The study conducted in this paper examines the influence of temperature on the performance of the permeant magnet linear generator, an integral and pivotal component within the system. This research places particular emphasis on the Neodymium Iron Boron (NdFeB) permanent magnet, which serves as a source of magnetic field for the linear generator. In this study, an internal combustion engine that tends to produce heat is connected to a generator. Considering the temperatures rise from both the combustion process and the thermal contributions of current-carrying conductors and frictional forces. Utilizing Computational Fluid Dynamics (CFD) method, a thermal model of the (NdFeB) magnet within the linear generator is constructed and analyzed. Furthermore, the temperature field is examined to ensure that the linear generator operates under stable conditions without the risk of demagnetization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=free%20piston%20engine" title="free piston engine">free piston engine</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet" title=" permanent magnet"> permanent magnet</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20generator" title=" linear generator"> linear generator</a>, <a href="https://publications.waset.org/abstracts/search?q=demagnetization" title=" demagnetization"> demagnetization</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/185409/temperature-rises-characteristics-of-distinct-double-sided-flat-permanent-magnet-linear-generator-for-free-piston-engines-for-hybrid-vehicles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185409.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">56</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">907</span> New Method for the Synthesis of Different Pyrroloquinazolinoquinolin Alkaloids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulkareem%20M.%20Hamid">Abdulkareem M.

All luotonins have shown promising cytotoxicities towards selected human cancer cell lines, especially against leukemia P-388 cells. Luotonin A is the most active one, with its activity stemming from topoisomerase I-dependent DNA-cleavage. Such intriguing biological activities and unique structures have led not only to the development of synthetic methods for the efficient synthesis of these compounds, but also to interest in structural modifications for improving the biological properties.

This study aims to determine what percentage of all chemistry students selected teaching as a career. There is a lack of science teachers (especially physics and chemistry) in Poland, and there is limited research on students' choices and professional preferences. At the Faculty of Chemistry of the Adam Mickiewicz University in the academic year 2019/2020, changes were introduced to the study program resulting from legal regulations and as part of the funds raised from the project "Teacher - competent practitioner, supervisor, expert", No. POWR.03.01.00-00-KN40/18. The aim of the study was to determine how many first-cycle and second-cycle studies students declare the teaching profession as a career. In the case of first-cycle studies students, 9.5% of respondents choose the teaching profession and 9.2% of second-cycle studies students. It was found that the number of students who chose the teacher preparation programme at Faculty of Chemistry of the Adam Mickiewicz University has decreased since 5 years. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=faculty%20of%20chemistry" title="faculty of chemistry">faculty of chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=Adam%20Mickiewicz%20University" title=" Adam Mickiewicz University"> Adam Mickiewicz University</a>, <a href="https://publications.waset.org/abstracts/search?q=professional%20ambitions" title=" professional ambitions"> professional ambitions</a>, <a href="https://publications.waset.org/abstracts/search?q=students" title=" students"> students</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher" title=" teacher"> teacher</a> </p> <a href="https://publications.waset.org/abstracts/121371/professional-ambitions-of-students-of-faculty-of-chemistry-adam-mickiewicz-university-in-the-context-of-teaching-profession" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121371.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">905</span> Exploring the Quest for Centralized Identity in Mohsin Hamid's "The Last White Man": Post-Apocalyptic Transformations and Societal Reconfigurations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kashifa%20Khalid">Kashifa Khalid</a>, <a href="https://publications.waset.org/abstracts/search?q=Eesham%20Fatima"> Eesham Fatima</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to analyze the loss of identity and its impact on one’s life in ‘The Last White Man’ by Mohsin Hamid. The theory of Alienation Effect by Bertolt Brecht has been applied to the text as Hamid offers the readers a unique perspective, alluding to significant themes like identity, race, and death. The aspects of defamiliarization align impeccably with the plot, as existence and the corresponding concept of identity seem to have dissolved into utter chaos. This extends from the unexplained transformation to the way the entire world unravels from its general norm into a dystopian mayhem. The characters, starting with the protagonist Anders, have lost their center. One’s own self transforms into the ‘other,’ and the struggle is to get refamiliarized with one’s own self. Alienation and isolation only rise as the construct of race and identity is taken apart brick by brick, ironically at its own pace as many new realities are blown to bits. The inseparable relationship between identity and grief under the ever-looming cloud of ‘death’ is studied in detail. The theoretical framework and thematic aspects harmonize in accordance with the writing style put forth by Hamid, tying all the loose ends together. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alienation" title="alienation">alienation</a>, <a href="https://publications.waset.org/abstracts/search?q=chaos" title=" chaos"> chaos</a>, <a href="https://publications.waset.org/abstracts/search?q=identity" title=" identity"> identity</a>, <a href="https://publications.waset.org/abstracts/search?q=transformation" title=" transformation"> transformation</a> </p> <a href="https://publications.waset.org/abstracts/186822/exploring-the-quest-for-centralized-identity-in-mohsin-hamids-the-last-white-man-post-apocalyptic-transformations-and-societal-reconfigurations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186822.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">44</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">904</span> Parabolic Impact Law of High Frequency Exchanges on Price Formation in Commodities Market</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Maiza">L.

