discusses the design, simulation results, and testing of a compact dual-band printed dipole antenna operating at frequencies of 916 MHz and 1.57 GHz for LoRa and GPS applications, respectively. The basic design of this antenna uses a linear dipole that operates at 916 MHz and 2.7 GHz. A small triangular-shaped linear balun has been developed as the matching network. Parasitic elements are employed to tune the second frequency to 1.57 GHz through a parametric study. Meanwhile, a stub is used to suppress the undesired 2.6 GHz frequency. This antenna is capable of operating on dual-frequency bands simultaneously with high efficiency in suppressing the unwanted frequency. The antenna exhibits the following parameters: return loss of -18.5 dB at 916 MHz and -14 dB at 1.57 GHz, VSWR of 1.25 at 868 MHz and 1.5 at 1.57 GHz, and gain of 2 dBi at 916 MHz and 2.75 dBi at 1.57 GHz. The radiation pattern of the antenna shows a directional E-plane and an omnidirectional H-plane at both frequencies. With its compact size and dual-band capability, this antenna demonstrates great potential for use in IoT applications that require both LoRa and GPS communication, particularly in applications where a small yet efficient form factor is essential. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dual%20band" title="dual band">dual band</a>, <a href="https://publications.waset.org/abstracts/search?q=dipole%20antenna" title=" dipole antenna"> dipole antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=parasitic%20elements" title=" parasitic elements"> parasitic elements</a>, <a href="https://publications.waset.org/abstracts/search?q=harmonic%20suppression" title=" harmonic suppression"> harmonic suppression</a>, <a href="https://publications.waset.org/abstracts/search?q=LoRa%20and%20Gps" title=" LoRa and Gps"> LoRa and Gps</a> </p> <a href="https://publications.waset.org/abstracts/194483/dual-band-loragps-dipole-antenna-with-harmonic-suppression-capability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194483.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">6</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">41</span> Instrument Development and Validation for Quality Early Childhood Curriculum in the Malaysian Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadiah%20Baharom">Sadiah Baharom</a>, <a href="https://publications.waset.org/abstracts/search?q=Che%20Nidzam%20Che%20Ahmad"> Che Nidzam Che Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Saipol%20Barin%20Ramli"> Saipol Barin Ramli</a>, <a href="https://publications.waset.org/abstracts/search?q=Asmayati%20Yahaya"> Asmayati Yahaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Sopia%20Md%20Yassin"> Sopia Md Yassin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The early childhood care and education (ECCE) in Malaysia aspire to develop children who are intellectually, emotionally, physically and spiritually balanced. This aspiration can only materialise if the early childhood program developed comprehensive and is of high quality comparable to international standards. As such, there is a pressing need to assess the quality of the program in an all-encompassing manner. The overall research project aims at developing a comprehensive and integrated model of high-quality Malaysian ECCE. One of the major objectives of this project is to assess and evaluate the scope and quality of the existing ECCE programs in Malaysia. To this end, a specific aspect of this objective is to develop and validate an instrument to assess and evaluate the ECCE curriculum of the country. Thus this paper describes the development and validation of an instrument to explore the quality of early childhood care and education curriculum currently implemented in the country’s ECCE centres. The generation of the constructs and items were based on a set of criteria mapped against existing ECCE practice, document analyses, expert interviews and panel discussions. The items went through expert validation and were field tested on 597 ECCE teachers. The data obtained went through an exploratory factor analysis to validate the constructs of the instrument followed by reliability studies on internal consistency based on the Cronbach Alpha values. The final set of items for the ECCE curriculum instrument, earmarked for the main study, consists of four constructs namely philosophy and core values, curriculum content, curriculum review and unique features. Each construct consists of between 21 to 3 items with a total of 36 items in all. The reliability coefficients for each construct range from 0.65 to 0.961. These values are within the acceptable limits for a reliable instrument to be used in the main study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=early%20childhood%20and%20care%20education" title="early childhood and care education">early childhood and care education</a>, <a href="https://publications.waset.org/abstracts/search?q=instrument%20development" title=" instrument development"> instrument development</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability%20studies" title=" reliability studies"> reliability studies</a>, <a href="https://publications.waset.org/abstracts/search?q=validity%20studies" title=" validity studies"> validity studies</a> </p> <a href="https://publications.waset.org/abstracts/72594/instrument-development-and-validation-for-quality-early-childhood-curriculum-in-the-malaysian-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72594.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">201</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">40</span> Where Is the Sultan of Aceh?

