Moreover, the PEF-CSA is compared with two classical compressed indexing methods, Ferragina and Manzini implementation (FMI) and Sad-CSA on different type and size files in Pizza & Chili. The PEF-CSA performs better on the existing data in terms of the compression ratio, count, and locates time except for the evenly distributed data such as proteins data. The observations of the experiments are that the distribution of the φ is more important than the alphabet size on the compression ratio. Unevenly distributed data φ makes better compression effect, and the larger the size of the hit counts, the longer the count and locate time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressed%20suffix%20array" title="compressed suffix array">compressed suffix array</a>, <a href="https://publications.waset.org/abstracts/search?q=self-indexing" title=" self-indexing"> self-indexing</a>, <a href="https://publications.waset.org/abstracts/search?q=partitioned%20Elias-Fano" title=" partitioned Elias-Fano"> partitioned Elias-Fano</a>, <a href="https://publications.waset.org/abstracts/search?q=PEF-CSA" title=" PEF-CSA"> PEF-CSA</a> </p> <a href="https://publications.waset.org/abstracts/65986/compressed-suffix-arrays-to-self-indexes-based-on-partitioned-elias-fano" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65986.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">252</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">70</span> Layout Optimization of a Start-up COVID-19 Testing Kit Manufacturing Facility</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Poojan%20Vora">Poojan Vora</a>, <a href="https://publications.waset.org/abstracts/search?q=Hardik%20Pancholi"> Hardik Pancholi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanket%20Tajane"> Sanket Tajane</a>, <a href="https://publications.waset.org/abstracts/search?q=Harsh%20Shah"> Harsh Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20Keedy"> Elias Keedy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The global COVID-19 pandemic has affected the industry drastically in many ways. Even though the vaccine is being distributed quickly and despite the decreasing number of positive cases, testing is projected to remain a key aspect of the ‘new normal’. Improving existing plant layout and improving safety within the facility are of great importance in today’s industries because of the need to ensure productivity optimization and reduce safety risks. In practice, it is essential for any manufacturing plant to reduce nonvalue adding steps such as the movement of materials and rearrange similar processes. In the current pandemic situation, optimized layouts will not only increase safety measures but also decrease the fixed cost per unit manufactured. In our case study, we carefully studied the existing layout and the manufacturing steps of a new Texas start-up company that manufactures COVID testing kits. The effects of production rate are incorporated with the computerized relative allocation of facilities technique (CRAFT) algorithm to improve the plant layout and estimate the optimization parameters. Our work reduces the company’s material handling time and increases their daily production. Real data from the company are used in the case study to highlight the importance of colleges in fostering small business needs and improving the collaboration between college researchers and industries by using existing models to advance best practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computerized%20relative%20allocation%20of%20facilities%20technique" title="computerized relative allocation of facilities technique">computerized relative allocation of facilities technique</a>, <a href="https://publications.waset.org/abstracts/search?q=facilities%20planning" title=" facilities planning"> facilities planning</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=start-up%20business" title=" start-up business"> start-up business</a> </p> <a href="https://publications.waset.org/abstracts/135190/layout-optimization-of-a-start-up-covid-19-testing-kit-manufacturing-facility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135190.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">69</span> Multi-Criterial Analysis: Potential Regions and Height of Wind Turbines, Rio de Janeiro, Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudio%20L.%20M.%20Souza">Claudio L.

