This paper presents an Enhanced Harmony Search (ENHS) algorithm for solving optimization problems. The proposed algorithm increases the convergence and is more efficient than the standard Harmony Search (HS) algorithm. The paper discusses the novel techniques in detail and also provides the strategy for tuning the decisive parameters that affects the efficiency of the ENHS algorithm. The algorithm is tested on various benchmark functions, a real world optimization problem and a constrained objective function. Also, the results of ENHS are compared to standard HS, and various other optimization algorithms. The ENHS algorithms prove to be significantly better and more efficient than other algorithms. The simulation and testing of the algorithms is performed in MATLAB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimization" title="optimization">optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=harmony%20search%20algorithm" title=" harmony search algorithm"> harmony search algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=MATLAB" title=" MATLAB"> MATLAB</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic" title=" electronic"> electronic</a> </p> <a href="https://publications.waset.org/abstracts/3244/an-enhanced-harmony-search-enhs-algorithm-for-solving-optimization-problems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3244.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">463</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">805</span> Type of Sun Trackers and Its Controlling Techniques for MPPT</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Talha%20Ali%20Khan">Talha Ali Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Discovering different energy resources to full fill the world growing demand is now one of the society’s bigger challenge for the next half-century.

The elimination of liquid-vapor phase change-based thermal and water management systems is being done due to issues with the reliability and robustness of this technology. To achieve the motive of implementing the principle of using an innovative evaporator and condenser design utilizing bimodal wicks manufactured using a microsecond pulsed CO₂ laser has been proposed in this study. Cylin drical, multilayered capillary copper wicks with a substrate diameter of 39 mm are additively manufactured using a pulsed laser. The copper particles used for layer-by-layer addition on the substrate measure in a diameter range of 225 to 450 micrometers. The primary objective is to develop a novel, high-quality, fast turnaround, laser-based additive manufacturing process that will eliminate the current technical challenges involved with the traditional manufacturing processes for nano/micro-sized powders, like particle agglomeration. Raster-scanned, pulsed-laser sintering process has been developed to manufacture 3D wicks with controlled porosity and permeability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=liquid-vapor%20phase%20change" title="liquid-vapor phase change">liquid-vapor phase change</a>, <a href="https://publications.waset.org/abstracts/search?q=bimodal%20wicks" title=" bimodal wicks"> bimodal wicks</a>, <a href="https://publications.waset.org/abstracts/search?q=multilayered" title=" multilayered"> multilayered</a>, <a href="https://publications.waset.org/abstracts/search?q=capillary" title=" capillary"> capillary</a>, <a href="https://publications.waset.org/abstracts/search?q=raster-scanned" title=" raster-scanned"> raster-scanned</a>, <a href="https://publications.waset.org/abstracts/search?q=porosity" title=" porosity"> porosity</a>, <a href="https://publications.waset.org/abstracts/search?q=permeability" title=" permeability"> permeability</a> </p> <a href="https://publications.waset.org/abstracts/140148/development-of-multilayer-capillary-copper-wick-structure-using-microsecond-co2-pulsed-laser" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140148.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">191</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">800</span> The Potential Factors Relating to the Decision of Return Migration of Myanmar Migrant Workers: A Case Study in Prachuap Khiri Khan Province</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Musthaya%20Patchanee">Musthaya Patchanee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this research is to study potential factors relating to the decision of return migration of Myanmar migrant workers in Prachuap Khiri Khan Province by conducting a random sampling of 400 people aged between 15-59 who migrated from Myanmar. The information collected through interviews was analyzed to find a percentage and mean using the Stepwise Multiple Regression Analysis. The results have shown that 33.25% of Myanmar migrant workers want to return to their home country within the next 1-5 years, 46.25%, in 6-10 years and the rest, in over 10 years. The factors relating to such decision can be concluded that the scale of the decision of return migration has a positive relationship with a statistical significance at 0.05 with a conformity with friends and relatives (r=0.886), a relationship with family and community (r=0.782), possession of land in hometown (r=0.756) and educational level (r=0.699). However, the factor of property possession in Prachuap Khiri Khan is the only factor with a high negative relationship (r=0.