continuous research which helps to analyze polypropylene modified bituminous mix and its impact characteristics with respect to original bitumen. Three percentages of polypropylene varying from (1-3) % of the weight of bitumen have been used to alter bitumen’s performance. The temperature of 170°C has been maintained during the blending of polypropylene with bitumen. It was performed by a wet process as it has certain advantages over the dry process. A rough estimate of 210 rpm rotation speed was set to prepare the blend in a mixer for 30 minutes producing homogeneous mixture. The blended mix shows a change in physical properties in comparison with the original bitumen content. Modification shows that for a 1% increment of polypropylene, softening point increases by 1 degree, penetration values decrease gradually to 55.6, 54, 52.5, ductility values decrease gradually to 87,76, 63 and specific gravity remains the same. Then Marshall mix design is performed with 60/70 penetration grade bitumen contents varying from (4-6) % with .5% intervals. Marshall stability and flow test results indicate the increase in stability and decrease in flow. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bitumen" title="bitumen">bitumen</a>, <a href="https://publications.waset.org/abstracts/search?q=marshall" title=" marshall"> marshall</a>, <a href="https://publications.waset.org/abstracts/search?q=polypropylene" title=" polypropylene"> polypropylene</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a> </p> <a href="https://publications.waset.org/abstracts/117870/qualitative-analysis-of-bituminous-mix-modified-by-polypropylene-and-impact-characteristics-on-pavement-wearing-course" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117870.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">246</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">69</span> Analyzing the Performance Properties of Stress Absorbing Membrane Interlayer Modified with Recycled Crumb Rubber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mohammad%20Asgharzadeh">Seyed Mohammad Asgharzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Moein%20Biglari"> Moein Biglari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Asphalt overlay is the most commonly used technique of pavement rehabilitation. However, the reflective cracks which occur on the overlay surface after a short period of time are the most important distresses threatening the durability of new overlays. Stress Absorbing Membrane Interlayers (SAMIs) are used to postpone the reflective cracking in the overlays. Sand asphalt mixtures, in unmodified or crumb rubber modified (CRM) conditions, can be used as an SAMI material. In this research, the performance properties of different SAMI applications were evaluated in the laboratory using an Indirect Tensile (IDT) fracture energy. The IDT fracture energy of sand asphalt samples was also evaluated and then compared to that of the regular dense graded asphalt used as an overlay. Texas boiling water and modified Lottman tests were also conducted to evaluate the moisture susceptibility of sand asphalt mixtures. The test results showed that sand asphalt mixtures can stand higher levels of energy before cracking, and this is even more pronounced for the CRM sand mix. Sand asphalt mixture using CRM binder was also shown to be more resistance to moisture induced distresses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SAMI" title="SAMI">SAMI</a>, <a href="https://publications.waset.org/abstracts/search?q=sand%20asphalt" title=" sand asphalt"> sand asphalt</a>, <a href="https://publications.waset.org/abstracts/search?q=crumb%20rubber" title=" crumb rubber"> crumb rubber</a>, <a href="https://publications.waset.org/abstracts/search?q=indirect%20tensile%20test" title=" indirect tensile test"> indirect tensile test</a> </p> <a href="https://publications.waset.org/abstracts/72996/analyzing-the-performance-properties-of-stress-absorbing-membrane-interlayer-modified-with-recycled-crumb-rubber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72996.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">228</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">68</span> Improvement of Fatigue and Fatigue Corrosion Resistances of Turbine Blades Using Laser Cladding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sami%20I.%20Jafar">Sami I.