This work presents results obtained by multi-criteria decision analysis, and it establishes a hierarchy, regarding the installation of wind farms, among geopolicy regions in the state of ‘Rio de Janeiro’, Brazil: ‘Regiao Norte-RN’, ‘Regiao dos Lagos-RL’ and ‘Regiao Serrana-RS’. The wind regime map indicates only these three possible regions with an average annual wind speed of above of 6.0 m/s. The method applied was the Analytical Hierarchy Process-AHP, designed to prioritize and rank the three regions based on four criteria as follows: 1) potential of the site and average wind speeds of above 6.0 ms-¹, 2) average land value, 3) distribution and interconnection to electric network with the highest number of electricity stations, and 4) accessibility with proximity and quality of highways and flat topography. The values of energy generation were calculated for wind turbines 50, 75, and 100 meters high, considering the production of site (GWh/Km²) and annual production (GWh). The weight of each criterion was attributed by six engineers and by analysis of Road Map, the Map of the Electric System, the Map of Wind Regime and the Annual Land Value Report. The results indicated that in 'RS', the demand was estimated at 2,000 GWh, so a wind farm can operate efficiently in 50 m turbines. This region is mainly mountainous with difficult access and lower land value. With respect to ‘RL’, the wind turbines have to be installed at a height of 75 m high to reach a demand of 6,300 GWh. This region is very flat, with easy access, and low land value. Finally, the ‘NR’ was evaluated as very flat and with expensive lands. In this case, wind turbines with 100 m can reach an annual production of 19,000 GWh. In this Region, the coast area was classified as of greater logistic, productivity and economic potential. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AHP" title="AHP">AHP</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20energy" title=" wind energy"> wind energy</a> </p> <a href="https://publications.waset.org/abstracts/88888/multi-criterial-analysis-potential-regions-and-height-of-wind-turbines-rio-de-janeiro-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88888.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">151</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> Design of a Dietetic Food: Case of Lebanese Kishk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Henri%20El%20Zakhem">Henri El Zakhem</a>, <a href="https://publications.waset.org/abstracts/search?q=Dona%20Shalhoub"> Dona Shalhoub</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20Atallah"> Elias Atallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Jessica%20Koura"> Jessica Koura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the increase of demand on dietetic food and the need for more types of diet food, the production of dietetic food is increasing and improving. This demand on dietetic food has triggered us to study the market in which we found that Kishk (Lebanese dairy product) diet is not available. Production of a low fat product which is diet Kishk was our concern. A strategy was followed to choose the right idea that will satisfy the need of the market. The whole process was studied and explained thoroughly. The percentage of fat was found to be 32.52 % in regular Kishk and 3.84 % in the diet Kishk produced. The new product has the advantage to be high in protein, low in fat. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20and%20industrialization" title="design and industrialization">design and industrialization</a>, <a href="https://publications.waset.org/abstracts/search?q=dietetic" title=" dietetic"> dietetic</a>, <a href="https://publications.waset.org/abstracts/search?q=diet%20Kishk" title=" diet Kishk"> diet Kishk</a>, <a href="https://publications.waset.org/abstracts/search?q=fat" title=" fat"> fat</a> </p> <a href="https://publications.waset.org/abstracts/58410/design-of-a-dietetic-food-case-of-lebanese-kishk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58410.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">375</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">67</span> A Multi-Level Approach to Improve Sustainability Performances of Industrial Agglomerations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Innocenti">Patrick Innocenti</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20Montini"> Elias Montini</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Menato"> Silvia Menato</a>, <a href="https://publications.waset.org/abstracts/search?q=Marzio%20Sorlini"> Marzio Sorlini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Documented experiences of industrial symbiosis are always triggered and driven only by economic goals: environmental and (even rarely) social results are sometimes assessed and declared as effects of virtuous behaviours, but are merely casual and un-pursued side externalities. Even worse: all the symbiotic project candidates entailing economic loss for just one of the (also dozen) partners are simply stopped without considering the overall benefit for the whole partnership. The here-presented approach aims at providing methodologies and tools to effectively manage these situations and fostering the implementation of virtuous symbiotic investments in manufacturing aggregations for a more sustainable production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business%20model" title="business model">business model</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20symbiosis" title=" industrial symbiosis"> industrial symbiosis</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20agglomerations" title=" industrial agglomerations"> industrial agglomerations</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/62439/a-multi-level-approach-to-improve-sustainability-performances-of-industrial-agglomerations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62439.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">290</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> Proposal to Increase the Efficiency, Reliability and Safety of the Centre of Data Collection Management and Their Evaluation Using Cluster Solutions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martin%20Juhas">Martin Juhas</a>, <a href="https://publications.waset.org/abstracts/search?q=Bohuslava%20Juhasova"> Bohuslava Juhasova</a>, <a href="https://publications.waset.org/abstracts/search?q=Igor%20Halenar"> Igor Halenar</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrej%20Elias"> Andrej Elias</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article deals with the possibility of increasing efficiency, reliability and safety of the system for teledosimetric data collection management and their evaluation as a part of complex study for activity “Research of data collection, their measurement and evaluation with mobile and autonomous units” within project “Research of monitoring and evaluation of non-standard conditions in the area of nuclear power plants”.

