containing coil primary for transmission and secondary reception. The topology used in the prototype of the Class-E amplifier, has been identified as optimal for power transfer applications. Characteristic of the inductor and the load are defined by the requirements of the resonant inductive system. The frequency limitation the of circuit restricts unloaded “Q-Factor”, quality factor of the coils and thus the link efﬁciency. With a suitable circuit, copper coil unloaded Q-Factors of over 1,000 can be achieved in the low Mhz region, enabling a cost-effective high Q coil assembly. The circuit is capable system capable of transmitting energy with direct current to load efﬁciency above 60% at 2 Mhz. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20induction" title="magnetic induction">magnetic induction</a>, <a href="https://publications.waset.org/abstracts/search?q=transfer%20of%20electrical%20energy" title=" transfer of electrical energy"> transfer of electrical energy</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20coupling" title=" magnetic coupling"> magnetic coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=Q-Factor" title=" Q-Factor"> Q-Factor</a> </p> <a href="https://publications.waset.org/abstracts/20457/transfer-of-electrical-energy-by-magnetic-induction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20457.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">518</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> Life Prediction of Cutting Tool by the Workpiece Cutting Condition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noemia%20Gomes%20de%20Mattos%20de%20Mesquita">Noemia Gomes de Mattos de Mesquita</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Eduardo%20Ferreira%20de%20Oliveira"> José Eduardo Ferreira de Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Arimatea%20Quaresma%20Ferraz"> Arimatea Quaresma Ferraz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stops to exchange cutting tool, to set up again the tool in a turning operation with CNC or to measure the workpiece dimensions have a direct influence on production. The premature removal of the cutting tool results in high cost of machining since the parcel relating to the cost of the cutting tool increases. On the other hand, the late exchange of cutting tool also increases the cost of production because getting parts out of the preset tolerances may require rework for its use when it does not cause bigger problems such as breaking of cutting tools or the loss of the part. Therefore, the right time to exchange the tool should be well defined when wanted to minimize production costs. When the flank wear is the limiting tool life, the time predetermination that a cutting tool must be used for the machining occurs within the limits of tolerance can be done without difficulty. This paper aims to show how the life of the cutting tool can be calculated taking into account the cutting parameters (cutting speed, feed and depth of cut), workpiece material, power of the machine, the dimensional tolerance of the part, the finishing surface, the geometry of the cutting tool and operating conditions of the machine tool, once known the parameters of Taylor algebraic structure. These parameters were raised for the ABNT 1038 steel machined with cutting tools of hard metal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=machining" title="machining">machining</a>, <a href="https://publications.waset.org/abstracts/search?q=productions" title=" productions"> productions</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20condition" title=" cutting condition"> cutting condition</a>, <a href="https://publications.waset.org/abstracts/search?q=design" title=" design"> design</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing" title=" manufacturing"> manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=measurement" title=" measurement"> measurement</a> </p> <a href="https://publications.waset.org/abstracts/9191/life-prediction-of-cutting-tool-by-the-workpiece-cutting-condition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9191.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">634</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">333</span> Methodology of Preliminary Design and Performance of a Axial-Flow Fan through CFD</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramiro%20Gustavo%20Ramirez%20Camacho">Ramiro Gustavo Ramirez Camacho</a>, <a href="https://publications.waset.org/abstracts/search?q=Waldir%20%20De%20Oliveira"> Waldir De Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Eraldo%20Cruz%20Dos%20Santos"> Eraldo Cruz Dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Edna%20Raimunda%20%20Da%20Silva"> Edna Raimunda Da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Tania%20Marie%20%20Arispe%20Angulo"> Tania Marie Arispe Angulo</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Eduardo%20Alves%20%20Da%20Costa"> Carlos Eduardo Alves Da Costa</a>, <a href="https://publications.waset.org/abstracts/search?q=T%C3%A2nia%20Cristina%20Alves%20%20Dos%20Reis"> Tânia Cristina Alves Dos Reis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It presents a preliminary design methodology of an axial fan based on the lift wing theory and the potential vortex hypothesis. The literature considers a study of acoustic and engineering expertise to model a fan with low noise. Axial fans with inadequate intake geometry, often suffer poor condition of the flow at the entrance, varying from velocity profiles spatially asymmetric to swirl floating with respect to time, this produces random forces acting on the blades. This produces broadband gust noise which in most cases triggers the tonal noise. The analysis of the axial flow fan will be conducted for the solution of the Navier-Stokes equations and models of turbulence in steady and transitory (RANS - URANS) 3-D, in order to find an efficient aerodynamic design, with low noise and suitable for industrial installation. Therefore, the process will require the use of computational optimization methods, aerodynamic design methodologies, and numerical methods as CFD- Computational Fluid Dynamics. The objective is the development of the methodology of the construction axial fan, provide of design the geometry of the blade, and evaluate aerodynamic performance <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Axial%20fan%20design" title="Axial fan design">Axial fan design</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=Preliminary%20Design" title=" Preliminary Design"> Preliminary Design</a>, <a href="https://publications.waset.org/abstracts/search?q=Optimization" title=" Optimization"> Optimization</a> </p> <a href="https://publications.waset.org/abstracts/58823/methodology-of-preliminary-design-and-performance-of-a-axial-flow-fan-through-cfd" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58823.