FL utilizes three distinct architectures to ensure privacy is never compromised. It involves training individual edge devices and aggregating their models on a server without sharing raw data. This approach not only provides secure models without data sharing but also offers a highly efficient privacy--preserving solution with improved security and data access. Also we discusses various frameworks used in FL and its integration with machine learning, deep learning, and data mining. In order to address the challenges of multi--party collaborative modeling scenarios, a brief review FL scheme combined with an adaptive gradient descent strategy and differential privacy mechanism. The adaptive learning rate algorithm adjusts the gradient descent process to avoid issues such as model overfitting and fluctuations, thereby enhancing modeling efficiency and performance in multi-party computation scenarios. Additionally, to cater to ultra-large-scale distributed secure computing, the research introduces a differential privacy mechanism that defends against various background knowledge attacks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=federated%20learning" title="federated learning">federated learning</a>, <a href="https://publications.waset.org/abstracts/search?q=differential%20privacy" title=" differential privacy"> differential privacy</a>, <a href="https://publications.waset.org/abstracts/search?q=gradient%20descent%20strategy" title=" gradient descent strategy"> gradient descent strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=convergence" title=" convergence"> convergence</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=threats" title=" threats"> threats</a> </p> <a href="https://publications.waset.org/abstracts/187891/convergence-and-stability-in-federated-learning-with-adaptive-differential-privacy-preservation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187891.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">30</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">60</span> Catalytic Study of Natural Gas Based Solid Oxide Fuel Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nasir%20Iqbal">Nasir Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Khurram%20Siraj"> Khurram Siraj</a>, <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Raza"> Rizwan Raza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Solid oxide fuel cell (SOFC) is the promising technology now days.

The stresses may be biotic or/and abiotic. These environmental stresses have adverse effects on photosynthesis, water relation and nutrients uptake of plants. Fertilization of plants with exogenous minerals can enhance the drought tolerance in plants. In this experiment, canola (Brassica napus) was treated with solutions of calcium nitrate in different concentrations before the imposition of drought stress for 10 days. It was observed that drought stress decreased the tissue-K, Ca and K/Ca ratio of canola seedlings. The tissue-carbon and nitrogen contents were also depressed by the drought stress. Application of calcium nitrate, however, could alleviate the adverse effects of drought stress by showing a positive effect on all the aforementioned parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brassica%20napus" title="Brassica napus">Brassica napus</a>, <a href="https://publications.waset.org/abstracts/search?q=calcium" title=" calcium"> calcium</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon" title=" carbon"> carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=potassium" title=" potassium "> potassium </a> </p> <a href="https://publications.waset.org/abstracts/4996/minerals-of-canola-brassica-napus-as-affected-by-water-stress-and-applied-calcium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4996.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">526</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">57</span> Municipal Sewage Sludge as Co-Substrate in Anaerobic Digestion of Vegetable Waste and Biogas Yield</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20V.%20Thanikal">J.

The anaerobic co-digestion process, which can be defined as the simultaneous treatment of two –or more – organic biodegradable waste streams by anaerobic digestion offers great potential for the proper disposal of the organic fraction of solid waste coming from source or separate collection systems. The results of biogas production for sewage sludge, when used as a single substrate, were low (350ml/d), and also the biodegradation rate was slow. Sewage sludge as a co-substrate did not show much effect on biogas yield.

