    Ganga provides a uniform interface for running ATLAS user analyses on a number of local, batch, and grid backends. PanDA is a pilot-based production and distributed analysis system developed and used extensively by ATLAS. This work presents the implementation and usage experiences of a PanDA backend for Ganga. Built upon reusable application libraries from GangaAtlas and PanDA, the Ganga PanDA backend allows users to run their analyses on the worldwide PanDA resources, while providing the ability for users to develop simple or complex analysis workflows in Ganga. Further, the backend allows users to submit and manage 'personal' PanDA pilots: these pilots run under the user's grid certificate and provide a secure alternative to shared pilot certificates while enabling the usage of local resource allocations.

  5. AS INTERFACES DA TEOLOGIA COM A BIOÉTICA

    Directory of Open Access Journals (Sweden)

    José Roque Junges

    2005-01-01

    Full Text Available Nos primórdios da bioética os teólogos desempenharam um papel importante no seu surgimento, devido à experiência na argumentação ética para solucionar casos e, especificamente, devido à tradição de intervenções em ética médica. Posteriormente houve um movimento de independência dos bioeticistas em relação aos teólogos, acentuando a secularização e o pluralismo da reflexão bioética. Isso obrigou os teólogos, que não deixaram de marcar presença, a explicitar a sua contribuição específica num fórum de discussão que é plural e a refletir sobre as relações entre bioética e teologia. Vários autores de tradição agnóstica começam a defender a importância das religiões para o debate ético e para a superação da crise ética da cultura atual pós-moderna. Essa cultura não tem condições de enfrentar as ameaças das manipulações genéticas. Questiona-se a secularização dominante que se instalou na modernidade.

    2016-02-01

    Full Text Available RESUMO Laser in situ Keratomileusis (LASIK é uma das técnicas mais aceitas na cirurgia refrativa atualmente. Sua previsibilidade, reprodutibilidade, segurança e baixos índices de efeitos colaterais justificam a ampla difusão dessa técnica. Trata-se de um procedimento cirúrgico a laser cujo objetivo consiste na modificação da estrutura corneana, permitindo uma mudança do ponto focal do olho. Dessa forma, é possível corrigir ametropias tais como a miopia, astigmatismo e pequenos graus de hipermetropia. A técnica do LASIK consiste na criação de um flap corneano por meio da utilização de um microcerátomo ou do laser de femtossegundo. Em seguida, é realizada a aplicação do excimer laser sobre o leito estromal com posterior reposicionamento do flap, criando-se uma interface entre as lamelas anterior e posterior da córnea. Apesar das inúmeras vantagens, existem patologias que resultam de complicações primárias da interface do flap, que podem causar confusão no momento do diagnóstico, por possuírem semelhanças quanto à sua apresentação clínica. O objetivo desse trabalho é definir, caracterizar e comparar tais entidades com intuito de facilitar o diagnóstico diferencial dessas patologias evitando a adoção de um tratamento equivocado. Como resultado do estudo, são apresentadas recomendações quanto à conduta nos casos de cada patologia de interface, com investigação por meio da anamnese e exame clínico, a fim de permitir diagnóstico diferencial entre as principais entidades primárias da interface do procedimento LASIK.

    MC Bernardes

    2012-08-01

    Full Text Available The Brazilian coastal zone extends from 4º N to 34º S latitude and because of its long extension, the interface zone from continent to ocean includes a high diversity of geomorphologic and oceanographic characteristics. The rivers from the Northeast and East regions are marked by a typical unimodal seasonal flux patterns but with different amplitudes. As the climate indicates, the rivers from the Northeast are subject to an accentuated seasonal variability with an elevated input and flood pulses during the rainy season and low to negligible fluxes during the dry season. Small-scale rivers usually present typical torrential behaviour. In the humid eastern region, the unimodal seasonal cycle is dampened with a more constant input supply. Recently, some studies have shown that the material supply from rivers along the Northeast and Eastern coasts is diluted by surface tropical waters of oceanic currents and that the estuarine plume dispersal is restricted to a narrow coastal belt. However, human impacts of course mask or even override both natural hydrological cycles and CO2 emissions from terrestrial biomes, or depending on the nature of the human impact, can even increase extreme events. Henceforth this contribution addresses the typological, hydrological and biome diversity of the four estuarine systems fed and affected by the respective Amazon, São Francisco, Paraíba do Sul and Plata watersheds.A zona costeira brasileira se estende de 4º N a 34º S de latitude. Por causa de sua longa faixa de zona de interface do continente com o oceano, é encontrada uma grande diversidade nas características geomorfológicas e oceanográficas. Os rios das regiões nordeste e leste mostram um padrão de fluxo sazonal normalmente unimodal, mas diferentes em amplitude. Conforme o clima indica, os rios do nordeste estão sujeitos a uma acentuada variabilidade sazonal, com elevação da vazão em forma de pulsos de inundação durante a estação chuvosa e

  12. The neuroanatomic complexity of the CRF and DA systems and their interface: What we still don't know.

    2018-07-01

    Corticotropin-releasing factor (CRF) is a neuropeptide that mediates the stress response. Long known to contribute to regulation of the adrenal stress response initiated in the hypothalamic-pituitary axis (HPA), a complex pattern of extrahypothalamic CRF expression is also described in rodents and primates. Cross-talk between the CRF and midbrain dopamine (DA) systems links the stress response to DA regulation. Classically CRF + cells in the extended amygdala and paraventricular nucleus (PVN) are considered the main source of this input, principally targeting the ventral tegmental area (VTA). However, the anatomic complexity of both the DA and CRF system has been increasingly elaborated in the last decade. The DA neurons are now recognized as having diverse molecular, connectional and physiologic properties, predicted by their anatomic location. At the same time, the broad distribution of CRF cells in the brain has been increasingly delineated using different species and techniques. Here, we review updated information on both CRF localization and newer conceptualizations of the DA system to reconsider the CRF-DA interface. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Full Text Available I have investigated, through the lens of the Complexity Paradigm, aligned with the premises of the Theory of General Systems and the concept of affordances, two virtual learning environments (VLEs, defining them as systems composed of digital genres, regarding a VLE as a complex adaptive system. These VLEs were reconfigured from the platforms TelEduc and Moodle and used to teach the discipline "Digital Literacy", in the course of Languages and Literature Teaching degree at the Federal University of Minas Gerais (UFMG, during the second semester of 2007 and the second semester of 2008, respectively. The analyses have indicated that the textual production of the emerging online discourse communities was influenced by the coupling of different layers of the interface, the textual genres and the communicative and pedagogical purposes and, also, by the affordances which were perceived and acted upon by teachers and learners. The analyzed VLEs have portrayed the characteristic of equifinality, regardless of the possibilities and constraints offered by the platforms TelEduc and Moodle.Investigo, através da lente do Paradigma da Complexidade, juntamente com os pressupostos da Teoria Geral dos Sistemas e do conceito de affordances, dois ambientes virtuais de aprendizagem (AVAs, definindo-os como sistemas compostos por gêneros digitais, partindo do pressuposto de que um AVA é um sistema adaptativo complexo. Esses AVAs foram reconfigurados a partir das plataformas TelEduc e Moodle e utilizados para ministrar a disciplina "Letramento Digital", no curso de Letras da Universidade Federal de Minas Gerais (UFMG, nos semestres 2007-2 e 2008-2, respectivamente. As análises indicam que a produção textual das comunidades discursivas on-line emergentes nos AVAs foi influenciada pelo acoplamento aninhado de camadas distintas da interface, dos gêneros textuais e dos propósitos comunicativos e pedagógicos, e, ainda, pelas affordances percebidas e efetivadas

    Full Text Available Este trabalho objetiva, primeiramente, evidenciar a utilidade da CFG e da FCFG no estudo da sintaxe formal. A aplicação de parsers baseados nesses formalismos na análise de um corpus pode revelar consequências de uma dada análise que de outro modo passariam despercebidas. O NLTK é uma caixa de ferramentas para o PLN em Python que possibilita a construção de parsers em diferentes arquiteturas. No entanto, para uma utilização não trivial dessa biblioteca na análise sintática automática são necessários conhecimentos de programação. Para permitir o acesso de não programadores à implementação e testagem de parsers, desenvolvemos o Donatus, uma interface gráfica amigável para as facilidades de parsing do NLTK, dotada de recursos adicionais que a tornam interessante também para programadores. Como exemplo do funcionamento da ferramenta e demonstração da sua relevância na investigação sintática formal, comparamos implementações de duas análises alternativas da modificação adjetival em português. A primeira abordagem, baseada na Teoria X-barra tradicional, produziu um grande número de pseudoambiguidades. Esse problema foi evitado por um parser baseado em abordagem no âmbito do Programa Minimalista. Sem o recurso do computador, essa diferença entre as duas abordagens não seria facilmente revelada.

    Full Text Available O estudo objetivou avaliar a resposta da assembleia de formigas que nidificam na interface solo-serapilheira a um gradiente de alteração ambiental. O estudo foi realizado em três ambientes com diferentes usos do solo: fragmento florestal, sistema agroflorestal (SAF e pastagem situados em região de domínio da mata atlântica no sudeste do Brasil. Em cada ambiente foram demarcadas 10 parcelas de 1 m² e todos os ninhos de formigas encontrados foram registrados. Foram encontrados 215 ninhos (103 no fragmento florestal, 64 no sistema agroflorestal e 48 na pastagem, de 31 espécies. O número acumulado de espécies foi maior no fragmento florestal que na pastagem, mas não diferiu do SAF. A composição de espécies foi diferente entre o fragmento florestal e os outros dois ambientes. A riqueza média de espécies de formigas por parcela foi maior no fragmento florestal e menor na pastagem. A quantidade de serapilheira não foi um fator importante para as diferenças na riqueza de espécies. Atividades humanas que reduzam a heterogeneidade da vegetação alteram a composição e diminuem a riqueza de espécies das assembleias de formigas.

    Full Text Available Objetivo: analisar a interface entre a natação e o tratamento da asma sob a perspectiva do praticante asmático. Método: trata-se de pesquisa qualitativa, realizada com cinco crianças e adolescentes, praticantes de natação. Foi utilizada como técnica de construção das informações empíricas a entrevista semiestruturada e, para análise das informações, a análise de conteúdo do tipo análise temática, em que emergiram dois núcleos de sentido: descoberta e percepção da doença e relação entre o tratamento da asma e a natação. Resultados: o reconhecimento do exercício físico como possível agravo da asma existe há décadas, todavia, há igual período de tempo se reconhece que o exercício físico regular e planejado torna-se um fator redutivo da frequência das crises asmáticas. O tratamento da asma para os sujeitos vem como algo substancial e, quando atrelado à prática esportiva, mais especificamente a natação, torna-se um eficiente manejo na trajetória fisiopatológica. Considerações finais: a asma tem sido um fator importante para adesão e manutenção na natação e que, de acordo com os participantes, a sua prática tem melhorado em diversos aspectos os sintomas da doença.

    Full Text Available Nas últimas décadas, assistimos à revitalização do debate em torno da agricultura familiar pela incorporação das discussões sobre as múltiplas funções da agricultura num rural que não pode mais ser visto como domínio exclusivo da atividade agrícola e dos agricultores. No contexto brasileiro, acreditamos que essa discussão deva ser permeada pela análise de como processos diferenciados de distribuição fundiária e desenvolvimento econômico e o tipo de agricultura resultante geram ruralidades específicas com características como, no caso da agricultura familiar, a manutenção de práticas sociais e de trabalho marcadas pelas relações de parentesco e vizinhança presentes numa sociedade de interconhecimento. Partindo desse princípio, este trabalho analisa a agricultura familiar de um bairro rural do município de Ouro Fino - MG, sua herança histórica e sua participação na criação de uma paisagem natural e humana que muito contribui para a atratividade da região.The last decades witnessed the revitalization of the debate around family farming with the addition of discussions regarding the multiple functions of agriculture, given the fact that rural areas are longer devoted exclusively to agricultural activities. In the Brazilian context, we believed that this debate must be permeated by analyses of how differentiated processes of land distribution and economic development, and the resulting types of agriculture, generate specific ruralities with characteristics such as, in the case of family farming, the maintenance of social and work practices marked by the relations among relatives and neighbours. It is in this light that this research analyses family agriculture in a rural area of Ouro Fino-MG, its historical heritage, and its participation in the creation of a physical and human landscape that greatly contributes to the attractiveness of the region.

No Brasil, somente em 2003 após publicação do Decreto 4.901, começou o desenvolvimento de pesquisas visando a construção do Sistema Brasileiro de Televisão Digital (SBTVD que dentre outros objetivos deveria promover a inclusão social e a formação de uma rede de educação a distância. A TV digital é considera por alguns autores como uma nova mídia, pois ela traz características do computador e da televisão. Desta forma esta nova mídia pode facultar novas formas de comunicação, de produção de conteúdos e de interatividade, o que para a área da educação são aspectos de fundamental importância, uma vez que até o momento com a televisão analógica não há possibilidades de construção de conteúdos colaborativos tanto pelo fator tecnológico quanto principalmente pelo fator político centralizador das produções disponíveis hoje. Nesse texto analisamos alguns aspectos da implantação da TV digital em Portugal e no Brasil bem como as possibilidades de utilização do Serviço de Apoio ao Professor em Sala de Aula (SAPSA desenvolvido pela Fundação Centro de Pesquisa e Desenvolvimento em Telecomunicações (CPqD. Como resultado deste trabalho, constatamos a potencialidade da TV digital na formação de redes de colaboração necessárias para o desenvolvimento da educação. Neste sentido, percebemos que cabe igualmente aos responsáveis pelos sistemas de educação e a nós educadores evidenciarmos que queremos uma TV digital que possibilite a construção de redes colaborativas capazes de potencializar a interconexão entre educação, culturas e conhecimentos.AbstractAt the end of the 80’s, some European countries as well as Japan and the United States started researches for the development of digital tv models.

    Many operations and procedures in the petroleum industry are related to the immiscible displacement of a fluid by another one, as the secondary recovery of petroleum and pumping operation through pipelines of high viscosity oils. In this context, an stability analysis of the water-oil interface as well as of the factors that leads to the appearance of the viscous fingering phenomenon, represented by the viscous flowing of one phase that penetrates inside of the other one in the form of one or more fingers, is of major importance for the forecast, simulation and control of operations involving this kind of system. From the theories of perturbation and unstable immiscible displacement of fluids, initially conceived for cells of parallel slabs (Hele-Shaw), the authors intend to extend the concepts and adapt the criteria for the three-dimensional geometry in macroscopic scale.