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">396</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> Mathematical Modeling for the Break-Even Point Problem in a Non-homogeneous System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Filipe%20Cardoso%20de%20Oliveira">Filipe Cardoso de Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Lino%20Marcos%20da%20Silva"> Lino Marcos da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Ademar%20Nogueira%20do%20Nascimento"> Ademar Nogueira do Nascimento</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristiano%20Hora%20de%20Oliveira%20Fontes"> Cristiano Hora de Oliveira Fontes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article presents a mathematical formulation for the production Break-Even Point problem in a non-homogeneous system. The optimization problem aims to obtain the composition of the best product mix in a non-homogeneous industrial plant, with the lowest cost until the breakeven point is reached. The problem constraints represent real limitations of a generic non-homogeneous industrial plant for n different products. The proposed model is able to solve the equilibrium point problem simultaneously for all products, unlike the existing approaches that propose a resolution in a sequential way, considering each product in isolation and providing a sub-optimal solution to the problem. The results indicate that the product mix found through the proposed model has economical advantages over the traditional approach used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=branch%20and%20bound" title="branch and bound">branch and bound</a>, <a href="https://publications.waset.org/abstracts/search?q=break-even%20point" title=" break-even point"> break-even point</a>, <a href="https://publications.waset.org/abstracts/search?q=non-homogeneous%20production%20system" title=" non-homogeneous production system"> non-homogeneous production system</a>, <a href="https://publications.waset.org/abstracts/search?q=integer%20linear%20programming" title=" integer linear programming"> integer linear programming</a>, <a href="https://publications.waset.org/abstracts/search?q=management%20accounting" title=" management accounting"> management accounting</a> </p> <a href="https://publications.waset.org/abstracts/143328/mathematical-modeling-for-the-break-even-point-problem-in-a-non-homogeneous-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143328.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">211</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> Using Wiki for Enhancing the Knowledge Transfer to Newcomers: An Experience Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hualter%20Oliveira%20Barbosa">Hualter Oliveira Barbosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Raquel%20Feitosa%20do%20Vale%20Cunha"> Raquel Feitosa do Vale Cunha</a>, <a href="https://publications.waset.org/abstracts/search?q=Erika%20Muniz%20dos%20Santos"> Erika Muniz dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernanda%20Belmira%20Souza"> Fernanda Belmira Souza</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabio%20Sousa"> Fabio Sousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Henrique%20Pascareli"> Luis Henrique Pascareli</a>, <a href="https://publications.waset.org/abstracts/search?q=Franciney%20de%20Oliveira%20Lima"> Franciney de Oliveira Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Cl%C3%A1udia%20Reis%20da%20Silva"> Ana Cláudia Reis da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Christiane%20Moreira%20de%20Almeida"> Christiane Moreira de Almeida</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Software development is intrinsic human-based knowledge-intensive.

Initially dedicated to business management, it currently serves organizations of other natures - such as hospitals. This paper presents a BSC designed for a Portuguese Acute Pain Unit (APU). This study is qualitative and based on the experience of collaborators at the APU. The management of APU is based on four perspectives – users, internal processes, learning and growth, and financial and legal. For each perspective, there were identified strategic objectives, critical factors, lead indicators and initiatives. The strategic map of the APU outlining sustained strategic relations among strategic objectives. This study contributes to the development of research in the health management area as it explores how organizational insufficiencies and inconsistencies in this particular case can be addressed, through the identification of critical factors, to clearly establish core outcomes and initiatives to set up. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20pain%20unit" title="acute pain unit">acute pain unit</a>, <a href="https://publications.waset.org/abstracts/search?q=balanced%20scorecard" title=" balanced scorecard"> balanced scorecard</a>, <a href="https://publications.waset.org/abstracts/search?q=hospital%20management" title=" hospital management"> hospital management</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20performance" title=" organizational performance"> organizational performance</a>, <a href="https://publications.waset.org/abstracts/search?q=Portugal" title=" Portugal"> Portugal</a> </p> <a href="https://publications.waset.org/abstracts/149206/manage-an-acute-pain-unit-based-on-the-balanced-scorecard" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149206.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">148</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> Scientific Production on Lean Supply Chains Published in Journals Indexed by SCOPUS and Web of Science Databases: A Bibliometric Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Botelho%20de%20Sousa">T.