There have been several remarkable studies on spokes-characters in advertising effectiveness. However, few studies have examined the link between character presence and consumers' brand recall and attitude in advergame. Moreover, how the entertainment value of an advergame influences brand recall and brand attitude and the mediating role of brand recall in influencing character presence and entertainment on brand attitude are still lacking in the advergaming literature. An online survey was conducted with 366 Malaysian gamers. Using structural equation modeling, the results showed that character presence had no influence but entertainment value had a positive influence on brand recall and brand attitude. This study confirmed the role of brand recall as a mediator of the effect of between entertainment and brand attitude in advergame. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=character%20presence" title="character presence">character presence</a>, <a href="https://publications.waset.org/abstracts/search?q=entertainment" title=" entertainment"> entertainment</a>, <a href="https://publications.waset.org/abstracts/search?q=brand%20recall" title=" brand recall"> brand recall</a>, <a href="https://publications.waset.org/abstracts/search?q=brand%20attitude" title=" brand attitude"> brand attitude</a>, <a href="https://publications.waset.org/abstracts/search?q=advergame" title=" advergame"> advergame</a> </p> <a href="https://publications.waset.org/abstracts/20513/the-relationship-between-brand-recall-and-brand-attitude-in-advergame" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20513.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">536</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">53</span> Impact of Meaning in Life on Stress and Psychological Well-Being</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aisha%20Bano">Aisha Bano</a>, <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Nazir"> Rizwan Nazir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study aimed at exploring the impact of meaning in life on psychological well-being and stress among university students. Victor Frankl's paradigm provided the theoretical foundation for this study. A sample of 560 university students was drawn from Quaid-i-Azam University Islamabad. The sample was drawn using stratified random sampling technique. Data were collected using Existence Scale, Warwick-Edinburg Mental Well-Being Scale, and Stress Scale. Results of linear regression analysis reveals that high perception of meaning in life will lead to high psychological well-being and low stress among university students. Non-significant differences are found on meaning in life variable with regard to gender in the sample using t-test. Together these results suggest that meaning in life independent of gender, is a significant predictor of the levels of stress and psychological well-being being directly related to psychological well-being and inversely related to stress levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=existential%20meaning%20in%20life" title="existential meaning in life">existential meaning in life</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20well-being" title=" psychological well-being"> psychological well-being</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=students" title=" students"> students</a> </p> <a href="https://publications.waset.org/abstracts/2541/impact-of-meaning-in-life-on-stress-and-psychological-well-being" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2541.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">506</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">52</span> Geotechnical Distress Evaluation of a Damaged Structure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zulfiqar%20Ali">Zulfiqar Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Umar%20Saleem"> Umar Saleem</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Junaid"> Muhammad Junaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Tahir"> Rizwan Tahir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gulzar Mahal is a heritage site located in the city of Bahawalpur, Pakistan. The site is under a process of degradation, as cracks are appearing on the walls, roofs, and floor around the building due to differential settlement. To preserve the integrity of the structure, a geotechnical distress evaluation was carried out to evaluate the causal factors and recommend remediation measures. The research involved the characterization of the problematic soil and analysis of the observed distress with respect to the geotechnical properties. Both conventional lab and field tests were used in conjunction with the unconventional techniques like; Electrical Resistivity Tomography (ERT) and FEA. The temporal, geophysical and geotechnical evaluations have concluded that the foundation soil over the past was subjected to variations in the land use, poor drainage patterns, overloading and fluctuations in groundwater table all contributing to the differential settlements manifesting in the form of the visible shear crack across the length and breadth of the building. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=differential%20settlement" title="differential settlement">differential settlement</a>, <a href="https://publications.waset.org/abstracts/search?q=distress%20evaluation" title=" distress evaluation"> distress evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Gulzar%20Mahal" title=" Gulzar Mahal"> Gulzar Mahal</a> </p> <a href="https://publications.waset.org/abstracts/121679/geotechnical-distress-evaluation-of-a-damaged-structure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121679.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">127</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">51</span> DC-to-DC Converters for Low-Voltage High-Power Renewable Energy Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdar%20Ali">Abdar Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Ullah"> Rizwan Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahid%20Ullah"> Zahid Ullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper focuses on the study of DC-to-DC converters, which are suitable for low-voltage high-power applications. The output voltages generated by renewable energy sources such as photovoltaic arrays and fuel cell stacks are generally low and required to be increased to high voltage levels. Development of DC-to-DC converters, which provide high step-up voltage conversion ratios with high efficiencies and low voltage stresses is one of the main issues in the development of renewable energy systems. A procedure for three converters-conventional DC-to-DC converter, interleaved boost converter, and isolated flyback based converter, is illustrated for a given set of specifications. The selection among the converters for the given application is based on the voltage conversion ratio, efficiency, and voltage stresses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flyback%20converter" title="flyback converter">flyback converter</a>, <a href="https://publications.waset.org/abstracts/search?q=interleaved%20boost" title=" interleaved boost"> interleaved boost</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20array" title=" photovoltaic array"> photovoltaic array</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20cell" title=" fuel cell"> fuel cell</a>, <a href="https://publications.waset.org/abstracts/search?q=switch%20stress" title=" switch stress"> switch stress</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20conversion%20ratio" title=" voltage conversion ratio"> voltage conversion ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a> </p> <a href="https://publications.waset.org/abstracts/32572/dc-to-dc-converters-for-low-voltage-high-power-renewable-energy-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32572.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">597</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">50</span> Development of a One-Window Services Model for Accessing Cancer Immunotherapies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Arshad">Rizwan Arshad</a>, <a href="https://publications.waset.org/abstracts/search?q=Alessio%20Panza"> Alessio Panza</a>, <a href="https://publications.waset.org/abstracts/search?q=Nimra%20Inayat"> Nimra Inayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Syeda%20Mariam%20Batool%20Kazmi"> Syeda Mariam Batool Kazmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shawana%20Azmat"> Shawana Azmat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The rapidly expanding use of immunotherapy for a wide range of cancers from late to early stages has, predictably, been accompanied by evidence of inequities in access to these highly effective but costly treatments.

