Elliptic Curve Cryptography (ECC), which allows smaller key length as compared to conventional public key crypto systems, has thus become a very attractive choice for many applications. This paper describes implementation of an elliptic curve cryptography (ECC) encryption engine on a FPGA. The system has been implemented in 2 different key sizes, which are 131 bits and 163 bits. Area and timing analysis are provided for both key sizes for comparison. The crypto system, which has been implemented on Altera’s EPF10K200SBC600-1, has a hardware size of 5945/9984 and 6913/9984 of logic cells for 131 bits implementation and 163 bits implementation respectively. The crypto system operates up to 43 MHz, and performs point multiplication operation in 11.3 ms for 131 bits implementation and 14.9 ms for 163 bits implementation. In terms of speed, our crypto system is about 8 times faster than the software implementation of the same system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elliptic%20curve%20cryptography" title="elliptic curve cryptography">elliptic curve cryptography</a>, <a href="https://publications.waset.org/abstracts/search?q=FPGA" title=" FPGA"> FPGA</a>, <a href="https://publications.waset.org/abstracts/search?q=key%20sizes" title=" key sizes"> key sizes</a>, <a href="https://publications.waset.org/abstracts/search?q=memory" title=" memory "> memory </a> </p> <a href="https://publications.waset.org/abstracts/13762/implementation-of-elliptic-curve-cryptography-encryption-engine-on-a-fpga" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13762.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">319</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">286</span> Assessment of Radiological Dose for Th-232 Laboratory Accumulated in Tropical Freshwater Fish</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zal%20U%E2%80%99yun%20Wan%20Mahmood">Zal U’yun Wan Mahmood</a>, <a href="https://publications.waset.org/abstracts/search?q=Norfaizal%20Mohamed"> Norfaizal Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Nita%20Salina%20Abu%20Bakar"> Nita Salina Abu Bakar</a>, <a href="https://publications.waset.org/abstracts/search?q=Yii%20Mei%20Wo"> Yii Mei Wo</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Kadir%20Ishak"> Abdul Kadir Ishak</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Noh%20Sawon"> Mohamad Noh Sawon</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Tarmizi%20Ishak"> Mohd Tarmizi Ishak</a>, <a href="https://publications.waset.org/abstracts/search?q=Khairul%20Nizam%20Razali"> Khairul Nizam Razali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study of thorium radiotracer bioaccumulation in the whole body tropical freshwater fish (Anabas testudeneus; climb pearch) was performed. The objective of this study was to evaluate the effect of different Th-232 activity concentration andradiological dose in Anabas testudeneus under the laboratory bioaccumulation condition. Anabas testudeneus adults were exposed to different waterborne Th-232 levels: 0 BqL-1 (control), 50 BqL-1, 100 BqL-1,150 BqL-1and 200 BqL-1for 30 days. Radionuclide concentration ratios between the whole body levels and water levels were calculated and; total dose rates and risk quotients using ERICA Assessment Tool were also estimated. The results showed the increase of waterborne Th-232 concentration corresponded to a progressive decrease of Th concentration ratio. Meanwhile, the total dose rate (internal and external) in the whole body of Anabas testudeneus less than the ERICA dose rate screening value of 10 µGyh-1 and the risk quotient less than one. Thus, the findings can be concluded that the radiological dose of Th-232 to Anabas testudeneus is a very low probability and the situation may be considered to be of negligible radiological concern. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anabas%20testudeneus" title="Anabas testudeneus">Anabas testudeneus</a>, <a href="https://publications.waset.org/abstracts/search?q=bioaccumulation" title=" bioaccumulation"> bioaccumulation</a>, <a href="https://publications.waset.org/abstracts/search?q=radiological%20dose" title=" radiological dose"> radiological dose</a>, <a href="https://publications.waset.org/abstracts/search?q=Th-232" title=" Th-232"> Th-232</a> </p> <a href="https://publications.waset.org/abstracts/27965/assessment-of-radiological-dose-for-th-232-laboratory-accumulated-in-tropical-freshwater-fish" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27965.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">325</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">285</span> Islamic Credit Risk Management in Murabahah Financing: The Study of Islamic Banking in Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siti%20Nor%20Amira%20Bt.%20Mohamad">Siti Nor Amira Bt.