Food waste decomposition process was conducted for 14 days and kept at 20°C and 30°C in self-made bioreactor. VOCs emissions from both samples were collected at different stages of decomposition starting at day 0, day 1, day 3, day 5, day 7, day 10, day 12 and day 14. It was analyzed using TD-GC/MS. Findings showed that various VOCs were released during decomposition of food waste. Compounds produced were influenced by time, temperature and the physico-chemical characteristics of the compounds. The most abundant compound released was dimethyl disulfide. Potential health risk of exposure to this compound is represented by hazard ratio, HR, calculated at 1.6 x 1011. Since HR equal to or less than 1.0 is considered negligible risk, this indicates that the compound posed a potential risk to human health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=volatile%20organic%20compounds" title="volatile organic compounds">volatile organic compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=decomposition%20process" title=" decomposition process"> decomposition process</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20waste" title=" food waste"> food waste</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20risk" title=" health risk"> health risk</a> </p> <a href="https://publications.waset.org/abstracts/39703/volatile-organic-compounds-from-decomposition-of-local-food-waste-and-potential-health-risk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39703.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">520</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">902</span> The Extent of Big Data Analysis by the External Auditors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iyad%20Ismail">Iyad Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Fathilatul%20Abdul%20Hamid"> Fathilatul Abdul Hamid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research was mainly investigated to recognize the extent of big data analysis by external auditors.

Due to the unpredicted and intermittent nature of RES, the hybrid renewable energy system (HRES) is the best solution to complement the nature of the respective sources, and the combination of the wind and solar energy is rapidly gaining popularity. The significant challenges on the operation and planning of the grid system with a high HRES penetration has become an important subject since the location of HRES plant give impact towards the existing system. This paper aims to propose the location of the grid connected Wind-PV hybrid plant (WPHP) based on load flow and voltage stability indices study. Several case studies are carried out using IEEE 14 bus system, and the system is modeled and tested in DigSILENT PowerFactory. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrid%20renewable%20energy%20system" title="hybrid renewable energy system">hybrid renewable energy system</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20farm" title=" wind farm"> wind farm</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20system" title=" photovoltaic system"> photovoltaic system</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20stability%20and%20load%20flow" title=" voltage stability and load flow"> voltage stability and load flow</a> </p> <a href="https://publications.waset.org/abstracts/60502/proposed-location-of-grid-connected-wind-pv-hybrid-system-based-on-load-flow-and-voltage-stability-indices-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60502.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">315</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">899</span> “Thou Shalt Surely Die”: A Game Theory Analysis of the Book of Genesis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bo%20Kampmann%20Walther">Bo Kampmann Walther</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This essay examines the narratives of the Book of Genesis through the lens of game theory, a mathematical framework for analyzing strategic interactions among rational actors. By treating key figures in Genesis as players in a game, this analysis sheds light on their decisions and the resulting consequences. Focusing primarily on the story of Adam and Eve, the essay utilizes concepts such as game state, saddle point, optimal strategy, and Nash equilibrium to explore the dynamics at play and scrutinize the existence of two kinds of game rules in Genesis: one being global and post-Fall oriented, the other being local and relegated to life in the Garden. The serpent's intervention and the subsequent actions of Adam and Eve are modeled as strategic moves, revealing the complexities and shifts in the game state from harmony in Eden to a world marked by toil and mortality post-Fall. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=game%20theory" title="game theory">game theory</a>, <a href="https://publications.waset.org/abstracts/search?q=Genesis" title=" Genesis"> Genesis</a>, <a href="https://publications.waset.org/abstracts/search?q=strategy" title=" strategy"> strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=saddle%20point" title=" saddle point"> saddle point</a>, <a href="https://publications.waset.org/abstracts/search?q=nash%20equilibrium" title=" nash equilibrium"> nash equilibrium</a>, <a href="https://publications.waset.org/abstracts/search?q=New%20Game%20State" title=" New Game State"> New Game State</a> </p> <a href="https://publications.waset.org/abstracts/186277/thou-shalt-surely-die-a-game-theory-analysis-of-the-book-of-genesis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186277.