-537). From the Stepwise Multiple Regression Analysis, the results have shown that the conformity with friends and relatives and educational level factors are influential to the decision of return migration of Myanmar migrant workers in Prachuap Khiri Khan Province, which can predict the decision at 86.60% and the multiple regression equation from the analysis is Y= 6.744+1.198 conformity + 0.647 education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decision%20of%20return%20migration" title="decision of return migration">decision of return migration</a>, <a href="https://publications.waset.org/abstracts/search?q=factors%20of%20return%20migration" title=" factors of return migration"> factors of return migration</a>, <a href="https://publications.waset.org/abstracts/search?q=Myanmar%20migrant%20workers" title=" Myanmar migrant workers"> Myanmar migrant workers</a>, <a href="https://publications.waset.org/abstracts/search?q=Prachuap%20Khiri%20Khan%20Province" title=" Prachuap Khiri Khan Province"> Prachuap Khiri Khan Province</a> </p> <a href="https://publications.waset.org/abstracts/30208/the-potential-factors-relating-to-the-decision-of-return-migration-of-myanmar-migrant-workers-a-case-study-in-prachuap-khiri-khan-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30208.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">541</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">799</span> Application of Hydrologic Engineering Centers and River Analysis System Model for Hydrodynamic Analysis of Arial Khan River</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Najeeb%20Hassan">Najeeb Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmudur%20Rahman"> Mahmudur Rahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Arial Khan River is one of the main south-eastward outlets of the River Padma. This river maintains a meander channel through its course and is erosional in nature. The specific objective of the research is to study and evaluate the hydrological characteristics in the form of assessing changes of cross-sections, discharge, water level and velocity profile in different stations and to create a hydrodynamic model of the Arial Khan River. Necessary data have been collected from Bangladesh Water Development Board (BWDB) and Center for Environment and Geographic Information Services (CEGIS). Satellite images have been observed from Google earth. In this study, hydrodynamic model of Arial Khan River has been developed using well known steady open channel flow code Hydrologic Engineering Centers and River Analysis System (HEC-RAS) using field surveyed geometric data. Cross-section properties at 22 locations of River Arial Khan for the years 2011, 2013 and 2015 were also analysed. 1-D HEC-RAS model has been developed using the cross sectional data of 2015 and appropriate boundary condition is being used to run the model. This Arial Khan River model is calibrated using the pick discharge of 2015. The applicable value of Mannings roughness coefficient (n) is adjusted through the process of calibration. The value of water level which ties with the observed data to an acceptable accuracy is taken as calibrated model. The 1-D HEC-RAS model then validated by using the pick discharges from 2009-2018. Variation in observed water level in the model and collected water level data is being compared to validate the model. It is observed that due to seasonal variation, discharge of the river changes rapidly and Mannings roughness coefficient (n) also changes due to the vegetation growth along the river banks. This river model may act as a tool to measure flood area in future. By considering the past pick flow discharge, it is strongly recommended to improve the carrying capacity of Arial Khan River to protect the surrounding areas from flash flood. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BWDB" title="BWDB">BWDB</a>, <a href="https://publications.waset.org/abstracts/search?q=CEGIS" title=" CEGIS"> CEGIS</a>, <a href="https://publications.waset.org/abstracts/search?q=HEC-RAS" title=" HEC-RAS"> HEC-RAS</a> </p> <a href="https://publications.waset.org/abstracts/119282/application-of-hydrologic-engineering-centers-and-river-analysis-system-model-for-hydrodynamic-analysis-of-arial-khan-river" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119282.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">798</span> Library Anxiety among Library and Information Science Students at Khushal Khan Khattak University Karak, Pakistan: A Bostick Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Ullah%20Jan">Saeed Ullah Jan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shafaq"> Shafaq</a>, <a href="https://publications.waset.org/abstracts/search?q=Sumbul"> Sumbul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Anxiety is one of the most common emotions and is a normal reaction to danger or a threat.