O objetivo principal de um sistema VGI é permitir que um voluntário colete dados geográficos; para isso é essencial considerar, durante o processo de desenvolvimento da aplicação, a interação do usuário com os elementos da interface. Sistemas VGI como o OpenStreetMap têm diferentes processos de interação com o usuário, os quais implicam em diferentes tipos de interfaces, funcionalidades e formulários. A execução de uma tarefa, assim como o seu resultado, pode diferir dependendo do sistema utilizado. Diferentes processos de interação acarretam em diferentes experiências do usuário, e consequentemente afetam a qualidade e a confiabilidade da informação espacial coletada. O processo de interação pode também influenciar a retenção de usuários no sistema, bem como a adesão de novos voluntários. O objetivo desta pesquisa é obter um panorama de aspectos da usabilidade de sistemas VGI, especificamente na tarefa de inserção de feições geográficas, desde o acesso ao sistema até o sucesso ou falha na execução da tarefa. Para execução desta pesquisa foram realizados testes com usuários com diferentes tipos de familiaridade com os sistemas Wikimapia, OpenStreetMap, e Wikiloc, com o objetivo final de inserir uma ou mais feições geográficas nesses aplicativos

    Full Text Available Silicon nitride is a covalent ceramic material of high corrosion resistance and mechanical stability at elevated temperatures. Due to these properties, its use in metallurgical processes, such as the casting of alloys, is increasing. Therefore, the characterization of the interface between Si3N4 and the casted metal is of great importance to investigate possible interactions, which might deteriorate the ceramic mould or contaminate the metal. In this work, the use of Si3N4 as crucible material for Al-casting has been studied, by investigating the corrosion attack of liquid Al at a temperature of 1150 ºC during 30 days in air. The interface was characterized by X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy. It has been found that due to superficial oxidation two oxide layers form - SiO2 on Si3N4 and Al2O3 on Al - which effectively hinder further reactions under the conditions studied, confering high corrosion resistance to the Si3N4 crucible.Nitreto de silício (Si3N4 é um material cerâmico covalente de elevada resistência à corrosão e estabilidade mecânica em temperaturas elevadas. Devido a essas propriedades, sua utilização em processos metalúrgicos, tais como em fundição de ligas metálicas, é crescente. Desta forma, a caracterização da interface entre Si3N4 e metais fundidos é de grande interesse para investigar possíveis interações as quais poderão deteriorar o material cerâmico e/ou contaminar o metal. Nesse trabalho o uso de Si3N4 como material base de cadinhos para fundição de alumínio foi estudado, pela investigação do ataque corrosivo de Al líquido a 1150 ºC durante 30 dias, ao ar. A interface foi caracterizada por difração de raios X, microscopia eletrônica de varredura e espectroscopia de energia dispersiva. É encontrado que devido à oxidação superficial dois óxidos se formam - SiO2 no Si3N4 e Al2O3 no Al - os quais evitam possíveis reações sob as condi

Each group received a different type of treatment: Group PSP: Polished with sandpaper 600; Group PCP: Polished with sandpaper 600 and application of the metal primer Alloy Primer (Kuraray; Group JSP: Sandblasted with 100µm aluminum oxide; Group JCP: Sandblasted with 100mm aluminum oxide and treated with a metal Primer. The groups were cemented and stored in distilled water at 37ºC for 36 hours and submitted to the shear bond strength test. The mean and standard deviation (in Kgf/cm² obtained for each group was: PSP 4.0/0.4; PCP 88.9/33.6; JSP 163.2/27.6; JCP 144.5/54.0. After the statistical analysis the authors concluded that: the highest values were obtained for the sandblasted groups (JSP, JCP, regardless of the primer application; the Alloy Primer increased the retention between the Rely X cement and the polished surface of the Co-Cr-Mo alloy, yet its bond strength was not greater than that obtained with sandblasting; all specimens showed adhesive failures in the tested interface.Para avaliar o efeito de diferentes tratamentos superficiais sobre a resistência ao cisalhamento da união entre uma liga metálica (Co-Cr-Mo - Remanium CD e um cimento resinoso (Rely X TM e analisar o tipo de fratura durante a separação dos espécimes, quarenta pares de discos metálicos foram fundidos, regularizados e polidos, submetidos a quatro ciclos térmicos (vácuo, 960ºC, 8 minutos e divididos aleatoriamente em quatro grupos.

    Directory of Open Access Journals (Sweden)

    Daniel Gustavo Brusius Wilbert

    Full Text Available Resumo Os agregados provenientes da reciclagem de concreto geralmente possuem propriedades inferiores às dos agregados naturais, o que limita suas alternativas de reciclagem. Entretanto, muitos estudos vêm demonstrando seu potencial de utilização na confecção de concretos, a partir de avaliações de propriedades mecânicas e microestruturais, e de melhorias na forma de mistura dos agregados. O presente trabalho analisa a viabilidade de utilização da técnica de nanoindentação para a avaliação da interface que se forma entre a pasta e o agregado reciclado em concretos com esse tipo de agregado. Foram produzidos corpos de prova que representam a região de interface em concretos em que os agregados reciclados foram adicionados à mistura no estado seco, método que vem sendo utilizado com o intuito de melhorar a zona de transição em função da absorção do excesso de água da pasta e de partículas de aglomerante pelos poros vazios do agregado reciclado. Os corpos de prova de referência foram comparados com outros em que foi realizada a adição de fíler basáltico e de cinza de casca de arroz. A técnica de nanoindentação possibilitou verificar que a utilização de agregado no estado seco gera zonas de transição de elevada qualidade e que a adição de cinza de casca de arroz aumenta a dureza da região de interface.

Nosso intuito geral é o de contribuir para o debate referente à reflexão sobre o papel dessas políticas no desenvolvimento dos sistemas de educação superior na região. Especificamente, nos propomos a levantar, comparando com a realidade brasileira, alguns pontos relevantes da Colômbia em relação às múltiplas complexidades nas quais estão inscritos, na atualidade, os temas da acreditação e da avaliação. De modo geral, segundo os estudos parcialmente construídos aqui, os mecanismos de acreditação e avaliação estão na lista de prioridades da agenda governamental e acadêmica tanto na Colômbia quanto no Brasil. Nesse quadro, eles representam o esforço de cooperação internacional na região, porém com dupla finalidade e não isento de contradições: de um lado, para defender os interesses nacionais, dando ênfase na educação superior como bem público sujeito às ações e estratégias do Estado e não do mercado e, de outro, para ampliar a mobilidade estudantil e docente num quadro crescente de mudanças sociais, econômicas e culturais, garantindo e assegurando a qualidade da formação educacional e científica das pessoas.We present in this article some characteristics of accreditation and evaluation policies for higher education in Colombia and their interfaces with Brazil. Our overall aim is to contribute to the debate on the role of policies in the development of higher education systems in the region.

A História da Saúde passou igualmente por esta mudança. O objetivo deste artigo é apresentar, de forma sumária, alguns elementos presentes no debate historiográfico contemporâneo sobre História da Saúde, da Ciência, das Mulheres e das Profissões. A escolha destas áreas se justifica na medida em que elas são interfaces potenciais para a escrita da História da Enfermagem. Cada uma delas, da sua maneira, contribui para valorizar esta profissão, pois resgata sua memória e divulga sua história: partes imprescindíveis para a construção da identidade de qualquer profissão. Com isso, pretendemos sugerir que a produção histórica em Enfermagem leve em consideração esta controvérsia historiográfica e se inscreva nela de forma consciente e qualificada.Durante el siglo XX, el conocimiento histórico terminó por presentarse en forma de simples hechos con sus correspondientes fechas.

Busca, assim, indicar como uma sociedade viabiliza a materialização de novos padrões de racionalidade, de modo que estes passem a interferir nas concepções de realidade de seus sujeitos. O estudo apresenta um modelo de análise sistêmico da responsabilidade social corporativa, integrando os conceitos da lógica do desenvolvimento social, proposta por Jürgen Habermas, e os processos de isomorfismo observados nas organizações e oriundos da teoria institucional. Com o intuito de fornecer um modelo de análise teórico-empírica do tema, as iniciativas socioambientais são justificadas, inicialmente, pelo seu papel como fator de diferenciação ou como estabelecedor da reputação da organização e de seus produtos e serviços. Na sequência, observa-se um processo de normatização, quando é definido um novo padrão mínimo de atuação das organizações e, porque não dizer, de maturidade social, reiniciando nesse ponto uma nova busca de diferenciais competitivos e avanços sociais. Esse enfoque de investigação da atuação das empresas na arena socioambiental rompe com a perspectiva ingênua e voluntarista de que a emergência dessas iniciativas ocorra conforme diferentes níveis de conscientização do meio empresarial.

    Full Text Available Este artigo propõe a construção de uma interface entre história e ensino de matemática a partir de um diálogo entre historiadores e educadores da matemática. Para tanto, consideramos aspectos epistemológicos e metodológicos ligados à história da matemática, pautada em tendências historiográficas atuais, juntamente com a metodologia baseada no movimento lógico-histórico. A interface contemplou o movimento do pensamento na formação dos conceitos e o contexto no qual tais conceitos foram desenvolvidos, de modo a conduzir à reflexão sobre o processo histórico da construção do conhecimento para a elaboração de atividade didática. Esta atividade teve por base um documento do século XVI dedicado à construção e uso de "instrumentos matemáticos", e sua elaboração levou em consideração uma intencionalidade e um plano de ação que viabilizaram o seu desenvolvimento. A organização do ensino articulou as conexões internas e externas trazidas pela análise do documento e a forma do pensamento do desenvolvimento do conceito.This paper proposes to devise an interface between history and mathematics education based on a dialogue between historians of mathematics and educators. Regarding this, we have considered epistemological and methodological aspects of the history of mathematics based on current trends in historiography along with the methodology based on the logic-historical approach. The interface sought to envisage the movement in thought in the context in which these very concepts were conceived and the context in which mathematical concepts were developed. This interface led us to reflect on the historical process of development of knowledge by which a didactic activity could be devised. This activity was based on a sixteenth century document devoted to the construction and use of "mathematical instruments". Activity elaboration took into account an intention and a plan of action through which its application was

    Full Text Available OBJETIVO: Investigar a percepção dos médicos sobre a experiência de atenderem ambulatorialmente crianças com doença ocular grave e como compreendem sua interferência na relação mãe-filho. MÉTODOS: Foram realizadas entrevistas semiestruturadas com os oftalmologistas (setores de retina, glaucoma, segmento anterior e oftalmopediatria e observação das consultas ambulatoriais durante três meses. RESULTADOS: Idealização da figura do médico e da mãe; dificuldades na hora de transmitir o diagnóstico; e reconhecimento de que o profissional interfere na relação da dupla durante seus encontros. CONCLUSÃO: O desafio do médico está em dar as informações sobre diagnóstico e tratamento; ter disponibilidade para escutar, esclarecer e orientar e nos casos graves mostrar que a criança tem outras potencialidades além da visão.

  13. Autogestão e subjetividade: interfaces e desafios na visão de especialistas da ANTEAG, UNISOL e UNITRABALHO

    Directory of Open Access Journals (Sweden)

    Fernanda Mitsue Soares Onuma

    Full Text Available A Administração, em sua corrente teórica dominante, tem se prestado a transformar as empresas em espaços de propagação ideológica acerca de formas hierarquizadas de organização e gestão do trabalho. Negando esta dimensão política e ideológica da ação administrativa, a Teoria da Administração tem se tornado cúmplice dos interesses do business, educando profissionais cujas ações acabam sobrepondo o econômico ao fator humano e às questões éticas. Em contraposição a este cenário de injustiça e exploração, encontra-se a autogestão, forma de gestão não hierarquizada e democrática cuja implantação tem enfrentado muita dificuldade. Para buscar compreender os desafios que se impõem aos trabalhadores e trabalhadoras que se propõem a trabalhar de maneira autogestionária, foram realizadas entrevistas semi-estruturadas com um especialista em cada uma das três seguintes entidades de fomento a organizações autogestionárias: ANTEAG, UNISOL e UNITRABALHO. Os dados foram analisados por meio do método de análise de conteúdo e indicaram que a autogestão, na visão destes profissionais, implica necessidade de uma mudança de subjetividade desses trabalhadores e trabalhadoras, acostumados ao modelo de trabalho hierarquizado e não democrático. Com base nisso, argumenta-se que, para uma melhor compreensão da dificuldade de implantação da autogestão nas organizações, é necessária a adoção de um conceito de subjetividade que englobe não só o seu caráter individual, mas também seu caráter coletivo. Conquanto a visão da subjetividade individual e coletiva nos leve a refletir sobre o fato de que os desafios da prática da autogestão são mais profundos do que aparentam inicialmente, acreditamos que sua resolução pode estar mais próxima de nós do que imaginamos.

    Full Text Available Resumo: Refletindo acerca da Educação e História na perspectiva analítica de Gênero, este trabalho visa problematizar as relações entre Educação e Gênero, pautando –se em um olhar dialógico e equitativo da Educação. A fim de entendermos as relações de poder intrínsecas à construção histórica, notamos silenciamentos das mulheres nos Livros de História do Ensino Básico, vistas como notas de rodapé e anexos. Assim, presumindo que há uma ausência da história das mulheres na historiografia do livro didático de história, este trabalho se propõe a discutir não apenas as invisibilizações das mulheres nos livros de História, mas também, refletir acerca da Educação e Gênero, debatendo a representatividade das mulheres no livro didático e a historicização  das relações de gênero, a fim de um construto historiográfico igualitário, entendendo o papel da educação, frente aos  desafios na quebra de paradigmas excludentes.   Palavras-Chave: Educação, Gênero, Livro didático de História.

Métodos: a abordagem metodológica utilizada foi a qualitativa, e o instrumento para a coleta de dados foi entrevista semiestruturada com sete professores em Blumenau - SC. A análise dos dados foi realizada por meio da Análise de Conteúdo. Resultados: não há uma preocupação em relação à duração da aula para alunos hispano falantes. O nível de fluência está associado ao nível de conhecimento prévio da língua. Os professores buscam submeter seus alunos ao contexto de imersão do uso do português. Apesar de utilizarem estratégias para minimizarem as dificuldades no ensino de expressões idiomáticas, pronúncia, entonação, acentuação, escrita e conjugação de verbos, elas ainda não foram solucionadas. Conclusão: considerou-se que o fonoaudiólogo pode contribuir com a atuação dos professores de português, na modalidade de língua estrangeira, com orientações que envolvem habilidades auditivas e pronúncia, entre outras questões mais específicas de comunicação, pertinentes à Fonoaudiologia, em especial à Fonoaudiologia Educacional, bem como na elaboração de novos materiais didáticos.