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">44</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">898</span> Damage Assessment of Current Facades in Turkey throughout the Seismic Actions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B%C3%BC%C5%9Fra%20Elibol">Büşra Elibol</a>, <a href="https://publications.waset.org/abstracts/search?q=%C4%B0smail%20Sait%20Soyer"> İsmail Sait Soyer</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Farrokh%20Ghatte"> Hamid Farrokh Ghatte</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The continuity of the structural and non-structural elements within the envelope of the buildings is one of the fundamental factors in buildings during seismic actions. This investigation aims to make a comparison between Van and İzmir earthquakes in terms of damage assessment of the various facades. A strong earthquake (magnitude 7.2) struck the city of Van in the east of Turkey on 23 October 2011, and similarly, another strong earthquake struck the city of İzmir (magnitude 6.9) in Turkey on 30 October 2020. This paper presents the damage assessment of the current facade systems from multi-story buildings in Van and İzmir, Turkey. This investigation covers the buildings greater than three stories in height, excluding most unreinforced masonry facades. Regarding a building that can have more than one facade system, any of the facade systems are considered individually. Observation of different kinds of damages in the facade is discussed and represented in terms of its performance level throughout the seismic actions. Furthermore, presenting the standard design guidelines (i.e., Turkish seismic design code) is required not only for designers but also for installers of facade systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damage" title="damage">damage</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake" title=" earthquake"> earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=facade" title=" facade"> facade</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20element" title=" structural element"> structural element</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20action" title=" seismic action"> seismic action</a> </p> <a href="https://publications.waset.org/abstracts/151071/damage-assessment-of-current-facades-in-turkey-throughout-the-seismic-actions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151071.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">161</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">897</span> Energy Scenarios for Greater Kampala Metropolitan Area towards a Sustainable 2050: A TIMES-VEDA Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kimuli%20Ismail">Kimuli Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Lubwama"> Michael Lubwama</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Baptist%20Kirabira"> John Baptist Kirabira</a>, <a href="https://publications.waset.org/abstracts/search?q=Adam%20Sebbit"> Adam Sebbit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study develops 4 energy scenarios for Greater Kampala Metropolitan Area (GKMA). GKMA is Uganda’s capital with a population of 4.1million and a GDP growth rate of 5.8 with a nonsustainable energy management system. The study uses TIMES-VEDA to examine the energy impacts of business as usual (BAU), Kabejja, Carbon-Tax, and Lutta scenarios in commercial, industrial, transportation, residential, agricultural, and electricity generation activities. BAU is the baseline scenario with limited CO2 emissions restrictions against which Kabejja with 20% CO2 emissions restriction, a carbon tax of $100/ton imposed in 2050 for Carbon-Tax scenario, and Lutta with 95% CO2 emissions restriction is made. The analysis suggests that if the current policy trends continue as BAU, consumption would increase from 139.6PJ to 497.42PJ and CO2 emissions will increase from 4.6mtns to 7mtns. However, consumption would decrease by 2.3% in Kabejja, 3.4% in Carbon-Tax, and 3.3 % in Lutta compared to BAU. The CO2 emissions would decrease by 8.57% in Kabejja, 55.14% in Carbon-Tax, and 60% in Lutta compared to BAU. Sustainability is achievable when low-carbon electricity is increased by 53.68% in the EMS, and setting up an electrified Kampala metro. The study recommends Lutta as the sustainable pathway to a lowcarbon 2050. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sustainability" title="Sustainability">Sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=Scenario%20Plannnig" title=" Scenario Plannnig"> Scenario Plannnig</a>, <a href="https://publications.waset.org/abstracts/search?q=Times-Veda%20Modelling" title=" Times-Veda Modelling"> Times-Veda Modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=Energy%20Policy%20Development" title=" Energy Policy Development"> Energy Policy Development</a> </p> <a href="https://publications.waset.org/abstracts/161661/energy-scenarios-for-greater-kampala-metropolitan-area-towards-a-sustainable-2050-a-times-veda-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161661.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">69</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">896</span> Intellectual Telepathy between Arabs and Pashtuns; Study of Their Proverbs as a Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shams%20Ul%20Hussain%20Zaheer">Shams Ul Hussain Zaheer</a>, <a href="https://publications.waset.org/abstracts/search?q=Bibi%20Alia"> Bibi Alia</a>, <a href="https://publications.waset.org/abstracts/search?q=Shehla%20Shams"> Shehla Shams</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the creation of human beings, almost all of them are blessed with the award of the power of expression, and this series starts from the life of Adam (A.S) in Paradise when he was blesses with language and knowledge and given priority upon the Angels. Later on, when the population spread and many other languages came into being, the method of the different people of different regions remained various. And when the Arabic was formed as a language after Ismail (A.S) and his sons spread in the gulf area, the words adopted from other gulf languages also became a part of this new language with it immense. Beside this, the tone of expression in other areas of the word was different, but the incidents, norms of bad and good, parameters for like and dislike, thinking styles, and rules of good and bad governance with social values remained round about the same. People practiced their lives according to the set norms everywhere in the world. Especially the two built, i.e., Hijaz and Khurasan, wherein Arabs and Pashtun accordingly were dwelling; it seems that their social values were much closed to each other. These norms reflect in various kinds of literature of both of the nations, but this article deals in with their proverbs specifically. This article discusses the intellectual telepathic between them in a research way. And put the defined similarities and dissimilarities between both in the proverb. And it also draws a sketch in front of readers that how the thinking and expression styles remains same in humans.

