Desktop computers, networking systems, high capacity storage devices and telecommunications system is currently allowing the transfer of various format of data to be processed, stored and dissemination for the purpose of decision making. Going paperless is more of benefits compare to full paper-based office. This paper proposed a model for design and implementation of e-administration system (paperless campus) for an institution of learning. If this model is design and implemented it will reduced cost and complexity of educational administration also eliminate menaces and environmental hazards attributed to paper-based administration within schools and colleges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-administration" title="e-administration">e-administration</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20administration" title=" educational administration"> educational administration</a>, <a href="https://publications.waset.org/abstracts/search?q=paperless%20campus" title=" paperless campus"> paperless campus</a>, <a href="https://publications.waset.org/abstracts/search?q=paper-based%20administration" title=" paper-based administration"> paper-based administration</a> </p> <a href="https://publications.waset.org/abstracts/16123/web-based-paperless-campus-an-approach-to-reduce-the-cost-and-complexity-of-education-administration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16123.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">380</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">175</span> Merit Order of Indonesian Coal Mining Sources to Meet the Domestic Power Plants Demand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20Siahaan">Victor Siahaan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Coal still become the most important energy source for electricity generation known for its contribution which take the biggest portion of energy mix that a country has, for example Indonesia. The low cost of electricity generation and quite a lot of resources make this energy still be the first choice to fill the portion of base load power. To realize its significance to produce electricity, it is necessary to know the amount of coal (volume) needed to ensure that all coal power plants (CPP) in a country can operate properly. To secure the volume of coal, in this study, discussion was carried out regarding the identification of coal mining sources in Indonesia, classification of coal typical from each coal mining sources, and determination of the port of loading. By using data above, the sources of coal mining are then selected to feed certain CPP based on the compatibility of the coal typical and the lowest transport cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=merit%20order" title="merit order">merit order</a>, <a href="https://publications.waset.org/abstracts/search?q=Indonesian%20coal%20mine" title=" Indonesian coal mine"> Indonesian coal mine</a>, <a href="https://publications.waset.org/abstracts/search?q=electricity" title=" electricity"> electricity</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20plant" title=" power plant"> power plant</a> </p> <a href="https://publications.waset.org/abstracts/144185/merit-order-of-indonesian-coal-mining-sources-to-meet-the-domestic-power-plants-demand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144185.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">153</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">174</span> The History and Plausible Future of Assistive Technology and What It Might Mean for Singapore Students With Disabilities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Chong">Thomas Chong</a>, <a href="https://publications.waset.org/abstracts/search?q=Irene%20Victor"> Irene Victor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses the history and plausible future of assistive technology and what it means for students with disabilities in Singapore, a country known for its high quality of education in the world. Over more than a century, students with disabilities have benefitted from relatively low-tech assistive technology (like eye-glasses, Braille, magnifiers and wheelchairs) to high-tech assistive technology including electronic mobility switches, alternative keyboards, computer-screen enlargers, text-to-speech readers, electronic sign-language dictionaries and signing avatars for individuals with hearing impairments. Driven by legislation, the use of assistive technology in many countries is becoming so ubiquitous that more and more students with disabilities are able to perform as well as if not better than their counterparts. Yet in many other learning environments where assistive technology is not affordable or mandated, the learning gaps can be quite significant. Without stronger legislation, Singapore may still have a long way to go in levelling the playing field for its students with disabilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assistive%20technology" title="assistive technology">assistive technology</a>, <a href="https://publications.waset.org/abstracts/search?q=students%20with%20disabilities" title=" students with disabilities"> students with disabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=disability%20laws%20in%20Singapore" title=" disability laws in Singapore"> disability laws in Singapore</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusiveness" title=" inclusiveness"> inclusiveness</a> </p> <a href="https://publications.waset.org/abstracts/172832/the-history-and-plausible-future-of-assistive-technology-and-what-it-might-mean-for-singapore-students-with-disabilities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172832.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">74</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">173</span> Corrosion Monitoring Techniques Impact on Concrete Durability: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20A.%20Okenyi">Victor A.

