applications, there is an increased interest in machine learning techniques that can provide useful and interesting services in the smart home domain. The areas that machine learning techniques can help advance are varied and ever-evolving. Classifying smart home inhabitants’ Activities of Daily Living (ADLs), is one prominent example. The ability of machine learning technique to find meaningful spatio-temporal relations of high-dimensional data is an important requirement as well. This paper presents a comparative evaluation of state-of-the-art machine learning techniques to classify ADLs in the smart home domain. Forty-two synthetic datasets and two real-world datasets with multiple inhabitants are used to evaluate and compare the performance of the identified machine learning techniques. Our results show significant performance differences between the evaluated techniques. Such as AdaBoost, Cortical Learning Algorithm (CLA), Decision Trees, Hidden Markov Model (HMM), Multi-layer Perceptron (MLP), Structured Perceptron and Support Vector Machines (SVM). Overall, neural network based techniques have shown superiority over the other tested techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activities%20of%20daily%20living" title="activities of daily living">activities of daily living</a>, <a href="https://publications.waset.org/abstracts/search?q=classification" title=" classification"> classification</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things" title=" internet of things"> internet of things</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=prediction" title=" prediction"> prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20home" title=" smart home"> smart home</a> </p> <a href="https://publications.waset.org/abstracts/85195/evaluating-machine-learning-techniques-for-activity-classification-in-smart-home-environments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85195.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">357</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">54</span> Evaluation of Antimicrobial Activity of Phenolic Compounds Extracted from Jordanian Juglans regia L.</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamoud%20Alshammari">Hamoud Alshammari</a>, <a href="https://publications.waset.org/abstracts/search?q=Adnan%20Almezani"> Adnan Almezani</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamdan%20Alshammari"> Hamdan Alshammari</a>, <a href="https://publications.waset.org/abstracts/search?q=Faris%20Alharbi"> Faris Alharbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study we have examined of antimicrobial activity for unripe Juglan Regia phenolic extracts against a wide range of pathogenic microorganisms.

Acoustic emission (AE) and vibration analysis are some of the most accomplished techniques used for this purpose. Acoustic emission has the ability to detect the initial phase of component degradation. Moreover, it has been observed that the success of vibration analysis does not take place below 100 rpm rotational speed. This because the energy generated below 100 rpm rotational speed is not detectable using conventional vibration. From this pint, this paper has presented a focused review of using acoustic emission techniques for monitoring bearings condition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=condition%20monitoring" title="condition monitoring">condition monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20wave%20analysis" title=" stress wave analysis"> stress wave analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=low-speed%20bearings" title=" low-speed bearings"> low-speed bearings</a>, <a href="https://publications.waset.org/abstracts/search?q=bearing%20defect%20diagnosis" title=" bearing defect diagnosis"> bearing defect diagnosis</a> </p> <a href="https://publications.waset.org/abstracts/40780/bearing-condition-monitoring-with-acoustic-emission-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40780.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">315</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> The Job of Rhetoric in Public Relations Practice </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Talal%20Alqahtani">Talal Alqahtani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For all institutions, either public or private, communication is important now more than ever. This is because the importance of communication has grown over the years, and it has the ability to either break or make an organization. With globalization, the changing technology, and other emergent issues that affect organizations, the communication given out has had to be better, sharper, and both proactive and reactive. This is the reason why the importance of public relations has been on the increase. Institutions realize the importance of having a good image and having public relations experts who can effectively manage communication in an institution easily in times of crisis. Public relations itself is not, however, effective, and this has led to the adoption of rhetoric in communication. Rhetoric use has had a long transformation because, in the past, it was only used in politics. Rhetoric in communication has come to be appreciated and adopted by many diverse fields and sectors. This study looks at the job of rhetoric in public relations practice and how it can identify with the administration of an institution's notoriety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=communication" title="communication">communication</a>, <a href="https://publications.waset.org/abstracts/search?q=notoriety" title=" notoriety"> notoriety</a>, <a href="https://publications.waset.org/abstracts/search?q=rhetoric" title=" rhetoric"> rhetoric</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20relation" title=" public relation "> public relation </a> </p> <a href="https://publications.waset.org/abstracts/127134/the-job-of-rhetoric-in-public-relations-practice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127134.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">234</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">47</span> A Method to Saturation Modeling of Synchronous Machines in d-q Axes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Arbi%20Khlifi">Mohamed Arbi Khlifi</a>, <a href="https://publications.waset.org/abstracts/search?q=Badr%20M.%20Alshammari"> Badr M.