The optical properties of the Ge<sub>1-x</sub>Mn<sub>x</sub>Te thin films with different thicknesses are determined by analyzing the transmittance and reflectance data. The energy band gaps of the amorphous Mn-doped GeTe thin films with different thicknesses were calculated. The obtained results demonstrated that the energy band gap values of the amorphous films are quite different and they are dependent on the films thicknesses. The extinction coefficients of amorphous Mn-doped GeTe thin films as function of wavelength for different thicknesses were measured. The results showed that the extinction coefficients of all films are varying inversely with their optical transmission. Moreover, the results emphasis that, not only the microstructure, electrical and magnetic properties of Mn doped GeTe thin films vary with the films thicknesses but also the optical properties differ with the film thickness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phase%20change%20magnetic%20materials" title="phase change magnetic materials">phase change magnetic materials</a>, <a href="https://publications.waset.org/abstracts/search?q=transmittance" title=" transmittance"> transmittance</a>, <a href="https://publications.waset.org/abstracts/search?q=absorbance" title=" absorbance"> absorbance</a>, <a href="https://publications.waset.org/abstracts/search?q=extinction%20coefficients" title=" extinction coefficients"> extinction coefficients</a> </p> <a href="https://publications.waset.org/abstracts/48213/the-effect-of-the-deposition-parameters-on-the-microstructural-and-optical-properties-of-mn-doped-gete-chalcogenide-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48213.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">894</span> Minority Rights in Islamic Law (Sharia) and International Law Protection Mechanisms in the Region Kurdistan of Iraq</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ardawan%20Mustafa%20Ismail">Ardawan Mustafa Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Rebaz%20Sdiq%20Ismail"> Rebaz Sdiq Ismail</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The subject of minorities takes an exceptional importance at all levels, around the world, especially those whose population is composed of many nationalities, and this subject became a very affective part in every country for its security, entity and stability, such as the nationality, religion or culture, as a result of internal factors and external influences, and at the same time it became clear that enslaving minorities had become a matter of reality.

This research will examine, for the first time in the literature, the motivation behind suboptimal decisions due to uncertainty by subjecting Adam Smith’s and Jeremy Bentham’s assumptions about the nature of the actions that lead to satisficing behavior, in order to clarify the theoretical background of a “consumption-based satisfactory time” concept. The contribution of this paper with respect to the existing literature is threefold: Firstly, it is showed in this paper that Adam Smith’s uncertainty is related to the problem of the constancy of ideas and not related directly to beliefs. Secondly, possessions, as in Jeremy Bentham’s oeuvre, are assumed to be just as pleasing, as protecting and improving the actual or expected quality of life, so long as they reduce any displeasure due to the undesired outcomes of uncertainty. Finally, each consumption decision incurs its own satisfactory time period, owed to not feeling hungry, being healthy, not having transportation…etc. This reveals that the level of satisfaction is indeed a behavioral phenomenon where its value would depend on the simultaneous satisfaction derived from all activities. <p class="card-text"><strong>Keywords:</strong> <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=idea%20and%20belief" title=" idea and belief"> idea and belief</a>, <a href="https://publications.waset.org/abstracts/search?q=satisficing" title=" satisficing"> satisficing</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty" title=" uncertainty"> uncertainty</a> </p> <a href="https://publications.waset.org/abstracts/30199/theoretical-appraisal-of-satisfactory-decision-uncertainty-evolutionary-ideas-and-beliefs-satisfactory-time-use" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30199.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">286</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">891</span> Holy Kabah and Holy Mosque: The Journey of Spiritual, Mystical and Social Ascension of Two Slaves of Ethiopia to Represent the Two Holiest Symbols of Islam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zawahir%20Siddique">Zawahir Siddique</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper explores the philosophical, spiritual, and mystical dimensions of the glorified journey of Hajira and Bilal. The black Ethiopian slave Hajira’s skirt was chosen to cover the first house of God on earth. Hajira was chosen by God as the embodiment of love and submission. The philosophy behind her migration with her child Ismail and wandering between Safa and Marwa in search of water that eventually gushed forth from the feet of Ismail and how God gifted Hajira, Ismail, and the entire humanity with Zamzam