The mechanism and factors influencing reinforcement corrosion in concrete with various electrochemical monitoring techniques including non-destructive, destructive techniques and the roles of sensors have been reviewed with the aim of determining the monitoring technique that proved most effective in determining corrosion parameters and more practicable for the assessment of concrete durability. Electrochemical impedance spectroscopy (EIS) and linear polarization resistance (LPR) techniques showed great performance in evaluating corrosion kinetics and corrosion rate, respectively, while the gravimetric weight loss (GWL) technique provided accurate measurements. However, no single monitoring technique showed to be the ultimate technique, and this calls for more research work in the development of more dynamic monitoring tools capable of considering all possible corrosion factors in the corrosion monitoring process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion" title="corrosion">corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20structures" title=" concrete structures"> concrete structures</a>, <a href="https://publications.waset.org/abstracts/search?q=durability" title=" durability"> durability</a>, <a href="https://publications.waset.org/abstracts/search?q=non-destructive%20technique" title=" non-destructive technique"> non-destructive technique</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor" title=" sensor"> sensor</a> </p> <a href="https://publications.waset.org/abstracts/131142/corrosion-monitoring-techniques-impact-on-concrete-durability-a-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131142.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">182</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">172</span> Utilization of Treated Spend Pot Lining by Product from the Primary Aluminum Production in Cement and Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hang%20Tran">Hang Tran</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Brial"> Victor Brial</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Sorelli"> Luca Sorelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudiane%20Ouellet-Plamondon"> Claudiane Ouellet-Plamondon</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Conciatori"> David Conciatori</a>, <a href="https://publications.waset.org/abstracts/search?q=Laurent%20Birry"> Laurent Birry</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Spend pot lining (SPL) is a by-product generated from primary aluminum production.

This process can be conscious or unconscious. The development of new Neuromarketing techniques such as functional magnetic resonance imaging (fMRI), carries a greater understanding of how the brain functions and consumer behavior. In the results observed in different studies using fMRI, the evidence suggests that the somatic marker and future memories influence the decision-making process, adding a positive or negative emotional component to the options.

In this short brief on sexuality, I tried to discuss homosexual relationships from three attachment positions, or if you like, conditions, in relation to the compensation and correspondence hypothesis used to understand an individual's attachment orientation with an attachment figure who is seen as a secure base, safe haven, and some kind of target for proximity seeking. Drawing from the springs of virtue and hope in light of Murdock’s ‘just and love gaze’ model, I allowed myself to see the homosexual cases cited in positive terms, as I related to the situations and experiences of our homosexual ‘others’ from the guiding herald of Moltmann's theology of hope. This approach allowed me to conclusively convince readers to engage sexuality from a tolerating tendency of hope in our thinking and thoughts towards the actions and conditions of our dynamic world which is always plunging toward the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attachment" title="attachment">attachment</a>, <a href="https://publications.waset.org/abstracts/search?q=wellbeing" title=" wellbeing"> wellbeing</a>, <a href="https://publications.waset.org/abstracts/search?q=sexuality" title=" sexuality"> sexuality</a>, <a href="https://publications.waset.org/abstracts/search?q=homosexuality" title=" homosexuality"> homosexuality</a>, <a href="https://publications.waset.org/abstracts/search?q=abandonment" title=" abandonment"> abandonment</a>, <a href="https://publications.waset.org/abstracts/search?q=tolerance%20of%20hope" title=" tolerance of hope"> tolerance of hope</a>, <a href="https://publications.waset.org/abstracts/search?q=wise%20fool" title=" wise fool"> wise fool</a> </p> <a href="https://publications.waset.org/abstracts/17393/a-just-and-loving-gaze-on-sexuality-and-attachment-why-i-think-not-all-homosexual-relationships-are-borne-out-of-an-abandonment-and-attachment-crisis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17393.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">412</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">169</span> A Fast, Portable Computational Framework for Aerodynamic Simulations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Ghommem">Mehdi Ghommem</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Garcia"> Daniel Garcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Nathan%20Collier"> Nathan Collier</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Calo"> Victor Calo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We develop a fast, user-friendly implementation of a potential flow solver based on the unsteady vortex lattice method (UVLM).