For that purpose, distinct methods of saturation modeling of dumper synchronous machine with cross-saturation are identified, and detailed models synthesis in d-q axes. A number of models are given in the final developed form. The procedure and the novel models are verified by a critical application to prove the validity of the method and the equivalence between all developed models is reported.

The findings show that coverage of diversity-related content in LIS graduate curricula is increasing at a slow but significant rate, and is often a low priority. Apart from LIS graduate courses for future librarians and information professionals in public libraries, school libraries, and museums providing services to young adults and children, there is not enough interest in the provision of services to diverse communities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diversity" title="diversity">diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=multiculturalism" title=" multiculturalism"> multiculturalism</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusion" title=" inclusion"> inclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=equality" title=" equality"> equality</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a> </p> <a href="https://publications.waset.org/abstracts/113740/diversity-strands-in-library-and-information-science-graduate-curricula" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113740.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">148</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> Laminar Burning Velocity NH₃/H₂+Air Mixtures at Elevated Temperatures and Pressures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Talal%20Hasan">Talal Hasan</a>, <a href="https://publications.waset.org/abstracts/search?q=Akram%20Mohammad"> Akram Mohammad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbon-free combustion has great attention in today’s research for its unlimited benefits regarding various factors, and ammonia is considered a potential carbon-free alternative gas despite its flame characteristics. The Shrestha mechanism and Chemkin-Pro software will be used for numerical data. Firstly, experimental and numerical results should show good agreement to move for studying the laminar flame speed of ammonia under various conditions. Ammonia flame speed will be investigated under normal conditions (298 K, 1 atm) as well as under the influence of a range of equivalence ratios (0.6-1.8), elevated temperatures (298,323,373,423, and 473), elevated pressures (1 atm- 70 atm) and finally at varying hydrogen content (0-100%). Therefore, this work will understand the ammonia laminar flame speed characteristics and how and to what extent hydrogen can improve ammonia combustion intensity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laminar%20burning%20velocity" title="laminar burning velocity">laminar burning velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=ammonia" title=" ammonia"> ammonia</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title=" hydrogen"> hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=combustion" title=" combustion"> combustion</a> </p> <a href="https://publications.waset.org/abstracts/166246/laminar-burning-velocity-nh3h2air-mixtures-at-elevated-temperatures-and-pressures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166246.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">107</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> Improved Artificial Bee Colony Algorithm for Non-Convex Economic Power Dispatch Problem </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Badr%20M.%20Alshammari">Badr M.

This paper proposes two methods of maximum power point tracking algorithm for photovoltaic systems, based on the first hand on P&O control and the other hand on the first order IC. The MPPT system ensures that solar cells can deliver the maximum power possible to the load. Different algorithms are used to design it. Here we compare them and simulate the photovoltaic system with two algorithms. The algorithms are used to control the duty cycle of a DC-DC converter in order to boost the output voltage of the PV generator and guarantee the operation of the solar panels in the Maximum Power Point (MPP).

Early detection of these defects is essential as it helps to avoid major failures and the associated catastrophic consequences. Signal processing techniques are required for early defect detection – in this article, a time domain technique called the Energy Index (EI) is used. This article presents an investigation into the Energy Index’s effectiveness to detect early-stage defect initiation and deterioration, and compares it with the common r.m.s. index, Kurtosis, and the Kolmogorov-Smirnov statistical test.

