Programming code is ordinarily obfuscated to protect the intellectual property (IP) and prevent the attacker from reverse engineering (RE) a copyrighted software program. Obfuscation may involve encrypting some or all the code, transforming out potentially revealing data, renaming useful classes and variables (identifiers) names to meaningless labels, or adding unused or meaningless code to an application binary. Obfuscation techniques were not performing effectively recently as the reversing tools are able to break the obfuscated code. We propose in this paper a hybrid obfuscation technique that contains three approaches of renaming. Experimentation was conducted to test the effectiveness of the proposed technique. The experimentation has presented a promising result, where the reversing tools were not able to read the code. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intellectual%20property" title="intellectual property">intellectual property</a>, <a href="https://publications.waset.org/abstracts/search?q=obfuscation" title=" obfuscation"> obfuscation</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20security" title=" software security"> software security</a>, <a href="https://publications.waset.org/abstracts/search?q=reverse%20engineering" title=" reverse engineering"> reverse engineering</a> </p> <a href="https://publications.waset.org/abstracts/116796/hybrid-obfuscation-technique-for-reverse-engineering-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116796.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">512</span> Facile, Cost Effective and Green Synthesis of Graphene in Alkaline Aqueous Solution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Illyas%20Isa">Illyas Isa</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Nur%20Akmar%20Mohd%20Yazid"> Siti Nur Akmar Mohd Yazid</a>, <a href="https://publications.waset.org/abstracts/search?q=Norhayati%20Hashim"> Norhayati Hashim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We report a simple, green and cost effective synthesis of graphene via chemical reduction of graphene oxide in alkaline aqueous solution. Extensive characterizations have been studied to confirm the formation of graphene in sodium carbonate solution. Cyclic voltammetry was used to study the electrochemical properties of the prepared graphene-modified glassy carbon electrode using potassium ferricyanide as a redox probe. Based on the result, with the addition of graphene to the glassy carbon electrode the current flow increases and the peak also broadens as compared to graphite and graphene oxide. This method is fast, cost effective, and green as nontoxic solvents are used which will not result in contamination of the products. Thus, this method can serve for the preparation of graphene which can be effectively used in sensors, electronic devices and supercapacitors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20reduction" title="chemical reduction">chemical reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical" title=" electrochemical"> electrochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene" title=" graphene"> graphene</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20synthesis" title=" green synthesis"> green synthesis</a> </p> <a href="https://publications.waset.org/abstracts/45193/facile-cost-effective-and-green-synthesis-of-graphene-in-alkaline-aqueous-solution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45193.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">337</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">511</span> The Utilization of Particle Swarm Optimization Method to Solve Nurse Scheduling Problem </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norhayati%20Mohd%20Rasip">Norhayati Mohd Rasip</a>, <a href="https://publications.waset.org/abstracts/search?q=Abd.%20Samad%20Hasan%20Basari"> Abd.

In the case of nurse scheduling, to set up the working time table for them is time consuming and complicated, which consider many factors including rules, regulation and human factor. The scenario is more complicated since most nurses are women which have personnel constraints and maternity leave factors. The undesirable schedule can affect the nurse productivity, social life and the absenteeism can significantly as well affect patient's life. This paper aimed to enhance the scheduling process by utilizing the particle swarm optimization in order to solve nurse scheduling problem. The result shows that the generated multiple initial schedule is fulfilled the requirements and produces the lowest cost of constraint violation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nurse%20scheduling" title="nurse scheduling">nurse scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimisation" title=" particle swarm optimisation"> particle swarm optimisation</a>, <a href="https://publications.waset.org/abstracts/search?q=nurse%20rostering" title=" nurse rostering"> nurse rostering</a>, <a href="https://publications.waset.org/abstracts/search?q=hard%20and%20soft%20constraint" title=" hard and soft constraint"> hard and soft constraint</a> </p> <a href="https://publications.waset.org/abstracts/30425/the-utilization-of-particle-swarm-optimization-method-to-solve-nurse-scheduling-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30425.