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">1026</span> A Preliminary Investigation on Factors that Influence Malaysian Road User’s Close Following Behaviour</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siti%20Hikmah%20Musthar">Siti Hikmah Musthar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Saifizul"> Ahmad Saifizul</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Rehan%20Karim"> Mohamed Rehan Karim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamilah%20Mohamad"> Jamilah Mohamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Farah%20Fazlinda%20Mohamad"> Farah Fazlinda Mohamad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to look at the situation of close following behaviour from the introductory phase before conducting a profound investigation and discussion on this subject. Close following behaviour is known as behaviour during when drivers follow front vehicle with headways lower than two-second. As such, the study of close-following is important due to the degree of negative consequences this behaviour can cause commonly identified as rear-end collision especially when road safety is concerned. This paper presents a preliminary results of close-following behaviour among selected respondents (n=515) in Peninsular Malaysia at selected highways and federal roads. Respondents were interviewed with survey questions tending to examine their actual driving behaviour related to close-following and their perception towards the subject of close following. Selected findings (four selected questions) are discussed in this paper of which identified as essential for deliberation (as opposed to other questions in the survey questionnaire) as far as a preliminary discussion is concerned. Through the statistical test of one-way ANOVA, study found that gender of drivers is not significant to influence drivers to close follow but instead, type of vehicle the respondent drives had more significant to influence drivers to have tendency to perform close following behaviour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=close-following" title="close-following">close-following</a>, <a href="https://publications.waset.org/abstracts/search?q=driver%20behaviour" title=" driver behaviour"> driver behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=rear-end%20crash" title=" rear-end crash"> rear-end crash</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20safety" title=" road safety "> road safety </a> </p> <a href="https://publications.waset.org/abstracts/35228/a-preliminary-investigation-on-factors-that-influence-malaysian-road-users-close-following-behaviour" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35228.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">420</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1025</span> Jalal-Ale-Ahmad and ‘Critical Consciousness’: A Comparative Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zohreh%20Ramin">Zohreh Ramin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the most important contributions that Edward Said has had in the realm of critical theory is his insistence on the worldliness of the text and the critic. By this, Said meant that the critic and the text must be considered in their ‘material’ contexts. Foregrounding the substantial role of a critic as embodying what he refers to as ‘critical consciousness’, a true critic, Said maintains, is one who can stand between the ‘dominant culture’ and ‘the totalizing forms of critical systems.’ Considered as one of Iran’s major contemporary intellectuals, Jalal Ale Ahmad is responsible for introducing the idea of ‘Westoxication’ in Iran, constructing a social paradigm of the necessity to return to tradition in contemporary Iran. The present paper intends to study Al-Ahmad’s definition of the orient versus the occident, his criticism of the ‘machination’ of contemporary Iranian society, and his solution to the problem of ‘Westoxication’. The objective of this study is to see whether Ale Ahmad can be considered as embodying the spirit of ‘critical consciousness’ as described by Said as the necessary tool in the hands of an intellectual who is simultaneously attached filitavely to his culture but can detach himself affilitavely through employing critical consciousness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Westoxication" title="Westoxication">Westoxication</a>, <a href="https://publications.waset.org/abstracts/search?q=filiative" title=" filiative"> filiative</a>, <a href="https://publications.waset.org/abstracts/search?q=affiliative" title=" affiliative"> affiliative</a>, <a href="https://publications.waset.org/abstracts/search?q=machination" title=" machination"> machination</a> </p> <a href="https://publications.waset.org/abstracts/137668/jalal-ale-ahmad-and-critical-consciousness-a-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137668.