While a long time change research has focused on the effects of single discrete change events on different employee outcomes such as job satisfaction and organizational commitment, a nascent research stream has begun to look into the potential cumulative effects of change in the context of continuous intense reforms. This case study of a large Belgian public organization aims to add to this growing literature by examining how the frequency and diversity of past changes impact employees’ appraisals of a newly introduced change. Twelve hundred survey results were analyzed using standard ordinary least squares regression. Results showed a correlation between high past change frequency and diversity and a negative appraisal of the new change. Implications for practitioners and future research are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=change%20frequency" title="change frequency">change frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=change%20diversity" title=" change diversity"> change diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20changes" title=" organizational changes"> organizational changes</a>, <a href="https://publications.waset.org/abstracts/search?q=change%20appraisal" title=" change appraisal"> change appraisal</a>, <a href="https://publications.waset.org/abstracts/search?q=change%20evaluation" title=" change evaluation"> change evaluation</a> </p> <a href="https://publications.waset.org/abstracts/147976/when-change-is-the-only-constant-the-impact-of-change-frequency-and-diversity-on-change-appraisal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147976.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">135</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">5391</span> Mature Cystic Teratomas of Ovary: A Series of 19 Cases with Rare Malignant Transformation in Three</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parveen%20Kundu">Parveen Kundu</a>, <a href="https://publications.waset.org/abstracts/search?q=Nitika%20Chawla"> Nitika Chawla</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruchi%20Agarwal"> Ruchi Agarwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Swaran%20Kaur"> Swaran Kaur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Mature cystic teratoma is a benign, most common tumor of the ovary occurring mostly in young and middle-aged females. This study consists of 19 cases of mature cystic teratomas which were received in the Department Of Pathology over a period of two years. There were malignant transformations observed in three cases, which makes it very important for pathologists to thoroughly examine the entire specimen of mature cystic teratomas. Material and Methods: Nineteen reported cases of mature cystic teratomas were received in Deptt. Of Pathology, BPS GMC Khanpur Kalan, Sonepat, over a two-year period from November 2020 to October 2022 and reviewed retrospectively. Data regarding age, size, laterality, gross, morphological features, and surgery performed were retrieved from pathological archives. Results: In our study, the most common age of presentation was the 20-40 year age group. The most common presenting complaint was fullness in the abdomen or abdominal distension. Four out of 19 cases studied cases presented with bilateral ovarian cysts. Tumor size ranged from 6 to 20 cm in diameter. In seven cases, cysts were greater than or equal to 10 cm in diameter. Three cases showed malignant transformation. Conclusion: It is very important to thoroughly examine the contralateral ovary to rule out bilateral presentation. A furthermost thorough examination is advised in tumors of size >10 cm and in tumors with solid areas to rule out any malignant transformation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=teratoma" title="teratoma">teratoma</a>, <a href="https://publications.waset.org/abstracts/search?q=ovary" title=" ovary"> ovary</a>, <a href="https://publications.waset.org/abstracts/search?q=malignant" title=" malignant"> malignant</a>, <a href="https://publications.waset.org/abstracts/search?q=transformation" title=" transformation"> transformation</a> </p> <a href="https://publications.waset.org/abstracts/169478/mature-cystic-teratomas-of-ovary-a-series-of-19-cases-with-rare-malignant-transformation-in-three" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169478.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">87</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">5390</span> Frequency Offset Estimation Schemes Based on ML for OFDM Systems in Non-Gaussian Noise Environments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Keunhong%20Chae">Keunhong Chae</a>, <a href="https://publications.waset.org/abstracts/search?q=Seokho%20Yoon"> Seokho Yoon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, frequency offset (FO) estimation schemes robust to the non-Gaussian noise environments are proposed for orthogonal frequency division multiplexing (OFDM) systems.

Alshareef</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the rapidly evolving energy landscape, the integration of renewable energy sources and the electrification of transportation are essential steps toward achieving sustainability goals. However, these advancements introduce new challenges, particularly in maintaining frequency stability due to variable photovoltaic (PV) generation and the growing demand for fast charging stations. The variability of photovoltaic (PV) generation due to weather conditions can disrupt the balance between generation and load, resulting in frequency deviations. To ensure the stability of power systems, it is imperative to develop effective under frequency load-shedding schemes. This research proposal presents an adaptive under-frequency load shedding scheme based on the power swing equation, designed explicitly for the IEEE-9 Bus Test System, that includes PV generation and fast charging stations. This research aims to address these challenges by developing an advanced scheme that dynamically disconnects fast charging stations based on power imbalances. The scheme prioritizes the disconnection of stations near affected areas to expedite system frequency stabilization. To achieve these goals, the research project will leverage the power swing equation, a widely recognized model for analyzing system dynamics during under-frequency events. By utilizing this equation, the proposed scheme will adaptively adjust the load-shedding process in real-time to maintain frequency stability and prevent power blackouts. The research findings will support the transition towards sustainable energy systems by ensuring a reliable and uninterrupted electricity supply while enhancing the resilience and stability of power systems during under-frequency events. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=load%20shedding" title="load shedding">load shedding</a>, <a href="https://publications.waset.org/abstracts/search?q=fast%20charging%20stations" title=" fast charging stations"> fast charging stations</a>, <a href="https://publications.waset.org/abstracts/search?q=pv%20generation" title=" pv generation"> pv generation</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20system%20resilience" title=" power system resilience"> power system resilience</a> </p> <a href="https://publications.waset.org/abstracts/169723/enhancing-power-system-resilience-an-adaptive-under-frequency-load-shedding-scheme-incorporating-pv-generation-and-fast-charging-stations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169723.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">81</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">5388</span> The Numerical Model of the Onset of Acoustic Oscillation in Pulse Tube Engine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexander%20I.%20Dovgyallo">Alexander I.

