The nature of the work undertaken by USAR means that staying out of a damaged or collapsed building structure is not usually an option for search and rescue personnel. As a result, there is always a risk that they could become victims. For this paper, a systematic and investigative review using desk research was undertaken to explore the role which structural engineering can play in assisting search and rescue personnel to conduct structural assessments when in the field. The focus is on how search and rescue personnel can assess damaged and collapsed building structures, not just in terms of the structural damage that may be countered, but also in relation to structural stability. Natural disasters, accidental emergencies, acts of terrorism and other extreme events can vary significantly in nature and ferocity, and can cause a wide variety of damage to building structures. It is not possible or, even realistic, to provide search and rescue personnel with definitive guidelines and procedures to assess damaged and collapsed building structures as there are too many variables to consider. However, understanding what implications damage may have upon the structural stability of a building structure will enable search and rescue personnel to judge better and quantify the risk from a life-safety standpoint. It is intended that this will allow search and rescue personnel to make informed decisions and ensure every effort is made to mitigate risk so that they do not become victims. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damaged%20and%20collapsed%20building%20structures" title="damaged and collapsed building structures">damaged and collapsed building structures</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20safety" title=" life safety"> life safety</a>, <a href="https://publications.waset.org/abstracts/search?q=quantifying%20risk" title=" quantifying risk"> quantifying risk</a>, <a href="https://publications.waset.org/abstracts/search?q=search%20and%20rescue%20personnel" title=" search and rescue personnel"> search and rescue personnel</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20assessments%20in%20the%20field" title=" structural assessments in the field"> structural assessments in the field</a> </p> <a href="https://publications.waset.org/abstracts/21334/urban-search-rescue-and-rapid-field-assessment-of-damaged-and-collapsed-building-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21334.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">393</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">12721</span> (Re)Assessing Clinical Spaces: How Do We Critically Provide Mental Health and Disability Support and Effective Care for Young People Who Are Impacted by Structural Violence and Structural Racism?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sireen%20Irsheid">Sireen Irsheid</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephanie%20Keeney%20Parks"> Stephanie Keeney Parks</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20A.%20Lindsey"> Michael A.

It is a sub-section of the main hospitals and the health sector, tasked with delivering responsive, immediate, and efficient medical services during a crisis. With the aim to prevent further crisis, the assessment of the cyber assets follows different methods, to distinguish its strengths and weaknesses, and in turn achieve cyber resiliency. The work focuses on assessments of cyber resilience in field hospitals with trends growing in both the field hospital and the health sector in general. This creates opportunities for the adverse attackers and the response improvement objectives for attaining cyber resilience, as the assessments allow users and stakeholders to know the level of risks with regards to its cyber assets. Thus, the purpose is to show the possible threat vectors which open up opportunities, with contrast to current trends in the assessment of the mobile field hospitals’ cyber assets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assessment%20framework" title="assessment framework">assessment framework</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber%20resilience" title=" cyber resilience"> cyber resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber%20security" title=" cyber security"> cyber security</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20field%20hospital" title=" mobile field hospital"> mobile field hospital</a> </p> <a href="https://publications.waset.org/abstracts/130214/improving-cyber-resilience-in-mobile-field-hospitals-towards-an-assessment-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130214.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">158</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">12719</span> Factors Related to Teachers’ Analysis of Classroom Assessments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hussain%20A.%20Alkharusi">Hussain A.

It aims improving teacher’s instruction and assessment as well as student learning. The present study investigated factors that might explain variation in teachers’ practices regarding analysis of classroom assessments. The factors considered in the investigation included gender, in-service assessment training, teaching load, teaching experience, knowledge in assessment, attitude towards quantitative aspects of assessment, and self-perceived competence in analysing assessments. Participants were 246 in-service teachers in Oman. Results of a stepwise multiple linear regression analysis revealed that self-perceived competence was the only significant factor explaining the variance in teachers’ analysis of assessments.

The benefits of improving the interface in the structural battery were tested by creating carbon fiber composite batteries (and independent graphite electrodes and lithium iron phosphate electrodes) with and without an improved interface. Mechanical data on the structural batteries were collected using tensile tests and electrochemical data was collected using scanning electron microscopy equipment. The full-cell lithium-ion structural batteries had capacity retention of over 80% exceeding 100 cycles with an average energy density of 52 W h kg−1 and a maximum energy density of 58 W h kg−1. Most scientific developments in the field of structural energy have been done with supercapacitors. Most scientific developments with structural batteries have been done where batteries are simply incorporated into the structural element. That method has limited advantages and can create mechanical disadvantages. This study aims to show that a large improvement in structure energy research can be made by improving the interface between the structural device and the battery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20materials" title="composite materials">composite materials</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20performance" title=" electrochemical performance"> electrochemical performance</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20interface" title=" polymer interface"> polymer interface</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20batteries" title=" structural batteries"> structural batteries</a> </p> <a href="https://publications.waset.org/abstracts/153279/improving-carbon-fiber-structural-battery-performance-with-polymer-interface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153279.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">109</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">12717</span> Vibration Propagation in Structures Through Structural Intensity Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Takhchi%20Jamal">Takhchi Jamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ouisse%20Morvan"> Ouisse Morvan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadoulet-Reboul%20Emeline"> Sadoulet-Reboul Emeline</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouhaddi%20Noureddine"> Bouhaddi Noureddine</a>, <a href="https://publications.waset.org/abstracts/search?q=Gagliardini%20Laurent"> Gagliardini Laurent</a>, <a href="https://publications.waset.org/abstracts/search?q=Bornet%20Frederic"> Bornet Frederic</a>, <a href="https://publications.waset.org/abstracts/search?q=Lakrad%20Faouzi"> Lakrad Faouzi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Structural intensity is a technique that can be used to indicate both the magnitude and direction of power flow through a structure from the excitation source to the dissipation sink. However, current analysis is limited to the low frequency range. At medium and high frequencies, a rotational component appear in the field, masking the energy flow and make its understanding difficult or impossible. The objective of this work is to implement a methodology to filter out the rotational components of the structural intensity field in order to fully understand the energy flow in complex structures. The approach is based on the Helmholtz decomposition. It allows to decompose the structural intensity field into rotational, irrotational, and harmonic components. Only the irrotational component is needed to describe the net power flow from a source to a dissipative zone in the structure. The methodology has been applied on academic structures, and it allows a good analysis of the energy transfer paths. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=structural%20intensity" title="structural intensity">structural intensity</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20flow" title=" power flow"> power flow</a>, <a href="https://publications.waset.org/abstracts/search?q=helmholt%20decomposition" title=" helmholt decomposition"> helmholt decomposition</a>, <a href="https://publications.waset.org/abstracts/search?q=irrotational%20intensity" title=" irrotational intensity"> irrotational intensity</a> </p> <a href="https://publications.waset.org/abstracts/143536/vibration-propagation-in-structures-through-structural-intensity-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143536.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">178</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">12716</span> Identifying the Structural Components of Old Buildings from Floor Plans</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shi-Yu%20Xu">Shi-Yu Xu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The top three risk factors that have contributed to building collapses during past earthquake events in Taiwan are: "irregular floor plans or elevations," "insufficient columns in single-bay buildings," and the "weak-story problem." Fortunately, these unsound structural characteristics can be directly identified from the floor plans. However, due to the vast number of old buildings, conducting manual inspections to identify these compromised structural features in all existing structures would be time-consuming and prone to human errors. This study aims to develop an algorithm that utilizes artificial intelligence techniques to automatically pinpoint the structural components within a building's floor plans. The obtained spatial information will be utilized to construct a digital structural model of the building. This information, particularly regarding the distribution of columns in the floor plan, can then be used to conduct preliminary seismic assessments of the building. The study employs various image processing and pattern recognition techniques to enhance detection efficiency and accuracy. The study enables a large-scale evaluation of structural vulnerability for numerous old buildings, providing ample time to arrange for structural retrofitting in those buildings that are at risk of significant damage or collapse during earthquakes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=structural%20vulnerability%20detection" title="structural vulnerability detection">structural vulnerability detection</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20recognition" title=" object recognition"> object recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20capacity%20assessment" title=" seismic capacity assessment"> seismic capacity assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=old%20buildings" title=" old buildings"> old buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a> </p> <a href="https://publications.waset.org/abstracts/169289/identifying-the-structural-components-of-old-buildings-from-floor-plans" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169289.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12715</span> Studying the Temperature Field of Hypersonic Vehicle Structure with Aero-Thermo-Elasticity Deformation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Geng%20Xiangren">Geng Xiangren</a>, <a href="https://publications.waset.org/abstracts/search?q=Liu%20Lei"> Liu Lei</a>, <a href="https://publications.waset.org/abstracts/search?q=Gui%20Ye-Wei"> Gui Ye-Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Tang%20Wei"> Tang Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang%20An-ling"> Wang An-ling</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The malfunction of thermal protection system (TPS) caused by aerodynamic heating is a latent trouble to aircraft structure safety. Accurately predicting the structure temperature field is quite important for the TPS design of hypersonic vehicle. Since Thornton’s work in 1988, the coupled method of aerodynamic heating and heat transfer has developed rapidly. However, little attention has been paid to the influence of structural deformation on aerodynamic heating and structural temperature field. In the flight, especially the long-endurance flight, the structural deformation, caused by the aerodynamic heating and temperature rise, has a direct impact on the aerodynamic heating and structural temperature field. Thus, the coupled interaction cannot be neglected. In this paper, based on the method of static aero-thermo-elasticity, considering the influence of aero-thermo-elasticity deformation, the aerodynamic heating and heat transfer coupled results of hypersonic vehicle wing model were calculated. The results show that, for the low-curvature region, such as fuselage or center-section wing, structure deformation has little effect on temperature field. However, for the stagnation region with high curvature, the coupled effect is not negligible. Thus, it is quite important for the structure temperature prediction to take into account the effect of elastic deformation. This work has laid a solid foundation for improving the prediction accuracy of the temperature distribution of aircraft structures and the evaluation capacity of structural performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerothermoelasticity" title="aerothermoelasticity">aerothermoelasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20deformation" title=" elastic deformation"> elastic deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20temperature" title=" structural temperature"> structural temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-field%20coupling" title=" multi-field coupling"> multi-field coupling</a> </p> <a href="https://publications.waset.org/abstracts/22907/studying-the-temperature-field-of-hypersonic-vehicle-structure-with-aero-thermo-elasticity-deformation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22907.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">341</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">12714</span> Vibration Propagation in Body-in-White Structures Through Structural Intensity Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jamal%20Takhchi">Jamal Takhchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The understanding of vibration propagation in complex structures such as automotive body in white remains a challenging issue in car design regarding NVH performances. The current analysis is limited to the low frequency range where modal concepts are dominant. Higher frequencies, between 200 and 1000 Hz, will become critical With the rise of electrification. EVs annoying sounds are mostly whines created by either Gears or e-motors between 300 Hz and 2 kHz. Structural intensity analysis was Experienced a few years ago on finite element models. The application was promising but limited by the fact that the propagating 3D intensity vector field is masked by a rotational Intensity field. This rotational field should be filtered using a differential operator. The expression of this operator in the framework of finite element modeling is not yet known. The aim of the proposed work is to implement this operator in the current dynamic solver (NASTRAN) of Stellantis and develop the Expected methodology for the mid-frequency structural analysis of electrified vehicles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=structural%20intensity" title="structural intensity">structural intensity</a>, <a href="https://publications.waset.org/abstracts/search?q=NVH" title=" NVH"> NVH</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20in%20white" title=" body in white"> body in white</a>, <a href="https://publications.waset.org/abstracts/search?q=irrotatational%20intensity" title=" irrotatational intensity"> irrotatational intensity</a> </p> <a href="https://publications.waset.org/abstracts/142155/vibration-propagation-in-body-in-white-structures-through-structural-intensity-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142155.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">155</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">12713</span> An Exploratory Study of Reliability of Ranking vs. Rating in Peer Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yang%20Song">Yang Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Yifan%20Guo"> Yifan Guo</a>, <a href="https://publications.waset.org/abstracts/search?q=Edward%20F.%20Gehringer"> Edward F.

