Vertical Electrical Sounding (VES) using Schlumberger array was carried out at 16 VES stations. Well logging data at four tube wells have been used to mark the super saturated zones with great discharge rate. The present paper shows a geoelectrical identification of the lithology and an estimate of the relationship between the resistivity and Dar Zarrouk parameters (transverse unit resistance and longitudinal unit conductance). The VES results revealed both homogeneous and heterogeneous nature of the subsurface strata. Aquifer is unconfined to confine in nature, and at few locations though perched aquifer has been identified, groundwater potential zones are developed in unconsolidated deposits layers and more than seven geo-electric layers are observed at some VES locations. Saturated zones thickness ranges from 5 m to 150 m, whereas at few area aquifer is beyond 150 m thick. The average anisotropy, transvers resistance and longitudinal conductance values are 0.86 %, 35750.9821 Ω.m<sup>2</sup>, 0.729 Siemens, respectively. The transverse unit resistance values fluctuate all over the aquifer system, whereas below at particular depth high values are observed, that significantly associated with the high transmissivity zones. The groundwater quality in all analyzed samples is below permissible limit according to World Health Standard (WHO). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aquifer" title="aquifer">aquifer</a>, <a href="https://publications.waset.org/abstracts/search?q=Dar%20Zarrouk%20parameters" title=" Dar Zarrouk parameters"> Dar Zarrouk parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=geoelectric%20layers" title=" geoelectric layers"> geoelectric layers</a>, <a href="https://publications.waset.org/abstracts/search?q=Tarbela%20Ghazi" title=" Tarbela Ghazi"> Tarbela Ghazi</a> </p> <a href="https://publications.waset.org/abstracts/87640/groundwater-potential-zone-identification-in-unconsolidated-aquifer-using-geophysical-techniques-around-tarbela-ghazi-district-haripur-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87640.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">197</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">81</span> The Study of Blood Consumption for Stem Cell Transplant Patients in Shahid Ghazi Tabatabaei Hospital, Tabriz, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naser%20Shagerdi%20Esmaeli">Naser Shagerdi Esmaeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Hamidpour"> Mohsen Hamidpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Parisa%20Hasankhani%20Tehrani"> Parisa Hasankhani Tehrani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background And Objective: Haematopoietic stem cell transplant is a potentially curative treatment option in various benign and malignant haematological diseases. Patients undergoing stem cell transplant procedure require blood transfusion on a daily basis. Currently, there is paucity of data from developing countries on transfusion practices. This audit was undertaken to determine the consumption of packed red blood cells (PRBCs) transfusion in the bone marrow transplant unit of the Shahid Ghazi Tabatabaei Hospital, Tabriz, Iran. Subjects And Methods: A retrospective audit was conducted for packed red cell transfusion ordering practice over a period from March 2017 to march 2018. All consecutive patients admitted for stem cell transplant procedure for various underlying diseases were included. Outcome measures used in this study were (i) cross match to transfusion (C: T) ratio and (ii) transfusion trigger. Results: During the study period, n=13 patients underwent a haematopoietic stem cell transplant. There were n=10 males and n=3 females. One patient was less than 15 years of age, while rests were adults. Median age±SD was 26.5±14.5 years (12∼54 years). The underlying diagnosis included Aplastic anemia (n=4), Thalassemia major (n=1), Multiple Myeloma (n=3), Acute leukemia (n=3), Hodgkin's lymphoma (n=1), PRCA (n=1). Grand total consumption of PRBCs during the study period was 204, while 258 products were crossmatch. The C:T ratio was 1.26. The transfusion trigger was Hb level of less than 8 gr/dl. Conclusion: The results of our BMT unit indicate that the C:T ratio and transfusion trigger is comparable to the international criteria and pioneer country in BMT transplantation. Also, we hope that our blood consumption become less than it is now. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blood%20consumption" title="blood consumption">blood consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=C%3A%20T%20ratio" title=" C: T ratio"> C: T ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=PRBCs" title=" PRBCs"> PRBCs</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%20cell%20transplant" title=" stem cell transplant"> stem cell transplant</a>, <a href="https://publications.waset.org/abstracts/search?q=tabriz" title=" tabriz"> tabriz</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran" title=" Iran"> Iran</a> </p> <a href="https://publications.waset.org/abstracts/158095/the-study-of-blood-consumption-for-stem-cell-transplant-patients-in-shahid-ghazi-tabatabaei-hospital-tabriz-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158095.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">80</span> A Variable Stiffness Approach to Vibration Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20A.%20Alotaibi">S.

