Full textThe interest in permanent-magnets or pure reluctance synchronous machines has increased rapidly in the last years. This trend is a combination of factors: the technological progress and a closer attention to environmental issues to reduce greenhouse gas emissions and to support a green economy. The diffusion of electrical machines in the industrial industry, transports and household appliances could be split in two types: • Electrification, that means chancing the technologies relying on non-renewable sources with hybrid or full electric systems; • The transition from electrical machines based on traditional technologies, but less efficient, to more efficient electrical machines. The automotive is major industry of the electrification process followed to the other transportation industries e.g. railways, aircraft, etc. The 50% of global electric energy is converted in electric motor of which the 80% relies on traditional technologies. These motors are reliable, but less efficient. As a consequence, many companies are adopting more efficient motors or more convenient ones from a control point of view under the pressure of International Standards and European Directives. The contribution of this thesis is developing design methods of synchronous electrical machines with the aim to improve their performance, reliability and fault-tolerant capability. For that purpose, the research activity has focused on some fundamental issues. The first topic is the study of optimization machine design methods inclusive of typical manufacturing defects even in healthy machine conditions. The aim is analyzing the defect influence on performance and improving machine reliability and robustness. After this study, it is followed a research on the demagnetization issue of surface permanent-magnet machines with a special consideration of magnets eddy currents. The activity result is a new design of internal permanent-magnet rotor which has prototyped and tested. The last topic is a study of fault-tolerant capability of a pure reluctance synchronous machine with two independent three-phase windings fed by two inverters. The machine geometry has optimized according to both optimal and fault conditions; the design with the best performance in fault conditions has been chosen and it has been analyzed with respect to different parameters in healthy condition and with one faulty winding.

But now, little available information exists about the production and application of this concrete with lightweight aggregate, additions and addictive national. The aim of this dissertation is to analyze the structural behavior, by mechanical tests (compressive strength, splitting tensile strength and deformation modulus) of HPLC, under action of high temperatures. For so much, it takes place a comparative analysis of the mechanical resistance of the concrete in study, constituted by lightweight aggregate of expanded clay, with the conventional concrete HPC (high performance concrete), composed by crushed basalt coarse aggregate, determining the respective mechanical strength, after they have been exposed to external temperatures of up to 800°C. Through the analysis of the results obtained experimentally, it can be proven the viability of HPLC, produced with expanded clay, comparatively to HPC, under to the action of high temperatures.

Ingolf Dahl’s Concerto for Alto Saxophone and Wind Orchestra is considered a master concert work in saxophone literature. The work was written for saxophone pioneer Sigurd Rascher who was active in commissioning new works for the instrument. Piet Swerts’ Klonos, composed over 40 years after Dahl’s Concerto, is a much newer composition. The work has gained national recognition as a popular competition piece and is a synthesis of new and old compositional styles. These two works strongly showcase the flexibility and virtuosity capable of the skilled saxophonist. This master’s report, presented as extended program notes, includes biographical information about the composers, a historical and stylistic overview of the selected compositions, and a harmonic and formal analysis of the music with respect to performance considerations.

Full textThis work presents a study of the best known ATM traffic policing mechanism and an analysis of management conditions using the SNMP (Simple Network Management Protocol). For this reason the managed objects were considerated pertaining to MIBs (Management Information Base) proposed by many working groups. This work inquires the possibility of managing the traffic policing process using the objects of this selected MIBs. Realizing this management, it can follow the network state and to utilize these informations in the planning of network capacity, because many times, the congestion only not happen for traffic excess but it occurs by worse dimension of the computer networks components. It was studied many traffic and congestion control mechanisms. These mechanisms belong to two procedures proposed by the ATM Forum: usage/network parameter control and feedback control mechanism. The algorithms studied for the usage/network parameter control were: leaky bucket, virtual leaky bucket, buffered leaky bucket, jumping window, moving window, peak counters and generic cell rate algorithm. The feedback control has two variations: credit-based and rate-based. The second mechanism was better accepted internationally, and many algorithms followed its principles. The algorithms were: rate based flow control, explicit rate control, VS/VD (Virtual Source / Virtual Destination), PRCA (Proportional Rate Control Algorithm), EPRCA (Enhanced Proporcional Rate Control Algorithm), ERICA (Explicit Rate Indication for Congestion Avoidance) e CAPC (Congestion Avoidance using Proportional Control). This work studies the two basic mechanism and the rate-based algorithms. The inspected MIBs for this work were: RFC I695's MIB [AHM 94], definitions of supplemental managed objects for ATM management [LY 96], ATM Forum ATM UNI 3.1 Specification's MIB [CHA 96], ATM Forum M4 interface's MIB [ATM 96] , Bay Networks enterprise's MIB [BAY 96] and Cisco enterprise's MIB [WAN 96] [CHA 96a], [GRO 96], [GRO 96a], [RBH 96] e [BAK 96]. As a result of the study of the traffic and congestion control mechanisms and the analysis of selected MIBs, table were built that try to relate the necessary parameters to control traffic and congestion mechanisms with the managed objects. Each control parameter is examined if it has a managed object or a object arrangement that can supply the parameter value. This analysis will verify if managed objects can control traffic and congestion control.

Full textThe yerba mate Market has been growing and getting featured in the most important countries and states which produces it, using the yerba mate not only for it’s traditional drink, “the chimarrão”, but with other alternative uses that has been appearing because of it’s important properties. Due to the increasing of the demand in different kinds of markets, they request the need of researches which evaluate and confirms the conditioning facts of the performance aiming to generate informations to subsidize priority actions of the improvement for it’s increasing sector. In this case, the actual research had as objective to identify the factors which condition the “ervateiras” industries performance from Alto Taquari/RS. As the theoretical contribution for the subsidized review of the data had used the Economical Industry theory, the Costs Economy of transactions and the theory which had involved the use of Importance-Performance Matrix. The primary data were collected through structured questionnaires in a quantitative way, using the likert scale of 1-7 points. The questionnaires were applied via Google Docs and after that shown physically through the industry agents in the “ervateiro” pole from Alto Taquari/RS. The questionnaire was structured in seven sections, both first and second questions referred to the gathered information about the interviewed people and the “ervateiras” industries, which had as objective describe and characterize the studied objetct. The four other sections referred to the conditioning dimensions of the performance, which are they: Production Factors/ Markets/ Logistics/ Institutional Ambient/ and the seventh section was about the view of the productive chain of yerba mate seen by the “ervateiras” industries. The analytical method of the data was consisted in the application of the matrix importance-performance suggested by Slack, Chambers and Johnston (2002), in which provide information about the importance level and assigned performance of the factors that made each one of these dimensions. The data was organized in spreadsheets of the excel and submitted to a describing statistic analysis, with average values referred to the degree of importance and the average referred to the level of performance for each dimension analyzed. With the result of research it is concluded that the dimension of “production factors” the necessary items of the improvement actions are the availability of the raw material , the acquisition cost of the machinery, the availability of labor and the possession and capacity of the machinery. In the “market” dimension, the items that have the need of 11 improvement actions are the factors about the swapped products, the placement of the product in outside market, the degree of concentrations of the raw material developers and the final product’s quality. In the logistic dimension some factors were placed in the urgent-action-zone, like the cost of means of transportation to the industry, the storage capacity to the industry, conditions of the transport to de industry and the conditions of the storage to the industry. In the same dimension, some factors like the flow of technological information, the contract between the industry and the producer, the contract between and the retail, the costs of the storage for the industries needs the improvement actions. In the “Institutional Ambient” dimension, the factors which refers to the macroeconomic indicators, environmental legislation and the agroindustrial process, the environmental legislation and the rural production, sanitary inspection and the agroindustrial process and the access to the credit condition for the industries still need the actions of improvement to increase it’s performance. This condition should provide subsidies and information that will contribute with the decision taken and in the establishment of business strategies with the desire of increasing the performance of the activities inside the “ervateiras” industries, turning into the most competitive one in the market which they are part of.