However, the study of the thermoacoustic systems unsteady behavior in the start, stop, and acoustic load changes modes is in the particular interest. The aim of the present study was to develop a mathematical thermal excitation model of acoustic oscillations in pulse tube engine (PTE) as a small-scale scheme of pulse tube engine operating at atmospheric air. Unlike some previous works this standing wave configuration is a fully closed system. The improvements over previous mathematical models are the following: the model allows specifying any values of porosity for regenerator, takes into account the piston weight and the friction in the cylinder and piston unit, and determines the operating frequency. The numerical method is based on the relation equations between the pressure and volume velocity variables at the ends of each element of PTE which is recorded through the appropriate transformation matrix. A solution demonstrates that the PTE operation frequency is the complex value, and it depends on the piston mass and the dynamic friction due to its movement in the cylinder. On the basis of the determined frequency thermoacoustically induced heat transport and generation of acoustic power equations were solved for channel with temperature gradient on its ends. The results of numerical simulation demonstrate the features of the initialization process of oscillation and show that that generated acoustic power more than power on the steady mode in a factor of 3…4. But doesn`t mean the possibility of its further continuous utilizing due to its existence only in transient mode which lasts only for a 30-40 sec. The experiments were carried out on small-scale PTE. The results shows that the value of acoustic power is in the range of 0.7..1.05 W for the defined frequency range f = 13..18 Hz and pressure amplitudes 11..12 kPa. These experimental data are satisfactorily correlated with the numerical modeling results. The mathematical model can be straightforwardly applied for the thermoacoustic devices with variable temperatures of thermal reservoirs and variable transduction loads which are expected to occur in practical implementations of portable thermoacoustic engines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20processes" title="nonlinear processes">nonlinear processes</a>, <a href="https://publications.waset.org/abstracts/search?q=pulse%20tube%20engine" title=" pulse tube engine"> pulse tube engine</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20excitation" title=" thermal excitation"> thermal excitation</a>, <a href="https://publications.waset.org/abstracts/search?q=standing%20wave" title=" standing wave"> standing wave</a> </p> <a href="https://publications.waset.org/abstracts/38408/the-numerical-model-of-the-onset-of-acoustic-oscillation-in-pulse-tube-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38408.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">377</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5387</span> Empowering the Citizens: The Potential of Zimbabwean Library and Information Science Schools in Contributing towards Socio-Economic Transformation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Collence%20Takaingenhamo%20Chisita">Collence Takaingenhamo Chisita</a>, <a href="https://publications.waset.org/abstracts/search?q=Munyaradzi%20Shoko"> Munyaradzi Shoko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Library and Information Science Schools play significant roles in socio–economic transformation but in most cases they are downplayed or overshadowed by other institutions, and professions. Currently Zimbabwe boasts of high literacy rate in Africa and this success would have been impossible without the contributions of library schools and related institutions. Libraries and librarians are at the epicentre of socio-economic development and their role cannot be downplayed. It is out of this context that the writer will explore the extent to which library schools are contributing towards socio-economic transformation, for example, human capital development and facilitating access to information. The writer will seek to explain and clarify how LIS schools are engaged in socio-economic transformation through supporting education and culture through community engagement. The paper will examine the LIS education models, for example, general education and Technical Vocational Education and Training (TVET) or Competency Based Education and Training (CBET). It will also seek to find out how LIS Schools are contributing to the information/knowledge economy through education, training and research. The writer will also seek to find out how LIS Education is responding to socio-economic and political dynamics in Zimbabwe amidst forces of globalisation and cultural identities. Furthermore, the writer will explore the extent to which LIS education can help to reposition Zimbabwe in the global knowledge economy. The author will examine how LIS schools integrate culture and technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=development" title="development">development</a>, <a href="https://publications.waset.org/abstracts/search?q=information%2Fknowledge%20economy" title=" information/knowledge economy"> information/knowledge economy</a>, <a href="https://publications.waset.org/abstracts/search?q=culture" title=" culture"> culture</a>, <a href="https://publications.waset.org/abstracts/search?q=empowerment" title=" empowerment"> empowerment</a>, <a href="https://publications.waset.org/abstracts/search?q=collaboration" title=" collaboration"> collaboration</a>, <a href="https://publications.waset.org/abstracts/search?q=globalisation" title=" globalisation "> globalisation </a> </p> <a href="https://publications.waset.org/abstracts/15222/empowering-the-citizens-the-potential-of-zimbabwean-library-and-information-science-schools-in-contributing-towards-socio-economic-transformation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15222.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">321</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">5386</span> Nanoindentation Behaviour and Microstructural Evolution of Annealed Single-Crystal Silicon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Woei-Shyan%20Lee">Woei-Shyan Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuo-Ling%20Chang"> Shuo-Ling Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The nanoindentation behaviour and phase transformation of annealed single-crystal silicon wafers are examined. The silicon specimens are annealed at temperatures of 250, 350 and 450ºC, respectively, for 15 minutes and are then indented to maximum loads of 30, 50 and 70 mN. The phase changes induced in the indented specimens are observed using transmission electron microscopy (TEM) and micro-Raman scattering spectroscopy (RSS). For all annealing temperatures, an elbow feature is observed in the unloading curve following indentation to a maximum load of 30 mN. Under higher loads of 50 mN and 70 mN, respectively, the elbow feature is replaced by a pop-out event. The elbow feature reveals a complete amorphous phase transformation within the indented zone, whereas the pop-out event indicates the formation of Si XII and Si III phases. The experimental results show that the formation of these crystalline silicon phases increases with an increasing annealing temperature and indentation load. The hardness and Young’s modulus both decrease as the annealing temperature and indentation load are increased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoindentation" title="nanoindentation">nanoindentation</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon" title=" silicon"> silicon</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20transformation" title=" phase transformation"> phase transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=amorphous" title=" amorphous"> amorphous</a>, <a href="https://publications.waset.org/abstracts/search?q=annealing" title=" annealing"> annealing</a> </p> <a href="https://publications.waset.org/abstracts/23123/nanoindentation-behaviour-and-microstructural-evolution-of-annealed-single-crystal-silicon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23123.