When an individual selects a photo, PhotoRoom automagically removes or separates the background from other parts of the photo through the use of artificial intelligence. This will allow an individual to select their desired background and edit it as they wish. The methodology used was an observation, where various reviews and parts of the app were observed. The review section's findings showed that many people actually like the app, and some even rated it five stars. The conclusion was that PhotoRoom is one of the best photo editing apps due to its speed and accuracy in removing backgrounds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=removing%20background" title="removing background">removing background</a>, <a href="https://publications.waset.org/abstracts/search?q=app" title=" app"> app</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a> </p> <a href="https://publications.waset.org/abstracts/137271/photoroom-app" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137271.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">199</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">78</span> Correlation Matrix for Automatic Identification of Meal-Taking Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghazi%20Bouaziz">Ghazi Bouaziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Abderrahim%20Derouiche"> Abderrahim Derouiche</a>, <a href="https://publications.waset.org/abstracts/search?q=Damien%20Brulin"> Damien Brulin</a>, <a href="https://publications.waset.org/abstracts/search?q=H%C3%A9l%C3%A8ne%20Pigot"> Hélène Pigot</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20Campo"> Eric Campo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Automatic ADL classification is a crucial part of ambient assisted living technologies.

But detection of ADLs is a challenge, especially because each person has his/her own rhythm for performing them. Therefore, we used a correlation matrix to extract custom rules that enable to detect ADLs, including eating activity. Data collected from 3 different individuals between 35 and 105 days allows the extraction of personalized eating patterns. The comparison of the results of the process of eating activity extracted from the correlation matrices with the declarative data collected during the survey shows an accuracy of 90%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elderly%20monitoring" title="elderly monitoring">elderly monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=ADL%20identification" title=" ADL identification"> ADL identification</a>, <a href="https://publications.waset.org/abstracts/search?q=matrix%20correlation" title=" matrix correlation"> matrix correlation</a>, <a href="https://publications.waset.org/abstracts/search?q=meal-taking%20activity" title=" meal-taking activity"> meal-taking activity</a> </p> <a href="https://publications.waset.org/abstracts/155224/correlation-matrix-for-automatic-identification-of-meal-taking-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155224.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">93</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">77</span> Microwave Assisted Extraction (MAE) of Castor Oil from Castor Bean</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghazi%20Faisal%20Najmuldeen">Ghazi Faisal Najmuldeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosli%20Mohd%20Yunus"> Rosli Mohd Yunus</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurfarahin%20Bt%20Harun"> Nurfarahin Bt Harun</a>, <a href="https://publications.waset.org/abstracts/search?q=Mardhiana%20Binti%20Ismail"> Mardhiana Binti Ismail</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The microwave extraction has attracted great interest among the researchers. The main virtue of the microwave technique is cost-effective, time saving and simple handling procedure. Castor beans was chosen because of its high content in fatty acid, especially ricinoleic acid. The purpose of this research is to extract the castor oil by using the microwave assisted extraction (MAE) using ethanol as solvent and to investigate the influence of extraction time on castor oil yield and to characterize the main composition of the produced castor oil by using the GC-MS. It was found that there is a direct dependence between the oil yield and the time of extraction as it increases from 45% to 58% as the time increase from 10 min to 60 min. The major components of castor oil detected by GC-MS were ricinoleic acid, linoleic acid and oleic acid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microwave%20assisted%20extraction%20%28MAE%29" title="microwave assisted extraction (MAE)">microwave assisted extraction (MAE)</a>, <a href="https://publications.waset.org/abstracts/search?q=castor%20oil" title=" castor oil"> castor oil</a>, <a href="https://publications.waset.org/abstracts/search?q=ricinoleic%20acid" title=" ricinoleic acid"> ricinoleic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=linoleic%20acid" title=" linoleic acid"> linoleic acid</a> </p> <a href="https://publications.waset.org/abstracts/10844/microwave-assisted-extraction-mae-of-castor-oil-from-castor-bean" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10844.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">505</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">76</span> Requirements Gathering for Improved Software Usability and the Potential for Usage-Centred Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kholod%20J.%20Alotaibi">Kholod J.