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">372</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">510</span> Prediction of Changes in Optical Quality by Tissue Redness after Pterygium Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Radzi%20Hilmi">Mohd Radzi Hilmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Zulfaezal%20Che%20Azemin"> Mohd Zulfaezal Che Azemin</a>, <a href="https://publications.waset.org/abstracts/search?q=Khairidzan%20Mohd%20Kamal"> Khairidzan Mohd Kamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Azrin%20Esmady%20Ariffin"> Azrin Esmady Ariffin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Izzuddin%20Mohd%20Tamrin"> Mohd Izzuddin Mohd Tamrin</a>, <a href="https://publications.waset.org/abstracts/search?q=Norfazrina%20Abdul%20Gaffur"> Norfazrina Abdul Gaffur</a>, <a href="https://publications.waset.org/abstracts/search?q=Tengku%20Mohd%20Tengku%20Sembok"> Tengku Mohd Tengku Sembok</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: The purpose of this study is to predict optical quality changes after pterygium surgery using tissue redness grading. Methods: Sixty-eight primary pterygium participants were selected from patients who visited an ophthalmology clinic. We developed a semi-automated computer program to measure the pterygium fibrovascular redness from digital pterygium images. The outcome of this software is a continuous scale grading of 1 (minimum redness) to 3 (maximum redness). The region of interest (ROI) was selected manually using the software. Reliability was determined by repeat grading of all 68 images and its association with contrast sensitivity function (CSF) and visual acuity (VA) was examined. Results: The mean and standard deviation of redness of the pterygium fibrovascular images was 1.88 ± 0.55. Intra- and inter-grader reliability estimates were high with intraclass correlation ranging from 0.97 to 0.98. The new grading was positively associated with CSF (p<0.01) and VA (p<0.01). The redness grading was able to predict 25% and 23% of the variance in the CSF and the VA respectively. Conclusions: The new grading of pterygium fibrovascular redness can be reliably measured from digital images and show a good correlation with CSF and VA. The redness grading can be used in addition to the existing pterygium grading. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contrast%20sensitivity" title="contrast sensitivity">contrast sensitivity</a>, <a href="https://publications.waset.org/abstracts/search?q=pterygium" title=" pterygium"> pterygium</a>, <a href="https://publications.waset.org/abstracts/search?q=redness" title=" redness"> redness</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20acuity" title=" visual acuity "> visual acuity </a> </p> <a href="https://publications.waset.org/abstracts/38454/prediction-of-changes-in-optical-quality-by-tissue-redness-after-pterygium-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38454.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">514</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">509</span> JENOSYS: Application of a Web-Based Online Energy Performance Reporting Tool for Government Buildings in Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norhayati%20Mat%20Wajid">Norhayati Mat Wajid</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Murad%20Zainal%20Abidin"> Abdul Murad Zainal Abidin</a>, <a href="https://publications.waset.org/abstracts/search?q=Faiz%20Fadzil"> Faiz Fadzil</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Yusof%20Aizad%20Mukhtar"> Mohd Yusof Aizad Mukhtar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the areas that present an opportunity to reduce the national carbon emission is the energy management of public buildings. To our present knowledge, there is no easy-to-use and centralized mechanism that enables the government to monitor the overall energy performance, as well as the carbon footprint, of Malaysia’s public buildings. Therefore, the Public Works Department Malaysia, or PWD, has developed a web-based energy performance reporting tool called JENOSYS (JKR Energy Online System), which incorporates a database of utility account numbers acquired from the utility service provider for analysis and reporting. For test case purposes, 23 buildings under PWD were selected and monitored for their monthly energy performance (in kWh), carbon emission reduction (in tCO₂eq) and utility cost (in MYR), against the baseline. This paper demonstrates the simplicity with which buildings without energy metering can be monitored centrally and the benefits that can be accrued by the government in terms of building energy disclosure and concludes with the recommendation of expanding the system to all the public buildings in Malaysia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy-efficient%20buildings" title="energy-efficient buildings">energy-efficient buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20management%20systems" title=" energy management systems"> energy management systems</a>, <a href="https://publications.waset.org/abstracts/search?q=government%20buildings" title=" government buildings"> government buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=JENOSYS" title=" JENOSYS"> JENOSYS</a> </p> <a href="https://publications.waset.org/abstracts/88725/jenosys-application-of-a-web-based-online-energy-performance-reporting-tool-for-government-buildings-in-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88725.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">174</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">508</span> Determination of Nanomolar Mercury (II) by Using Multi-Walled Carbon Nanotubes Modified Carbon Zinc/Aluminum Layered Double Hydroxide – 3 (4-Methoxyphenyl) Propionate Nanocomposite Paste Electrode</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Illyas%20Md%20Isa">Illyas Md Isa</a>, <a href="https://publications.waset.org/abstracts/search?q=Sharifah%20Norain%20Mohd%20Sharif"> Sharifah Norain Mohd Sharif</a>, <a href="https://publications.waset.org/abstracts/search?q=Norhayati%20Hashima"> Norhayati Hashima</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A mercury(II) sensor was developed by using multi-walled carbon nanotubes (MWCNTs) paste electrode modified with Zn/Al layered double hydroxide-3(4-methoxyphenyl)propionate nanocomposite (Zn/Al-HMPP).