Full textThe research project was developed in the strict sensu post-graduate course, master's degree in Education at the Catholic University of Campinas. It is framed in the field of Social Sciences, specifically in the area of Education, in the line of research: Public Policy in Education. It aimed to study the good school practices and high performance factors in schools located in high social vulnerability regions. In order to achieve the proposed objectives a review of the literature was carried out, establishing the so-called the State of the Question. Then there was a field survey to collect empirical data through semi-structured interviews and focus groups with principals, teachers, staff, students and parents in two schools in the municipal schools in Ferraz de Vasconcelos, selected according to the results of the Basic Education Development Index 2011 and based in S?o Paulo Social Vulnerability Index, of the State System of Data Analysis Foundation. Among these schools, one had high performance in 2011, and the other one, low performance. Both school units are located in highly vulnerable regions. In terms of methodology we adopted Durkheimian and Weberian principles, classics of Sociology of Education, to support the theoretical foundations of the research. We identified fourteen good school practices and fifteen high performance factors in the school of high social vulnerability. It was evident that good practice and school factors related to pedagogical practices were what most influenced the outcomes of high social vulnerability school, followed by school resources, management and school climate

Full textThe aim of the present work was to develop new improved magnetic materials suitable for permanent magnets. Two kinds of materials were studied: (Nd,Sm)5(Fe,MT)17 based materials, were MT is a transition metal and, (Nd,Pr)FeB nanocrystalline materials (exchange spring magnets) with TiC additions. The 5:17 alloys were melted in an arc melting furnace followed by a long annealing (at least 30 days). We tried to improve the magnetic properties by means of chemical substitutions (Ti, Co, Mn, etc.) and/or by addition of interstitial atoms of deuterium or nitrogen. The samples were characterized by means of thermomagnetic analysis (TMA), low temperature magnetometry, X ray and neutron diffraction, and Mössbauer spectroscopy. The main results were: a) increase of Tc temperature (up to 70 ºC) and; b) determination of interstitial sites for deuterium. (Nd,Pr)FeB alloys with TiC additions were melted in an arc melting furnace, being processed in a melt spinner system. After the samples were heat treated at different temperatures. The promissing literature results for Nd2Fe14B+TiC were also obtained for Pr2Fe14B + TiC, but not for systems composed by Pr2Fe14B and Fe3B phases with TiC additions. However, good results were obtained in systems composed by Pr2Fe14B and α-Fe with TiC additions, with 30% increase on coercive field values Hc, and 15% increase on (BH)max.

The development of quantum algorithms is not a easy task. Elements such as entanglement and quantum paralelism, intrinsics to quantum computation, difficult this task. Quantum walks are crucial tools for development of algorithms, mainly search algorithms. There are many types of quantum walks: with coin toss, Szegedy's, using tessellation (grouping of vertices) and the continuous-time quantum walk. To extract statistics data of a quantum walk, we need to perform its simulation. In this work, we develped the simulator Hiperwalk, a new simulator of quantum walks in graphs of one and two dimension for the quantum walk with a coin toss and coinless using tessellation. The Hiperwalk allows the user to perform simulations of quantum walks in graphs using high performance computing (HPC), even though the user does not knowing parallel programming. The user can employ the parallel devices such as CPU, GPGPU and accelerators cards to speedup the overall process of the walk.
O desenvolvimento de algoritmos quânticos não é uma tarefa trivial. Elementos como emaranhamento e paralelismo quântico, intrínsecos à computação quântica, dificultam esta tarefa. As caminhadas quânticas são ferramentas cruciais para o desenvolvimento de algoritmos, principalmente algoritmos de busca. Existem na literatura vários tipos de caminhadas: com lançamento de moeda, de Szegedy, utilizando tesselagem (agrupamento de vértices) e a caminhada a tempo contínuo. Para extrair dados estatísticos de uma determinada caminhada quântica, necessitamos fazer sua simulação. Neste trabalho, desenvolvemos o simulador Hiperwalk, um novo simulador de caminhadas quânticas, em grafos de uma e duas dimensões para as caminhadas com moeda e sem moeda utilizando tesselagem. O Hiperwalk permite ao usuário efetuar simulações de caminhadas quânticas em grafos utilizando processamento de alto desempenho, mesmo que o usuário não saiba programação paralela. O usuário pode empregar os dispositivos de paralelismo como CPU, GPGPU e co-processadores para acelerar o processo geral da caminhada.

Full textPortugal has strong musical traditions, which have been perpetrated by decades through folkloristic activities. In folk groups from Alto Minho (north of Portugal), folk singing is mostly performed by cantadeiras, amateur female solo singers who learn this style orally. Their vocal characteristics are distinctive when compared with other regions of the country; however, deep understanding of these vocal practices is still missing. The present work aims at studying Alto Minho cantadeira’s vocal performance in a multidimensional perspective, envisioning social, cultural and physiological understanding of this musical style. Thus, qualitative and quantitative data analyses were carried out, to: (i) describe current performance practices, (ii) explore existent perceptions about most relevant voice features in this region, (iii) investigate physiological and acoustic properties of this style, and (iv) compare this style of singing with other non-classical singing styles of other countries. Dataset gathered involved: 78 groups whose members were telephone interviewed, 13 directors who were asked to fill in a questionnaire on performance practices, 1 cantadeira in a pilot study, 16 cantadeiras in preliminary voice recordings, 77 folk group members in listening tests, and 10 cantadeiras in multichannel recordings, including audio, ELG, air flow and intra-oral pressure signals. Data were analysed through thematic content analysis, descriptive and inferential statistics, hierarchical principal components, and multivariate linear regression models. Most representative voices have a high pitched and loud voice, with a bright timbre, predominance of chest register without excessive effort, and good text intelligibility with regional accent. High representativeness levels were obtained by few cantadeiras; these sing with high levels of subglottal pressure and vocal fold contact quotient, predominance of high spectrum energy and vocal loudness, corroborating indications of prevalence of pressed phonation. These vocal characteristics resemble belting in musical theatre and share similarities with country (USA) and ojikanje (Croatia) singing. Strategies that may contribute to the preservation of this type of singing and the vocal health of current cantadeiras are discussed, pointing at the direction of continuous education among folk groups, following practices that are already adopted elsewhere in Europe.
Portugal é um país com fortes tradições musicais perpetuadas ao longo de décadas através das práticas folclóricas. Nos grupos folclóricos da região do Alto Minho, o canto é maioritariamente praticado por cantadeiras, cantoras amadoras cuja aprendizagem é feita maioritariamente por tradição oral. As suas características vocais diferenciam-se das de outras regiões do país, embora se desconheçam ainda as razões fisiológicas e acústicas responsáveis por tal distinção. O presente trabalho propõe investigar a performance vocal das cantadeiras do Alto Minho numa perspetiva multidimensional, considerando aspetos sociais, culturais, fisiológicos e acústicos associados à prática deste estilo musical. Assim, os dados recolhidos, qualitativos e quantitativos, procuraram: (i) descrever práticas performativas atuais, (ii) explorar as perceções existentes sobre os traços mais relevantes da voz nesta região, (iii) investigar propriedades fisiológicas e acústicas da voz neste estilo, e (iv) comparar o canto folclórico do Alto Minho com outros estilos de canto tradicional. Foram envolvidos: 78 grupos, em questionários telefónicos, 13 diretores em questionários de caracterização performativa, 1 cantadeira num estudo piloto, 16 cantadeiras em gravações áudio preliminares, 77 membros de grupos folclóricos em testes perceptuais auditivos e 10 cantadeiras em gravações multicanal, incluindo sinais áudio, ELG, fluxo de ar e pressão intra-oral. A análise de dados incluiu análise temática de conteúdo, estatística descritiva e inferencial, análise hierárquica de componentes principais e modelos de regressão linear multivariada. As características vocais mais representativas incluem: voz aguda e forte, com timbre estridente, prevalência de registo de peito com nível não-excessivo de esforço, boa inteligibilidade do texto e sotaque da região. Poucas foram as cantadeiras identificadas como detentoras destas características. As que foram apontadas como possuidoras de vozes mais representativas apresentam valores de pressão subglótica e contacto das pregas vocais elevados, predominância de parciais harmónicos superiores e grande intensidade vocal, características que corroboram as associadas a uma fonação “pressionada”. Este padrão vocal, indicativo de esforço fonatório, aproxima-se do descrito em belting, utilizado em teatro musical. Quando comparado com outros géneros tradicionais, as cantadeiras do Alto Minho apresentam alguns traços semelhantes aos dos cantores de country (EUA) e ojikanje (Croácia). Estratégias que poderão contribuir para a preservação deste estilo vocal e para a saúde vocal das cantadeiras apontam para a formação contínua de grupos existentes, à semelhança do que acontece com outros estilos folclóricos europeus.