needs to be explored. Every year over two million pilgrims assemble and circumambulate around the Holy Kabah during Hajj, and every day, millions of Muslims pray, riveting their faith around Kabah. The significance and mysticism of the central figure of Hajira deserve due attention. Several eras later, the most blessed personality of humanity, Prophet Muhammad, elevated another Ethiopian Slave to the highest honor in the first Mosque of the Prophet of Islam in Medina. The purity of his heart and spiritually captivating voice of Bilal was preferred over his pre-Islamic social status. When the companions of the Prophet questioned the diction and pronunciation of 'SHEEN' by Bilal owing to his African origin, the Prophet immediately corrected them, justifying the purity of Bilal’s heart mattered more and hence Bilal’s 'SEEN' was heard as 'SHEEN' by God Almighty. The journey of Bilal to Islam and his pious and devoted contributions to Islam in the light of spirituality, mysticism, and social reforms are also explored further in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=philosophy" title="philosophy">philosophy</a>, <a href="https://publications.waset.org/abstracts/search?q=spirituality" title=" spirituality"> spirituality</a>, <a href="https://publications.waset.org/abstracts/search?q=mysticism" title=" mysticism"> mysticism</a>, <a href="https://publications.waset.org/abstracts/search?q=Hajira" title=" Hajira"> Hajira</a>, <a href="https://publications.waset.org/abstracts/search?q=Bilal" title=" Bilal"> Bilal</a> </p> <a href="https://publications.waset.org/abstracts/128902/holy-kabah-and-holy-mosque-the-journey-of-spiritual-mystical-and-social-ascension-of-two-slaves-of-ethiopia-to-represent-the-two-holiest-symbols-of-islam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128902.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">179</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">890</span> Prediction of the Aerodynamic Stall of a Helicopter’s Main Rotor Using a Computational Fluid Dynamics Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Assel%20Thami%20Lahlou">Assel Thami Lahlou</a>, <a href="https://publications.waset.org/abstracts/search?q=Soufiane%20Stouti"> Soufiane Stouti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Lagrat"> Ismail Lagrat</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Mounir"> Hamid Mounir</a>, <a href="https://publications.waset.org/abstracts/search?q=Oussama%20Bouazaoui"> Oussama Bouazaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this research work is to predict the helicopter from stalling by finding the minimum and maximum values that the pitch angle can take in order to fly in a hover state condition. The stall of a helicopter in hover occurs when the pitch angle is too small to generate the thrust required to support its weight or when the critical angle of attack that gives maximum lift is reached or exceeded. In order to find the minimum pitch angle, a 3D CFD simulation was done in this work using ANSYS FLUENT as the CFD solver. We started with a small value of the pitch angle θ, and we kept increasing its value until we found the thrust coefficient required to fly in a hover state and support the weight of the helicopter. For the CFD analysis, the Multiple Reference Frame (MRF) method with k-ε turbulent model was used to study the 3D flow around the rotor for θmin. On the other hand, a 2D simulation of the airfoil NACA 0012 was executed with a velocity inlet Vin=ΩR/2 to visualize the flow at the location span R/2 of the disk rotor using the Spallart-Allmaras turbulent model. Finding the critical angle of attack at this position will give us the ability to predict the stall in hover flight. The results obtained will be exposed later in the article. This study was so useful in analyzing the limitations of the helicopter’s main rotor and thus, in predicting accidents that can lead to a lot of damage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamic" title="aerodynamic">aerodynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=helicopter" title=" helicopter"> helicopter</a>, <a href="https://publications.waset.org/abstracts/search?q=stall" title=" stall"> stall</a>, <a href="https://publications.waset.org/abstracts/search?q=blades" title=" blades"> blades</a>, <a href="https://publications.waset.org/abstracts/search?q=main%20rotor" title=" main rotor"> main rotor</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20pitch%20angle" title=" minimum pitch angle"> minimum pitch angle</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20pitch%20angle" title=" maximum pitch angle"> maximum pitch angle</a> </p> <a href="https://publications.waset.org/abstracts/186086/prediction-of-the-aerodynamic-stall-of-a-helicopters-main-rotor-using-a-computational-fluid-dynamics-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186086.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">889</span> Exposing Latent Fingermarks on Problematic Metal Surfaces Using Time of Flight Secondary Ion Mass Spectroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tshaiya%20Devi%20Thandauthapani">Tshaiya Devi Thandauthapani</a>, <a href="https://publications.waset.org/abstracts/search?q=Adam%20J.%20Reeve"> Adam J.