Special training needs to be arranged for female students to improve their library usage and readership rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=library-anxiety" title="library-anxiety">library-anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=library%20anxiety-students" title=" library anxiety-students"> library anxiety-students</a>, <a href="https://publications.waset.org/abstracts/search?q=library%20anxiety%20-students-Pakistan" title=" library anxiety -students-Pakistan"> library anxiety -students-Pakistan</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a> </p> <a href="https://publications.waset.org/abstracts/144309/library-anxiety-among-library-and-information-science-students-at-khushal-khan-khattak-university-karak-pakistan-a-bostick-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144309.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">192</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">797</span> Comparision of Statistical Variables for Vaccinated and Unvaccinated Children in Measles Cases in Khyber Pukhtun Khwa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Inayatullah%20Khan">Inayatullah Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Afzal%20Khan"> Afzal Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamzullah%20Khan"> Hamzullah Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Afzal%20Khan"> Afzal Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: The objective of this study was to compare different statistical variables for vaccinated and unvaccinated children in measles cases. Material and Methods: This cross sectional comparative study was conducted at Isolation ward, Department of Paediatrics, Lady Reading Hospital (LRH), Peshawar, from April 2012 to March 2013. A total of 566 admitted cases of measles were enrolled. Data regarding age, sex, address, vaccination status, measles contact, hospital stay and outcome was collected and recorded on a proforma. History of measles vaccination was ascertained either by checking the vaccination cards or on parental recall. Result: In 566 cases of measles, 211(39%) were vaccinated and 345 (61%) were unvaccinated. Three hundred and ten (54.80%) patients were males and 256 (45.20%) were females with a male to female ratio of 1.2:1.The age range was from 1 year to 14 years with mean age with SD of 3.2 +2 years. Majority (371, 65.5%) of the patients were 1-3 years old. Mean hospital stay was 3.08 days with a range of 1-10 days and a standard deviation of ± 1.15. History of measles contact was present in 393 (69.4%) cases. Fourty eight patients were expired with a mortality rate of 8.5%. Conclusion: Majority of the children in Khyber Pukhtunkhwa are unvaccinated and unprotected against measles. Among vaccinated children, 39% of children attracted measles which indicate measles vaccine failure. This figure is clearly higher than that accepted for measles vaccine (2-10%). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=measles" title="measles">measles</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccination" title=" vaccination"> vaccination</a>, <a href="https://publications.waset.org/abstracts/search?q=immunity" title=" immunity"> immunity</a>, <a href="https://publications.waset.org/abstracts/search?q=population" title=" population"> population</a> </p> <a href="https://publications.waset.org/abstracts/12615/comparision-of-statistical-variables-for-vaccinated-and-unvaccinated-children-in-measles-cases-in-khyber-pukhtun-khwa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12615.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">444</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">796</span> Green It-Outsourcing Assurance Model for It-Outsourcing Vendors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siffat%20%20Ullah%20Khan">Siffat Ullah Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahmat%20Ullah%20Khan"> Rahmat Ullah Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafiq%20%20Ahmad%20Khan"> Rafiq Ahmad Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Habibullah%20Khan"> Habibullah Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Green IT or green computing has emerged as a fast growing business paradigm in recent years in order to develop energy-efficient Software and peripheral devices. With the constant evolution of technology and the world critical environmental status, all private and public information technology (IT) businesses are moving towards sustainability. We identified, through systematic literature review and questionnaire survey, 9 motivators, in total, faced by vendors in IT-Outsourcing relationship. Amongst these motivators 7 were ranked as critical motivators. We also identified 21, in total, practices for addressing these critical motivators. Based on these inputs we have developed Green IT-Outsourcing Assurance Model (GITAM) for IT-Outsourcing vendors. The model comprises four different levels. i.e. Initial, White, Green and Grey. Each level comprises different critical motivators and their relevant practices. We conclude that our model, GITAM, will assist IT-Outsourcing vendors in gauging their level in order to manage IT-Outsourcing activities in a green and sustainable fashion to assist the environment and to reduce the carbon emission. The model will assist vendors in improving their current level by suggesting various practices. The model will contribute to the body of knowledge in the field of Green IT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Green%20IT-outsourcing%20Assurance%20Model%20%28GITAM%29" title="Green IT-outsourcing Assurance Model (GITAM)">Green IT-outsourcing Assurance Model (GITAM)</a>, <a href="https://publications.waset.org/abstracts/search?q=Systematic%20Literature%20Review" title=" Systematic Literature Review"> Systematic Literature Review</a>, <a href="https://publications.waset.org/abstracts/search?q=Empirical%20Study" title=" Empirical Study"> Empirical Study</a>, <a href="https://publications.waset.org/abstracts/search?q=Case%20Study" title=" Case Study"> Case Study</a> </p> <a href="https://publications.waset.org/abstracts/132174/green-it-outsourcing-assurance-model-for-it-outsourcing-vendors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132174.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">252</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">795</span> Scar Removal Stretegy for Fingerprint Using Diffusion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20A.%20U.%20Khan">Mohammad A.