This is due to lack of technical information that focus on the maintenance and care, issues, and challenges face by vertical greenery system under tropical climate conditions. This research aim to identify issues in implementation of vertical greenery system on existing government building in Malaysia. The methodology used are literature reviews (desktop study), observation on sites, and case studies. Initial findings indicates that design and maintenance issues of vertical greenery system are the main challenges faced mainly by designer, especially those who involved in decision-making process. It can be concluded that orientation, openings, maintenance, performance, longevity, structural load, access, wind resistance, design failure, system failure, and lack of maintenance foresight are the main factors that need to be considered. These factors should be holistically aligned towards the economic cost, effective time, and quality design in implementation of vertical greenery system on existing government building. A comprehensive implementation of vertical greenery system will lead to greater sustainable investment for government buildings and responsive action to climate change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=issues" title="issues">issues</a>, <a href="https://publications.waset.org/abstracts/search?q=government%20building" title=" government building"> government building</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance" title=" maintenance"> maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20greenery%20system" title=" vertical greenery system"> vertical greenery system</a> </p> <a href="https://publications.waset.org/abstracts/160626/issues-in-implementation-of-vertical-greenery-system-on-existing-government-building-in-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160626.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">84</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">505</span> A New Modification of Nonlinear Conjugate Gradient Coefficients with Global Convergence Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Alhawarat">Ahmad Alhawarat</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Mamat"> Mustafa Mamat</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Rivaie"> Mohd Rivaie</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Mohd"> Ismail Mohd</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Conjugate gradient method has been enormously used to solve large scale unconstrained optimization problems due to the number of iteration, memory, CPU time, and convergence property, in this paper we find a new class of nonlinear conjugate gradient coefficient with global convergence properties proved by exact line search.

The performance of any skin detection applications greatly relies on the two components: feature extraction and classification method. Skin color is the most vital information used for skin detection purpose. However, color feature alone sometimes could not handle images with having same color distribution with skin color. A color feature of pixel-based does not eliminate the skin-like color due to the intensity of skin and skin-like color fall under the same distribution. Hence, the statistical color analysis will be exploited such mean and standard deviation as an additional feature to increase the reliability of skin detector. In this paper, we studied the effectiveness of statistical color feature for human skin detection. Furthermore, the paper analyzed the integrated color and texture using eight classifiers with three color spaces of RGB, YCbCr, and HSV. The experimental results show that the integrating statistical feature using Random Forest classifier achieved a significant performance with an F1-score 0.969. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=color%20space" title="color space">color space</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title=" neural network"> neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20forest" title=" random forest"> random forest</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20detection" title=" skin detection"> skin detection</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20feature" title=" statistical feature"> statistical feature</a> </p> <a href="https://publications.waset.org/abstracts/43485/towards-integrating-statistical-color-features-for-human-skin-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43485.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">462</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">502</span> Characterizing of CuO Incorporated CMOS Dielectric for Fast Switching System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nissar%20Mohammad%20Karim">Nissar Mohammad Karim</a>, <a href="https://publications.waset.org/abstracts/search?q=Norhayati%20Soin"> Norhayati Soin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To ensure fast switching in high-K incorporated Complementary Metal Oxide Semiconductor (CMOS) transistors, the results on the basis of d (NBTI) by incorporating SiO2 dielectric with aged samples of CuO sol-gels have been reported.

People using this alternative digital money to do a transaction in many ways (e.g. Used for online shopping, wealth management, and fundraising). However, this digital asset also widely used in criminal activities since its use decentralized control as opposed to centralized electronic money and central banking systems and this makes a user, who used this currency invisible. The high-value exchange of these digital currencies also has been a target to criminal activities. The cryptocurrency crimes have become a challenge for the law enforcement to analyze and to proof the evidence as criminal devices. In this paper, our focus is more on bitcoin cryptocurrency and the possible artifacts that can be obtained from the different type of digital wallet, which is software and browser-based application. The process memory and physical hard disk are examined with the aims of identifying and recovering potential digital evidence. The stage of data acquisition divided by three states which are the initial creation of the wallet, transaction that consists transfer and receiving a coin and the last state is after the wallet is being deleted. Findings from this study suggest that both data from software and browser type of wallet process memory is a valuable source of evidence, and many of the artifacts found in process memory are also available from the application and wallet files on the client computer storage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptocurrency" title="cryptocurrency">cryptocurrency</a>, <a href="https://publications.waset.org/abstracts/search?q=bitcoin" title=" bitcoin"> bitcoin</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20wallet" title=" digital wallet"> digital wallet</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20forensics" title=" digital forensics"> digital forensics</a> </p> <a href="https://publications.waset.org/abstracts/94467/cryptocurrency-forensics-analysis-on-bitcoin-e-wallet-from-computer-source-evidence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94467.