The CdS thin films were annealed in air, argon, hydrogen and nitrogen for 1 h at various temperatures (300, 350, 400, 450 and 500 °C). The changes in optical and electrical properties of annealed treated CdS thin films were analyzed. The results showed that, the band-gap and resistivity depend on the post-deposition annealing atmosphere and temperatures. Thus, it was found that these properties of the films, were found to be affected by various processes with opposite effects, some beneficial and others unfavorable. The energy gap and resistivity for different annealing atmospheres was seen to oscillate by thermal annealing. Recrystallization, oxidation, surface passivation, sublimation and materials evaporation were found the main factors of the heat-treatment process responsible for this oscillating behavior. Annealing over 400 °C was seen to degrade the optical and electrical properties of the film. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cds" title="cds">cds</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20films" title=" thin films"> thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=annealing" title=" annealing"> annealing</a>, <a href="https://publications.waset.org/abstracts/search?q=optical" title=" optical"> optical</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20properties" title=" electrical properties"> electrical properties</a> </p> <a href="https://publications.waset.org/abstracts/31251/characterization-of-chemically-deposited-cds-thin-films-annealed-in-different-atmospheres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31251.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">510</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">335</span> First-Principles Investigation of the Structural and Electronic Properties of Mg1-xBixO</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20P.%20Abdel%20Rahim">G.

The calculations were performed using the first-principles pseudo-potential method within the framework of spin density functional theory (DFT). Our calculations predict that for Bi concentrations greater than ~70%, the WZ structure is more favorable than the NaCl one and that for x = 0 (pure MgO), x = 0.25 and x = 0.50 of Bi concentration the NaCl structure is more favorable than the WZ one. For x = 0.75 of Bi, a transition from wurtzite towards NaCl is possible, when the pressure is about 22 GPa. Also It has been observed the crystal lattice constant closely follows Vegard’s law, that the bulk modulus and the cohesion energy decrease with the concentration x of Bi. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DFT" title="DFT">DFT</a>, <a href="https://publications.waset.org/abstracts/search?q=Mg1-xBixO" title=" Mg1-xBixO"> Mg1-xBixO</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudo-potential" title=" pseudo-potential"> pseudo-potential</a>, <a href="https://publications.waset.org/abstracts/search?q=rock-salt" title=" rock-salt"> rock-salt</a>, <a href="https://publications.waset.org/abstracts/search?q=wurtzite" title=" wurtzite"> wurtzite</a> </p> <a href="https://publications.waset.org/abstracts/24781/first-principles-investigation-of-the-structural-and-electronic-properties-of-mg1-xbixo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24781.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">525</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">334</span> Comparing ITV Definitions From 4D CT-PET and Breath-Hold Technique with Abdominal Compression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20D.%20Esposito">R.

Extending the ignition delay to promote the premixing, has been recognized as one of the key factor to achieve PPC. Fuels with high octane number have been proven to be a good candidates to extend the ignition delay. In this work, E85 (85% ethanol) has been used as a PPC fuel. The aim of this work was to investigate a suitable injection strategy for PPC combustion fueled with E85 in a single-cylinder heavy-duty engine. Single and double injection strategy were applied with different injection timing and the ratio between different injection pulses was varied. The performance and emission were investigated at low load. The results show that the double injection strategy should be preferred for PPC fueled with E85 due to low emissions and high efficiency, while keeping the pressure raise rate at very low levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=E85" title="E85">E85</a>, <a href="https://publications.waset.org/abstracts/search?q=partially%20premixed%20combustion" title=" partially premixed combustion"> partially premixed combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=injection%20strategy" title=" injection strategy"> injection strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20and%20emission" title=" performance and emission"> performance and emission</a> </p> <a href="https://publications.waset.org/abstracts/85102/effect-of-injection-strategy-on-the-performance-and-emission-of-e85-in-a-heavy-duty-engine-under-partially-premixed-combustion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85102.