Blended learning is an education programme that combines online digital media with traditional classroom methods. It requires the physical presence of both lecturer and student in a mathematics computer laboratory. Blended learning provides element of class control over time, place, path or pace. The focus was on the use of Khan Academy to supplement traditional classroom interactions. Khan Academy is a non-profit educational organisation created by educator Salman Khan with a goal of creating an accessible place for students to learn through watching videos in a computer assisted computer. The researcher who is an also lecturer in mathematics support programme collected data through instructing students to watch Khan Academy videos on radian measures, and by supplying students with traditional classroom activities. Classroom activities entails radian measure activities extracted from the Internet. Students were given an opportunity to engage in class discussions, social interactions and collaborations. These activities necessitated students to write formative assessments tests. The purpose of formative assessments tests was to find out about the students’ understanding of radian measures, including errors and misconceptions they displayed in their calculations. Identification of errors and misconceptions serve as pointers of students’ weaknesses and strengths in their learning of radian measures. At the end of data collection, semi-structure interviews were administered to a purposefully sampled group to explore their perceptions and feedback regarding the use of blended learning approach in teaching and learning of radian measures. The study employed Algebraic Insight Framework to analyse data collected. Algebraic Insight Framework is a subset of symbol sense which allows a student to correctly enter expressions into a computer assisted systems efficiently. This study offers students opportunities to enter topics and subtopics on radian measures into a computer through the lens of Khan Academy. Khan academy demonstrates procedures followed to reach solutions of mathematical problems. The researcher performed the task of explaining mathematical concepts and facilitated the process of reinvention of rules and formulae in the learning of radian measures. Lastly, activities that reinforce students’ understanding of radian were distributed. Results showed that this study enthused the students in their learning of radian measures. Learning through videos prompted the students to ask questions which brought about clarity and sense making to the classroom discussions. Data revealed that sense making through reinvention of rules and formulae assisted the students in enhancing their learning of radian measures. This study recommends the use of Khan Academy in blended learning to be introduced as a socialisation programme to all first year students. This will prepare students that are computer illiterate to become conversant with the use of Khan Academy as a powerful tool in the learning of mathematics. Khan Academy is a key technological tool that is pivotal for the development of students’ autonomy in the learning of mathematics and that promotes collaboration with lecturers and peers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=algebraic%20insight%20framework" title="algebraic insight framework">algebraic insight framework</a>, <a href="https://publications.waset.org/abstracts/search?q=blended%20learning" title=" blended learning"> blended learning</a>, <a href="https://publications.waset.org/abstracts/search?q=Khan%20Academy" title=" Khan Academy"> Khan Academy</a>, <a href="https://publications.waset.org/abstracts/search?q=radian%20measures" title=" radian measures "> radian measures </a> </p> <a href="https://publications.waset.org/abstracts/70918/blended-learning-in-a-mathematics-classroom-a-focus-in-khan-academy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70918.