However, visualising latent (hidden) fingermarks can be difficult, and the correct choice of techniques is essential to develop and preserve any fingermarks that might be present. Knives, firearms and other metal weapons have proven to be challenging substrates (stainless steel in particular) from which to reliably obtain fingermarks. In this study, time of flight secondary ion mass spectroscopy (ToF-SIMS) was used to image fingermarks on metal surfaces. This technique was compared to a conventional superglue based fuming technique that was accompanied by a series of contrast enhancing dyes (basic yellow 40 (BY40), crystal violet (CV) and Sudan black (SB)) on three different metal surfaces. The conventional techniques showed little to no evidence of fingermarks being present on the metal surfaces after a few days. However, ToF-SIMS images revealed fingermarks on the same and similar substrates with an exceptional level of detail demonstrating clear ridge definition as well as detail about sweat pore position and shape, that persist for over 26 days after deposition when the samples were stored under ambient conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conventional%20techniques" title="conventional techniques">conventional techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=latent%20fingermarks" title=" latent fingermarks"> latent fingermarks</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20substrates" title=" metal substrates"> metal substrates</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20of%20flight%20secondary%20ion%20mass%20spectroscopy" title=" time of flight secondary ion mass spectroscopy "> time of flight secondary ion mass spectroscopy </a> </p> <a href="https://publications.waset.org/abstracts/97702/exposing-latent-fingermarks-on-problematic-metal-surfaces-using-time-of-flight-secondary-ion-mass-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97702.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">164</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">888</span> Metaphorical Perceptions of Middle School Students regarding Computer Games</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Celik">Ismail Celik</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Sahin"> Ismail Sahin</a>, <a href="https://publications.waset.org/abstracts/search?q=Fetah%20Eren"> Fetah Eren</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The computer, among the most important inventions of the twentieth century, has become an increasingly important component in our everyday lives. Computer games also have become increasingly popular among people day-by-day, owing to their features based on realistic virtual environments, audio and visual features, and the roles they offer players. In the present study, the metaphors students have for computer games are investigated, as well as an effort to fill the gap in the literature. Students were asked to complete the sentence—‘Computer game is like/similar to….because….’— to determine the middle school students’ metaphorical images of the concept for ‘computer game’. The metaphors created by the students were grouped in six categories, based on the source of the metaphor. These categories were ordered as ‘computer game as a means of entertainment’, ‘computer game as a beneficial means’, ‘computer game as a basic need’, ‘computer game as a source of evil’, ‘computer game as a means of withdrawal’, and ‘computer game as a source of addiction’, according to the number of metaphors they included. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer%20game" title="computer game">computer game</a>, <a href="https://publications.waset.org/abstracts/search?q=metaphor" title=" metaphor"> metaphor</a>, <a href="https://publications.waset.org/abstracts/search?q=middle%20school%20students" title=" middle school students"> middle school students</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20environments" title=" virtual environments"> virtual environments</a> </p> <a href="https://publications.waset.org/abstracts/11784/metaphorical-perceptions-of-middle-school-students-regarding-computer-games" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11784.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">535</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">887</span> Designing an Online Case-Based Library for Technology Integration in Teacher Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Tevfik%20Hebebci">Mustafa Tevfik Hebebci</a>, <a href="https://publications.waset.org/abstracts/search?q=Sirin%20Kucuk"> Sirin Kucuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Celik"> Ismail Celik</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Oguz%20Akturk"> A.