The political powers that were once unified in their struggle against Indonesian Government prior to this agreement have now become divided due to differences in political and economic interests. Using descriptive analysis and intellectual discourse, this paper proposes that the Aceh Sultanate be revived as an attempt to unite these divided political powers and to curtail potential conflicts in the area. This proposal is based on three assumptions. First, the Aceh Sultanate is the only Sultanate in Sumatera that did not fall victim to the social revolution post 1945 proclamation of independence. Second, the Acehnese still acknowledge the Sultanate as a sovereign political power even though it was defeated by the Dutch in 1904. Third, there are emotional, historical and cultural ties between the Acehnese and the Sultanate as they still perceived them to be their patron. Consequently, the Sultanate is the unifying element of all political powers in the area. This, however, is not an attempt to reinstate feudalism in Aceh. It only seeks to facilitate the political reconciliation process in Aceh Darussalam founded on sociological and historical background of locals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sultanate%20Aceh" title="Sultanate Aceh">Sultanate Aceh</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20reconciliation" title=" political reconciliation"> political reconciliation</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20power" title=" political power"> political power</a>, <a href="https://publications.waset.org/abstracts/search?q=patron-client" title=" patron-client"> patron-client</a> </p> <a href="https://publications.waset.org/abstracts/20677/where-is-the-sultan-of-aceh-reconsidering-the-return-of-the-aceh-sultanate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20677.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">265</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Generating Arabic Fonts Using Rational Cubic Ball Functions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fakharuddin%20Ibrahim">Fakharuddin Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamaludin%20Md.%20Ali"> Jamaludin Md.

Various confinements systems, namely triangular, circular and rectangular with the size of 50, 100, and 150 mm, and with a depth of 10 mm, were embedded in soil samples at slope angle of 60°. The observed soil mass losses for the confined soil systems were much smaller than those from unconfined system. As a result, the size of confinement and rainfall intensity have a direct effect on the soil mass loss. The triangular and rectangular confinement systems showed the lowest and highest soil loss masses, respectively. The slopes also failed much faster in the unconfined system than in the confined slope. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=erosion%20control" title="erosion control">erosion control</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20confinement" title=" soil confinement"> soil confinement</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20erosion" title=" soil erosion"> soil erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=slope%20stability" title=" slope stability"> slope stability</a> </p> <a href="https://publications.waset.org/abstracts/6822/soil-mass-loss-reduction-during-rainfalls-by-reinforcing-the-slopes-with-the-surficial-confinement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6822.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">842</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Rim Size Optimization Using Mathematical Modelling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Tan">M.

As the size of the rims or wheels played an important role in influencing the way of car handles around turns, this paper aims to present the optimality of rim size that drivers should have known while changing their rim. There are three factors that drivers should have considered while changing their rim: rim size, its weight and material of which they are made. Using mathematical analysis, this paper will focus on only one factor, which is rim size. Factors that are considered in calculating the optimum rim size are the vehicle rim radius, tire height and weight, and aspect ratio. This paper has found that there are limitations in percentage change in rim size from the original tire size. Failure to have the right offset size may cause problems in maneuvering the vehicle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mathematical%20analysis" title="mathematical analysis">mathematical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=optimum%20wheel%20size" title=" optimum wheel size"> optimum wheel size</a>, <a href="https://publications.waset.org/abstracts/search?q=percentage%20change" title=" percentage change"> percentage change</a>, <a href="https://publications.waset.org/abstracts/search?q=custom%20wheel" title=" custom wheel"> custom wheel</a> </p> <a href="https://publications.waset.org/abstracts/8523/rim-size-optimization-using-mathematical-modelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8523.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">492</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Microcrystalline Cellulose (MCC) from Oil Palm Empty Fruit Bunch (EFB) Fiber via Simultaneous Ultrasonic and Alkali Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ridzuan%20Ramli">Ridzuan Ramli</a>, <a href="https://publications.waset.org/abstracts/search?q=Norhafzan%20Junadi"> Norhafzan Junadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20D.H.%20Beg"> Mohammad D.H.