Although methods exist to incorporate elements of usability engineering, there is a need for more balanced usability focused methods that can enhance the experience of software usability for users. In this regard, the potential for Usage-Centered Design is explored with respect to requirements gathering and is shown to lead to high software usability besides other benefits. It achieves this through its focus on usage, defining essential use cases, by conducting task modeling, encouraging user collaboration, refining requirements, and so on.

Variables were two blending ratios (100:0 and 70:30), press temperature (160°C and 180°C) and press time (180 and 300 s). Experimental boards with a target density of 750 kg m-3 were manufactured from these two particles and fibers blended with urea formaldehyde resin and compressed into targeted thickness. The effect of these manufacturing conditions on bending strength, internal bonding, water absorption and thickness swelling were determined. From this research, it can be concluded that hybridization of fibers with fronds particles improved some properties of particleboard. Empty fruit bunch fibers and fronds particleboard showed better modulus of rupture and internal bonding than fronds particleboards. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oil%20palm%20fronds" title="oil palm fronds">oil palm fronds</a>, <a href="https://publications.waset.org/abstracts/search?q=empty%20fruit%20bunch" title=" empty fruit bunch"> empty fruit bunch</a>, <a href="https://publications.waset.org/abstracts/search?q=particleboards" title=" particleboards"> particleboards</a>, <a href="https://publications.waset.org/abstracts/search?q=chemistry" title=" chemistry"> chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a> </p> <a href="https://publications.waset.org/abstracts/26030/fabrication-and-evaluation-of-particleboards-from-oil-palm-fronds-blend-with-empty-fruit-bunch-fibre" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26030.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">333</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">67</span> Bioethanol Synthesis Using Cellulose Recovered from Biowaste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghazi%20Faisal%20Najmuldeen">Ghazi Faisal Najmuldeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Noridah%20Abdullah"> Noridah Abdullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mimi%20Sakinah"> Mimi Sakinah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bioethanol is an alcohol made by fermentation, mostly from carbohydrates, Cellulosic biomass, derived from non-food sources, such as castor shell waste, is also being developed as a feedstock for ethanol production Cellulose extracted from biomass sources is considered the future feedstock for many products due to the availability and eco-friendly nature of cellulose. In this study, castor shell (CS) biowaste resulted from the extraction of Castor oil from castor seeds was evaluated as a potential source of cellulose. The cellulose was extracted after pretreatment process was done on the CS. The pretreatment process began with the removal of other extractives from CS, then an alkaline treatment, bleaching process with hydrogen peroxide, and followed by a mixture of acetic and nitric acids. CS cellulose was analysed by infrared absorption spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). The result showed that the overall process was adequate to produce cellulose with high purity and crystallinity from CS waste.

In addition, the increasing demand of Data and Internet makes fiber optics an important technology, as fiber optics has many characteristics that make it the best solution for transferring huge frames of Data from a point to another. Radio over fiber is the place where high quality RF is converted to optical signals over single mode fiber. Optimum values for the bias level and the switching voltage for Mach-Zehnder modulator are important for the performance of radio over fiber links. In this paper, we propose a method to optimize the two parameters simultaneously; the bias and the switching voltage point of the external modulator of a radio over fiber system considering RF gain. Simulation results show the optimum gain value under these two parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=OFDM" title="OFDM">OFDM</a>, <a href="https://publications.waset.org/abstracts/search?q=Mach%20Zehnder%20bias%20voltage" title=" Mach Zehnder bias voltage"> Mach Zehnder bias voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=switching%20voltage" title=" switching voltage"> switching voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=radio-over-fiber" title=" radio-over-fiber"> radio-over-fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=RF%20gain" title=" RF gain"> RF gain</a> </p> <a href="https://publications.waset.org/abstracts/82338/bias-optimization-of-mach-zehnder-modulator-considering-rf-gain-on-ofdm-radio-over-fiber-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82338.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">477</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">64</span> Development of an Efficient Algorithm for Cessna Citation X Speed Optimization in Cruise</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Georges%20Ghazi">Georges Ghazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc-Henry%20Devillers"> Marc-Henry Devillers</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruxandra%20M.%20Botez"> Ruxandra M.

