The goal of this work is to study the modification of the optoelectronic and structural properties of Lithium incorporation. The increase of Li doping in PbS thin films leads to an increase of band gap in the range of 1.4-2.3, consequently, quantum size effect becomes pronounced in the Li-doped PbS films, which lead to a significant enhancement in the optical band gap. Doping shows influence in the film growth and results in a reduction of crystallite size from 30 to 14 nm. The refractive index was calculated and a relationship with dielectric constant was investigated. The dc conductivities of Li-doped and undoped samples were measured in the temperature range 290-340K, the conductivity increase with increase of Lithium content in the PbS films. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=doping" title="doping">doping</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20confinement" title=" quantum confinement"> quantum confinement</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20band%20gap" title=" optical band gap"> optical band gap</a>, <a href="https://publications.waset.org/abstracts/search?q=PbS" title=" PbS"> PbS</a> </p> <a href="https://publications.waset.org/abstracts/58519/structural-and-optoelectronic-properties-of-monovalent-cation-doping-pbs-thin-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58519.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">383</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> Prevalence of Human Papillomavirus in Squamous Intraepithelial Lesions and Cervical Cancer in Women of the North of Chihuahua, Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Estefania%20Ponce-Amaya">Estefania Ponce-Amaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Lidia%20Arellano-Ortiz"> Ana Lidia Arellano-Ortiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Diaz-Hernandez"> Cecilia Diaz-Hernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Alberto%20Lopez-Diaz"> Jose Alberto Lopez-Diaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20De%20La%20Mora-Covarrubias"> Antonio De La Mora-Covarrubias</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Lucia%20Vargas-Requena"> Claudia Lucia Vargas-Requena</a>, <a href="https://publications.waset.org/abstracts/search?q=Mauricio%20Salcedo-Vargas"> Mauricio Salcedo-Vargas</a>, <a href="https://publications.waset.org/abstracts/search?q=Florinda%20Jimenez-Vega"> Florinda Jimenez-Vega </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cervical Cancer (CC) is the second leading cause of death among women worldwide and it had been associated with a persistent infection of human papillomavirus (HPV). The goal of the current study was to identify the prevalence of HPV infection in women with abnormal Pap smear who were attended at Dysplasia Clinic of Ciudad Juarez, Mexico. Methods: Cervical samples from 146 patients, who attended the Colposcopy Clinic at Sanitary Jurisdiction II of Cd Juarez, were collected for histopathology and molecular study. DNA was isolated for the HPV detection by Polymerase Chain Reaction (PCR) using MY09/011 and GP5/6 primers. The associated risk factors were assessed by a questionnaire. The statistical analysis was performed by ANOVA, using EpiINFO V7 software. Results: HPV infection was present in 142 patients (97.3 %). The prevalence of HPV infection was distributed in a 96% of all evaluated groups, low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HISIL) and CC. We found a statistical significance (α = <0.05) between gestation and number of births as risk factors. The median values showed an ascending tend according with the lesion progression. However, CC showed a statistically significant difference with respect to the pre-carcinogenic stages. Conclusions: In these Mexican patients exists a high prevalence of HPV infection, and for that reason, we are studying the most prevalent HPV genotypes in this population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cervical%20cancer" title="cervical cancer">cervical cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=HPV" title=" HPV"> HPV</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence%20hpv" title=" prevalence hpv"> prevalence hpv</a>, <a href="https://publications.waset.org/abstracts/search?q=squamous%20intraepithelial%20lesion" title=" squamous intraepithelial lesion"> squamous intraepithelial lesion</a> </p> <a href="https://publications.waset.org/abstracts/79528/prevalence-of-human-papillomavirus-in-squamous-intraepithelial-lesions-and-cervical-cancer-in-women-of-the-north-of-chihuahua-mexico" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79528.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">320</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">61</span> Low Temperature Solution Processed Solar Cell Based on ITO/PbS/PbS:Bi3+ Heterojunction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Chavez"> M.

Our approach is an extension of the job shop problem with transportation delay, where the location of the machines is selected among possible sites. The model minimizes the makespan, using the short processing times rule with two algorithms; the first one considers all the permutations for the location of machines, and the second only a heuristic to select some specific permutations that reduces computational time.