In order to isolate the cellulose, the chlorination method was carried out. Then, the MCC was prepared by simultaneous ultrasonic and alkali treatment from the isolated α-cellulose. Based on mass balance calculation, the yields for MCC obtained from EFB was 44%. For fiber characterization, it is observed that the chemical composition of the hemicellulose and lignin for all samples decreased while composition for cellulose increased. The structural property of the MCC was studied by X-ray diffraction (XRD) method and the result shows that the MCC produced is a cellulose-I polymorph, with 73% crystallinity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oil%20palm%20empty%20fruit%20bunch" title="oil palm empty fruit bunch">oil palm empty fruit bunch</a>, <a href="https://publications.waset.org/abstracts/search?q=microcrystalline%20cellulose" title=" microcrystalline cellulose"> microcrystalline cellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonic" title=" ultrasonic"> ultrasonic</a>, <a href="https://publications.waset.org/abstracts/search?q=alkali%20treatment" title=" alkali treatment"> alkali treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=x-ray%20diffraction" title=" x-ray diffraction"> x-ray diffraction</a> </p> <a href="https://publications.waset.org/abstracts/17460/microcrystalline-cellulose-mcc-from-oil-palm-empty-fruit-bunch-efb-fiber-via-simultaneous-ultrasonic-and-alkali-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17460.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">414</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> A Study on the Response of Vacuum Consolidation on Soft Clay in Combination with Prefabricated Vertical Drain (PVD), Embankment and Surcharge Preloading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sharmeelee%20Subramaniam">Sharmeelee Subramaniam</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhd%20Harris%20Ramli"> Muhd Harris Ramli</a>, <a href="https://publications.waset.org/abstracts/search?q=Fauziah%20Ahmad"> Fauziah Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The application of vacuum pressure to accelerate ground consolidation has been growing significantly in recent years.

Sump system is an unsteady process owing to the level response. Sump level shall be monitored carefully by using a good controller to avoid overflow. The current conventional controllers would not be able to solve problems with large time delay and nonlinearities, Fuzzy Logic controller is tested to prove its ability in solving the listed problems of slurry sump. Therefore, in order to justify the effectiveness and reliability of these controllers, simulation of the sump system was created by using MATLAB and the results were compared. According to the result obtained, instead of Proportional-Integral (PI) and Proportional-Integral and Derivative (PID), Fuzzy Logic controller showed the best result by offering quick response of 0.32 s for step input and 5 s for pulse generator, by producing small Integral Absolute Error (IAE) values that are 0.66 and 0.36 respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fuzzy" title="fuzzy">fuzzy</a>, <a href="https://publications.waset.org/abstracts/search?q=sump" title=" sump"> sump</a>, <a href="https://publications.waset.org/abstracts/search?q=level" title=" level"> level</a>, <a href="https://publications.waset.org/abstracts/search?q=controller" title=" controller"> controller</a> </p> <a href="https://publications.waset.org/abstracts/75241/fuzzy-logic-and-control-strategies-on-a-sump" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75241.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">243</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Mechanical Properties of Self-Compacting Concrete with Three-Dimensional Steel Fibres</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeffri%20Ramli">Jeffri Ramli</a>, <a href="https://publications.waset.org/abstracts/search?q=Brabha%20Nagaratnam"> Brabha Nagaratnam</a>, <a href="https://publications.waset.org/abstracts/search?q=Keerthan%20Poologanathan"> Keerthan Poologanathan</a>, <a href="https://publications.waset.org/abstracts/search?q=Wai%20Ming%20Cheung"> Wai Ming Cheung</a>, <a href="https://publications.waset.org/abstracts/search?q=Thadshajini%20Suntharalingham"> Thadshajini Suntharalingham</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fiber-reinforced self-compacting concrete (FRSCC) combines the benefits of SCC of high flowability and randomly dispersed short fibres together in one single concrete. Fibres prevent brittle behaviour and improve several mechanical properties of SCC. In this paper, an experimental investigation of the effect of three-dimensional (3D) fibres on the mechanical properties of SCC has been conducted. Seven SCC mixtures, namely SCC with no fibres as a reference mix, and six 3D steel fibre reinforced SCC mixes were prepared. Two different sizes of 3D steel fibres with perimeters of 115 mm and 220 mm at different fibre contents of 1%, 2%, and 3% (by cement weight) were considered. The mechanical characteristics were obtained through compressive, splitting tensile, and flexural strength tests. The test results revealed that the addition of 3D fibres improves the mechanical properties of SCC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self-compacting%20concrete" title="self-compacting concrete">self-compacting concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=three-dimensional%20steel%20fibres" title=" three-dimensional steel fibres"> three-dimensional steel fibres</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=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=splitting%20tensile%20strength" title=" splitting tensile strength"> splitting tensile strength</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural%20strength" title=" flexural strength"> flexural strength</a> </p> <a href="https://publications.waset.org/abstracts/130889/mechanical-properties-of-self-compacting-concrete-with-three-dimensional-steel-fibres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130889.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">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Assessment of Bridge Performance with Laminated versus Spring Seismic Isolation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Z.%20Ramli">M.