In this article, the reduction of 4-nitrophenol with NaBH4 has been used as a model reaction to investigate the catalytic activity of synthesized Au/NiO catalysts. In addition, we report a systematic study of the reduction kinetics and the influence of specific reaction parameters such as (i) temperature, (ii) stirring rate, (iii) sodium borohydride concentration and (iv) substrate/metal molar ratio. The reaction has been performed at a substrate/metal molar ratio of 7.4, a ratio significantly higher than previously reported. The reusability of the catalyst has been examined, with little to no decrease in activity observed over 5 catalytic cycles. Systematic variation of Au loading reveals the successful synthesis of low-cost and efficient Au/NiO catalysts at very low Au content and using high substrate/metal molar ratios. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonochemistry" title="nonochemistry">nonochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=catalyst" title=" catalyst"> catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticles%20supported" title=" nanoparticles supported"> nanoparticles supported</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization%20of%20materials" title=" characterization of materials"> characterization of materials</a>, <a href="https://publications.waset.org/abstracts/search?q=colloidal%20nanoparticles" title=" colloidal nanoparticles"> colloidal nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/184004/preformed-au-colloidal-nanoparticles-immobilised-on-nio-as-highly-efficient-heterogeneous-catalysts-for-reduction-of-4-nitrophenol-to-4-aminophenol" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184004.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">65</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> BigCrypt: A Probable Approach of Big Data Encryption to Protect Personal and Business Privacy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20Al%20Mamun">Abdullah Al Mamun</a>, <a href="https://publications.waset.org/abstracts/search?q=Talal%20Alkharobi"> Talal Alkharobi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As data size is growing up, people are became more familiar to store big amount of secret information into cloud storage. Companies are always required to need transfer massive business files from one end to another. We are going to lose privacy if we transmit it as it is and continuing same scenario repeatedly without securing the communication mechanism means proper encryption. Although asymmetric key encryption solves the main problem of symmetric key encryption but it can only encrypt limited size of data which is inapplicable for large data encryption. In this paper we propose a probable approach of pretty good privacy for encrypt big data using both symmetric and asymmetric keys. Our goal is to achieve encrypt huge collection information and transmit it through a secure communication channel for committing the business and personal privacy.

The main advantages of air drilling include the higher rate of penetration, less formation damage, lower risk of loss of circulation. However, these advantages cannot be fully realized if thermal effects in air drilling are not well understood and minimized. Due to its high frictional coefficient, low heat conductivity, and high compressibility, air can impact the temperature distribution of bit and thus affect its bit performances. Based on energy and mass balances, a transient thermal model that predicts bit temperature is presented along with numerical solutions in this paper. In addition, several important parameters that influence bit temperature distribution are analyzed. Simulation results show that the bit temperature increases with increasing weight on bit and rotary speed but decreases as the standpipe pressure and flow rate increase. These results can be used to optimize drilling operations and flow parameters for an improved bit performance as shown in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20drilling" title="air drilling">air drilling</a>, <a href="https://publications.waset.org/abstracts/search?q=rate%20of%20penetration" title=" rate of penetration"> rate of penetration</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=rotary%20speed" title=" rotary speed"> rotary speed</a> </p> <a href="https://publications.waset.org/abstracts/65147/thermodynamically-predicting-the-impact-of-temperature-on-the-performance-of-drilling-bits-as-a-function-of-time" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65147.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">285</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> Optimal Design of Multimachine Power System Stabilizers Using Improved Multi-Objective Particle Swarm Optimization Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Badr%20M.%20Alshammari">Badr M.

A composite set of objective functions comprising the damping factor and the damping ratio of the undamped and lightly damped electromechanical modes is considered. The performance of the proposed optimization algorithm is verified for the 3-machine 9-bus system.