Which are the reasons of that? Some of the reason maybe could be embedded in how KM is demanded (usefulness, priority, experts, a definition of KM) vs the importance and resources that the organizations afford (budget, responsible of a specific area of KM, intangibility). Many organizations “claim” the importance of Knowledge Management but thhese demands are not reflecting these claims in their future actions. With another’s tools or managements ideas the organizations put the economics and human resources to work. Why it´s not occur in KM?

Comparative analyses of world migration statistics as methodology offer the insight into the position of women in labor market around world. There are different forms of youth debris in contemporary world. The main problems are illegal migration, feminization of poverty, kidnapping the girls in Nigeria, femicides in Juarez and Mexico. Illegal migrations involve forced labor, rape and prostitution. Transgender youth share ideas through the online media (anti-bullying videos) and develop their own styles such as anarcho-punk, rave, or rock. Therefore, the stronger gender equality laws and laws for protection of women on work should be enforced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hyperfeminisation" title="hyperfeminisation">hyperfeminisation</a>, <a href="https://publications.waset.org/abstracts/search?q=rape" title=" rape"> rape</a>, <a href="https://publications.waset.org/abstracts/search?q=gangs%20of%20girls" title=" gangs of girls"> gangs of girls</a>, <a href="https://publications.waset.org/abstracts/search?q=rent%20boys%20masculinities" title=" rent boys masculinities"> rent boys masculinities</a>, <a href="https://publications.waset.org/abstracts/search?q=Varo%C3%A7%20in%20Istanbul" title=" Varoç in Istanbul"> Varoç in Istanbul</a>, <a href="https://publications.waset.org/abstracts/search?q=forced%20labor" title=" forced labor"> forced labor</a>, <a href="https://publications.waset.org/abstracts/search?q=rape%20and%20prostitution" title=" rape and prostitution"> rape and prostitution</a>, <a href="https://publications.waset.org/abstracts/search?q=illegal%20emigrations" title=" illegal emigrations"> illegal emigrations</a> </p> <a href="https://publications.waset.org/abstracts/78582/gender-dimension-of-migrations-influenced-by-genocide-and-feminicides-around-the-globe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78582.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">257</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">55</span> Material Failure Process Simulation by Improved Finite Elements with Embedded Discontinuities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gelacio%20Ju%C3%A1rez-Luna">Gelacio Juárez-Luna</a>, <a href="https://publications.waset.org/abstracts/search?q=Gustavo%20Ayala"> Gustavo Ayala</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaime%20Retama-Velasco"> Jaime Retama-Velasco</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper shows the advantages of the material failure process simulation by improve finite elements with embedded discontinuities, using a new definition of traction vector, dependent on the discontinuity length and the angle. Particularly, two families of this kind of elements are compared: kinematically optimal symmetric and statically and kinematically optimal non-symmetric. The constitutive model to describe the behavior of the material in the symmetric formulation is a traction-displacement jump relationship equipped with softening after reaching the failure surface. To show the validity of this symmetric formulation, representative numerical examples illustrating the performance of the proposed formulation are presented. It is shown that the non-symmetric family may over or underestimate the energy required to create a discontinuity, as this effect is related with the total length of the discontinuity, fact that is not noticed when the discontinuity path is a straight line. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=variational%20formulation" title="variational formulation">variational formulation</a>, <a href="https://publications.waset.org/abstracts/search?q=strong%20discontinuity" title=" strong discontinuity"> strong discontinuity</a>, <a href="https://publications.waset.org/abstracts/search?q=embedded%20discontinuities" title=" embedded discontinuities"> embedded discontinuities</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20localization" title=" strain localization "> strain localization </a> </p> <a href="https://publications.waset.org/abstracts/7919/material-failure-process-simulation-by-improved-finite-elements-with-embedded-discontinuities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7919.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">781</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> Forecasting the Volatility of Geophysical Time Series with Stochastic Volatility Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20C.%20Mariani">Maria C.