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">340</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">500</span> Cytochrome B Marker Reveals Three Distinct Genetic Lineages of the Oriental Latrine Fly Chrysomya megacephala (Diptera: Calliphoridae) in Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajagopal%20Kavitha">Rajagopal Kavitha</a>, <a href="https://publications.waset.org/abstracts/search?q=Van%20Lun%20Low"> Van Lun Low</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Sofian-Azirun"> Mohd Sofian-Azirun</a>, <a href="https://publications.waset.org/abstracts/search?q=Chee%20Dhang%20Chen"> Chee Dhang Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Yusof%20Farida%20Zuraina"> Mohd Yusof Farida Zuraina</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Salleh%20Ahmad%20Firdaus"> Mohd Salleh Ahmad Firdaus</a>, <a href="https://publications.waset.org/abstracts/search?q=Navaratnam%20Shanti"> Navaratnam Shanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Haiyee%20Zaibunnisa"> Abdul Haiyee Zaibunnisa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigated the hidden genetic lineages in the oriental latrine fly Chrysomya megacephala (Fabricius) across four states (i.e., Johore, Pahang, Perak and Selangor) and a federal territory (i.e., Kuala Lumpur) in Malaysia using Cytochrome b (Cyt b) genetic marker. The Cyt b phylogenetic tree and haplotype network revealed three distinct genetic lineages of Ch. megacephala. Lineage A, the basal clade was restricted to flies that originated from Kuala Lumpur and Selangor, while Lineages B and C, comprised of flies from all studied populations. An overlap of the three genetically divergent groups of Ch. megacephala was observed. However, the flies from both Kuala Lumpur and Selangor populations consisted of three different lineages, indicating that they are genetically diverse compared to those from Pahang, Perak and Johore. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forensic%20entomology" title="forensic entomology">forensic entomology</a>, <a href="https://publications.waset.org/abstracts/search?q=calliphoridae" title=" calliphoridae"> calliphoridae</a>, <a href="https://publications.waset.org/abstracts/search?q=mitochondrial%20DNA" title=" mitochondrial DNA"> mitochondrial DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=cryptic%20lineage" title=" cryptic lineage"> cryptic lineage</a> </p> <a href="https://publications.waset.org/abstracts/47473/cytochrome-b-marker-reveals-three-distinct-genetic-lineages-of-the-oriental-latrine-fly-chrysomya-megacephala-diptera-calliphoridae-in-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47473.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">512</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">499</span> Changes in Religious Belief after Flood Disasters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sapora%20Sipon">Sapora Sipon</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Fo%E2%80%99ad%20Sakdan"> Mohd Fo’ad Sakdan</a>, <a href="https://publications.waset.org/abstracts/search?q=Che%20Su%20Mustaffa"> Che Su Mustaffa</a>, <a href="https://publications.waset.org/abstracts/search?q=Najib%20Ahmad%20Marzuki"> Najib Ahmad Marzuki</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Sukeri%20Khalid"> Mohamad Sukeri Khalid</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Taib%20Ariffin"> Mohd Taib Ariffin</a>, <a href="https://publications.waset.org/abstracts/search?q=Husni%20Mohd%20Radzi"> Husni Mohd Radzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Salhah%20Abdullah"> Salhah Abdullah </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flood disasters occur throughout the world including Malaysia.

The use of appropriate features plays an important role in determining accuracy of signature verification; therefore, this paper presents a feature based on the geometrical concept. To achieve the aim, triangle attributes are exploited to design a new feature since the triangle possesses orientation, angle and transformation that would improve accuracy. The proposed feature uses triangulation geometric set comprising of sides, angles and perimeter of a triangle which is derived from the center of gravity of a signature image. For classification purpose, Euclidean classifier along with Voting-based classifier is used to verify the tendency of forgery signature. This classification process is experimented using triangular geometric feature and selected global features. Based on an experiment that was validated using Grupo de Senales 960 (GPDS-960) signature database, the proposed triangular geometric feature achieves a lower Average Error Rates (AER) value with a percentage of 34% as compared to 43% of the selected global feature. As a conclusion, the proposed triangular geometric feature proves to be a more reliable feature for accurate signature verification. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biometrics" title="biometrics">biometrics</a>, <a href="https://publications.waset.org/abstracts/search?q=euclidean%20classifier" title=" euclidean classifier"> euclidean classifier</a>, <a href="https://publications.waset.org/abstracts/search?q=features%20extraction" title=" features extraction"> features extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=offline%20signature%20verification" title=" offline signature verification"> offline signature verification</a>, <a href="https://publications.waset.org/abstracts/search?q=voting-based%20classifier" title=" voting-based classifier"> voting-based classifier</a> </p> <a href="https://publications.waset.org/abstracts/45300/triangular-geometric-feature-for-offline-signature-verification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45300.