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">373</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">5385</span> Socio-Spatial Transformations in Obsolete Port Regions: A Case for Istanbul-Karaköy District</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Umut%20Tu%C4%9Flu%20Karsl%C4%B1">Umut Tuğlu Karslı</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While, port function had a major role during the antiquity and medieval times, it has started to lose its significance in 19th century. In many port cities, while heavy industrial functions and ports have been moved out of the former port districts, the resulting derelict spaces have been transformed to new waterfront quarters to accommodate commercial, tourism, cultural, residential and public uses. Primary aim of these operations is to revitalize abandoned spaces of historical potential and re-establish a relationship between the city and the coast. Karakoy Port, field of this study, located in the Bosphorus, was surrounded by the city centre in time due to the transformation of urban functions, and as a result it has lost its former significance. While Karakoy has 24 hours lively residential and commercial uses in old times; in early 1980s, became a district of mechanical, plumbing and electronic parts suppliers during the day and a place for homeless at night. Today, activities for revitalization of this region continue in two forms and scales. First of these activities is the "planned transformation projects," which also includes the most important one “Galataport project”, and the second one is "spontaneous transformation," which consists of individual interventions. Galataport project that based on the idea of arranging the area specifically for tourists was prepared in 2005 and became a topic of tremendous public debate. On the other hand, the "spontaneous transformation" that is observed in the Karakoy District starts in 2004 with the foundation of “Istanbul Modern Museum”. Istanbul Modern, the first contemporary arts museum of the city, allowed the cultural integration of old naval warehouses of the port to the daily life. Following this adaptive reuse intervention, the district started to accommodate numerous art galleries, studios, café-workshops and design stores. In this context, this paper briefly examines revitalization studies in obsolete port regions, analyzes the planned and ongoing socio-spatial transformations in the specific case of Karakoy under the subjects of "planned transformation projects" and "spontaneous transformation", and realizes a critical review of the sustainability of the proposals on how to reinstate the district in the active life of Istanbul. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=port%20cities" title="port cities">port cities</a>, <a href="https://publications.waset.org/abstracts/search?q=socio-spatial%20transformation" title=" socio-spatial transformation"> socio-spatial transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20regeneration" title=" urban regeneration"> urban regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20revitalization" title=" urban revitalization"> urban revitalization</a> </p> <a href="https://publications.waset.org/abstracts/25025/socio-spatial-transformations-in-obsolete-port-regions-a-case-for-istanbul-karakoy-district" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25025.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">457</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">5384</span> Effects of Copper Oxide Doping on Hydrothermal Ageing in Alumina Toughened Zirconia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abbas">Mohamed Abbas</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramesh%20Singh"> Ramesh Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigates the hydrothermal aging behavior of undoped and copper oxide-doped alumina-toughened zirconia (ATZ). The ATZ ceramic composites underwent conventional sintering at temperatures ranging from 1250 to 1500°C with a holding time of 12 minutes. XRD analysis revealed a stable 100% tetragonal phase for conventionally sintered ATZ samples up to 1450°C, even after 100 hours of exposure. At 1500℃, XRD patterns of both undoped and doped ATZ samples showed no phase transformation after up to 3 hours of exposure to superheated steam. Extended exposure, however, resulted in phase transformation beyond 10 hours. CuO-doped ATZ samples initially exhibited lower monoclinic content, gradually increasing with aging. Undoped ATZ demonstrated better-aging resistance, maintaining ~40% monoclinic content after 100 hours. FESEM images post-aging revealed surface roughness changes due to the tetragonal-to-monoclinic phase transformation, with limited nucleation in the largest tetragonal grains. Fracture analysis exhibited macrocracks and microcracks on the transformed surface layer after aging. This study found that 0.2wt% CuO doping did not prevent the low-temperature degradation (LTD) phenomenon at elevated temperatures. Transformation zone depth (TZD) calculations supported the trend observed in the transformed monoclinic phase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alumina%20toughened%20zirconia" title="alumina toughened zirconia">alumina toughened zirconia</a>, <a href="https://publications.waset.org/abstracts/search?q=conventional%20sintering" title=" conventional sintering"> conventional sintering</a>, <a href="https://publications.waset.org/abstracts/search?q=copper%20oxide" title=" copper oxide"> copper oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrothermal%20ageing" title=" hydrothermal ageing"> hydrothermal ageing</a> </p> <a href="https://publications.waset.org/abstracts/176383/effects-of-copper-oxide-doping-on-hydrothermal-ageing-in-alumina-toughened-zirconia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176383.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">68</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">5383</span> Cancellation of Transducer Effects from Frequency Response Functions: Experimental Case Study on the Steel Plate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Zamani">P.

Mechanical devices such as accelerometers are one of the sources of lack of quality in measuring modal testing parameters. In this paper, eliminating the accelerometer’s mass effect of the frequency response of the structure is studied. So, a strategy is used for eliminating the mass effect by using sensitivity analysis. In this method, the amount of mass change and the place to measure the structure’s response with least error in frequency correction is chosen. Experimental modal testing is carried out on a steel plate and the effect of accelerometer’s mass is omitted using this strategy.