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">310</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">793</span> Prediction Fluid Properties of Iranian Oil Field with Using of Radial Based Neural Network </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Memari">Abdolreza Memari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article in order to estimate the viscosity of crude oil,a numerical method has been used. We use this method to measure the crude oil's viscosity for 3 states: Saturated oil's viscosity, viscosity above the bubble point and viscosity under the saturation pressure. Then the crude oil's viscosity is estimated by using KHAN model and roller ball method. After that using these data that include efficient conditions in measuring viscosity, the estimated viscosity by the presented method, a radial based neural method, is taught. This network is a kind of two layered artificial neural network that its stimulation function of hidden layer is Gaussian function and teaching algorithms are used to teach them. After teaching radial based neural network, results of experimental method and artificial intelligence are compared all together. Teaching this network, we are able to estimate crude oil's viscosity without using KHAN model and experimental conditions and under any other condition with acceptable accuracy. Results show that radial neural network has high capability of estimating crude oil saving in time and cost is another advantage of this investigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=viscosity" title="viscosity">viscosity</a>, <a href="https://publications.waset.org/abstracts/search?q=Iranian%20crude%20oil" title=" Iranian crude oil"> Iranian crude oil</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20based" title=" radial based"> radial based</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title=" neural network"> neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=roller%20ball%20method" title=" roller ball method"> roller ball method</a>, <a href="https://publications.waset.org/abstracts/search?q=KHAN%20model" title=" KHAN model "> KHAN model </a> </p> <a href="https://publications.waset.org/abstracts/29815/prediction-fluid-properties-of-iranian-oil-field-with-using-of-radial-based-neural-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29815.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">501</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">792</span> Automated Heart Sound Classification from Unsegmented Phonocardiogram Signals Using Time Frequency Features</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Masood%20Khan">Nadia Masood Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Salman%20Khan"> Muhammad Salman Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Gul%20Muhammad%20Khan"> Gul Muhammad Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cardiologists perform cardiac auscultation to detect abnormalities in heart sounds. Since accurate auscultation is a crucial first step in screening patients with heart diseases, there is a need to develop computer-aided detection/diagnosis (CAD) systems to assist cardiologists in interpreting heart sounds and provide second opinions. In this paper different algorithms are implemented for automated heart sound classification using unsegmented phonocardiogram (PCG) signals. Support vector machine (SVM), artificial neural network (ANN) and cartesian genetic programming evolved artificial neural network (CGPANN) without the application of any segmentation algorithm has been explored in this study. The signals are first pre-processed to remove any unwanted frequencies. Both time and frequency domain features are then extracted for training the different models. The different algorithms are tested in multiple scenarios and their strengths and weaknesses are discussed. Results indicate that SVM outperforms the rest with an accuracy of 73.64%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pattern%20recognition" title="pattern recognition">pattern recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20aided%20diagnosis" title="computer aided diagnosis">computer aided diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20sound%20classification" title=" heart sound classification"> heart sound classification</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20feature%20extraction" title=" and feature extraction"> and feature extraction</a> </p> <a href="https://publications.waset.org/abstracts/95434/automated-heart-sound-classification-from-unsegmented-phonocardiogram-signals-using-time-frequency-features" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95434.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">263</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">791</span> A Modified Shannon Entropy Measure for Improved Image Segmentation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20A.%20U.%20Khan">Mohammad A.