Os objetos de pesquisa selecionados foram o Plano de Bacia Hidrográfica Tietê-Jacaré e os Planos Diretores de Araraquara e São Carlos. A pesquisa abordou as seguintes categorias de análise: unidades de planejamento, instrumentos ambientais contidos no Plano de Bacia e nos Planos Diretores, instâncias de gestão e grau de influência entre os planos analisados. O método se pautou em levantamentos, análises bibliográficas e documentais, entrevistas semiestruturadas e questionários. Os resultados obtidos apontaram que o Plano de Bacia Hidrográfica ainda apresenta lacunas e dificuldades para uma atuação mais ampliada. Não reconhece os conflitos de uso da terra e de organização territorial como uma vulnerabilidade que precisa ser enfrentada. Mostraram, ainda, que os Planos Diretores Municipais concentram-se na aplicação dos instrumentos voltados ao parcelamento e ao zoneamento urbano. Nesses planos, as condições e os aspectos ambientais e regionais se apresentam como uma temática periférica e pouco articulada com as demais políticas. As análises procuraram demonstrar a complexa relação entre políticas, instrumentos e instâncias de planejamento e gestão, explicitando os obstáculos que dificultam a aplicação do conceito de gestão territorial integrada.

Interessamo-nos pela relação entre referências normativas do trabalho intelectual de pesquisadores e jornalistas e suas investigações como uma decorrência da interface entre fatores internos e externos que moldam a organização e produção de saberes configurando novas formas de construção de conhecimento (ciência, cultura, informações. No caso do jornalismo concordamos que este pode ser compreendido como um conhecimento que se origina das chamadas “mesoepistemologias” enquanto maneiras de conhecer que surgem na interface entre polos científico e grande público. Trata-se da concepção de saberes ancorada em uma cientificidade própria. Embora reconheçamos que há tanto na atividade científica como na jornalística a participação da objetividade, imparcialidade e neutralidade como valores positivistas que norteiam a produção de conteúdos cognitivos nesses ambientes normativos os quais devem ser problematizados em função de operações subjetivas e intencionais que se manifestam entre cientistas e jornalistas enquanto produtores culturais e do envolvimento de epistemologias populares como coprodutoras desses conteúdos. O problema da definição do lócus onde a ciência é concebida, justificada e legitimada é tema caro para sociologia do conhecimento que tem apresentado abordagens distintas para lidar com a questão dos elementos internos e externos ou de sua interseção, o social e o científico, na definição desse lugar.

In this article, we focus our attention on interfacial superconductivity, a field that has been boosted by the discovery of superconductivity at the interface between the two band insulators LaAlO{sub 3} and SrTiO{sub 3}. We explore the properties of this amazing system that allows the electric field control and on/off switching of superconductivity. We discuss the similarities and differences between bulk doped SrTiO{sub 3} and the interface system and the possible role of the interfacially induced Rashba type spin–orbit. We also, more briefly, discuss interface superconductivity in cuprates, in electrical double layer transistor field effect experiments, and the recent observation of a high T{sub c} in a monolayer of FeSe deposited on SrTiO{sub 3}.

    Strzalkowski, Ireneusz

    1997-01-01

    This book presents an extended form of the 1994 Dirac Memorial Lecture delivered by Pierre Gilles de Gennes at Cambridge University. The main task of the presentation is to show the beauty and richness of structural forms and phenomena which are observed at soft interfaces between two media. They are much more complex than forms and phenomena existing in each phase separately. Problems are discussed including both traditional, classical techniques, such as the contact angle in static and dynamic partial wetting, as well as the latest research methodology, like 'environmental' scanning electron microscopes. The book is not a systematic lecture on phenomena but it can be considered as a compact set of essays on topics which particularly fascinate the author. The continuum theory widely used in the book is based on a deep molecular approach. The author is particularly interested in a broad-minded rheology of liquid systems at interfaces with specific emphasis on polymer melts. To study this, the author has developed a special methodology called anemometry near walls. The second main topic presented in the book is the problem of adhesion. Molecular processes, energy transformations and electrostatic interaction are included in an interesting discussion of the many aspects of the principles of adhesion. The third topic concerns welding between two polymer surfaces, such as A/A and A/B interfaces. Of great worth is the presentation of various unsolved, open problems. The kind of topics and brevity of description indicate that this book is intended for a well prepared reader. However, for any reader it will present an interesting picture of how many mysterious processes are acting in the surrounding world and how these phenomena are perceived by a Nobel Laureate, who won that prize mainly for his investigations in this field.

    Directory of Open Access Journals (Sweden)

    Renata Castelo Peixoto

    Full Text Available O artigo propõe uma reflexão psicolingüística sobre as construções conceituais de crianças surdas no que diz respeito à escrita. O trabalho revela, a partir de um diálogo com as idéias de Emília Ferreiro e Ana Teberosky, que a psicogênese da escrita vivenciada por crianças surdas, que têm a língua de sinais como primeira língua e língua de instrução, se desenrola de forma diferente ao que é vivido por crianças ouvintes em processo inicial de construção da escrita. As principais especificidades dessa aquisição relacionam-se: a não-fonetização da escrita, a uma intensa exploração dos aspectos viso-espaciais da escrita e ao uso dos parâmetros fonológicos da língua de sinais como elemento regulador e organizador da escrita. Tais peculiaridades exigem, portanto, que a escola e o professor alfabetizador revejam suas concepções sobre o processo de escrita no surdo, pensando em (novas práticas pedagógicas que considerem a realidade bilíngüe e sua relação não-sonora com a escrita.

    Full Text Available Este trabalho busca trazer para o campo da Saúde Coletiva as contribuições da ecologia política e da economia ecológica, visando a integrar as discussões em torno da promoção da saúde, da sustentabilidade sócio-ambiental e dos processos de desenvolvimento. A economia ecológica é um campo de estudos transdisciplinar recente que reúne economistas com outros profissionais das ciências sociais, humanas e biológicas. Ela tem desenvolvido novos conceitos e metodologias que buscam captar a relação entre a economia com os processos ecológicos e sociais, como metabolismo social e perfil metabólico, inter-relacionando os fluxos econômicos com os de materiais e energia, e produzindo indicadores e índices de (insustentabilidade. A ecologia política, por sua vez, aborda as questões ecológicas e os conflitos sócio-ambientais a partir de dinâmicas econômicas e de poder que caracterizam as sociedades modernas. A Saúde Coletiva e as discussões sobre a promoção da saúde podem ampliar sua compreensão sobre o território, as comunidades, o papel da ciência e das instituições a partir das contribuições da ecologia política e da economia ecológica no entendimento dos modelos de desenvolvimento e os conflitos distributivos e sócio-ambientais por ele gerados.This article proposes to focus contributions from political ecology and ecological economics to the field of collective health with a view towards integrating the discussions around health promotion, socio-environmental sustainability, and development.

O Relatório 2000 trouxe à agenda da OMS o comprometimento com os objetivos louváveis de avaliação dos sistemas de saúde, monitoramento das desigualdades em saúde e alcance da equidade no financiamento da saúde. Entretanto, o instrumental utilizado foi exposto a inúmeras críticas, tanto de cunho metodológico como conceitual. Como parte deste processo, para suprir informações sobre o estado de saúde das populações, a OMS propôs a elaboração da Pesquisa Mundial de Saúde (PMS em vários países membros. No Brasil, a PMS foi conduzida no ano de 2003, e objetivou estabelecer parâmetros consistentes para avaliar o estado de saúde da população e a assistência prestada de acordo com as expectativas da população usuária, além de mensurar as desigualdades socioeconômicas em saúde. O inquérito foi realizado em 5000 indivíduos com 18 anos e mais de idade, em âmbito nacional. A amostragem foi realizada em três estágios. No primeiro, foram selecionados 250 setores censitários, com probabilidade proporcional ao tamanho. Em cada setor, foram selecionados 20 domicílios, por amostragem inversa.

    Full Text Available The classical (boolean notion of refinement for behavioral interfaces of system components is the alternating refinement preorder. In this paper, we define a distance for interfaces, called interface simulation distance. It makes the alternating refinement preorder quantitative by, intuitively, tolerating errors (while counting them in the alternating simulation game. We show that the interface simulation distance satisfies the triangle inequality, that the distance between two interfaces does not increase under parallel composition with a third interface, and that the distance between two interfaces can be bounded from above and below by distances between abstractions of the two interfaces. We illustrate the framework, and the properties of the distances under composition of interfaces, with two case studies.

  7. Percolation Model of Adhesion at Polymer Interfaces

    Science.gov (United States)

    Wool, Richard P.

    1998-03-01

    Adhesion at polymer interfaces is treated as a percolation problem, where an areal density of chains Σ, of length L, contribute a number of entanglements to the interface of thickness X. The fracture energy G, is determined by the fraction of entanglements P, fractured or disentangled in the deformation zone preceding the crack tip, via G ~ P-P_c, where Pc is the percolation threshold, given by Pc = 1- M_e/Mc . For incompatible A/B interfaces reinforced with Σ diblocks or random A-B copolymers of effective length L'(L' ~ 0 for brushes and strongly adsorbed chains), we obtain P ~ ΣL/X, Pc ~ Σ _cL/X, such that G = K(Σ - Σ _c)+ G_o, where K and Go ~ 1 J/m^2 are constants. Note that Log G vs Log Σ will have an apparent slope of about 2, incorrectly suggesting that G ~ Σ ^2. For cohesive fracture, disentanglement dominates at M M*, G = G*[1-M_c/M]. For fatigue crack propagation da/dN, at welding interfaces, we obtain da/dN ~ M-5/2(t/Tr)-5/4, where t is the welding time and Tr is the reptation time. For polymer-solid interfaces, G ~ (X/R)^2. where X is the conformational width of the first layer of chains of random coil size R. The fractal nature of the percolation process is relevant to the fracture mechanism and fractography.

Para tanto, o esforço foi direcionado ao resgate do que é comum aos fenômenos da gestão e do desenvolvimento - os substratos antropológico e ecológico -, nucleados nos princípios da reciprocidade dialógica, concretizadora da condição antropológica, e da finitude, caracterizadora da condição ecológica. Ao final, são apresentadas oito potenciais contribuições advindas da exploração renovada da interface entre a gestão e o desenvolvimento. Propôs-se, ainda, a substituição da lógica instrumental da eficiência financeira, comum à concepção tradicional dos fenômenos estudados, pela lógica da simbiose dialógica homem/natureza, uma vez que, como fenômenos sociais, desenvolvimento e gestão, mediados pelo meio, também são ecológicos em sua essência.

  16. Subcritical crack growth along polymer interfaces

    Science.gov (United States)

    Gurumurthy, Charavana Kumara

    2000-10-01

    The adhesion characteristics have been investigated for a polyimide (PI)/model epoxy (ME) interface that is important for microelectronic applications. The fracture toughness (G*c) of this interface has been measured using an asymmetric double cantilever beam (ADCB) technique. The G*c is low, 10-25 J/m 2, and is sensitive to the mechanical phase angle psi. A modified ADCB setup has been used to measure the subcritical crack growth velocity v due to the stress-assisted water attack (SAWA) at various relative humidities (RH) and temperatures (T) as a function of its driving force (the strain energy release rate) G*. The threshold G* decreases remarkably. Above the threshold log v rises linearly with √ G* (a hydrolysis controlled regime) but then enters a regime where the crack velocity is almost independent of √G*, i.e., v = v* (a transport controlled regime). A model for SAWA has been developed based on thermally-activated kinetics for hydrolysis of the ester covalent bonds that bridge from one side to the other of the interface. A new technique has been developed for the determination of the fatigue crack growth under thermal (T) and hydro-thermal (HT) conditions as a function of the range in the strain energy release rate (DeltaG). Under T-fatigue, the fatigue crack growth per unit temperature cycle (da/dN) increases as a power of DeltaG, i.e., a Paris law relationship holds. The HT da/dN measured is higher than da/dN under T-fatigue conditions and has been successfully modeled as a summation of two components: (a) the da/dN due to T-fatigue and (b) the da/dN due to the SAWA along the interface for a given T-cycle. A surface modification procedure that converts a thin interpenetrated by a solvent cast ME is used to strengthen ME/PI interface. The G* c increases with the interpenetration distance w. Increasing w also improves the resistance of the PI/ME interface to SAWA with the threshold G* increasing and the water transport controlled velocity (v

    At the interface of two two-dimensional quantum systems, there may exist interface currents similar to edge currents in quantum Hall systems. It is proved that these interface currents are macroscopically quantized by an integer that is given by the difference of the Chern numbers of the two systems. It is also argued that at the interface between two time-reversal invariant systems with half-integer spin, one of which is trivial and the other non-trivial, there are dissipationless spin-polarized interface currents.

    Pipelines are interconnected ducts systems used to transport large quantities of petroleum and its by-products, are more economical, eliminate the need for stocks and, in addition, present great safety in operation minimizing the possibility of loss or theft. In many cases, especially in the petrochemical industry, the same transport line is used to carry more than one type of product (poliduct), such as: gasoline, diesel and kerosene. In the operation of a poliduct there is a sequence of products to be transported and during the exchange of the product, there are still fractions of volume of the previous product thus occurring contaminations. The traditional solution is to discard all this volume; however it is important to identify precisely this region in order to reduce the costs of reprocessing and treatment of discarded products. This work presents a methodology to evaluate the sensitivity of the gamma densitometry technique in the precise identification of the interface region by optimizing the transportation of petroleum by - products into polyducts. The study considered geometry composed of a source of {sup 137}Cs, an acrylic tubing measuring 8.0 cm in diameter and a 1 x 1 “NaI (T1) detector, a position diametrically opposed to a radiation source to measure the transmitted beam. Using computational simulations using the Monte Carlo method with the MCNPX code, measurement geometry with the highest sensitivity for the calculation of volume fractions was proposed. The pertinent technical data (dimensions and materials) to perform the simulation of the detectors were based on information obtained from the gammagraphy technique. The study had a theoretical validation through analytical equations and the results show that it is possible to identify the interface region with an accuracy of 1%. (author)

    Juntunen, Janne; Merikoski, Juha

    2010-01-01

    Diffusion in an evolving environment is studied by continuous-time Monte Carlo simulations. Diffusion is modeled by continuous-time random walkers on a lattice, in a dynamic environment provided by bubbles between two one-dimensional interfaces driven symmetrically towards each other. For one-dimensional random walkers constrained by the interfaces, the bubble size distribution dominates diffusion. For two-dimensional random walkers, it is also controlled by the topography and dynamics of the interfaces. The results of the one-dimensional case are recovered in the limit where the interfaces are strongly driven. Even with simple hard-core repulsion between the interfaces and the particles, diffusion is found to depend strongly on the details of the dynamical rules of particles close to the interfaces.