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">184</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1024</span> A Preliminary Investigation on Factors that Influence Road Users Speeding Behaviors in Selected Roads of Peninsular Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farah%20Fazlinda%20Binti%20Mohamad">Farah Fazlinda Binti Mohamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Hikmah%20Binti%20Musthar"> Siti Hikmah Binti Musthar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Saifizul%20Bin%20Abdullah"> Ahmad Saifizul Bin Abdullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamilah%20Mohamad"> Jamilah Mohamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Rehan%20Karim"> Mohamed Rehan Karim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Road safety is intolerable issue. It affects and impinges on everyone's life as the roads shared by everyone. The most vulnerable victims were the road users who cater the roads every day. It is an appalling when World Health Organization reported that Malaysian road users were ranked worst in Asian countries with 23 deaths for every 100,000 of population over the span of 12 years (World Health Organization, 2009). From this report, it is found that speeding has contributed to 60% of all accidents in the country. Therefore, this study aims to elucidate on speeding matter that occur among road users in selected roads of Peninsular Malaysia. This study on the other hand, provides an insight understanding on the factors affecting behaviour of road users to speeding in selected roads of Peninsular Malaysia. To answer the study aims, 500 sets of questionnaires were distributed among 500 respondents in selected roads of Peninsular Malaysia to obtain their opinions on the matter. The respondents were from different demographics backgrounds to have fair explanation on the issue. The answers have been analysed using descriptive analysis. The results indicated psychological factors of road users appeared to be prominent in explaining road users’ behaviour to speeding. Male road users were also found dominant in speeding compared to female. Thus, this has increased their vulnerability to road injuries and deaths. These findings are very useful in order for us to improve our driving behaviour. Relevant authorities should also revise the existing countermeasures as well as designing the new countermeasures for the road users. It is nevertheless important to comprehend this speeding issue and factors associating it. This matter should be taken seriously and responsibly by each road users as road safety is a responsible of all. <p class="card-text"><strong>Keywords:</strong> <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=speeding" title=" speeding"> speeding</a>, <a href="https://publications.waset.org/abstracts/search?q=countermeasures" title=" countermeasures"> countermeasures</a>, <a href="https://publications.waset.org/abstracts/search?q=accidents" title=" accidents"> accidents</a> </p> <a href="https://publications.waset.org/abstracts/29865/a-preliminary-investigation-on-factors-that-influence-road-users-speeding-behaviors-in-selected-roads-of-peninsular-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29865.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">1023</span> A Preliminary Investigation on Factors That Influence Road Users' Speeding Behaviour on Selected Roads in Peninsular Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farah%20Fazlinda%20Binti%20Mohamad">Farah Fazlinda Binti Mohamad</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=Mohamed%20Rehan%20Karim"> Mohamed Rehan Karim </a>, <a href="https://publications.waset.org/abstracts/search?q=Jamilah%20Mohamad"> Jamilah Mohamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Hikmah%20Musthar"> Siti Hikmah Musthar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Road safety is an important issue in Malaysia. It become important as it is discussed widely throughout printed and electronic media. Most of the news portrays on road accident and fatalities have increased the concern of everyone. This issue affects everyone's life as everyone shares the roads. The most vulnerable victims are the road user who uses the roads every day. It is appalling when World Health Organization (WHO) reported that in every 100,000 of population in Malaysia, 23 fatalities recorded due to road accident alone. This figure is quite alarming and requires serious attention. Furthermore, research by Malaysian Institute of Road Safety Research concluded that that speeding has contributed to 60% of all road accident in the country.