A stochastic technique with time-varying parameters is used to forecast the volatility of data arising in geophysics. In this study, the volatility is defined as a logarithmic first-order autoregressive process. We observe that the inclusion of log-volatility into the time-varying parameter estimation significantly improves forecasting which is facilitated via maximum likelihood estimation. This allows us to conclude that the estimation algorithm for the corresponding one-step-ahead suggested volatility (with ±2 standard prediction errors) is very feasible since it possesses good convergence properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Augmented%20Dickey%20Fuller%20Test" title="Augmented Dickey Fuller Test">Augmented Dickey Fuller Test</a>, <a href="https://publications.waset.org/abstracts/search?q=geophysical%20time%20series" title=" geophysical time series"> geophysical time series</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20likelihood%20estimation" title=" maximum likelihood estimation"> maximum likelihood estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20volatility%20model" title=" stochastic volatility model"> stochastic volatility model</a> </p> <a href="https://publications.waset.org/abstracts/75110/forecasting-the-volatility-of-geophysical-time-series-with-stochastic-volatility-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75110.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">315</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">53</span> Different Levels of Mixed Reality: Mixed Reality as a Tool to Change the Visitor's Experience in the Museum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hector%20Valverde%20Mart%C3%ADnez">Hector Valverde Martínez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this text, the application possibilities of developments in MR are explored as an element within the museographic space that affects the visitor-museum relationship to satisfy the needs of knowledge and recreation that visitors have to improve the experience.

In this work, we show cosmology, from a perspective that can provide some proposals to help develop SMB in Mexico. We start from the belief that, in a complex world, the solutions to problems must nurture from different approaches. In order to be able to do this, we need to change our point of reference and use theoretical proposals and methodologies that came from other disciplines; in this case, we will try to show that between philosophy and administration exist dialogs that need to be incentivized. The work is structured in three parts. In the first one, we create a description of cosmology and how it could be applied to business. In the second, we show some of the most common problems that the SMB suffer from and in the third, we present a proposal of how cosmology can help improve the development. Finally, we concluded that better understanding of real needs, integration of knowledge at large scale and using information technologies within the cosmology framework presentment could make a difference. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=harmonic%20fusion" title="harmonic fusion">harmonic fusion</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20sustainability" title=" national sustainability"> national sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20management" title=" financial management"> financial management</a>, <a href="https://publications.waset.org/abstracts/search?q=triple%20helix" title=" triple helix"> triple helix</a> </p> <a href="https://publications.waset.org/abstracts/69627/enterprise-harmonic-fusion-as-national-sustainability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69627.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">394</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> Optical and Structural Properties of ZnO Quantum Dots Functionalized with 3-Aminopropylsiloxane Prepared by Sol-gel Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Pacio">M.

The growth parameters for ZnO QDs were systematically studied inside a SiO2 shell; this shell acts as a capping agent and also enhances stability of the nanoparticles in water. ZnO QDs in silica shell could be produced by initially synthesizing a ZnO colloid (containing ZnO nanoparticles in methanol solution) and then was mixed with 3-aminopropylsiloxane used as SiO2 precursor. ZnO QDs were deposited onto silicon substrates (100) orientation by spin-coating technique. ZnO QDs into a SiO2 shell were pre-heated at 300 °C for 10 min after each coating, that procedure was repeated five times. The films were subsequently annealing in air atmosphere at 500 °C for 2 h to remove the trapped fluid inside the amorphous silica cage. ZnO QDs showed hexagonal wurtzite structure and about 5 nm in diameter. The composition of the films at the surface and in the bulk was obtained by Secondary Ion Mass Spectrometry (SIMS), the spectra revealed the presence of Zn- and Si- related clusters associated to the chemical species in the solid matrix. Photoluminescence (PL) spectra under 325 nm of excitation only show a strong UV emission band corresponding to ZnO QDs, such emission is enhanced with annealing. Our results showed that the method is appropriate for the preparation of ZnO QDs films embedded in a SiO2 shell with high UV photoluminescence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ZnO%20QDs" title="ZnO QDs">ZnO QDs</a>, <a href="https://publications.waset.org/abstracts/search?q=sol%20gel" title=" sol gel"> sol gel</a>, <a href="https://publications.waset.org/abstracts/search?q=functionalization" title=" functionalization"> functionalization</a> </p> <a href="https://publications.waset.org/abstracts/28662/optical-and-structural-properties-of-zno-quantum-dots-functionalized-with-3-aminopropylsiloxane-prepared-by-sol-gel-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28662.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">433</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> Nanofluid based on Zinc Oxide/Ferric Oxide Nanocomposite as Additive for Geothermal Drilling Fluids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anwaar%20O.%20Ali">Anwaar O.