As a strategic model that focuses on reduced cost and waste with fulfilling the needs of customers, LSCM attracts great interest among researchers and practitioners. The purpose of this paper is to present an overview of Lean Supply Chains literature, based on bibliometric analysis through 57 papers published in indexed journals by SCOPUS and/or Web of Science databases. The results indicate that the last three years (2015, 2016, and 2017) were the most productive on LSCM discussion, especially in Supply Chain Management and International Journal of Lean Six Sigma journals. India, USA, and UK are the most productive countries; nevertheless, cross-country studies by collaboration among researchers were detected, by social network analysis, as a research practice, appearing to play a more important role on LSCM studies. Despite existing limitation, such as limited indexed journal database, bibliometric analysis helps to enlighten ongoing efforts on LSCM researches, including most used technical procedures and collaboration network, showing important research gaps, especially, for development countries researchers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lean%20Supply%20Chains" title="Lean Supply Chains">Lean Supply Chains</a>, <a href="https://publications.waset.org/abstracts/search?q=Bibliometric%20Study" title=" Bibliometric Study"> Bibliometric Study</a>, <a href="https://publications.waset.org/abstracts/search?q=SCOPUS" title=" SCOPUS"> SCOPUS</a>, <a href="https://publications.waset.org/abstracts/search?q=Web%20of%20Science" title=" Web of Science"> Web of Science</a> </p> <a href="https://publications.waset.org/abstracts/94811/scientific-production-on-lean-supply-chains-published-in-journals-indexed-by-scopus-and-web-of-science-databases-a-bibliometric-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94811.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">347</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">328</span> A Semantic Registry to Support Brazilian Aeronautical Web Services Operations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lu%C3%ADs%20Antonio%20de%20Almeida%20Rodriguez">Luís Antonio de Almeida Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Maria%20Parente%20de%20Oliveira"> José Maria Parente de Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Ednelson%20Oliveira"> Ednelson Oliveira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the last two decades, the world’s aviation authorities have made several attempts to create consensus about a global and accepted approach for applying semantics to web services registry descriptions. This problem has led communities to face a fat and disorganized infrastructure to describe aeronautical web services. It is usual for developers to implement ad-hoc connections among consumers and providers and manually create non-standardized service compositions, which need some particular approach to compose and semantically discover a desired web service. Current practices are not precise and tend to focus on lightweight specifications of some parts of the OWL-S and embed them into syntactic descriptions (SOAP artifacts and OWL language). It is necessary to have the ability to manage the use of both technologies. This paper presents an implementation of the ontology OWL-S that describes a Brazilian Aeronautical Web Service Registry, which makes it able to publish, advertise, make multi-criteria semantic discovery aligned with the ideas of the System Wide Information Management (SWIM) Program, and invoke web services within the Air Traffic Management context. The proposal’s best finding is a generic approach to describe semantic web services. The paper also presents a set of functional requirements to guide the ontology development and to compare them to the results to validate the implementation of the OWL-S Ontology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aeronautical%20web%20services" title="aeronautical web services">aeronautical web services</a>, <a href="https://publications.waset.org/abstracts/search?q=OWL-S" title=" OWL-S"> OWL-S</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20web%20services%20discovery" title=" semantic web services discovery"> semantic web services discovery</a>, <a href="https://publications.waset.org/abstracts/search?q=ontologies" title=" ontologies"> ontologies</a> </p> <a href="https://publications.waset.org/abstracts/161161/a-semantic-registry-to-support-brazilian-aeronautical-web-services-operations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161161.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">327</span> Attitude towards Doping of High-Performance Athletes in a Sports Institute of the City of Medellin, Colombia </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuban%20Sebastian%20Cuartas-Agudelo">Yuban Sebastian Cuartas-Agudelo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Marcela%20L%C3%B3pez-Hincapi%C3%A9"> Sandra Marcela López-Hincapié</a>, <a href="https://publications.waset.org/abstracts/search?q=Vivianna%20Alexandra%20Garrido-Altamar"> Vivianna Alexandra Garrido-Altamar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20de%20los%20%C3%81ngeles%20Rodr%C3%ADguez-G%C3%A1zquez"> María de los Ángeles Rodríguez-Gázquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Ruiz-Mej%C3%ADa"> Camilo Ruiz-Mejía</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez-S%C3%A1nchez"> Lina María Martínez-Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Gloria%20In%C3%A9s%20Mart%C3%ADnez-Dom%C3%ADnguez"> Gloria Inés Martínez-Domínguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Eduardo%20Contreras"> Luis Eduardo Contreras</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Eduardo%20Marino-Isaza"> Felipe Eduardo Marino-Isaza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Doping is a prohibited practice in competitive sports with potential adverse effects; therefore, it is crucial to describe the attitudes of athletes towards this behavior and to determine which o these increase the susceptibility to carry out this practice. Objective: To determine the attitude of high-performance athletes towards doping in a sports institute in the city of Medellin, Colombia. Methods: We performed a cross-sectional study during 2016, with a sample taken to convenience consisting of athletes over 18 years old enrolled in a sports institute of the city of Medellin (Colombia). The athletes filled by themselves the Petroczi and Aidman questionnaire: Performance Enhancement Attitude Scale (PEAS) adapted to the Spanish language by Morente-Sánchez et al. This scale has 17 items with likert answer options, with a score ranging from 1 to 6, with a higher score indicating a stronger tendency towards doping practices. Results: 112 athletes were included with an average age of 21.6 years old, a 60% of them were male and the most frequent sports were karate 17%, judo 12.5% and athletics 9.8%. The average score of the questionnaire was 35.5 points of a 102 possible points. The lowest score was obtained in the following items: Is Doping necessary 1,4 and Doping isn’t cheating, everyone does it 1,5.