  7. User interface support

    Lewis, Clayton; Wilde, Nick

    1989-01-01

    Space construction will require heavy investment in the development of a wide variety of user interfaces for the computer-based tools that will be involved at every stage of construction operations. Using today's technology, user interface development is very expensive for two reasons: (1) specialized and scarce programming skills are required to implement the necessary graphical representations and complex control regimes for high-quality interfaces; (2) iteration on prototypes is required to meet user and task requirements, since these are difficult to anticipate with current (and foreseeable) design knowledge. We are attacking this problem by building a user interface development tool based on extensions to the spreadsheet model of computation. The tool provides high-level support for graphical user interfaces and permits dynamic modification of interfaces, without requiring conventional programming concepts and skills.

    Full Text Available Configura-se esta pesquisa em um estudo de cunho qualitativo e caráter bibliográfico, a qual almeja examinar a interrelação entre a gestão dos processos de adaptação social e o princípio da responsabilidade. Entende-se que se adentra em temática ampla e complexa, que perpassa todas as esferas do espaço público, visto que o fomento ao meio ambiente ecologicamente equilibrado afeta a todos os indivíduos, global e indistintamente. Nesse plano, mesmo sendo esta uma problemática mundial e que, consequentemente, requer uma solução abrangente, mostra-se indispensável que sejam buscadas alternativas já em âmbito local, pois é assim que se vai galgando o esclarecimento e a conscientização de todos os sujeitos. Para que o objetivo primordial desta investigação fosse alcançado utilizaram-se as concepções, de modo precípuo, de Anthony Giddens, quando este trata, especificamente, do manejo das complexidades sociais e econômicas introduzidas pelas novas formas de tecnologia, bem como a interconexão dos riscos a serem assumidos com o princípio de responsabilidade proposto por Hans Jonas. Dada a complexidade destas temáticas, o que se percebe é uma apatia social, em que a indiferença se faz, paulatinamente, mais presente. No entanto, é essencial compreender que, para haver a desobstaculização das problemáticas ainda arraigadas, a fim de almejar uma sociedade mais igual e mais responsável pelo meio ambiente, mostra-se crucial uma reformulação na práxis política, social e cultural. É mediante o engajamento político e o ativismo dos grupos sociais que se pode propor mudanças estruturais.

    Full Text Available No presente trabalho duas técnicas de manufatura de compósitos termoplásticos estruturais são investigadas: a de moldagem por compressão a quente convencional e a de pré-impregnação via suspensão polimérica. A primeira consiste na impregnação do reforço via polímero fundido; enquanto que a segunda faz uso de suspensões poliméricas aquosas, onde a impregnação do reforço ocorre pelo contato deste com a suspensão aquosa de partículas da matriz polimérica. Esta técnica combina a matriz polimérica em pó com um outro polímero formador da suspensão, um poli(ácido âmico - PAA, sendo que os dois polímeros são simultaneamente depositados sobre o reforço, durante a impregnação. Este mesmo PAA, em uma segunda fase do processo, é convertido termicamente em uma poliimida (PI podendo formar uma região de interfase entre o reforço e a matriz polimérica. Este trabalho tem como objetivo a síntese e a caracterização de um PAA, à base de BTDA/DDS, e a avaliação de sua influência na formação da região de interfase em compósitos de poli(sulfeto de fenileno (PPS/fibras de carbono. Resultados de DSC e TG mostram o sucesso da síntese do PAA e de sua conversão em PI, esta com estabilidade térmica até 396 °C. O compósito processado pela técnica de suspensão polimérica apresenta resistência ao cisalhamento interlaminar (56,3 MPa 12,6% superior ao compósito obtido por moldagem por compressão a quente convencional (50,0 MPa.

    The aim of this study was to investigate the effects of low-intensity irradiation with GaAlAs laser (red emission) on the ultrastructure of dentine-pulp interface after conventionally prepared class I cavity preparation. Two patients with 8 premolars for extraction indicated for orthodontic reasons. Class I cavities were prepared in these teeth that were then divided into two groups. The first group received a treatment with laser with continuous emission, {lambda}=660 nm, with maximum power output of 30 mW. The dosimetry applied was of approximately 2J/cm{sup 2}, directly and perpendicularly into the cavity in only one section. After the irradiation, the cavities were filled with composite resin. The second group received the same treatment, except by the laser therapy. Twenty-eight days after the preparation, the teeth were extracted and were processed for transmission electron microscopy analysis. Two sound teeth, without any preparation, were also studied. The irradiated group presented odontoblastic processes in higher contact with the extracellular matrix and the collagen fibers appeared more aggregated and organized than those of control group. These results were also observed in the healthy-teeth. Thus, we suggest that laser irradiation accelerates the recovery of the dental structures involved in the cavity preparation at the pre-dentine level. (author)

    The development of simulation systems has been increasingly improved to ensure security and reliability to the systems being associated. Computational tools, simulation systems and programming languages increasingly allow the diversification of control systems. With increasing concern about monitoring the key parameters involved in chain reactions inside a nuclear reactor, new technologies are being developed to ensure operations safety. This paper deals with a practical application of a work that is being developed in the Center for the Development of Nuclear Technology - CDTN, which intends to simulate the operation of the TRIGA-IPR-R1 nuclear research reactor using the LabVIEW® software, evaluating the evolution of the neutron flux and other related events. In this paper, the visual interface of the reactor control table, developed through virtual instruments that allow, in a vast repertoire of tools, replicating the panels of the control table in modern screens that can be operated by a user of an analogous form, but still more practical and complete. Since the innovations developed for research reactors can be replicated in power reactors, and because of their lower operating and maintenance costs, projects in this area allow the development of several technologies.

  16. Solar wind stream interfaces

    International Nuclear Information System (INIS)

    Gosling, J.T.; Asbridge, J.R.; Bame, S.J.; Feldman, W.C.

    1978-01-01

    Measurements aboard Imp 6, 7, and 8 reveal that approximately one third of all high-speed solar wind streams observed at 1 AU contain a sharp boundary (of thickness less than approx.4 x 10 4 km) near their leading edge, called a stream interface, which separates plasma of distinctly different properties and origins. Identified as discontinuities across which the density drops abruptly, the proton temperature increases abruptly, and the speed rises, stream interfaces are remarkably similar in character from one stream to the next. A superposed epoch analysis of plasma data has been performed for 23 discontinuous stream interfaces observed during the interval March 1971 through August 1974. Among the results of this analysis are the following: (1) a stream interface separates what was originally thick (i.e., dense) slow gas from what was originally thin (i.e., rare) fast gas; (2) the interface is the site of a discontinuous shear in the solar wind flow in a frame of reference corotating with the sun; (3) stream interfaces occur at speeds less than 450 km s - 1 and close to or at the maximum of the pressure ridge at the leading edges of high-speed streams; (4) a discontinuous rise by approx.40% in electron temperature occurs at the interface; and (5) discontinuous changes (usually rises) in alpha particle abundance and flow speed relative to the protons occur at the interface. Stream interfaces do not generally recur on successive solar rotations, even though the streams in which they are embedded often do. At distances beyond several astronomical units, stream interfaces should be bounded by forward-reverse shock pairs; three of four reverse shocks observed at 1 AU during 1971--1974 were preceded within approx.1 day by stream interfaces. Our observations suggest that many streams close to the sun are bounded on all sides by large radial velocity shears separating rapidly expanding plasma from more slowly expanding plasma

    2018-04-01

    Full Text Available Tissue engineering aims to bring together biomaterials, cells, and signaling molecules within properly designed microenvironments in order to create viable treatment options for the lost or malfunctioning tissues. Design and production of scaffolds and cell-laden grafts that mimic the complex structural and functional features of tissues are among the most important elements of tissue engineering strategy. Although all tissues have their own complex structure, an even more complex case in terms of engineering a proper carrier material is encountered at the tissue interfaces, where two distinct tissues come together. The interfaces in the body can be examined in four categories; cartilage-bone and ligament-bone interfaces at the knee and the spine, tendon-bone interfaces at the shoulder and the feet, and muscle-tendon interface at the skeletal system. These interfaces are seen mainly at the soft-to-hard tissue transitions and they are especially susceptible to injury and tear due to the biomechanical inconsistency between these tissues where high strain fields are present. Therefore, engineering the musculoskeletal tissue interfaces remain a challenge. This review focuses on recent advancements in strategies for musculoskeletal interface engineering using different biomaterial-based platforms and surface modification techniques.

    A control interface for drivetrain braking provided by a regenerative brake and a non-regenerative brake is implemented using a combination of switches and graphic interface elements. The control interface comprises a control system for allocating drivetrain braking effort between the regenerative brake and the non-regenerative brake, a first operator actuated control for enabling operation of the drivetrain braking, and a second operator actuated control for selecting a target braking effort for drivetrain braking. A graphic display displays to an operator the selected target braking effort and can be used to further display actual braking effort achieved by drivetrain braking.

    Interfaces are back, or perhaps they never left. The familiar Socratic conceit from the Phaedrus, of communication as the process of writing directly on the soul of the other, has returned to center stage in today's discussions of culture and media. Indeed Western thought has long construed media as a grand choice between two kinds of interfaces. Following the optimistic path, media seamlessly interface self and other in a transparent and immediate connection. But, following the pessimistic path, media are the obstacles to direct communion, disintegrating self and other into misunderstanding

    Lloyd, Seth; Landahl, Andrew J.; Slotine, Jean-Jacques E.

    2004-01-01

    To observe or control a quantum system, one must interact with it via an interface. This article exhibits simple universal quantum interfaces--quantum input/output ports consisting of a single two-state system or quantum bit that interacts with the system to be observed or controlled. It is shown that under very general conditions the ability to observe and control the quantum bit on its own implies the ability to observe and control the system itself. The interface can also be used as a quantum communication channel, and multiple quantum systems can be connected by interfaces to become an efficient universal quantum computer. Experimental realizations are proposed, and implications for controllability, observability, and quantum information processing are explored

    The Scalable Coherent Interface (IEEE P1596) is establishing an interface standard for very high performance multiprocessors, supporting a cache-coherent-memory model scalable to systems with up to 64K nodes. This Scalable Coherent Interface (SCI) will supply a peak bandwidth per node of 1 GigaByte/second. The SCI standard should facilitate assembly of processor, memory, I/O and bus bridge cards from multiple vendors into massively parallel systems with throughput far above what is possible today. The SCI standard encompasses two levels of interface, a physical level and a logical level. The physical level specifies electrical, mechanical and thermal characteristics of connectors and cards that meet the standard. The logical level describes the address space, data transfer protocols, cache coherence mechanisms, synchronization primitives and error recovery. In this paper we address logical level issues such as packet formats, packet transmission, transaction handshake, flow control, and cache coherence. 11 refs., 10 figs

    Highlight: • This review article covers the topic of high temperature interface superconductivity. • New materials and techniques used for achieving interface superconductivity are discussed. • We emphasize the role played by the differences in structure and electronic properties at the interface with respect to the bulk of the constituents. - Abstract: High-T_c superconductivity at interfaces has a history of more than a couple of decades. In this review we focus our attention on copper-oxide based heterostructures and multi-layers. We first discuss the technique, atomic layer-by-layer molecular beam epitaxy (ALL-MBE) engineering, that enabled High-T_c Interface Superconductivity (HT-IS), and the challenges associated with the realization of high quality interfaces. Then we turn our attention to the experiments which shed light on the structure and properties of interfacial layers, allowing comparison to those of single-phase films and bulk crystals. Both ‘passive’ hetero-structures as well as surface-induced effects by external gating are discussed. We conclude by comparing HT-IS in cuprates and in other classes of materials, especially Fe-based superconductors, and by examining the grand challenges currently laying ahead for the field.

    MER SPICE Interface is a software module for use in conjunction with the Mars Exploration Rover (MER) mission and the SPICE software system of the Navigation and Ancillary Information Facility (NAIF) at NASA's Jet Propulsion Laboratory. (SPICE is used to acquire, record, and disseminate engineering, navigational, and other ancillary data describing circumstances under which data were acquired by spaceborne scientific instruments.) Given a Spacecraft Clock value, MER SPICE Interface extracts MER-specific data from SPICE kernels (essentially, raw data files) and calculates values for Planet Day Number, Local Solar Longitude, Local Solar Elevation, Local Solar Azimuth, and Local Solar Time (UTC). MER SPICE Interface was adapted from a subroutine, denoted m98SpiceIF written by Payam Zamani, that was intended to calculate SPICE values for the Mars Polar Lander. The main difference between MER SPICE Interface and m98SpiceIf is that MER SPICE Interface does not explicitly call CHRONOS, a time-conversion program that is part of a library of utility subprograms within SPICE. Instead, MER SPICE Interface mimics some portions of the CHRONOS code, the advantage being that it executes much faster and can efficiently be called from a pipeline of events in a parallel processing environment.

  17. Lectures on random interfaces

    CERN Document Server

    Funaki, Tadahisa

    2016-01-01

    Interfaces are created to separate two distinct phases in a situation in which phase coexistence occurs. This book discusses randomly fluctuating interfaces in several different settings and from several points of view: discrete/continuum, microscopic/macroscopic, and static/dynamic theories. The following four topics in particular are dealt with in the book. Assuming that the interface is represented as a height function measured from a fixed-reference discretized hyperplane, the system is governed by the Hamiltonian of gradient of the height functions. This is a kind of effective interface model called ∇φ-interface model. The scaling limits are studied for Gaussian (or non-Gaussian) random fields with a pinning effect under a situation in which the rate functional of the corresponding large deviation principle has non-unique minimizers. Young diagrams determine decreasing interfaces, and their dynamics are introduced. The large-scale behavior of such dynamics is studied from the points of view of the hyd...

    Real-time control of visual display systems via mid-air hand gestures offers many advantages over traditional interaction modalities. In medicine, for example, it allows a practitioner to adjust display values, e.g. contrast or zoom, on a medical visualization interface without the need to re-sterilize the interface. However, when users are holding a small tool (such as a pen, surgical needle, or computer stylus) the need to constantly put the tool down in order to make hand gesture interactions is not ideal. This work presents a novel interface that automatically adjusts for gesturing with hands and hand-held tools to precisely control medical displays. The novelty of our interface is that it uses a single set of gestures designed to be equally effective for fingers and hand-held tools without using markers. This type of interface was previously not feasible with low-resolution depth sensors such as Kinect, but is now achieved by using the recently released Leap Motion controller. Our interface is validated through a user study on a group of people given the task of adjusting parameters on a medical image.