Such TiO2/rGO fibers having photocatalytic property, high specific surface area and electrical conductivity can be used for photovoltaics and chemical sensing applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrospinning%20process" title="electrospinning process">electrospinning process</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20oxide" title=" titanium oxide"> titanium oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=thermally%20reduced%20graphene%20oxide" title=" thermally reduced graphene oxide"> thermally reduced graphene oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20nanofibers" title=" composite nanofibers"> composite nanofibers</a> </p> <a href="https://publications.waset.org/abstracts/5320/fabrication-of-titania-and-thermally-reduced-graphene-oxide-composite-nanofibers-by-electrospinning-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5320.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">449</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">167</span> An ANN-Based Predictive Model for Diagnosis and Forecasting of Hypertension</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Obe%20Olumide%20Olayinka">Obe Olumide Olayinka</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Balanica"> Victor Balanica</a>, <a href="https://publications.waset.org/abstracts/search?q=Eugen%20Neagoe"> Eugen Neagoe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effects of hypertension are often lethal thus its early detection and prevention is very important for everybody. In this paper, a neural network (NN) model was developed and trained based on a dataset of hypertension causative parameters in order to forecast the likelihood of occurrence of hypertension in patients. Our research goal was to analyze the potential of the presented NN to predict, for a period of time, the risk of hypertension or the risk of developing this disease for patients that are or not currently hypertensive. The results of the analysis for a given patient can support doctors in taking pro-active measures for averting the occurrence of hypertension such as recommendations regarding the patient behavior in order to lower his hypertension risk. Moreover, the paper envisages a set of three example scenarios in order to determine the age when the patient becomes hypertensive, i.e. determine the threshold for hypertensive age, to analyze what happens if the threshold hypertensive age is set to a certain age and the weight of the patient if being varied, and, to set the ideal weight for the patient and analyze what happens with the threshold of hypertensive age. <p class="card-text"><strong>Keywords:</strong> <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=hypertension" title=" hypertension"> hypertension</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20set" title=" data set"> data set</a>, <a href="https://publications.waset.org/abstracts/search?q=training%20set" title=" training set"> training set</a>, <a href="https://publications.waset.org/abstracts/search?q=supervised%20learning" title=" supervised learning"> supervised learning</a> </p> <a href="https://publications.waset.org/abstracts/26432/an-ann-based-predictive-model-for-diagnosis-and-forecasting-of-hypertension" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26432.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">392</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">166</span> Harnessing the Opportunities of E-Learning and Education in Promoting Literacy in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20Oluwaseyi%20Olowonisi">Victor Oluwaseyi Olowonisi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper aimed at presenting an overview on the concept of e-learning as it relates to higher education and how it provides opportunities for students, instructors and the government in developing the educational sector.

During actuation, consumed charges during oxidation and reduction result in different tip positions showing dynamic hysteresis effects with errors up to 25%. For a precise position control of these actuators, the characterization of the hysteresis effect due to irreversible reactions is crucial. Here, the investigation and modelling of dynamic hysteresis effects of polypyrrole-dodezylbenzenesulfonate (PPyDBS) actuators under ambient working conditions are presented. The hysteresis effect is studied for charge consumption at different frequencies and a rate-dependent hysteresis model is derived. The hysteresis model is implemented as closed loop system and is verified experimentally. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dual%20sensing-actuator" title="dual sensing-actuator">dual sensing-actuator</a>, <a href="https://publications.waset.org/abstracts/search?q=electroactive%20polymers" title=" electroactive polymers"> electroactive polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=hysteresis" title=" hysteresis"> hysteresis</a>, <a href="https://publications.waset.org/abstracts/search?q=position%20control" title=" position control"> position control</a> </p> <a href="https://publications.waset.org/abstracts/71673/modelling-of-rate-dependent-hysteresis-of-polypyrrole-dual-sensing-actuators-for-precise-position-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71673.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">386</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">162</span> Impact of Meaning in Life on Stress and Psychological Well-Being</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aisha%20Bano">Aisha Bano</a>, <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Nazir"> Rizwan Nazir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study aimed at exploring the impact of meaning in life on psychological well-being and stress among university students.