For this reason, the objective of this study was to explore and synthesize results examining the use and effects of music on emotion regulation in children, adults, and elderly, and clarify if the music is effective across ages to promote emotion regulation. A literature search was conducted using ISI Web of Knowledge, Pubmed, PsycINFO, and Scopus, inclusion criteria comprised children, adolescents, young, and old adults, including health population. Articles applying musical intervention, specifically musical listening, and assessing the emotion regulation directly through reports or neurophysiological measures were included in this review. Results showed age differences in the function of musical listening; initially, adolescents revealed age increments in emotional listening compared to children, and young adults in comparison to older adults, in which the first use music aiming to emotion regulation and social connection, while older adults also utilize music as emotion regulation searching for personal growth. Moreover, some of the studies showed that personal characteristics also would determine the efficiency of the emotion regulation strategy. In conclusion, it was observed that music could beneficiate all ages investigated, however, this review detected a necessity to develop adequate paradigms to explore the use of music for emotion regulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=music" title="music">music</a>, <a href="https://publications.waset.org/abstracts/search?q=emotion" title=" emotion"> emotion</a>, <a href="https://publications.waset.org/abstracts/search?q=regulation" title=" regulation"> regulation</a>, <a href="https://publications.waset.org/abstracts/search?q=musical%20listening" title=" musical listening"> musical listening</a> </p> <a href="https://publications.waset.org/abstracts/98460/a-systematic-review-emotion-regulation-through-music-in-children-adults-and-elderly" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98460.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">171</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">325</span> Agile Supply Chains and Its Dependency on Air Transport Mode: A Case Study in Amazon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fabiana%20Lucena%20Oliveira">Fabiana Lucena Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Aristides%20da%20Rocha%20Oliveira%20Junior"> Aristides da Rocha Oliveira Junior</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article discusses the dependence on air transport mode of agile supply chains. The agile supply chains are the result of the analysis of the uncertainty supply chain model, which ranks the supply chain, according to the respective product. Thus, understanding the Uncertainty Model and life cycle of products considered standard and innovative is critical to understanding these. The innovative character in the intersection of supply chains arising from the uncertainty model with its most appropriate transport mode. Consider here the variables availability, security and freight as determinants for choosing these modes. Therefore, the research problem is: How agile supply chains maintains logistics competitiveness, as these are dependent on air transport mode? A case study in Manaus Industrial Pole (MIP), an agglomeration model that includes six hundred industries from different backgrounds and billings, located in the Brazilian Amazon. The sample of companies surveyed include those companies whose products are classified in agile supply chains , as innovative and therefore live with the variable uncertainty in the demand for inputs or the supply of finished products. The results confirm the hypothesis that the dependency level of air transport mode is greater than fifty percent. It follows then, that maintain agile supply chain away from suppliers base is expensive (1) , and continuity analysis needs to be remade on each twenty four months (2) , consider that additional freight, handling and storage as members of the logistics costs (3) , and the comparison with the upcoming agile supply chains the world need to consider the location effect (4). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=uncertainty%20model" title="uncertainty model">uncertainty model</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20transport%20mode" title=" air transport mode"> air transport mode</a>, <a href="https://publications.waset.org/abstracts/search?q=competitiveness" title=" competitiveness"> competitiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=logistics" title=" logistics "> logistics </a> </p> <a href="https://publications.waset.org/abstracts/26173/agile-supply-chains-and-its-dependency-on-air-transport-mode-a-case-study-in-amazon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26173.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">511</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">324</span> Wear Performance of SLM Fabricated 1.2709 Steel Nanocomposite Reinforced by TiC-WC for Mould and Tooling Applications </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Ferreira">Daniel Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20M.%20Marques%20Oliveira"> José M.