It was presently in any Islamic financial transactions in order to comply with shariah rules. However, the existence of risk in Murabahah contract of financing is an ability that the counterparty is unable to complete its obligations within the agreed terms. Therefore, it is called as credit or default risk. Credit risk occurs when the client fails to make timely payment after the bank makes complete delivery of assets. Thus, it affects the growth of the bank as the banking business is in no position to have appropriate measures to cover the risk. Therefore, the bank may impose penalty on the outstanding balance. This paper aims to highlight the credit risk determinant and issues surrounding in Islamic bank in Malaysia in terms of Murabahah financing and how to manage it by using the proper techniques. Finally, it explores the credit risk management concept that might solve the problems arise. The study found that the credit risk can be managed properly by improving the use of comprehensive reference checklist of business partners on their character and past performance as well as their comprehensive database. Besides that, prevention of credit risk can be done by using collateral as security against the risk and we also argue on the Shariah guidelines and procedures should be implement coherently by the banking business because so that the risk would be control by having an effective instrument for Islamic modes of financing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Islamic%20banking" title="Islamic banking">Islamic banking</a>, <a href="https://publications.waset.org/abstracts/search?q=credit%20risk" title=" credit risk"> credit risk</a>, <a href="https://publications.waset.org/abstracts/search?q=Murabahah%20financing" title=" Murabahah financing"> Murabahah financing</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20mitigation" title=" risk mitigation"> risk mitigation</a> </p> <a href="https://publications.waset.org/abstracts/6911/islamic-credit-risk-management-in-murabahah-financing-the-study-of-islamic-banking-in-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6911.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">456</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">284</span> Contemporary Visual Art and Shariah: A Conceptual Framework</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ishak%20Ramli">Ishak Ramli</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Noorman%20Masrek"> Mohamad Noorman Masrek</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhamad%20Abdul%20Aziz%20Ab%20Gani"> Muhamad Abdul Aziz Ab Gani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Islam places restrictions and limitation to the creation and ownership of visual art.

Therefore, the purpose of this research is to identify the challenges of implementing the inculcation of noble values in teaching in primary schools. This study was conducted at four North Zone Peninsular Malaysia schools. This study was used a qualitative approach in the form of case studies. The qualitative approach aims at gaining meaning and a deep understanding of the phenomenon studied from the perspectives of the study participants and not intended to make the generalization. The sample in this study consists of eight teachers who teach in four types of schools that have been chosen purposively. The method of data collection is through semi-structured interviews used in this study. The comparative method is continuously used in this study to analyze the primary data collected. The study found that the main challenges faced by teachers were students' problems and class control so that teachers felt difficult to the inculcation of noble values in teaching. In addition, the language challenge is difficult for students to understand. Similarly, peers are also challenging because students are more easily influenced by friends rather than listening to teachers' instructions. The last challenge was the influence of technology and mass media electronic more widespread. The findings suggest that teachers need to innovate in order to assist the school in inculcating religious and moral education towards the students. The school through guidance and counseling teachers can also plan some activities that are appropriate to the student's present condition. Through this study, teachers and the school should work together to develop the values of students in line with the needs of the National Education Philosophy that wishes to produce intelligent, emotional, spiritual, intellectual and social human capital. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=challenges" title="challenges">challenges</a>, <a href="https://publications.waset.org/abstracts/search?q=implementation" title=" implementation"> implementation</a>, <a href="https://publications.waset.org/abstracts/search?q=inculcation" title=" inculcation"> inculcation</a>, <a href="https://publications.waset.org/abstracts/search?q=noble%20values" title=" noble values"> noble values</a> </p> <a href="https://publications.waset.org/abstracts/94564/challenges-in-implementing-the-inculcation-of-noble-values-during-teaching-by-primary-schools-teachers-in-peninsular-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94564.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">184</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">282</span> Utilizing Bario Rice, a Natural Red-Pigmented Rice from Sarawak, Malaysia, in the Development of Gluten-Free Bread</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Macdalyna%20Esther%20Ronie">Macdalyna Esther Ronie</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasmadi%20Mamat"> Hasmadi Mamat</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Hazim%20Abdul%20Aziz"> Ahmad Hazim Abdul Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Khairi%20Zainol"> Mohamad Khairi Zainol</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Current trends in gluten-free food development are increasingly leaning towards the utilization of pigmented rice flour, with a particular focus on Bario Merah Sederhana (BMS), a red-pigmented rice native to Sarawak, Malaysia. This study delves into the evaluation of the nutritional, textural, and sensory attributes of gluten-free rice bread produced from a blend of BMS rice flour and potato starch. The resulting samples are denoted as F1 (100% BMS rice flour), F2 (90% BMS rice flour and 10% potato starch), F3 (80% BMS rice flour and 20% potato starch), and F4 (70% BMS rice flour and 30% potato starch). Comparatively, these gluten-free rice bread formulations exhibit higher levels of ash and crude fiber, along with lower carbohydrate content when juxtaposed with conventional wheat bread. Notably, the crude protein content of the rice bread diminishes significantly (p<0.05) as the proportion of rice flour decreases, primarily due to the higher protein content found in wheat flour. The crumb of the rice bread appears darker owing to the red pigment in the rice flour, while the crust is lighter than that of the control sample, possibly attributable to a reduced Maillard reaction. Among the various rice bread formulations, F4 stands out with the least dough and bread hardness, accompanied by the highest levels of stickiness and springiness in both dough and bread, respectively. In sensory evaluations, wheat bread garners the highest rating (p<0.05). However, within the realm of rice breads, F4 emerges as a viable and acceptable formulation, as indicated by its commendable scores in color (7.03), flavor (5.73), texture (6.03), and overall acceptability (6.18). These findings underscore the potential of BMS in the creation of gluten-free rice breads, with the formulation consisting of 70% rice flour and 30% potato starch emerging as a well-received and suitable option. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gluten-free%20bread" title="gluten-free bread">gluten-free bread</a>, <a href="https://publications.waset.org/abstracts/search?q=bario%20rice" title=" bario rice"> bario rice</a>, <a href="https://publications.waset.org/abstracts/search?q=proximate%20composition" title=" proximate composition"> proximate composition</a>, <a href="https://publications.waset.org/abstracts/search?q=sensory%20evaluation" title=" sensory evaluation"> sensory evaluation</a> </p> <a href="https://publications.waset.org/abstracts/172723/utilizing-bario-rice-a-natural-red-pigmented-rice-from-sarawak-malaysia-in-the-development-of-gluten-free-bread" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172723.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">281</span> Measuring Multi-Class Linear Classifier for Image Classification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Susilawati%20Mohamad">Fatma Susilawati Mohamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Azizah%20Abdul%20Manaf"> Azizah Abdul Manaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Fadhillah%20Ahmad"> Fadhillah Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Zarina%20Mohamad"> Zarina Mohamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Wan%20Suryani%20Wan%20Awang"> Wan Suryani Wan Awang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A simple and robust multi-class linear classifier is proposed and implemented.