Nowadays, this role has been mainly attributed to the flight management system. This system is an onboard multi-purpose computer responsible for providing the crew members with the optimized flight plan from a destination to the next. To accomplish this function, the flight management system uses a variety of look-up tables to compute the optimal speed and altitude for each flight regime instantly. Because the cruise is the longest segment of a typical flight, the proposed algorithm is focused on minimizing fuel consumption for this flight phase. In this paper, a complete methodology to estimate the aircraft performance and subsequently compute the optimal speed in cruise is presented. Results showed that the obtained performance database was accurate enough to predict the flight costs associated with the cruise phase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cessna%20Citation%20X" title="Cessna Citation X">Cessna Citation X</a>, <a href="https://publications.waset.org/abstracts/search?q=cruise%20speed%20optimization" title=" cruise speed optimization"> cruise speed optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=flight%20cost" title=" flight cost"> flight cost</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20index" title=" cost index"> cost index</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20golden%20section%20search" title=" and golden section search"> and golden section search</a> </p> <a href="https://publications.waset.org/abstracts/85266/development-of-an-efficient-algorithm-for-cessna-citation-x-speed-optimization-in-cruise" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85266.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">292</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">63</span> Assessment of Chemical and Physical Properties of Surface Water Resources in Flood Affected Area</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siti%20Hajar%20Ya%E2%80%99acob">Siti Hajar Ya’acob</a>, <a href="https://publications.waset.org/abstracts/search?q=Nor%20Sayzwani%20Sukri"> Nor Sayzwani Sukri</a>, <a href="https://publications.waset.org/abstracts/search?q=Farah%20Khaliz%20Kedri"> Farah Khaliz Kedri</a>, <a href="https://publications.waset.org/abstracts/search?q=Rozidaini%20Mohd%20Ghazi"> Rozidaini Mohd Ghazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nik%20Raihan%20Nik%20Yusoff"> Nik Raihan Nik Yusoff</a>, <a href="https://publications.waset.org/abstracts/search?q=Aweng%20A%2FL%20Eh%20Rak"> Aweng A/L Eh Rak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flood event that occurred in mid-December 2014 in East Coast of Peninsular Malaysia has driven attention from the public nationwide.

The persistence of plastic wastes in the environment formed a serious problem. They are prominent with their capability to resist microbial degradation for decades. Thus, it was crucial to find ways to eliminate the plastics without depending on conventional recycling methods, which causes the formation of more hazardous compounds and doubles the problem. In this paper, mealworms were fed with a mixture of plastic wastes such as plastic bags, Styrofoam, PE foam, and plastic tarpaulins film as the sole food source for a month. Frass was collected at the end of the test and examined using FTIR analysis. Also, the gut bacteria were isolated and identified using 16S rRNA. The results show the mineralization of plastic in the frass of plastic-fed worms when compared to control. The 16S rRNA and the BLAST analysis showed that the obtained isolate belongs to the genus Bacillus Sp especially Bacillus subtilis. Phylogenetic analysis showed their relatedness to the other Bacillus species in the NCBI database. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mealworm" title="mealworm">mealworm</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20management" title=" waste management"> waste management</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic-degrading%20bacteria" title=" plastic-degrading bacteria"> plastic-degrading bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=gut%20microbiome" title=" gut microbiome"> gut microbiome</a>, <a href="https://publications.waset.org/abstracts/search?q=Bacillus%20sp" title=" Bacillus sp"> Bacillus sp</a> </p> <a href="https://publications.waset.org/abstracts/146184/plastic-degradation-activity-of-bacillus-sp-isolated-from-the-gut-of-plastic-fed-yellow-mealworm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146184.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">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> Human Motion Capture: New Innovations in the Field of Computer Vision</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Najm%20Alotaibi">Najm Alotaibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Human motion capture has become one of the major area of interest in the field of computer vision.