When very abrasive materials are being injected inside the steel mould’s cavities, such as polymers reinforced with abrasive fibres, the consequences of the wear are more evident. Maraging steel (1.2709) is commonly employed in moulding components to resist in very aggressive injection conditions. In this work, the wear performance of the SLM produced 1.2709 maraging steel reinforced by ultrafine titanium and tungsten carbide (TiC-WC), was investigated using a pin-on-disk testing apparatus. A polypropylene reinforced with 40 wt.% fibreglass (PP40) disk, was used as the counterpart material. The wear tests were performed at 40 N constant load and 0.4 ms-1 sliding speed at room temperature and humidity conditions. The experimental results demonstrated that the wear rate in the 18Ni300-TiC-WC composite is lower than the unreinforced 18Ni300 matrix. The morphology and chemical composition of the worn surfaces was observed by 3D optical profilometry and scanning electron microscopy (SEM), respectively. The resulting debris, caused by friction, were also analysed by SEM and energy dispersive X-ray spectroscopy (EDS). Their morphology showed distinct shapes and sizes, which indicated that the wear mechanisms, may be different in maraging steel produced by casting and SLM. The coefficient of friction (COF) was recorded during the tests, which helped to elucidate the wear mechanisms involved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=selective%20laser%20melting" title="selective laser melting">selective laser melting</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposites" title=" nanocomposites"> nanocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=injection%20moulding" title=" injection moulding"> injection moulding</a>, <a href="https://publications.waset.org/abstracts/search?q=polypropylene%20with%20fibreglass" title=" polypropylene with fibreglass"> polypropylene with fibreglass</a> </p> <a href="https://publications.waset.org/abstracts/136638/wear-performance-of-slm-fabricated-12709-steel-nanocomposite-reinforced-by-tic-wc-for-mould-and-tooling-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136638.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">155</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">323</span> Electrochemical Behavior of Cocaine on Carbon Paste Electrode Chemically Modified with Cu(II) Trans 3-MeO Salcn Complex</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alex%20Soares%20Castro">Alex Soares Castro</a>, <a href="https://publications.waset.org/abstracts/search?q=Matheus%20Manoel%20Teles%20de%20Menezes"> Matheus Manoel Teles de Menezes</a>, <a href="https://publications.waset.org/abstracts/search?q=Larissa%20Silva%20de%20Azevedo"> Larissa Silva de Azevedo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Carolina%20Caleffi%20Patelli"> Ana Carolina Caleffi Patelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Osmair%20Vital%20de%20Oliveira"> Osmair Vital de Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Aline%20Thais%20Bruni"> Aline Thais Bruni</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Firmino%20de%20Oliveira"> Marcelo Firmino de Oliveira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Considering the problem of the seizure of illicit drugs, as well as the development of electrochemical sensors using chemically modified electrodes, this work shows the study of the electrochemical activity of cocaine in carbon paste electrode chemically modified with Cu (II) trans 3-MeO salcn complex. In this context, cyclic voltammetry was performed on 0.1 mol.L⁻¹ KCl supporting electrolyte at a scan speed of 100 mV s⁻¹, using an electrochemical cell composed of three electrodes: Ag /AgCl electrode (filled KCl 3 mol.L⁻¹) from Metrohm® (reference electrode); a platinum spiral electrode, as an auxiliary electrode, and a carbon paste electrode chemically modified with Cu (II) trans 3-MeO complex (as working electrode). Two forms of cocaine were analyzed: cocaine hydrochloride (pH 3) and cocaine free base form (pH 8). The PM7 computational method predicted that the hydrochloride form is more stable than the free base form of cocaine, so with cyclic voltammetry, we found electrochemical signal only for cocaine in the form of hydrochloride, with an anodic peak at 1.10 V, with a linearity range between 2 and 20 μmol L⁻¹ had LD and LQ of 2.39 and 7.26x10-5 mol L⁻¹, respectively. The study also proved that cocaine is adsorbed on the surface of the working electrode, where through an irreversible process, where only anode peaks are observed, we have the oxidation of cocaine, which occurs in the hydrophilic region due to the loss of two electrons. The mechanism of this reaction was confirmed by the ab-inito quantum method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ab-initio%20computational%20method" title="ab-initio computational method">ab-initio computational method</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20method" title=" analytical method"> analytical method</a>, <a href="https://publications.waset.org/abstracts/search?q=cocaine" title=" cocaine"> cocaine</a>, <a href="https://publications.waset.org/abstracts/search?q=Schiff%20base%20complex" title=" Schiff base complex"> Schiff base complex</a>, <a href="https://publications.waset.org/abstracts/search?q=voltammetry" title=" voltammetry"> voltammetry</a> </p> <a href="https://publications.waset.org/abstracts/93544/electrochemical-behavior-of-cocaine-on-carbon-paste-electrode-chemically-modified-with-cuii-trans-3-meo-salcn-complex" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93544.