The reason for carrying out this study lies in the considerable heterogeneity that can be perceived in the data from these countries. We conduct a long memory and fractional integration modeling framework and we also identify potential breaks in the data. The aim of the study is to perceive up to which degree the eight West African countries that belong to the same monetary union follow the same economic patterns of stability. Testing for mean reversion, we only found strong evidence of it in the case of Senegal for the Price level of Consumption, and in the cases of Benin, Burkina Faso and Senegal for GDP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=West%20Africa" title="West Africa">West Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=Monetary%20Union" title=" Monetary Union"> Monetary Union</a>, <a href="https://publications.waset.org/abstracts/search?q=fractional%20integration" title=" fractional integration"> fractional integration</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20patterns" title=" economic patterns"> economic patterns</a> </p> <a href="https://publications.waset.org/abstracts/1887/fractional-integration-in-the-west-african-economic-and-monetary-union" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1887.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">431</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> Learning through Gaming with Mobile Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20Rodrigo%20Valencia%20P%C3%A9rez">Luis Rodrigo Valencia Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Manuel%20Pe%C3%B1a%20Aguilar"> Juan Manuel Peña Aguilar</a>, <a href="https://publications.waset.org/abstracts/search?q=Adelina%20Morita%20Alexander"> Adelina Morita Alexander</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberto%20Lamadrid%20Alvarez"> Alberto Lamadrid Alvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=H%C3%A9ctor%20Fernando%20Valencia%20P%C3%A9rez"> Héctor Fernando Valencia Pérez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Financial education is among the areas of opportunity in the Spanish-speaking from an early age to high school, through mobile devices such as cell phones and tablets using ludic and fun applications like interactive games, children can learn money management and investment through time, thereby fostering the habit of saving and/or sound management of cash and family business resources, having interaction with an uncontrolled environment such as the involvement of other players in the external decisions of the environment in which the game is play.

The results indicate that only the policy of phase-out of lead in gasoline has been effective, showing dropping of lead oxides concentration in the air. Some stakeholders believe that the FFQI evaluated in the study are environmental policies, but no one of these policies has been supported by an environmental impact assessment that shows specific benefits in air quality.

Structural studies carried out by X-ray diffraction method, conﬁrms that the prepared pure ZnO and Pr-doped ZnO nanostructures are in hexagonal wurtzite structure and the microstrain is increased upon doping. TEM analysis reveals that the prepared materials are in the sheet-like nature. Absorption spectra show free excitonic absorption band at 370 nm and red shift for the Pr-doped ZnO nanostructures. The PVA:Zn98Pr2O composite film exhibits both free excitonic and PVA absorption bands at 282 nm.