The sample was drawn using stratified random sampling technique. Data were collected using Existence Scale, Warwick-Edinburg Mental Well-Being Scale, and Stress Scale. Results of linear regression analysis reveals that high perception of meaning in life will lead to high psychological well-being and low stress among university students. Non-significant differences are found on meaning in life variable with regard to gender in the sample using t-test. Together these results suggest that meaning in life independent of gender, is a significant predictor of the levels of stress and psychological well-being being directly related to psychological well-being and inversely related to stress levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=existential%20meaning%20in%20life" title="existential meaning in life">existential meaning in life</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20well-being" title=" psychological well-being"> psychological well-being</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=students" title=" students"> students</a> </p> <a href="https://publications.waset.org/abstracts/2541/impact-of-meaning-in-life-on-stress-and-psychological-well-being" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2541.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">506</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">161</span> Distribution and Characterization of Thermal Springs in Northern Oman</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fahad%20Al%20Shidi">Fahad Al Shidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Reginald%20Victor"> Reginald Victor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was conducted in Northern Oman to assess the physical and chemical characteristics of 40 thermal springs distributed in Al Hajar Mountains in northern Oman. Physical measurements of water samples were carried out in two main seasons in Oman (winter and summer 2019). Studied springs were classified into three groups based on water temperature, four groups based on water pH values and two groups based on conductivity. Ten thermal alkaline springs that originated in Ophiolite (Samail Napp) were dominated by high pH (> 11), elevated concentration of Cl- and Na+ ions, relatively low temperature and discharge ratio. Other springs in the Hajar Super Group massif recorded high concentrations of Ca<sup>2</sup>+ and SO<sup>2-</sup><sub>4</sub> ions controlled by rock dominance, geochemistry processes, and mineralization. There was only one spring which has brackish water with very high conductivity (5500 µs/cm) and Total Dissolved Solids and it is not suitable for irrigation purposes because of the high abundance of Na+, Cl−, and Ca<sup>2</sup>+ ions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alkaline%20springs" title="alkaline springs">alkaline springs</a>, <a href="https://publications.waset.org/abstracts/search?q=geothermal" title=" geothermal"> geothermal</a>, <a href="https://publications.waset.org/abstracts/search?q=HSG" title=" HSG"> HSG</a>, <a href="https://publications.waset.org/abstracts/search?q=ophiolite" title=" ophiolite"> ophiolite</a> </p> <a href="https://publications.waset.org/abstracts/131791/distribution-and-characterization-of-thermal-springs-in-northern-oman" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131791.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">143</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">160</span> Non Immersive Virtual Laboratory Applied to Robotics Arms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20F.%20Recalde">Luis F.

It was developed using the mathematical model of the robotic arm, thus defining the parameters for virtual recreation. The environment, interaction, and behavior of the robotic arm were developed in a graphic engine (Unity3D) to emulate learning tasks such as in a robotics laboratory. In the virtual system, four inputs were developed for the movement of the robot arm; further, to program the robot, a user interface was created where the user selects the trajectory such as point to point, line, arc, or circle. Finally, the hypothesis of the industrial robotic learning process is validated through the level of knowledge acquired after using the system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20learning" title="virtual learning">virtual learning</a>, <a href="https://publications.waset.org/abstracts/search?q=robot%20arm" title=" robot arm"> robot arm</a>, <a href="https://publications.waset.org/abstracts/search?q=non-immersive%20reality" title=" non-immersive reality"> non-immersive reality</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20model" title=" mathematical model"> mathematical model</a> </p> <a href="https://publications.waset.org/abstracts/145376/non-immersive-virtual-laboratory-applied-to-robotics-arms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145376.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">99</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">159</span> A Simulative Approach for JIT Parts-Feeding Policies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhou%20BingHai">Zhou BingHai</a>, <a href="https://publications.waset.org/abstracts/search?q=Fradet%20Victor"> Fradet Victor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lean philosophy follows the simple principle of “creating more value with fewer resources”.

This paper focuses on Kanban Supermarket’s parameters and their optimization on a purely cost-based point of view. Number and size of forklifts, as well as size of the containers they carry, will be variables of the cost function which includes handling costs, inventory costs but also shortage costs. With an innovative computational approach encoded into industrial engineering software Tecnomatix and reproducing real-life conditions, a fictive assembly line is established and produces a random list of orders. Multi-scenarios are then run to study the impact of each change of parameter and the variation of costs it implies.