The reactor model and S-function are developed using m.file. After developing the S-function of CSTR model, User-Defined functions are used to link to SIMULINK file. Results that are obtained from simulation and temperature control were better when using Fuzzy logic control compared to PID control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CSTR" title="CSTR">CSTR</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=PID" title=" PID"> PID</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic" title=" fuzzy logic"> fuzzy logic</a> </p> <a href="https://publications.waset.org/abstracts/56171/modelling-for-temperature-non-isothermal-continuous-stirred-tank-reactor-using-fuzzy-logic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56171.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">457</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">279</span> Evaluating the Administrative Buildings from the Perspective of Democratic Architecture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tajuddin%20Mohamad%20Rasdi">Tajuddin Mohamad Rasdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Chung%20Ming%20Zhe"> Chung Ming Zhe</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurul%20Anida%20Mohamad"> Nurul Anida Mohamad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research paper aims to examine the lack of the idea of democracy and its concept among Malaysia’s citizens. In fact, all civil servants, whether federal or state departments, are the machinery of citizens. The objective of this research is to evaluate the administrative buildings in Selangor from the perspective of democratic architecture. The methodology used in this research is by reviewing and evaluating the selected administrative building, Majlis Bandaraya Petaling Jaya, as a case study, and the interview was conducted. The data collection was recorded based on a few criteria of the following architectural characteristic and management principles (public square, town hall, meeting rooms, convenient parking space, humanitarian spaces, public spaces) and architectural design elements (scale and massing, ornament, elevational language, accessibility, and spatial hierarchy). The analysis result shows that the administrative building elements which show the idea of democracy are not reflected well in some of the criteria that restrict the public, but those setbacks could be improved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=democratic%20architecture" title="democratic architecture">democratic architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=case%20study" title=" case study"> case study</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20elements" title=" design elements"> design elements</a>, <a href="https://publications.waset.org/abstracts/search?q=administrative%20buildings" title=" administrative buildings"> administrative buildings</a> </p> <a href="https://publications.waset.org/abstracts/162106/evaluating-the-administrative-buildings-from-the-perspective-of-democratic-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162106.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">117</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">278</span> Sustainability Education among the Malaysian Media </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Saifudin%20Mohamad%20Saleh">Mohamad Saifudin Mohamad Saleh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper provides a discussion of the importance of sustainability education among the Malaysian media. Without doubt, media play a crucial role in promoting the sustainable or so called “eco-system” society for a better future. Since 2002, the role of media as one of the vital stakeholders particularly in educating the society in three main areas of sustainable education including on environment, economy and society has been clearly highlights on the World Summit for Sustainable Development (WSSD) that was held in Johannesburg. In this paper, six media practitioners from two local Malaysia newspapers organization were interviewed by the researcher in order to identify their understanding about sustainability education; their perception about the pivotal role in sustainability education and the challenges faced by them in the process of educating society about sustainability issues. The findings of this study showed that most of Malaysian media practitioners have displayed clear understanding about sustainability education and they also realize their huge responsibility for not only informing but also educating society in having a sustainable lifestyle. The ultimate challenge in sustainability education faced by the media is to make the public really understand the importance of sustainable lifestyle. Overall, from this study, it is hoped to provide more possible direction in sustainability education not only among the Malaysian media but also all media in the entire world, particularly the developing and Southeast Asian countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=media" title="media">media</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability%20education" title=" sustainability education"> sustainability education</a>, <a href="https://publications.waset.org/abstracts/search?q=Malaysia" title=" Malaysia"> Malaysia</a> </p> <a href="https://publications.waset.org/abstracts/24814/sustainability-education-among-the-malaysian-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24814.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">598</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">277</span> The Role of Human Beings as Caliphs in Preserving Nature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Firdaus%20Khairi%20Abdul%20Kadir">Firdaus Khairi Abdul Kadir</a>, <a href="https://publications.waset.org/abstracts/search?q=Nazihah%20Rusli"> Nazihah Rusli</a>, <a href="https://publications.waset.org/abstracts/search?q=Noor%20Aisyah%20Abdul%20Aziz"> Noor Aisyah Abdul Aziz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Islam is a comprehensive religion encompassing all aspects of society’s life such as social, economic, political, cultural and environmental. The environment is part of the manifestation of God’s greatness which has pearls of wisdom, bestowed upon human beings to make them realize that everything is in the hands of God (Allah SWT). However, the equilibrium of nature could be disturbed from the excessive exploitation by humans’ hands. As a caliph on this earth, it is the responsibility of human beings to look after the environment proactively. Besides, Islam calls for the execution of accountable development and respecting the principles of sustainability. Therefore, this study focuses on the role of human beings as caliphs on this earth who are responsible for nature and their acts in conserving and preserving the environment based on the approach of religious education.