Este trabalho enfatiza o desenvolvimento de uma unidade retificadora em alta freqüência para aplicação em centrais telefônicas com capacidade de 1500W. O retificador é composto por um estágio pré-regulador de fator de potência com correção ativa e um outro estágio formado por um conversor CC/CC para isolar e adequar o nível da tensão de saída. A correção ativa é realizada por um conversor BOOST operando em condução contínua, modulador por largura de pulso com controle por corrente média e comutação sob tensão nula (BOOST-HPF-CCM-PWM-ZVS), proporcionando fator de potência praticamente unitário pela baixa distorção harmônica da corrente drenada da rede. O conversor CC/CC é formado pela topologia em ponte completa com comutação sob tensão nula, modulado por largura de pulso e controlado por deslocamento de fase (FB-ZVS-PWM-PS). Para possibilitar o paralelismo entre as unidades retificadoras realiza-se o controle pelo modo corrente deste conversor, permitindo distribuição uniforme da corrente de carga entre as unidades. Baixo peso e volume, compatibilidade de custo e baixos níveis de interferência são características da estrutura proposta.

Esta pesquisa de caráter qualitativo exploratório objetivou investigar a construção da expertise entre clarinetistas brasileiros. Teve como objetivos investigar os fatores determinantes para a construção da expertise na performance dos participantes, analisando as estratégias de gerenciamento, manutenção e regulação de suas performances. A revisão de literatura considerou quatro eixos de análise: 1) motivação, 2) autorregulação, 3) metacognição e 4) prática deliberada. Como estratégia metodológica utilizou-se a entrevista semiestruturada a partir das quais foram entrevistados quatro clarinetistas experts de orquestras sinfônicas brasileiras. Os resultados indicam que a performance expert pode ser construída por meio do refinamento dos processos cognitivos envolvidos na preparação da própria performance. As análises fora realizadas a partir do diálogo entre as falas dos participantes e a literatura que indicou estratégias específicas dos clarinetistas na construção da sua expertise musical. A performance de alto nível pode ser construída a partir de estratégias metacognitivas autorreguladas de preparação, sendo a motivação considerada um elemento fundamental para sustentar o estudo efetivo a longo prazo e auxiliar na construção da expertise na clarineta. ____________________________________________________________________________ ABSTRACT
This qualitative exploratory research investigates the process of developing music expertise among Brazilian clarinet players. It look at the determinant factors for the construction of the expertise like strategies management and maintenance of quality music performances. The literature indicates four areas of analysis: 1) motivation , 2) self-regulation, 3) metacognition, and 4) deliberated practice. The data was collected through semi-structured interviews with four professional clarinet players that work in major symphony orchestras in Brazil. The results indicate that expert performance could be constructed by refinement of individual strategies during the process of performance readiness. The analysis was realized based on the dialogue between the subjects’ ideas and the music cognition literature. It is possible to observe that Brazilian clarinetists developed a series of strategies to achieve musical expertise.

Esta dissertação tem como objetivo avaliar o nível de Orientação Empreendedora das médias e grandes empresas com alta performance financeira, atuando no Estado da Bahia, no período de 1997 a 2001. A metodologia utilizada para avaliar a orientação empreendedora envolveu análises teóricas e empíricas, chegando-se a conclusão que os modelos analisados apresentavam muitas limitações. Foi construído, então, um novo modelo de análise que abordasse a natureza multifacetada desse fenômeno e atendesse às especificidades da pesquisa. O modelo utilizado define a Orientação Empreendedora sob à luz de três dimensões sínteses: inovação, proatividade e propensão a riscos. Essas dimensões foram desdobradas em indicadores compostos, que compõem as funções inovação f(INO), proatividade f(PRO) e propensão a riscos f(PRS), que, com seus pesos específicos, definem a função geral da Orientação Empreendedora e seus diversos níveis. A partir deste modelo, tendo como elementos de referência dados quantitativos de pesquisas nacionais sobre o tema, desenvolveu-se uma pesquisa do tipo survey, com base em técnicas de pesquisa qualitativa e quantitativa, envolvendo uma amostra probabilística de 16 empresas, selecionadas das 94 que obtiveram performance financeira diferenciadas no período. Este estudo concluiu que das empresas pesquisadas, ocorre uma tendência para inovação média-baixa, proatividade média-alta e propensão a riscos média-baixa. Do ponto de vista da Orientação Empreendedora, nenhuma empresa foi considerada com OE alta, 25,0% delas foram consideradas com OE média- alta, 68,7% obtiveram OE média- baixa e apenas 6,3% atingiu uma OE baixa. Nenhuma empresa foi considerada sem OE. Foi constatado, portanto, que empresas de alta performance financeira apresentam diferentes níveis de OE, na medida em que cada uma das dimensões apresente importância variada, esses níveis de OE devem-se às variações de combinações entre essas dimensões e que estas últimas oscilam por influência de muitas outras variáveis. Além do resultado apresentado, foram sinalizadas proposições de ações e uma agenda de pesquisa futura para o tema de Empreendedorismo Corporativo e Orientação Empreendedora no Estado da Bahia.

Full textThis work aims to investigate how are sustained the desires and intimacies of women who are responsible for their families and their children education and, nowadays are also responsible for business conducting in large enterprises in São Paulo. It seeks to understand the implications of business life in the intimacy of women, including their desires and pleasures. This objective is justified by the curiosity to understand how these women lead their personal lives at the same time as professional life, in a culture permeated by general male characteristics. Is it necessary to waive any behavior perceived as feminine to achieve positions of great responsibility? How they deal with a culture of increasing performance demand and (seemingly) endless? How they feel about their own families? To answer these questions, a diverse literature was used, since it passes through different academic areas Administration, Sociology, Psychology. In addition, interviews were conducted for the purpose of this study to become more complete and true to life. The results were enlightening, revealing and presenting a paradox that perhaps today is not so explicit to the women themselves, since they face the challenge of their own performing careers
Este trabalho objetiva investigar como se sustentam os desejos e intimidades de mulheres responsáveis por sua família e pela criação de seus filhos, e hoje ainda responsáveis pela condução de negócios em empresas de grande porte de SP. Procura compreender as implicações da vida empresarial na intimidade da mulher, inclusive em seus desejos e prazeres. Esse objetivo justifica-se pela curiosidade de compreender como essas mulheres conduzem sua vida pessoal concomitantemente à profissional, em uma cultura em geral permeada por características masculinas. É necessário abrir mão de algum comportamento entendido como feminino para alcançar cargos de grande responsabilidade? Como elas lidam com uma cultura de exigência performática cada vez maior e (aparentemente) sem fim? Como se sentem com relação às suas famílias? Para responder a essas perguntas foi utilizada uma bibliografia diversificada, já vez que o assunto perpassa diferentes áreas acadêmicas Administração, Sociologia, Psicologia. Além disso, foram realizadas entrevistas para que o objetivo deste estudo se tornasse mais completo e fiel à realidade. Os resultados obtidos foram enriquecedores, reveladores e portadores de um paradoxo que talvez hoje não esteja tão explícito para as próprias mulheres, uma vez que elas mesmas enfrentam o desafio de uma carreira performática

Full textThe present work provides an overview of use and design of columns made with high performance concrete (HPC), whose main analyzed attribute is the compression strength of the concrete. The emphasis of the study is given to the application of HPC in columns of buildings. The main differences are presented among columns of HPC and columns made with low strength concrete (fck < 40 MPa), being approached, on base in effective codes and in experimental results, the more suitable stress-strain diagrams, the forms of consideration of the physical and geometrical non-linearities, the eccentricities to be considered in the design, the causes and the form of prevention of the phenomenon of the spalling of the concrete cover (characteristic of HPC columns), the importance and the form of consideration of the confinement and some necessary constructive dispositions for the good performance of the column. It was sought, whenever possible, to present the aspects that don\'t need alterations, that is to say, that can be considered in the same way for low and high strength concretes. It concludes with the presentation of some examples of design of HPC columns, approaching the topics analyzed along the text.