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">177</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">332</span> An Evaluation Model for Enhancing Flexibility in Production Systems through Additive Manufacturing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Angela%20Luft">Angela Luft</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Bremen"> Sebastian Bremen</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolae%20Balc"> Nicolae Balc</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Additive manufacturing processes have entered large parts of the industry and their range of application have progressed and grown significantly in the course of time. A major advantage of additive manufacturing is the innate flexibility of the machines. This corelates with the ongoing demand of creating highly flexible production environments. However, the potential of additive manufacturing technologies to enhance the flexibility of production systems has not yet been truly considered and quantified in a systematic way. In order to determine the potential of additive manufacturing technologies with regards to the strategic flexibility design in production systems, an integrated evaluation model has been developed, that allows for the simultaneous consideration of both conventional as well as additive production resources. With the described model, an operational scope of action can be identified and quantified in terms of mix and volume flexibility, process complexity, and machine capacity that goes beyond the current cost-oriented approaches and offers a much broader and more holistic view on the potential of additive manufacturing. A respective evaluation model is presented this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=capacity%20planning" title=" capacity planning"> capacity planning</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20systems" title=" production systems"> production systems</a>, <a href="https://publications.waset.org/abstracts/search?q=strategic%20production%20planning" title=" strategic production planning"> strategic production planning</a>, <a href="https://publications.waset.org/abstracts/search?q=flexibility%20enhancement" title=" flexibility enhancement"> flexibility enhancement</a> </p> <a href="https://publications.waset.org/abstracts/149112/an-evaluation-model-for-enhancing-flexibility-in-production-systems-through-additive-manufacturing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149112.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">157</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">331</span> Cultural Studies in the Immigration Movements: Memories and Social Collectives </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Eugenia%20Peltzer">María Eugenia Peltzer</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Estela%20Rodr%C3%ADguez"> María Estela Rodríguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work presents an approach to the cultural aspects of the Immigrants as part of the Cultural Intangible Heritage of Argentina. The intangible cultural heritage consists of the manifestations, practices, uses, representations, expressions, knowledge, techniques and cultural spaces that communities and groups recognize as an integral part of their cultural heritage. This heritage generates feelings of identity and establishes links with the collective memory, as well as being transmitted and recreated over time according to its environment, its interaction with nature and its history contributing to promote respect for cultural diversity and Human creativity. The Immigrants brings together those who came from other lands and their descendants, thus maintaining their traditions through time and linking the members of each cultural group with a strong sense of belonging through a communicative and effective process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural" title="cultural">cultural</a>, <a href="https://publications.waset.org/abstracts/search?q=immigration" title=" immigration"> immigration</a>, <a href="https://publications.waset.org/abstracts/search?q=memories" title=" memories"> memories</a>, <a href="https://publications.waset.org/abstracts/search?q=social" title=" social"> social</a> </p> <a href="https://publications.waset.org/abstracts/64279/cultural-studies-in-the-immigration-movements-memories-and-social-collectives" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64279.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">438</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">330</span> Temperature-Dependent Structural Characterization of Type-II Dirac Semi-Metal nite₂ From Bulk to Exfoliated Thin Flakes Using Raman Spectroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minna%20Theres%20James">Minna Theres James</a>, <a href="https://publications.waset.org/abstracts/search?q=Nirmal%20K%20Sebastian"> Nirmal K Sebastian</a>, <a href="https://publications.waset.org/abstracts/search?q=Shoubhik%20Mandal"> Shoubhik Mandal</a>, <a href="https://publications.waset.org/abstracts/search?q=Pramita%20Mishra"> Pramita Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=R%20Ganesan"> R Ganesan</a>, <a href="https://publications.waset.org/abstracts/search?q=P%20S%20Anil%20Kumar"> P S Anil Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We report the temperature-dependent evolution of Raman spectra of type-II Dirac semimetal (DSM) NiTe2 (001) in the form of bulk single crystal and a nanoflake (200 nm thick) for the first time. A physical model that can quantitatively explain the evolution of out of plane A1g and in-plane E1g Raman modes is used. The non-linear variation of peak positions of the Raman modes with temperature is explained by anharmonic three-phonon and four-phonon processes along with thermal expansion of the lattice. We also observe prominent effect of electron-phonon coupling from the variation of FWHM of the peaks with temperature, indicating the metallicity of the samples. Raman mode E1 1g corresponding to an in plane vibration disappears on decreasing the thickness from bulk to nanoflake. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=raman%20spectroscopy" title="raman spectroscopy">raman spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=type%202%20dirac%20semimetal" title=" type 2 dirac semimetal"> type 2 dirac semimetal</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel%20telluride" title=" nickel telluride"> nickel telluride</a>, <a href="https://publications.waset.org/abstracts/search?q=phonon-phonon%20coupling" title=" phonon-phonon coupling"> phonon-phonon coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=electron%20phonon%20coupling" title=" electron phonon coupling"> electron phonon coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=transition%20metal%20dichalcogonide" title=" transition metal dichalcogonide"> transition metal dichalcogonide</a> </p> <a href="https://publications.waset.org/abstracts/148958/temperature-dependent-structural-characterization-of-type-ii-dirac-semi-metal-nite2-from-bulk-to-exfoliated-thin-flakes-using-raman-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148958.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">329</span> The Gender Perspective Applied to the Analysis of Occupational Accidents </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Del%20Carmen%20Pardo%20Ferreira">María Del Carmen Pardo Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernando%20Rodriguez%20Cortes"> Fernando Rodriguez Cortes</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Carlos%20Rubio%20Romero"> Juan Carlos Rubio Romero</a> </p> <p class="card-text"><strong>Abstract:</strong></p> According to the International Labor Organization, every day there is more presence of women in the labor market although inequality between women and men persists in world labor markets.

But in literature, one can´t find any quantitative approach for valuing the usage of a DT or DPF in AM. Out of this fact, such an approach will be developed within this paper in order to further promote or dissuade the usage of these concepts. The focus is set on the production as an early lifecycle phase, which means that the AM-production process gets analyzed regarding the potential advantages of using DPF in AM. These advantages are transferred to a monetary value with this approach. By calculating the costs of the DPF, an overall monetary value is a result. Thereon a tool, based on a simulation environment is constructed, where the algorithms are transformed into a program. The results of applying this tool show that an overall value of 20,81 € for the DPF can be realized for one special use case. For the future application of the DPF there is the recommendation to integrate especially sustainable information because out of this, a higher value of the DPF can be expected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20concept%20costs" title=" digital concept costs"> digital concept costs</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20part%20file" title=" digital part file"> digital part file</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20twin" title=" digital twin"> digital twin</a>, <a href="https://publications.waset.org/abstracts/search?q=monetary%20value%20estimation" title=" monetary value estimation"> monetary value estimation</a> </p> <a href="https://publications.waset.org/abstracts/133143/method-for-evaluating-the-monetary-value-of-a-customized-version-of-the-digital-twin-for-the-additive-manufacturing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133143.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">200</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">326</span> Assessment of Modern RANS Models for the C3X Vane Film Cooling Prediction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mikhail%20Gritskevich">Mikhail Gritskevich</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Hohenstein"> Sebastian Hohenstein</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper presents the results of a detailed assessment of several modern Reynolds Averaged Navier-Stokes (RANS) turbulence models for prediction of C3X vane film cooling at various injection regimes.

It is shown that all the considered models face with a problem in prediction of the adiabatic effectiveness in the vicinity of the cooling holes; however, accounting for the Reynolds stress anisotropy within the EARSM model noticeably increases the solution accuracy.

However, the most advanced 3D scanners in the market that capture topology and texture at the same time, and are specifically made for this purpose, don’t deliver the accuracy that is needed for scientific research. In the last three years, we have developed a method that combines the use of Metrologic grade laser scans, that allows us to work with a high accuracy topology up to 15 times more precise and combine this mesh with a texture obtained from high definition photogrammetry with up to 100 times more pixel concentrations. The result is an accurate digitalization that promotes heritage preservation, scientific study, high detail reproduction, and digital restoration, among others. In Chile, we have already performed 478 digitalizations of high-value heritage pieces and compared the results with up to five different digitalization methods; the results obtained show a considerable better dimensional accuracy and texture resolution.