    1991-11-01

    A workshop that explored materials and interfaces research needs relevant to national environmental concerns was conducted at Pacific Northwest Laboratory. The purposes of the workshop were to refine the scientific research directions being planned for the Materials and Interface Program in the Molecular Science Research Center (MSRC) and further define the research and user equipment to the included as part of the proposed Environmental and Molecular Science Laboratory (EMSL). Three plenary information sessions served to outline the background, objectives, and status of the MSRC and EMSL initiatives; selected specific areas with environmentally related materials; and the status of capabilities and facilities planned for the EMSL. Attention was directed to four areas where materials and interface science can have a significant impact on prevention and remediation of environmental problems: in situ detection and characterization of hazardous wastes (sensors), minimization of hazardous waste (separation membranes, ion exchange materials, catalysts), waste containment (encapsulation and barrier materials), and fundamental understanding of contaminant transport mechanisms. During all other sessions, the participants were divided into three working groups for detailed discussion and the preparation of a written report. The working groups focused on the areas of interface structure and chemistry, materials and interface stability, and materials synthesis. These recommendations and suggestions for needed research will be useful for other researchers in proposing projects and for suggesting collaborative work with MSRC researchers. 1 fig

    1987-01-01

    This book contains the proceedings of the first Workshop on Interface Phenomena, organized jointly by the surface science groups at Dalhousie University and the University of Maine. It was our intention to concentrate on just three topics related to the kinetics of interface reactions which, in our opinion, were frequently obscured unnecessarily in the literature and whose fundamental nature warranted an extensive discussion to help clarify the issues, very much in the spirit of the Discussions of the Faraday Society. Each session (day) saw two principal speakers expounding the different views; the session chairmen were asked to summarize the ensuing discussions. To understand the complexity of interface reactions, paradigms must be formulated to provide a framework for the interpretation of experimen­ tal data and for the construction of theoretical models. Phenomenological approaches have been based on a small number of rate equations for the concentrations or mole numbers of the various species involved i...

    Presents a novel interface synthesis approach based on a one-sided interface description. Whereas most other approaches consider interface synthesis as optimizing a channel to existing client/server modules, we consider the interface synthesis as part of the client/server module synthesis (which...... may contain the re-use of existing modules). The interface synthesis approach describes the basic transformations needed to transform the server interface description into an interface description on the client side of the communication medium. The synthesis approach is illustrated through a point...

  8. Hydro-Thermal Fatigue Resistance Measurements on Polymer Interfaces

    Science.gov (United States)

    Gurumurthy, Charan K.; Kramer, Edward J.; Hui, Chung-Yuen

    1998-03-01

    We have developed a new technique based on a fiber optic displacement sensor for rapid determination of hydro-thermal fatigue crack growth rate per cycle (da/dN) of an epoxy/polyimide interface used in flip chip attach microelectronic assembly. The sample is prepared as a trilayered cantilever beam by capillary flow of the epoxy underfill over a polyimide coated metallic beam. During hydro-thermal cycling the crack growth along the interface (from the free end) changes the displacement of this end of the beam and we measure the free end displacement at the lowest temperature in each hydro-thermal cycle. The change in beam displacement is then converted into crack growth rate (da/dN). da/dN depends on the maximum change in the strain energy release rate of the crack and the phase angle in each cycle. The relation between da/dN and maximum strain energy release rate characterizes the fatigue crack growth resistance of the interface. We have developed and used a simple model anhydride cured and a commercially available PMDA/ODA passivation for this study.

    1980-12-01

    Two aspects of surface nonlinear optics are explored in this thesis. The first part is a theoretical and experimental study of nonlinear intraction of surface plasmons and bulk photons at metal-dielectric interfaces. The second part is a demonstration and study of surface enhanced second harmonic generation at rough metal surfaces. A general formulation for nonlinear interaction of surface plasmons at metal-dielectric interfaces is presented and applied to both second and third order nonlinear processes. Experimental results for coherent second and third harmonic generation by surface plasmons and surface coherent antiStokes Raman spectroscopy (CARS) are shown to be in good agreement with the theory

    2010-07-01

    This special issue is devoted to illustrating important aspects and significant results in the field of modeling and simulation of water at interfaces with solutes or with confining substrates, focusing on a range of temperatures from ambient to supercooled. Understanding the behavior of water, in contact with different substrates and/or in solutions, is of pivotal importance for a wide range of applications in physics, chemistry and biochemistry. Simulations of confined and/or interfacial water are also relevant for testing how different its behavior is with respect to bulk water. Simulations and modeling in this field are of particular importance when studying supercooled regions where water shows anomalous properties. These considerations motivated the organization of a workshop at CECAM in the summer of 2009 which aimed to bring together scientists working with computer simulations on the properties of water in various environments with different methodologies. In this special issue, we collected a variety of interesting contributions from some of the speakers of the workshop. We have roughly classified the contributions into four groups. The papers of the first group address the properties of interfacial and confined water upon supercooling in an effort to understand the relation with anomalous behavior of supercooled bulk water. The second group deals with the specific problem of solvation. The next group deals with water in different environments by considering problems of great importance in technological and biological applications. Finally, the last group deals with quantum mechanical calculations related to the role of water in chemical processes. The first group of papers is introduced by the general paper of Stanley et al. The authors discuss recent progress in understanding the anomalies of water in bulk, nanoconfined, and biological environments. They present evidence that liquid water may display 'polymorphism', a property that can be present in

    1999-01-01

    Easy-to-use interfaces are a class of interfaces that fall between public access interfaces and graphical user interfaces in usability and cognitive difficulty. We describe characteristics of easy-to-use interfaces by the properties of four dimensions: selection, navigation, direct manipulation, and contextual metaphors. Another constraint we introduced was to include as little text as possible, and what text we have will be in at least four languages. Formative evaluations were conducted to identify and isolate these characteristics. Our application is a visual interface for a home automation system intended for a diverse set of users. The design will be expanded to accommodate the visually disabled in the near future

    Nuclear power plant data are received at the Operations Center of the Consejo de Seguridad Nuclear in emergency situations. In order to achieve the required interface and to prepare those data to perform simulation and forecasting with already existing computer codes a Safety Parameters Graphical Interface (IGPS) has been developed. The system runs in a UNIX environment and use the Xwindows capabilities. The received data are stored in such a way that it can be easily used for further analysis and training activities. The system consists of task-oriented modules (processes) which communicate each other using well known UNIX mechanisms (signals, sockets and shared memory segments). IGPS conceptually have two different parts: Data collection and preparation, and Data monitorization. (Author)

    At the birth of participatory design, there was a strong political consciousness surrounding the design of new technology, the design process in particular, establishing a rich set of methods and tools for user-centered design. Today, the term design has extended its scope of concern beyond...... the process of design and into how users interact with the designed product on a day-to-day basis. This paper is an attempt to call to attention the need for a new set of methods, attitudes and approaches, along with the existing, to discuss, analyze and reflect upon the politics at the interface....... By presenting a critical analysis of two design cases, we elicit the importance of such an agenda and the implications for design in doing so. We use the Foucauldian notion of power to analyze the power relationships in these two cases and to articulate the politics at the interface. We conclude by emphasizing...

  5. The technical supervision interface

    Sollander, P

    1998-01-01

    The Technical Control Room (TCR) is currently using 30 different applications for the remote supervision of the technical infrastructure at CERN. These applications have all been developed with the CERN made Uniform Man Machine Interface (UMMI) tools built in 1990. However, the visualization technology has evolved phenomenally since 1990, the Technical Data Server (TDS) has radically changed our control system architecture, and the standardization and the maintenance of the UMMI applications have become important issues as their number increases. The Technical Supervision Interface is intended to replace the UMMI and solve the above problems. Using a standard WWW-browser for the display, it will be inherently multi-platform and hence available for control room operators, equipment specialists and on-call personnel.

  14. NESSUS/NASTRAN Interface

    Science.gov (United States)

    Millwater, Harry; Riha, David

    1996-01-01

    The NESSUS probabilistic analysis computer program has been developed with a built-in finite element analysis program NESSUS/FEM. However, the NESSUS/FEM program is specialized for engine structures and may not contain sufficient features for other applications. In addition, users often become well acquainted with a particular finite element code and want to use that code for probabilistic structural analysis. For these reasons, this work was undertaken to develop an interface between NESSUS and NASTRAN such that NASTRAN can be used for the finite element analysis and NESSUS can be used for the probabilistic analysis. In addition, NESSUS was restructured such that other finite element codes could be more easily coupled with NESSUS. NESSUS has been enhanced such that NESSUS will modify the NASTRAN input deck for a given set of random variables, run NASTRAN and read the NASTRAN result. The coordination between the two codes is handled automatically. The work described here was implemented within NESSUS 6.2 which was delivered to NASA in September 1995. The code runs on Unix machines: Cray, HP, Sun, SGI and IBM. The new capabilities have been implemented such that a user familiar with NESSUS using NESSUS/FEM and NASTRAN can immediately use NESSUS with NASTRAN. In other words, the interface with NASTRAN has been implemented in an analogous manner to the interface with NESSUS/FEM. Only finite element specific input has been changed. This manual is written as an addendum to the existing NESSUS 6.2 manuals. We assume users have access to NESSUS manuals and are familiar with the operation of NESSUS including probabilistic finite element analysis. Update pages to the NESSUS PFEM manual are contained in Appendix E. The finite element features of the code and the probalistic analysis capabilities are summarized.

  15. Transport processes at fluidic interfaces

    CERN Document Server

    Reusken, Arnold

    2017-01-01

    There are several physico-chemical processes that determine the behavior of multiphase fluid systems – e.g., the fluid dynamics in the different phases and the dynamics of the interface(s), mass transport between the fluids, adsorption effects at the interface, and transport of surfactants on the interface – and result in heterogeneous interface properties. In general, these processes are strongly coupled and local properties of the interface play a crucial role. A thorough understanding of the behavior of such complex flow problems must be based on physically sound mathematical models, which especially account for the local processes at the interface. This book presents recent findings on the rigorous derivation and mathematical analysis of such models and on the development of numerical methods for direct numerical simulations. Validation results are based on specifically designed experiments using high-resolution experimental techniques. A special feature of this book is its focus on an interdisciplina...

    The localized magnons at an interface between two Heisenberg ferromagnets and the ferromagnetic stability at the interface are studied. The authors consider simple cubic crystals having the same lattice parameter and the same spin value in the fundamental state on each site, but different exchange integrals between first and second nearest neighbours. An interface by coupling two semi-infinite crystals having the same crystallographic surface is defined. The conditions for the existence of localized magnons at (001) interfaces as well as the dispersion curves of localized and resonant magnons in the high symmetry directions of the Brillouin zone are studied. The effect of the interface interactions on these modes is determined. It is shown that magnetic superstructures may exist at (110) interfaces. Such an instability is given by the existence of a soft localized mode at the interface [fr

    1979-01-01

    The increase of the superconducting transition temperature Tsub(c) due to the tunneling of conduction electrons into negative-u centers at a disordered metal-semiconductor interface is calculated. The strong dependence of the experimental increase of Tsub(c) on the Fermi energy of the metal is accounted for by the polaronic reduction of the tunneling matrix elements. The latter reduction is dynamically suppressed by the decreasing lifetime of the localized state as Esub(F) increases. The theoretical enhancement is sufficiently strong to explain the increase of Tsub(c) observed in eutectic alloys. (author)

The analysis shows that the current state-of-art is featured by three aspects: Firstly internalism, in that the papers adress the tech­nologies in their own right with little con­text­ualization, secondly whiggism...... in that they largely address prevailing UI techno­logies, and thirdly history from above in that they focus on the great deeds of the visionaries. The paper then compares this state-of-art in UI history to the much more mature fields history of computing and history of technology. Based hereon, some speculations......The user interface is coming of age. Papers adressing UI history have appeared in fair amounts in the last 25 years.

  5. Interfaces naturais e o reconhecimento das línguas de sinais

    Directory of Open Access Journals (Sweden)

    Renato Kimura da Silva

    2017-01-01

    Full Text Available Interface é uma camada intermediária que está entre duas faces. No contexto computacional, podemos dizer que interface existe na intermediação interativa entre dois sujeitos, ou ainda entre sujeito e um programa. Ao longo dos anos, as interfaces têm evoluído constantemente: das linhas de texto monocromáticas aos mouses - com o conceito exploratório da interface gráfica - até as mais recentes interfaces naturais - ubíquas e que objetivam a transparência da interação. Nas novas interfaces, por meio do uso do corpo, o usuário interage com o computador, não sendo necessário aprender a interface. Seu uso é mais intuitivo, com a possibilidade de reconhecimento da voz, da face e dos gestos. O avanço tecnológico vai ao encontro das necessidades básicas do indivíduo, como a comunicação, tornando-se factível conceber novas tecnologias que beneficiam pessoas em diferentes esferas. A contribuição desse trabalho está em entender o cenário técnico que possibilita idealizar e criar interfaces naturais para o reconhecimento automático computacional dos sinais das Línguas de Sinais e considerável parte de sua gramática. Para tanto, essa pesquisa foi primeiramente pautada no estudo do desenvolvimento das interfaces computacionais e da sua estreita relação com os videogames, fundamentando-se nas contribuições de autores como Pierre Lévy, Sherry Turkle, Janet Murray e Louise Poissant. Em momento posterior, aproximamo-nos de autores como William Stokoe, Scott Liddell, Ray Birdwhistell, Lúcia Santaella e Winfried Nõth, a respeito de temas gerais e específicos que abarcam a multidisciplinaridade das Línguas de Sinais, suas gramáticas e aspectos semióticos. Por fim, foi realizado um levantamento do Estado da Arte das Interfaces Naturais voltadas ao Reconhecimento Automático das Línguas de Sinais, além do estudo de pesquisas notáveis relacionadas ao tema, apresentando possíveis caminhos futuros a serem trilhados por

  6. Combinatorial Nano-Bio Interfaces.

    2018-06-08

    Nano-bio interfaces are emerging from the convergence of engineered nanomaterials and biological entities. Despite rapid growth, clinical translation of biomedical nanomaterials is heavily compromised by the lack of comprehensive understanding of biophysicochemical interactions at nano-bio interfaces. In the past decade, a few investigations have adopted a combinatorial approach toward decoding nano-bio interfaces. Combinatorial nano-bio interfaces comprise the design of nanocombinatorial libraries and high-throughput bioevaluation. In this Perspective, we address challenges in combinatorial nano-bio interfaces and call for multiparametric nanocombinatorics (composition, morphology, mechanics, surface chemistry), multiscale bioevaluation (biomolecules, organelles, cells, tissues/organs), and the recruitment of computational modeling and artificial intelligence. Leveraging combinatorial nano-bio interfaces will shed light on precision nanomedicine and its potential applications.