Presently, organizational change has become an integral part of corporate strategy for the majority of businesses. Such shifts have resulted in both new challenges and opportunities. The expansion of the use of information and communication technologies has driven fundamental shifts towards digital change. Organizations are being forced to revise processes, goals and overall mission in order to stay competitive in the marketplace. However, the implementation of digital transformation brings uncertainty, causes stress and raises concerns about future jobs. The study employs systematic literature review to fill the gap in understanding relationship between employee motivation and commitment during the transformation. A conceptual model proposes the antecedents (OCB and Leader Member Exchange) of employee motivation and investigates its impact on employee commitment to change. The utilized model elucidates how to maintain employee motivation and commitment in the context of organizational transformation and sets the ground for future research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=employee%20motivation" title="employee motivation">employee motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=change%20commitment" title=" change commitment"> change commitment</a>, <a href="https://publications.waset.org/abstracts/search?q=change%20management" title=" change management"> change management</a>, <a href="https://publications.waset.org/abstracts/search?q=leader%20member%20exchange" title=" leader member exchange"> leader member exchange</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20citizenship%20behavior" title=" organizational citizenship behavior"> organizational citizenship behavior</a> </p> <a href="https://publications.waset.org/abstracts/169126/analysis-of-influence-of-intrinsic-motivation-on-employee-affective-commitment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169126.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">78</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">5381</span> Characterization of current–voltage (I–V) and capacitance–voltage–frequency (C–V–f) features of Au/GaN Schottky diodes </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelaziz%20Rabehi">Abdelaziz Rabehi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The current–voltage (I–V) characteristics of Au/GaN Schottky diodes were measured at room temperature. In addition, capacitance–voltage–frequency (C–V–f) characteristics are investigated by considering the interface states (Nss) at frequency range 100 kHz to 1 MHz. From the I–V characteristics of the Schottky diode, ideality factor (n) and barrier height (Φb) values of 1.22 and 0.56 eV, respectively, were obtained from a forward bias I–V plot. In addition, the interface states distribution profile as a function of (Ess − Ev) was extracted from the forward bias I–V measurements by taking into account the bias dependence of the effective barrier height (Φe) for the Schottky diode. The C–V curves gave a barrier height value higher than those obtained from I–V measurements. This discrepancy is due to the different nature of the I–V and C–V measurement techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Schottky%20diodes" title="Schottky diodes">Schottky diodes</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20dependence" title=" frequency dependence"> frequency dependence</a>, <a href="https://publications.waset.org/abstracts/search?q=barrier%20height" title=" barrier height"> barrier height</a>, <a href="https://publications.waset.org/abstracts/search?q=interface%20states" title=" interface states "> interface states </a> </p> <a href="https://publications.waset.org/abstracts/5577/characterization-of-current-voltage-i-v-and-capacitance-voltage-frequency-c-v-f-features-of-augan-schottky-diodes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5577.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">302</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">5380</span> Decoupling Evaluation of Resource Consumption and Economic Development of Urban Industries under the View of Sustainable Development: The Case of Secondary and Tertiary Industries in Jiangsu Province, China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jianghua%20Chen">Jianghua Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sustainable urban development requires the coordination of economic growth and resource environment, and industrial transformation and upgrading is the key link. Based on the decoupling theory and the improved decoupling decomposition model, the quantitative evaluation and comprehensive analysis of the degree of decoupling between resource consumption and economic development in Jiangsu Province are conducted using the data related to the resource consumption and economic growth of the secondary and tertiary industries in Jiangsu Province from 2013 to 2018, as a way of exploring the sustainable development path of industrial transformation in Jiangsu Province. The results show that from the decoupling status, the degree of decoupling of economic development of the secondary industry to the required coke resources, water resources, and human resources is gradually deepening, and the decoupling index of economic development of the tertiary industry to the required water resources is fluctuating; from the perspective of the driving factors, the technological effect is the main driving factor to decouple the economic growth of Jiangsu Province to the resources, and the structural effect has a significant impact on the driving index of the decoupling of economic growth of the secondary and tertiary industries to the consumption of resources in Jiangsu Province.

The drive for transformation and social justice resulted in an increasing number of university students from diverse backgrounds, which in turn, lead to the establishment of Sol Plaatje University (SPU) in 2014. A re-curriculated B. Ed. programme at SPU aims to equip students with knowledge and skills to realise the aim of social justice and to enhance the transformation of the South African society. The aim of this study is to explore the experiences and perceptions of students at a diverse university campus on a curriculum that aims to promote social justice. Four education modules, with the assumption that it reflects social justice content, were selected. Four students, representative of different ethnic and language groupings found at the SPU, were chosen as participants. Data were generated by the participants through four reflective exercises on each of the modules, spread over a period of four years. The module aims, linked with the narratives of the participants' perceptions and experiences of each module, provided an overview of the enacted curriculum. A qualitative research design with an interpretivist approach informed by Vygotsky's theory of learning was used. The participants' experiences of the four modules were analysed, and their views were interpreted. The students' narratives shed light on the strengths and weaknesses of how the B.Ed. Curriculum works towards social justice and revealed student's perceptions of otherness. From the narratives it became apparent that module did promote a social justice orientation in prospective teachers trained at a university. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=student%20diversity" title="student diversity">student diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20justice" title=" social justice"> social justice</a>, <a href="https://publications.waset.org/abstracts/search?q=transformation" title=" transformation"> transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20education" title=" teacher education"> teacher education</a> </p> <a href="https://publications.waset.org/abstracts/125295/student-teachers-experiences-and-perceptions-of-a-curriculum-designed-to-promote-social-justice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125295.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">5378</span> Civic Participation in Context of Political Transformation: Case of Argentina </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kirill%20Neverov">Kirill Neverov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the paper is considered issues of civic participation in context of changing political landscape of Argentina.