Understanding each generation and their growing needs will equip the workforce for when the Boomers prepare for retirement, with majority of nursing leadership positions to be potentially replaced with Gen Y nurses. In SA Medical Imaging(SAMI), at Flinders Medical Centre (FMC), it has been proven that despite challenges in succession planning, Gen Y nurse leaders are able to overcome these obstacles and provide the leadership necessary to meet the changing needs in healthcare and across organisations. Changing the culture in radiology nursing has been seen as an obstacle due to the historical nursing practices and resistance to adapt to current/future practice. As radiology advances so does the role of the nurse in imaging, this has required resilience and strong support through leadership as we change and develop the culture to keep up with the evolution of technology and standard of patient care. As a result of supporting Gen Y nurses in leadership roles, SAMI, FMC has seen a positive change in culture by creating a healthy work environment which has allowed Gen Y nurses to make long lasting contributions to the nursing profession. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=changing%20culture" title="changing culture">changing culture</a>, <a href="https://publications.waset.org/abstracts/search?q=Generation%20Y" title=" Generation Y"> Generation Y</a>, <a href="https://publications.waset.org/abstracts/search?q=radiology" title=" radiology"> radiology</a>, <a href="https://publications.waset.org/abstracts/search?q=nursing" title=" nursing"> nursing</a>, <a href="https://publications.waset.org/abstracts/search?q=leadership" title=" leadership"> leadership</a> </p> <a href="https://publications.waset.org/abstracts/124659/generation-y-leaders-in-radiology-nursing-changing-the-culture-by-understanding-the-challenges-of-a-multi-generational-workforce" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124659.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">138</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">66</span> Biodiesel Production from Canola Oil Using Trans-Esterification Process with Koh as a Catalyst</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Nafis%20Alfarizi">M.

Many alternative feedstocks that can be used among which canola oil. The purpose of this study was to determine the ability of canola oil and KOH for the trans-esterification reaction in biodiesel production. Canola oil has a very high purity that can be used as an alternative feedstock for biodiesel production and expected it will be produced biodiesel with excellent quality. In this case of study, we used trans-esterification process wherein the triglyceride is reacted with an alcohol with KOH as a catalyst, and it will produce biodiesel and glycerol as byproduct and we choose trans-esterification process because canola oil has a 0,445% FFA content. The variables studied in this research include the comparison of canola oil and methanol, temperature, time, and the percent of catalyst used. In this study the method of analysis we use GCMS and FTIR to know what the characteristic in canola oil. Development of canola oil seems to be the perfect solution to produce high-quality biodiesel. The reaction conditions resulted in 97.87% -w methyl ester (biodiesel) product by using a 0.5% wt KOH catalyst with canola and methanol ratio 1:8 at 60°C. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiesel" title="biodiesel">biodiesel</a>, <a href="https://publications.waset.org/abstracts/search?q=canola%20oil" title=" canola oil"> canola oil</a>, <a href="https://publications.waset.org/abstracts/search?q=KOH" title=" KOH"> KOH</a>, <a href="https://publications.waset.org/abstracts/search?q=trans-esterification" title=" trans-esterification"> trans-esterification</a> </p> <a href="https://publications.waset.org/abstracts/66534/biodiesel-production-from-canola-oil-using-trans-esterification-process-with-koh-as-a-catalyst" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66534.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">264</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">65</span> On the Study of the Electromagnetic Scattering by Large Obstacle Based on the Method of Auxiliary Sources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hidouri%20Sami">Hidouri Sami</a>, <a href="https://publications.waset.org/abstracts/search?q=Aguili%20Taoufik"> Aguili Taoufik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We consider fast and accurate solutions of scattering problems by large perfectly conducting objects (PEC) formulated by an optimization of the Method of Auxiliary Sources (MAS).