With peer assessment, not only do students receive more copious assessments; they also learn to become assessors. In recent decades, more educational peer assessments have been facilitated by online systems. Those online systems are designed differently to suit different class settings and student groups, but they basically fall into two categories: rating-based and ranking-based. The rating-based systems ask assessors to rate the artifacts one by one following some review rubrics. The ranking-based systems allow assessors to review a set of artifacts and give a rank for each of them. Though there are different systems and a large number of users of each category, there is no comprehensive comparison on which design leads to higher reliability. In this paper, we designed algorithms to evaluate assessors' reliabilities based on their rating/ranking against the global ranks of the artifacts they have reviewed. These algorithms are suitable for data from both rating-based and ranking-based peer assessment systems. The experiments were done based on more than 15,000 peer assessments from multiple peer assessment systems. We found that the assessors in ranking-based peer assessments are at least 10% more reliable than the assessors in rating-based peer assessments. Further analysis also demonstrated that the assessors in ranking-based assessments tend to assess the more differentiable artifacts correctly, but there is no such pattern for rating-based assessors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=peer%20assessment" title="peer assessment">peer assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=peer%20rating" title=" peer rating"> peer rating</a>, <a href="https://publications.waset.org/abstracts/search?q=peer%20ranking" title=" peer ranking"> peer ranking</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability" title=" reliability"> reliability</a> </p> <a href="https://publications.waset.org/abstracts/66206/an-exploratory-study-of-reliability-of-ranking-vs-rating-in-peer-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66206.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">439</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">12712</span> The Effect of a Theoretical and Practical Training Program on Student Teachers’ Acquisition of Objectivity in Self-Assessments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zilungile%20Sosibo">Zilungile Sosibo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Constructivism in teacher education is growing tremendously in both the developed and developing world. Proponents of constructivism emphasize active engagement of students in the teaching and learning process. In an effort to keep students engaged while they learn to learn, teachers use a variety of methods to incorporate constructivism in the teaching-learning situations. One area that has a potential for realizing constructivism in the classroom is self-assessment. Sadly, students are rarely involved in the assessment of their work. Instead, the most knowing teacher dominates this process. Student involvement in self-assessments has a potential to teach student teachers to become objective assessors of their students’ work by the time they become credentialed. This is important, as objectivity in assessments is a much-needed skill in the classroom contexts within which teachers deal with students from diverse backgrounds and in which biased assessments should be avoided at all cost. The purpose of the study presented in this paper was to investigate whether student teachers acquired the skills of administering self-assessments objectively after they had been immersed in a formal training program and participated in four sets of self-assessments. The objectives were to determine the extent to which they had mastered the skills of objective self-assessments, their growth and development in this area, and the challenges they encountered in administering self-assessments objectively. The research question was: To what extent did student teachers acquire objectivity in self-assessments after their theoretical and practical engagement in this activity? Data were collected from student teachers through participant observation and semi-structured interviews. The design was a qualitative case study. The sample consisted of 39 final-year student teachers enrolled in a Bachelor of Education teacher education program at a university in South Africa. Results revealed that the formal training program and participation in self-assessments had a minimal effect on students’ acquisition of objectivity in self-assessments, due to the factors associated with self-aggrandizement and hegemony, the latter resulting from gender, religious and racial differences. These results have serious implications for the need to incorporate self-assessments in the teacher-education curriculum, as well as for extended formal training programs for student teachers on assessment in general. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=objectivity" title="objectivity">objectivity</a>, <a href="https://publications.waset.org/abstracts/search?q=self-assessment" title=" self-assessment"> self-assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20teachers" title=" student teachers"> student teachers</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20education%20curriculum" title=" teacher education curriculum"> teacher education curriculum</a> </p> <a href="https://publications.waset.org/abstracts/60516/the-effect-of-a-theoretical-and-practical-training-program-on-student-teachers-acquisition-of-objectivity-in-self-assessments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60516.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">273</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">12711</span> Mechanical Properties of Ancient Timber Structure Based on the Non Destructive Test Method: A Study to Feiyun Building, Shanxi, China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Annisa%20Dewanti%20Putri">Annisa Dewanti Putri</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang%20Juan"> Wang Juan</a>, <a href="https://publications.waset.org/abstracts/search?q=Y.%20Qing%20Shan"> Y.