The soil behaviour is assumed to be elastic with Rayleigh damping, while the micropiles are modeled as 3D elastic beam elements. The bridge deck slab was represented by a concentrated mass at the top of the pier column. The interaction between the added micropiles and the existing piles as well as the performance of the retrofitted soil-pile-superstructure system were investigated for different configurations of additional micropiles (number, position, inclination). Numerical simulation results show that additional micropiles constitute an efficient retrofitting solution. Analysis of results also shows that spacing between existing piles and retrofitting micropiles has little effect; while it is observed a substantial improvement (in case of weak piles/micropiles - soil interface) with reducing the inclination angle of retrofitting micropiles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=retrofitting" title="retrofitting">retrofitting</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element" title=" finite element"> finite element</a>, <a href="https://publications.waset.org/abstracts/search?q=micropiles" title=" micropiles"> micropiles</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic" title=" elastic"> elastic</a> </p> <a href="https://publications.waset.org/abstracts/109238/seismic-retrofit-of-existing-bridge-foundations-with-micropiles-3d-finite-element-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109238.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">145</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> Exploring Students’ Views on Science Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Alshammari">Ahmad Alshammari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focused on exploring the students’ views about the science education in intermediate stage in State of Kuwait. This study used Social-Culture Theory (SCT) as a theoretical framework to understand the science curriculum reform process through the socio-cultural context and to discuss and explain the study findings. This study used a multi-method design, with both quantitative and qualitative methods to collect the data: students’ questionnaires and interviews. The study sample was selected randomly. First, the questionnaire was conducted with 647 students. Then 30 students (5 in each of 6 focus groups) were chosen to conduct the in-depth interviews. The findings of this study indicated the generally negative views of most of the students about the new science curriculum. The findings showed that most of the students have a negative attitude toward science, they have difficulty understanding most of the lessons, and they do not enjoy studying the science subject. This study recommends reviewing the new science curriculum (now currently in use) and taking into account the perspectives of the students about this curriculum. Developing and adapting the new science curriculum took place without taking into consideration the socio-culture and Islamic religion of Kuwaiti students. The MoE should deal with the relationship between science and culture and between science and religion, integrating more relevant science into the curriculum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=science%20education" title="science education">science education</a>, <a href="https://publications.waset.org/abstracts/search?q=students%20views" title=" students views"> students views</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20curriculum" title=" science curriculum"> science curriculum</a>, <a href="https://publications.waset.org/abstracts/search?q=curriculum%20development" title=" curriculum development"> curriculum development</a> </p> <a href="https://publications.waset.org/abstracts/54004/exploring-students-views-on-science-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54004.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">319</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Interfacing Photovoltaic Systems to the Utility Grid: A Comparative Simulation Study to Mitigate the Impact of Unbalanced Voltage Dips</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Badr%20M.%20Alshammari">Badr M.

Firstly, the MPPT control of the PVS and its associated DC/DC converter has been analyzed in order to extract the maximum of available power. Secondly, the control system of the grid side converter (GSC) which is a three-phase voltage source inverter (VSI) has been presented. A special attention has been paid to the control algorithms of the GSC converter during grid voltages imbalances. Especially, three different control objectives are to achieve; the mitigation of the grid imbalance adverse effects, at the point of common coupling (PCC), on the injected currents, the elimination of double frequency oscillations in active power flow, and the elimination of double frequency oscillations in reactive power flow. Simulation results of two control strategies have been performed via MATLAB software in order to demonstrate the particularities of each control strategy according to power quality standards. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=renewable%20energies" title="renewable energies">renewable energies</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20systems" title=" photovoltaic systems"> photovoltaic systems</a>, <a href="https://publications.waset.org/abstracts/search?q=dc%20link" title=" dc link"> dc link</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20source%20inverter" title=" voltage source inverter"> voltage source inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20vector%20SVPWM" title=" space vector SVPWM"> space vector SVPWM</a>, <a href="https://publications.waset.org/abstracts/search?q=unbalanced%20voltage%20dips" title=" unbalanced voltage dips"> unbalanced voltage dips</a>, <a href="https://publications.waset.org/abstracts/search?q=symmetrical%20components" title=" symmetrical components"> symmetrical components</a> </p> <a href="https://publications.waset.org/abstracts/40472/interfacing-photovoltaic-systems-to-the-utility-grid-a-comparative-simulation-study-to-mitigate-the-impact-of-unbalanced-voltage-dips" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40472.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">377</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">33</span> Structuring of Multilayer Aluminum Nickel by Lift-off Process Using Cheap Negative Resist</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Talal%20Asghar">Muhammad Talal Asghar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The lift-off technique of the photoresist for metal patterning in integrated circuit (IC) packaging has been widely utilized in the field of microelectromechanical systems and semiconductor component manufacturing. The main advantage lies in cost-saving, reduction in complexity, and maturity of the process. The selection of photoresist depends upon many factors such as cost, the thickness of the resist, comfortable and valuable parameters extraction. In the present study, an extremely cheap dry film photoresist E8015 of thickness 38-micrometer is processed for the first time for edge profiling, according to the author's best knowledge. Successful extraction of the helpful parameter range for resist processing is performed. An undercut angle of 66 to 73 degrees is realized by parameter variation like exposure energy and development time. Finally, 10-micrometer thick metallic multilayer aluminum nickel is lifted off on the plain silicon wafer. Possible applications lie in controlled self-propagating reactions within structured metallic multilayer that may be utilized for IC packaging in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lift-off" title="lift-off">lift-off</a>, <a href="https://publications.waset.org/abstracts/search?q=IC%20packaging" title=" IC packaging"> IC packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=photoresist" title=" photoresist"> photoresist</a>, <a href="https://publications.waset.org/abstracts/search?q=multilayer" title=" multilayer"> multilayer</a> </p> <a href="https://publications.waset.org/abstracts/138502/structuring-of-multilayer-aluminum-nickel-by-lift-off-process-using-cheap-negative-resist" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138502.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">212</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> An Improved Particle Swarm Optimization Technique for Combined Economic and Environmental Power Dispatch Including Valve Point Loading Effects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Badr%20M.%20Alshammari">Badr M.