Permeability values for rock formations are more difficult for determination than soil formation as it is an effect of the rock quality and its fracture values. In this research, the prediction of in situ permeability of limestone rock formations was predicted. The limestone rock permeability was evaluated using Lugeon tests (in-situ packer permeability). Different sites which spread all over the Riyadh region of Saudi Arabia were chosen to conduct our study of predicting the in-situ permeability of limestone rock. Correlations were deducted between the values of in-situ permeability of the limestone rock with the value of the rock quality designation (RQD) calculated during the execution of the boreholes of the study areas. The study was performed for different ranges of RQD values measured during drilling of the sites boreholes. The developed correlations are recommended for the onsite determination of the in-situ permeability of limestone rock only. For the other sedimentary formations of rock, more studies are needed for predicting the actual correlations related to each type. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=In%20situ" title="In situ">In situ</a>, <a href="https://publications.waset.org/abstracts/search?q=packer" title=" packer"> packer</a>, <a href="https://publications.waset.org/abstracts/search?q=permeability" title=" permeability"> permeability</a>, <a href="https://publications.waset.org/abstracts/search?q=rock" title=" rock"> rock</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a> </p> <a href="https://publications.waset.org/abstracts/64850/prediction-of-in-situ-permeability-for-limestone-rock-using-rock-quality-designation-index" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64850.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">48</span> Paucity of Trauma Literature from a Highly Burdened Developing Country</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Sultan">Rizwan Sultan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasnain%20Zafar"> Hasnain Zafar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Trauma is the leading cause of death among young population not only in USA but Pakistan as well.

Search using term “Trauma AND Pakistan” filtering for relevant dates and species human was done on Pubmed. The abstracts and articles were reviewed by the authors to collect data on a preformed performa. 114 articles were published from Pakistan during these 5 years. 64% articles were published in international journals. 63% articles were published in journals with impact factor less than 1. 54% articles were published from one of the four provinces of Pakistan. 64% of articles provided level 4 while 14% articles provided level 5 evidence on the topic. 55% articles discussed epidemiology in non-representative populations. Trauma literature from Pakistan is not only lacking significantly but is also of poor quality and is unable to offer conclusions on this particular subject.