The aim of this work is to select and implement a low-cost static pressure data acquisition system for a NACA 2412 airfoil in an open cycle wind tunnel. This work compares wind tunnel experiment with Computational Fluid Dynamics (CFD) simulation and parametric analysis. The experiment was evaluated at Reynolds of 1.65 <em>e<sup>5</sup></em>, with increasing angles from -5° to 15°. The comparison between the approaches show good enough accuracy, between the experiment and CFD, additional parametric analysis results differ widely from the other methods, which complies with the lack of accuracy of the lateral approach due its simplicity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20tunnel" title="wind tunnel">wind tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20cost%20instrumentation" title=" low cost instrumentation"> low cost instrumentation</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20testing" title=" experimental testing"> experimental testing</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD%20simulation" title=" CFD simulation"> CFD simulation</a> </p> <a href="https://publications.waset.org/abstracts/88363/implementation-of-a-low-cost-instrumentation-for-an-open-cycle-wind-tunnel-to-evaluate-pressure-coefficient" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88363.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">180</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">157</span> Study on Parallel Shear Stress of Cement-Wood Composites Using Pinus sp. and Eucalyptus sp. in natura and Treated with CCA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20D.%20S.%20Oliveira">Rodrigo D.

An environmentally friendly alternative is the use of this waste for the production of cement-wood composites. The aim of this work was to study the possibility of using wood treated with CCA (Chromated Cooper Arsenate) in cement-wood. Specimens of Pinus sp. and Eucalyptus sp. were produced with wood raw in natura and treated with CCA. A test was performed to determine the parallel shear stress of samples after 14 days of drying, according to the Brazilian Standard NBR-7215/97. Based on the analyzed results it is concluded that the use of wood treated with CCA is not feasible in cement-wood production, because the composite samples of treated wood showed lower mechanical strength in shear stress than those with wood in natura. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=waste%20recovery" title="waste recovery">waste recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20composites" title=" wood composites"> wood composites</a>, <a href="https://publications.waset.org/abstracts/search?q=cement-wood" title=" cement-wood"> cement-wood</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20preservation" title=" wood preservation"> wood preservation</a>, <a href="https://publications.waset.org/abstracts/search?q=chromated%20copper%20arsenate" title=" chromated copper arsenate"> chromated copper arsenate</a> </p> <a href="https://publications.waset.org/abstracts/13252/study-on-parallel-shear-stress-of-cement-wood-composites-using-pinus-sp-and-eucalyptus-sp-in-natura-and-treated-with-cca" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13252.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">620</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">156</span> Big Data Analytics and Data Security in the Cloud via Fully Homomorphic Encyption Scheme</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20Onomza%20Waziri">Victor Onomza Waziri</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20K.%20Alhassan"> John K.