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">194</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">322</span> Central Finite Volume Methods Applied in Relativistic Magnetohydrodynamics: Applications in Disks and Jets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raphael%20de%20Oliveira%20Garcia">Raphael de Oliveira Garcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Rocha%20de%20Oliveira"> Samuel Rocha de Oliveira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We have developed a new computer program in Fortran 90, in order to obtain numerical solutions of a system of Relativistic Magnetohydrodynamics partial differential equations with predetermined gravitation (GRMHD), capable of simulating the formation of relativistic jets from the accretion disk of matter up to his ejection. Initially we carried out a study on numerical methods of unidimensional Finite Volume, namely Lax-Friedrichs, Lax-Wendroff, Nessyahu-Tadmor method and Godunov methods dependent on Riemann problems, applied to equations Euler in order to verify their main features and make comparisons among those methods. It was then implemented the method of Finite Volume Centered of Nessyahu-Tadmor, a numerical schemes that has a formulation free and without dimensional separation of Riemann problem solvers, even in two or more spatial dimensions, at this point, already applied in equations GRMHD. Finally, the Nessyahu-Tadmor method was possible to obtain stable numerical solutions - without spurious oscillations or excessive dissipation - from the magnetized accretion disk process in rotation with respect to a central black hole (BH) Schwarzschild and immersed in a magnetosphere, for the ejection of matter in the form of jet over a distance of fourteen times the radius of the BH, a record in terms of astrophysical simulation of this kind. Also in our simulations, we managed to get substructures jets. A great advantage obtained was that, with the our code, we got simulate GRMHD equations in a simple personal computer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20volume%20methods" title="finite volume methods">finite volume methods</a>, <a href="https://publications.waset.org/abstracts/search?q=central%20schemes" title=" central schemes"> central schemes</a>, <a href="https://publications.waset.org/abstracts/search?q=fortran%2090" title=" fortran 90"> fortran 90</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic%20astrophysics" title=" relativistic astrophysics"> relativistic astrophysics</a>, <a href="https://publications.waset.org/abstracts/search?q=jet" title=" jet"> jet</a> </p> <a href="https://publications.waset.org/abstracts/19952/central-finite-volume-methods-applied-in-relativistic-magnetohydrodynamics-applications-in-disks-and-jets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19952.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">454</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">321</span> Ozone Therapy and Pulsed Electromagnetic Fields Interplay in Controlling Tumor Growth, Symptom and Pain Management: A Case Report </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20F.%20Pollo%20Gaspary">J.

Two techniques, ozone therapy and pulsed electromagnetic fields (PEMF), are independently associated with an increase in the immune system functions and they maybe help palliative care of patients in these conditions. Case Report: A patient with rectal adenocarcinoma with metastases decides to interrupt the clinical chemotherapy protocol due to refractoriness and side effects. As a palliative care alternative treatment it is suggested to the patient the use of ozone therapy associated with PEMF techniques. Results: The patient reports an improvement in well-being, in autonomy and in pain control. Imaging tests confirm a pause in tumor growth despite more than 60 days without using classic treatment. These results associated with palliative care alternative treatment stimulate the return to the chemotherapy protocol. Discussion: This case illustrates that these two techniques can contribute to the control of tumor growth and refractory symptoms, such as pain, probably by enhancing the immune system. Conclusions: The potential use of the combination of these two therapies, ozone therapy and PEMF therapy, can contribute to palliation of cancer patients, alone or in combination with pharmacological therapies. The conduct of future investigations on this paradigm can elucidate how much these techniques contribute to the survival and well-being of these patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer" title="cancer">cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=complementary%20and%20alternative%20medicine" title=" complementary and alternative medicine "> complementary and alternative medicine </a>, <a href="https://publications.waset.org/abstracts/search?q=ozone%20therapy" title=" ozone therapy"> ozone therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=palliative%20care" title=" palliative care"> palliative care</a>, <a href="https://publications.waset.org/abstracts/search?q=PEMF%20therapy" title=" PEMF therapy"> PEMF therapy</a> </p> <a href="https://publications.waset.org/abstracts/129242/ozone-therapy-and-pulsed-electromagnetic-fields-interplay-in-controlling-tumor-growth-symptom-and-pain-management-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129242.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">155</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> Touching Interaction: An NFC-RFID Combination</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20%C3%81lvarez">Eduardo Álvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerardo%20Quiroga"> Gerardo Quiroga</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Orozco"> Jorge Orozco</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriel%20Chavira"> Gabriel Chavira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> AmI proposes a new way of thinking about computers, which follows the ideas of the Ubiquitous Computing vision of Mark Weiser. In these, there is what is known as a Disappearing Computer Initiative, with users immersed in intelligent environments. Hence, technologies need to be adapted so that they are capable of replacing the traditional inputs to the system by embedding these in every-day artifacts. In this work, we present an approach, which uses Radiofrequency Identification (RFID) and Near Field Communication (NFC) technologies. In the latter, a new form of interaction appears by contact. We compare both technologies by analyzing their requirements and advantages. In addition, we propose using a combination of RFID and NFC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=touching%20interaction" title="touching interaction">touching interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=ambient%20intelligence" title=" ambient intelligence"> ambient intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=ubiquitous%20computing" title=" ubiquitous computing"> ubiquitous computing</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction" title=" interaction"> interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=NFC%20and%20RFID" title=" NFC and RFID"> NFC and RFID</a> </p> <a href="https://publications.waset.org/abstracts/40339/touching-interaction-an-nfc-rfid-combination" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40339.