According to thermal stability, the NCC obtained show remarkable sign of high thermal stability compared to EFB fiber and EFB pulp. However, as the hydrolysis time increase, the thermal stability of NCC was deceased. As in conclusion, the NCC can be prepared by using ultrasound assisted acid hydrolysis.

Specifically, the internal governance structure of corporate Islamic endowment, or waqf, is being analysed. The purposes of waqf are to provide continuous charity that could generate perpetual income flow for the needy. This study is based on the principle of MCCG 2012, Shariah Governance Framework and charity governance. This study utilises publicly available data to examine the internal governance structure of a corporate waqf. This study finds that the Islamic philanthropic Institution practices, to some extent, have a sound governance structure to discharge their transparency and accountability. Furthermore, findings also showed that though governance structure is in place, most of the structures are not disclosed in the annual reports of the company.

Towards year 2018, Malaysia is in the way of planning to get the halal certification for biomedical device in order to cater the needs of Muslims and non-Muslims in Malaysia. However, the use of gelatins in tissue engineering are mostly derived from non-halal sources. Currently, gelatin production mostly comes from mammalian gelatin sources. Moreover, within these past years, just a few studies of the uses of gelatin in tissue engineering from halal perspective has been studied. Thus, this paper aims to give overview of the use of gelatin from different sources from halal perspectives. This review also discussing the current status of halal for the emerging biomedical devices. In addition, the different sources of gelatin used in tissue engineering are being identified and provides better alternatives for halal gelatin. Cold- water fish skin gelatin could be an effective alternative to substitute the mammalian sources. Therefore, this review is important because the information about the halal biomedical devices will delighted Muslim consumers and give better insight of halal gelatin in tissue engineering application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomedical%20device" title="biomedical device">biomedical device</a>, <a href="https://publications.waset.org/abstracts/search?q=gelatin" title=" gelatin"> gelatin</a>, <a href="https://publications.waset.org/abstracts/search?q=halal" title=" halal"> halal</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20graft" title=" skin graft"> skin graft</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue%20engineering" title=" tissue engineering"> tissue engineering</a> </p> <a href="https://publications.waset.org/abstracts/85056/the-use-of-gelatin-in-biomedical-engineering-halal-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85056.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">23</span> Effect Different Moisture States of Surface-treated Recycled Concrete Aggregate on Properties of Fresh and Hardened Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sallehan%20Ismail">Sallehan Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahyuddin%20Ramli"> Mahyuddin Ramli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examined the properties of fresh and hardened concretes as influenced by the moisture state of the coarse recycled concrete aggregates (RCA) after surface treatment.