The deposition conditions for production of Ni-W coatings have been optimized for peak performance of their electrocatalytic activity, namely hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). The corrosion behavior of the coatings were tested under working conditions of electrocatalysis (1M KOH). Electrocatalytic behaviours were tested by cyclic voltammetry and chrono-potentiometry techniques. Experimental results demonstrated that Ni-W coatings at low and high current densities (c. d.) showing superior performance for OER and HER respectively. The increased electrocatalytic activity for HER with increase of deposition c. d. was attributed to the phase structure, surface morphology and chemical composition of the coatings, confirmed by XRD, SEM and EDX analysis, respectively. The dependency of hardness and thickness of the coatings on HER and OER were examined, and results were discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrocatalytic%20behavior" title="electrocatalytic behavior">electrocatalytic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=HER" title=" HER"> HER</a>, <a href="https://publications.waset.org/abstracts/search?q=Ni-W%20alloy" title=" Ni-W alloy"> Ni-W alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=OER" title=" OER"> OER</a> </p> <a href="https://publications.waset.org/abstracts/17794/ni-w-alloy-coatings-a-promising-electrode-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17794.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">416</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">62</span> Vertical Distribution of Heavy Metals and Enrichment in Core Marine Sediments of East Malaysia by INAA and ICP-MS </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmadreza%20Ashraf">Ahmadreza Ashraf</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20Saion"> Elias Saion</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Gharib%20Shahi"> Elham Gharib Shahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Chee%20Kong%20Yap"> Chee Kong Yap</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Suhaimi%20Hamzah"> Mohd Suhaimi Hamzah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fifty-five core marine sediments from three locations at South China Sea and one location each at Sulu Sea and Sulawesi Sea of coastal East Malaysia was analyzed for heavy metals using Instrumental Neutron Activation Analysis and Inductively Coupled Plasma Mass Spectroscopy.

This interference is considered a serious problem in second language learning. Usually, the interference has been phonological. But the objective of this research is to explore how the target language interferes with the mother tongue. In the case of the Igbo language, it interferes with English mostly at the phonological level while English interferes with Igbo at the realm of vocabulary. The result is a new language \"Engligbo\" which is a hybrid of English and Igbo. The Igbo language spoken by about 25 million people is one of the three most prominent languages in Nigeria. This paper discusses the phenomenal Engligbo, and other implications for Igbo learners of English. The method of analysis is descriptive. A number of recommendations were made that would help teachers handle problems arising from such mutual interferences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reciprocal%20interferences" title="reciprocal interferences">reciprocal interferences</a>, <a href="https://publications.waset.org/abstracts/search?q=bilingualism" title=" bilingualism"> bilingualism</a>, <a href="https://publications.waset.org/abstracts/search?q=implications" title=" implications"> implications</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20pedagogy" title=" language pedagogy "> language pedagogy </a> </p> <a href="https://publications.waset.org/abstracts/3835/reciprocal-interferences-in-bilingual-english-igbo-speaking-society-the-implications-in-language-pedagogy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3835.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">59</span> Self Immolation and the Deactivation of State Necropower</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kate%20L.%20Yusi">Kate L.