One of the key components of the programme is the professional development of teachers, headteachers and teacher educators through a variety of teacher education programmes including a two-year Masters of Education (MEd) Programme offered by AKU-IED. A number of teachers, headteachers and teacher educators from these provinces have been developed through the MEd Programme. This paper discusses a qualitative research study conducted to explore the nature, relevance, rigor and richness of the experiences of the MEd graduates, and how these experiences have fostered their own professional development and their ability to bring about positive changes in their schools. The findings of the study provide useful insights into the graduates’ self-actualization, the transformation of their professional beliefs and practices, the difference they have made in their schools, and the challenges they face. The study also provides recommendations for policy and practice related to teacher education programmes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=STEP" title="STEP">STEP</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20education" title=" teacher education"> teacher education</a>, <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title=" Pakistan"> Pakistan</a>, <a href="https://publications.waset.org/abstracts/search?q=Canada" title=" Canada"> Canada</a>, <a href="https://publications.waset.org/abstracts/search?q=Aga%20Khan%20foundation" title=" Aga Khan foundation"> Aga Khan foundation</a> </p> <a href="https://publications.waset.org/abstracts/43725/developing-teachers-as-change-agents-a-qualitative-study-of-master-of-education-graduates-in-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43725.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">348</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">789</span> Controlled Size Synthesis of ZnO and PEG-ZnO NPs and Their Biological Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahnoor%20Khan">Mahnoor Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bashir%20Ahmad"> Bashir Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Khizar%20Hayat"> Khizar Hayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Saad%20Ahmad%20Khan"> Saad Ahmad Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Laiba%20Ahmad"> Laiba Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Shumaila%20Bashir"> Shumaila Bashir</a>, <a href="https://publications.waset.org/abstracts/search?q=Abid%20Ali%20Khan"> Abid Ali Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study was to synthesize the smallest possible size of ZnO NPs using a modified wet chemical synthesis method and to prepare core shell using polyethylene glycol (PEG) as shell material. 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">788</span> Integrated Water Resources Management to Ensure Water Security of Arial Khan River Catchment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abul%20Kalam%20Azad">Abul Kalam Azad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water security has become an increasingly important issue both at the national and international levels.

The elements of water security such as sectoral demands of water, conflicting requirements amongst the sectors, balancing between demand and supply including the quality of water can best be understood and managed in a catchment as it is the standard functioning unit. The Arial Khan River catchment consists of parts of Faridpur, Madaripur, Shariatpur and Barishal districts have all the components of water demands such as agriculture, domestic, commercial, industrial, forestry, fisheries, navigation or recreation and e-flow requirements. Based on secondary and primary data, water demands of various sectors have been determined. CROPWAT 8.0 has been used to determine the Agricultural Water Demand. Mean Annual Flow (MAF) and Flow Duration Curve (FDC) have been used to determine the e-flow requirements. Water Evaluation and Planning System (WEAP) based decision support tool as part of Integrated Water Resources Management (IWRM) has been utilized for ensuring the water security of the Arial Khan River catchment. Studies and practice around the globe connected with water security were consulted to mitigate the pressure on demand and supply including the options available to ensure the water security. Combining all the information, a framework for ensuring water security has been suggested for Arial Khan River catchment which can further be projected to river basin as well as for the country. This will assist planners and researchers to introduce the model for integrated water resources management of any catchment/river basins. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20security" title="water security">water security</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20demand" title=" water demand"> water demand</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20supply" title=" water supply"> water supply</a>, <a href="https://publications.waset.org/abstracts/search?q=WEAP" title=" WEAP"> WEAP</a>, <a href="https://publications.waset.org/abstracts/search?q=CROPWAT" title=" CROPWAT"> CROPWAT</a> </p> <a href="https://publications.waset.org/abstracts/191697/integrated-water-resources-management-to-ensure-water-security-of-arial-khan-river-catchment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191697.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">20</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">787</span> Fabrication of ZnO Nanorods Based Biosensor via Hydrothermal Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Tariq">Muhammad Tariq</a>, <a href="https://publications.waset.org/abstracts/search?q=Jafar%20Khan%20Kasi"> Jafar Khan Kasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Samiullah"> Samiullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Ajab%20Khan%20Kasi"> Ajab Khan Kasi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biosensors are playing vital role in industrial, clinical, and chemical analysis applications. Among other techniques, ZnO based biosensor is an easy approach due to its exceptional chemical and electrical properties. ZnO nanorods have positively charged isoelectric point which helps immobilize the negative charge glucose oxides (GOx). Here, we report ZnO nanorods based biosensors for the immobilization of GOx. The ZnO nanorods were grown by hydrothermal method on indium tin oxide substrate (ITO). The fabrication of biosensors was carried through batch processing using conventional photolithography. The buffer solutions of GOx were prepared in phosphate with a pH value of around 7.3. The biosensors effectively immobilized the GOx and result was analyzed by calculation of voltage and current on nanostructures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrothermal%20growth" title="hydrothermal growth">hydrothermal growth</a>, <a href="https://publications.waset.org/abstracts/search?q=sol-gel" title=" sol-gel"> sol-gel</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc%20dioxide" title=" zinc dioxide"> zinc dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=biosensors" title=" biosensors"> biosensors</a> </p> <a href="https://publications.waset.org/abstracts/97617/fabrication-of-zno-nanorods-based-biosensor-via-hydrothermal-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97617.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">301</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">786</span> An Overview of Thermal Storage Techniques for Solar Thermal Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Talha%20Shafiq">Talha Shafiq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The traditional electricity operation in solar thermal plants is designed to operate on a single path initiating at power plant and executes at the consumer.