Pt5Gd represented higher HER activities than polycrystalline Pt (Pt(pc)) by means of the surface strain effects. The model of the equivalent electric circuit to fit the impedance data under the RDE configurations is developed. To investigate the relative reaction contribution, the ratio of the charge transfer reactions of the Volmer-Heyrovsky and Volmer-Tafel pathways on Pt and Pt5Gd electrodes is determined. The ratio remains comparably similar in acidic media, but it changes in alkaline media with Volmer–Heyrovsky pathway dominating. This combined approach of EIS and RDE can help to study the electrolyte effects and other essential reactions for electrocatalysis in future work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20evolution%20reaction" title="hydrogen evolution reaction">hydrogen evolution reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20impedance%20spectroscopy" title=" electrochemical impedance spectroscopy"> electrochemical impedance spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrodynamic%20methods" title=" hydrodynamic methods"> hydrodynamic methods</a>, <a href="https://publications.waset.org/abstracts/search?q=electrocatalysis" title=" electrocatalysis"> electrocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20interface" title=" electrochemical interface"> electrochemical interface</a> </p> <a href="https://publications.waset.org/abstracts/163419/combining-impedance-and-hydrodynamic-methods-toward-hydrogen-evolution-reaction-to-characterize-ptpc-pt5gd-and-nanostructure-pd-electrocatalyst" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163419.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">83</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">320</span> Evaluating Performance of an Anomaly Detection Module with Artificial Neural Network Implementation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edward%20Guill%C3%A9n">Edward Guillén</a>, <a href="https://publications.waset.org/abstracts/search?q=Jhordany%20Rodriguez"> Jhordany Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafael%20P%C3%A1ez"> Rafael Páez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Anomaly detection techniques have been focused on two main components: data extraction and selection and the second one is the analysis performed over the obtained data.

Naturally released into the environment through the weathering and erosion of sulphides mineral, some activities such as mining, the use of pesticides or wood preservatives potentially increase the concentration of arsenic in air, water, and soil. The natural arsenic release of a geological material is a threat to the world's drinking water sources. In aqueous phase is found in inorganic form, as arsenate and arsenite mainly, the contamination of groundwater by salts of this element originates what is known as endemic regional hydroarsenicism. The International Agency for Research on Cancer (IARC) categorizes the inorganic As within group I, as a substance with proven carcinogenic action for humans. It has been found the presence of As in groundwater in several countries such as Argentina, Mexico, Bangladesh, Canada and the United States. Regarding the concentration of arsenic in drinking water according to the World Health Organization (WHO) and the Environmental Protection Agency (EPA) establish maximum concentrations of 10 μg L⁻¹. In Mexico, in some states as Hidalgo, Morelos and Michoacán concentrations of arsenic have been found in bodies of water around 1000 μg L⁻¹, a concentration that is well above what is allowed by Mexican regulations with the NOM-127- SSA1-1994 that establishes a limit of 25 μg L⁻¹. Given this problem in Mexico, this research proposes the use of a natural Mexican zeolite (clinoptilolite type) native to the district of Etla in the central valley region of Oaxaca, as an adsorbent for the removal of arsenic. The zeolite was subjected to a conditioning with iron oxide by the precipitation-impregnation method with 0.5 M iron nitrate solution, in order to increase the natural adsorption capacity of this material. The removal of arsenic was carried out in a column with a fixed bed of conditioned zeolite, since it combines the advantages of a conventional filter with those of a natural adsorbent medium, providing a continuous treatment, of low cost and relatively easy to operate, for its implementation in marginalized areas. The zeolite was characterized by XRD, SEM/EDS, and FTIR before and after the arsenic adsorption tests, the results showed that the modification methods used are adequate to prepare adsorbent materials since it does not modify its structure, the results showed that with a particle size of 1.18 mm, an initial concentration of As (V) ions of 1 ppm, a pH of 7 and at room temperature, a removal of 98.7% was obtained with an adsorption capacity of 260 μg As g⁻¹ zeolite. The results obtained indicated that the conditioned zeolite is favorable for the elimination of arsenate in water containing up to 1000 μg As L⁻¹ and could be suitable for removing arsenate from pits of water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=arsenic" title=" arsenic"> arsenic</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20conditioning" title=" iron conditioning"> iron conditioning</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20zeolite" title=" natural zeolite"> natural zeolite</a> </p> <a href="https://publications.waset.org/abstracts/89747/natural-mexican-zeolite-modified-with-iron-to-remove-arsenic-ions-from-water-sources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89747.