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">505</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">319</span> An Experience Report on Course Teaching in Information Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Oliveira">Carlos Oliveira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is a criticism of the traditional model of teaching and presents alternative teaching methods, different from the traditional lecture. These methods are accompanied by reports of experience of their application in a class. It was concluded that in the lecture, the student has a low learning rate and that other methods should be used to make the most engaging learning environment for the student, contributing (or facilitating) his learning process. However, the teacher should not use a single method, but rather a range of different methods to ensure the learning experience does not become repetitive and fatiguing for the student. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=educational%20practices" title="educational practices">educational practices</a>, <a href="https://publications.waset.org/abstracts/search?q=experience%20report" title=" experience report"> experience report</a>, <a href="https://publications.waset.org/abstracts/search?q=IT%20in%20education" title=" IT in education"> IT in education</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20methods" title=" teaching methods"> teaching methods</a> </p> <a href="https://publications.waset.org/abstracts/55692/an-experience-report-on-course-teaching-in-information-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55692.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">397</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">318</span> Instructional Design Strategy Based on Stories with Interactive Resources for Learning English in Preschool</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vicario%20Marina">Vicario Marina</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruiz%20Elena"> Ruiz Elena</a>, <a href="https://publications.waset.org/abstracts/search?q=Peredo%20Ruben"> Peredo Ruben</a>, <a href="https://publications.waset.org/abstracts/search?q=Bustos%20Eduardo"> Bustos Eduardo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> the development group of Educational Computing of the National Polytechnic (IPN) in Mexico has been developing interactive resources at preschool level in an effort to improve learning in the Child Development Centers (CENDI).

Due to its specificities, this vocational program starts at a very young age. Although provided by the State, the offer is limited to 6 schools throughout the country, which means that the vacancies for prospective students are very limited every year. It is therefore crucial that these vacancies be taken by especially motivated children grown within households that offer the ideal setting for success. Some of the instruments used to evaluate musical performance are highly sensitive to specific previous training, what represents a severe validity problem for testing children who have had restricted opportunities for formal training. Moreover, these practices may be unfair because, for instance, they may not reflect the candidates’ music aptitudes. Based on what constitutes a prerequisite for making an excellent music student, researchers in this field have long argued that motivation, task commitment, and parents’ support are as important as ability. Thus, the aim of this study is: (1) to prepare an inventory of admission requirements in Australia, Portugal and Ireland; (2) to examine whether the candidates to music conservatories and parents’ level of motivation, assessed at three evaluation points (i.e., admission, at the end of the first year, and at the end of the second year), correlates positively with the candidates’ progress in learning a musical instrument (i.e., whether motivation at the admission may predict student musicianship); (3) an adaptation of an existing instrument to assess the motivation (i.e., to adapt the items to the music setting, focusing on the motivation for playing a musical instrument). The inclusion criteria are: only children registered in the administrative services to be evaluated for entrance to the conservatory will be accepted for this study. The expected number of participants is fifty (5-6 years old) in all the three frequency schemes: integrated, articulated and supplementary. Revisiting musical admission procedures is of particular importance and relevance to musical education because this debate may bring guidance and assistance about the needed improvement to make the process of admission fairer and more transparent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=music%20learning" title="music learning">music learning</a>, <a href="https://publications.waset.org/abstracts/search?q=music%20admission%20requirements" title=" music admission requirements"> music admission requirements</a>, <a href="https://publications.waset.org/abstracts/search?q=student%E2%80%99s%20motivation" title=" student’s motivation"> student’s motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=parent%E2%80%99s%20motivation" title=" parent’s motivation"> parent’s motivation</a> </p> <a href="https://publications.waset.org/abstracts/98453/characterization-of-the-music-admission-requirements-and-evaluation-of-the-relationship-among-motivation-and-performance-achievement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98453.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">166</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">316</span> Spectral Analysis Applied to Variables of Oil Wells Profiling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suzana%20Leit%C3%A3o%20Russo">Suzana Leitão Russo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayara%20Laysa%20de%20Oliveira%20Silva"> Mayara Laysa de Oliveira Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Augusto%20Andrade%20Filho"> José Augusto Andrade Filho</a>, <a href="https://publications.waset.org/abstracts/search?q=Vitor%20Hugo%20Simon"> Vitor Hugo Simon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently, seismic methods and prospecting methods are commonly applied in the oil industry and, according to the information reported every day; oil is a source of non-renewable energy.