This was conducted within every class by incorporating one level of the eight levels of intelligence into small group work in stations. Every class was conducted utilizing small-group instruction. Achievement levels were measured through various forms of collected data that expressed student understandings in class through formative assessments versus student understandings on summative assessments. The data samples included: assessments (i.e. summative and formative assessments), observable data, video recordings, a daily log book, student surveys, and checklists kept during the observation periods. Formative assessments were analyzed during each class period to measure in-class understanding. Summative assessments were dissected per question per accuracy to review the effects of each intelligence implemented. The data was collated into a coding workbook for further analysis to conclude the resulting themes of the research. These themes include 1) there was no correlation to multiple levels of intelligence enhancing student achievement, 2) bodily-kinesthetic intelligence showed to be the intelligence that had the most improvement on test questions and 3) out of all of the bits of intelligence, interpersonal intelligence enhanced student understanding in class. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stations" title="stations">stations</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20group%20instruction" title=" small group instruction"> small group instruction</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20levels%20of%20intelligence" title=" multiple levels of intelligence"> multiple levels of intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathematics" title=" Mathematics"> Mathematics</a>, <a href="https://publications.waset.org/abstracts/search?q=Algebra%201" title=" Algebra 1"> Algebra 1</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20achievement" title=" student achievement"> student achievement</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20school" title=" secondary school"> secondary school</a>, <a href="https://publications.waset.org/abstracts/search?q=instructional%20Pedagogies" title=" instructional Pedagogies"> instructional Pedagogies</a> </p> <a href="https://publications.waset.org/abstracts/166609/the-effects-of-multiple-levels-of-intelligence-in-an-algebra-1-classroom" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166609.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">111</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">12708</span> Magneto-Electric Behavior a Couple Aluminum / Steel Xc48</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Mekroud">A.

Albert, Uganda, on the rift flank where the gross sedimentary fill is typically less than 2,000m. The field was discovered in 2006 and encountered about 20.4m of net pay across three (3) stratigraphic intervals within the discovery well. The field covers an area of 3 km2, with the structural configuration comprising a 3-way dip-closed hanging wall anticline that seals against the basement to the southeast along the bounding fault. Field X had been mapped on reprocessed 3D seismic data, which was originally acquired in 2007 and reprocessed in 2013. The seismic data quality is good across the field, and reprocessing work reduced the uncertainty in the location of the bounding fault and enhanced the lateral continuity of reservoir reflectors. The current study was a re-evaluation of Field X to refine fault interpretation and understand the structural uncertainties associated with the field. The seismic data, and three (3) wells datasets were used during the study. The evaluation followed standard workflows using Petrel software and structural attribute analysis. The process spanned from seismic- -well tie, structural interpretation, and structural uncertainty analysis. Analysis of three (3) well ties generated for the 3 wells provided a geophysical interpretation that was consistent with geological picks. The generated time-depth curves showed a general increase in velocity with burial depth. However, separation in curve trends observed below 1100m was mainly attributed to minimal lateral variation in velocity between the wells. In addition to Attribute analysis, three velocity modeling approaches were evaluated, including the Time-Depth Curve, Vo+ kZ, and Average Velocity Method. The generated models were calibrated at well locations using well tops to obtain the best velocity model for Field X. The Time-depth method resulted in more reliable depth surfaces with good structural coherence between the TWT and depth maps with minimal error at well locations of 2 to 5m. Both the NNE-SSW rift border fault and minor faults in the existing interpretation were reevaluated. However, the new interpretation delineated an E-W trending fault in the northern part of the field that had not been interpreted before. The fault was interpreted at all stratigraphic levels and thus propagates from the basement to the surface and is an active fault today. It was also noted that the entire field is less faulted with more faults in the deeper part of the field. The major structural uncertainties defined included 1) The time horizons due to reduced data quality, especially in the deeper parts of the structure, an error equal to one-third of the reflection time thickness was assumed, 2) Check shot analysis showed varying velocities within the wells thus varying depth values for each well, and 3) Very few average velocity points due to limited wells produced a pessimistic average Velocity model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20seismic%20data%20interpretation" title="3D seismic data interpretation">3D seismic data interpretation</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20uncertainties" title=" structural uncertainties"> structural uncertainties</a>, <a href="https://publications.waset.org/abstracts/search?q=attribute%20analysis" title=" attribute analysis"> attribute analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity%20modelling%20approaches" title=" velocity modelling approaches"> velocity modelling approaches</a> </p> <a href="https://publications.waset.org/abstracts/184066/re-evaluation-of-field-x-located-in-northern-lake-albert-basin-to-refine-the-structural-interpretation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184066.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">59</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">12706</span> Seismic Interpretation and Petrophysical Evaluation of SM Field, Libya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdalla%20Abdelnabi">Abdalla Abdelnabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yousf%20Abushalah"> Yousf Abushalah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The G Formation is a major gas producing reservoir in the SM Field, eastern, Libya. It is called G limestone because it consists of shallow marine limestone. Well data and 3D-Seismic in conjunction with the results of a previous study were used to delineate the hydrocarbon reservoir of Middle Eocene G-Formation of SM Field area. The data include three-dimensional seismic data acquired in 2009. It covers approximately an area of 75 mi² and with more than 9 wells penetrating the reservoir. Seismic data are used to identify any stratigraphic and structural and features such as channels and faults and which may play a significant role in hydrocarbon traps. The well data are used to calculation petrophysical analysis of S field. The average porosity of the Middle Eocene G Formation is very good with porosity reaching 24% especially around well W 6. Average water saturation was calculated for each well from porosity and resistivity logs using Archie’s formula. The average water saturation for the whole well is 25%. Structural mapping of top and bottom of Middle Eocene G formation revealed the highest area in the SM field is at 4800 ft subsea around wells W4, W5, W6, and W7 and the deepest point is at 4950 ft subsea. Correlation between wells using well data and structural maps created from seismic data revealed that net thickness of G Formation range from 0 ft in the north part of the field to 235 ft in southwest and south part of the field. The gas water contact is found at 4860 ft using the resistivity log. The net isopach map using both the trapezoidal and pyramid rules are used to calculate the total bulk volume. The original gas in place and the recoverable gas were calculated volumetrically to be 890 Billion Standard Cubic Feet (BSCF) and 630 (BSCF) respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20seismic%20data" title="3D seismic data">3D seismic data</a>, <a href="https://publications.waset.org/abstracts/search?q=well%20logging" title=" well logging"> well logging</a>, <a href="https://publications.waset.org/abstracts/search?q=petrel" title=" petrel"> petrel</a>, <a href="https://publications.waset.org/abstracts/search?q=kingdom%20suite" title=" kingdom suite"> kingdom suite</a> </p> <a href="https://publications.waset.org/abstracts/80267/seismic-interpretation-and-petrophysical-evaluation-of-sm-field-libya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80267.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">150</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">12705</span> Application of Mathematical Models for Conducting Long-Term Metal Fume Exposure Assessments for Workers in a Shipbuilding Factory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shu-Yu%20Chung">Shu-Yu Chung</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying-Fang%20Wang"> Ying-Fang Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Shih-Min%20Wang"> Shih-Min Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To conduct long-term exposure assessments are important for workers exposed to chemicals with chronic effects.