In this paper, the writer seeks to focus on self-immolation by Tibetan monks and other activists against Chinese imperialism, its continuing ethnic cleansing of the Tibetan people, forced assimilation, and territorial occupation. Here, the main driving force is this question: what does self-immolation mean to a people who are forced to live in deathspace? In other words, if one is reduced to nothingness that their deaths (as is their lives) become insignificant, in what ways does the reclamation of death/dying become a “way out” of this state-imposed enclave of death? To answer these questions, the writer engages with and put in conversation the works of Achille Mbembe, Elias Cannetti, and Giorgio Agamben. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=necropolitics" title="necropolitics">necropolitics</a>, <a href="https://publications.waset.org/abstracts/search?q=self%20immolation" title=" self immolation"> self immolation</a>, <a href="https://publications.waset.org/abstracts/search?q=tibetan%20people" title=" tibetan people"> tibetan people</a>, <a href="https://publications.waset.org/abstracts/search?q=chinese%20imperialism" title=" chinese imperialism"> chinese imperialism</a> </p> <a href="https://publications.waset.org/abstracts/153517/self-immolation-and-the-deactivation-of-state-necropower" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153517.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">114</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">58</span> Microstructural Investigations of Metal Oxides Encapsulated Thermochromic Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Emirov">Yusuf Emirov</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdullatif%20Hakami"> Abdullatif Hakami</a>, <a href="https://publications.waset.org/abstracts/search?q=Prasanta%20K%20Biswas"> Prasanta K Biswas</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20K%20Stefanakos"> Elias K Stefanakos</a>, <a href="https://publications.waset.org/abstracts/search?q=Sesha%20S%20Srinivasan"> Sesha S Srinivasan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is aimed to develop microencapsulated thermochromic materials and the analysis of core-shell formation using high resolution electron microscopy.

The first group watched the video clips with full captions. The second group watched the same video clips with keyword captions. The control group watched the video clips without captions. After watching each clip, participants took a listening comprehension test. At the end of the experiment, participants completed a questionnaire to measure their perceptions about the use of captions and the video clips they watched. Results indicated that the full captioning group significantly outperformed both the keyword captioning and the no captioning group on the listening comprehension tests. However, this study did not find any significant difference between the keyword captioning group and the no captioning group.

Due to threshold structures commonly occurring in CRR models, the associated mathematical optimization problems have the significant characteristic of being strongly non-differentiable. In order to face this enormous task, the resolution method proposed adopts a smoothing strategy using a special C∞ differentiable class function. The final estimation solution is obtained by solving a sequence of differentiable subproblems which gradually approach the original conceptual problem. The use of this technique, called Hyperbolic Smoothing Method (HSM), makes possible the application of the most powerful minimization algorithms, and also allows for the main difficulties presented by the original CRR problem to be overcome. A set of computational experiments is presented for the purpose of illustrating both the reliability and the efficiency of the proposed approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rainfall-runoff%20models" title="rainfall-runoff models">rainfall-runoff models</a>, <a href="https://publications.waset.org/abstracts/search?q=automatic%20calibration" title=" automatic calibration"> automatic calibration</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperbolic%20smoothing%20method" title=" hyperbolic smoothing method"> hyperbolic smoothing method</a> </p> <a href="https://publications.waset.org/abstracts/123935/the-hyperbolic-smoothing-approach-for-automatic-calibration-of-rainfall-runoff-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123935.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">149</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> Maximizing Coverage with Mobile Crime Cameras in a Stochastic Spatiotemporal Bipartite Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%28Ted%29%20Edward%20Holmberg">(Ted) Edward Holmberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Abdelguerfi"> Mahdi Abdelguerfi</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20Ioup"> Elias Ioup</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research details a coverage measure for evaluating the effectiveness of observer node placements in a spatial bipartite network.