The treated coarse RCA was maintained in three controlled moisture states, namely, air-dried, oven-dried, and saturated surface-dried (SSD), prior to its use in a concrete mix. The physical properties of coarse RCA were evaluated after surface treatment during the first phase of the experiment to determine the density and the water absorption characteristics of the RCA. The second phase involved the evaluation of the slump, slump loss, density, and compressive strength of the concretes that were prepared with different proportions of natural and treated coarse RCA. Controlling the moisture state of the coarse RCA after surface treatment was found to significantly influence the properties of the fresh and hardened concretes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=moisture%20state" title="moisture state">moisture state</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20concrete%20aggregate" title=" recycled concrete aggregate"> recycled concrete aggregate</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20treatment" title=" surface treatment"> surface treatment</a> </p> <a href="https://publications.waset.org/abstracts/4188/effect-different-moisture-states-of-surface-treated-recycled-concrete-aggregate-on-properties-of-fresh-and-hardened-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4188.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">263</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> The Effect of Gross Vehicle Weight on the Stability of Heavy Vehicle during Cornering </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nurzaki%20Ikhsan">Nurzaki Ikhsan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Saifizul%20Abdullah"> Ahmad Saifizul Abdullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahizar%20Ramli"> Rahizar Ramli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the functions of the commercial heavy vehicle is to safely and efficiently transport goods and people. Due to its size and carrying capacity, it is important to study the vehicle dynamic stability during cornering. Study has shown that there are a number of overloaded heavy vehicles or permissible gross vehicle weight (GVW) violations recorded at selected areas in Malaysia assigned by its type and category. Thus, the objective of this study is to investigate the correlation and effect of the GVW on heavy vehicle stability during cornering event using simulation. Various selected heavy vehicle types and category are simulated using IPG/Truck Maker® with different GVW and road condition (coefficient of friction of road surface), while the speed, driver characteristic, center of gravity of load and road geometry are constant. Based on the analysis, the relationship between GVW and lateral acceleration were established. As expected, on the same value of coefficient of friction, the maximum lateral acceleration would be increased as the GVW increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20vehicle" title="heavy vehicle">heavy vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20safety" title=" road safety"> road safety</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20stability" title=" vehicle stability"> vehicle stability</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20acceleration" title=" lateral acceleration"> lateral acceleration</a>, <a href="https://publications.waset.org/abstracts/search?q=gross%20vehicle%20weight" title=" gross vehicle weight"> gross vehicle weight</a> </p> <a href="https://publications.waset.org/abstracts/29769/the-effect-of-gross-vehicle-weight-on-the-stability-of-heavy-vehicle-during-cornering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29769.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">532</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Architectural Building Safety and Health Performance Model for Stratified Low-Cost Housing: Education and Management Tool for Building Managers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zainal%20Abidin%20Akasah">Zainal Abidin Akasah</a>, <a href="https://publications.waset.org/abstracts/search?q=Maizam%20Alias"> Maizam Alias</a>, <a href="https://publications.waset.org/abstracts/search?q=Azuin%20Ramli"> Azuin Ramli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The safety and health performances aspects of a building are the most challenging aspect of facility management. It requires a deep understanding by the building managers on the factors that contribute to health and safety performances. This study attempted to develop an explanatory architectural safety performance model for stratified low-cost housing in Malaysia. The proposed Building Safety and Health Performance (BSHP) model was tested empirically through a survey on 308 construction practitioners using Partial Least Squares (PLS) and Structural Equation Modelling (SEM) tool. Statistical analysis results supports the conclusion that architecture, building services, external environment, management approaches and maintenance management have positive influence on safety and health performance of stratified low-cost housing in Malaysia. The findings provide valuable insights for construction industry to introduce BSHP model in the future where the model could be used as a guideline for training purposes of managers and better planning and implementation of building management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20management" title="building management">building management</a>, <a href="https://publications.waset.org/abstracts/search?q=stratified%20low-cost%20housing" title=" stratified low-cost housing"> stratified low-cost housing</a>, <a href="https://publications.waset.org/abstracts/search?q=safety" title=" safety"> safety</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20model" title=" health model"> health model</a> </p> <a href="https://publications.waset.org/abstracts/25509/architectural-building-safety-and-health-performance-model-for-stratified-low-cost-housing-education-and-management-tool-for-building-managers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25509.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">555</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Approximating Maximum Speed on Road from Curvature Information of Bezier Curve</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Yushalify%20Misro">M.