It aims to schedule the power generation of generators in order to minimize cost production and emission of harmful gases caused by fossil-fueled thermal units such as CO, CO<sub>2</sub>, NO<sub>x</sub>, and SO<sub>2</sub>. To solve this complicated multi-objective problem, an improved version of the particle swarm optimization technique that includes non-dominated sorting concept has been proposed. Valve point loading effects and system losses have been considered. The three-unit and ten-unit benchmark systems have been used to show the effectiveness of the suggested optimization technique for solving this kind of nonconvex problem.

The combined impact of temperature and petrophysical properties (water content, water activity, permeability and porosity) of shale was also addressed. Results showed that the capillary entry pressure of shale when it interacted with CO₂ was highly affected by temperature. In general, increasing the temperature decreased capillary entry pressure of shale. We believe that pore dilation, where pore throat size expands due to the application of heat, may have caused this decrease in capillary entry pressure of shale. However, in some cases we found that at higher temperature some shale samples showed that the temperature activated clay swelling may have caused an apparent decrease in pore throat radii of shale which translates into higher capillary entry pressure of shale. Also, our results showed that there is no distinct relationship between shale’s water content, water activity, permeability, and porosity on the capillary entry pressure of shale samples as it interacted with CO₂ at different temperatures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat" title="heat">heat</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold%20pressure" title="threshold pressure">threshold pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20sequestration" title=" CO₂ sequestration"> CO₂ sequestration</a>, <a href="https://publications.waset.org/abstracts/search?q=shale" title=" shale"> shale</a> </p> <a href="https://publications.waset.org/abstracts/148151/a-critical-appraisal-of-co2-entrance-pressure-with-heat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148151.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">114</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">30</span> A Spiral Dynamic Optimised Hybrid Fuzzy Logic Controller for a Unicycle Mobile Robot on Irregular Terrains</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20M.%20Almeshal">Abdullah M.

El-Kady </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a unified framework for assessment of reserve-based reliability levels in electric power systems. The unified approach is based on reserve-based analysis and assessment of the relationship between available generation capacities and required demand levels. The developed approach takes into account the load variations as well as contingencies which occur randomly causing some generation and/or transmission capacities to be lost (become unavailable). The calculated reserve based indices, which are important to assess the reserve capabilities of the power system for various operating scenarios are therefore probabilistic in nature. They reflect the fact that neither the load levels nor the generation or transmission capacities are known with absolute certainty. They are rather subjects to random variations and consequently. The calculated reserve-based reliability indices are all subjects to random variations where only expected values of these indices can be evaluated. This paper presents a unified approach to reserve-based reliability assessment of power systems using various reserve assessment criteria. Practical applications are also presented for demonstration purposes to the Saudi electricity power grid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assessment" title="assessment">assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20system" title=" power system"> power system</a>, <a href="https://publications.waset.org/abstracts/search?q=reserve" title=" reserve"> reserve</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability" title=" reliability"> reliability</a> </p> <a href="https://publications.waset.org/abstracts/11173/unified-assessment-of-power-system-reserve-based-reliability-levels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11173.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">617</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">28</span> Raman and Dielectric Relaxation Investigations of Polyester-CoFe₂O₄ Nanocomposites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alhulw%20H.%20Alshammari">Alhulw H.