Then, the predicted long-term concentrations were used to determine the prior distribution in Bayesian decision analysis (BDA). Finally, the resultant posterior distributions were used to assess the long-term exposure and serve as basis for initiating control strategies for shipbuilding workers. Results show that the NF/FF model was a suitable for predicting the exposures of metal contents containing in welding fume. The resultant posterior distributions could effectively assess the long-term exposures of shipbuilding welders. Welders' long-term Fe, Mn and Pb exposures were found with high possibilities to exceed the action level indicating preventive measures should be taken for reducing welders' exposures immediately. Though the resultant posterior distribution can only be regarded as the best solution based on the currently available predicting and monitoring data, the proposed integrated approach can be regarded as a possible solution for conducting long term exposure assessment in the field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bayesian%20decision%20analysis" title="Bayesian decision analysis">Bayesian decision analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure%20assessment" title=" exposure assessment"> exposure assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=near%20field%20and%20far%20field%20model" title=" near field and far field model"> near field and far field model</a>, <a href="https://publications.waset.org/abstracts/search?q=shipbuilding%20industry" title=" shipbuilding industry"> shipbuilding industry</a>, <a href="https://publications.waset.org/abstracts/search?q=welding%20fume" title=" welding fume"> welding fume</a> </p> <a href="https://publications.waset.org/abstracts/96268/application-of-mathematical-models-for-conducting-long-term-metal-fume-exposure-assessments-for-workers-in-a-shipbuilding-factory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96268.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12704</span> Fatigue Crack Behaviour in a Residual Stress Field at Fillet Welds in Ship Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anurag%20Niranjan">Anurag Niranjan</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Fitzpatrick"> Michael Fitzpatrick</a>, <a href="https://publications.waset.org/abstracts/search?q=Yin%20Jin%20Janin"> Yin Jin Janin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jazeel%20Chukkan"> Jazeel Chukkan</a>, <a href="https://publications.waset.org/abstracts/search?q=Niall%20Smyth"> Niall Smyth</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fillet welds are used in joining longitudinal stiffeners in ship structures. Welding residual stresses in fillet welds are generally distributed in a non-uniform manner, as shown in previous research the residual stress redistribution occurs under the cyclic loading that is experienced by such joints during service, and the combination of the initial residual stress, local constraints, and loading can alter the stress field in ways that are extremely difficult to predict. As the residual stress influences the crack propagation originating from the toe of the fillet welds, full understanding of the residual stress field and how it evolves is very important for structural integrity calculations. Knowledge of the residual stress redistribution in the presence of a flaw is therefore required for better fatigue life prediction. Moreover, defect assessment procedures such as BS7910 offer very limited guidance for flaw acceptance and the associated residual stress redistribution in the assessment of fillet welds. Therefore the objective of this work is to study a surface-breaking flaw at the weld toe region in a fillet weld under cyclic load, in conjunction with residual stress measurement at pre-defined crack depths. This work will provide details of residual stress redistribution under cyclic load in the presence of a crack. The outcome of this project will inform integrity assessment with respect to the treatment of residual stress in fillet welds. Knowledge of the residual stress evolution for this weld geometry will be greatly beneficial for flaw tolerance assessments (BS 7910, API 591). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fillet%20weld" title="fillet weld">fillet weld</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue" title=" fatigue"> fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=residual%20stress" title=" residual stress"> residual stress</a>, <a href="https://publications.waset.org/abstracts/search?q=structure%20integrity" title=" structure integrity"> structure integrity</a> </p> <a href="https://publications.waset.org/abstracts/156016/fatigue-crack-behaviour-in-a-residual-stress-field-at-fillet-welds-in-ship-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156016.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12703</span> Creative Thinking in Structural Design of Historic Constructions </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Avraham%20Mosseri">Avraham Mosseri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The architectural conservation process of the built heritage is a very complex process dealing with the integration of professional knowledge from many fields like history, sociology, economy, engineering, etc. One of the most important fields is the structural field, which has a great influence on the final architectural and aesthetic solution of the built heritage. In many cases, the ability to protect and save the heritage values of the historical buildings is an outcome of the structural creativity and conceptual design of the conservation engineers. This creativity is especially important when dealing with structural engineering of historic construction, where there are a lot of constraints and contradictions between different aspects like aesthetics, artistic values, culture, authenticity, structural performance, etc. But in spite of the importance of this creativity in conservation engineering, many research efforts are mainly devoted to the structural analysis of historic construction, which of course is very important and vital. But, in general, more attention can be paid to the creative process in the conceptual stage. In this situation there is a need, in parallel to analysis research, to devote more resources in order to improve the creative and conceptual theories in relation to conservation engineering. This paper focuses on the creativity aspects in the structural design process in the conservation of historic buildings as part of conservation theories. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conservation" title="conservation">conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=creativity" title=" creativity"> creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=historic%20constructions" title=" historic constructions"> historic constructions</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20design" title=" structural design"> structural design</a> </p> <a href="https://publications.waset.org/abstracts/77877/creative-thinking-in-structural-design-of-historic-constructions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77877.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">242</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">12702</span> Analytical Study of the Structural Response to Near-Field Earthquakes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isidro%20Perez">Isidro Perez</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Nazari"> Maryam Nazari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Numerous earthquakes, which have taken place across the world, led to catastrophic damage and collapse of structures (e.g., 1971 San Fernando; 1995 Kobe-Japan; and 2010 Chile earthquakes). Engineers are constantly studying methods to moderate the effect this phenomenon has on structures to further reduce damage, costs, and ultimately to provide life safety to occupants. However, there are regions where structures, cities, or water reservoirs are built near fault lines. When an earthquake occurs near the fault lines, they can be categorized as near-field earthquakes. In contrary, a far-field earthquake occurs when the region is further away from the seismic source. A near-field earthquake generally has a higher initial peak resulting in a larger seismic response, when compared to a far-field earthquake ground motion. These larger responses may result in serious consequences in terms of structural damage which can result in a high risk for the public’s safety. Unfortunately, the response of structures subjected to near-field records are not properly reflected in the current building design specifications. For example, in ASCE 7-10, the design response spectrum is mostly based on the far-field design-level earthquakes. This may result in the catastrophic damage of structures that are not properly designed for near-field earthquakes. This research investigates the knowledge that the effect of near-field earthquakes has on the response of structures. To fully examine this topic, a structure was designed following the current seismic building design specifications, e.g. ASCE 7-10 and ACI 318-14, being analytically modeled, utilizing the SAP2000 software. Next, utilizing the FEMA P695 report, several near-field and far-field earthquakes were selected, and the near-field earthquake records were scaled to represent the design-level ground motions. Upon doing this, the prototype structural model, created using SAP2000, was subjected to the scaled ground motions. A Linear Time History Analysis and Pushover analysis were conducted on SAP2000 for evaluation of the structural seismic responses. On average, the structure experienced an 8% and 1% increase in story drift and absolute acceleration, respectively, when subjected to the near-field earthquake ground motions. The pushover analysis was ran to find and aid in properly defining the hinge formation in the structure when conducting the nonlinear time history analysis. A near-field ground motion is characterized by a high-energy pulse, making it unique to other earthquake ground motions. Therefore, pulse extraction methods were used in this research to estimate the maximum response of structures subjected to near-field motions. The results will be utilized in the generation of a design spectrum for the estimation of design forces for buildings subjected to NF ground motions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=near-field" title="near-field">near-field</a>, <a href="https://publications.waset.org/abstracts/search?q=pulse" title=" pulse"> pulse</a>, <a href="https://publications.waset.org/abstracts/search?q=pushover" title=" pushover"> pushover</a>, <a href="https://publications.waset.org/abstracts/search?q=time-history" title=" time-history"> time-history</a> </p> <a href="https://publications.waset.org/abstracts/97406/analytical-study-of-the-structural-response-to-near-field-earthquakes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97406.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12701</span> Cultural Heritage Impact Assessments and the Negotiation of Identity in South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rosabelle%20Boswell">Rosabelle Boswell</a> </p> <p class="card-text"><strong>Abstract:</strong></p> South Africa, a country with experience of both colonial rule and apartheid is now more than 25 years past its first democratic elections.