Based on Malaysian Institute of Road Safety Research (Miros) latest research ‘Predicting Malaysian Road Fatalities for year 2020; it is predicted that road fatalities in Malaysia for 2015 is 8,780 and 10,716 for the year 2020 which 30 percent of fatalities were caused by accidents involving commercial vehicles. Government, related agencies and NGOs have continuously and persistently work to reduce the statistics through enforcement, educating the public, training to drivers, road safety campaigns, advertisements etc. However, the trend of casualties does not show encouraging pattern but instead, steadily growing. Thus, this comparative study reviews the literature pertaining on method of measurement used to evaluate commercial drivers competency. In several studies driving competency has been assessed with different assessment based on the license procedures and requirements according to the country regulation. The assessment criteria that has been establish for commercial drivers generally focus on driving tasks and assessment e.g. theory test, medical test and road assessment rather than driving competency test or physical test. Realizing the importance of specific assessment test for drivers competency this comparative study reviews the most discussed literature related to competency assessment method to identify competency of the drivers include (1. judgement and reaction, 2. skill of drivers, 3. experiences and fatigue). The concluding analysis of this paper is a comparative table for assessment methodology to access driver’s competency. A comparative study is a further discussion reviewing past literature to provide an overview on existing assessment test and potential subject matters that can be identified for further studies to increase awareness of the drivers, passengers as well as the authorities about the importance of competent drivers in order to improve safety in commercial vehicles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=commercial%20vehicles" title="commercial vehicles">commercial vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=driver%E2%80%99s%20competency" title=" driver’s competency"> driver’s competency</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20assessment" title=" specific assessment"> specific assessment</a> </p> <a href="https://publications.waset.org/abstracts/29855/a-comparative-study-of-specific-assessment-criteria-related-to-commercial-vehicle-drivers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29855.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">443</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1021</span> Analysis of Wheel Lock up Effects on Skidding Distance for Heavy Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdieh%20Zamzamzadeh">Mahdieh Zamzamzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Abdullah%20Saifizul"> Ahmad Abdullah Saifizul</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahizar%20Ramli"> Rahizar Ramli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The road accidents involving heavy vehicles have been showing worrying trends and, year after year, have increased the concern and awareness levels on safety of roads and transportations especially in developing countries like Malaysia. Statistics of road crashes continue to show that there are many contributing factors on the capability of a heavy vehicle to stop on safe distance and ultimately prevent traffic crashes. However, changes in the road condition due to weather variations and the vehicle dynamic specifications such as loading conditions and speed are the main risk factors because they will affect a heavy vehicle’s braking performance due to losing control and not being able to stop the vehicle, and in many cases will cause wheel lock up and accordingly skidding. Predicting heavy vehicle skidding distance is crucial for accident reconstruction and roadside safety engineers. Despite this, formal tools to study heavy vehicle skidding distance before stopping completely are totally limited, and most researchers have only considered braking distance in their studies. As a possible new tool, this work presents the iterative use of vehicle dynamic simulations to study heavy vehicle-roadway interaction in order to predict wheel lock up effects on skidding distance and safety. This research addresses the influence of the vehicle and road conditions on skidding distance after wheel lock up and presents a precise analysis of skidding phenomenon. The vehicle speed, vehicle loading condition and road friction parameters were all varied in a simulation-based analysis. In order to simulate the wheel lock up situation, a heavy vehicle model was constructed and simulated using multibody vehicle dynamics simulation software, and careful analysis was made on the conditions which caused the skidding distance to increase or decrease through a method using to predict skidding distance as part of braking distance. By applying many simulations, the results were quite revealing relation between the heavy vehicles loading condition, various sets of speed and road coefficient of friction and their interaction effect on the skidding distance. A number of results are presented which illustrate how the heavy vehicle overloading can seriously affect the skidding distance. Moreover, the results of simulation give the skid mark length, which is a necessary input data during accident reconstruction involving emergency braking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accident%20reconstruction" title="accident reconstruction">accident reconstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=Braking" title=" Braking"> Braking</a>, <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=skidding%20distance" title=" skidding distance"> skidding distance</a>, <a href="https://publications.waset.org/abstracts/search?q=skid%20mark" title=" skid mark"> skid mark</a>, <a href="https://publications.waset.org/abstracts/search?q=wheel%20lock%20up" title=" wheel lock up"> wheel lock up</a> </p> <a href="https://publications.waset.org/abstracts/29868/analysis-of-wheel-lock-up-effects-on-skidding-distance-for-heavy-vehicles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29868.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">499</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">1020</span> A Study of the Formation, Existence and Stability of Localised Pulses in PDE</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayaz%20Ahmad">Ayaz Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> TOPIC: A study of the formation ,existness and stability of localised pulses in pde Ayaz Ahmad ,NITP, Abstract:In this paper we try to govern the evolution deterministic variable over space and time .We analysis the behaviour of the model which allows us to predict and understand the possible behaviour of the physical system .Bifurcation theory provides a basis to systematically investigate the models for invariant sets .Exploring the behaviour of PDE using bifurcation theory which provides many challenges both numerically and analytically.