The obtained results showed that the concentrations of investigated metals are represented in the following sequence; For Gulf of Aqaba sediments Fe > Mn > Zn > Pb > Cr > Ni > Cu > Cd. While for Gulf of Suez Sediments Fe > Mn > Pb > Zn > Cu > Cr > Ni > Cd. The degree of surface sediment contamination using Geo-accumulation index (I geo) and Metal Pollution Index (MPI) was computed. Higher MPI values were observed at the sites III (Nama Bay) and VIII (Rex Beach). According to Sediment quality guidelines (SQGs) approach, Pb and Cu in the gulf of Suez at station IX (Kabanon Beach) had probably adverse ecological effects to marine organisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal" title="heavy metal">heavy metal</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20risk" title=" environmental risk"> environmental risk</a>, <a href="https://publications.waset.org/abstracts/search?q=Suez%20gulf" title=" Suez gulf"> Suez gulf</a>, <a href="https://publications.waset.org/abstracts/search?q=Aqaba%20gulf" title=" Aqaba gulf"> Aqaba gulf</a> </p> <a href="https://publications.waset.org/abstracts/62062/heavy-metal-contamination-and-environmental-risk-in-surface-sediments-along-the-coasts-of-suez-and-aqaba-gulfs-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62062.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">443</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">885</span> Antimicrobial, Antioxidant Activities and Phytochemical Screening of Five Species from Acacia Used in Sudanese Ethnomedicine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hajir%20Abdllha">Hajir Abdllha</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Mohamed"> Alaa Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Khansa%20Almoniem"> Khansa Almoniem</a>, <a href="https://publications.waset.org/abstracts/search?q=Naga%20Adam"> Naga Adam</a>, <a href="https://publications.waset.org/abstracts/search?q=Wdeea%20Alhaadi"> Wdeea Alhaadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Elshikh"> Ahmed Elshikh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Ali"> Ahmed Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Makuar"> Ismail Makuar</a>, <a href="https://publications.waset.org/abstracts/search?q=Anas%20Elnazeer"> Anas Elnazeer</a>, <a href="https://publications.waset.org/abstracts/search?q=Nagat%20Elrofaei"> Nagat Elrofaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Samir%20Abdoelftah"> Samir Abdoelftah</a>, <a href="https://publications.waset.org/abstracts/search?q=Monier%20Hemidan"> Monier Hemidan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study was designed to investigate antimicrobial, and antioxidant activities of five species from Acacia (Acacia albidia, Acacia mellifera, Acacia nubica, Acacia seyal var. seyal and Acacia tortilis).

Another important line of research of the past decade in continuous optimization is the adaptive algorithms such as AdaGrad, that dynamically adjust the (possibly coordinate-wise) learning rate to past gradients and thereby adapt to the geometry of the objective function. Variants such as RMSprop and Adam demonstrate outstanding practical performance that have contributed to the success of deep learning. In this work, we present AdaLVR, which combines the AdaGrad algorithm with loopless variance-reduced gradient estimators such as SAGA or L-SVRG that benefits from a straightforward construction and a streamlined analysis. We assess that AdaLVR inherits both good convergence properties from VR methods and the adaptive nature of AdaGrad: in the case of L-smooth convex functions we establish a gradient complexity of O(n + (L + √ nL)/ε) without prior knowledge of L. Numerical experiments demonstrate the superiority of AdaLVR over state-of-the-art methods. Moreover, we empirically show that the RMSprop and Adam algorithm combined with variance-reduced gradients estimators achieve even faster convergence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=convex%20optimization" title="convex optimization">convex optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=variance%20reduction" title=" variance reduction"> variance reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20algorithms" title=" adaptive algorithms"> adaptive algorithms</a>, <a href="https://publications.waset.org/abstracts/search?q=loopless" title=" loopless"> loopless</a> </p> <a href="https://publications.waset.org/abstracts/182407/finite-sum-optimization-adaptivity-to-smoothness-and-loopless-variance-reduction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182407.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">71</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">882</span> Distribution and Densities of Anopheles Mosquito in El Obied Town, Sudan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adam%20Musa%20Adam%20Eissa">Adam Musa Adam Eissa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Environmental and weather changes especially rainfall affects the distribution and densities of mosquitoes. This work was carried out to study the distribution and densities of mosquitoes adults and larvae in a total of five selected stations in El Obied Town. A cross-sectional survey of Anopheline mosquito larval habitats was conducted. The survey was conducted during the dry season (January 2013). Larvae were collected by using the standard dipping technique, while adult stages were collected by rearing larvae in cage, because the density of adults Anopheles mosquito per room was zero by using spray sheet method by using Permethrin pesticide 25%E.C, during the study period. The results revealed that (2347) Anopheline mosquito larvae were found and collected from only one station. All of which (2347) larvae (100%) were classified as probably Anopheles Squamosus. The study also showed that, a number of 81 adults (100%) Anopheline mosquito were classified as probably Anopheles Squamosus. Anopheles Squamosus were found only in the shallow pond water habitat in Alrahma west area of El Obied, the mean Anopheline density in the study area for larvae was 0.313 per dip while the mean density of adult was 0 per room. The high mosquito larval density in Alrahma west area indicated that, this part of El Obied Town is at risk of mosquito-borne diseases including malaria. This study recommended to apply the control program against mosquito at this part of the Town. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anopheles" title="anopheles">anopheles</a>, <a href="https://publications.waset.org/abstracts/search?q=squamosus" title=" squamosus"> squamosus</a>, <a href="https://publications.waset.org/abstracts/search?q=Alrahma" title=" Alrahma"> Alrahma</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution" title=" distribution"> distribution</a> </p> <a href="https://publications.waset.org/abstracts/76461/distribution-and-densities-of-anopheles-mosquito-in-el-obied-town-sudan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76461.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">285</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">881</span> Mutagenicity Evaluation of Locally Produced Biphasic Calcium Phosphate Using Ames Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nur%20Fathin%20Alia%20Che%20Wahab">Nur Fathin Alia Che Wahab</a>, <a href="https://publications.waset.org/abstracts/search?q=Thirumulu%20Ponnuraj%20Kannan"> Thirumulu Ponnuraj Kannan</a>, <a href="https://publications.waset.org/abstracts/search?q=Zuliani%20Mahmood"> Zuliani Mahmood</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Ab.%20Rahman"> Ismail Ab.