Both algorithms join cubic Bezier curve segment smoothly to generate the path. Some of the useful properties of Bezier are curvature. In mathematics, the curvature is the amount by which a geometric object deviates from being flat, or straight in the case of a line. Another extrinsic example of curvature is a circle, where the curvature is equal to the reciprocal of its radius at any point on the circle. The smaller the radius, the higher the curvature thus the vehicle needs to bend sharply. In this study, we use Bezier curve to fit highway-like curve. We use the different approach to finding the best approximation for the curve so that it will resemble highway-like curve. We compute curvature value by analytical differentiation of the Bezier Curve. We will then compute the maximum speed for driving using the curvature information obtained. Our research works on some assumptions; first the Bezier curve estimates the real shape of the curve which can be verified visually. Even, though, the fitting process of Bezier curve does not interpolate exactly on the curve of interest, we believe that the estimation of speed is acceptable. We verified our result with the manual calculation of the curvature from the map. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=speed%20estimation" title="speed estimation">speed estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=path%20constraints" title=" path constraints"> path constraints</a>, <a href="https://publications.waset.org/abstracts/search?q=reference%20trajectory" title=" reference trajectory"> reference trajectory</a>, <a href="https://publications.waset.org/abstracts/search?q=Bezier%20curve" title=" Bezier curve"> Bezier curve</a> </p> <a href="https://publications.waset.org/abstracts/36228/approximating-maximum-speed-on-road-from-curvature-information-of-bezier-curve" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36228.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">375</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> The Pursuit of Marital Sustainability Inspiring by Successful Matrimony of Two Distinguishable Indonesian Ethnics as a Learning Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mutiara%20Amalina%20Khairisa">Mutiara Amalina Khairisa</a>, <a href="https://publications.waset.org/abstracts/search?q=Purnama%20Arafah"> Purnama Arafah</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahayu%20Listiana%20Ramli"> Rahayu Listiana Ramli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, so many cases of divorce increasingly occur.

HME5, a prenylflavanoid has been isolated from local medicinal plant. This compound has been reported to possess a broad spectrum of biological activities including anticancer property. However, the potential of HME5 as an antiproliferative and cytotoxic agent on an ovarian cancer cells has not yet been investigated. In this present study, we examined the antiproliferative and cytotoxic effect of HME5 on Caov-3 (Human Ovarian Adenocarcinoma) cell line by using 3-[4,5-dimethylthizol-2-y]-2,5-diphenyltetrazolium bromide (MTT) assay, Acridine orange and propidium Iodide (AOPi) and cell cycle analysis study. HME5 has shown to inhibit Caov-3 in a time-dependent manner with the IC50 values of 5µg/ml, 2µg/ml and 1µg/ml after 24h, 48h and 72h treatment, respectively. Morphological study from AOPi analysis showed that HME5 induced apoptosis after 24 and 48h post-treatment. Nevertheless, HME5 exhibited cell cycle arrest at G1 phase as indicated in flow cytometry cell cycle profiling. In conclusion, HME5 inhibited proliferation of Caov-3 through induction of apoptosis and cell cycle arrest at G1 phase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title="apoptosis">apoptosis</a>, <a href="https://publications.waset.org/abstracts/search?q=prenylflavanoid" title=" prenylflavanoid"> prenylflavanoid</a>, <a href="https://publications.waset.org/abstracts/search?q=ovarian%20cancer" title=" ovarian cancer"> ovarian cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=HME5" title=" HME5 "> HME5 </a> </p> <a href="https://publications.waset.org/abstracts/13503/a-prenylflavanoid-hme5-with-antiproliferative-activity-in-human-ovarian-cancer-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13503.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">461</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Preparation and Characterization of Modified ZnO Incorporated into Mesoporous MCM-22 Catalysts and Their Catalytic Performances of Crude Jatropha Oil to Biodiesel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bashir%20Abubakar%20Abdulkadir">Bashir Abubakar Abdulkadir</a>, <a href="https://publications.waset.org/abstracts/search?q=Anita%20Ramli"> Anita Ramli</a>, <a href="https://publications.waset.org/abstracts/search?q=Lim%20Jun%20Wei"> Lim Jun Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoshimitsu%20Uemura"> Yoshimitsu Uemura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the ZnO/MCM-22 catalyst with different ZnO loading were prepared using conventional wet impregnation process and the catalyst activity was tested for biodiesel production from Jatropha oil. The effects of reaction parameters with regards to catalyst