This has led a large number of universities to integrate this type of technology into their daily learning and teaching activities in order to facilitate the education process for both learners and teachers. On the other hand, in some developing countries such as Saudi Arabia, educators have seldom used this technology. As a result, this study was conducted in order to investigate the factors that impede teachers’ use of technology (LMSs) in their teaching in Saudi Arabian institutions. This study used a qualitative approach. Eight participants were invited to take part in this study, and they were asked to give their opinions about the most significant factors that prevented them from integrating technology into their daily activities. The results revealed that a lack of LMS skills, interest in and knowledge about the LMS among teachers were the most significant factors impeding them from using technology in their lessons. The participants suggested that incentive training should be provided to reduce these challenges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LMS" title="LMS">LMS</a>, <a href="https://publications.waset.org/abstracts/search?q=factors" title=" factors"> factors</a>, <a href="https://publications.waset.org/abstracts/search?q=KSA" title=" KSA"> KSA</a>, <a href="https://publications.waset.org/abstracts/search?q=teachers" title=" teachers"> teachers</a> </p> <a href="https://publications.waset.org/abstracts/98970/factors-affecting-and-impeding-teachers-use-of-learning-management-system-in-kingdom-of-saudi-arabia-universities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98970.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">129</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">154</span> Quantifying Stability of Online Communities and Its Impact on Disinformation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20Chomel">Victor Chomel</a>, <a href="https://publications.waset.org/abstracts/search?q=Maziyar%20Panahi"> Maziyar Panahi</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Chavalarias"> David Chavalarias</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Misinformation has taken an increasingly worrying place in social media. Propagation patterns are closely linked to the structure of communities. This study proposes a method of community analysis based on a combination of centrality indicators for the network and its main communities. The objective is to establish a link between the stability of the communities over time, the social ascension of its members internally, and the propagation of information in the community. To this end, data from the debates about global warming and political communities on Twitter have been collected, and several tens of millions of tweets and retweets have helped us better understand the structure of these communities. The quantification of this stability allows for the study of the propagation of information of any kind, including disinformation. Our results indicate that the most stable communities over time are the ones that enable the establishment of nodes capturing a large part of the information and broadcasting its opinions. Conversely, communities with a high turnover and social ascendancy only stabilize themselves strongly in the face of adversity and external events but seem to offer a greater diversity of opinions most of the time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community%20analysis" title="community analysis">community analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=disinformation" title=" disinformation"> disinformation</a>, <a href="https://publications.waset.org/abstracts/search?q=misinformation" title=" misinformation"> misinformation</a>, <a href="https://publications.waset.org/abstracts/search?q=Twitter" title=" Twitter"> Twitter</a> </p> <a href="https://publications.waset.org/abstracts/128710/quantifying-stability-of-online-communities-and-its-impact-on-disinformation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128710.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">153</span> Emerging Threats and Adaptive Defenses: Navigating the Future of Cybersecurity in a Hyperconnected World</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olasunkanmi%20Jame%20Ayodeji">Olasunkanmi Jame Ayodeji</a>, <a href="https://publications.waset.org/abstracts/search?q=Adebayo%20Adeyinka%20Victor"> Adebayo Adeyinka Victor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In a hyperconnected world, cybersecurity faces a continuous evolution of threats that challenge traditional defence mechanisms.

Its main goal is to identify potential consumers who have the ideal characteristics to establish a profitable and long-term relationship with a certain organization. Social networks can be an important source of data for identifying and qualifying leads since interest in specific products or services can be identified from the users’ expressed feelings of (dis)satisfaction. In this context, this work proposes the use of machine learning techniques and sentiment analysis as an extra step in the lead qualification process in order to improve it. In addition to machine learning models, sentiment analysis or opinion mining can be used to understand the evaluation that the user makes of a particular service, product, or brand.

With the use of manual record keeping, the criminal records can easily be manipulated by people in charge. The focus of this research work is to design a web-based application system for criminal record in Nigeria, towards elimination of challenges (such as loss of criminal records, in-efficiency in criminal record keeping, data manipulation, and other attendant problems of paper-based record keeping) which surrounds manual processing currently in use. The product of this research work will also help to minimize crime rate in our country since the opportunities and benefits lost as a result of a criminal record create will a lifelong barriers for anyone attempting to overcome a criminal past in our country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=court%20of%20law" title="court of law">court of law</a>, <a href="https://publications.waset.org/abstracts/search?q=criminal" title=" criminal"> criminal</a>, <a href="https://publications.waset.org/abstracts/search?q=criminal%20diary" title=" criminal diary"> criminal diary</a>, <a href="https://publications.waset.org/abstracts/search?q=criminal%20evidence" title=" criminal evidence"> criminal evidence</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a>, <a href="https://publications.waset.org/abstracts/search?q=web-based" title=" web-based"> web-based</a> </p> <a href="https://publications.waset.org/abstracts/16125/web-based-criminal-diary-paperless-criminal-evidence-for-federal-republic-of-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16125.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">149</span> Prediction of Maximum Inter-Story Drifts of Steel Frames Using Intensity Measures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ed%C3%A9n%20Boj%C3%B3rquez">Edén Bojórquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Baca"> Victor Baca</a>, <a href="https://publications.waset.org/abstracts/search?q=Alfredo%20Reyes-Salazar"> Alfredo Reyes-Salazar</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Gonz%C3%A1lez"> Jorge González</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, simplified equations to predict maximum inter-story drift demands of steel framed buildings are proposed in terms of two ground motion intensity measures based on the acceleration spectral shape.