The research shows the algorithms for TSP on the sparse graphs have the shorter computation time than those for TSP according to the complete graphs. We present an improved iterative algorithm to compute the sparse graphs for TSP by frequency graphs computed with frequency quadrilaterals. The iterative algorithm is enhanced by adjusting two parameters of the algorithm. The computation time of the algorithm is <em>O</em>(<em>CN</em><sub>max</sub><em>n</em><sup>2</sup>) where <em>C</em> is the iterations, <em>N</em><sub>max</sub> is the maximum number of frequency quadrilaterals containing each edge and <em>n</em> is the scale of TSP. The experimental results showed the computed sparse graphs generally have less than 5<em>n</em> edges for most of these Euclidean instances. Moreover, the maximum degree and minimum degree of the vertices in the sparse graphs do not have much difference. Thus, the computation time of the methods to resolve the TSP on these sparse graphs will be greatly reduced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frequency%20quadrilateral" title="frequency quadrilateral">frequency quadrilateral</a>, <a href="https://publications.waset.org/abstracts/search?q=iterative%20algorithm" title=" iterative algorithm"> iterative algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=sparse%20graph" title=" sparse graph"> sparse graph</a>, <a href="https://publications.waset.org/abstracts/search?q=traveling%20salesman%20problem" title=" traveling salesman problem"> traveling salesman problem</a> </p> <a href="https://publications.waset.org/abstracts/82737/an-improved-method-to-compute-sparse-graphs-for-traveling-salesman-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82737.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">233</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">5376</span> Digital Transformation in Developing Countries, A Study into Building Information Modelling Adoption in Thai Design and Engineering Small- and Medium-Sizes Enterprises</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prompt%20Udomdech">Prompt Udomdech</a>, <a href="https://publications.waset.org/abstracts/search?q=Eleni%20Papadonikolaki"> Eleni Papadonikolaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Davies"> Andrew Davies</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Building information modelling (BIM) is the major technological trend amongst built environment organisations.

This article focuses on analysis of farmer competence and farm resources which affect market strategies used by fruit farmers in Chanthaburi province of Thailand. The survey data were collected through the use of face-to-face interviews with structured questionnaires. This study identified 14 drivers related to farmer competence and farm resources of which some had significant effect on the decision to use either high-value markets or traditional markets. The results suggest that farmers who used high-value markets were better educated and they had longer experience and larger sized business. Identifying the important factors that match with the market transformation provides policy with opportunities to support the fruit farmers to increase their market power. Policies that promote business expansion of agricultural cooperatives and knowledge sharing among farmers are recommended to reduce limitations due to limited knowledge, low experience, and small business sizes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=farmer%20competence" title="farmer competence">farmer competence</a>, <a href="https://publications.waset.org/abstracts/search?q=farm%20resources" title=" farm resources"> farm resources</a>, <a href="https://publications.waset.org/abstracts/search?q=fruit%20industry" title=" fruit industry"> fruit industry</a>, <a href="https://publications.waset.org/abstracts/search?q=high-value%20markets" title=" high-value markets"> high-value markets</a>, <a href="https://publications.waset.org/abstracts/search?q=Thailand" title=" Thailand"> Thailand</a> </p> <a href="https://publications.waset.org/abstracts/101153/matching-farmer-competence-and-farm-resources-with-the-transformation-of-agri-food-marketing-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101153.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">164</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">5374</span> Educational Related Information Technology Department Transformation: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Joongsiri">P.

A novel mathematical framework developed on the acquired bi-directional images forms the basis of fault classification in four broad categories, namely, Thick1, Thick2, Thin and Normal Yarn. A discretised version of Radon transformation has been used to convert the bi-directional images into one-dimensional signals. Images were divided into training and test sample sets. Karhunen–Loève Transformation (KLT) basis is computed for the signals from the images in training set for each fault class taking top six highest energy eigen vectors. The fault class of the test image is identified by taking the Euclidean distance of its signal from its projection on the KLT basis for each sample realization and fault class in the training set. Euclidean distance applied using various techniques is used for classifying an unknown fault class. An accuracy of about 90% is achieved in detecting the correct fault class using the various techniques. The four broad fault classes were further sub classified in four sub groups based on the user set boundary limits for fault length and fault volume. The fault cross-sectional area and the fault length defines the total volume of fault. A distinct distribution of faults is found in terms of their volume and physical dimensions which can be used for monitoring the yarn faults. It has been shown from the configurational based characterization and classification that the spun yarn faults arising out of mass variation, exhibit distinct characteristics in terms of their contours, sizes and shapes apart from their frequency of occurrences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Euclidean%20distance" title="Euclidean distance">Euclidean distance</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20classification" title=" fault classification"> fault classification</a>, <a href="https://publications.waset.org/abstracts/search?q=KLT" title=" KLT"> KLT</a>, <a href="https://publications.waset.org/abstracts/search?q=Radon%20Transform" title=" Radon Transform"> Radon Transform</a> </p> <a href="https://publications.waset.org/abstracts/65167/characterization-and-monitoring-of-the-yarn-faults-using-diametric-fault-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65167.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">265</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">5372</span> Varying Frequency Application of Vermicast as Supplemented with 19-19-19+Me in the Agronomic Performance of Lettuce (Lactuca sativa)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jesryl%20B.%20Paulite">Jesryl B.