To do so, the study was based on a theoretical framework that covers the modernization of public administration to performance management, passing on people management. The work consisted of qualitative-descriptive research in which 16 semi-structured interviews were applied in the countries of study and documents and legislation were used referring to the subject. Performance management, as well as other people management subsystems, is criticized for using private sector management tools, based on a results-driven logic. From this point of view, it is understood that certain practices of the private sector, regarding the measurement of performance, can not be simply inserted in the scenario of the public administration. Beyond this criticism, performance management can contribute to the achievement of the strategic objectives of the countries and its focus is upward, a trend that can be verified through the manuals produced; by the interest of consultants and professional organizations, both public and private; and OECD (Organization for Economic Cooperation and Development) evaluations. In Portugal, public administration reform was implemented during the Constitutional Government (2005-2009) and had as its objective the restructuring of human resources management, with an emphasis on its integration with budget management, which is an inclination of the OECD, while in Chile HRM (Human Resource Management) practices are directed to ministries to a lesser extent than the OECD average. The central human resources management sector, for the most part, coordinates policy but is also responsible for other issues, including payment and classification systems. Chile makes less use of strategic Human Resource Management practices than the average of OECD countries, and its prominence lies in the decentralization of public bodies, which may grant autonomy, but fragments the implementation of policies and practices in that country since they are not adopted by all organs. Through the analysis, it was possible to identify that Chile and Portugal have practices and personnel management policies that make reference to performance management, which is similar to other OECD countries. The study countries also have limitations to implement performance management and the results indicate that there are still processes to be perfected, such as performance appraisal and compensation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=management%20of%20people%20in%20the%20public%20sector" title="management of people in the public sector">management of people in the public sector</a>, <a href="https://publications.waset.org/abstracts/search?q=modernization%20of%20public%20administration" title=" modernization of public administration"> modernization of public administration</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20management%20in%20the%20public%20sector" title=" performance management in the public sector"> performance management in the public sector</a>, <a href="https://publications.waset.org/abstracts/search?q=HRM" title=" HRM"> HRM</a>, <a href="https://publications.waset.org/abstracts/search?q=OECD" title=" OECD"> OECD</a> </p> <a href="https://publications.waset.org/abstracts/123748/performance-management-in-public-administration-on-chile-and-portugal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123748.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">152</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">310</span> An Experimental Study of Diffuser-Enhanced Propeller Hydrokinetic Turbines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matheus%20Nunes">Matheus Nunes</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafael%20Mendes"> Rafael Mendes</a>, <a href="https://publications.waset.org/abstracts/search?q=Taygoara%20Felamingo%20Oliveira"> Taygoara Felamingo Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Brasil%20Junior"> Antonio Brasil Junior</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wind tunnel experiments of horizontal axis propeller hydrokinetic turbines model were carried out, in order to determine the performance behavior for different configurations and operational range.

Two forms of applications of the ultrasound were evaluated aiming to increase reaction rates, wherein the use of probe ultrasound associated with the use of surfactant to pre-emulsify the substrate showed the best results. Two different reaction periods were found: the first where the ultrasound has great influence on reaction rates, and the second where ultrasound influence is minimal. Studies on the time of pre-emulsification, surfactant concentration and enzyme concentration showed that the initial rate of hydrolysis depends on the interfacial area between the oil phase and the aqueous phase containing the enzyme. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=specific%20enzyme" title="specific enzyme">specific enzyme</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20fatty%20acids" title=" free fatty acids"> free fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=Hydrolysis" title=" Hydrolysis"> Hydrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=lecitase%20ultra" title=" lecitase ultra"> lecitase ultra</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a> </p> <a href="https://publications.waset.org/abstracts/20337/effect-of-ultrasound-on-the-hydrolysis-of-soy-oil-catalyzed-by-13-specific-lipase-abstract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20337.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">578</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">308</span> Design and Study of a DC/DC Converter for High Power, 14.4 V and 300 A for Automotive Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J%C3%BAlio%20Cesar%20Lopes%20de%20Oliveira">Júlio Cesar Lopes de Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Henrique%20Gon%C3%A7alves%20Treviso"> Carlos Henrique Gonçalves Treviso</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The shortage of the automotive market in relation to options for sources of high power car audio systems, led to development of this work.

One of main objectives is the reduction to a minimum of the user’s interactive effort, the diversity and quantity of devices with which people are surrounded with, in existing environments; increase the level of difficulty to achieve this goal. The mobile phones and their amazing global penetration, makes it an excellent device for delivering new services to the user, without requiring a learning effort. The environment will have to be able to perceive all of the interaction techniques.