WSN is constantly changing because of the rapid technological advancements in sensor elements such as radio, battery and operating systems. The Medium Access Control (MAC) protocols remain very vital in the WSN because of its role in coordinating communication amongst the sensors. Other than battery consumption, packet collision, network lifetime and latency are factors that largely depend on WSN MAC protocol and these factors have been widely treated in recent days. In this paper, we survey some latest proposed WSN Contention-based, Scheduling-based and Hybrid MAC protocols while presenting an examination, correlation of advantages and limitations of each protocol. Concentration is directed towards investigating the treatment of Quality of Service (QoS) performance metrics within these particular protocols. The result shows that majority of the protocols leaned towards energy conservation. We, therefore, believe that other performance metrics of guaranteed QoS such as latency, throughput, packet loss, network and bandwidth availability may play a critical role in the design of future MAC protocols for WSNs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=WSN" title="WSN">WSN</a>, <a href="https://publications.waset.org/abstracts/search?q=QoS" title=" QoS"> QoS</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title=" energy consumption"> energy consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=MAC%20protocol" title=" MAC protocol"> MAC protocol</a> </p> <a href="https://publications.waset.org/abstracts/54561/wireless-sensor-network-energy-efficient-and-qos-aware-mac-protocols-a-survey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54561.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">399</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">274</span> A Preliminary Investigation on Factors that Influence Malaysian Road User’s Close Following Behaviour</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siti%20Hikmah%20Musthar">Siti Hikmah Musthar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Saifizul"> Ahmad Saifizul</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Rehan%20Karim"> Mohamed Rehan Karim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamilah%20Mohamad"> Jamilah Mohamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Farah%20Fazlinda%20Mohamad"> Farah Fazlinda Mohamad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to look at the situation of close following behaviour from the introductory phase before conducting a profound investigation and discussion on this subject. Close following behaviour is known as behaviour during when drivers follow front vehicle with headways lower than two-second. As such, the study of close-following is important due to the degree of negative consequences this behaviour can cause commonly identified as rear-end collision especially when road safety is concerned. This paper presents a preliminary results of close-following behaviour among selected respondents (n=515) in Peninsular Malaysia at selected highways and federal roads. Respondents were interviewed with survey questions tending to examine their actual driving behaviour related to close-following and their perception towards the subject of close following. Selected findings (four selected questions) are discussed in this paper of which identified as essential for deliberation (as opposed to other questions in the survey questionnaire) as far as a preliminary discussion is concerned. Through the statistical test of one-way ANOVA, study found that gender of drivers is not significant to influence drivers to close follow but instead, type of vehicle the respondent drives had more significant to influence drivers to have tendency to perform close following behaviour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=close-following" title="close-following">close-following</a>, <a href="https://publications.waset.org/abstracts/search?q=driver%20behaviour" title=" driver behaviour"> driver behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=rear-end%20crash" title=" rear-end crash"> rear-end crash</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20safety" title=" road safety "> road safety </a> </p> <a href="https://publications.waset.org/abstracts/35228/a-preliminary-investigation-on-factors-that-influence-malaysian-road-users-close-following-behaviour" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35228.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">420</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">273</span> Flow and Heat Transfer over a Shrinking Sheet: A Stability Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anuar%20Ishak">Anuar Ishak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The characteristics of fluid flow and heat transfer over a permeable shrinking sheet is studied.

Five different states in the Peninsular of Malaysia that has been identified in showcasing the National Identity of Malaysia at each Petronas gas station, this also includes the Air Keroh in Melaka, Pasir Pekan in Kelantan, Pontian in Johor, Simpang Pulai in Perak, and also Wakaf Bharu in Terengganu. This project is to analyze the element of national identity that has been demonstrated at the Petronas's Mural. The ultimate aim of the mural is to let the community and local people to be aware about what Malaysians are consists and proud of and how everyone is able to connect with the idea through visual art. The method that is being explained in this research is by using visual data through research and also self-experience in collecting the visual data in identifying what images is considered as the national identity and idea development and visual analysis is being transferred based upon the visual data collection. In this stage, elements and principles of design will be the key in highlighting what is necessary for a work of art. In conclusion, visual image of the National Identity of Malaysia is able to connect to the audience from local and also to the people from outside the country to learn and understand the beauty and diversity of Malaysia as a unique country with art through the wall of five Petronas gas station. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community" title="community">community</a>, <a href="https://publications.waset.org/abstracts/search?q=fine%20art" title=" fine art"> fine art</a>, <a href="https://publications.waset.org/abstracts/search?q=mural%20art" title=" mural art"> mural art</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20identity" title=" national identity"> national identity</a> </p> <a href="https://publications.waset.org/abstracts/124086/national-identity-in-connecting-the-community-through-mural-art-for-petronas-dagangan-berhad" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124086.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">207</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">269</span> Noise Measurement and Awareness at Construction Site: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Feiruz%20Ab%27lah">Feiruz Ab'lah</a>, <a href="https://publications.waset.org/abstracts/search?q=Zarini%20Ismail"> Zarini Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Zaki%20Hassan"> Mohamad Zaki Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Nadia%20Mohd%20Bakhori"> Siti Nadia Mohd Bakhori</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Azlan%20Suhot"> Mohamad Azlan Suhot</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Yusof%20Md.%20Daud"> Mohd Yusof Md.