The HHDPA was previously synthesized and characterized by FT-IR, 1H NMR, 31P NMR spectroscopy and elemental analysis. The effects contact time, initial pH, initial metal concentration, aqueous/organic phase ratio, extractant concentration and temperature on the extraction process have been studied. An empirical modelling was performed by using a 25 full factorial design, and regression equation for extraction metals was determined from the data. The conventional log-log analysis of the extraction data reveals that ratios of extractant to extracted U(VI), Pu(IV) and Th(IV) are 1:1, 1:2 and 1:2, respectively. Thermodynamic parameters showed that the extraction process was exothermic heat and spontaneous. The obtained optimal parameters were applied to real efﬂuents containing uranium(VI), plutonium(IV) and thorium(IV) ions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solvent%20extraction" title="solvent extraction">solvent extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=uranium" title=" uranium"> uranium</a>, <a href="https://publications.waset.org/abstracts/search?q=plutonium" title=" plutonium"> plutonium</a>, <a href="https://publications.waset.org/abstracts/search?q=thorium" title=" thorium"> thorium</a>, <a href="https://publications.waset.org/abstracts/search?q=1-hydroxyhexadecylidene-1-1-diphosphonic%20acid" title=" 1-hydroxyhexadecylidene-1-1-diphosphonic acid"> 1-hydroxyhexadecylidene-1-1-diphosphonic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=aqueous%20solution" title=" aqueous solution"> aqueous solution</a> </p> <a href="https://publications.waset.org/abstracts/37851/the-solvent-extraction-of-uranium-plutonium-and-thorium-from-aqueous-solution-by-1-hydroxyhexadecylidene-11-diphosphonic-acid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37851.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">288</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> Microstructure Characterization on Silicon Carbide Formation from Natural Wood</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noor%20Leha%20Abdul%20Rahman">Noor Leha Abdul Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Koay%20Mei%20Hyie"> Koay Mei Hyie</a>, <a href="https://publications.waset.org/abstracts/search?q=Anizah%20Kalam"> Anizah Kalam</a>, <a href="https://publications.waset.org/abstracts/search?q=Husna%20Elias"> Husna Elias</a>, <a href="https://publications.waset.org/abstracts/search?q=Teng%20Wang%20Dung"> Teng Wang Dung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dark Red Meranti and Kapur, kinds of important type of wood in Malaysia were used as a precursor to fabricate porous silicon carbide. A carbon template is produced by pyrolysis at 850°C in an oxygen free atmosphere. The carbon template then further subjected to infiltration with silicon by silicon melt infiltration method. The infiltration process was carried out in tube furnace in argon flow at 1500°C, at two different holding time; 2 hours and 3 hours. Thermo gravimetric analysis was done to investigate the decomposition behavior of two species of plants. The resulting silicon carbide was characterized by XRD which was found the formation of silicon carbide and also excess silicon. The microstructure was characterized by scanning electron microscope (SEM) and the density was determined by the Archimedes method. An increase in holding time during infiltration will increased the density as well as formation of silicon carbide.

In this case, as it is accepted by the most of the researchers, there are outputs, which are produced by a DMU to be used as inputs in a future time. Those outputs are known as intermediates. The common models, in DDEA, do not take into account the shape of the distribution of those inputs, outputs or intermediates data, assuming that the distribution of the virtual value of them does not deviate from linearity. This weakness causes the limitation of the accuracy of the analytical power of the traditional DDEA models. In this paper, the authors, using the concept of piecewise linear inputs and outputs, propose an extended DDEA model. The proposed model increases the flexibility of the traditional DDEA models and improves the measurement of the dynamic performance of