However, these processes require a significant amount of energy globally. Nowadays, absorption heat pumps have been studied with great interest since they are capable of producing cooling and/or purifying water from low-temperature energy sources such as industrial waste heat or renewable energy. In addition, absorption heat pumps require negligible amounts of electricity for their operation and generally use working fluids that do not represent a risk to the environment. The objective of this work is to evaluate a system that integrates an absorption heat transformer and an absorption cooling system to produce fresh water and cooling from a low-temperature heat source. Both cycles operate with the working pair LiBr-H2O. The integration is possible through the interaction of the LiBr-H2O solution streams between both cycles and also by recycling heat from the absorption heat transformer to the absorption cooling system. Mathematical models were developed to compare the performance of four different configurations. The results showed that the configuration in which the hottest streams of LiBr-H2O solution preheated the coldest streams in the economizers of both cycles was one that achieved the best performance. The interaction of the solution currents and the heat recycling analyzed in this work serves as a record of the possibilities of integration between absorption cycles for cogeneration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorption%20heat%20transformer" title="absorption heat transformer">absorption heat transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=absorption%20cooling%20system" title=" absorption cooling system"> absorption cooling system</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20desalination" title=" water desalination"> water desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20system" title=" integrated system"> integrated system</a> </p> <a href="https://publications.waset.org/abstracts/159517/integration-of-two-thermodynamic-cycles-by-absorption-for-simultaneous-production-of-fresh-water-and-cooling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159517.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">40</span> Classify Land Use/Cover Change and Its Impact on Soil Erosion Using GIS from 2005 to 2015 in Nzhelele Valley Limpopo Province, South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Blessing%20Mavhuru">Blessing Mavhuru</a>, <a href="https://publications.waset.org/abstracts/search?q=Nthaduleni%20Nethengwe"> Nthaduleni Nethengwe</a>, <a href="https://publications.waset.org/abstracts/search?q=Hector%20Chikoore"> Hector Chikoore</a>, <a href="https://publications.waset.org/abstracts/search?q=Onyango%20Beneah%20Daniel%20Odhiambo"> Onyango Beneah Daniel Odhiambo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this study was to classify land use/cover and how it has changed in Nzhelele Valley Limpopo Province, South Africa. The study aimed to identify and analyse the types of land use/cover in the years 2005, 2010, and 2015 with a view to assess the impact on soil erosion over time. Using GIS, the changes within land use/cover were assessed through the classification of satellite images. The study area was classified into four major land cover/use classes, which are vegetation, gravel road, built up land and agricultural fields. Over the period 2005-2015 the resultant land use/cover demonstrated (i) a significant increase (12%) for vegetation cover, (ii) a significant decrease in agriculture (16%) land use/cover, (iii) increase in built-up land (1%), as well as (iv) an increase in gravel roads (3%).

To improve this process, researchers have proposed merely illustrative techniques in the classroom, such as topic presentations and dynamics between students on one side or attempts to involve students in real projects with companies and institutions to bring them to a real software development problem on the other hand. Simulators and serious games have been used as auxiliary tools to introduce students to topics that are too abstract when these are presented in the traditional way. Most of these tools cover a limited area of the huge software engineering scope. To address this problem, we have developed D6tions, an educational serious game that simulates the software engineering process and is designed to experiment the different stages a software engineer (playing roles as project leader or as a developer or designer) goes through, while participating in a software project. We describe previous approaches to this problem, how D6tions was designed, its rules, directions, and the results we obtained of the use of this game involving undergraduate students playing the game. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=serious%20games" title="serious games">serious games</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20engineering" title=" software engineering"> software engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20engineering%20education" title=" software engineering education"> software engineering education</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20engineering%20teaching%20process" title=" software engineering teaching process"> software engineering teaching process</a> </p> <a href="https://publications.waset.org/abstracts/37912/d6tions-a-serious-game-to-learn-software-engineering-process-and-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37912.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">493</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">37</span> The Integration of Patient Health Record Generated from Wearable and Internet of Things Devices into Health Information Exchanges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dalvin%20D.%20Hill">Dalvin D.