The study was carried out to investigate the mutagenic effect of locally produced BCP using Ames test. Mutagenicity was evaluated with and without the addition of metabolic activation system (S9). This study was performed on Salmonella typhimurium TA98, TA102, TA1537, and TA1538 strains using preincubation assay method. The doses tested were 5000, 2500, 1250, 625, 313 µg/plate. Negative and positive controls were also included. The bacteria were incubated for 48 hours at 37 ± 0.5 °C. Then, the revertant colonies were counted. Data obtained were evaluated using non-statistical method. The mean number of revertant colonies in strains with and without S9 mix treated with locally produced BCP was less than double when compared to negative control for all the tested concentrations. The results from this study indicate that the locally produced BCP is non-mutagenic under the present test conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ames%20test" title="ames test">ames test</a>, <a href="https://publications.waset.org/abstracts/search?q=biphasic%20calcium%20phosphate" title=" biphasic calcium phosphate"> biphasic calcium phosphate</a>, <a href="https://publications.waset.org/abstracts/search?q=dentin%20regeneration" title=" dentin regeneration"> dentin regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=mutagenicity" title=" mutagenicity"> mutagenicity</a> </p> <a href="https://publications.waset.org/abstracts/51753/mutagenicity-evaluation-of-locally-produced-biphasic-calcium-phosphate-using-ames-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51753.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">323</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">880</span> A Situational Awareness Map for Allocating Relief Resources after Earthquake Occurrence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Reza%20Ranjbar">Hamid Reza Ranjbar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Reza%20Azmoude%20Ardalan"> Ali Reza Azmoude Ardalan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20%20Dehghani"> Hamid Dehghani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Sarajian"> Mohammad Reza Sarajian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Natural disasters are unexpected events which predicting them is difficult. Earthquake is one of the most devastating disasters among natural hazards with high rate of mortality and wide extent of damages. After the earthquake occurrence, managing the critical condition and allocating limited relief sources requiring a complete awareness of damaged area. The information for allocating relief teams should be precise and reliable as much as possible, and be presented in the appropriate time after the earthquake occurrence. This type of information was previously presented in the form of a damage map; conducting relief teams by using damage map mostly lead to waste of time for finding alive occupants under the rubble. In this research, a proposed standard for prioritizing damaged buildings in terms of requiring rescue and relief was presented. This standard prioritizes damaged buildings into four levels of priority including very high, high, moderate and low by considering key parameters such as type of land use, activity time, and inactivity time of each land use, time of earthquake occurrence and distinct index. The priority map by using the proposed standard could be a basis for guiding relief teams towards the areas with high relief priority. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Damage%20map" title="Damage map">Damage map</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=priority%20map" title=" priority map"> priority map</a>, <a href="https://publications.waset.org/abstracts/search?q=USAR" title=" USAR"> USAR</a> </p> <a href="https://publications.waset.org/abstracts/61827/a-situational-awareness-map-for-allocating-relief-resources-after-earthquake-occurrence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61827.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">879</span> A Study of the Views of Information Technologies Teachers regarding In-Service Training</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Halit%20Arslan">Halit Arslan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Sahin"> Ismail Sahin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Oguz%20Akturk"> Ahmet Oguz Akturk</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Celik"> Ismail Celik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today, the means of following the developments in the area of science and technology is to keep up with the pace of the advancements in this area. As is in every profession, apart from their personal efforts, the training of teachers in the period after they start their careers is only possible through in-service training. The aim of the present study is to determine the views of Information Technologies (IT) teachers regarding the in-service training courses organized by the Ministry of National Education. In this study, in which quantitative research methods and techniques were employed, the views of 196 IT teachers were collected by using the “Views on In-service Training” questionnaire developed by the authors of the paper. Independent groups t-test was used to determine whether the views of IT teachers regarding in-service training differed depending on gender, age and professional seniority. One-way analysis of variance (ANOVA) was used to investigate whether the views of IT teachers regarding in-service training differed depending on the number of in-service training courses they joined and the type of in-service training course they wanted to take. According to the findings obtained in the study, the views of IT teachers on in-service training did not show a significant difference depending on gender and age, whereas those views differed depending on professional seniority, the number of in-service training courses they joined and the type of in-service training course they wanted to take. <p