Therapeutic compounds which can diminish or disaggregate such toxic oligomers and fibrillar species have been examined and more are on its way. In the present study, we had reported an extensive biophysical, microscopic and computational study, revealing that L-3, 4-dihydroxyphenylalanine (L-Dopa) possess undeniable potency to inhibit heat induced human lysozyme (HL) amyloid fibrillation and also retain the fibril disaggregating potential. L-Dopa interferes in the amyloid fibrillogenesis process by interacting hydrophobically and also by forming hydrogen bonds with the amino acid residues found in amyloid fibril forming prone region of HL as elucidated by molecular docking results. L-Dopa also disaggregates the mature amyloid fibrils into some unorganised species. Thus, L-Dopa and related compounds can work as a promising inhibitor for the therapeutic advancement prospective against systemic amyloidosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amyloids" title="amyloids">amyloids</a>, <a href="https://publications.waset.org/abstracts/search?q=disaggregation" title=" disaggregation"> disaggregation</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20lysozyme" title=" human lysozyme"> human lysozyme</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20docking" title=" molecular docking"> molecular docking</a> </p> <a href="https://publications.waset.org/abstracts/67120/molecular-basis-for-amyloid-inhibition-by-l-dopa-implication-towards-systemic-amyloidosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67120.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">327</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">46</span> In-Vitro Stability of Aspergillus terreus Phytases in Relation to Different Physico-Chemical Factors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qaiser%20Akram">Qaiser Akram</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahsan%20Naeem"> Ahsan Naeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafiz%20Muhammad%20Rizwan"> Hafiz Muhammad Rizwan</a>, <a href="https://publications.waset.org/abstracts/search?q=Waqas%20Ahmad"> Waqas Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Rubeena%20Yasmeen"> Rubeena Yasmeen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aspergillus has good secretory potential for phytases. Morphologically and microscopically identified Aspergillus terreus (A. terreus) (n=20) were screened for phytase production and non-toxicity. Phytases produced by non-toxigenic A. terreus under optimum conditions were quantified. Phytases of highest producer A. terreus were evaluated for stability after exposure to temperature (35, 55, 75 and 95ºC) and pH (2, 4, 6 and 8). Effect of metal ions (Fe⁺³, Ba⁺², Ca⁺², Cu⁺², Mg⁺², Mn⁺², K⁺¹ and Na⁺¹) was assessed on phytase activity. Log reduction in phytase activity was calculated. The highest activity units of phytase produced by A. terreus were 271.49 ± 8.14 phytase unit / mL (FTU/ mL). The lowest reduction in phytase activity was 50.20 ± 7.36 (18.5%) and 68.22 ± 10.3 FTU/mL (25.13%) at 35ºC and pH 6, respectively for 15 minutes. The highest reduction 259 ± 0.84 (95.5%) and 211.99 ± 4.39 FTU/mL (78.1%) was recorded at 95ºC for 60 minutes and pH 2.0 for 45 minutes exposure, respectively. All metal ions negatively affected phytase activity. Phytase activity was inhibited minimum (45.32 ± 28.54 FTU/mL, 16.69%) by K⁺¹(1 mM) and maximum (231.48 ± 3.68 FTU/mL, 80.8%) by Cu⁺² (10 mM). It was concluded that A. terreus phytase stability and activity was dependent on physio-chemical factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stability" title="stability">stability</a>, <a href="https://publications.waset.org/abstracts/search?q=phytase" title=" phytase"> phytase</a>, <a href="https://publications.waset.org/abstracts/search?q=aspergillus%20terreus" title=" aspergillus terreus"> aspergillus terreus</a>, <a href="https://publications.waset.org/abstracts/search?q=physio-chemical%20factors%20and%20metal%20ions" title=" physio-chemical factors and metal ions"> physio-chemical factors and metal ions</a> </p> <a href="https://publications.waset.org/abstracts/159065/in-vitro-stability-of-aspergillus-terreus-phytases-in-relation-to-different-physico-chemical-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159065.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">287</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">45</span> Influence of Single Source Irradiation on the Homogeneous Alignment of Liquid Crystals Molecules on Glass Substrates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Akhtar">Sarah Akhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Mahmood"> Rizwan Mahmood</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A detailed study of homogeneous alignment of liquid crystal molecules on a glass substrate will be presented. Thin films of polyimide were coated on several glass substrates. Various methods were employed to prepare coated surfaces to achieve desired alignment; these include traditionally rubbing the surface with a felt cloth then exposing them perpendicular to the easy axis with incandescent light (IL), linearly polarized ultraviolet (LPUVR) and un-polarized ultraviolet (UPUVR) radiation. The quality of the alignment was tested by measuring the tilt angle in the temperature range between 30°C to 55°C. Regression analysis of the data using ‘SigmaPlot’ suggests a gradual increase in tilt angle (1.1°-1.8°) for the rubbed, 0.6° to 3.6° increase for the rubbed plus IL radiated and 1.6° to 4.6° for the rubbed plus UPUVL radiated samples, respectively. However to our surprise, we found tilt angle to be decreasing from 2.4° to 1.6° for the rubbed plus LPUVL radiated samples. We hope that these findings will be helpful in the fabrication of display panels and other electro-optic devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=homogeneous" title="homogeneous">homogeneous</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20crystals" title=" liquid crystals"> liquid crystals</a>, <a href="https://publications.waset.org/abstracts/search?q=polyimide" title=" polyimide"> polyimide</a>, <a href="https://publications.waset.org/abstracts/search?q=tilt%20angle" title=" tilt angle"> tilt angle</a> </p> <a href="https://publications.waset.org/abstracts/102033/influence-of-single-source-irradiation-on-the-homogeneous-alignment-of-liquid-crystals-molecules-on-glass-substrates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102033.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">118</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">44</span> The Effect of Fly Ash and Natural Pozzolans on the Quality of Passive Oxide Film Developed on Steel Reinforcement Bars </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.S.%20Ashraf">M.S.