DMUs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dynamic%20Data%20Envelopment%20Analysis" title="Dynamic Data Envelopment Analysis">Dynamic Data Envelopment Analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=DDEA" title=" DDEA"> DDEA</a>, <a href="https://publications.waset.org/abstracts/search?q=piecewise%20linear%20inputs" title=" piecewise linear inputs"> piecewise linear inputs</a>, <a href="https://publications.waset.org/abstracts/search?q=piecewise%20linear%20outputs" title=" piecewise linear outputs"> piecewise linear outputs</a> </p> <a href="https://publications.waset.org/abstracts/86963/improving-the-analytical-power-of-dynamic-dea-models-by-the-consideration-of-the-shape-of-the-distribution-of-inputsoutputs-data-a-linear-piecewise-decomposition-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86963.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">161</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> Comparison of Transparent Nickel Doped Cobalt Sulfide and Platinum Counter Electrodes Used in Quasi-Solid State Dye Sensitized Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dimitra%20Sygkridou">Dimitra Sygkridou</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitrios%20Karageorgopoulos"> Dimitrios Karageorgopoulos</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20Stathatos"> Elias Stathatos</a>, <a href="https://publications.waset.org/abstracts/search?q=Evangelos%20Vitoratos"> Evangelos Vitoratos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transparent nickel doped cobalt sulfide was fabricated on a SnO2:F electrode and tested as an efficient electrocatalyst and as an alternative to the expensive platinum counter electrode. In order to investigate how this electrode could affect the electrical characteristics of a dye-sensitized solar cell, we manufactured cells with the same TiO2 photoanode sensitized with dye (N719) and employing the same quasi-solid electrolyte, altering only the counter electrode used. The cells were electrically and electrochemically characterized and it was observed that the ones with the Ni doped CoS2 outperformed the efficiency of the cells with the Pt counter electrode (3.76% and 3.44% respectively). Particularly, the higher efficiency of the cells with the Ni doped CoS2 counter electrode (CE) is mainly because of the enhanced photocurrent density which is attributed to the enhanced electrocatalytic ability of the CE and the low charge transfer resistance at the CE/electrolyte interface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nickel%20doped%20cobalt%20sulfide" title="nickel doped cobalt sulfide">nickel doped cobalt sulfide</a>, <a href="https://publications.waset.org/abstracts/search?q=counter%20electrodes" title=" counter electrodes"> counter electrodes</a>, <a href="https://publications.waset.org/abstracts/search?q=dye-sensitized%20solar%20cells" title=" dye-sensitized solar cells"> dye-sensitized solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=quasi-solid%20state%20electrolyte" title=" quasi-solid state electrolyte"> quasi-solid state electrolyte</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20organic-inorganic%20materials" title=" hybrid organic-inorganic materials"> hybrid organic-inorganic materials</a> </p> <a href="https://publications.waset.org/abstracts/29157/comparison-of-transparent-nickel-doped-cobalt-sulfide-and-platinum-counter-electrodes-used-in-quasi-solid-state-dye-sensitized-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29157.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">760</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> Holomorphic Prioritization of Sets within Decagram of Strategic Decision Making of POSM Using Operational Research (OR): Analytic Hierarchy Process (AHP) Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elias%20Ogutu%20Azariah%20Tembe">Elias Ogutu Azariah Tembe</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussain%20Abdullah%20Habib%20Al-Salamin"> Hussain Abdullah Habib Al-Salamin </a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is decagram of strategic decisions of operations and production/service management (POSM) within operational research (OR) which must collate, namely: design, inventory, quality, location, process and capacity, layout, scheduling, maintain ace, and supply chain.