The field is located in the offshore Niger Delta where water depth ranges from 450 to 800 m. The objectives of this study are to explore deeper prospects and to ascertain the kind of traps that are favorable for the accumulation of hydrocarbon in the field. Six horizons with major and minor faults were identified and mapped in the field. Time structure maps of these horizons were generated and using the available check-shot data the maps were converted to top structure maps which were used to calculate the hydrocarbon volume. The results show that regional structural highs that are trending in northeast-southwest (NE-SW) characterized a large portion of the field. These highs were observed across all horizons revealing a regional post-depositional deformation. Three prospects were identified and evaluated to understand the different opportunities in the field. These include stratigraphic pinch out and bi-directional downlap. The results of this study show that the field has potentials for new opportunities that could be explored for further studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrocarbon" title="hydrocarbon">hydrocarbon</a>, <a href="https://publications.waset.org/abstracts/search?q=play" title=" play"> play</a>, <a href="https://publications.waset.org/abstracts/search?q=prospect" title=" prospect"> prospect</a>, <a href="https://publications.waset.org/abstracts/search?q=stratigraphy" title=" stratigraphy"> stratigraphy</a> </p> <a href="https://publications.waset.org/abstracts/86819/evaluation-of-hydrocarbon-prospects-of-ade-field-niger-delta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86819.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">270</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">12699</span> The Rigor and Relevance of the Mathematics Component of the Teacher Education Programmes in Jamaica: An Evaluative Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Avalloy%20McCarthy-Curvin">Avalloy McCarthy-Curvin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For over fifty years there has been widespread dissatisfaction with the teaching of Mathematics in Jamaica. Studies, done in the Jamaican context highlight that teachers at the end of training do not have a deep understanding of the mathematics content they teach. Little research has been done in the Jamaican context that targets the advancement of contextual knowledge on the problem to ultimately provide a solution. The aim of the study is to identify what influences this outcome of teacher education in Jamaica so as to remedy the problem. This study formatively evaluated the curriculum documents, assessments and the delivery of the curriculum that are being used in teacher training institutions in Jamaica to determine their rigor -the extent to which written document, instruction, and the assessments focused on enabling pre-service teachers to develop deep understanding of mathematics and relevance- the extent to which the curriculum document, instruction, and the assessments are focus on developing the requisite knowledge for teaching mathematics. The findings show that neither the curriculum document, instruction nor assessments ensure rigor and enable pre-service teachers to develop the knowledge and skills they need to teach mathematics effectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=relevance" title="relevance">relevance</a>, <a href="https://publications.waset.org/abstracts/search?q=rigor" title=" rigor"> rigor</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20understanding" title=" deep understanding"> deep understanding</a>, <a href="https://publications.waset.org/abstracts/search?q=formative%20evaluation" title=" formative evaluation"> formative evaluation</a> </p> <a href="https://publications.waset.org/abstracts/73020/the-rigor-and-relevance-of-the-mathematics-component-of-the-teacher-education-programmes-in-jamaica-an-evaluative-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73020.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">237</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">12698</span> Impact of Data and Model Choices to Urban Flood Risk Assessments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abhishek%20Saha">Abhishek Saha</a>, <a href="https://publications.waset.org/abstracts/search?q=Serene%20Tay"> Serene Tay</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerard%20Pijcke"> Gerard Pijcke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The availability of high-resolution topography and rainfall information in urban areas has made it necessary to revise modeling approaches used for simulating flood risk assessments. Lidar derived elevation models that have 1m or lower resolutions are becoming widely accessible. The classical approaches of 1D-2D flow models where channel flow is simulated and coupled with a coarse resolution 2D overland flow models may not fully utilize the information provided by high-resolution data. In this context, a study was undertaken to compare three different modeling approaches to simulate flooding in an urban area. The first model used is the base model used is Sobek, which uses 1D model formulation together with hydrologic boundary conditions and couples with an overland flow model in 2D. The second model uses a full 2D model for the entire area with