Climate change and continuously depleting resources are the key driving forces to think for alternative sources of energy. Macroalgae can be favored over land based energy crops because they are not in direct competition with food crops. However, some drawbacks, such as high moisture content, seasonal variation in chemical composition and process inhibition limit the economic practicability. Macroalgae, like brown seaweed can be converted into gaseous and liquid fuel by different conversion technologies. Biomethane via anaerobic digestion is the appealing technology due to its dual advantage of a commercially applicable and environment friendly technology. Other technologies like biodiesel and bioethanol conversion technologies from seaweed are still under progress. Screening of high yielding macroalgae species, peak harvesting season and process optimization make the technology economically feasible for alternative source of feedstock for biofuel production in future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title="anaerobic digestion">anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=biofuels" title=" biofuels"> biofuels</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-methane" title=" bio-methane"> bio-methane</a>, <a href="https://publications.waset.org/abstracts/search?q=advanced%20conversion%20technologies" title=" advanced conversion technologies"> advanced conversion technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=macroalgae" title=" macroalgae "> macroalgae </a> </p> <a href="https://publications.waset.org/abstracts/44992/macroalgae-as-a-gaseous-fuel-option-potential-and-advanced-conversion-technologies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44992.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">307</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">42</span> Zero Voltage Switched Full Bridge Converters for the Battery Charger of Electric Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Ullah">Rizwan Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdar%20Ali"> Abdar Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahid%20Ullah"> Zahid Ullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper illustrates the study of three isolated zero voltage switched (ZVS) PWM full bridge (FB) converters to charge the high voltage battery in the charger of electric vehicle (EV). EV battery chargers have several challenges such as high efficiency, high reliability, low cost, isolation, and high power density. The cost of magnetic and filter components in the battery charger is reduced when switching frequency is increased. The increase in the switching frequency increases switching losses. ZVS is used to reduce switching losses and to operate the converter in the battery charger at high frequency. The performance of each of the three converters is evaluated on the basis of ZVS range, dead times of the switches, conduction losses of switches, circulating current stress, circulating energy, duty cycle loss, and efficiency. The limitations and merits of each PWM FB converter are reviewed. The converter with broader ZVS range, high efficiency and low switch stresses is selected for battery charger applications in EV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicle" title="electric vehicle">electric vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=PWM%20FB%20converter" title=" PWM FB converter"> PWM FB converter</a>, <a href="https://publications.waset.org/abstracts/search?q=zero%20voltage%20switching" title=" zero voltage switching"> zero voltage switching</a>, <a href="https://publications.waset.org/abstracts/search?q=circulating%20energy" title=" circulating energy"> circulating energy</a> </p> <a href="https://publications.waset.org/abstracts/54708/zero-voltage-switched-full-bridge-converters-for-the-battery-charger-of-electric-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54708.