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">378</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">497</span> Studies on Induction of Cytotoxicity Through Apoptosis In Ovarian Cancer Cell Line (CAOV-3) by Chloroform Extract of Artocarpus Kemando Miq</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noor%20Shafifiyaz%20Mohd%20Yazid">Noor Shafifiyaz Mohd Yazid</a>, <a href="https://publications.waset.org/abstracts/search?q=Najihah%20Mohd%20Hashim"> Najihah Mohd Hashim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hapipah%20Mohd%20Ali"> Hapipah Mohd Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Syam%20Mohan"> Syam Mohan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosea%20Go"> Rosea Go</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Artocarpus kemando is a plant species from Moraceae family. This plant is used as household utensil by the local and the fruits are edible. The plants’ bark was used for the extraction process and yielded the chloroform crude extract which was used to screen for anticancer potential. The cytotoxic effect of the extract on CAOV-3 and WRL 68 cell lines were determined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide or MTT assays. Qualitative AO/PI assay was performed to confirm the apoptosis and necrosis process. Meanwhile, the measurement of cell loss, nuclear morphology, DNA content, cell membrane permeability, mitochondrial membrane potential changes and cytochrome c release from mitochondria were detected through cytotoxicity 3 assay. In MTT assay, A. kemando inhibited 50% growth of CAOV-3 cells at 27.9 ± 0:03, 20.1± 0:03, 18.21± 0:04 µg/mL after 24, 48 and 72 hour, respectively. The morphology changes can be seen on CAOV-3 with a production of cell membrane blebbing, cromatin condensation and apoptotic bodies. Evaluation of cytotoxicity 3 on CAOV-3 cells after treated with extract resulting loss of mitochondrial membrane potential and release of cytochrome c from mitochondria. The results demonstrated A. kemando has potentially anticancer agent, particularly on human ovarian cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anticancer" title="anticancer">anticancer</a>, <a href="https://publications.waset.org/abstracts/search?q=Artocarpus%20kemando" title=" Artocarpus kemando"> Artocarpus kemando</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=cytotoxicity" title=" cytotoxicity"> cytotoxicity</a> </p> <a href="https://publications.waset.org/abstracts/13699/studies-on-induction-of-cytotoxicity-through-apoptosis-in-ovarian-cancer-cell-line-caov-3-by-chloroform-extract-of-artocarpus-kemando-miq" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13699.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">551</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">496</span> The Effect of Second Victim-Related Distress on Work-Related Outcomes in Tertiary Care, Kelantan, Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Zulfahmi%20Mohd%20Kamaruzaman">Ahmad Zulfahmi Mohd Kamaruzaman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Ismail%20Ibrahim"> Mohd Ismail Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ariffin%20Marzuki%20Mokhtar"> Ariffin Marzuki Mokhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Maizun%20Mohd%20Zain"> Maizun Mohd Zain</a>, <a href="https://publications.waset.org/abstracts/search?q=Saiful%20Nazri%20Satiman"> Saiful Nazri Satiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Najib%20Majdi%20Yaacob"> Mohd Najib Majdi Yaacob</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Aftermath any patient safety incidents, the involved healthcare providers possibly sustained second victim-related distress (second victim distress and reduced their professional efficacy), with subsequent negative work-related outcomes or vice versa cultivating resilience. This study aimed to investigate the factors affecting negative work-related outcomes and resilience, with the triad of support; colleague, supervisor, and institutional support as the hypothetical mediators. Methods: This was a cross sectional study recruiting a total of 733 healthcare providers from three tertiary care in Kelantan, Malaysia. Three steps of hierarchical linear regression were developed for each outcome; negative work-related outcomes and resilience. Then, four multiple mediator models of support triad were analyzed. Results: Second victim distress, professional efficacy, and the support triad contributed significantly for each regression model. In the pathway of professional efficacy on each negative work-related outcomes and resilience, colleague support partially mediated the relationship. As for second victim distress on negative work related outcomes, colleague and supervisor support were the partial mediator, and on resilience; all support triad also produced a similar effect. Conclusion: Second victim distress, professional efficacy, and the support triad influenced the relationship with the negative work-related outcomes and resilience. Support triad as the mediators ameliorated the effect in between and explained the urgency of having good support for recovery post encountering patient safety incidents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=second%20victims" title="second victims">second victims</a>, <a href="https://publications.waset.org/abstracts/search?q=patient%20safety%20incidents" title=" patient safety incidents"> patient safety incidents</a>, <a href="https://publications.waset.org/abstracts/search?q=hierarchical%20linear%20regression" title=" hierarchical linear regression"> hierarchical linear regression</a>, <a href="https://publications.waset.org/abstracts/search?q=mediation" title=" mediation"> mediation</a>, <a href="https://publications.waset.org/abstracts/search?q=support" title=" support"> support</a> </p> <a href="https://publications.waset.org/abstracts/150191/the-effect-of-second-victim-related-distress-on-work-related-outcomes-in-tertiary-care-kelantan-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150191.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">108</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">495</span> Low Back Pain among Nurses in Penang Public Hospitals: A Study on Prevalence and Factors Associated</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Izani%20Uzair%20Zubair">Izani Uzair Zubair</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Ismail%20Ibrahim"> Mohd Ismail Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Nazri%20Shafei"> Mohd Nazri Shafei</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Merican%20Omar%20Naina%20Merican"> Hassan Merican Omar Naina Merican</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Sabri%20Othman"> Mohamad Sabri Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Izmi%20Ahmad%20Ibrahim"> Mohd Izmi Ahmad Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasilah%20Ramli"> Rasilah Ramli</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajpal%20Singh%20Karam%20Singh"> Rajpal Singh Karam Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nurses experience a higher prevalence of low back pain (LBP) and musculoskeletal complaints as compared to other hospital workers. Due to no proper policy related to LBP, the job has exposed them to the problem. Thus, the current study aims to look at the intensity of the problem and factors associated with development of LBP. Method and Tools: A cross sectional study was carried out among 1292 nurses from six public hospitals in Penang. They were randomly selected and those who were pregnant and have been diagnosed to have LBP were excluded. A