Full textThe present study aims to characterize the dynamics of stiffness and biomechanical parameters related to stiffness (BPRS) in male and female athletes during top speed short distance run. It also intends to investigate possible performance discriminative factors and their relation with jumping tasks frequently used in training. For this purpose, two studies have been developed. Study 1 has characterized the dynamics of the biomechanical parameters related to stiffness and indicated possible discriminative factors (by gender). The study 2 has related these possible discriminative factors with jumping. The \'Spring Mass Model\' has been used to obtain the BRPS and the force plate (AMTI) and cinemetry (VICON) have been used to acquire jumping data. The study showed that stiffness has not presented total convergence with velocity dynamics and the vertical force applied to the ground during the support phase has been the closest result to the velocity dynamics presented. There has not been distinctions regarding gender in stiffness and BRPS dynamics, however, females have showed more dependency on step timing parameters on the test beginning and muscle complacency at the end of the test; and males presented more dependency on to the vertical force applied to the ground during the support phase on the test beginning and parameters connected to the increase in the swing phase at the end test. Moreover, there has been a difference with statistical significance between genders regarding magnitude and contribution through the running phases. In additional, the horizontal jump (HJ) results represented a closer relation to the performance top speed short distance run. Therefore, it has been concluded that 1) stiffness itself cannot explain the performance in top speed short distance run, 2) among the BRPS, vertical force magnitude applied to the ground during support phase presents closer results to velocity dynamics, 3) males and females depend on distinct BRPS to enrich their performance and 4) HJ is the exercise with the major validity to be used for the evaluation and training routine of top speed short distance run athletes

Full textThe use of high performance concrete is an irreversible tendency in structural design due to the advantages it presents, compared to the concrete of usual strength, these advantages can be seen mainly in the execution of buildings columns as the cross sections can be reduced. This thesis is about the theoretical and experimental study to obtain high performance concrete columns. The behaviour of models subjected to axial load and bending plus axial load was analysed. Columns with the square (20cm x 20cm) and rectangular (15cm x 30cm and 12cm x 30cm) cross sections were studied, because they are the usual buildings columns dimensions. As far as axial load is concerned, the ultimate state limit was reached when the mostly demanded section broke. It was proven that the rupture occurred when the core, defined by the perimeter considered by the axial stirrups, broke. The results of bending plus axial load tests have shown that the distribution of stress hypotheses used for concrete of usual strength must not be considered for high strength concrete. The experimental axial forces and the internal ones calculated by a given model were the same, whereas the experimental values for the internal moments were much higher.

Full textThis work provides an overview of use and design of the high performance concrete (HPC) flexural members, reinforced or prestressed, with particular attention for the last ones. Cases in which procedures of the modern codes for calculation of HPC beams remain valid were enhanced. In the introduction, the economic viability of high performance concrete beams is presented. In the chapter about shrinkage and creep, valid procedures for HPC are presented. These procedures have better correlation with the actual results than those relative to ACI 209 (1982) or CEB-FIP (1990). A rectangular stress block is presented, and its results for usual and high performance concrete are compared with those from the parabolic-rectangular stress block, in terms of consume of steel. In the chapter about shear, recommendations for use of Standard Method and Variable Angle Truss Model for HPC beams are presented. For the calculation of short term deflections, the validity of Branson\'s Method for high performance concrete beams is confirmed. Sustained load deflections are also considered, and including procedures for reinforced beams and for precast prestressed ones. For all the considered topics, examples are presented for a 30 m span precast post-tensioned beam, \"T\" cross section and fck = 70 MPa.

Full textA distribui ção de um sinal relógio, com elevada precisão espacial (baixo skew) e temporal (baixo jitter ), em sistemas sí ncronos de alta velocidade tem-se revelado uma tarefa cada vez mais demorada e complexa devido ao escalonamento da tecnologia. Com a diminuição das dimensões dos dispositivos e a integração crescente de mais funcionalidades nos Circuitos Integrados (CIs), a precisão associada as transições do sinal de relógio tem sido cada vez mais afectada por varia ções de processo, tensão e temperatura. Esta tese aborda o problema da incerteza de rel ogio em CIs de alta velocidade, com o objetivo de determinar os limites do paradigma de desenho sí ncrono. Na prossecu ção deste objectivo principal, esta tese propõe quatro novos modelos de incerteza com âmbitos de aplicação diferentes. O primeiro modelo permite estimar a incerteza introduzida por um inversor est atico CMOS, com base em parâmetros simples e su cientemente gen éricos para que possa ser usado na previsão das limitações temporais de circuitos mais complexos, mesmo na fase inicial do projeto. O segundo modelo, permite estimar a incerteza em repetidores com liga ções RC e assim otimizar o dimensionamento da rede de distribui ção de relógio, com baixo esfor ço computacional. O terceiro modelo permite estimar a acumula ção de incerteza em cascatas de repetidores. Uma vez que este modelo tem em considera ção a correla ção entre fontes de ruí do, e especialmente util para promover t ecnicas de distribui ção de rel ogio e de alimentação que possam minimizar a acumulação de incerteza. O quarto modelo permite estimar a incerteza temporal em sistemas com m ultiplos dom ínios de sincronismo. Este modelo pode ser facilmente incorporado numa ferramenta autom atica para determinar a melhor topologia para uma determinada aplicação ou para avaliar a tolerância do sistema ao ru ído de alimentação. Finalmente, usando os modelos propostos, são discutidas as tendências da precisão de rel ogio. Conclui-se que os limites da precisão do rel ogio são, em ultima an alise, impostos por fontes de varia ção dinâmica que se preveem crescentes na actual l ogica de escalonamento dos dispositivos. Assim sendo, esta tese defende a procura de solu ções em outros ní veis de abstração, que não apenas o ní vel f sico, que possam contribuir para o aumento de desempenho dos CIs e que tenham um menor impacto nos pressupostos do paradigma de desenho sí ncrono.
Distributing a the clock simultaneously everywhere (low skew) and periodically everywhere (low jitter) in high-performance Integrated Circuits (ICs) has become an increasingly di cult and time-consuming task, due to technology scaling. As transistor dimensions shrink and more functionality is packed into an IC, clock precision becomes increasingly a ected by Process, Voltage and Temperature (PVT) variations. This thesis addresses the problem of clock uncertainty in high-performance ICs, in order to determine the limits of the synchronous design paradigm. In pursuit of this main goal, this thesis proposes four new uncertainty models, with di erent underlying principles and scopes. The rst model targets uncertainty in static CMOS inverters. The main advantage of this model is that it depends only on parameters that can easily be obtained. Thus, it can provide information on upcoming constraints very early in the design stage. The second model addresses uncertainty in repeaters with RC interconnects, allowing the designer to optimise the repeater's size and spacing, for a given uncertainty budget, with low computational e ort. The third model, can be used to predict jitter accumulation in cascaded repeaters, like clock trees or delay lines. Because it takes into consideration correlations among variability sources, it can also be useful to promote oorplan-based power and clock distribution design in order to minimise jitter accumulation. A fourth model is proposed to analyse uncertainty in systems with multiple synchronous domains. It can be easily incorporated in an automatic tool to determine the best topology for a given application or to evaluate the system's tolerance to power-supply noise. Finally, using the proposed models, this thesis discusses clock precision trends. Results show that limits in clock precision are ultimately imposed by dynamic uncertainty, which is expected to continue increasing with technology scaling. Therefore, it advocates the search for solutions at other abstraction levels, and not only at the physical level, that may increase system performance with a smaller impact on the assumptions behind the synchronous design paradigm.