Previous studies indicated that the piling and concrete work was recorded as the main source that contributed to the highest level of noise among the others. Therefore, the aim of this study is to obtain the noise exposure during piling process and to determine the awareness of workers against noise pollution at the construction site. Initially, the reading of noise was obtained at construction site by using a digital sound level meter (SLM), and noise exposure to the workers was mapped. Readings were taken from four different distances; 5, 10, 15 and 20 meters from the piling machine. Furthermore, a set of questionnaire was also distributed to assess the knowledge regarding noise pollution at the construction site. The result showed that the mean noise level at 5m distance was more than 90 dB which exceeded the recommended level. Although the level of awareness regarding the effect of noise pollution is satisfactory, majority of workers (90%) still did not wear ear protecting device during work period. Therefore, the safety module guidelines related to noise pollution controls should be implemented to provide a safe working environment and prevent initial occupational hearing loss. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction" title="construction">construction</a>, <a href="https://publications.waset.org/abstracts/search?q=noise%20awareness" title=" noise awareness"> noise awareness</a>, <a href="https://publications.waset.org/abstracts/search?q=noise%20pollution" title=" noise pollution"> noise pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=piling%20machine" title=" piling machine"> piling machine</a> </p> <a href="https://publications.waset.org/abstracts/54543/noise-measurement-and-awareness-at-construction-site-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54543.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">384</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">268</span> Dual Solutions in Mixed Convection Boundary Layer Flow: A Stability Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anuar%20Ishak">Anuar Ishak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The mixed convection stagnation point flow toward a vertical plate is investigated.

In 2006, Libya imported LD 8 billion (US$ 6.25 billion) which composed of mainly machinery and transport equipment (49.3%), raw material (18%), and food products and live animals (13%). This represented about 10% of GDP. Thus, it is pertinent to investigate factors affecting the amount of Libyan imports. An econometric model representing the aggregate import demand for Libya was developed and estimated using the bounds test procedure, which based on an unrestricted error correction model (UECM). The data employed for the estimation was from 1970–2010. The results of the bounds test revealed that the volume of imports and its determinants namely real income, consumer price index and exchange rate are co-integrated. The findings indicate that the demand for imports is inelastic with respect to income, index price level and The exchange rate variable in the short run is statistically significant. In the long run, the income elasticity is elastic while the price elasticity and the exchange rate remains inelastic. This indicates that imports are important elements for Libyan economic growth in the long run. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=import%20demand" title="import demand">import demand</a>, <a href="https://publications.waset.org/abstracts/search?q=UECM" title=" UECM"> UECM</a>, <a href="https://publications.waset.org/abstracts/search?q=bounds%20test" title=" bounds test"> bounds test</a>, <a href="https://publications.waset.org/abstracts/search?q=Libya" title=" Libya "> Libya </a> </p> <a href="https://publications.waset.org/abstracts/1785/modelling-the-long-rune-of-aggregate-import-demand-in-libya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1785.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">361</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">266</span> Performance Evaluation of Distributed and Co-Located MIMO LTE Physical Layer Using Wireless Open-Access Research Platform</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ishak%20Suleiman">Ishak Suleiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Kamsani%20Samingan"> Ahmad Kamsani Samingan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeoh%20Chun%20Yeow"> Yeoh Chun Yeow</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Aziz%20Bin%20Abdul%20Rahman"> Abdul Aziz Bin Abdul Rahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we evaluate the benefits of distributed 4x4 MIMO LTE downlink systems compared to that of the co-located 4x4 MIMO LTE downlink system.