Malay validated BACK Questionnaire was used. The associated factors were determined by using multiple logistic regression from SPSS version 20.0. Result: Most of the respondents were at mean age 30 years old and had mean working experience 86 months. The prevalence of LBP was identified as 76% (95% CI 74, 82). Factors that were associated with LBP among nurses include lifting a heavy object (OR2.626 (95% CI 1.978, 3.486) p =0.001 and the estimation weight of the lifted object (OR1.443 (95% CI 1.056, 1.970) p =0.021. Conclusion: Nurses who practice lifting heavy object and weight of the object lifted give a significant contribution to the development of LBP. The prevalence of the problem is significantly high. Thus, a proper no weight lifting policy should be considered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20back%20pain" title="low back pain">low back pain</a>, <a href="https://publications.waset.org/abstracts/search?q=nurses" title=" nurses"> nurses</a>, <a href="https://publications.waset.org/abstracts/search?q=Penang%20public%20hospital" title=" Penang public hospital"> Penang public hospital</a>, <a href="https://publications.waset.org/abstracts/search?q=Penang" title=" Penang"> Penang</a> </p> <a href="https://publications.waset.org/abstracts/64098/low-back-pain-among-nurses-in-penang-public-hospitals-a-study-on-prevalence-and-factors-associated" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64098.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">487</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">494</span> A Review on Light Shafts Rendering for Indoor Scenes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hatam%20H.%20Ali">Hatam H.

The existence of PD activities is an early indication of insulation weakness hence early detection of PD activities can be determined and provides an initial prediction on the condition of the cable. To effectively manage the results of PD Mapping test, it is important to have acceptable criteria to facilitate prioritization of mitigation action. Tenaga Nasional Berhad (TNB) through Distribution Network (DN) division have developed PD severity model name Severity Index (SI) for offline PD mapping test since 2007 based on onsite test experience. However, this severity index recommendation action had never been revised since its establishment. At presence, PD measurements data have been extensively increased, hence the severity level indication and the effectiveness of the recommendation actions can be analyzed and verified again. Based on the new revision, the recommended action to be taken will be able to reflect the actual defect condition. Hence, will be accurately prioritizing preventive action plan and minimizing maintenance expenditure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=partial%20discharge" title="partial discharge">partial discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=severity%20index" title=" severity index"> severity index</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnostic%20testing" title=" diagnostic testing"> diagnostic testing</a>, <a href="https://publications.waset.org/abstracts/search?q=medium%20voltage" title=" medium voltage"> medium voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20cable" title=" power cable"> power cable</a> </p> <a href="https://publications.waset.org/abstracts/128295/severity-index-level-in-effectively-managing-medium-voltage-underground-power-cable" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128295.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">186</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">492</span> Microwave-Assisted Synthesis of Silver Nanoparticles from Dioscorea Deltoidea Callus Extract and Evaluation of Its Antimicrobial Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mujeeb%20Mohd">Mujeeb Mohd</a>, <a href="https://publications.waset.org/abstracts/search?q=Aqil%20Mohd"> Aqil Mohd</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20K.%20Najmi"> A.

D. deltoidea commonly known as yam and is an extensively used medicinal plant in the indigenous system of medicine. It has been reported to contain dioscine a steroidal glycoside in higher concentration. In the present investigation, silver nanoparticles (AgNPs) have been synthesized by a simple, efficient, environmentally benevolent and economic microwave-assisted method. Callus culture of D. deltoidea was developed and maintained on Murashige and skooge basal medium supplemented with different combination and concentration of plant growth regulators. Aqueous extract of callus culture was used as the reducing and stabilizing agent. The synthesized nanoparticles have been characterized by UV–Vis spectroscopy, Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and X-ray diffraction (XRD analysis. The presence of a characteristic surface plasmon resonance (SPR) absorption band at 430 nm in UV–Vis reveals the reduction of silver metal ions into silver nanoparticles. Whereas FTIR analysis was performed to probe the possible functional group involved in the synthesis of AgNPs. Further extract and AgNPs were evaluated for antimicrobial activity against different pathogenic microorganisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title="antimicrobial">antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=Dioscorea%20deltoidea" title=" Dioscorea deltoidea"> Dioscorea deltoidea</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave" title=" microwave"> microwave</a>, <a href="https://publications.waset.org/abstracts/search?q=silver" title=" silver"> silver</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title=" nanoparticles"> nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/64630/microwave-assisted-synthesis-of-silver-nanoparticles-from-dioscorea-deltoidea-callus-extract-and-evaluation-of-its-antimicrobial-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64630.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">268</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">491</span> Understanding Success Factors of an Information Security Management System Plan Phase Self-Implementation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nurazean%20Maarop">Nurazean Maarop</a>, <a href="https://publications.waset.org/abstracts/search?q=Noorjan%20Mohd%20Mustapha"> Noorjan Mohd Mustapha</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasimah%20Yusoff"> Rasimah Yusoff</a>, <a href="https://publications.waset.org/abstracts/search?q=Roslina%20Ibrahim"> Roslina Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Norziha%20Megat%20Mohd%20Zainuddin"> Norziha Megat Mohd Zainuddin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The goal of this study is to identify success factors that could influence the ISMS self-implementation in government sector from qualitative perspective.