Training networks on frequency features such as the Mel-Spectrogram or Cochleogram have been proven more effective and convenient than training on-time samples. In practical realizations, these features are created on a different processor and/or pre-computed and stored on disk, requiring additional efforts and making it difficult to experiment with different features. In this paper, we provide a PyTorch framework for creating various spectral features as well as time-frequency transformation and time-domain filter-banks using the built-in trainable conv1d() layer. This allows computing these features on the fly as part of a larger network and enabling easier experimentation with various combinations and parameters. Our work extends the work in the literature developed for that end: First, by adding more of these features and also by allowing the possibility of either starting from initialized kernels or training them from random values. The code is written as a template of classes and scripts that users may integrate into their own PyTorch classes or simply use as is and add more layers for various applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neural%20networks%20Mel-Spectrogram" title="neural networks Mel-Spectrogram">neural networks Mel-Spectrogram</a>, <a href="https://publications.waset.org/abstracts/search?q=chromagram" title=" chromagram"> chromagram</a>, <a href="https://publications.waset.org/abstracts/search?q=cochleogram" title=" cochleogram"> cochleogram</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20Fourrier%20transform" title=" discrete Fourrier transform"> discrete Fourrier transform</a>, <a href="https://publications.waset.org/abstracts/search?q=PyTorch%20conv1d%28%29" title=" PyTorch conv1d()"> PyTorch conv1d()</a> </p> <a href="https://publications.waset.org/abstracts/133529/1d-convolutional-networks-to-compute-mel-spectrogram-chromagram-and-cochleogram-for-audio-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133529.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">46</span> The Involvement of Viruses and Fungi in the Pathogenesis of Dental Infections</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wael%20Khalil">Wael Khalil</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20Rahal"> Elias Rahal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghassan%20Matar"> Ghassan Matar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tooth related infections or commonly named dental infections have been described as the most common causes of tooth loss in adults. These pathologies were mostly periodontitis, pericoronitis, and periapical infection. The involvement of various bacteria in the pathogenesis of these pathologies has been thoroughly mentioned and approved in the literature. However, the variability in the severity and prognosis of these lesions among patients suggests the association of other pathogens, like viruses and fungi, in the pathogenesis of these lesions. Several studies in the literature investigated the association of multiple viruses and fungi with the above-mentioned lesions, yet, a vast controversy was reached concerning this subject.Aim: Our study aims to fill the gap in the literature concerning the contribution of adenovirus, HPV-16, EBV, fungi, and candida in the pathogenesis of periodontitis, pericoronitis, and periapical infection. For this purpose, we utilized the quantitative PCR for pathogen detection in saliva, gingival, and lesions samples of involved subjects. Results: Some of these pathogens appeared to have an association with the investigated dental pathologies, while others showed no contribution to the pathogenesis of these lesions. Further investigation is required in order to identify the subtype of the involved pathogens in these tooth related oral pathology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=periodontitis" title="periodontitis">periodontitis</a>, <a href="https://publications.waset.org/abstracts/search?q=pericoronitis" title=" pericoronitis"> pericoronitis</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20abscess" title=" dental abscess"> dental abscess</a>, <a href="https://publications.waset.org/abstracts/search?q=PCR" title=" PCR"> PCR</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiology" title=" microbiology"> microbiology</a> </p> <a href="https://publications.waset.org/abstracts/149650/the-involvement-of-viruses-and-fungi-in-the-pathogenesis-of-dental-infections" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149650.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">99</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> A Low-Cost Air Quality Monitoring Internet of Things Platform</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christos%20Spandonidis">Christos Spandonidis</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefanos%20Tsantilas"> Stefanos Tsantilas</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20Sedikos"> Elias Sedikos</a>, <a href="https://publications.waset.org/abstracts/search?q=Nektarios%20Galiatsatos"> Nektarios Galiatsatos</a>, <a href="https://publications.waset.org/abstracts/search?q=Fotios%20Giannopoulos"> Fotios Giannopoulos</a>, <a href="https://publications.waset.org/abstracts/search?q=Panagiotis%20Papadopoulos"> Panagiotis Papadopoulos</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikolaos%20Demagos"> Nikolaos Demagos</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitrios%20Reppas"> Dimitrios Reppas</a>, <a href="https://publications.waset.org/abstracts/search?q=Christos%20Giordamlis"> Christos Giordamlis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present paper, a low cost, compact and modular Internet of Things (IoT) platform for air quality monitoring in urban areas is presented.