shallow water equations at the resolution of the digital elevation model (DEM). These models are compared against another shallow water equation solver in 2D, which uses a subgrid method for grid refinement. These models are simulated for different horizontal resolutions of DEM varying between 1m to 5m. The results show a significant difference in inundation extents and water levels for different DEMs. They are also sensitive to the different numerical models with the same physical parameters, such as friction. The study shows the importance of having reliable field observations of inundation extents and levels before a choice of model and data can be made for spatial flood risk assessments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flooding" title="flooding">flooding</a>, <a href="https://publications.waset.org/abstracts/search?q=DEM" title=" DEM"> DEM</a>, <a href="https://publications.waset.org/abstracts/search?q=shallow%20water%20equations" title=" shallow water equations"> shallow water equations</a>, <a href="https://publications.waset.org/abstracts/search?q=subgrid" title=" subgrid"> subgrid</a> </p> <a href="https://publications.waset.org/abstracts/115700/impact-of-data-and-model-choices-to-urban-flood-risk-assessments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115700.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12697</span> Linking Pre-Class Engagement with Academic Achievement: The Role of Quests in a Flipped Chemistry Course</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anthony%20J.%20Rojas">Anthony J.

This study investigates the use of ‘Quests’, brief formative assessments administered at the start of class, to evaluate student understanding of assigned pre-class materials in an undergraduate chemistry course. Students completed Quests via Microsoft Forms, based on content from instructional videos and worksheets, and these assessments were mandatory, with no opportunity for make-up. This paper examines the correlation between Quest performance and overall course success, finding that students who performed well on the Quests consistently achieved higher final grades in the course. The findings suggest that Quests are effective in both reinforcing student engagement with pre-class content and predicting their broader academic performance. The implications of these results for flipped classroom strategies and student learning outcomes will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemistry" title="chemistry">chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=flipped%20classroom" title=" flipped classroom"> flipped classroom</a>, <a href="https://publications.waset.org/abstracts/search?q=attendance" title=" attendance"> attendance</a>, <a href="https://publications.waset.org/abstracts/search?q=assessments" title=" assessments"> assessments</a> </p> <a href="https://publications.waset.org/abstracts/192527/linking-pre-class-engagement-with-academic-achievement-the-role-of-quests-in-a-flipped-chemistry-course" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192527.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">25</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">12696</span> Structural, Magnetic and Magnetocaloric Properties of Iron-Doped Nd₀.₆Sr₀.₄MnO₃ Perovskite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Al-Yahmadi">Ismail Al-Yahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbasher%20Gismelseed"> Abbasher Gismelseed</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Al-Mammari"> Fatma Al-Mammari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Al-Rawas"> Ahmed Al-Rawas</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Yousif"> Ali Yousif</a>, <a href="https://publications.waset.org/abstracts/search?q=Imaddin%20Al-Omari"> Imaddin Al-Omari</a>, <a href="https://publications.waset.org/abstracts/search?q=Hisham%20Widatallah"> Hisham Widatallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elzain"> Mohamed Elzain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The influence of Fe-doping on the structural, magnetic and magnetocaloric properties of Nd₀.₆Sr₀.₄FeₓMn₁₋ₓO₃ (0≤ x ≤0.5) were investigated. The samples were synthesized by auto-combustion Sol-Gel method. The phase purity, crystallinity, and the structural properties for all prepared samples were examined by X-ray diffraction. XRD refinement indicates that the samples are crystallized in the orthorhombic single-phase with Pnma space group. Temperature dependence of magnetization measurements under a magnetic applied field of 0.02 T reveals that the samples with (x=0.0, 0.1, 0.2 and 0.3) exhibit a paramagnetic (PM) to ferromagnetic (FM) transition with decreasing temperature. The Curie temperature decreased with increasing Fe content from 256 K for x =0.0 to 80 K for x =0.3 due to increasing of antiferromagnetic superexchange (SE) interaction coupling. Moreover, the magnetization as a function of applied magnetic field (M-H) curves was measured at 2 K, and 300 K. the results of such measurements confirm the temperature dependence of magnetization measurements. The magnetic entropy change|∆SM | was evaluated using Maxwell's relation. The maximum values of the magnetic entropy change |-∆SMax |for x=0.0, 0.1, 0.2, 0.3 are found to be 15.35, 5.13, 3.36, 1.08 J/kg.K for an applied magnetic field of 9 T.