Neste trabalho, intitulado Construções biográficas pelas canções populares, discute-se a potência das canções em ler marcas inscritas e reescritas na história de muitas vozes e em produzir memórias biográficas. Dividido em três capítulos, privilegia-se, do ponto de vista metológico, a força da canção e as experiências e vivências do autor com o alto-falante, com o seu fazer artístico e, por fim, com o seu trabalho de professor, embora outros autores sejam convidados a participarem do debate. No capítulo inicial, amparando-se em imagens produzidas por compositores da música popular brasileira, discute-se o alto-falante como símbolo das culturas de massa e como “casulo da canção”, produtor de uma estética musical própria, bem como a sua importância na produção de registros nos corpos dos sujeitos, através de uma síntese histórica do rádio, da memória do Serviço de Alto-falante A Voz do Povo e, por fim, das novas feições assumidas pelo alto-falante, tomando como base as mudanças sociais ocorridas no país e as novas tecnológicas eletrônicas. No segundo capítulo, descreve-se e analisa-se todo o processo de construção e apresentação do espetáculo Mar Noturno e a sua implicação com o ato da narrativa, com as canções de alto-falante e com as memórias afetivas do autor, ressaltando o seu caráter performático e autobiográfico. No terceiro capítulo apresenta-se uma proposta metodológica, voltada para a auto-formação e inserção de vozes,que tem como ponto de partida as canções que marcaram as histórias dos sujeitos. A referida proposta, que recebe o nome de Ateliês de performances biográficas pelas canções populares, testada e desenvolvida no Centro de Estudos e Assessoria Pedagógica – CEAP, é discutida através de um amplo painel de depoimentos dos membros da equipe e das próprias canções, que dialoga com vozes de autores diversos. Nos três capítulos, outros teóricos são convidados para participar das discussões. Entre eles, destacam-se José Miguel Wisnik (2004, 1989), Giorgio Agamben (2009), Leonor Arfuch (2010, 2012) e Delory-Momberger (2008, 2010). O primeiro dá suporte às discussões sobre a potência da canção e o seu uso no contexto sóciopolítico-cultural brasileiro. O segundo ampara o debate sobre a canção como dispositivo. O mesmo acontece com Arfuch (2012), quando se discute a ideia de antibiografia. Essa autora contribui, também, juntamente com outros nomes, com as discussões sobre temas pertinentes aos espaços biográficos. Já Delory-Momberger (2008, 2010), além de inspirar a proposta dos ateliês, participa das trocas a respeito da memória biográfica. Quanto às narrativas como ato performático, recorre-se às discussões feitas por Cohen (2011), Zumthor (2010) e Person (1999). Nomes como Foucault (2006, 1992) e Barthes (2005, 1993), entre outros, perpassam essas discussões. Por fim, nas considerações finais, reflete-se sobre o cumprimento dos objetivos e as dificuldades encontradas ao longo do percurso, identificam-se novas demandas, ganhos e achados, e conclui-se com a compreensão de que esta tese trata de um processo, de um exercício quase auto-biográfico, que ultrapassa discussão musical, embora o seu fio condutor seja a potência das canções em produzir novas subjetividades e inserção de vozes.

Resumo: Apresenta-se, neste trabalho, o estudo desenvolvido sobre o fenômeno da aderência em Concretos de Alto Desempenho, através de ensaios à flexão de vigas de concreto armado com CAD. A aderência foi analisada sob os aspectos de ancoragem e fissuração na região das barras longitudinais emendadas por transpasse. Os modelos das vigas ensaiadas foram de três tipos, conforme a maneira em que as barras foram transpassadas. Para cada modelo, foram avaliados os parâmetros de: resistência do concreto, diâmetro das barras, comprimento de emenda, cobrimentos das barras e o comportamento das variadas emendas. Os resultados foram, ainda, analisados com as equações internacionais para predição da aderência e com a NBR 6118:2003
Abstract: This paper presents the study about the bond phenomenon in High Performance Concrete, through the analisys of the flexibility of reinforced concrete beams with HPC. The bond was analyzed under the anchorage and cracking aspects, on longitudinal bars part spliced by transfix. Three types of beam models were analyzed, according to the manner which they were transfixed. For each model, the parameters adopted were: concrete strength, bar diameter, development lengths, cover of the bars and the behavior of the various splices. The results were also analyzed with the international equations for the bond prediction and NBR 6118:2003

Full textRefatoração é uma técnica de engenharia de software que consiste em alterar a estrutura interna de uma aplicação sem que tais alterações interfiram nos resultados produzidos pela mesma. Trata-se de uma tarefa permanentemente presente no ciclo de vida de uma aplicação e está diretamente associada às características não funcionais do software, como legibilidade e desempenho. Técnicas de refatoração são amplamente utilizadas em sistemas desenvolvidos para o paradigma da orientação a objetos e estão presentes de forma automatizada em diversas ferramentas que atuam neste paradigma. Na computação de alto desempenho, a refatoração de código é pouco explorada, principalmente em função de que boa parte do código legado de programas de alto desempenho está escrita em linguagens anteriores ao paradigma da orientação a objetos. A linguagem Fortran (FORmula TRANslator), largamente utilizada em aplicações de alto desempenho, possui poucas e limitadas ferramentas para refatoração de código. Neste contexto, este trabalho explora essa deficiência através da automatização de técnicas de refatoração, utilizando-se do framework da ferramenta Photran (um plugin para edição de código Fortran integrado ao IDE Eclipse). Partindo-se da identificação de oportunidades de refatoração para código Fortran, algumas técnicas são desenvolvidas e integradas à ferramenta Photran. As técnicas automatizadas são utilizadas em aplicações escritas nesta linguagem, de forma a avaliar seu impacto no desempenho das mesmas.

Full textCloud computing is a new paradigm, where computational resources are offered as services. In this context, the user does not need to buy infrastructure, the resources can be rented from a provider and used for a period of time. Furthermore the user can easily allocate as many resources as needed, and deallocate them as well, in a totally elastic environment. The resources need to be paid only for the effective usage time. On the other hand, High-Performance Computing (HPC) requires a large amount of computational power. To acquire systems capable for HPC, large financial investments are necessary. Apart from the initial investment, the user must pay the maintenance costs, and has only limited computational resources. To overcome these issues, this thesis aims to evaluate the cloud computing paradigm as a candidate environment for HPC. We analyze the efforts and challenges for porting and deploy HPC applications to the cloud. We evaluate if this computing model can provide sufficient capacities for running HPC applications, and compare its cost efficiency to traditional HPC systems, such as clusters. The cloud computing paradigm was analyzed to identify which models have the potential to be used for HPC purposes. The identified models were then evaluated using major cloud providers, Microsoft Windows Azure, Amazon EC2 and Rackspace and compare them to a traditional HPC system. We analyzed the capabilities to create HPC environments, and evaluated their performance. For the evaluation of the cost efficiency, we developed an economic model. The results show that all the evaluated providers have the capability to create HPC environments. In terms of performance, there are some cases where cloud providers present a better performance than the traditional system. From the cost perspective, the cloud presents an interesting alternative due to the pay-per-use model. Summarizing the results, this dissertation shows that cloud computing can be used as a realistic alternative for HPC environments.

Full textLoad balance is essential for parallel applications to perform at their highest possible levels. As parallel systems grow, the cost of poor load distribution increases in tandem. However, the dynamic behavior the distribution of load possesses in certain applications can induce disparities in computational loads among resources. Therefore, the process of repeatedly redistributing load as execution progresses is critical to achieve the performance necessary to compute large scale problems with such characteristics. Metrics quantifying the load distribution are an important facet of this procedure. For these reasons, measures commonly used as load distribution indicators in HPC applications are investigated in this study. Considering the dynamic and recurrent aspect in load balancing, the investigation examines how these metrics quantify load distribution at regular intervals during a parallel application execution. Six metrics are evaluated: percent imbalance, imbalance percentage, imbalance time, standard deviation, skewness, and kurtosis. The analysis reveals the virtues and deficiencies each metric has, as well as the differences they register as descriptors of load distribution progress in parallel applications. As far as we know, an investigation as the one performed in this work is unprecedented.