Advanced and sophisticated techniques were used to confirm the synthesis, size, and shape of these NPs. Rounded, clustered NPs of size 5.343 nm were formed. Both the plain and core shell NPs were tested against MDR bacteria (E. cloacae, E. amnigenus, Shigella, S. odorifacae, Citrobacter, and E. coli). Both of the NPs showed excellent antibacterial properties, whereas E. cloacae showed maximum zone of inhibition of 16 mm, 27 mm, and 32 mm for 500 μg/ml, 1000 μg/ml, and 1500 μg/ml, respectively for plain ZnO NPs and 18 mm, 28 mm and 35 mm for 500 μg/ml, 1000 μg/ml and 1500 μg/ml for core shell NPs. These NPs were also biocompatible on human red blood cells showing little hemolysis of only 4% for 70 μg/ml for plain NPs and 1.5% for 70 μg/ml for core shell NPs. Core shell NPs were highly biocompatible because of the PEG. Their therapeutic effect as photosensitizers in photodynamic therapy (PDT) for cancer treatment was also monitored. The cytotoxicity of ZnO and PEG-ZnO was evaluated using MTT assay. Our results demonstrated that these NPs could generate ROS inside tumor cells after irradiation which in turn initiates an apoptotic pathway leading to cell death hence proving to be an effective candidate for PDT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ZnO" title="ZnO">ZnO</a>, <a href="https://publications.waset.org/abstracts/search?q=hemolysis" title=" hemolysis"> hemolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=cytotoxiciy%20assay" title=" cytotoxiciy assay"> cytotoxiciy assay</a>, <a href="https://publications.waset.org/abstracts/search?q=photodynamic%20therapy" title=" photodynamic therapy"> photodynamic therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=antibacterial" title=" antibacterial"> antibacterial</a> </p> <a href="https://publications.waset.org/abstracts/153973/controlled-size-synthesis-of-zno-and-peg-zno-nps-and-their-biological-evaluation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153973.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">140</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">1016</span> Sirhindi Family's Islamic Movements in Sindh, Pakistan </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nasurullah%20Qureshi">Nasurullah Qureshi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Shaikh Ahmad Sirhindi Mujadid Alif Thani (1564-1624) and his philosophy had influenced sub-continent as the whole; its rulers and nation.

The harmonic and ripple contents of the output DC voltage supplied by high voltage DC circuits require the use of costly capacitors to smooth the output voltage after rectification. This paper proposes a new modular multiplier high voltage DC generator with embedded Cockcroft-Walton circuits that achieve a negligible harmonic and ripple contents of the output DC voltage without the need for costly filters to produce a nearly constant output voltage. In this new topology, Cockcroft-Walton modules are connected in series to produce a high DC output voltage. The modules are supplied by low input AC voltage sources that have the same magnitude and frequency and shifted from each other by a certain angle to eliminate the harmonics from the output voltage. The small ripple factor is provided by the smoothing column capacitors and the phase shifted input voltages of the cascaded modules. The constituent harmonics within each module are determined using Fourier analysis. The viability of the proposed DC generator for testing purposes and the effectiveness of the cascaded connection are confirmed by numerical simulations using MATLAB/Simulink. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cockcroft-Walton%20circuit" title="Cockcroft-Walton circuit">Cockcroft-Walton circuit</a>, <a href="https://publications.waset.org/abstracts/search?q=harmonics" title=" harmonics"> harmonics</a>, <a href="https://publications.waset.org/abstracts/search?q=ripple%20factor" title=" ripple factor"> ripple factor</a>, <a href="https://publications.waset.org/abstracts/search?q=HVDC%20generator" title=" HVDC generator"> HVDC generator</a> </p> <a href="https://publications.waset.org/abstracts/93486/modular-harmonic-cancellation-in-a-multiplier-high-voltage-direct-current-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93486.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">367</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">1013</span> Assessment of Solid Insulating Material Using Partial Discharge Characteristics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qasim%20Khan">Qasim Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Furkan%20Ahmad"> Furkan Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Asfar%20A.%20Khan"> Asfar A.