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">439</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Optimal Allocation of Distributed Generation Sources for Loss Reduction and Voltage Profile Improvement by Using Particle Swarm Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Zaheer%20Babar">Muhammad Zaheer Babar</a>, <a href="https://publications.waset.org/abstracts/search?q=Amer%20Kashif"> Amer Kashif</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Rizwan%20Javed"> Muhammad Rizwan Javed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays distributed generation integration is best way to overcome the increasing load demand. Optimal allocation of distributed generation plays a vital role in reducing system losses and improves voltage profile. In this paper, a Meta heuristic technique is proposed for allocation of DG in order to reduce power losses and improve voltage profile. The proposed technique is based on Multi Objective Particle Swarm optimization. Fewer control parameters are needed in this algorithm. Modification is made in search space of PSO. The effectiveness of proposed technique is tested on IEEE 33 bus test system. Single DG as well as multiple DG scenario is adopted for proposed method. Proposed method is more effective as compared to other Meta heuristic techniques and gives better results regarding system losses and voltage profile. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Distributed%20generation%20%28DG%29" title="Distributed generation (DG)">Distributed generation (DG)</a>, <a href="https://publications.waset.org/abstracts/search?q=Multi%20Objective%20Particle%20Swarm%20Optimization%20%28MOPSO%29" title=" Multi Objective Particle Swarm Optimization (MOPSO)"> Multi Objective Particle Swarm Optimization (MOPSO)</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization%20%28PSO%29" title=" particle swarm optimization (PSO)"> particle swarm optimization (PSO)</a>, <a href="https://publications.waset.org/abstracts/search?q=IEEE%20standard%20Test%20System" title=" IEEE standard Test System"> IEEE standard Test System</a> </p> <a href="https://publications.waset.org/abstracts/42467/optimal-allocation-of-distributed-generation-sources-for-loss-reduction-and-voltage-profile-improvement-by-using-particle-swarm-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42467.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">454</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> External Sector and Its Impact on Economic Growth of Pakistan (1990-2010)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Fazal">Rizwan Fazal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigates the behavior of external sector of Pakistan economy and its impact on economic growth, using quarterly data for the period 1990:01-2010:04.

Transition and adjustment from working life to retirement places create psychological pressure and financial distress on older workers, especially those with dependent children. Bridge employment provides a solution for older workers to continue working after retirement while transitioning into retirement slowly and smoothly. As losing the job role has a significant impact on the psychological well-being of retirees, engageing in bridge employment helps to fulfill the important psychological functions of older workers by providing an adaptive style to retirement. This study investigates the influence of retirement planning and job satisfaction on bridge employment. A self-administered questionnaire was used in this study and a total of 523 samples were collected for nine major district in Sabah. Data were analysed using Partial Least Square (PLS) method wersion 2.0. The result shows a significant relationship between retirement planning and job satisfaction on bridge employment, explaining 4.7% the variance in bridge employment and job satisfaction was found to be the strongest predictor of bridge employment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ageing%20population" title="ageing population">ageing population</a>, <a href="https://publications.waset.org/abstracts/search?q=retirement%20planning" title=" retirement planning"> retirement planning</a>, <a href="https://publications.waset.org/abstracts/search?q=job%20satisfaction" title=" job satisfaction"> job satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=bridge%20employment" title=" bridge employment"> bridge employment</a> </p> <a href="https://publications.waset.org/abstracts/30036/retirement-planning-and-job-satisfaction-cushion-to-avoid-bridge-employment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30036.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">360</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">38</span> Seaweed as a Future Fuel Option: Potential and Conversion Technologies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Rizwan%20Tabassum">Muhammad Rizwan Tabassum</a>, <a href="https://publications.waset.org/abstracts/search?q=Ao%20Xia"> Ao Xia</a>, <a href="https://publications.waset.org/abstracts/search?q=Jerry%20D.%20Murphy"> Jerry D.