This study compared CC measurements conducted with two optical devices in phakic eyes. Methods: Sixty phakic eyes of 30 patients were enrolled in this study. CC was measured three times with the optical biometer and topography-keratometer Tomey AO-2000 (Tomey Corporation, Nagoya, Japan), then with the standard partial optical coherence interferometry (PCI) IOL Master (Carl Zeiss Meditec, Dublin, CA) and data were statistically analysed. Results: The measurements resulted in a mean CC of 43.86 ± 1.57 D with Tomey AO-2000 and 43.84 ± 1.55 D with IOL Master. Distribution of data is normal, and no significance difference in CC values was detected (P = 0.952) between the two devices. Correlation between CC measurements was highly significant (r = 0. 99; P < 0.0001). The mean difference of CC values between devices was 0.017 D and 95% limit of agreement was -0.088 to 0.12. Duration taken for measurements with the standard biometer IOL Master was longer (55.17 ± 2.24 seconds) than with Tomey AO-2000 (39.88 ± 2.38 seconds) in automatic mode. Duration of manual measurement with Tomey AO-2000 in manual mode was the shortest (28.57 ± 2.71 seconds). Conclusion: In phakic eyes, CC measured with Tomey AO-2000 and IOL Master showed similar values, and high correlation was observed between these two devices. This shows that both devices can be used interchangeably. Tomey AO-2000 is better in terms of faster to operate and has its own topography systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corneal%20topography" title="corneal topography">corneal topography</a>, <a href="https://publications.waset.org/abstracts/search?q=corneal%20curvature" title=" corneal curvature"> corneal curvature</a>, <a href="https://publications.waset.org/abstracts/search?q=IOL%20Master" title=" IOL Master"> IOL Master</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomey%20AO2000" title=" Tomey AO2000 "> Tomey AO2000 </a> </p> <a href="https://publications.waset.org/abstracts/38452/comparison-of-corneal-curvature-measurements-conducted-with-tomey-ao-2000-and-the-current-standard-biometer-iol-master" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38452.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">387</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">488</span> Level Set and Morphological Operation Techniques in Application of Dental Image Segmentation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdolvahab%20Ehsani%20Rad">Abdolvahab Ehsani Rad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Shafry%20Mohd%20Rahim"> Mohd Shafry Mohd Rahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Norouzi"> Alireza Norouzi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Medical image analysis is one of the great effects of computer image processing.

Furthermore, unlike synthetic fiber, a diameter and cross-sectional area of natural fiber has a large variation along and between the fibers. This study aims to determine the main and interaction effects of alkali treatment conditions that influence kenaf bast fiber mean cross-sectional area. Three alkali treatment conditions at two different levels were selected. The conditions setting were alkali concentrations at two and ten w/v %; fiber immersed temperature at room temperature and 1000C; and fiber immersed duration for 30 and 480 minute. Untreated kenaf fiber was used as a control unit. Kenaf bast fiber bundle mounting tab was prepared according to ASTM C1557-03. The cross-sectional area was measured using a Leica video analyzer. The study result showed that kenaf fiber bundle mean cross-sectional area was reduced 6.77% to 29.88% after alkali treatment. From the analysis of variance, it shows that the interaction of alkali concentration and immersed time has a higher magnitude at 0.1619 compared to alkali concentration and immersed temperature interaction that was 0.0896. For the main effect, alkali concentration factor contributes to the higher magnitude at 0.1372 which indicated the decrease pattern of variability when the level changed from lower to the higher level. Then, it was followed by immersed temperature at 0.1261 and immersed time at 0.0696 magnitudes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=natural%20fiber" title="natural fiber">natural fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=kenaf%20bast%20fiber%20bundles" title=" kenaf bast fiber bundles"> kenaf bast fiber bundles</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=cross-sectional%20area" title=" cross-sectional area"> cross-sectional area</a> </p> <a href="https://publications.waset.org/abstracts/2033/determination-of-alkali-treatment-conditions-effects-that-influence-the-variability-of-kenaf-fiber-mean-cross-sectional-area" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2033.