As the number of portable electronics devices increases, the demand for more flexible and reliable charging techniques is becoming more urgent. A wireless battery charger differs from a traditional charger in the way the power transferred to the battery. In the latter, the power is transferred through electrical wires that connect the charger terminals to the battery terminals, while in the former; the power is transferred by induction without electrical connections. With a detection algorithm that detects the battery size and chemistry, the proposed charger will be able to accommodate a wide range of applications, and will allow a more flexible and reliable option to most of today’s portable electronics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=efficiency" title="efficiency">efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetically-coupled%20resonators" title=" magnetically-coupled resonators"> magnetically-coupled resonators</a>, <a href="https://publications.waset.org/abstracts/search?q=resonance%20frequency" title=" resonance frequency"> resonance frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20power%20transfer" title=" wireless power transfer"> wireless power transfer</a> </p> <a href="https://publications.waset.org/abstracts/43549/design-of-a-universal-wireless-battery-charger" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43549.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">455</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">1010</span> Effect of Iron Contents on Rheological Properties of Syndiotactic Polypropylene/iron Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naveed%20Ahmad">Naveed Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Farooq%20Ahmad"> Farooq Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Aal"> Abdul Aal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effect of iron contents on the rheological behavior of sPP/iron composites in the melt phase was investigated using a series of syndiotactic polypropylene/iron (sPP/iron) composite samples.

Among biotic factors, Phytoplasma infection induces abnormality influencing the physiology as well as morphology of plants. In 16Sr-IX group phytoplasma-infected brassica compestris, flower abnormalities have been associated with changes in the expression of floral development genes. To determine whether methylation was involved in down-regulation of flower development, the process of DNA methylation and Demethylation was investigated as a possible mechanism for regulation of floral gene expression in phytoplasma infected Brassica transmitted by Orosious orientalis vector by using RT-PCR, MSRE-PCR, Southern blotting, Bisulfite Sequencing, etc. Transcriptional expression of methylated genes was found to be globally down-regulated in plants infected with phytoplasma, but not severely in those infested by insect vectors and variation in expression was found in genes involved in methylation. These results also showed that genes particularly orthologous to Arabidopsis APETALA3 involved in petal formation and flower development was down-regulated severely in phytoplasma-infected brassica and with the fact that phytoplasma and insect induce variation in developmental gene expression. The DNA methylation status of flower developmental gene in phytoplasma infected plants with 5-azacytidine restored gene expression strongly suggesting that DNA methylation was involved in down-regulation of floral development genes in phytoplasma infected brassica. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genes%20expression" title="genes expression">genes expression</a>, <a href="https://publications.waset.org/abstracts/search?q=phytoplasma" title=" phytoplasma"> phytoplasma</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20methylation" title=" DNA methylation"> DNA methylation</a>, <a href="https://publications.waset.org/abstracts/search?q=flower%20development" title=" flower development"> flower development</a> </p> <a href="https://publications.waset.org/abstracts/87401/study-on-developmental-and-pathogenesis-related-genes-expression-deregulation-in-brassica-compestris-infected-with-16sr-ix-associated-phytoplasma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87401.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">374</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">1007</span> Effect of Bull Exposure on Post-Partum Estrus Interval in Nili-Ravi Buffaloes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Saleem%20Akhtar">Muhammad Saleem Akhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mushtaq%20Hussain%20Lashari"> Mushtaq Hussain Lashari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ejaz%20Ahmad"> Ejaz Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanveer%20Ahmad"> Tanveer Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Laeeq%20Akbar%20Lodhi"> Laeeq Akbar Lodhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ijaz%20Ahmad"> Ijaz Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Masood%20Akhtar"> Masood Akhtar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study was to determine the effect of bull exposure continuously or intermittently or its excretory products after calving on postpartum interval to estrus, in Nili-Ravi buffalo. Forty-eight buffaloes of Nili-Ravi breed were allocated one of the four treatments in a totally randomized plan using a 4 x 1 factorial design. The four treatment groups were BEC (Bull Exposed Continuously), BEI (Bull Exposed Intermittently), EPB (Excretory Products of Bull) and BNE (Bull Not Exposed). BEC; buffaloes (n = 12) were exposed continuously