    Auwärter, Willi; Écija, David; Klappenberger, Florian; Barth, Johannes V.

    2015-02-01

    Porphyrins and other tetrapyrrole macrocycles possess an impressive variety of functional properties that have been exploited in natural and artificial systems. Different metal centres incorporated within the tetradentate ligand are key for achieving and regulating vital processes, including reversible axial ligation of adducts, electron transfer, light-harvesting and catalytic transformations. Tailored substituents optimize their performance, dictating their arrangement in specific environments and mediating the assembly of molecular nanoarchitectures. Here we review the current understanding of these species at well-defined interfaces, disclosing exquisite insights into their structural and chemical properties, and also discussing methods by which to manipulate their intramolecular and organizational features. The distinct characteristics arising from the interfacial confinement offer intriguing prospects for molecular science and advanced materials. We assess the role of surface interactions with respect to electronic and physicochemical characteristics, and describe in situ metallation pathways, molecular magnetism, rotation and switching. The engineering of nanostructures, organized layers, interfacial hybrid and bio-inspired systems is also addressed.

  10. APST interfaces in LINCS

    Energy Technology Data Exchange (ETDEWEB)

    Fletcher, J.G.

    1995-07-01

    APST is an acronym for the four highest of the seven layers of the LINCS hierarchy of communication protocols: (from high to low) Application, Presentation, Session, and Transport. Routines in each but the lowest of these APST layers can utilize the facilities of any lower APST layer (normally, but not necessarily, the immediately next lower layer) by invoking various primitives (macros that in most cases are subroutine calls) defining the upper interface of the lower layer. So there are three APST interfaces: Presentation layer, used by the Application layer; Session layer, normally used by the Presentation layer; and Transport layer, normally used by the Session layer. Logically, each end of a stream (unidirectional sequence of transmitted information) is handled by three modules, one module each for the Presentation, Session, and Transport layers, and each of these modules deals with only that one end of that one stream. The internal workings of the layers, particularly the Transport layer, do not necessarily exhibit this same modularization; for example, the two oppositely directed streams between the same two ends (constituting an association) may interact within a layer. However, such interaction is an implementational detail of no direct interest to those utilizing the layer. The present document does not describe implementation, nor does it discuss in any detail how the modules employ packet headings and data formats to communicate with their partner modules at the other end of a stream. There being one logical module per end of stream is a characteristic only of the Presentation, Session, and Transport layers. An Application layer module usually manages several streams, orchestrating them to achieve some desired purpose. The modules of the layers (Network, Link, and Physical) below the APST layers each handle many streams, multiplexing them through the nodes and channels of the network to transmit them from their origins to their destinations.

    Full Text Available A preocupação fundamenta! do trabalho é de caráter ontológico: esboçar o problema das significações apriorísticas e autônomas dos elementos que compõem a sintaxe arquitetônica. O trabalho elege um desses elementos: a janela. Este artigo parte da aproximação histórica entre a janela e a secção da pirâmide visual, construção imaginária da teoria da perspectiva renascentista. A consideração da janela na linguagem arquitetônica implica reconhecer uma ambigüidade essencial: a janela deve inserir-se ordenadamente no plano da parede - raciocínio típico da modenatura - mas também relacionar-se com a imagem vista através dela, que extrapola o plano, ressaltando a tridimensionalidade - herança da perspectiva renascentista, fundamentada no espaço euclidiano. Ver janela ou ver através da janela são alternativas que se colocam tanto ao observador interno ao edifício, quanto ao externo.

    International Nuclear Information System (INIS)

    Kropik, M.; Matejka, K.; Sklenka, L.; Chab, V.

    2002-01-01

    The article describes a new human-machine interface that was installed at the VR-1 training reactor. The human-machine interface upgrade was completed in the summer 2001. The interface was designed with respect to functional, ergonomic and aesthetic requirements. The interface is based on a personal computer equipped with two displays. One display enables alphanumeric communication between the reactor operator and the nuclear reactor I and C. The second display is a graphical one. It presents the status of the reactor, principal parameters (as power, period), control rods positions, course of the reactor power. Furthermore, it is possible to set parameters, to show the active core configuration, to perform reactivity calculations, etc. The software for the new human-machine interface was produced with the InTouch developing tool of the Wonder-Ware Company. It is possible to switch the language of the interface between Czech and English because of many foreign students and visitors to the reactor. Microcomputer based communication units with proper software were developed to connect the new human-machine interface with the present reactor I and C. The new human-machine interface at the VR-1 training reactor improves the comfort and safety of the reactor utilisation, facilitates experiments and training, and provides better support for foreign visitors.

  2. ATLAS Detector Interface Group

    CERN Multimedia

    Mapelli, L

    Originally organised as a sub-system in the DAQ/EF-1 Prototype Project, the Detector Interface Group (DIG) was an information exchange channel between the Detector systems and the Data Acquisition to provide critical detector information for prototype design and detector integration. After the reorganisation of the Trigger/DAQ Project and of Technical Coordination, the necessity to provide an adequate context for integration of detectors with the Trigger and DAQ lead to organisation of the DIG as one of the activities of Technical Coordination. Such an organisation emphasises the ATLAS wide coordination of the Trigger and DAQ exploitation aspects, which go beyond the domain of the Trigger/DAQ project itself. As part of Technical Coordination, the DIG provides the natural environment for the common work of Trigger/DAQ and detector experts. A DIG forum for a wide discussion of all the detector and Trigger/DAQ integration issues. A more restricted DIG group for the practical organisation and implementation o...

    Power User Interface 5.0 (PUI) is a system of middleware, written for expert users in the Earth-science community, PUI enables expedited ordering of data granules on the basis of specific granule-identifying information that the users already know or can assemble. PUI also enables expert users to perform quick searches for orderablegranule information for use in preparing orders. PUI 5.0 is available in two versions (note: PUI 6.0 has command-line mode only): a Web-based application program and a UNIX command-line- mode client program. Both versions include modules that perform data-granule-ordering functions in conjunction with external systems. The Web-based version works with Earth Observing System Clearing House (ECHO) metadata catalog and order-entry services and with an open-source order-service broker server component, called the Mercury Shopping Cart, that is provided separately by Oak Ridge National Laboratory through the Department of Energy. The command-line version works with the ECHO metadata and order-entry process service. Both versions of PUI ultimately use ECHO to process an order to be sent to a data provider. Ordered data are provided through means outside the PUI software system.

    The PanDA (Production and Distributed Analysis) Workload Management System is used for ATLAS distributed production and analysis worldwide. The needs of ATLAS global computing imposed challenging requirements on PanDA design in areas such as scalability, robustness, automation, diagnostics, and usability for both production shifters and analysis users. Important to meeting these and other requirements is a comprehensive monitoring system. Through a system-wide job database, the PanDA monitor provides a comprehensive and coherent view of the system and job execution, from high level summaries to detailed drill-down job diagnostics. It is (like the rest of PanDA) an Apache-based Python application backed by Oracle. The presentation layer is HTML code generated on the fly in the Python application which is also responsible for managing database queries. However, this approach is lacking in user interface flexibility, simplicity of communication with external systems, and ease of maintenance. We decided to migrat...

  7. Nanoparticle Assemblies at Fluid Interfaces

    Energy Technology Data Exchange (ETDEWEB)

    Russell, Thomas P. [Univ. of Massachusetts, Amherst, MA (United States). Dept. of Polymer Science and Engineering

    2015-03-10

    A systematic study of the structure and dynamics of nanoparticles (NP) and NP-surfactants was performed. The ligands attached to both the NPs and NP-surfactants dictate the manner in which the nanoscopic materials assemble at fluid interfaces. Studies have shown that a single layer of the nanoscpic materials form at the interface to reduce the interactions between the two immiscible fluids. The shape of the NP is, also, important, where for spherical particles, a disordered, liquid-like monolayer forms, and, for nanorods, ordered domains at the interface is found and, if the monolayers are compressed, the orientation of the nanorods with respect to the interface can change. By associating end-functionalized polymers to the NPs assembled at the interface, NP-surfactants are formed that increase the energetic gain in segregating each NP at the interface which allows the NP-surfactants to jam at the interface when compressed. This has opened the possibility of structuring the two liquids by freezing in shape changes of the liquids.

    An OSF/Motif-based graphical user interface has been developed to facilitate the use of the database and data analysis software packages available from the High Energy Astrophysics Science Archive Research Center (HEASARC). It can also be used as an interface to other, similar, routines. A small number of tables are constructed to specify the possible commands and command parameters for a given set of analysis routines. These tables can be modified by a designer to affect the appearance of the interface screens. They can also be dynamically changed in response to parameter adjustments made while the underlying program is running. Additionally, a communication protocol has been designed so that the interface can operate locally or across a network. It is intended that this software be able to run on a variety of workstations and X terminals.

    TensorFlow is a second-generation open-source machine learning software library with a built-in framework for implementing neural networks in wide variety of perceptual tasks. Although TensorFlow usage is well established with computer vision datasets, the TensorFlow interface with DICOM formats for medical imaging remains to be established. Our goal is to extend the TensorFlow API to accept raw DICOM images as input; 1513 DaTscan DICOM images were obtained from the Parkinson's Progression Markers Initiative (PPMI) database. DICOM pixel intensities were extracted and shaped into tensors, or n-dimensional arrays, to populate the training, validation, and test input datasets for machine learning. A simple neural network was constructed in TensorFlow to classify images into normal or Parkinson's disease groups. Training was executed over 1000 iterations for each cross-validation set. The gradient descent optimization and Adagrad optimization algorithms were used to minimize cross-entropy between the predicted and ground-truth labels. Cross-validation was performed ten times to produce a mean accuracy of 0.938 ± 0.047 (95 % CI 0.908-0.967). The mean sensitivity was 0.974 ± 0.043 (95 % CI 0.947-1.00) and mean specificity was 0.822 ± 0.207 (95 % CI 0.694-0.950). We extended the TensorFlow API to enable DICOM compatibility in the context of DaTscan image analysis. We implemented a neural network classifier that produces diagnostic accuracies on par with excellent results from previous machine learning models. These results indicate the potential role of TensorFlow as a useful adjunct diagnostic tool in the clinical setting.

  7. Output control of da Vinci surgical system's surgical graspers.

    The number of robot-assisted surgeries performed with the da Vinci surgical system has increased significantly over the past decade. The articulating movements of the robotic surgical grasper are controlled by grip controls at the master console. The user interface has been implicated as one contributing factor in surgical grasping errors. The goal of our study was to characterize and evaluate the user interface of the da Vinci surgical system in controlling surgical graspers. An angular manipulator with force sensors was used to increment the grip control angle as grasper output angles were measured. Input force at the grip control was simultaneously measured throughout the range of motion. Pressure film was used to assess the maximum grasping force achievable with the endoscopic grasping tool. The da Vinci robot's grip control angular input has a nonproportional relationship with the grasper instrument output. The grip control mechanism presents an intrinsic resistant force to the surgeon's fingertips and provides no haptic feedback. The da Vinci Maryland graspers are capable of applying up to 5.1 MPa of local pressure. The angular and force input at the grip control of the da Vinci robot's surgical graspers is nonproportional to the grasper instrument's output. Understanding the true relationship of the grip control input to grasper instrument output may help surgeons understand how to better control the surgical graspers and promote fewer grasping errors.

    The study of semiconductor interfaces is one of the most active and exciting areas of current semiconductor research. Because interfaces play a vital role in modern semiconductor technology (integrated circuits, heterojunction lasers, solar cells, infrared detectors, etc.), there is a strong incentive to understand interface properties at a fundamental level and advance existing technology thereby. At the same time, technological advances such as molecular beam epitaxy have paved the way for the fabrication of semiconductor heterojunctions and superlattices of novel design which exhibit unusual electronic, optical, and magnetic properties and offer unique opportunities for fundamental scientific research. A general perspective on this subject is offered treating such topics as the atomic and electronic structure of semiconductor surfaces and interfaces; oxidation and oxide layers; semiconductor heterojunctions and superlattices; rectifying metal-semiconductor contacts; and interface reactions. Recent progress is emphasized and some future directions are indicated. In addition, the role that large-scale scientific computation has played in furthering our theoretical understanding of semiconductor surfaces and interfaces is discussed. Finally, the nature of theoretical models, and the role they play in describing the physical world is considered.

    the stakes against those who might want to enter. Laboratory sciences interface nature in a peculiar way: by barring real natural objects from entering the lab and by substituting for them reconfigured versions of these objects to work with in research. These supplemental versions of natural objects do refer back to natural processes or conditions, but at the same time they are also autonomous new objects and processes with differential qualities and reproductive powers within laboratory contexts. Laboratory sciences have the disadvantage that their products must be freshly contextualized when they leave the lab to reenter natural environments. In the natural sciences, re-contextualization is often accomplished by transferring some of the conditions that obtained in the lab onto the natural environment. Re-contextualization in the natural sciences may also just be a metaphor for a long chain of processes, involving specialized disciplines, by which some natural scientific results are used to create technologies which are then used in practice - a process that often fails, involves political strategies of persuasion and other complications. Contextualization involves adaptation not only to new laboratory external physical environments but also to the social world. One direction of social science research maintains that a form of (re) contextualization of a much larger scope and impact is evident today in contemporary societies, affecting in tendency all sciences and technological fields. This assessment is encapsulated in the idea that we have progressed from Mode 1 science and technology to a Mode 2 situation where knowledge is generated in the context of application and implication.

O presente trabalho trata da aplicação do modelo hidrossedimentológico “Soil And Water Assessment Tool” nas Sub-Bacias 2 e 1 da Bacia Experimental de São João do Cariri. O modelo com a interface ArcSWAT, que se une ao SIG, necessita da entrada de “Modelo Digital de Elevação” (MDE da bacia e as simulações foram realizadas utilizando dois MDEs para fins de análise comparativa: um originado a partir da interpolação de dados de campo e outro obtido através de sensoriamento remoto. Com isto foi possível verificar a confiabilidade do uso de MDE obtido por sensoriamento remoto. Em nível das sub-bacias experimentais, foi realizada a parametrização, na Sub-Bacia 2, e a validação, na Sub-Bacia 1. O desempenho do modelo, para a geração da lâmina escoada, foi avaliado pelo coeficiente de determinação (R² e do fator da eficiência de Nash-Sutcliffe. Os resultados mostram desempenho satisfatório para ambos os MDEs, mostrando a pouca sensibilidade da topografia da geração de lâmina simulada em pequenas bacias.