activity were investigated. The synthesized catalysts samples were then characterized by X-ray diffraction (XRD) for crystal phase, Brunauer–Emmett–Teller (BET) for surface area, pore volume and pore size, Field Emission Scanning electron microscope attached to energy dispersive x-ray (FESEM/EDX) for morphology and elemental composition and TPD (NH3 and CO2) for basic and acidic properties of the catalyst. The XRD spectra couple with the EDX result shows the presence of ZnO in the catalyst confirming the positive intercalation of the metal oxide into the mesoporous MCM-22. The synthesized catalyst was confirmed to be mesoporous according to BET findings. Also, the catalysts can be considered as a bifunctional catalyst based on TPD outcomes. Transesterification results showed that the synthesized catalyst was highly efficient and effective to be used for biodiesel production from low grade oil such as Jatropha oil and other industrial application where the high fatty acid methyl ester (FAMEs) yield was achieved at moderate reaction conditions. It was also discovered that the catalyst can be used more than five (5) runs with little deactivation confirming the catalyst to be highly active and stable to the heat of reaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MCM-22" title="MCM-22">MCM-22</a>, <a href="https://publications.waset.org/abstracts/search?q=synthesis" title=" synthesis"> synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=transesterification" title=" transesterification"> transesterification</a>, <a href="https://publications.waset.org/abstracts/search?q=ZnO" title=" ZnO"> ZnO</a> </p> <a href="https://publications.waset.org/abstracts/80401/preparation-and-characterization-of-modified-zno-incorporated-into-mesoporous-mcm-22-catalysts-and-their-catalytic-performances-of-crude-jatropha-oil-to-biodiesel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80401.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">208</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">16</span> Temporal Variation of Shorebirds Population in Two Different Mudflats Areas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Norazlimi">N.

Direct observation technique (using binoculars and video camera) was applied to record the presence of bird species in the sampling sites from August 2013 until July 2014. A total of 32 species of shorebird were recorded during both migratory and non-migratory seasons. Of these, eleven species (47.8%) are migrants, six species (26.1%) have both migrant and resident populations, four species (17.4%) are vagrants and two species (8.7%) are residents. The compositions of the birds differed significantly in all months (χ2=84.35, p<0.001). There is a significant difference in avian abundance between migratory and non-migratory seasons (Mann-Whitney, t=2.39, p=0.036). The avian abundance were differed significantly in Jeram and Remis Beaches during migratory periods (t=4.39, p=0.001) but not during non-migratory periods (t=0.78, p=0.456). Shorebird diversity was also affected by tidal cycle. There is a significance difference between high tide and low tide (Mann-Whitney, t=78.0, p<0.005). Frequency of disturbance also affected the shorebird distribution (Mann-Whitney, t=57.0, p= 0.0134). Therefore, this study concluded that tides and disturbances are two factors that affecting temporal distribution of shorebird in mudflats area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title="biodiversity">biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution" title=" distribution"> distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=migratory%20birds" title=" migratory birds"> migratory birds</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20observation" title=" direct observation"> direct observation</a> </p> <a href="https://publications.waset.org/abstracts/16862/temporal-variation-of-shorebirds-population-in-two-different-mudflats-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16862.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">391</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Assessing Flood Risk and Mapping Inundation Zones in the Kelantan River Basin: A Hydrodynamic Modeling Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatemehsadat%20Mortazavizadeh">Fatemehsadat Mortazavizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Amin%20Dehghani"> Amin Dehghani</a>, <a href="https://publications.waset.org/abstracts/search?q=Majid%20Mirzaei"> Majid Mirzaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurulhuda%20Binti%20Mohammad%20Ramli"> Nurulhuda Binti Mohammad Ramli</a>, <a href="https://publications.waset.org/abstracts/search?q=Adnan%20Dehghani"> Adnan Dehghani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flood is Malaysia's most common and serious natural disaster. Kelantan River Basin is a tropical basin that experiences a rainy season during North-East Monsoon from November to March. It is also one of the hardest hit areas in Peninsular Malaysia during the heavy monsoon rainfall. Considering the consequences of the flood events, it is essential to develop the flood inundation map as part of the mitigation approach. In this study, the delineation