to the physical presence of a bull whereas in BEI; buffaloes (n = 12) were exposed intermittently to the physical presence of bull. EPB; buffaloes (n = 12) were exposed to discharge waste (urine and feces) of bull and BNE buffaloes (n = 12) were not exposed to a bull or discharge waste of bulls. Buffaloes were exposed on day 15 after parturition. Day 15 postpartum represented d 0 for each treatment. The postpartum interval from calving to first behavioural estrus was 66.88 days in BEC, 75.12 days in BEI, 77.28 days in EPB and 76.5 days in BNE treatments. Postpartum interval to first behavioural estrus was shorter in BEC than BEI, EPB, and BNE treatments. There was no significant difference in postpartum interval to estrus between BEI, EPB and BNE treatments. In present study, the percentage of buffaloes showing estrus during experimental period was 75.0%, 66.66%, 66.66% and 58.33% in BEC, BEI, EPB and BNE treatments, respectively. The mean serum progesterone concentration did not differ significantly between BEC and other (BEI, EPB, and BNE) treatments. It was concluded that presence of bull has positive effect in reducing calving interval in Nili Ravi buffalo. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calving%20interval" title="calving interval">calving interval</a>, <a href="https://publications.waset.org/abstracts/search?q=biostimulation" title=" biostimulation"> biostimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=buffalo" title=" buffalo"> buffalo</a>, <a href="https://publications.waset.org/abstracts/search?q=bull%20exposure" title=" bull exposure"> bull exposure</a> </p> <a href="https://publications.waset.org/abstracts/100620/effect-of-bull-exposure-on-post-partum-estrus-interval-in-nili-ravi-buffaloes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100620.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">256</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">1006</span> Parametric Screening and Design Refinement of Ceiling Fan Blades</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shamraiz%20Ahmad">Shamraiz Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Riaz%20Ahmad"> Riaz Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Adnan%20Maqsood"> Adnan Maqsood</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes the application of 2k-design of experiment in order to screen the geometric parameters and experimental refinement of ceiling fan blades.

The writing of fables, in prose and verse, was widely cultivated not only in pre-Islamic Arabia but also in the middle ages, reaching its culmination with the Egyptian poet and man of letters Ahmad Shawqī (1989-1932), who revived the ancient tradition, a relatively minor and unexploited genre in the modern era, and re-wrote rimed fables with an Arab Islamic flavor, articulating a set of modern ethico-political concepts and sensibilities such as a belief in good judgment in governance, individual liberty, democracy, a sense of the brotherhood of man and justice. This essay aims to restore the 20th Century poet to his rightful place in the international pantheon of literary achievement, and offers an examination of the Arabian fabulist tradition as it appears in Arabic literature, and a treatment of this genre re-visiting a few representative samples of Ahmad Shawqī collection of fables and their implications for contemporary politics in the Middle East. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fable" title="fable">fable</a>, <a href="https://publications.waset.org/abstracts/search?q=politcs" title=" politcs"> politcs</a>, <a href="https://publications.waset.org/abstracts/search?q=governace" title=" governace"> governace</a>, <a href="https://publications.waset.org/abstracts/search?q=democracy" title=" democracy"> democracy</a>, <a href="https://publications.waset.org/abstracts/search?q=ethics%20of%20care" title=" ethics of care "> ethics of care </a> </p> <a href="https://publications.waset.org/abstracts/28913/arabic-fables-in-contemporary-garbs-ahmed-shawqis-reconstruction-of-fables-in-the-modern-era" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28913.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">676</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">1004</span> Social Media and Student-Teacher Relationship: A Case Study Form Kashmir University</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wahid%20Ahmad%20Dar">Wahid Ahmad Dar</a>, <a href="https://publications.waset.org/abstracts/search?q=Irshad%20Ahmad%20Najar"> Irshad Ahmad Najar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The influence of social media is percolating to every corner of our social life. It is also changing the social sphere of the classroom in particular and education in general. This paper tries to explore the ways in which social media is influencing student-teacher relationship. Differences have been found in student’s ability to draw benefits from using ICT. Besides digital divides in access and usage, there are attitudinal differences among students towards ICT aligned with traditional forms of social differences. The paper particularly focusses on how students from diverse backgrounds are using social media to interact with their teachers and how such interactions differ on the basis of social class, gender and residential background of students. A qualitative research methodology has been used for answering these questions. Open-ended questionnaire has been designed and administered to a sample of postgraduate students from University of Kashmir drawn purposively ensuring optimum number of subjects from all backgrounds.