O trabalho de campo foi realizado na comunidade, no período de novembro 2010 a fevereiro de 2011, com o intuito de ouvir e registrar em vídeo e em áudio as histórias de vida, sobre fatos e pessoas conhecidas ou que viveram no lugar. A partir da convivência com os sujeitos, idosos, moradores da zona rural registrei também os modos de vida, saberes e fazeres da comunidade. Após a realização do trabalho de campo, utilizei-me dos registros e da observação local, para análise do conteúdo das narrativas e da performance dos narradores durante o evento. Neste sentido, valeu-me também os aportes teóricos e a convivência anterior com a comunidade. Diante disso, posso afirmar que as narrativas orais expressam a história coletiva e individual dos sujeitos. Em suas performances eles nos apresentam as suas singularidades, expressas nos gestos, na fala, na postura, que também tem uma relação com o contexto em que vivem.
This is the study of orality and performance of the residents of the rural community Morro Alto, located in the municipality of Bocaiuva-MG. The fieldwork was carried out in the community from October 2010 to February 2011 in order to hear and video and audio record the stories of life, facts and people known or who lived in the place. From the interaction with the citizens, elderly, rural area residents it was also recorded ways of life, knowledge and practices in the community. After accomplishment of field work, it was used records and observation on site to analyze the content of narratives and narrators performance during the event. In this sense, it was also used the earlier theoretical contributions and the coexistence with the community. Thus, it can be stated that the oral narratives express the collective and individual history of the subjects. In their performances were presented their singularities, expressed in gestures, speech, posture, and it also has a relation to the context in which they live.

Resumo: Este trabalho considera o projeto, análise e controle de um reator heterogêneo enzimático de tubo aberto (RHETA), designado por sistema médico, cujo intuito é sua utilização no tratamento extracorporal de leucemia linfoblástica aguda em crianças, bem como sua extensão para outros tipos de terapia extracorporais. O tratamento extracorporal por meio de tubos catalíticos é de grande importância para uso em sistemas médicos, pois permite que as reações sejam realizadas fora do organismo vivo, sem a necessidade de se introduzir o agente terapêutico (isto é, a enzima) na circulação sistêmica, o que pode causar uma série de reações colaterais indesejáveis ao paciente. Além disso, não há perdas da enzima. Inicialmente, o projeto e análise do reator foi considerado. Para isto, foi desenvolvido um modelo matemático bidimensional representativo do sistema real, através da aplicação de balanços de massa e energia, resultando num sistema de equações diferenciais parciais não lineares. A solução deste sistema foi obtida através de um procedimento numérico baseado no método das diferenças finitas. Isto permitiu o projeto ótimo do reator onde se aplicou a metodologia de superfície de resposta. Tendo sido projetado o reator, foi efetuado uma análise de sensibilidade paramétrica considerando-se 4 variáveis operacionais importantes. Para isto, foi aplicado um delineamento fatorial de '2 POT. 4¿ e os resultados foram analizados por técnicas estatísticas, o que permitiu que se pudesse verificar amplamente os efeitos de cada variável sobre a eficiência do reator, sua estabilidade e conversão...

Abstract: This work deals with the design of an open tubular heterogeneous enzimatic reactor (OTHER), a medical system, which is used in the extracorporeal Acute Linphoblastic Leukaemia tretment, as well as others extracorporeal therapies. The use of such methods shows great potential for medical therapies because it allows enzyme reactions to be carried out of a living system without the need to introduce the terapeutic agent into the systemic circulation. Moreover, there is no enzyme loss. Firstly, a mathematical model was developed to represent the real system, resulting in a system of non linear partial diferential equation. A numerical procedure based on finite diference method was applied to solve the proposed model. By use of the surface response method, the simulation of the model has resulted in an optimum reactor project. A parametric sensitivity analysis was made using a '2 POT. 4¿ factorial design and statistical analysis from which was possible to verify the effect of the variables on the reactor efficiency, stability and conversion. Also, the interactions between variables were analysed. A modified Thiele modulis was defined and the reactor performance was studied when operating under mass transfer and kinetics conditions. The reactor dynamic shows no wrong way behaviour... Note: The complete abstract is available with the full electronic digital thesis or dissertations

Full textParallel computing has become an essential tool to achieve the performance needed by many scientific applications. The evaluation of performance factors of parallel applications is of utmost significant. This work presents the developement and implementation of a tool called Hierarchical Analyses which facilitates data collection for performance analysis of parallel programs with hierarchical information, i.e. the information is collected in the various abstraction levels used in the application program. The tool consists of a collection and a transformation modules. The collection module (HieraCollector) collects the data and stores it in XML format. The transformation module (HieraTransform) processes the collected data computing measurements to be used in the analysis of parallel code. To validate the tool, implementations adapted to MPI and the OOPS framework have been developed. Another contribution of this work is the development of a visual tool called HieraOLAP to help the user in the analysis of parallel program performance.

Full textFrom the rheological point of view, the fresh concrete flows as a liquid. In such case, its fresh behavior should be studied from the concepts of rheology, the science which concerns the study of deformation and flow of a fluid under stress influence. The well designed structures, depending on the process considered in their production, are performed in a very short time after the mixture of the materials that will constitute the concretes. Thus, the concrete workability is an important parameter to be studied, even for facilitating the material placement and for the decisions related with the method of this process. Traditionally, the concrete workability is associated to its consistency, expressed in terms of the slump value measured by the slump test that, in spite of being a quite used test, does not quantify it totally. It happens because the concrete behaves as a Bingham fluid, being described by two rheological parameters: the yield stress and the plastic viscosity. Thus, the present research determines some measure parameters from rheological concepts to verify the behavior of some types of fresh high performance concrete (with silica fume addition). For this, both traditional test methods - slump test and Vebe consistometer - and more recent equipments - rheometer - were used. A modification of the traditional slump test was also used as an attempt to simplify the determination of the rheological parameters that describe the fresh concretes behaviors. The capacity of the concretes flow under the influence of their own weight was evaluated by the L-box test. The identification of the concretes rheological behavior was made with a rheometer. The concretes workability was evaluated from test methods that measure the two rheological parameters and its loss over time was associated to the evolution of the measured parameters. In spite of being classified as fluid mixtures, none of the concretes presented enough flow to describe it as a self-compacting material; however they presented a good flow under vibration energy. The concrete rheological behavior was identified as being similar to a Bingham fluid. The workability, as its loss over time, was associated to the evolution of the rheological parameters: an increase of the yield stress (or flow resistance) was observed, while the plastic viscosity (or torque viscosity) stayed practically constant during the 60 minutes in which the behavior was followed. It is concluded that for the high performance concretes workability, there are other several important factors to be considered in the research pursuit, which should consider the parameters associated to the material\'s production, transport and placement.

The objective of this study was to evaluate the effect of two proportions of concentrate, 70 and 80%, with two energy sources, corn and corn germ meal, and roughage basis of corn silage on the intake of nutrients, performance, characteristics of a carcass, non components of carcass and meat quality of confined 28 Nellore heifers. The experimental design was a completely randomized design in factorial scheme 2 x 2 (2 proportions of concentrate x 2 energy sources) 4 replications and 7 treatments, and the averages has been compared by Tukey 5% test.. There was no interaction proportion of concentrate x energy source on the intake of dry matter. There was a significant effect of interaction proportion of concentrate x energy source intake for crude protein (CP) and neutral detergent fiber (NDF), suggesting that a higher proportion of concentrate, with the corn, allowed greater intake of CP (1.17 kg / day) and NDF (4,05 kg / day). It was observed average intake of acid detergent fiber than for diets with 80% concentrate, with both the diet with corn as the corn germ meal. There was a significant effect of dietary energy source on the final weight of animals, and the animals fed the diets with corn had average final weight (326.14 kg), above the fed with diets with corn germ meal (292.07 kg). The association of high proportions of concentrate with corn as an energy source, provided satisfactory results in performance of Nellore heifers, since the replacement of the corn germ meal, associated with high proportions of concentrate rich in fiber, not was recommended for young Nellore heifers. There was a significant effect the energy source of the diet on the weight of empty body, and the animals that received the diets with corn showed the average value of empty body weight (309.44 kg) than the diets of with corn germ meal (276.42 kg).