An electrochromic device consisting of polyaniline (PANI) has a redox-active gel electrolyte placed between two conducting transparent fluorine-doped tin oxide glass substrates. The redox-active composite gel is a mixture of different concentrations of aniline (monomer), a water-soluble polymer poly (vinyl alcohol), hydrochloric acid, and an oxidant. The EC device shows the color change from dark green to transparent for the applied potential between -0.5 V to +2.0 V. The coloration and decoloration of the ECs were tested for electrochemical behavior using techniques such as cyclic voltammetry (CV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS). The optical transparency of the EC devices was examined at two different biasing voltage conditions under UV-visible spectroscopic technique; the result showed 65% transmittance at 564 nm and zero transmittance when the cell was biased at 0.0 V and 2.0 V, the synthesized mol fraction gel was analyzed for surface morphology and structural properties by scanning electron microscopy and Fourier transformer spectroscopy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochromic" title="electrochromic">electrochromic</a>, <a href="https://publications.waset.org/abstracts/search?q=gel%20electrolyte" title=" gel electrolyte"> gel electrolyte</a>, <a href="https://publications.waset.org/abstracts/search?q=polyaniline" title=" polyaniline"> polyaniline</a>, <a href="https://publications.waset.org/abstracts/search?q=conducting%20polymer" title=" conducting polymer"> conducting polymer</a> </p> <a href="https://publications.waset.org/abstracts/136080/effect-of-gel-concentration-on-physical-properties-of-an-electrochromic-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136080.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">43</span> Social Work Profession in a Mirror of the Russian Immigrant Media in Israel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Khvorostianov">Natalia Khvorostianov</a>, <a href="https://publications.waset.org/abstracts/search?q=Nelly%20Elias"> Nelly Elias</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study seeks to analyze representation of social work in immigrant media, focusing on the case of online newspapers established by immigrants from the Former Soviet Union (FSU) in Israel. This immigrant population is particularly interesting because social work did not exist as a profession practiced in the USSR and hence most FSU immigrants arrive in Israel without a basic knowledge of the essence of social work, the services it provides and the logic behind its treatment methods. The sample of 37 items was built through a Google search of the Russian online newspapers and portals originated in Israel by using keywords such as “social worker,” “social work services” and the like. All items were analyzed by using qualitative content analysis. Principal analytical categories used for the analysis were: Assessment of social work services (negative, positive, neutral); social workers’ professionalism and effectiveness; goals and motives underlying their activity; cross-cultural contact with immigrants and methods used in working with immigrants. On this basis, four dominant images used to portray Israeli social work services and social workers were identified: Lack of professionalism, cultural gaps between FSU immigrants and Israeli social workers, repressive character of social work services and social workers’ involvement in corruption and crime. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FSU%20immigrants" title="FSU immigrants">FSU immigrants</a>, <a href="https://publications.waset.org/abstracts/search?q=immigrant%20media" title=" immigrant media"> immigrant media</a>, <a href="https://publications.waset.org/abstracts/search?q=media%20images" title=" media images"> media images</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20workers" title=" social workers"> social workers</a> </p> <a href="https://publications.waset.org/abstracts/33720/social-work-profession-in-a-mirror-of-the-russian-immigrant-media-in-israel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33720.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">357</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">42</span> Liquid-Liquid Extraction of Uranium(vi) from Aqueous Solution Using 1-Hydroxyalkylidene-1,1-Diphosphonic Acids </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Bouhoun%20Ali">M.

In this paper, we propose a tentative assignment for the shifts of those two ligands and their specific complexes with uranium(VI). We carried out the extraction of uranium(VI) by HHDPA and HDDPA from [carbon tetrachloride + 2-octanol (v/v: 90%/10%)] solutions. Various factors such as contact time, pH, organic/aqueous phase ratio and extractant concentration were considered. The optimum conditions obtained were: contact time= 20 min, organic/aqueous phase ratio = 1, pH value = 3.0 and extractant concentration = 0.3M. The extraction yields are more significant in the case of the HHDPA which is equipped with a hydrocarbon chain, longer than that of the HDDPA. Logarithmic plots of the uranium(VI) distribution ratio vs. pHeq and the extractant concentration showed that the ratio of extractant to extracted uranium(VI) (ligand/metal) is 2:1. The formula of the complex of uranium(VI) with the HHDPA and the DHDPA is UO2(H3L)2 (HHDPA and DHDPA are denoted as H4L). A spectroscopic analysis has showed that coordination of uranium(VI) takes place via oxygen atoms. <p class="card-text"><strong>Keywords:</strong> <a