The usage and functionality of these wearable devices vary from user to user. One popular usage of said devices is to track health-related activities that are typically stored on a device’s memory or uploaded to an account in the cloud; based on the current trend, the data accumulated from the wearable device are stored in a standalone location. In many of these cases, this health related datum is not a factor when considering the holistic view of a user’s health lifestyle or record. This health-related data generated from wearable and Internet of Things (IoT) devices can serve as empirical information to a medical provider, as the standalone data can add value to the holistic health record of a patient. This paper proposes a solution to incorporate the data gathered from these wearable and IoT devices, with that a patient’s Personal Health Record (PHR) stored within the confines of a Health Information Exchange (HIE). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electronic%20health%20record" title="electronic health record">electronic health record</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20information%20exchanges" title=" health information exchanges"> health information exchanges</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things" title=" internet of things"> internet of things</a>, <a href="https://publications.waset.org/abstracts/search?q=personal%20health%20records" title=" personal health records"> personal health records</a>, <a href="https://publications.waset.org/abstracts/search?q=wearable%20devices" title=" wearable devices"> wearable devices</a>, <a href="https://publications.waset.org/abstracts/search?q=wearables" title=" wearables"> wearables</a> </p> <a href="https://publications.waset.org/abstracts/125668/the-integration-of-patient-health-record-generated-from-wearable-and-internet-of-things-devices-into-health-information-exchanges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125668.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">128</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">36</span> Optimizing Resource Allocation and Indoor Location Using Bluetooth Low Energy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N%C3%A9stor%20%C3%81lvarez-D%C3%ADaz">Néstor Álvarez-Díaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Pino%20Caballero-Gil"> Pino Caballero-Gil</a>, <a href="https://publications.waset.org/abstracts/search?q=H%C3%A9ctor%20Reboso-Morales"> Héctor Reboso-Morales</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Mart%C3%ADn-Fern%C3%A1ndez"> Francisco Martín-Fernández</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The recent tendency of "Internet of Things" (IoT) has developed in the last years, causing the emergence of innovative communication methods among multiple devices. The appearance of Bluetooth Low Energy (BLE) has allowed a push to IoT in relation to smartphones. In this moment, a set of new applications related to several topics like entertainment and advertisement has begun to be developed but not much has been done till now to take advantage of the potential that these technologies can offer on many business areas and in everyday tasks. In the present work, the application of BLE technology and smartphones is proposed on some business areas related to the optimization of resource allocation in huge facilities like airports. An indoor location system has been developed through triangulation methods with the use of BLE beacons. The described system can be used to locate all employees inside the building in such a way that any task can be automatically assigned to a group of employees. It should be noted that this system cannot only be used to link needs with employees according to distances, but it also takes into account other factors like occupation level or category. In addition, it has been endowed with a security system to manage business and personnel sensitive data. The efficiency of communications is another essential characteristic that has been taken into account in this work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bluetooth%20low%20energy" title="bluetooth low energy">bluetooth low energy</a>, <a href="https://publications.waset.org/abstracts/search?q=indoor%20location" title=" indoor location"> indoor location</a>, <a href="https://publications.waset.org/abstracts/search?q=resource%20assignment" title=" resource assignment"> resource assignment</a>, <a href="https://publications.waset.org/abstracts/search?q=smartphones" title=" smartphones"> smartphones</a> </p> <a href="https://publications.waset.org/abstracts/42890/optimizing-resource-allocation-and-indoor-location-using-bluetooth-low-energy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42890.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">394</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">35</span> Flipped Learning Application on the Development of Capabilities for Civil Engineering Education in Labs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hector%20Barrios-Pi%C3%B1a">Hector Barrios-Piña</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgia%20Garc%C3%ADa-Arellano"> Georgia García-Arellano</a>, <a href="https://publications.waset.org/abstracts/search?q=Salvador%20Garc%C3%ADa-Rodr%C3%ADguez"> Salvador García-Rodríguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerardo%20Bocanegra-Garc%C3%ADa"> Gerardo Bocanegra-García</a>, <a href="https://publications.waset.org/abstracts/search?q=Shashi%20Kant"> Shashi Kant</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work shows the methodology of application and the effectiveness of the <em>Flipped Learning</em> technique for Civil Engineering laboratory classes. It was experimented by some of the professors of the Department of Civil Engineering at Tecnológico de Monterrey while teaching their laboratory classes. A total of 28 videos were created. The videos primarily demonstrate instructions of the experimental practices other than the usage of tools and materials. The technique allowed the students to prepare for their classes in advance. A survey was conducted on the participating professors and students (semester of August-December 2019) to quantify the effectiveness of the <em>Flipped Learning</em> technique. The students reported it as an excellent way of improving their learning aptitude, including self-learning whereas, the professors felt it as an efficient technique for optimizing their class session, which also provided an extra slot for class-interaction. A comparison of grades was analyzed between the students of the traditional classes and with <em>Flipped Learning</em>. It did not distinguish the benefits of <em>Flipped Learning</em>. However, the positive responses from the students and the professors provide an impetus for continuing and promoting the <em>Flipped Learning</em> technique in future classes. <p