In this study, it is tried to show that political Talk shows broadcast by Private TV channels are working apparatuses of ideology and store meanings which are not always obvious for readers. This analysis was about the situation created by Arslan Iftkhar, the son of ex-Chief Justice of Pakistan, Iftikhar Muhammad Chaudry and PTI Chief Imran Khan. Arslan Iftikhar submitted an application against Imran Khan that he is not able to become a member of parliament of Pakistan. In the application, he demanded the documents, which are submitted by Imran Khan at the time of Election to the Election Commission of Pakistan. Murad Ali from PTI also submitted an application against PM Nawaz Sharif to the Election Commission of Pakistan for providing the copies. It also suggests that these talk shows mystify the agency of processes by using various strategies. In other words, critical text analyses reveal how these choices enable speakers to manipulate the realizations of agency and power in the representation of action to produce particular meanings which are not always explicit for all readers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ECP" title="ECP">ECP</a>, <a href="https://publications.waset.org/abstracts/search?q=CDA" title=" CDA"> CDA</a>, <a href="https://publications.waset.org/abstracts/search?q=socio%20cognitive%20model" title=" socio cognitive model"> socio cognitive model</a>, <a href="https://publications.waset.org/abstracts/search?q=ideology" title=" ideology"> ideology</a>, <a href="https://publications.waset.org/abstracts/search?q=TV%20channels" title=" TV channels"> TV channels</a>, <a href="https://publications.waset.org/abstracts/search?q=power" title=" power"> power</a> </p> <a href="https://publications.waset.org/abstracts/17046/critical-discourse-analysis-of-political-tv-talk-show-of-pakistani-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17046.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">738</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">782</span> Experimental Lead Toxicity in Lohi Sheep: Risks and Impact on Edible Tissues</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Younus">Muhammad Younus</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Sajid"> Muhammad Sajid</a>, <a href="https://publications.waset.org/abstracts/search?q=Muti-ur-Rehman%20Khan"> Muti-ur-Rehman Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Aftab%20Ahmad%20Anjum"> Aftab Ahmad Anjum</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Asif%20Idrees"> Muhammad Asif Idrees</a>, <a href="https://publications.waset.org/abstracts/search?q=Iahtasham%20Khan"> Iahtasham Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Aman%20Ullah%20Khan"> Aman Ullah Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajid%20Umar"> Sajid Umar</a>, <a href="https://publications.waset.org/abstracts/search?q=Raheela%20Akhtar"> Raheela Akhtar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study was conducted to investigate the hazardous effects of lead on health and edible organs of Lohi sheep. The adult Lohi sheep (n=48) were randomly divided into two equal groups. The first group was administered lead acetate at dose of 70 mg/kg live body weight daily as 10% solution by oral route for a period of 90 days and the second group served as a negative control. Blood and tissue samples were collected at day 0, 30, 60 and 90 and analyzed for lead concentration by atomic absorption spectrophotometry. The kidney showed the highest lead concentration (p < 0.05) followed by liver and then muscle. Lead acetate treated sheep showed structural and behavioral changes during the last month of trial. Liver showed necrosis, hemorrhages and hyperactivation of macrophages. Kidney showed degenerative and necrotic changes in glomeruli and tubules and the characteristic intranuclear inclusion bodies in tubular epithelial cells on H and E staining. It was concluded that Lohi sheep is affected by lead intoxication at low dose for longer period and hence exhibits lead accumulation in edible tissues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lohi%20sheep" title="Lohi sheep">Lohi sheep</a>, <a href="https://publications.waset.org/abstracts/search?q=lead%20acetate" title=" lead acetate"> lead acetate</a>, <a href="https://publications.waset.org/abstracts/search?q=edible%20tissue" title=" edible tissue"> edible tissue</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathology" title=" histopathology"> histopathology</a> </p> <a href="https://publications.waset.org/abstracts/68559/experimental-lead-toxicity-in-lohi-sheep-risks-and-impact-on-edible-tissues" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68559.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">781</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.