Esse tema é objeto tanto da área de marketing estratégico quanto da de estratégia empresarial. Nas duas áreas, há um ponto de consenso que afirma que a empresa deve diferenciar sua oferta para conquistar e manter vantagem competitiva. Mas, os estudos conduzidos por meio do modelo de Campos e Armas da Competição revelaram que a empresa pode diferenciar seu produto e/ou serviço de modo mais amplo, levando em consideração, na formulação da sua estratégia competitiva, também o campo da competição, quer do produto, quer dela própria. Assim, o objetivo deste artigo é evidenciar que, para a empresa ser competitiva, além de diferenciar seu produto e/ou seu serviço no sentido tradicional, ela precisa: 1 diferenciar seu produto incluindo a definição em quais campos vai competir em cada segmento; e 2 escolher as armas da competição que irá utilizar e definir a intensidade de cada arma. Para atingir tal objetivo, foram necessários vários conceitos do modelo de Campos e Armas da Competição: campo da competição, arma da competição, tese do modelo, configuração dos campos da competição, campo coadjuvante, produto coadjuvante e par produto-mercado. Como uma proposta inovadora sempre desperta dúvida, é mostrado o processo de validação do modelo de Campos e Armas da Competição e são discutidas sua universalidade, consistência e completude.

  19. PREFACE: Functionalized Liquid Liquid Interfaces

    Most natural processes take place at interfaces. For this reason, surface science has been a focal point of modern research. At solid-liquid interfaces one can induce various species to adsorb or react, and thus may study interactions between the substrate and adsorbates, kinetic processes, optical properties, etc. Liquid-liquid interfaces, formed by immiscible liquids such as water and oil, have a number of distinctive features. Both sides of the interface are amenable to detailed physical and chemical analysis. By chemical or electrochemical means, metal or semiconductor nanoparticles can be formed or localised at the interface. Surfactants can be used to tailor surface properties, and also to place organic molecular or supermolecular constructions at the boundary between the liquids. Electric fields can be used to drive ions from one fluid to another, or even change the shape of the interface itself. In many cases, both liquids are optically transparent, making functionalized liquid-liquid interfaces promising for various optical applications based on the transmission or reflection of light. An advantage common to most of these systems is self-assembly; because a liquid-liquid interface is not mechanically constrained like a solid-liquid interface, it can easily access its most stable state, even after it has been driven far from equilibrium. This special issue focuses on four modes of liquid-liquid interfacial functionalization: the controlled adsorption of molecules or nanoparticles, the formation of adlayers or films, electrowetting, and ion transfer or interface-localized reactions. Interfacial adsorption can be driven electrically, chemically, or mechanically. The liquid-liquid interface can be used to study how anisotropic particles orient at a surface under the influence of a field, how surfactants interact with other adsorbates, and how nanoparticles aggregate; the transparency of the interface also makes the chirality of organic adsorbates amenable to

  5. XML Translator for Interface Descriptions

    Science.gov (United States)

    Boroson, Elizabeth R.

    2009-01-01

    A computer program defines an XML schema for specifying the interface to a generic FPGA from the perspective of software that will interact with the device. This XML interface description is then translated into header files for C, Verilog, and VHDL. User interface definition input is checked via both the provided XML schema and the translator module to ensure consistency and accuracy. Currently, programming used on both sides of an interface is inconsistent. This makes it hard to find and fix errors. By using a common schema, both sides are forced to use the same structure by using the same framework and toolset. This makes for easy identification of problems, which leads to the ability to formulate a solution. The toolset contains constants that allow a programmer to use each register, and to access each field in the register. Once programming is complete, the translator is run as part of the make process, which ensures that whenever an interface is changed, all of the code that uses the header files describing it is recompiled.

    Traditionally the interaction between users and the Grid is done with command line tools. However, these tools are difficult to use by non-expert users providing minimal help and generating outputs not always easy to understand especially in case of errors. Graphical User Interfaces are typically limited to providing access to the monitoring or accounting information and concentrate on some particular aspects failing to cover the full spectrum of grid control tasks. To make the Grid more user friendly more complete graphical interfaces are needed. Within the DIRAC project we have attempted to construct a Web based User Interface that provides means not only for monitoring the system behavior but also allows to steer the main user activities on the grid. Using DIRAC's web interface a user can easily track jobs and data. It provides access to job information and allows performing actions on jobs such as killing or deleting. Data managers can define and monitor file transfer activity as well as check requests set by jobs. Production managers can define and follow large data productions and react if necessary by stopping or starting them. The Web Portal is build following all the grid security standards and using modern Web 2.0 technologies which allow to achieve the user experience similar to the desktop applications. Details of the DIRAC Web Portal architecture and User Interface will be presented and discussed.

    When designing "interfaces for everyone" for interactive systems, it is important to consider factors such as cost, the intended market, the state of the environment, etc. User interfaces are fundamental for the developmental process in any application, and its design must be contemplated from the start. Of the distinct parts of a system (hardware and software), it is the interface that permits the user access to computer resources. The seven principles of "Universal Design" or "Design for Everyone" focus on a universal usable design, but at the same time acknowledge the influences of internal and external factors. Structural changes in social and health services could provide an increase in the well-being of a country's citizens through the use of self-care programming and proactive management/prevention of disease. Automated home platforms can act as an accessibility instrument which permits users to avoid, compensate, mitigate, or neutralize the deficiencies and dependencies caused by living alone.

    The anode/electrolyte interface in solid oxide fuel cells (SOFC) is known to cause electrical losses. Geometrically simple Ni/yttria-stabilised zirconia (YSZ) interfaces were examined to gain information on the structural and chemical changes occurring during experiments at 1000°C in an atmosphere...... of 97% H2/3% H2O. Electrochemical impedance spectroscopy at open circuit voltage (OCV) and at anodic and cathodic polarisations (100 mV) was performed. A correlation of the electrical data with the structure development and the chemical composition was attempted. Nickel wires with different impurity...... between polarised and non-polarised samples. With pure nickel wires, however, the microstructures depended on the polarisation/non-polarisation conditions. At non-polarised conditions a hill and valley type structure was found. Anodic polarisation produced an up to 1 μm thick interface layer consisting...

    The neutron multichannel collimator diagnostic on TFTR is run with the help of a keyboard-entered interface language. The language allows the user to interact with the real-time control and data analysis systems in a consistent and efficient manner. It uses a vocabulary that can be abbreviated into one character commands which the proficient user may concatenate into command words. This allows the user to progress quickly from a novice to an expert operating mode. A similar type interface language could be applied to many interactive applications accepting keyboard inputs

    In the years since Jakob Nielsen's classic collection on interface consistency first appeared, much has changed, and much has stayed the same. On the one hand, there's been exponential growth in the opportunities for following or disregarding the principles of interface consistency-more computers, more applications, more users, and of course the vast expanse of the Web. On the other, there are the principles themselves, as persistent and as valuable as ever. In these contributed chapters, you'll find details on many methods for seeking and enforcing consistency, along with bottom-line analys

  4. A database for TMT interface control documents

    Science.gov (United States)

    Gillies, Kim; Roberts, Scott; Brighton, Allan; Rogers, John

    2016-08-01

    The TMT Software System consists of software components that interact with one another through a software infrastructure called TMT Common Software (CSW). CSW consists of software services and library code that is used by developers to create the subsystems and components that participate in the software system. CSW also defines the types of components that can be constructed and their roles. The use of common component types and shared middleware services allows standardized software interfaces for the components. A software system called the TMT Interface Database System was constructed to support the documentation of the interfaces for components based on CSW. The programmer describes a subsystem and each of its components using JSON-style text files. A command interface file describes each command a component can receive and any commands a component sends. The event interface files describe status, alarms, and events a component publishes and status and events subscribed to by a component. A web application was created to provide a user interface for the required features. Files are ingested into the software system's database. The user interface allows browsing subsystem interfaces, publishing versions of subsystem interfaces, and constructing and publishing interface control documents that consist of the intersection of two subsystem interfaces. All published subsystem interfaces and interface control documents are versioned for configuration control and follow the standard TMT change control processes. Subsystem interfaces and interface control documents can be visualized in the browser or exported as PDF files.

    2009-05-01

    Full Text Available O presente trabalho tem por objetivo tentar compreender a produção da imagem visual no teatro. Para isso se vale da apropriação livre do conceito de “dobra? de Gilles Deleuze para se referir à multiplicidade de imagens criadas pelas diversas modalidades artísticas. Como no teatro há o entrelaçamento de imagens verbais – palavras enunciadas pelo texto dramático ou teatral – com imagens visuais – a visualidade advinda da composição cênica concreta que organiza no espaço ator e objeto –, a ênfase só podia recair sobre estas duas formas imagéticas. No caso do teatro, surge ainda a percepção de que para além da materialidade da cena, outras imagens emergem do confronto entre palco e platéia. Nesse sentido, imagem teatral seria então aquilo que surge da interação entre ator e espectador. A contribuição desse trabalho pode estar no fato de atualizar certos conceitos sobre a criação da imagem poética na poesia e no cinema para aplicá-los ao teatro. Ao recuperar o pensa-mento de Otávio Paz, Alfredo Bosi, Sergei Eisenstein, entre outros, bus-ca-se promover uma reflexão mais aprofundada sobre a construção visual no teatro.

  1. Properties and determination of the interface stiffness

    International Nuclear Information System (INIS)

    Du Danxu; Zhang Hao; Srolovitz, David J.

    2007-01-01

    The chemical potential of a curved interface contains a term that is proportional to the product of the interface curvature and the interface stiffness. In crystalline materials, the interface stiffness is a tensor. This paper examines several basic issues related to the properties of the interface stiffness, especially the determination of the interface stiffness in particular directions (i.e. the commonly used scalar form of the interface stiffness). Of the five parameters that describe an arbitrary grain boundary, only those describing the inclination are crucial for the scalar stiffness. We also examine the influence of crystal symmetry on the stiffness tensor for both free surfaces and grain boundaries. This results in substantial simplifications for cases in which interfaces possess mirror or rotational symmetries. An efficient method for determining the interface stiffness tensor using atomistic simulations is proposed

  2. Ionic Structure at Dielectric Interfaces

    Science.gov (United States)

    Jing, Yufei

    The behavior of ions in liquids confined between macromolecules determines the outcome of many nanoscale assembly processes in synthetic and biological materials such as colloidal dispersions, emulsions, hydrogels, DNA, cell membranes, and proteins. Theoretically, the macromolecule-liquid boundary is often modeled as a dielectric interface and an important quantity of interest is the ionic structure in a liquid confined between two such interfaces. The knowledge gleaned from the study of ionic structure in such models can be useful in several industrial applications, such as biosensors, lithium-ion batteries double-layer supercapacitors for energy storage and seawater desalination. Electrostatics plays a critical role in the development of such functional materials. Many of the functions of these materials, result from charge and composition heterogeneities. There are great challenges in solving electrostatics problems in heterogeneous media with arbitrary shapes because electrostatic interactions remains unknown but depend on the particular density of charge distributions. Charged molecules in heterogeneous media affect the media's dielectric response and hence the interaction between the charges is unknown since it depends on the media and on the geometrical properties of the interfaces. To determine the properties of heterogeneous systems including crucial effects neglected in classical mean field models such as the hard core of the ions, the dielectric mismatch and interfaces with arbitrary shapes. The effect of hard core interactions accounts properly for short range interactions and the effect of local dielectric heterogeneities in the presence of ions and/or charged molecules for long-range interactions are both analyzed via an energy variational principle that enables to update charges and the medium's response in the same simulation time step. In particular, we compute the ionic structure in a model system of electrolyte confined by two planar dielectric

  8. The Integrated Mode Management Interface

    1996-01-01

    Mode management is the processes of understanding the character and consequences of autoflight modes, planning and selecting the engagement, disengagement and transitions between modes, and anticipating automatic mode transitions made by the autoflight system itself. The state of the art is represented by the latest designs produced by each of the major airframe manufacturers, the Boeing 747-400, the Boeing 777, the McDonnell Douglas MD-11, and the Airbus A320/A340 family of airplanes. In these airplanes autoflight modes are selected by manipulating switches on the control panel. The state of the autoflight system is displayed on the flight mode annunciators. The integrated mode management interface (IMMI) is a graphical interface to autoflight mode management systems for aircraft equipped with flight management computer systems (FMCS). The interface consists of a vertical mode manager and a lateral mode manager. Autoflight modes are depicted by icons on a graphical display. Mode selection is accomplished by touching (or mousing) the appropriate icon. The IMMI provides flight crews with an integrated interface to autoflight systems for aircraft equipped with flight management computer systems (FMCS). The current version is modeled on the Boeing glass-cockpit airplanes (747-400, 757/767). It runs on the SGI Indigo workstation. A working prototype of this graphics-based crew interface to the autoflight mode management tasks of glass cockpit airplanes has been installed in the Advanced Concepts Flight Simulator of the CSSRF of NASA Ames Research Center. This IMMI replaces the devices in FMCS equipped airplanes currently known as mode control panel (Boeing), flight guidance control panel (McDonnell Douglas), and flight control unit (Airbus). It also augments the functions of the flight mode annunciators. All glass cockpit airplanes are sufficiently similar that the IMMI could be tailored to the mode management system of any modern cockpit. The IMMI does not replace the

    Full Text Available O autor parte da premissa de que a profilaxia da doença infecciosa decorre do encadeamento epidemiológico: fonte de infecção-veículo transmissor - receptivel, para explicar a da peste, baseada no mesmo princípio. Depois de citar os 4 principais complexos epidemiológicos da peste e afirmar que tôda a profilaxia da doença consiste em atingir os dois primeiros elos dessas cadeias e proteger o último, passa a classificar os vários métodos profiláticos empregados em 2 grandes grupos: o das medidas destrutivas ou provisórias e o das medidas supressivas ou definitivas. Entre as primeiras arrola a desratização e a despulização, às quais acrescenta o tratamento e isolamento do doente e do portaãor, e entre as segundas inclui a anti-ratização e a imunização. A seguir, passa a explicar em que consistem essas várias medidas profiláticas e quais os agentes de que se tem lançado mão para executá-las, expendendo ao curso dessa exposição o conceito que formula a respeito de cada uma delas, à guisa de apreciação do seu valor relativo. Enaltece sobretudo as medidas supressivas ou definitivas, às quais empresta a maior significação na luta antipestosa, chamando a atenção, em especial, para a necessidade de estudos imunológicos para aperfeiçoamento do poder imunitário das vacinas de germes vivos avirulentos, que considera um grande recurso para a profilaxia da doença, sobretudo para a proteção do rurícola, cujo labor e modo de vida o expõem inevitavelmente a se infectar, por ocasião da ocorrência de epizootias de origem silvestre. Concluída essa primeira parte, passa a fazer o histórico de como se desenvolveu a campanha contra a peste, no Brasil, desde a época da sua invasão em 1899 pelo pôrto de Santos até os nossos dias. Nesse histórico, detem-se um pouco para expôr a atuação do extinto Serviço Nacional de Peste, o qual, criado em 1941, após a reorganização do Departamento Nacional de Saúde, passou