The results demonstrate that the ability of I&I-based adaptive cooperative control in tracking the position of non holonomic mobile robot. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonholonomic%20mobile%20robot" title="nonholonomic mobile robot">nonholonomic mobile robot</a>, <a href="https://publications.waset.org/abstracts/search?q=immersion%20and%20invariance" title=" immersion and invariance"> immersion and invariance</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20control" title=" adaptive control"> adaptive control</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertain%20nonlinear%20systems" title=" uncertain nonlinear systems"> uncertain nonlinear systems</a> </p> <a href="https://publications.waset.org/abstracts/21832/adaptive-cooperative-control-of-nonholonomic-mobile-robot-based-on-immersion-and-invariance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21832.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">498</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">61</span> A Computational Cost-Effective Clustering Algorithm in Multidimensional Space Using the Manhattan Metric: Application to the Global Terrorism Database</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Semeh%20Ben%20Salem">Semeh Ben Salem</a>, <a href="https://publications.waset.org/abstracts/search?q=Sami%20Naouali"> Sami Naouali</a>, <a href="https://publications.waset.org/abstracts/search?q=Moetez%20Sallami"> Moetez Sallami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increasing amount of collected data has limited the performance of the current analyzing algorithms. Thus, developing new cost-effective algorithms in terms of complexity, scalability, and accuracy raised significant interests. In this paper, a modified effective <em>k</em>-means based algorithm is developed and experimented. The new algorithm aims to reduce the computational load without significantly affecting the quality of the clusterings. The algorithm uses the City Block distance and a new stop criterion to guarantee the convergence. Conducted experiments on a real data set show its high performance when compared with the original <em>k</em>-means version. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pattern%20recognition" title="pattern recognition">pattern recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20terrorism%20database" title=" global terrorism database"> global terrorism database</a>, <a href="https://publications.waset.org/abstracts/search?q=Manhattan%20distance" title=" Manhattan distance"> Manhattan distance</a>, <a href="https://publications.waset.org/abstracts/search?q=k-means%20clustering" title=" k-means clustering"> k-means clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=terrorism%20data%20analysis" title=" terrorism data analysis"> terrorism data analysis</a> </p> <a href="https://publications.waset.org/abstracts/72016/a-computational-cost-effective-clustering-algorithm-in-multidimensional-space-using-the-manhattan-metric-application-to-the-global-terrorism-database" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72016.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">60</span> Evaluation of Marwit Rod El Leqah Quartz Deposits As A Strategic Source of High Purity Quartz </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suzan%20Sami%20Ibrahim">Suzan Sami Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Gad%20Shahien"> Mohamed Gad Shahien</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Quarny%20Seliem"> Ali Quarny Seliem</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Ragab%20Abukhadra"> Mostafa Ragab Abukhadra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pegmatite quartz deposits of Marwit Rod El Leqah area classify as medium purity quartz with 99.575 % average SiO2 content and therefore do not match the requirements of high technical applications (99.8 % SiO2 for solar cells, 99.8% SiO2 for electronics).

Consequently, poor and unhealthy ventilation comes about. In this paper, the authors developed an old Barajeel (Wind Catchers) approach for natural ventilation. Two Barajeels (Wind Catchers) are designed and located at both extreme ends of the built unit. The two wind catchers are made as inlet and outlet for the air movement where the rate of air changes at its best. To validate the usage of the wind catchers a CFD Software was used to simulate the operation of the wind catchers for natural ventilations for average wind speed of 2 m/s. The results show a positive solution to solve the problem of the cramped such built units.

HBV markers were tested in the sera of 3600 vaccinated children. Infected children were followed up for 1 year. Prevalence of HBV infection was 0.39 % (0.28% positive for anti-HBc, 0.03% positive for HBsAg and 0.08% positive for both). One year later, 50% of positive anti-HBc children turned negative with sustained positivity for positive HBsAg cases. HBV infection was significantly higher at age above 9 years (0.6%) compared to 0.2% at age 3-9 years and 0% at younger age (P < 0.05). Logistic analysis revealed that predictors for HBV infection were history of blood transfusion, regular medical injection, and family history of either HBV infection or drug abuse (adjusted odds ratios 6.2, 5.6, 7.6 & 19.1 respectively). HBV vaccination program produced adequate protection. Adherence to infection control measures and safe blood transfusion are recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HBV%20infection" title="HBV infection">HBV infection</a>, <a href="https://publications.waset.org/abstracts/search?q=HBV%20vaccine" title=" HBV vaccine"> HBV vaccine</a>, <a href="https://publications.waset.org/abstracts/search?q=children" title=" children"> children</a>, <a href="https://publications.waset.org/abstracts/search?q=Egypt" title=" Egypt"> Egypt</a> </p> <a href="https://publications.waset.org/abstracts/2352/hepatitis-b-virus-infection-among-egyptian-children-vaccinated-during-infancy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2352.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">444</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> Open Data for e-Governance: Case Study of Bangladesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sami%20Kabir">Sami Kabir</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadek%20Hossain%20Khoka"> Sadek Hossain Khoka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Open Government Data (OGD) refers to all data produced by government which are accessible in reusable way by common people with access to Internet and at free of cost. In line with “Digital Bangladesh” vision of Bangladesh government, the concept of open data has been gaining momentum in the country. Opening all government data in digital and customizable format from single platform can enhance e-governance which will make government more transparent to the people. This paper presents a well-in-progress case study on OGD portal by Bangladesh Government in order to link decentralized data. The initiative is intended to facilitate e-service towards citizens through this one-stop web portal.