Tungsten carbide has been extensively used as tool insert for machining processes involving chip removal processes. These hard materials are generally fabricated by single step sintering process as further modification after fabrication in these materials cannot be done easily. Advances in tool surface modification have revealed that advantages such as improved tribological properties and extended tool life can be harnessed from the same tool by texturing the tool rake surface. Moreover, it has been observed that the shape and location of the texture also influences the behavior. Although texturing offers plentiful advantages the challenge lies in the generation of textures on the tool surface. Extremely hard material such as diamond is required to process tungsten carbide. Laser is unique processing tool that does not have a physical contact with the material and thus does not wear. In this research the potential of utilizing laser for texturing of tungsten carbide to develop custom features would be studied. A parametric study of texturing of Tungsten Carbide with a femtosecond laser would be conducted to investigate the process parameters and establish the feasible processing window. The effect of fluence, scan speed and number of repetition would be viewed in detail. Moreover, the mechanism for the generation of features would also be reviewed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laser" title="laser">laser</a>, <a href="https://publications.waset.org/abstracts/search?q=texturing" title=" texturing"> texturing</a>, <a href="https://publications.waset.org/abstracts/search?q=femtosecond" title=" femtosecond"> femtosecond</a>, <a href="https://publications.waset.org/abstracts/search?q=tungsten%20carbide" title=" tungsten carbide"> tungsten carbide</a> </p> <a href="https://publications.waset.org/abstracts/34276/texturing-of-tool-insert-using-femtosecond-laser" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34276.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">658</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">777</span> Incidence of Post Endoscopic Retrograde Cholangiopancreatography Biliary Ascariasis Diagnosed on Ultrasound</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shehzad%20Khan">Shehzad Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Jehangir%20Khan"> Jehangir Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shah%20Babar"> Shah Babar</a>, <a href="https://publications.waset.org/abstracts/search?q=Rashid%20Mahmood"> Rashid Mahmood</a>, <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Khan"> Rizwan Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanya%20Hadi"> Sanya Hadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ascaris lumbricoides are familiar with the roundworm that causes biliary infections in humans. Nevertheless, ascariasis is primarily found in the jejunum and transferred in numerous body parts with the intake of Ascaris lumbricoides present in food and water. These study methods were implemented at the Saidu Teaching Hospital Radiology Department from December 2021 to January 2023. This study includes the participants suffering from biliary ascariasis admitted or visited Saidu Teaching Hospital in that time frame. Clinical assessment of the participants was done based on the appearance of signs and symptoms present in them. The participant's laboratory test was done to determine the level of basic body parameters. After that ultrasonography was used to diagnose the presence and appearance of worms. Endoscopic retrograde cholangiopancreatography (ERCP) was used to extract worms from biliary channels, and the incidence of post-ERCP biliary ascariasis was accessed with ultrasonography. This study's results show the presence of numerous types of worms in the biliary channels of patients. Also, the level of body parameters, for instance, neutrophil, hemoglobin, and others, were compared at the time of admission and at the time of discharge from the hospital. Furthermore, the incidence of post-ERCP biliary ascariasis was reported as 4% in females, and 1% in males, respectively. <p class="card-text"><strong>Keywords:</strong> <a