It affects and impinges on everyone's life as the roads shared by everyone. The most vulnerable victims were the road users who cater the roads every day. It is an appalling when World Health Organization reported that Malaysian road users were ranked worst in Asian countries with 23 deaths for every 100,000 of population over the span of 12 years (World Health Organization, 2009). From this report, it is found that speeding has contributed to 60% of all accidents in the country. Therefore, this study aims to elucidate on speeding matter that occur among road users in selected roads of Peninsular Malaysia. This study on the other hand, provides an insight understanding on the factors affecting behaviour of road users to speeding in selected roads of Peninsular Malaysia. To answer the study aims, 500 sets of questionnaires were distributed among 500 respondents in selected roads of Peninsular Malaysia to obtain their opinions on the matter. The respondents were from different demographics backgrounds to have fair explanation on the issue. The answers have been analysed using descriptive analysis. The results indicated psychological factors of road users appeared to be prominent in explaining road users’ behaviour to speeding. Male road users were also found dominant in speeding compared to female. Thus, this has increased their vulnerability to road injuries and deaths. These findings are very useful in order for us to improve our driving behaviour. Relevant authorities should also revise the existing countermeasures as well as designing the new countermeasures for the road users. It is nevertheless important to comprehend this speeding issue and factors associating it.

These models, which are able to recognize complex relationships between input and output sequences, are crucial for optimizing chatbot responses. Central to these mechanisms are neural attention weights that determine the focus of the model during sequence generation. Despite their widespread use, there remains a gap in the comparative analysis of different attention weighting functions within seq2seq models, particularly in the domain of chatbots using the Customer Support Twitter (CST) dataset. This study addresses this gap by evaluating four distinct attention-scoring functions—dot, multiplicative/general, additive, and an extended multiplicative function with a tanh activation parameter — in neural generative seq2seq models. Utilizing the CST dataset, these models were trained and evaluated over 10 epochs with the AdamW optimizer. Evaluation criteria included validation loss and BLEU scores implemented under both greedy and beam search strategies with a beam size of k=3. Results indicate that the model with the tanh-augmented multiplicative function significantly outperforms its counterparts, achieving the lowest validation loss (1.136484) and the highest BLEU scores (0.438926 under greedy search, 0.443000 under beam search, k=3). These results emphasize the crucial influence of selecting an appropriate attention-scoring function in improving the performance of seq2seq models for chatbots. Particularly, the model that integrates tanh activation proves to be a promising approach to improve the quality of chatbots in the customer support context. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attention%20weight" title="attention weight">attention weight</a>, <a href="https://publications.waset.org/abstracts/search?q=chatbot" title=" chatbot"> chatbot</a>, <a href="https://publications.waset.org/abstracts/search?q=encoder-decoder" title=" encoder-decoder"> encoder-decoder</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20generative%20attention" title=" neural generative attention"> neural generative attention</a>, <a href="https://publications.waset.org/abstracts/search?q=score%20function" title=" score function"> score function</a>, <a href="https://publications.waset.org/abstracts/search?q=sequence-to-sequence" title=" sequence-to-sequence"> sequence-to-sequence</a> </p> <a href="https://publications.waset.org/abstracts/176622/evaluating-generative-neural-attention-weights-based-chatbot-on-customer-support-twitter-dataset" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176622.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">258</span> Numerical Simulation of the Flow around Wing-In-Ground Effect (WIG) Craft</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Elbatran">A.

This paper investigates the aerodynamic characteristic of compound wing-in-ground effect (WIG) craft model. Drag coefficient, lift coefficient and Lift and drag ratio were studied numerically with respect to the ground clearance and the wing angle of attack. The modifications of the wing has been done in order to investigate the most suitable wing configuration that can increase the wing lift-to-drag ratio at low ground clearance. A numerical investigation was carried out in this research work using finite volume Reynolds-Averaged Navier-Stokes Equations (RANSE) code ANSYS CFX, Validation was carried out by using experiments. The experimental and the numerical results concluded that the lift to drag ratio decreased with the increasing of the ground clearance. <p class="card-text"><strong>Keywords:</strong> <a