The African translator, in this respect, is a great actor in Africa’s literary, intellectual and philosophical movement through his exploration of great literary books and highly-echoed intellectual masterpieces via translation. The paper’s hypothesis revolves around the importance of the African translator in moving from one thought to another as shifting from one language to another (French to English or English to French and Arabic). Unless the African translator is alert-minded, lively and animated, the African thoughts are stagnant and Africa is a big mire of rotten ideas. African thoughts are alive, providing that translation is vivid. The findings of the paper reveal the significance of the African translator’s multidimensional roles in keeping Africa in movement. As a pertinent recommendation, translation in Africa should be fostered and its tools should be enhanced as well to keep Africa’s thoughts in continuous mobility between geographic areas as languages are in a progressive move through translation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=African" title="African">African</a>, <a href="https://publications.waset.org/abstracts/search?q=translator" title=" translator"> translator</a>, <a href="https://publications.waset.org/abstracts/search?q=literary" title=" literary"> literary</a>, <a href="https://publications.waset.org/abstracts/search?q=globetrotter" title=" globetrotter"> globetrotter</a>, <a href="https://publications.waset.org/abstracts/search?q=movement" title=" movement"> movement</a> </p> <a href="https://publications.waset.org/abstracts/145723/the-african-translator-as-a-literary-globetrotter-in-minds-and-thoughts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145723.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">156</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> Rapid Generation of Octagonal Pyramids on Silicon Wafer for Photovoltaics by Swift Anisotropic Chemical Etching Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sami%20Iqbal">Sami Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Azam%20Hussain"> Azam Hussain</a>, <a href="https://publications.waset.org/abstracts/search?q=Weiping%20Wu"> Weiping Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Guo%20Xinli"> Guo Xinli</a>, <a href="https://publications.waset.org/abstracts/search?q=Tong%20Zhang"> Tong Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A novel octagonal upright micro-pyramid structure was generated by wet chemical anisotropic etching on a monocrystalline silicon wafer (100).

Under rigorous control and observation, the etching process' response time was maintained precisely. The experimental outcomes show a significant decrease in the optical surface reflectance of silicon wafers, with the lowest reflectance of 8.98%, as well as enhanced surface structure, periodicity, and surface area coverage of more than 85%.