The objective of the study was to evaluate the effect of different proportions of high-level diets on finishing lambs in feedlot system on performance. However, there is no ingestive and physiological behavior, as well as carcass characteristics, quality physical and chemical characteristics of meat and production costs. For this purpose, whole corn grain associated with the protein-mineral-vitamin supplement was used in three proportions of concentrate: bulky (100%, 80:20 and 60:40%), a concentrated portion of the diet composed of 85 % of whole corn grain and 15% of supplement and bulky portion of Tifton hay). Twentyfour non-castrated males with no defined racial pattern were used with initial weight of 20.9 ± 1.0 kg at the age of 6 months. Weight gain was achieved in the three diets tested from 0.302g / day for 100% diet, 0.254g / day to 80:20 and 0.259g / day for 60:40 Minor rumination time (P≤0.05) in lambs of the treatment based on grain 100% when compared to the lambs of the other treatments. The 100% diet presented higher feed efficiency (EAL) and also more efficient rumination (ERU). Evaluating a temperature of the rumen region, it can be seen that the animals that received a 100% diet showed the variation of the temperature of the reen region, as 80:20 and 60: 40% diets affect nearby temperatures. As evaluated diets contributed to the performance with satisfactory gains, although preferences of use of diet of high grade, these guarantee like basic actions. There was a significant effect on carcass yield. A 100% concentrated diet showed a carcass yield of 47%, while for 80: 20% and 60: 40% diets obtained carcass yield values of 43.5% and 43.4%, respectively. The gastrointestinal content also had an effect, being lower in treatments 100% and 80: 20%. (P> 0.05) in the variables pH, temperature, color, water retention capacity and shear force. The 100% treatment presented a weight loss in cooking as well as superior thiobarbituric acid (TBARS) when compared with other diets. The 100% diet, when compared with other diets, obtained an additional carcass weight of 2.30 kg per animal. The use of the 100% concentrated diet in lamb termination systems is a more viable alternative from a productive and economical point of view
RESUMO: Objetivou-se com o estudo avaliar o efeito de diferentes proporções de dietas de alto grão na terminação de cordeiros em sistema de confinamento sobre o desempenho e alterações no comportamento ingestivo e fisiológico, assim como as características de carcaça, qualidade físicas e químicas da carne e custos de produção. Utilizou-se para tal, grão de milho inteiro associando ao suplemento protéico-mineral-vitamínico em três proporções de concentrado:volumoso, (100%, 80:20% e 60:40%), sendo a porção concentrada da dieta composta de 85% de grão de milho inteiro e 15% de suplemento e a porção volumosa de feno de Tifton). Foram utilizados 24 machos não castrados, sem padrão racial definido com peso inicial de 20,9 ± 1,0kg com idade de 6 meses. Conseguiu-se obter ganhos de peso nas três dietas testadas de 0,302g/dia para dieta 100%, 0,254 g/dia para 80:20 e 0,259 g/dia para 60:40 O tempo de ruminação foi menor (P≤0,05) nos cordeiros do tratamento à base de grão 100% quando comparados aos cordeiros dos demais tratamentos. A dieta 100% apresentou maior eficiência de alimentação (EAL) e também mais eficiente na ruminação (ERU). Avaliando a temperatura da região do rúmen percebe-se que os animais que receberam a dieta 100% apresentaram acentuada variação de temperatura da região do rémen, as dietas 80:20 e 60:40% apresentam alterações de temperaturas próximas. As dietas avaliadas contribuíram para o desempenho com ganhos satisfatórios, apesar de ocorrer alterações comportamentais com uso da dieta de alto grão, estas garantem as ações básicas necessária para manter a saúde ruminal adequada. Houve efeito significativo para rendimento de carcaça. A dieta 100% concentrado apresentou um rendimento de carcaça de 47%, enquanto as dietas 80:20% e 60:40% obtiveram valores para rendimento de carcaça de 43,5% e 43,4% respectivamente. O conteúdo gastrointestinal também apresentou efeito, sendo menor nos tratamentos 100% e 80:20%. Para os parâmetros físicos da carne, não foi observado diferenças significativa (P>0,05) nas variáveis pH, temperatura, cor, capacidade de retenção de água e força de cisalhamento. O tratamento 100% apresentou uma menor perda de peso na cocção assim como também apresentou ácido tiobarbitúrico (TBARS) superior quando comparado as demais dietas. A dieta 100%, quando comparado as demais dietas, obteve-se um peso adicional de carcaça de 2,30 Kg por animal. O uso da dieta 100% concentrado em sistemas de terminação de cordeiros é a alternativa mais viável do ponto de vista produtivo e econômico

O volume, a variedade e a velocidade dos dados apresenta um grande desa o para extrair informações úteis em tempo hábil, sem gerar grandes impactos nos demais processamentos existentes nas organizações, impulsionando a utilização de clusters para armazenamento e processamento, e a utilização de computação em nuvem. Este cenário é propício para o Hadoop, um framework open source escalável e e ciente, para a execução de cargas de trabalho sobre Big Data. Com o advento da computação em nuvem um cluster com o framework Hadoop pode ser alocado em minutos, todavia, garantir que o Hadoop tenha um desempenho satisfatório para realizar seus processamentos apresenta vários desa os, como as necessidades de ajustes das con gurações do Hadoop às cargas de trabalho, alocar um cluster apenas com os recursos necessários para realizar determinados processamentos e de nir os recursos necessários para realizar um processamento em um intervalo de tempo conhecido. Neste trabalho, foi proposta uma abordagem que busca otimizar o framework Hadoop para determinada carga de trabalho e estimar os recursos computacionais necessário para realizar um processamento em determinado intervalo de tempo. A abordagem proposta é baseada na coleta de informações, base de regras para ajustes de con gurações do Hadoop, de acordo com a carga de trabalho, e simulações. A simplicidade e leveza do modelo permite que a solução seja adotada como um facilitador para superar os desa os apresentados pelo Big Data, e facilitar a de nição inicial de um cluster para o Hadoop, mesmo por usuários com pouca experiência em TI. O modelo proposto trabalha com o MapReduce para de nir os principais parâmetros de con guração e determinar recursos computacionais dos hosts do cluster para atender aos requisitos desejados de tempo de execução para determinada carga de trabalho. _______________________________________________________________________________ ABSTRACT
The volume, variety and velocity of data presents a great challenge to extracting useful information in a timely manner, without causing impacts on other existing processes in organizations, promoting the use of clusters for storage and processing, and the use of cloud computing. This a good scenario for the Hadoop an open source framework scalable and e cient for running workloads on Big Data. With the advent of cloud computing one cluster with Hadoop framework can be allocated in minutes, however, ensure that the Hadoop has a good performance to accomplish their processing has several challenges, such as needs tweaking the settings of Hadoop for their workloads, allocate a cluster with the necessary resources to perform certain processes and de ne the resources required to perform processing in a known time interval. In this work, an approach that seeks to optimize the Hadoop for a given workload and estimate the computational resources required to realize a processing in a given time interval was proposed. The approach is based on collecting information, based rules for adjusting Hadoop settings for certain workload and simulations. The simplicity and lightness of the model allows the solution be adopted how a facilitator to overcome the challenges presented by Big Data, and facilitate the use of the Hadoop, even by users with little IT experience. The proposed model works with the MapReduce to de ne the main con guration parameters and determine the computational resources of nodes of cluster, to meet the desired runtime for a given workload requirements.