This study reports the development and characterization of a biphasic scaffold based on the assembly of a cartilage phase constituted by fibroin biofunctionalized with bovine cartilage matrix; cellularized with differentiated pre-chondrocytes from adipose tissue stem cells (autologous) and well attached to a bone phase (bone bovine decellularized) to mimic the structure of the nature of native tissue and to promote the cartilage regeneration in a model of joint damage in pigs. Biphasic scaffolds were assembled by fibroin crystallization with methanol. The histological and ultrastructural architectures were evaluated by optical and scanning electron microscopy respectively. Mechanical tests were conducted to evaluate Young's modulus of the implant. For the biological evaluation, pre-chondrocytes were loaded onto the scaffolds and cellular adhesion, proliferation, and gene expression analysis of cartilage extracellular matrix components was performed. The scaffolds that were cellularized and matured for 10 days were implanted into critical 3 mm in diameter and 9-mm in depth osteochondral defects in a porcine model (n=4). Three treatments were applied per knee: Group 1: monophasic cellular scaffold (MS) (single chondral phase), group 2: biphasic scaffold, cellularized only in the chondral phase (BS1), group 3: BS cellularized in both bone and chondral phases (BS2). Simultaneously, a control without treatment was evaluated. After 4 weeks of surgery, integration and regeneration tissues were analyzed by x-rays, histology and immunohistochemistry evaluation. The mechanical assessment showed that the acellular biphasic composites exhibited Young's modulus of 805.01 kPa similar to native cartilage (400-800 kPa). In vitro biological studies revealed the chondroinductive ability of the biphasic implant, evidenced by an increase in sulfated glycosaminoglycan (GAGs) and type II collagen, both secreted by the chondrocytes cultured on the scaffold during 28 days. No evidence of adverse or inflammatory reactions was observed in the in vivo trial; however, In group 1, the defects were not reconstructed. In group 2 and 3 a good integration of the implant with the surrounding tissue was observed. Defects in group 2 were fulfilled by hyaline cartilage and normal bone. Group 3 defects showed fibrous repair tissue. In conclusion; our findings demonstrated the efficacy of biphasic and bioactive scaffold based on silk fibroin, which entwined chondroinductive features and biomechanical capability with appropriate integration with the surrounding tissue, representing a promising alternative for osteochondral tissue-engineering applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biphasic%20scaffold" title="biphasic scaffold">biphasic scaffold</a>, <a href="https://publications.waset.org/abstracts/search?q=extracellular%20cartilage%20matrix" title=" extracellular cartilage matrix"> extracellular cartilage matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=silk%20fibroin" title=" silk fibroin"> silk fibroin</a>, <a href="https://publications.waset.org/abstracts/search?q=osteochondral%20tissue%20engineering" title=" osteochondral tissue engineering"> osteochondral tissue engineering</a> </p> <a href="https://publications.waset.org/abstracts/104390/the-role-of-a-biphasic-implant-based-on-a-bioactive-silk-fibroin-for-osteochondral-tissue-regeneration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104390.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">153</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">147</span> Drama, a Microcosm of Life Experiences: An Analysis of Symbolic Order and Social Relationships in Olu Obafemi’s Play</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20Ademulegun%20Arijeniwa">Victor Ademulegun Arijeniwa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This is a sociolinguistic study of Olu Obafemi’s Naira Has No Gender as a microcosm of life experiences. The paper assesses how Olu Obafemi’s use of language in the dramatic world serves as both social relationships and symbolic order of communicative roadmap that are capable of yielding well expressed and richly articulated sociolinguistic implications. Being the interface between language and social institutions, sociolinguistics and its application is highly utilitarian in linguistics analysis, especially where the language of a text appears to be deeply tensed, such as found in dramatic texts. The aim of this paper has been (i) to assess the symbolic orderly presentation of form in Olu Obafemi’Naira Has No Gender; (ii) to find out the linguistic elements and textual organization that represent social relationships in Olu Obafemi’s Naira Has No Gender. Using qualitative research design in data generation with insights from John Gumperz Interactional Sociolinguistics Theory with particular reference to contextualization cues and miscommunication, the paper identifies the implication of the dramatic discourse on society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sociolinguistics"