Cordyceps have been used for centuries in traditional medicine in China and other Asian countries. Survey studies were carried out to determine the presence of Cordyceps and another entomopathogenic fungal floral in North Central Nigeria for two consecutive years. Thirty samples were collected, twenty-eight were identified, and two were unidentified. Most identified species belong to Ophiocordyceps species (20samples), Cordyceps species (4samples) and Isaria species (4samples). The species identified were: Cordyceps pseudomilitaris, Cordyceps tuberculata, Cordyceps cylindrical, Ophiocordyceps nutans, O. criminals, O. oxycephala, O. kniphofioides and Isaria sinclairii. The morphological and microscopic features of the collected and identified species were similar to those reported in other countries. This is the first official report on the presence of Cordyceps species in Nigeria. Further collections from different ecological regions of Nigeria will show the richness of the floral diversity of these entomopathogenic and medicinal mushrooms in Nigeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cordyceps" title="cordyceps">cordyceps</a>, <a href="https://publications.waset.org/abstracts/search?q=entomopathogenic" title=" entomopathogenic"> entomopathogenic</a>, <a href="https://publications.waset.org/abstracts/search?q=medicinal" title=" medicinal"> medicinal</a>, <a href="https://publications.waset.org/abstracts/search?q=North%20Central" title=" North Central"> North Central</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a> </p> <a href="https://publications.waset.org/abstracts/166551/cordyceps-and-related-fungi-from-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166551.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">105</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> The Valuation of Equity Book Value and Net Income of Financial Firms in Times of Financial Crisis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sami%20Adwan">Sami Adwan</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Alhaj%20Ismail"> Alaa Alhaj Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Girardone"> Claudia Girardone</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper examines the changes in the value relevance of book value of equity and net income of financial firms over the crisis period. It also examines how these changes vary with three variables, namely, fair value exposure, ownership concentration, and regulatory capital ratios. Using a sample of financial firms operating in the European Economic Area over 2005-2011, our findings suggest that the value relevance of book value of equity increases while that of net income decreases during the financial crisis. We find that more exposure to fair value accounting mitigates the impact of the crisis on the value relevance of book value of equity and net income. We also find that more concentrated ownership appears to have a mitigating impact on the changes in the value relevance of both book value of equity and net income in times of financial crisis. Finally, we find evidence that the level of regulatory capital ratios tends to have an attenuating effect on the changes in the value relevance of net income (but not book value of equity) in times of financial crisis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=value%20relevance" title="value relevance">value relevance</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20crisis" title=" financial crisis"> financial crisis</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20firms" title=" financial firms"> financial firms</a>, <a href="https://publications.waset.org/abstracts/search?q=fair%20value" title=" fair value"> fair value</a>, <a href="https://publications.waset.org/abstracts/search?q=ownership%20concentration" title=" ownership concentration"> ownership concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=regulatory%20capital" title=" regulatory capital"> regulatory capital</a> </p> <a href="https://publications.waset.org/abstracts/103677/the-valuation-of-equity-book-value-and-net-income-of-financial-firms-in-times-of-financial-crisis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103677.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">181</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Exploring Tweet Geolocation: Leveraging Large Language Models for Post-Hoc Explanations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarra%20Hasni">Sarra Hasni</a>, <a href="https://publications.waset.org/abstracts/search?q=Sami%20Faiz"> Sami Faiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, location prediction on social networks has gained significant attention, with short and unstructured texts like tweets posing additional challenges. Advanced geolocation models have been proposed, increasing the need to explain their predictions. In this paper, we provide explanations for a geolocation black-box model using LIME and SHAP, two state-of-the-art XAI (eXplainable Artificial Intelligence) methods. We extend our evaluations to Large Language Models (LLMs) as post hoc explainers for tweet geolocation. Our preliminary results show that LLMs outperform LIME and SHAP by generating more accurate explanations. Additionally, we demonstrate that prompts with examples and meta-prompts containing phonetic spelling rules improve the interpretability of these models, even with informal input data. This approach highlights the potential of advanced prompt engineering techniques to enhance the effectiveness of black-box models in geolocation tasks on social networks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=large%20language%20model" title="large language model">large language model</a>, <a href="https://publications.waset.org/abstracts/search?q=post%20hoc%20explainer" title=" post hoc explainer"> post hoc explainer</a>, <a href="https://publications.waset.org/abstracts/search?q=prompt%20engineering" title=" prompt engineering"> prompt engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20explanation" title=" local explanation"> local explanation</a>, <a href="https://publications.waset.org/abstracts/search?q=tweet%20geolocation" title=" tweet geolocation"> tweet geolocation</a> </p> <a href="https://publications.waset.org/abstracts/190334/exploring-tweet-geolocation-leveraging-large-language-models-for-post-hoc-explanations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190334.