Raman spectroscopy was applied as a sensitive structural identification technique to characterize the polyester-CoFe₂O₄ nanocomposites. The images of AFM confirmed the uniform distribution of CoFe₂O₄ inside the polymer matrix. Dielectric relaxation was employed as an important analytical technique to obtain information about the ability of the polymer nanocomposites to store and filter electrical signals. The dielectric relaxation analyses were carried out on the polyester-CoFe₂O₄ nanocomposites at different temperatures. An increase in dielectric constant ε₁ was observed for all samples with increasing temperatures due to the alignment of the electric dipoles with the applied electric field. In contrast, ε₁ decreased with increasing frequency. This is attributed to the difficulty for the electric dipoles to follow the electric field. The α relaxation peak that appeared at a high frequency shifted to higher frequencies when increasing the temperature. The activation energies for Maxwell-Wagner Sillar (MWS) changed from 0.84 to 1.01 eV, while the activation energies for α relaxations were 0.54 – 0.94 eV. The conduction mechanism for the polyester- CoFe₂O₄ nanocomposites followed the correlated barrier hopping (CBH) model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AC%20conductivity" title="AC conductivity">AC conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=activation%20energy" title=" activation energy"> activation energy</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric%20permittivity" title=" dielectric permittivity"> dielectric permittivity</a>, <a href="https://publications.waset.org/abstracts/search?q=polyester%20nanocomposites" title=" polyester nanocomposites"> polyester nanocomposites</a> </p> <a href="https://publications.waset.org/abstracts/166708/raman-and-dielectric-relaxation-investigations-of-polyester-cofe2o4-nanocomposites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166708.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">114</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">27</span> Experimental and Analytical Study of Various Types of Shear Connector Used for Cold-Formed Steel-Ferrocement Composite Beam </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Talal%20Alhajri">Talal Alhajri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmood%20M.%20Tahir"> Mahmood M.

Three types of shear connectors were studied comprised of bolts, self-drilling-screw and bar angle. The connection behavior is analysed in terms of its load-slip relationship and the failure mode. The parametric studies were performed to investigate the effect on the shear connector’s capacity by varying the number of layers of wire mesh used in ferrocement slab and types of shear connector used.

Through a critical lens that makes use of Julia Kristeva’s work on Powers of Horror and abjection, this paper suggests that the monstrous girl is the disabled woman, the abject in society. The monster is used as a metaphor for the unknown, the misunderstood, and the ‘different’ woman. Culturally Relevant Teaching (CRT) is a pedagogy that calls for making course material accessible and relevant to students. Through the study of literary texts, we are able to help create agency inside and outside the classroom. Stories are a necessary part of establishing connections across borders and boundaries. Stories are meant to raise awareness both inside and outside the classroom. The discussion is equally important, and the text is meant to facilitate relevant questions that the students need to consider when it comes to identity. Questions to consider are: what does it mean to be a ‘girl’ today, and what implications and consequences are at hand when you fail to perform this gendered identity? Gender is sometimes a fatal bond in the Middle East, and even more so, is the disability. In the case of our unnamed protagonist, she undergoes a process of un-becoming, a non-linear process of growing up. In a sense, it is a counter-Bildungsroman. The reading of this text emphasizes that a non-linear narrative is sometimes necessary for the female protagonist’s self-awareness and development. Discussion in class facilitates this sense of agency and questioning of gender and disability. <p class="card-text"><strong>Keywords:</strong> <a