Farmers thought that this crop is not adaptable to the climate that we have in lowland. But some new varieties can tolerate warmer conditions. The massive use of pesticides in lettuce production might chronically affect human health and environment. The move of the Philippine government is toward organic. One of the organic material is vermicompost. It is an organic fertilizer that serves as soil conditioner and enhances soil fertility and promotes vigorous and healthy crop growth and Supplementation of 19-19-19+M.E. will make it better since it contains N-P-K and selected microelements to meet the nutritive requirements of the crop. The experiment was conducted at Purok 3, Brgy. Tiburcia, Kapalong, Davao del Norte from February 6, 2014 to March 4, 2014. The study was conducted to determine the effect of varying frequency application of vermicast as supplemented with 19-19-19+M.E. in lettuce. Specifically, this aimed to 1.) Identify the agronomic performance of lettuce as affected by varying frequency application of vermicast as supplemented with 19-19-19+M.E.; 2.) Assess the economic profitability of lettuce as applied with vermicast as supplemented with 19-19-19+M.E. The study was laid out in Randomized Complete Block Design (RCBD) with four treatments and three replications. The treatments were as follow: T1 – Untreated, T2 - Weekly Application, T3- Bi-weekly Application, and T4- Monthly Application. The data on percent (%) mortality were transformed using square root of transformation before Analysis of Variance (ANOVA). Results revealed not significant in terms of percent mortality in weekly and monthly application of the treatment having a mean of 1.76 % and 3.09 %. However, Significant differences were observed in agronomic performances such as; plant height with a mean of 10.63 cm in weekly application and 6.40 cm for the untreated, leaf width with a mean of 10.80 cm for the weekly application and 6.03 for the untreated, fresh weight with a mean of 25.67 g for the weekly application and 6.83 g for the untreated, and yield with a mean of 1,208.33 kg/ha for the weekly application and 327.08 kg/ha for the untreated, respectively. Results further exposed that profitability of lettuce in terms of Return of Production Cost (RPC) were; bi-weekly with 91.01 %, monthly with 68.20 %, weekly with 25.34 % and untreated (control) with 16.69 %. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agronomic%20performance" title="agronomic performance">agronomic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20profitability" title=" economic profitability"> economic profitability</a>, <a href="https://publications.waset.org/abstracts/search?q=vermicast" title=" vermicast"> vermicast</a>, <a href="https://publications.waset.org/abstracts/search?q=percent%20mortality" title=" percent mortality"> percent mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=19-19-19%2BME" title=" 19-19-19+ME "> 19-19-19+ME </a> </p> <a href="https://publications.waset.org/abstracts/23058/varying-frequency-application-of-vermicast-as-supplemented-with-19-19-19me-in-the-agronomic-performance-of-lettuce-lactuca-sativa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23058.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">5371</span> Selection of Wind Farms to Add Virtual Inertia Control to Assist the Power System Frequency Regulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20Du">W.

System inertia with high wind penetration is decreasing when conventional thermal generators are gradually replaced by wind turbines, which do not naturally contribute to inertia response. The power imbalance caused by wind power or demand fluctuations leads to the instability of system frequency. Accordingly, the need to attach the supplementary virtual inertia control to wind farms (WFs) strongly arises. When multi-wind farms are connected to the grid simultaneously, the selection of which critical WFs to install the virtual inertia control is greatly important to enhance the stability of system frequency. By building the small signal model of wind power systems considering frequency regulation, the installation locations are identified by the geometric measures of the mode observability of WFs. In addition, this paper takes the impacts of grid topology and selection of feedback control signals into consideration. Finally, simulations are conducted on a multi-wind farms power system and the results demonstrate that the designed virtual inertia control method can effectively assist the frequency regulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frequency%20regulation" title="frequency regulation">frequency regulation</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20inertia%20control" title=" virtual inertia control"> virtual inertia control</a>, <a href="https://publications.waset.org/abstracts/search?q=installation%20locations" title=" installation locations"> installation locations</a>, <a href="https://publications.waset.org/abstracts/search?q=observability" title=" observability"> observability</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20farms" title=" wind farms"> wind farms</a> </p> <a href="https://publications.waset.org/abstracts/44872/selection-of-wind-farms-to-add-virtual-inertia-control-to-assist-the-power-system-frequency-regulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44872.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">397</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">5370</span> A Study on Dilemmas and Strategies of Old Neighborhood Transformation in the Context of Inventory Renewal - Taking XU Jia Chong Study Area in Guiyang City as an Example</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dong%20Tianxiang">Dong Tianxiang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As the center of gravity of China's urban development gradually shifts from incremental construction to stock renovation, the spatial problems of old urban areas are receiving more and more attention.

The importance of robust models in this context is to compare the effect of randomly controlled experimental groups that have a sense of causality. Causal estimation is the scientific concept of comparing the pragmatic effect of treatments conditional to the given covariates rather than assessing the simple association of response and predictors. Hence, the causal effect based semiparametric transformation model was proposed to estimate the effect of treatment with the presence of possibly time-varying covariates. Due to its high flexibility and robustness, the semiparametric transformation model which shall be applied in this paper has been given much more attention for estimation of a causal effect in modeling left-truncated and right censored survival data. Despite its wide applications and popularity in estimating unknown parameters, the maximum likelihood estimation technique is quite complex and burdensome in estimating unknown parameters and unspecified transformation function in the presence of possibly time-varying covariates. Thus, to ease the complexity we proposed the modified estimating equations. After intuitive estimation procedures, the consistency and asymptotic properties of the estimators were derived and the characteristics of the estimators in the finite sample performance of the proposed model were illustrated via simulation studies and Stanford heart transplant real data example. To sum up the study, the bias of covariates was adjusted via estimating the density function for truncation variable which was also incorporated in the model as a covariate in order to relax the independence assumption of failure time and truncation time. Moreover, the expectation-maximization (EM) algorithm was described for the estimation of iterative unknown parameters and unspecified transformation function. In addition, the causal effect was derived by the ratio of the cumulative hazard function of active and passive experiments after adjusting for bias raised in the model due to the truncation variable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=causal%20estimation" title="causal estimation">causal estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=EM%20algorithm" title=" EM algorithm"> EM algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=semiparametric%20transformation%20models" title=" semiparametric transformation models"> semiparametric transformation models</a>, <a href="https://publications.waset.org/abstracts/search?q=time-to-event%20outcomes" title=" time-to-event outcomes"> time-to-event outcomes</a>, <a href="https://publications.waset.org/abstracts/search?q=time-varying%20covariate" title=" time-varying covariate "> time-varying covariate </a> </p> <a href="https://publications.waset.org/abstracts/107145/causal-estimation-for-the-left-truncation-adjusted-time-varying-covariates-under-the-semiparametric-transformation-models-of-a-survival-time" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107145.