of flood inundation zone in the area of Kelantan River basin using a hydrodynamic model is done by HEC-RAS, QGIS and ArcMap. The streamflow data has been generated with the weather generator based on the observation data. Then, the data is statistically analyzed with the Extreme Value (EV1) method for 2-, 5-, 25-, 50- and 100-year return periods. The minimum depth, maximum depth, mean depth, and the standard deviation of all the scenarios, including the OBS, are observed and analyzed. Based on the results, generally, the value of the data increases with the return period for all the scenarios. However, there are certain scenarios that have different results, which not all the data obtained are increasing with the return period. Besides, OBS data resulted in the middle range within Scenario 1 to Scenario 40. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flood%20inundation" title="flood inundation">flood inundation</a>, <a href="https://publications.waset.org/abstracts/search?q=kelantan%20river%20basin" title=" kelantan river basin"> kelantan river basin</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrodynamic%20model" title=" hydrodynamic model"> hydrodynamic model</a>, <a href="https://publications.waset.org/abstracts/search?q=extreme%20value%20analysis" title=" extreme value analysis"> extreme value analysis</a> </p> <a href="https://publications.waset.org/abstracts/175709/assessing-flood-risk-and-mapping-inundation-zones-in-the-kelantan-river-basin-a-hydrodynamic-modeling-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175709.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">70</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Development of Total Maximum Daily Load Using Water Quality Modelling as an Approach for Watershed Management in Malaysia </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20A.%20Che%20Osmi">S.

However, increasing activities in a river has grown the sources of pollutant enters the water bodies, and degraded the water quality of the river. It becomes a challenge to develop an effective river management to ensure the water sources of the river are well managed and regulated. In Malaysia, several approaches for river management have been implemented such as Integrated River Basin Management (IRBM) program for coordinating the management of resources in a natural environment based on river basin to ensure their sustainability lead by Department of Drainage and Irrigation (DID), Malaysia. Nowadays, Total Maximum Daily Load (TMDL) is one of the best approaches for river management in Malaysia. TMDL implementation is regulated and implemented in the United States. A study on the development of TMDL in Malacca River has been carried out by doing water quality monitoring, the development of water quality model by using Environmental Fluid Dynamic Codes (EFDC), and TMDL implementation plan. The implementation of TMDL will help the stakeholders and regulators to control and improve the water quality of the river. It is one of the good approaches for river management in Malaysia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EFDC" title="EFDC">EFDC</a>, <a href="https://publications.waset.org/abstracts/search?q=river%20management" title=" river management"> river management</a>, <a href="https://publications.waset.org/abstracts/search?q=TMDL" title=" TMDL"> TMDL</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality%20modelling" title=" water quality modelling"> water quality modelling</a> </p> <a href="https://publications.waset.org/abstracts/57750/development-of-total-maximum-daily-load-using-water-quality-modelling-as-an-approach-for-watershed-management-in-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57750.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">328</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Corrosion Inhibition of Brass in Phosphoric Acid Solution by 2-(5-Methyl-2-Nitro-1H-Imidazol-1-Yl) Ethyl Benzoate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Khrifou">R.

Its effect on brass corrosion in 1.0 M H₃PO₄ solution was investigated by using electrochemical measurements coupled with X-ray diffraction analysis (XRD), Scanning electron microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDX). The polarization measurements showed that the IMDZ-B acts as a mixed-type inhibitor. Indeed, it is found that the IMDZ-B compound is a very good inhibitor, and its inhibition efficiency increases with concentration to reach a maximum of 99.5 % at 10-³ M. In addition, the obtained electrochemical parameters from impedance indicated that the IMDZ-B molecules act by adsorption on metallic surfaces. This adsorption was found to obey Langmuir’s adsorption isotherm. However, the temperature effect on the performance of IMDZ-B was also studied. It is found that the IMDZ-B takes its performance at high temperatures. In addition, the obtained kinetic and thermodynamic parameters showed that the IMDZ-B molecules act via two adsorption modes, physisorption and chemisorptions, and its process is endothermic and spontaneous. Finally, the XRD and SEM/EDX analyses confirmed the electrochemical obtained results. <p class="card-text"><strong>Keywords:</strong> <a