Diversos relatos a respeito da ocorrência de experiências profundas e marcantes durante o fazer musical são narrados constantemente por muitos músicos, ao longo de suas carreiras, sendo objeto de estudo de variados campos do saber há pelo menos 5 décadas, além de constituir alvo da busca de muitas pessoas que se envolvem com a música de alguma forma. A maneira pela qual essas experiências são percebidas, compreendidas e construídas por pianistas de alto desempenho, suas características e seu significado intrínseco compõem o objetivo deste estudo exploratório. Através do relato de dois grandes nomes do piano internacional a respeito deste tema buscou-se entender como é possível chegar a este nível de experiência musical. A utilização do recurso da entrevista semiestruturada em profundidade foi fundamental para a obtenção dos dados que compuseram o objeto final deste trabalho, em virtude de seu molde flexível, que permite uma inserção mais livre e aberta no mundo do informante, proporcionando maior riqueza de material a ser analisado. A metodologia utilizada para o levantamento e análise dos dados foi o estudo de entrevistas, tendo como modelo a proposta da Entrevista Compreensiva, delineada por Kaufmann (2011). Os conceitos trazidos pela revisão de literatura foram elementos norteadores da pesquisa e delimitadores do termo central utilizado nesta pesquisa.
Several accounts regarding incidence of profound and remarkable experiences while making music are constantly reported by many musicians throughout their careers, being object of study of various fields of knowledge for at least 5 decades, besides constituting search target of many people who engage with music in some way. The way in which these experiences are realized, understand and built by high performance pianists, the characteristics and their intrinsic significance set the objective of this exploratory study. Through the story of two great names of the international piano about this issue, it was sought to understand how is it possible to achieve this level of musical experience. The use of the resource of in-depth semi-structured interview was fundamental for obtaining data that composed the final object of this work, by virtue of its flexible form, that allows a freer and opener insertion in the world of the insider, providing larger richness of the material to be analyzed. The methodology used for the data collection and analysis was the interview study, taking as template of work the proposal of the Comprehensive Interview, delineated by Kaufmann (2013). The concepts brought by the literature review were the guiding elements of the research and delimiters of the use of the central term.

Full textComputação de Alto Desempenho (CAD) agrega poder computacional com o objetivo de solucionar problemas complexos e de grande escala em diferentes áreas do conhecimento, como ciência e engenharias, variando desde aplicações medias 3D ate a simulação do universo. Atualmente, os usuários de CAD podem utilizar infraestruturas de Nuvem como uma alternativa de baixo custo para a execução de suas aplicações. Apesar de ser possível utilizar as infraestruturas de nuvem como plataformas de CAD, muitas questões referentes as sobrecargas decorrentes do uso de virtualização permanecem sem resposta. Nesse trabalho foi analisado o desempenho de algumas ferramentas de virtualização - Linux Containers (LXC), Docker, VirtualBox e KVM – em atividades de CAD. Durante os experimentos foram avaliados os desempenhos da UCP, da infraestrutura de comunicação (rede física e barramentos internos) e de E/S de dados em disco. Os resultados indicam que cada tecnologia de virtualização impacta diferentemente no desempenho do sistema observado em função do tipo de recurso de hardware utilizado e das condições de compartilhamento do recurso adotadas.
High Performance Computing (HPC) aggregates computing power in order to solve large and complex problems in different knowledge areas, such as science and engineering, ranging from 3D real-time medical images to simulation of the universe. Nowadays, HPC users can utilize virtualized Cloud infrastructures as a low-cost alternative to deploy their applications. Despite of Cloud infrastructures can be used as HPC platforms, many issues from virtualization overhead have kept them almost unrelated. In this work, we analyze the performance of some virtualization solutions - Linux Containers (LXC), Docker, VirtualBox and KVM - under HPC activities. For our experiments, we consider CPU, (physical network and internal buses) communication and disk I/O performance. Results show that different virtualization technologies can impact distinctly in performance according to hardware resource type used by HPC application and resource sharing conditions adopted.

Full textThis work proposes an advanced analysis for MLP performance improvement by adopting new target vectors. Firstly, a mathematical study is done to evaluate the influence of VBOs used as target vectors on MLP training. The VBOs provide the largest possible Euclidean distance between them to improve the training and generalization capability of MLPs. The largest distance inducement between points from output space leads to direct correspondence on pattern classification improvement. The various types of target vectors such as VBNs, VBCs and VNOs are adopted for training of MLP models and their performances are compared with the model trained by using VBOs. The mathematical evidences of performance improvement were found on weight updating refinement from backpropagation error stage of the algorithm. This particular refinement for training with VBOs is useful to preserve the features of each pattern due to noise interference reduction during the training process from a pattern to another. Following the mathematical study, more advanced experimental analysis using VBOs with two databases for pattern recognition is performed. The first database is related to the handwritten digits for comparing the performances of MLPs trained by adopting VBCs and VNOs with the performance of MLP trained by adopting VBOs. The results showed higher classification rates for the MLP trained with VBOs. The second database is constituted by human iris images in order to perform the comparison of MLP performances using conventional target vectors and new target ones represented by VBOs. Besides the high performance of MLPs trained with VBOs on recognition rates, it was concluded that the use of new target vectors provides high recognition rates with low tolerance for epoch trainings leading to the consequent low computational load for pattern processing.
O presente trabalho propõe a análise avançada para a melhoria de desempenho de MLP através do uso de novos vetores-alvo. Primeiramente, por meio de um estudo matemático, avalia-se a influência dos VBOs sobre o treinamento das MLPs quando são utilizados como vetores-alvo. Os VBOs possuem a maior distância euclidiana possível entre si, o que leva a supor que melhora o treinamento e a capacidade de generalização da rede em teste. A hipótese é a de que a provocação de uma maior distância entre os pontos de saída da rede pode ter relação direta com a melhoria na classificação dos padrões. Os diferentes tipos de vetores-alvo tais como VBNs, VBCs e VNOs são utilizados para o treinamento de MLPs e os seus desempenhos são comparados com a rede treinada adotando-se os VBOs. As evidências matemáticas da melhoria de desempenho foram encontradas no refinamento da atualização dos pesos, etapa denominada no algoritmo como retro propagação do erro. Esse refinamento característico do treinamento com VBOs age no sentido de preservar as características de cada padrão, reduzindo o ruído de interferência do treinamento de um padrão para outro. Seguindo-se ao estudo matemático, realiza-se uma análise experimental mais avançada da utilização dos VBOs por meio de duas bases de dados para reconhecimento de padrões. A primeira base de dados é a de dígitos manuscritos para comparar os desempenhos de MLPs treinadas com VBCs e VNOs com aquelas treinadas com VBOs. Os resultados mostraram taxas de classificação superiores para a MLP treinada com VBOs. A segunda base de dados é formada por imagens de íris humana com o propósito de realizar a comparação dos desempenhos de MLPs treinadas com vetores-alvo convencionais e novos vetores-alvo representados pelos VBOs. Além da alta performance nas taxas de reconhecimento das MLPs treinadas com VBOs, observou-se que com o uso desses novos vetores-alvo, é possível obter elevadas taxas de reconhecimento com pouco rigor nas épocas de treinamento, reduzindo-se consequentemente a carga computacional de processamento dos padrões.

Full textIn 2014, the creation of High Performance Schools (COAR) was promoted, with the aim of carrying out a quality education to all regions of Peru and especially to populations with fewer resources. It's like that, since it's about getting a management for a department. In this way, the initiative to develop the COAR of the Amazon Region was born, in response to a demand for infrastructure, and that students currently live in an improvised environment, within a technological environment. The following project is planned to be executed in the district of Lamud, province of Luya. Which consists of a residence for just over three hundred students, a classroom that consists of twelve sections, four laboratories, two computer rooms and a resource center for learning, a sports center with a swimming pool Multilaportive activities, recreational areas and all the facilities of this type of building for the proper functioning and stay of the main users, students and teachers. In addition, it can become a milestone in the area, in the area of recreation areas, sports and quality public spaces; provided to the city various places for the interaction of citizens, recreation spaces for children, parking lots for cars and bicycles, among others. The help services of the city.