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">25</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> An Experimental Investigation on the Droplet Behavior Impacting a Hot Surface above the Leidenfrost Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaleel%20Sami%20Hamdan">Khaleel Sami Hamdan</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong-Eok%20Kim"> Dong-Eok Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang-Ki%20Moon"> Sang-Ki Moon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An appropriate model to predict the size of the droplets resulting from the break-up with the structures will help in a better understanding and modeling of the two-phase flow calculations in the simulation of a reactor core loss-of-coolant accident (LOCA). A droplet behavior impacting on a hot surface above the Leidenfrost temperature was investigated. Droplets of known size and velocity were impacted to an inclined plate of hot temperature, and the behavior of the droplets was observed by a high-speed camera. It was found that for droplets of Weber number higher than a certain value, the higher the Weber number of the droplet the smaller the secondary droplets. The COBRA-TF model over-predicted the measured secondary droplet sizes obtained by the present experiment. A simple model for the secondary droplet size was proposed using the mass conservation equation. The maximum spreading diameter of the droplets was also compared to previous correlations and a fairly good agreement was found. A better prediction of the heat transfer in the case of LOCA can be obtained with the presented model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=break-up" title="break-up">break-up</a>, <a href="https://publications.waset.org/abstracts/search?q=droplet" title=" droplet"> droplet</a>, <a href="https://publications.waset.org/abstracts/search?q=impact" title=" impact"> impact</a>, <a href="https://publications.waset.org/abstracts/search?q=inclined%20hot%20plate" title=" inclined hot plate"> inclined hot plate</a>, <a href="https://publications.waset.org/abstracts/search?q=Leidenfrost%20temperature" title=" Leidenfrost temperature"> Leidenfrost temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=LOCA" title=" LOCA"> LOCA</a> </p> <a href="https://publications.waset.org/abstracts/5059/an-experimental-investigation-on-the-droplet-behavior-impacting-a-hot-surface-above-the-leidenfrost-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5059.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">399</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">49</span> The Role of Coaching in Fostering Entrepreneurial Intention among Graduate Students in Tunisia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdellatif%20Amouri">Abdellatif Amouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Sami%20Boudabbous"> Sami Boudabbous</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The current study provides insights on the importance of entrepreneurial coaching as a source of developing entrepreneurial intentions among entrepreneurs and a determinant factor of business creation process and growth. Coaching, which implies exchange of adequate information and a mutual understanding between entrepreneurs and their partners, requires a better mutual knowledge of the representations and the perceptions of ideas which are widely present in their dealings and transactions. Therefore, to analyze entrepreneurs’ perceptions of business creation, we addressed a survey questionnaire to a group of Tunisian entrepreneurs and experts in business creation to indicate their level of approval concerning the prominence of coaching. The factor analysis indicates that more than 60% of the respondents believe that each statement reflects an aspect of coaching, with no bias to its position in the entrepreneurial process. Therefore, the image drawn from our respondents’ perceptions is that an entrepreneur is rather "constructed" and "shaped" by multiple apprenticeships both before and during the entrepreneurial act, through an accompaniment process and within interactions with trainers, consultants or professionals in starting a business. Similarly, the results indicate that the poor support structures and lack of accompaniment procedures stand as an obstacle impeding the development of entrepreneurial intention among business creators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Entrepreneurial%20Behavior" title="Entrepreneurial Behavior">Entrepreneurial Behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=Entrepreneurial%20Coaching" title=" Entrepreneurial Coaching"> Entrepreneurial Coaching</a>, <a href="https://publications.waset.org/abstracts/search?q=Entrepreneurial%20Intention" title=" Entrepreneurial Intention"> Entrepreneurial Intention</a>, <a href="https://publications.waset.org/abstracts/search?q=Perceptions" title=" Perceptions"> Perceptions</a>, <a href="https://publications.waset.org/abstracts/search?q=Venture%20Creation" title=" Venture Creation "> Venture Creation </a> </p> <a href="https://publications.waset.org/abstracts/25390/the-role-of-coaching-in-fostering-entrepreneurial-intention-among-graduate-students-in-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25390.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">438</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> Use of Simultaneous Electron Backscatter Diffraction and Energy Dispersive X-Ray Spectroscopy Techniques to Characterize High-Temperature Oxides Formed on Nickel-Based Superalloys Exposed to Super-Critical Water Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Sanayei">Mohsen Sanayei</a>, <a href="https://publications.waset.org/abstracts/search?q=Jerzy%20Szpunar"> Jerzy Szpunar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sami%20Penttil%C3%A4"> Sami Penttilä</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Exposure of Nickel-based superalloys to high temperature and harsh environment such as Super-Critical Water (SCW) environment leads to the formation of oxide scales composed of multiple and complex phases that are difficult to differentiate with conventional analysis techniques.

