² for Xanthomonas campestris pv. vesicatoria, 59cm² for Clavibacter michiganensis subsp. michiganensis, 34cm² for Erwinia amylovora and 34cm² for Agrobacterium tumefaciens. Additionally, strong inhibitory activity of the extract against fungi mycelial growth was established, with IC₅₀ values of 606µg ml⁻¹ for Botrytis cinerea, 221µg ml⁻¹ for Pythium spp., 519µg ml⁻¹ for Rhizoctonia solani, 455µg ml⁻¹ for Sclerotinia sclerotiorum, 2270µg ml⁻¹ for Fusarium oxysporum f. sp. lycopersici, and 2038µg ml⁻¹ for Alternaria alternata. The results of the in planta experiments demonstrated a dose-dependent reduction in disease infection. Significant inhibition of B. cinerea lesions on tomato plants was obtained when a spore suspension of this pathogen was treated with extract concentrations higher than 4.2mg ml⁻¹. Concentration of 7mg ml⁻¹ caused a reduction of over 95% in the lesion size of B. cinerea on tomato plants. The strong antimicrobial activity demonstrated both in vitro and in planta against varied phytopathogens, may indicate that the extracted antimicrobial metabolites have potential to serve as natural pesticides in the field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title="antimicrobial">antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20cinerea" title=" B. cinerea"> B. cinerea</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolites" title=" metabolites"> metabolites</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20pesticides" title=" natural pesticides"> natural pesticides</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20aphidis" title=" P. aphidis"> P. aphidis</a> </p> <a href="https://publications.waset.org/abstracts/71250/characterization-of-a-broad-range-antimicrobial-substance-from-pseudozyma-aphidis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71250.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">231</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">12</span> Educating the Educators: Interdisciplinary Approaches to Enhance Science Teaching</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Denise%20Levy">Denise Levy</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Lucia%20C.%20H.%20Villavicencio"> Anna Lucia C.

In addition to the basic curriculum, there must be included several transversal themes, which demand creative and innovative strategies to be arranged and integrated to traditional disciplines. In Brazil, nuclear science is still a controversial theme, and teachers themselves seem to be unaware of the issue, most often perpetuating prejudice, errors and misconceptions. This article presents the authors’ experience in the development of an interdisciplinary pedagogical proposal to include nuclear science in the basic curriculum, in a transversal and integrating way. The methodology applied was based on the analysis of several normative documents that define the requirements of essential learning, competences and skills of basic education for all schools in Brazil. The didactic materials and resources were developed according to the best practices to improve learning processes privileging constructivist educational techniques, with emphasis on active learning process, collaborative learning and learning through research. The material consists of an illustrated book for students, a book for teachers and a manual with activities that can articulate nuclear science to different disciplines: Portuguese, mathematics, science, art, English, history and geography. The content counts on high scientific rigor and articulate nuclear technology with topics of interest to society in the most diverse spheres, such as food supply, public health, food safety and foreign trade. Moreover, this pedagogical proposal takes advantage of the potential value of digital technologies, implementing QR codes that excite and challenge students of all ages, improving interaction and engagement. The expected results include the education of the educators for nuclear science communication in a transversal and integrating way, demystifying nuclear technology in a contextualized and significant approach. It is expected that the interdisciplinary pedagogical proposal contributes to improving attitudes towards knowledge construction, privileging reconstructive questioning, fostering a culture of systematic curiosity and encouraging critical thinking skills. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=science%20education" title="science education">science education</a>, <a href="https://publications.waset.org/abstracts/search?q=interdisciplinary%20learning" title=" interdisciplinary learning"> interdisciplinary learning</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20science" title=" nuclear science"> nuclear science</a>, <a href="https://publications.waset.org/abstracts/search?q=scientific%20literacy" title=" scientific literacy"> scientific literacy</a> </p> <a href="https://publications.waset.org/abstracts/110175/educating-the-educators-interdisciplinary-approaches-to-enhance-science-teaching" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110175.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">133</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">11</span> Web-Based Tools to Increase Public Understanding of Nuclear Technology and Food Irradiation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Denise%20Levy">Denise Levy</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Lucia%20C.%20H.%20Villavicencio"> Anna Lucia C.

Moreover, the process helps to inhibit sprouting and delay ripening, extending fresh fruits and vegetables shelf-life. Nevertheless, most Brazilian consumers seem to misunderstand the difference between irradiated food and radioactive food and the general public has major concerns about the negative health effects and environmental contamination. Society´s judgment and decision making are directly linked to perceived benefits and risks. The web-based project entitled ‘Scientific information about food irradiation: Internet as a tool to approach science and society’ was created by the Nuclear and Energetic Research Institute (IPEN), in order to offer an interdisciplinary approach to science education, integrating economic, ethical, social and political aspects of food irradiation. This project takes into account that, misinformation and unfounded preconceived ideas impact heavily on the acceptance of irradiated food and purchase intention by the Brazilian consumer. Taking advantage of the potential value of the Internet to enhance communication and education among general public, a research study was carried out regarding the possibilities and trends of Information and Communication Technologies among the Brazilian population. The content includes concepts, definitions and Frequently Asked Questions (FAQ) about processes, safety, advantages, limitations and the possibilities of food irradiation, including health issues, as well as its impacts on the environment. The project counts on eight self-instructional interactive web courses, situating scientific content in relevant social contexts in order to encourage self-learning and further reflections. Communication is a must to improve public understanding of science. The use of information technology for quality scientific divulgation shall contribute greatly to provide information throughout the country, spreading information to as many people as possible, minimizing geographic distances and stimulating communication and development. <p class="card-text"><strong>Keywords:</strong> <a