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">172</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">318</span> Reflections on the Role of Cultural Identity in a Bilingual Education Program</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lina%20Tenjo">Lina Tenjo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilba%20Rodr%C3%ADguez"> Ilba Rodríguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The role of cultural identity in bilingual programs has been barely discussed in regards to SLA. This research focuses on providing relevant information that helps in having more knowledge about the experiences that an elementary student has during the second language learning process in a bilingual program within a multicultural context. This study explores the experience of 18 students in a dual language program, in a public elementary school in Northern Virginia, USA. It examines their dual language experience and the different ways this experience contributes to the formation of their cultural identity. The findings were studied with the purpose of determining the relationship between participants and certain aspects of cultural identity in a multicultural context. The reflections that originate from the voices of children are the key source that helps us to better understand the particular needs that young learners have during their participation in a DLP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acculturation" title="acculturation">acculturation</a>, <a href="https://publications.waset.org/abstracts/search?q=bilingual%20education" title=" bilingual education"> bilingual education</a>, <a href="https://publications.waset.org/abstracts/search?q=culture" title=" culture"> culture</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20language%20program" title=" dual language program"> dual language program</a>, <a href="https://publications.waset.org/abstracts/search?q=identity" title=" identity"> identity</a>, <a href="https://publications.waset.org/abstracts/search?q=second%20language%20acquisition" title=" second language acquisition"> second language acquisition</a> </p> <a href="https://publications.waset.org/abstracts/59189/reflections-on-the-role-of-cultural-identity-in-a-bilingual-education-program" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59189.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">339</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">317</span> Complexity in Managing Higher Education Institutions in Mexico: A System Dynamics Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Carlos%20Rodr%C3%ADguez">José Carlos Rodríguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20G%C3%B3mez"> Mario Gómez</a>, <a href="https://publications.waset.org/abstracts/search?q=Medardo%20Serna"> Medardo Serna</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper analyses managing higher education institutions in emerging economies.

To match the first requirement, the most popular RL libraries advocate for highly modular agent composability, which facilitates experimentation and development. To solve challenging environments within reasonable time frames, scaling RL to large sampling and computing resources has proved a successful strategy. However, this capability has been so far difficult to combine with modularity. In this work, we explore design choices to allow agent composability both at a local and distributed level of execution. We propose a versatile approach that allows the definition of RL agents at different scales through independent, reusable components. We demonstrate experimentally that our design choices allow us to reproduce classical benchmarks, explore multiple distributed architectures, and solve novel and complex environments while giving full control to the user in the agent definition and training scheme definition. We believe this work can provide useful insights to the next generation of RL libraries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20reinforcement%20learning" title="deep reinforcement learning">deep reinforcement learning</a>, <a href="https://publications.waset.org/abstracts/search?q=Python" title=" Python"> Python</a>, <a href="https://publications.waset.org/abstracts/search?q=PyTorch" title=" PyTorch"> PyTorch</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20training" title=" distributed training"> distributed training</a>, <a href="https://publications.waset.org/abstracts/search?q=modularity" title=" modularity"> modularity</a>, <a href="https://publications.waset.org/abstracts/search?q=library" title=" library"> library</a> </p> <a href="https://publications.waset.org/abstracts/167759/integrating-distributed-architectures-in-highly-modular-reinforcement-learning-libraries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167759.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">83</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">314</span> Production of Bioethanol through Hydrolysis of Agro-Industrial Banana Crop Residues</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S%C3%A1nchez%20Acu%C3%B1a">Sánchez Acuña</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Camilo"> Juan Camilo</a>, <a href="https://publications.waset.org/abstracts/search?q=Granados%20G%C3%B3mez"> Granados Gómez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mildred%20Magaly"> Mildred Magaly</a>, <a href="https://publications.waset.org/abstracts/search?q=Navarrete%20Rodr%C3%ADguez"> Navarrete Rodríguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Luisa%20Fernanda"> Luisa Fernanda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, the main biofuels source production as bioethanol is food crops.