This paper provides a comprehensive overview of the current state of IoT-based information processing and computing, as well as the key challenges and gaps that need to be addressed. This paper discusses the potential benefits of IoT-based information processing and computing, such as improved efficiency, enhanced decision-making, and cost savings. Despite the numerous benefits of IoT-based information processing and computing, several challenges need to be addressed to realize the full potential of these systems. These challenges include security and privacy concerns, interoperability issues, scalability and reliability of IoT devices, and the need for standardization and regulation of IoT technologies. Moreover, this paper identifies several gaps in the current research related to IoT-based information processing and computing.

The modified diatomite was added to soil samples at the rates of 2.5, 5, 7.5 and 10% and the samples incubated for 60 days. The addition of modified diatomite increased SSA of the soil. The SSAs of soils with 2.5, 5.0, 7.5 and 10% modified diatomite were 20.82, 22.02, 23.21 and 24.41 m² g-¹ respectively. Increasing the SSAs of the soils by the application of modified diatomite reduced the DTPA extractable concentrations of heavy metals compared with un-amendment control. The concentration of Pb, Zn and Cu were reduced by 91.1%, 82% and 91.1% respectively. Modified diatomite reduced the concentration of Exchangeable and Carbonate bounded species of Pb, Zn and Cu, compared with the control. Also significantly increased the concentration of Fe Mn- OX (Fe-Mn Oxides) and OM (Organic Matter) bound and Res (Residual) fraction. Modified diatomite increased the urease, dehydrogenase and alkaline phosphatase activity by 52%, 57% and 56.6% respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modified%20diatomite" title="modified diatomite">modified diatomite</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20specifications" title=" chemical specifications"> chemical specifications</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20surface%20area" title=" specific surface area"> specific surface area</a>, <a href="https://publications.waset.org/abstracts/search?q=enzyme%20activity" title=" enzyme activity"> enzyme activity</a>, <a href="https://publications.waset.org/abstracts/search?q=immobilization" title=" immobilization"> immobilization</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal" title=" heavy metal"> heavy metal</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20remediation" title=" soil remediation"> soil remediation</a> </p> <a href="https://publications.waset.org/abstracts/180554/soil-rehabilitation-using-modified-diatomite-assessing-chemical-properties-enzymatic-reactions-and-heavy-metal-immobilization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/180554.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">64</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">1000</span> Available Transmission Transfer Efficiency (ATTE) as an Index Measurement for Power Transmission Grid Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Abubakar%20Sadiq">Ahmad Abubakar Sadiq</a>, <a href="https://publications.waset.org/abstracts/search?q=Nwohu%20Ndubuka%20Mark"> Nwohu Ndubuka Mark</a>, <a href="https://publications.waset.org/abstracts/search?q=Jacob%20Tsado"> Jacob Tsado</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Adam%20Asharaf"> Ahmad Adam Asharaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Agbachi%20E.%20Okenna"> Agbachi E.