In 1968 the British intelligence community saw one of its biggest transformations: the creation of an independent, central cadre of analysts. The ‘Assessments Staff’ was a novel attempt to improve the quality of analysis by fostering independence from departmental biases that had long plagued British intelligence. Seconded into the Cabinet Office, staff were allocated a ‘desk,’ and their role was to produce high level assessments for the most senior readers in the land. At the same time, efforts were made to ‘professionalise’ the analysts. This paper is based on a detailed archival examination of the JIC’s documentary files. It will recount the reasons behind this organisational reform, what the changes entailed, and whether they were a success. The changes were immediately brought to bear with the intelligence assessments prior to the Soviet invasion of Czechoslovakia, something that the JIC failed to appreciate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intelligence" title="intelligence">intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=cold%20war%20history" title=" cold war history"> cold war history</a>, <a href="https://publications.waset.org/abstracts/search?q=analysis" title=" analysis"> analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=united%20kingdom" title=" united kingdom"> united kingdom</a> </p> <a href="https://publications.waset.org/abstracts/165753/the-professionalisation-of-british-intelligence-analysts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165753.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">78</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">12694</span> Environmental Impact Assessments in Peru: Tools for Violence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Degregori">Nadia Degregori</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper focuses on Peru’s Environmental Impact Assessment’s communication and participation mechanisms, whose rationale is to prevent conflictive situations by –supposedly- providing high-quality information about mining projects and their impacts to affected stakeholders. It is argued that, in fact, these mechanisms enhance citizens’ feelings of fear and/or mistrust towards mining projects and the companies behind them because their design follows a top-down perspective that limits “participation” to a passive reception of information, and which does not address power unbalances between communities and companies or government. As well, the paper contends that this way of managing the social aspects of Environmental Impact Assessments in Peru leads stakeholders who possess less power (typically communities) to incline towards maintaining the status quo and avoiding negotiations with either the central government or mining companies as a defence mechanism for avoiding a bad negotiation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community%20relations" title="community relations">community relations</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20impact%20assessments" title=" environmental impact assessments"> environmental impact assessments</a>, <a href="https://publications.waset.org/abstracts/search?q=governance%20and%20participation" title=" governance and participation"> governance and participation</a>, <a href="https://publications.waset.org/abstracts/search?q=mining" title=" mining"> mining</a>, <a href="https://publications.waset.org/abstracts/search?q=Peru" title=" Peru"> Peru</a> </p> <a href="https://publications.waset.org/abstracts/15743/environmental-impact-assessments-in-peru-tools-for-violence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15743.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">434</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">12693</span> Study on Effective Continuous Assessments Methods to Improve Undergraduates English Language Skills</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20M.%20R.%20Siriwardhana">K.

Today, most of the university students in Sri Lanka are eagerly exploring knowledge giving special consideration to English as their 2nd Language with the understanding that to climb up the career ladder, English is inevitable both in local and international contexts. However, still a considerable failing rate in English can also be seen among the Sri Lankan undergraduates Further, most of the Sri Lankan universities now practice English as their medium of instructions making English a credited Subject to brighten the future of the Sri Lankan students. Accordingly, in many universities an array of assessments are employed to evaluate undergraduates’ competence in English language. The main objective of this study was to ascertain the effective assessment methods to improve the 2nd language skills of the Sri Lankan university students which also create a more interest in them to learn English. Accordingly, hundred (100) undergraduates were selected as the research sample and the primary data was collected employing a semi structured questionnaire along with class room observations and semi structured interviews. Data was mainly analyzed descriptively employing graphical illustrations. According to the research findings, it was revealed that practical assessments such as oral tests, competitive drama and presentations are more effective in improving their language skills and preferred by the majority of students than written assignments and papers. Further, most of the students have scored better in practical assignments than in the written assignments. Hence, the study concludes that best and the benefited way of improving English language skills of Sri Lankan undergraduates is practical assessments as it gives them the opportunity to apply the language with much confidence and competence in actual situations. Further, the study recommends the language teachers to improve their own skills and creativity in practicing and employing such assessments as it will develop both second language teaching and learning skills. Ultimately, the university graduates will be able to secure their positions internationally as they are well capable in English, the lingua franca of the world. <p