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">426</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">486</span> The Development of GPS Buoy for Ocean Surface Monitoring: Initial Results</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anuar%20Mohd%20Salleh">Anuar Mohd Salleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Effendi%20Daud"> Mohd Effendi Daud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents a kinematic positioning approach which is use the GPS buoy for precise ocean surface monitoring. A GPS buoy data from two experiments have been processed using a precise, medium-range differential kinematic technique. In each case the data were collected for more than 24 hours at nearby coastal site at a high rate (1 Hz), along with measurements from neighboring tidal stations, to verify the estimated sea surface heights. Kinematic coordinates of GPS buoy were estimated using the epoch-wise pre-elimination and the backward substitution algorithm. Test results show the centimeter level accuracy in sea surface height determination can be successfully achieved using proposed technique. The centimeter level agreement between two methods also suggests the possibility of using this inexpensive and more flexible GPS buoy equipment to enhance (or even replace) the current use of tidal gauge stations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=global%20positioning%20system" title="global positioning system">global positioning system</a>, <a href="https://publications.waset.org/abstracts/search?q=kinematic%20GPS" title=" kinematic GPS"> kinematic GPS</a>, <a href="https://publications.waset.org/abstracts/search?q=sea%20surface%20height" title=" sea surface height"> sea surface height</a>, <a href="https://publications.waset.org/abstracts/search?q=GPS%20buoy" title=" GPS buoy"> GPS buoy</a>, <a href="https://publications.waset.org/abstracts/search?q=tide%20gauge" title=" tide gauge"> tide gauge</a> </p> <a href="https://publications.waset.org/abstracts/23300/the-development-of-gps-buoy-for-ocean-surface-monitoring-initial-results" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23300.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">544</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">485</span> Square Wave Anodic Stripping Voltammetry of Copper (II) at the Tetracarbonylmolybdenum(0) MWCNT Paste Electrode</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Illyas%20Isa">Illyas Isa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Idris%20Saidin"> Mohamad Idris Saidin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustaffa%20Ahmad"> Mustaffa Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Norhayati%20Hashim"> Norhayati Hashim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A highly selective and sensitive electrode for determination of trace amounts of Cu (II) using square wave anodic stripping voltammetry (SWASV) was proposed. The electrode was made of the paste of multiwall carbon nanotubes (MWCNT) and 2,6–diacetylpyridine-di-(1R)–(-)–fenchone diazine tetracarbonylmolybdenum(0) at 100:5 (w/w). Under optimal conditions the electrode showed a linear relationship with concentration in the range of 1.0 × 10–10 to 1.0 × 10– 6 M Cu (II) and limit of detection 8.0 × 10–11 M Cu (II). The relative standard deviation (n = 5) of response to 1.0 × 10–6 M Cu(II) was 0.036. The interferences of cations such as Ni(II), Mg(II), Cd(II), Co(II), Hg(II), and Zn(II) (in 10 and 100-folds concentration) are negligible except from Pb (II). Electrochemical impedance spectroscopy (EIS) showed that the charge transfer at the electrode-solution interface was favorable. Result of analysis of Cu(II) in several water samples agreed well with those obtained by inductively coupled plasma-optical emission spectrometry (ICP-OES). The proposed electrode was then recommended as an alternative to spectroscopic technique in analyzing Cu (II). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemically%20modified%20electrode" title="chemically modified electrode">chemically modified electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=Cu%28II%29" title=" Cu(II)"> Cu(II)</a>, <a href="https://publications.waset.org/abstracts/search?q=Square%20wave%20anodic%20stripping%20voltammetry" title=" Square wave anodic stripping voltammetry"> Square wave anodic stripping voltammetry</a>, <a href="https://publications.waset.org/abstracts/search?q=tetracarbonylmolybdenum%280%29" title=" tetracarbonylmolybdenum(0)"> tetracarbonylmolybdenum(0)</a> </p> <a href="https://publications.waset.org/abstracts/45191/square-wave-anodic-stripping-voltammetry-of-copper-ii-at-the-tetracarbonylmolybdenum0-mwcnt-paste-electrode" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45191.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">262</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">484</span> Characteristics of the Poor in Malaysia: Evidence from E-Kasih Database an Explanatory Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zunaidah%20Ab%20Hasan">Zunaidah Ab Hasan</a>, <a href="https://publications.waset.org/abstracts/search?q=Azhana%20Othman"> Azhana Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Abd%20Halim%20Mohd%20Noor"> Abd Halim Mohd Noor</a>, <a href="https://publications.waset.org/abstracts/search?q=Nor%20Shahrina%20Mohd%20Rafien"> Nor Shahrina Mohd Rafien</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study highlights some of the factors of the poor in Malaysia by household and individual level. The discussion covers the demographic, economic and social aspects. The data is derived from the National Databank of Poverty Malaysia (eKasih) for the year of 2013. The explanatory analysis is used to analyse factor of poverty in Malaysia specifically in Malacca. The evidence confirms that male are prone to be poor. For the ethnic, majority of the poor are Malays. The number of dependency and unskilled head of household also contributes to the factors to be poor. Despite that health and physical condition condition does not affect the household head is likely to be poor. Outcome of this study hope to provide guideline that would beneficial to various stakeholders such as zakat institutions, policy makers, welfare department and other agencies related. This will lead to better standard of living as envisioned in the fourth National Key Result Areas (NKRAs). <p class="card-text"><strong>Keywords:</strong> <a