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">125</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">5368</span> Jurisprudential Terms of Istiḥālah (Transformation) in Cosmetic Products (An Analytical Study)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Sher">Hassan Sher</a> </p> <p class="card-text"><strong>Abstract:</strong></p> God has made this world with all of his essences and beautified it with his countless blessings. In Islam, no doubt, beauty is a very important characteristic but also an aspect of the body and the heart. In a world where the standards of beauty seem to change from year to year according to trends and norms. Moreover, in this world, many people want to look good and feel satisfied and will be willing to go through many ways for their ideal look. likewise, several products came into use for beautifying, cleansing, and promoting attractiveness. These products include components of cosmetics, they are utilized for health and beauty purposes. There are concerns regarding the existence of harmful or ḥarām chemicals, but With the advancement in (technology), it results in the transformation of unlawful and forbidden cosmetic products into permissible several new ingredients and products. The process of transforming certain items or products from one form to another, Muslim jurists tend to use terms like Istiḥālah (transformation).Istiḥālah is an Islamic principle unknown to many Muslims. LinguisticallyIstiḥālah carries the meaning of a transformation or a change in the nature of a thing into something else.According to the religious contact, Istiḥālah signifies a turning of a matter from a state of impurity or inedibility into a matter of different nature, name, properties, and characteristics (colour, taste, and smell) (Zuhayli, 1997). This principle, which is unanimously accepted by Muslim scholars, are breaths of fresh air to Muslims suffering from the suffocation of excessive prohibition. This will allow the invention to be utilized fully. This research tends to highlight the different ideological concepts of Istiḥālah from the perspective of Islamic Shariah and jurisprudence and its application in cosmetic products. However, the study focuses on the issues related to alcohol and pig ingredients in beauty products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=isti%E1%B8%A5%C4%81lah.%20har%C4%81m" title="istiḥālah. harām">istiḥālah. harām</a>, <a href="https://publications.waset.org/abstracts/search?q=jurisprudence" title=" jurisprudence"> jurisprudence</a>, <a href="https://publications.waset.org/abstracts/search?q=cosmetic" title=" cosmetic"> cosmetic</a>, <a href="https://publications.waset.org/abstracts/search?q=pig" title=" pig"> pig</a> </p> <a href="https://publications.waset.org/abstracts/154591/jurisprudential-terms-of-istialah-transformation-in-cosmetic-products-an-analytical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154591.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">133</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">5367</span> Measurement of Ionospheric Plasma Distribution over Myanmar Using Single Frequency Global Positioning System Receiver </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Win%20Zaw%20Hein">Win Zaw Hein</a>, <a href="https://publications.waset.org/abstracts/search?q=Khin%20Sandar%20Linn"> Khin Sandar Linn</a>, <a href="https://publications.waset.org/abstracts/search?q=Su%20Su%20Yi%20Mon"> Su Su Yi Mon</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoshitaka%20Goto"> Yoshitaka Goto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Earth ionosphere is located at the altitude of about 70 km to several 100 km from the ground, and it is composed of ions and electrons called plasma. In the ionosphere, these plasma makes delay in GPS (Global Positioning System) signals and reflect in radio waves. The delay along the signal path from the satellite to the receiver is directly proportional to the total electron content (TEC) of plasma, and this delay is the largest error factor in satellite positioning and navigation. Sounding observation from the top and bottom of the ionosphere was popular to investigate such ionospheric plasma for a long time. Recently, continuous monitoring of the TEC using networks of GNSS (Global Navigation Satellite System) observation stations, which are basically built for land survey, has been conducted in several countries. However, in these stations, multi-frequency support receivers are installed to estimate the effect of plasma delay using their frequency dependence and the cost of multi-frequency support receivers are much higher than single frequency support GPS receiver. In this research, single frequency GPS receiver was used instead of expensive multi-frequency GNSS receivers to measure the ionospheric plasma variation such as vertical TEC distribution. In this measurement, single-frequency support ublox GPS receiver was used to probe ionospheric TEC. The location of observation was assigned at Mandalay Technological University in Myanmar. In the method, the ionospheric TEC distribution is represented by polynomial functions for latitude and longitude, and parameters of the functions are determined by least-squares fitting on pseudorange data obtained at a known location under an assumption of thin layer ionosphere. The validity of the method was evaluated by measurements obtained by the Japanese GNSS observation network called GEONET. The performance of measurement results using single-frequency of GPS receiver was compared with the results by dual-frequency measurement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ionosphere" title="ionosphere">ionosphere</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20positioning%20system" title=" global positioning system"> global positioning system</a>, <a href="https://publications.waset.org/abstracts/search?q=GPS" title=" GPS"> GPS</a>, <a href="https://publications.waset.org/abstracts/search?q=ionospheric%20delay" title=" ionospheric delay"> ionospheric delay</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20electron%20content" title=" total electron content"> total electron content</a>, <a href="https://publications.waset.org/abstracts/search?q=TEC" title=" TEC"> TEC</a> </p> <a href="https://publications.waset.org/abstracts/111009/measurement-of-ionospheric-plasma-distribution-over-myanmar-using-single-frequency-global-positioning-system-receiver" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111009.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">137</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">5366</span> Evaluation of Opposite Type Heterologous MAT Genes Transfer in the Filamentous Fungi Neofusicoccum mediterraneum and Verticillium dahliae</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stavros%20Palavouzis">Stavros Palavouzis</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20Triantafyllopoulou"> Alexandra Triantafyllopoulou</a>, <a href="https://publications.waset.org/abstracts/search?q=Aliki%20Tzima"> Aliki Tzima</a>, <a href="https://publications.waset.org/abstracts/search?q=Epaminondas%20Paplomatas"> Epaminondas Paplomatas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mating-type genes are present in most filamentous fungi, even though teleomorphs for all species have not been recorded. Our study tries to explore the effect of different growth conditions on the expression of MAT genes in Neofusicoccum mediterraneum. As such, selected isolates were grown in potato dextrose broth or in water agar supplemented with pine needles under a 12 h photoperiod, as well as in constant darkness. Mycelia and spores were collected at different time points, and RNA extraction was performed, with the extracted product being used for cDNA synthesis. New primers for MAT gene expression were designed while qPCR results are underway. The second part of the study involved the isolation and cloning in a selected pGEM-T vector of the Botryosphaeria dothidea MAT1 1 1 and MAT1 2 1 mating genes, including flanking regions. As a next step, the genes were amplified using newly designed primers with engineered restriction sites. Amplicons were excised and subsequently sub-cloned in appropriate binary vectors. The constructs were afterward inserted into Agrobacterium tumefaciens and utilized for Agrobacterium-mediated transformation (ATMT) of Neofusicoccum mediterraneum. At the same time, the transformation of a Verticillium dahliae tomato race 1 strain (70V) was performed as a control. While the procedure was successful in regards to V. dahliae, transformed strains of N. mediterraneum could not be obtained. At present, a new transformation protocol, which utilizes a combination of protoplast and Agro transformation, is being evaluated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anamorph" title="anamorph">anamorph</a>, <a href="https://publications.waset.org/abstracts/search?q=heterothallism" title=" heterothallism"> heterothallism</a>, <a href="https://publications.waset.org/abstracts/search?q=perithecia" title=" perithecia"> perithecia</a>, <a href="https://publications.waset.org/abstracts/search?q=pycnidia" title=" pycnidia"> pycnidia</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20stage" title=" sexual stage"> sexual stage</a> </p> <a href="https://publications.waset.org/abstracts/138499/evaluation-of-opposite-type-heterologous-mat-genes-transfer-in-the-filamentous-fungi-neofusicoccum-mediterraneum-and-verticillium-dahliae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138499.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">5365</span> Trade-Offs between Verb Frequency and Syntactic Complexity in Children with Developmental Language Disorder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pui%20I.%20Chao">Pui I.