However, the purpose of this paper is to differentiate the practical implications of both Islamic and conventional finance on global financial stability. The Islamic finance is asset backed financing which creates wealth through trade, commerce and believes in risk and return sharing. Islamic banking is asset driven as against to conventional banking which is liability driven. In order to introduce new financial products for market, financial innovation in Islamic finance must be within the Shari’ah parameters that are tested against the ‘Maqasid al-Shari’ah’. Interest-based system leads to income and wealth inequalities and mis-allocation of resources. Moreover, this system has absence of just and equitable aspect of distribution that may exploit either the debt holder or the financier. Such implications are reached to a tipping point that leaves only one choice: change or face continued decline and misery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=viability" title="viability">viability</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20financial%20stability" title=" global financial stability"> global financial stability</a>, <a href="https://publications.waset.org/abstracts/search?q=practical%20implications" title=" practical implications"> practical implications</a>, <a href="https://publications.waset.org/abstracts/search?q=asset%20driven" title=" asset driven"> asset driven</a>, <a href="https://publications.waset.org/abstracts/search?q=tipping%20point" title=" tipping point"> tipping point</a> </p> <a href="https://publications.waset.org/abstracts/43819/the-viability-of-islamic-finance-and-its-impact-on-global-financial-stability-evidence-from-practical-implications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43819.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">303</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">58</span> Teachers’ Perceptions of the Efficacy of Social Stories in the Development of Social Skills for Students with Autism in Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faihan%20Alotaibi">Faihan Alotaibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study explores Saudi teachers’ perceptions of the efficacy of social stories in the development of social skills in students with autism in Riyadh, Saudi Arabia in two phases.

As a consequence, there is a strong desire in the surgical community to be able to monitor and quantify the cognitive stress of a surgeon while performing surgical procedures. Quantitative cognitiveload-based feedback can also provide valuable insights during surgical training to optimize training efficiency and effectiveness. Various physiological measures have been evaluated for quantifying cognitive stress for different mental challenges. In this paper, we present a study using the cognitive stress measured by the task evoked pupillary response extracted from the time series eye-tracking measurements to predict task difficulties in a virtual reality based robotic surgery training environment.

Hence, it is required to replace these vehicles with more environment-friendly vehicles. Electric Vehicles (EVs) are promising technologies which offer both human comfort “noise, pollution” as well as reduced (or no) emissions of GHGs. In this paper, different types of EVs are reviewed and their advantages and disadvantages are identified. It is found that in terms of fuel economy, Plug-in Hybrid EVs (PHEVs) have the best fuel economy, followed by Hybrid EVs (HEVs) and ICE vehicles. Since Battery EVs (BEVs) do not use any fuel, their fuel economy is estimated as price per kilometer. Similarly, in terms of GHG emissions, BEVs are the most environmentally friendly since they do not result in any emissions while HEVs and PHEVs produce less emissions compared to the conventional ICE based vehicles. Fuel Cell EVs (FCEVs) are also zero-emission vehicles, but they have large costs associated with them. Finally, if the electricity is provided by using the renewable energy technologies through grid connection, then BEVs could be considered as zero emission vehicles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicles" title="electric vehicles">electric vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=zero%20emission%20car" title=" zero emission car"> zero emission car</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20economy" title=" fuel economy"> fuel economy</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20footprint" title=" CO₂ footprint"> CO₂ footprint</a> </p> <a href="https://publications.waset.org/abstracts/124768/a-review-on-the-potential-of-electric-vehicles-in-reducing-world-co2-footprints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124768.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">147</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">55</span> Perceptions of Corporate Governance and Business Ethics Practices in Kuwaiti Islamic and Conventional Banks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Alotaibi">Khaled Alotaibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Salah%20Alhamadi"> Salah Alhamadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibraheem%20Almubarak"> Ibraheem Almubarak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study attempts to explore both corporate governance (GC) and business ethics (BE) practices in Kuwaiti banks and the relationship between CG and BE, using an accountability framework. By examining the perceptions of key stakeholder groups, this study investigates the practices of BE and CG in Islamic banks (IBs) compared to conventional banks (CBs). We contribute to the scarce studies concerned with relations between CG and BE. We have employed a questionnaire survey method for a random sample of crucial relevant stakeholder groups. The empirical analysis of the participants’ perceptions highlights the importance of applying CG regulations and BE for Kuwaiti banks and the clear link between the two concepts. We find that the main concern is not the absence of CG and BE codes, but the lack of consistent enforcement of the regulations. Such a system needs to be strictly and effectively implemented in Kuwaiti banks to protect all stakeholders’ wealth, not only that of stockholders. There are significant patterns in the CG and BE expectations among different stakeholder groups. Most interestingly, banks’ client groups illustrate high expectations concerning CG and BE practices. <p class="card-text"><strong>Keywords:</strong> <a