Given the importance of costs (CapEx and OpEx) associated to these networks, resource management is becoming increasingly important, especially how the optical circuits, called “lightpaths”, are routed throughout the network. This requires the use of efficient algorithms which provide routing strategies with the lowest cost. We focus on the lightpath routing and wavelength assignment problem, known as the RWA problem, while optimizing wavelength fragmentation over the network. Wavelength fragmentation poses a serious challenge for network operators since it leads to the misuse of the wavelength spectrum, and then to the refusal of new lightpath requests. In this paper, we first establish a new Integer Linear Program (ILP) for the problem based on a node-link formulation. This formulation is based on a multilayer approach where the original network is decomposed into several network layers, each corresponding to a wavelength. Furthermore, we propose an efficient heuristic for the problem based on a greedy algorithm followed by a post-treatment procedure. The obtained results show that the optimal solution is often reached. We also compare our results with those of other RWA heuristic methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=WDM" title="WDM">WDM</a>, <a href="https://publications.waset.org/abstracts/search?q=lightpath" title=" lightpath"> lightpath</a>, <a href="https://publications.waset.org/abstracts/search?q=RWA" title=" RWA"> RWA</a>, <a href="https://publications.waset.org/abstracts/search?q=wavelength%20fragmentation" title=" wavelength fragmentation"> wavelength fragmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20programming" title=" linear programming"> linear programming</a>, <a href="https://publications.waset.org/abstracts/search?q=heuristic" title=" heuristic"> heuristic</a> </p> <a href="https://publications.waset.org/abstracts/25101/new-approach-for-minimizing-wavelength-fragmentation-in-wavelength-routed-wdm-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25101.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">527</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Work Engagement Reducing Employee Turnover Intentions in Telecommunication Sector: The Moderator Role of Human Resource Development Climate between Work Engagement and Turnover Intentions </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pirzada%20Sami%20Ullah%20Sabri">Pirzada Sami Ullah Sabri </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study examines the relationship between work engagement (WE) and employee turnover intentions (TI) in telecommunication sector using human resource development climate (HRDC) as a moderator. Based on 538 employees of telecommunication sector Hierarchal regression analysis is employed to examine the influence of HRDC on the relationship of work engagement and turnover intentions. The result indicates the negative correlation between work engagement and turnover intentions; HRD climate support as a powerful moderator increases the work engagement and lessens the turnover intentions. The study shows the importance of favorable and supportive HRD climate which foster the work engagement of the employees in the organization.

The initial dataset to be clustered can either contain categorical or numeric data. Each type of data has its own specific clustering algorithm. In this context, two algorithms are proposed: the <em>k</em>-means for clustering numeric datasets and the <em>k</em>-modes for categorical datasets. The main encountered problem in data mining applications is clustering categorical dataset so relevant in the datasets. One main issue to achieve the clustering process on categorical values is to transform the categorical attributes into numeric measures and directly apply the <em>k</em>-means algorithm instead the <em>k</em>-modes. In this paper, it is proposed to experiment an approach based on the previous issue by transforming the categorical values into numeric ones using the relative frequency of each modality in the attributes. The proposed approach is compared with a previously method based on transforming the categorical datasets into binary values. The scalability and accuracy of the two methods are experimented. The obtained results show that our proposed method outperforms the binary method in all cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clustering" title="clustering">clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=unsupervised%20learning" title=" unsupervised learning"> unsupervised learning</a>, <a href="https://publications.waset.org/abstracts/search?q=pattern%20recognition" title=" pattern recognition"> pattern recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=categorical%20datasets" title=" categorical datasets"> categorical datasets</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20discovery" title=" knowledge discovery"> knowledge discovery</a>, <a href="https://publications.waset.org/abstracts/search?q=k-means" title=" k-means"> k-means</a> </p> <a href="https://publications.waset.org/abstracts/73588/clustering-categorical-data-using-the-k-means-algorithm-and-the-attributes-relative-frequency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73588.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">259</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> Effect of Rehabilitation on Outcomes for Persons with Traumatic Brain Injury: Results from a Single Center</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sava%C5%9F%20Karpuz">Savaş Karpuz</a>, <a href="https://publications.waset.org/abstracts/search?q=Sami%20K%C3%BC%C3%A7%C3%BCk%C5%9Fen"> Sami Küçükşen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to investigate the effectiveness of neurological rehabilitation in patients with traumatic brain injury.