Resource depletion and climate change are the driving forces to hunt for renewable sources of energy. Macroalgae can be preferred over land based crops for biofuel production because they are not in competition with food crops for arable land, high growth rates and low lignin contents which require less energy-intensive pre-treatments. However, some disadvantages, such as high moisture content, seasonal variation in chemical composition and process inhibition limit its economic feasibility. Seaweed can be converted into gaseous and liquid fuel by different conversion technologies, but biogas via anaerobic digestion from seaweed is attracting increased attention due to its dual benefit of an economic source of bio-fuel and environment-friendly technology. Biodiesel and bioethanol conversion technologies from seaweed are still under development. A selection of high yielding seaweed species, optimal harvesting season and process optimization make them economically feasible for the alternative source of renewable and sustainable feedstock for biofuel in future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title="anaerobic digestion">anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=biofuel" title=" biofuel"> biofuel</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-methane" title=" bio-methane"> bio-methane</a>, <a href="https://publications.waset.org/abstracts/search?q=conversion%20technologies" title=" conversion technologies"> conversion technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=seaweed" title=" seaweed"> seaweed</a> </p> <a href="https://publications.waset.org/abstracts/37226/seaweed-as-a-future-fuel-option-potential-and-conversion-technologies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37226.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">474</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">37</span> Behavior Factors Evaluation for Reinforced Concrete Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Rizwan">Muhammad Rizwan</a>, <a href="https://publications.waset.org/abstracts/search?q=Naveed%20Ahmad"> Naveed Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Akhtar%20Naeem%20Khan"> Akhtar Naeem Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Seismic behavior factors are evaluated for the performance assessment of low rise reinforced concrete RC frame structures based on experimental study of unidirectional dynamic shake table testing of two 1/3rd reduced scaled two storey frames, with a code confirming special moment resisting frame (SMRF) model and a noncompliant model of similar characteristics but built in low strength concrete .The models were subjected to a scaled accelerogram record of 1994 Northridge earthquake to deformed the test models to final collapse stage in order to obtain the structural response parameters.

The study aimed to determine the training needs of secondary school teachers on different aspects of knowledge & understanding component of instructional planning and strategies. The target population of the study was the secondary school teachers across Pakistan. For this purpose, a sample of 400 secondary school teachers was selected through multistage sampling from all the four provinces and Federal capital area. Survey method was adopted to assess the training needs by using a self reporting tool. The tool helped to gauge the training needs through indirect inventory questions as well as a ranking list in which the respondents themselves prioritized their training areas. The results showed variation between the direct and indirect reporting of the teachers on the basis of which it was concluded that the secondary school teachers needed awareness about the knowledge component of instructional planning and strategies in order to redefine their actual training needs. The researcher further identified the training needs of secondary school teachers within each province and Islamabad capital territory; including an analysis of variations between strata. As teachers are considered agents of change, their training according to the professional standards should provide a solid base for “rethinking education”. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=training%20needs" title="training needs">training needs</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20school%20teachers" title=" secondary school teachers"> secondary school teachers</a>, <a href="https://publications.waset.org/abstracts/search?q=instructional%20planning%20%26%20strategies" title=" instructional planning & strategies"> instructional planning & strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20%26%20understanding" title=" knowledge & understanding"> knowledge & understanding</a> </p> <a href="https://publications.waset.org/abstracts/158904/rethinking-training-needs-of-secondary-school-teachers-in-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158904.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">90</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Screening of Risk Phenotypes among Metabolic Syndrome Subjects in Adult Pakistani Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Fiaz">Muhammad Fiaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Saqlain"> Muhammad Saqlain</a>, <a href="https://publications.waset.org/abstracts/search?q=Abid%20Mahmood"> Abid Mahmood</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20M.%20Saqlan%20Naqvi"> S.

The tests were conducted on oxide films grown in saturated calcium hydroxide solutions that included different representative amounts of NaOH and KOH which are the compounds commonly observed in ordinary portland cement concrete pore solution. In addition to that, commonly used mineral admixtures (silica fume, natural pozzolan and fly ash) were also added to the simulated concrete pore solution. The results of electrochemical tests show that supplementary cementitious materials do have an effect on the protective properties of the passive oxide film. In particular, silica fume has been shown to have a negative influence on the film quality though it has positive effect on the concrete properties. Fly ash and natural pozzolan increase the protective qualities of the passive film. The research data in this area is very limited in the past and needed further investigation. <p class="card-text"><strong>Keywords:</strong> <a