Based on the data, it can be inferred that monolingual instruction in either Filipino or English had a stronger effect on the students’ literacy skills compared to bilingual instruction. Moreover, mother tongue-based instruction, as compared to second-language instruction, had stronger effect on the preschoolers’ literacy skills. Such results have implications not only for mother tongue-based (MTB) but also for English as a second language (ESL) instruction in the country <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bilingualism" title="bilingualism">bilingualism</a>, <a href="https://publications.waset.org/abstracts/search?q=effects" title="effects">effects</a>, <a href="https://publications.waset.org/abstracts/search?q=monolingual" title=" monolingual"> monolingual</a>, <a href="https://publications.waset.org/abstracts/search?q=function" title="function">function</a>, <a href="https://publications.waset.org/abstracts/search?q=multilingual" title=" multilingual"> multilingual</a>, <a href="https://publications.waset.org/abstracts/search?q=mother%20tongue" title=" mother tongue"> mother tongue</a> </p> <a href="https://publications.waset.org/abstracts/120430/effects-of-bilingual-education-in-the-teaching-and-learning-practices-in-the-continuous-improvement-and-development-of-k12-program" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120430.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">312</span> Preschool Story Retelling: Actions and Verb Use</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eva%20Nwokah">Eva Nwokah</a>, <a href="https://publications.waset.org/abstracts/search?q=Casey%20Taliancich-Klinger"> Casey Taliancich-Klinger</a>, <a href="https://publications.waset.org/abstracts/search?q=Lauren%20Luna"> Lauren Luna</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Rodriguez"> Sarah Rodriguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Story-retelling is a technique frequently used to assess children’s language skills and support their development of narratives. Fourteen preschool children listened to one of two stories from the wordless, illustrated Frog book series and then retold the story using the pictures. A comparison of three verb types (action, mental and other) in the original story model, and children's verb use in their retold stories revealed the salience of action events. The children's stories contained a similar proportion of verb types to the original story. However, the action verbs they used were rarely those they had heard in the original. The implications for the process of lexical encoding and narrative recall are discussed, as well as suggestions for the use of wordless picture books and the language teaching of new verbs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=story%20re-telling" title="story re-telling">story re-telling</a>, <a href="https://publications.waset.org/abstracts/search?q=verb%20use" title=" verb use"> verb use</a>, <a href="https://publications.waset.org/abstracts/search?q=preschool%20language" title=" preschool language"> preschool language</a>, <a href="https://publications.waset.org/abstracts/search?q=wordless%20picture%20books" title=" wordless picture books"> wordless picture books</a> </p> <a href="https://publications.waset.org/abstracts/74836/preschool-story-retelling-actions-and-verb-use" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74836.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">270</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">311</span> Kinetic Study of Thermal Degradation of a Lignin Nanoparticle-Reinforced Phenolic Foam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20C.%20Dom%C3%ADnguez">Juan C.

The average values for five heating rates of the mean activation energies obtained were: 99.1, 128.2, and 144.0 kJ.mol-1 for the phenolic foam, 109.5, 113.3, and 153.0 kJ.mol-1 for the lignin reinforcement, and 82.1, 106.9, and 124.4 kJ. mol-1 for the lignin reinforced phenolic foam. The standard deviation ranges calculated for each sample were 1.27-8.85, 2.22-12.82, and 3.17-8.11 kJ.mol-1 for the phenolic foam, lignin and the reinforced foam, respectively. The DAEM model showed low mean square errors (< 1x10-5), proving that is a suitable model to study the kinetics of thermal degradation of the foams and the reinforcement. <p