The results showed that the corrosion rate of elastic pre-stresses 304 stainless steel was very little increased compared with that of as received specimens. The corrosion rate increases after applying pre-stress between (σ255 - σ 455) MPa. The microstructure showed that the austenitic grains begin to deform in the direction of applied pre-stresses. The maximum hardness at this region was (229.2) Hv, but at higher pre-stress (σ455 – σ 605) MPa unanticipated occurrence, the corrosion rate decreases. The microstructure inspection shows the deformed austenitic grain and ά-martensitic phase needle are appeared inside austenitic grains and the hardness reached the maximum value (332.433) Hv. The results showed that the corrosion rate increases at the values of pre-stresses between (σ605 – σf) MPa., which is inspected the result.

Interaction between water type and water intervals(SBR) recorded the highest values of most growth parameters by irrigation after 20 days. While the treatment (MBR)and irrigated after 25 days showed the highest values on leaf area and leaves fresh weight compared with other treatments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=grey%20water" title="grey water">grey water</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20intervals" title=" water intervals"> water intervals</a>, <a href="https://publications.waset.org/abstracts/search?q=Syngonium%20plant" title=" Syngonium plant"> Syngonium plant</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling%20water" title=" recycling water"> recycling water</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetative%20growth" title=" vegetative growth"> vegetative growth</a> </p> <a href="https://publications.waset.org/abstracts/169919/utilization-of-two-kind-of-recycling-greywater-in-irrigation-of-syngonium-sp-plants-grown-under-different-water-regime" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169919.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">108</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Experimental Evaluation of Stand Alone Solar Driven Membrane Distillation System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mejbri%20Sami">Mejbri Sami</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhani%20Khalifa"> Zhani Khalifa</a>, <a href="https://publications.waset.org/abstracts/search?q=Zarzoum%20Kamel"> Zarzoum Kamel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben%20Bacha%20Habib"> Ben Bacha Habib</a>, <a href="https://publications.waset.org/abstracts/search?q=Koschikowski%20Joachim"> Koschikowski Joachim</a>, <a href="https://publications.waset.org/abstracts/search?q=Pfeifle%20Daniel"> Pfeifle Daniel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many places worldwide, especially arid and semi-arid remote regions, are suffering from the lack of drinkable water and the situation will be aggravated in the near future. Furthermore, remote areas are characterised by lack of conventional energy sources, skilled personnel and maintenance facilities. Therefore, the development of small to medium size, stand-alone and robust solar desalination systems is needed to provide independent fresh water supply in remote areas. This paper is focused on experimental studies on compact membrane distillation (MD) solar desalination prototype located at the Mechanical Engineering Department site, Kairouan University, Kairouan, Tunisia. The pilot system is designed and manufactured as a part of a research and development project funded by the MESRS/BMBF. The pilot system is totally autonomous. The electrical energy required to operate the unit is generated through a field of 4 m² of photovoltaic panels, and the heating of feed water is provided by a field of 6 m² of solar collectors. The Kairouan plant performance of the first few months of operation is presented. The highest freshwater production of 150 L/d is obtained on a sunny day in July of 633 W/m²d. <p class="card-text"><strong>Keywords:</strong> <a