The aim of this study was to investigate whether verb frequency would trade-off with syntactic complexity when they talk. Method: Forty-five children with DLD, 45 chronological age matches with TD (AGE), and 45 MLU-matches with TD (MLU) who were Mandarin speakers were selected from the previous study. Language samples were collected under three contexts: conversation about children’s family and school, story retelling, and free play. MLU, verb density, utterance length difference, verb density difference, and average verb frequency were calculated and further analyzed by ANOVAs. Results: Children with DLD and their MLU matches produced shorter utterances and used fewer verbs in expressions than the AGE matches. Compared to their AGE matches, the DLD group used more verbs and verbs with lower frequency in shorter utterances but used fewer verbs and verbs with higher frequency in longer utterances. Conclusion: Mandarin-speaking children with DLD showed difficulties in verb usage and were more vulnerable to trade-offs than their age-matched peers in utterances with high demand. As a result, task demand should be taken into account as speech-language pathologists assess whether children with DLD have adequate abilities in verb usage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=developmental%20language%20disorder" title="developmental language disorder">developmental language disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=syntactic%20complexity" title=" syntactic complexity"> syntactic complexity</a>, <a href="https://publications.waset.org/abstracts/search?q=trade-offs" title=" trade-offs"> trade-offs</a>, <a href="https://publications.waset.org/abstracts/search?q=verb%20frequency" title=" verb frequency"> verb frequency</a> </p> <a href="https://publications.waset.org/abstracts/142917/trade-offs-between-verb-frequency-and-syntactic-complexity-in-children-with-developmental-language-disorder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142917.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">154</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">5364</span> Extraction of Urban Land Features from TM Landsat Image Using the Land Features Index and Tasseled Cap Transformation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Bouhennache">R.

The method uses an arithmetic calculation processed from the land features indexes and Tasseled cap transformation TC of multi spectral Thematic Mapper Landsat TM image. For this purpose the derived indexes image from the original image such SAVI the soil adjusted vegetation index, UI the urban Index, and EBBI the enhanced built up and bareness index were staked to form a new image and the bands were uncorrelated, also the Spectral Angle Mapper (SAM) and Spectral Information Divergence (SID) supervised classification approaches were first applied on the new image TM data using the reference spectra of the spectral library and subsequently the four urban, vegetation, water and soil land cover categories were extracted with their accuracy assessment.The urban features were represented using a logic calculation applied to the brightness, UI-SAVI, NDBI-greenness and EBBI- brightness data sets. The study applied to Blida and mentioned that the urban features can be mapped with an accuracy ranging from 92 % to 95%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EBBI" title="EBBI">EBBI</a>, <a href="https://publications.waset.org/abstracts/search?q=SAVI" title=" SAVI"> SAVI</a>, <a href="https://publications.waset.org/abstracts/search?q=Tasseled%20Cap%20Transformation" title=" Tasseled Cap Transformation"> Tasseled Cap Transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=UI" title=" UI"> UI</a> </p> <a href="https://publications.waset.org/abstracts/33037/extraction-of-urban-land-features-from-tm-landsat-image-using-the-land-features-index-and-tasseled-cap-transformation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33037.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">482</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">5363</span> Simulation of Reflection Loss for Carbon and Nickel-Carbon Thin Films</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Emami">M.

We have to focus on the parameters of absorbing materials such as permittivity, permeability, and thickness so that best absorbing according to our necessity can happen. The real and imaginary parts of the relative complex permittivity (ε<sub>r</sub>' and ε<sub>r</sub>") and permeability (µ<sub>r</sub>' and µ<sub>r</sub>") were obtained by simulation. The microwave absorbing property of carbon and Ni(C) is simulated in this study by MATLAB software; the simulation was in the frequency range between 2 to 12 GHz for carbon black (C), and carbon coated nickel (Ni(C)) with different thicknesses. In fact, we draw reflection loss (RL) for C and Ni-C via frequency. We have compared their absorption for 3-mm thickness and predicted for other thicknesses by using of electromagnetic wave transmission theory. The results showed that reflection loss position changes in low frequency with increasing of thickness. We found out that, in all cases, using nanocomposites as absorbance cannot get better results relative to pure nanoparticles. The frequency where absorption is maximum can determine the best choice between nanocomposites and pure nanoparticles. Also, we could find an optimal thickness for long wavelength absorbing in order to utilize them in protecting shields and covering. <p class="card-text"><strong>Keywords:</strong> <a