Key performance indicators (KPIs) are often used as measure of degree of performance. This paper gives a novel method to determine the transmission efficiency by evaluating the ratio of real power losses incurred from a specified transfer direction. Available Transmission Transfer Efficiency (ATTE) expresses the percentage of real power received resulting from inter-area available power transfer. The Tie line (Rated system path) performance is seen to differ from system wide (Network response) performance and ATTE values obtained are transfer direction specific. The required sending end quantities with specified receiving end ATC and the receiving end power circle diagram are obtained for the tie line analysis. The amount of real power loss load relative to the available transfer capability gives a measure of the transmission grid efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=performance" title="performance">performance</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20system" title=" transmission system"> transmission system</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20power%20%0D%0Aefficiency" title=" real power efficiency"> real power efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=available%20transfer%20capability" title=" available transfer capability"> available transfer capability</a> </p> <a href="https://publications.waset.org/abstracts/24119/available-transmission-transfer-efficiency-atte-as-an-index-measurement-for-power-transmission-grid-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24119.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">649</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">999</span> Thermophysical and Heat Transfer Performance of Covalent and Noncovalent Functionalized Graphene Nanoplatelet-Based Water Nanofluids in an Annular Heat Exchanger</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamed%20K.%20Arzani">Hamed K.

To realize this goal, graphene nanoplatelet-based water nanofluids with promising thermophysical properties were synthesized in the presence of covalent and noncovalent functionalization. Thermal conductivity, density, viscosity and specific heat capacity were investigated and employed as a raw data for ANSYS-Fluent to be used in two-phase approach. After validation of obtained results by analytical equations, two special parameters of convective heat transfer coefficient and pressure drop were investigated. The study followed by studying other heat transfer parameters of annular pass in the presence of graphene nanopletelesbased water nanofluids at different weight concentrations, input powers and temperatures. As a result, heat transfer performance and friction loss are predicted for both synthesized nanofluids. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title="heat transfer">heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofluid" title=" nanofluid"> nanofluid</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulent%20flow" title=" turbulent flow"> turbulent flow</a>, <a href="https://publications.waset.org/abstracts/search?q=forced%20convection%20flow" title=" forced convection flow"> forced convection flow</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20nanoplatelet" title=" graphene nanoplatelet"> graphene nanoplatelet</a> </p> <a href="https://publications.waset.org/abstracts/44845/thermophysical-and-heat-transfer-performance-of-covalent-and-noncovalent-functionalized-graphene-nanoplatelet-based-water-nanofluids-in-an-annular-heat-exchanger" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44845.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">432</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">998</span> Local Spectrum Feature Extraction for Face Recognition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Imran%20Ahmad">Muhammad Imran Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruzelita%20Ngadiran"> Ruzelita Ngadiran</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Nazrin%20Md%20Isa"> Mohd Nazrin Md Isa</a>, <a href="https://publications.waset.org/abstracts/search?q=Nor%20Ashidi%20Mat%20Isa"> Nor Ashidi Mat Isa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20ZaizuIlyas"> Mohd ZaizuIlyas</a>, <a href="https://publications.waset.org/abstracts/search?q=Raja%20Abdullah%20Raja%20Ahmad"> Raja Abdullah Raja Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Amirul%20Anwar%20Ab%20Hamid"> Said Amirul Anwar Ab Hamid</a>, <a href="https://publications.waset.org/abstracts/search?q=Muzammil%20Jusoh"> Muzammil Jusoh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents two technique, local feature extraction using image spectrum and low frequency spectrum modelling using GMM to capture the underlying statistical information to improve the performance of face recognition system. Local spectrum features are extracted using overlap sub block window that are mapping on the face image. For each of this block, spatial domain is transformed to frequency domain using DFT. A low frequency coefficient is preserved by discarding high frequency coefficients by applying rectangular mask on the spectrum of the facial image. Low frequency information is non Gaussian in the feature space and by using combination of several Gaussian function that has different statistical properties, the best feature representation can be model using probability density function. The recognition process is performed using maximum likelihood value computed using pre-calculate GMM components. The method is tested using FERET data sets and is able to achieved 92% recognition rates. <p class="card-text"><strong>Keywords:</strong> <a