  10. Command Interface ASIC - Analog Interface ASIC Chip Set

    2003-01-01

    A command interface application-specific integrated circuit (ASIC) and an analog interface ASIC have been developed as a chip set for remote actuation and monitoring of a collection of switches, which can be used to control generic loads, pyrotechnic devices, and valves in a high-radiation environment. The command interface ASIC (CIA) can be used alone or in combination with the analog interface ASIC (AIA). Designed primarily for incorporation into spacecraft control systems, they are also suitable for use in high-radiation terrestrial environments (e.g., in nuclear power plants and facilities that process radioactive materials). The primary role of the CIA within a spacecraft or other power system is to provide a reconfigurable means of regulating the power bus, actuating all valves, firing all pyrotechnic devices, and controlling the switching of power to all switchable loads. The CIA is a mixed-signal (analog and digital) ASIC that includes an embedded microcontroller with supporting fault-tolerant switch control and monitoring circuitry that is capable of connecting to a redundant set of interintegrated circuit (I(sup 2)C) buses. Commands and telemetry requests are communicated to the CIA. Adherence to the I(sup 2)C bus standard helps to reduce development costs by facilitating the use of previously developed, commercially available components. The AIA is a mixed-signal ASIC that includes the analog circuitry needed to connect the CIA to a custom higher powered version of the I(sup 2)C bus. The higher-powered version is designed to enable operation with bus cables longer than those contemplated in the I(sup 2)C standard. If there are multiple higher-power I(sup 2)C-like buses, then there must an AIA between the CIA and each such bus. The AIA includes two identical interface blocks: one for the side-A I(sup 2)C clock and data buses and the other for the side B buses. All the AIAs on each side are powered from a common power converter module (PCM). Sides A and B

  12. Soft matter at aqueous interfaces

    CERN Document Server

    Liu, Yi

    2016-01-01

    This book covers the science of interfaces between an aqueous phase and a solid, another liquid or a gaseous phase, starting from the basic physical chemistry all the way to state-of-the-art research developments. Both experimental and theoretical methods are treated thanks to the contributions of a distinguished list of authors who are all active researchers in their respective fields. The properties of these interfaces are crucial for a wide variety of processes, products and biological systems and functions, such as the formulation of personal care and food products, paints and coatings, microfluidic and lab-on-a-chip applications, cell membranes, and lung surfactants. Accordingly, research and expertise on the subject are spread over a broad range of academic disciplines and industrial laboratories. This book brings together knowledge from these different places with the aim of fostering education, collaborations and research progress.

  13. Interfaces in ceramic nuclear fuels

    International Nuclear Information System (INIS)

    Reeve, K.D.

    Internal interfaces in all-ceramic dispersion fuels (such as these for HTGRs) are discussed for two classes: BeO-based dispersions, and coated particles for graphite-based fuels. The following points are made: (1) The strength of a two-phase dispersion is controlled by the weaker dispersed phase bonded to the matrix. (2) Differential expansion between two phases can be controlled by an intermediate buffer zone of low density. (3) A thin ceramic coating should be in compression. (4) Chemical reaction between coating and substrate and mass transfer in service should be minimized. The problems of the nuclear fuel designer are to develop coatings for fission product retention, and to produce radiation-resistant interfaces. 44 references, 18 figures

    In the development of and discourses around interfaces there has always been a strong urge to bypass representation and ‘jack’ directly in to the human brain, consciousness, perceptions and feelings. In her article ”The interface at the skin” Lone Koefoed Hansen looks at how two contemporary...... experimental dresses made by Philips within the field of wearable computing subscribe to the concept of ‘ideal communication’. In her article, she explains how this particular type of communication is linked to the paranormal phenomena of mind reading and telepathy, and argues that sensor-based wearable...... computing is the newest example of a technological development implicitly or explicitly aiming at manifesting two utopian parameters of communication: immediacy and instantaneity. Though utopian, this manifestation has served as a way to brand Philips “as a highly innovative and remarkable company”....

  15. Towards personalized adaptive user interfaces

    Kostov, Vlaho; Fukuda, Shuchi; Yanagisawa, Hideyoshi

    2002-01-01

    An approach towards standardization of the general rules for synthesis and design of man machine interfaces that include dynamic adaptive behavior is presented. The link between the personality type (Myers-Briggs or Kersey Temperament sorter) and the personal preferences of the users (Kansei) for the purpose of building Graphical User Interface (GU]) was investigated. The rules for a personalized el-notional GUI based on the subjective preferences of the users were defined. The results were tested on a modified TETRIS game that displayed background characters capable of emotional response. When the system responded to a user in a manner that is customized to his or her preferences, the reaction time was smaller and the information transfer was faster. Usability testing methods were used and it was shown that development of pleasant cartoon face GUI based on the users inborn personality tendencies was feasible. (Author)

    Our research program on Ultrafast Thermal Transport at Interfaces advanced understanding of the mesoscale science of heat conduction. At the length and time scales of atoms and atomic motions, energy is transported by interactions between single-particle and collective excitations. At macroscopic scales, entropy, temperature, and heat are the governing concepts. Key gaps in fundamental knowledge appear at the transitions between these two regimes. The transport of thermal energy at interfaces plays a pivotal role in these scientific issues. Measurements of heat transport with ultrafast time resolution are needed because picoseconds are the fundamental scales where the lack of equilibrium between various thermal excitations becomes a important factor in the transport physics. A critical aspect of our work has been the development of experimental methods and model systems that enabled more precise and sensitive investigations of nanoscale thermal transport.

    1983-01-01

    A typical high energy physics experiment requires both a high speed data acquisition and processing system, for data collection and reduction; and a general purpose computer to handle further reduction, bookkeeping and mass storage. Broad differences in architecture, format or technology, will often exist between these two systems, and interface design can become a formidable task. The PDP-11 series minicomputer is widely used in physics research, and the Brookhaven FASTBUS is the only standard high speed data acquisition system which is fully implemented in a current high energy physics experiment. This paper will describe the design and operation of an interface between these two systems. The major issues are elucidated by a preliminary discussion on the basic principles of Bus Systems, and their application to Brookhaven FASTBUS and UNIBUS

    Andreassen, Hege Kristin; Lundvoll Nilsen, Line

    2013-01-01

    Increased patient involvement is a goal in contemporary health care, and of importance to the development of patient oriented ICT. In this paper we discuss how the design of patient-user interfaces can affect patient involvement. Our discussion is based on 12 semi-structured interviews with patient users of a web-based solution for patient--doctor communication piloted in Norway. We argue ICT solutions offering a choice of user interfaces on the patient side are preferable to ensure individual accommodation and a high degree of patient involvement. When introducing web-based tools for patient--health professional communication a free-text option should be provided to the patient users.

  19. Low latency asynchronous interface circuits

    Sadowski, Greg

    2017-06-20

    In one form, a logic circuit includes an asynchronous logic circuit, a synchronous logic circuit, and an interface circuit coupled between the asynchronous logic circuit and the synchronous logic circuit. The asynchronous logic circuit has a plurality of asynchronous outputs for providing a corresponding plurality of asynchronous signals. The synchronous logic circuit has a plurality of synchronous inputs corresponding to the plurality of asynchronous outputs, a stretch input for receiving a stretch signal, and a clock output for providing a clock signal. The synchronous logic circuit provides the clock signal as a periodic signal but prolongs a predetermined state of the clock signal while the stretch signal is active. The asynchronous interface detects whether metastability could occur when latching any of the plurality of the asynchronous outputs of the asynchronous logic circuit using said clock signal, and activates the stretch signal while the metastability could occur.

If it were possible to touch, see, or measure software, it would be easier to analyze and prove its quality. Unfortunately, software is an intangible asset, which makes testing complex. This is especially true when software quality is not a question of particular functions that can be tested through a graphical user interface. The primary objective of softwar...

    A brief introduction to the basic auditory abilities of the human perceiver with particular attention toward issues that may be important for the design of auditory interfaces is presented. The importance of appropriate auditory inputs to observers with normal hearing is probably related to the role of hearing as an omnidirectional, early warning system and to its role as the primary vehicle for communication of strong personal feelings.

    The CSCview data mining interface is available for browsing the Chandra Source Catalog (CSC) and downloading tables of quality-assured source properties and data products. Once the desired source properties and search criteria are entered into the CSCview query form, the resulting source matches are returned in a table along with the values of the requested source properties for each source. (The catalog can be searched on any source property, not just position.) At this point, the table of search results may be saved to a text file, and the available data products for each source may be downloaded. CSCview save files are output in RDB-like and VOTable format. The available CSC data products include event files, spectra, lightcurves, and images, all of which are processed with the CIAO software. CSC data may also be accessed non-interactively with Unix command-line tools such as cURL and Wget, using ADQL 2.0 query syntax. In fact, CSCview features a separate ADQL query form for those who wish to specify this type of query within the GUI. Several interfaces are available for learning if a source is included in the catalog (in addition to CSCview): 1) the CSC interface to Sky in Google Earth shows the footprint of each Chandra observation on the sky, along with the CSC footprint for comparison (CSC source properties are also accessible when a source within a Chandra field-of-view is clicked); 2) the CSC Limiting Sensitivity online tool indicates if a source at an input celestial location was too faint for detection; 3) an IVOA Simple Cone Search interface locates all CSC sources within a specified radius of an R.A. and Dec.; and 4) the CSC-SDSS cross-match service returns the list of sources common to the CSC and SDSS, either all such sources or a subset based on search criteria.

  9. The Interface Theory of Perception.

    Hoffman, Donald D; Singh, Manish; Prakash, Chetan

    2015-12-01

    Perception is a product of evolution. Our perceptual systems, like our limbs and livers, have been shaped by natural selection. The effects of selection on perception can be studied using evolutionary games and genetic algorithms. To this end, we define and classify perceptual strategies and allow them to compete in evolutionary games in a variety of worlds with a variety of fitness functions. We find that veridical perceptions--strategies tuned to the true structure of the world--are routinely dominated by nonveridical strategies tuned to fitness. Veridical perceptions escape extinction only if fitness varies monotonically with truth. Thus, a perceptual strategy favored by selection is best thought of not as a window on truth but as akin to a windows interface of a PC. Just as the color and shape of an icon for a text file do not entail that the text file itself has a color or shape, so also our perceptions of space-time and objects do not entail (by the Invention of Space-Time Theorem) that objective reality has the structure of space-time and objects. An interface serves to guide useful actions, not to resemble truth. Indeed, an interface hides the truth; for someone editing a paper or photo, seeing transistors and firmware is an irrelevant hindrance. For the perceptions of H. sapiens, space-time is the desktop and physical objects are the icons. Our perceptions of space-time and objects have been shaped by natural selection to hide the truth and guide adaptive behaviors. Perception is an adaptive interface.

    Handheld technology finds slowly its place in the healthcare world. Some clinicians already use intensively dedicated mobile applications to consult clinical references. However, handheld technology hasn't still broadly embraced to the core of the healthcare business, the hospitals. The weak penetration of handheld technology in the hospitals can be partly explained by the caution of stakeholders that must be convinced about the efficiency of these tools before going forward. In a domain where temporal constraints are increasingly strong, caregivers cannot loose time on playing with gadgets. All users are not comfortable with tactile manipulations and the lack of dedicated peripheral complicates entering data for novices. Stakeholders must be convinced that caregivers will be able to master handheld devices. In this paper, we make the assumption that the proper design of an interface may influence users' performances to record information. We are also interested to find out whether users increase their efficiency when using handheld tools repeatedly. To answer these questions, we have set up a field study to compare users' performances on three different user interfaces while recording vital signs. Some user interfaces were familiar to users, and others were totally innovative. Results showed that users' familiarity with smartphone influences their performances and that users improve their performances by repeating a task.

    2017-11-01

    Bubble bursting is crucial to understanding the life span of bubbles at an interface and more importantly the nature of interaction between the bulk liquid and the outside environment from the point of view of chemical and biological material transport. The dynamics of the bubble as it rises from inside the liquid bulk to its disappearance on the interface after bursting is an intriguing process, many aspects of which are still being explored. In our study, we make detailed high speed imaging measurements to examine carefully the hole initiation and growth in bursting bubbles that unearth some interesting features of the process. Previous analyses available in literature are revisited based on our novel experimental visualizations. Using a combination of experiments and theory we investigate the role of various forces during the rupturing process. This work aims to further our current knowledge of bubble dynamics at an interface with an aim of predicting better the bubble evolution from its growth to its eventual integration with the liquid bulk.

    2015-01-02

    © 2014 American Chemical Society. Much is known about the rate of photoexcited charge generation in at organic donor/acceptor (D/A) heterojunctions overaged over all relative arrangements. However, there has been very little experimental work investigating how the photoexcited electron transfer (ET) rate depends on the precise relative molecular orientation between D and A in thin solid films. This is the question that we address in this work. We find that the ET rate depends strongly on the relative molecular arrangement: The interface where the model donor compound copper phthalocyanine is oriented face-on with respect to the fullerene C60 acceptor yields a rate that is approximately 4 times faster than that of the edge-on oriented interface. Our results suggest that the D/A electronic coupling is significantly enhanced in the face-on case, which agrees well with theoretical predictions, underscoring the importance of controlling the relative interfacial molecular orientation.

Pretendo com isso demarcar fricções entre o design das interfaces gráficas de estéticas ruidosas e os constructos audiovisuais dos games, em uma relação ambivalente entre apagamento e permanência dos rastros da cultura audiovisual nestas superfícies. Busco, através disso, realizar uma angulação teórica entre a estética do ruído conforme proposta por Giselle Beiguelman, a abordagem de Alexander Galloway sobre art game mods, as interfaces culturais de que fala Lev Manovich e a pesquisa crítica e especulativa em software studies de Matthew Fuller, para discutir potências resultantes da interação entre estas perspectivas que compõem parte do tecido da tecnocultura contemporânea. Assim, a partir da comunicação audiovisual, mas explorando os limiares desta com o design de interface dos games, sugiro iniciar um debate passível de ampliação em discussões vindouras análogas ao tema.

The needs of ATLAS global computing imposed challenging requirements on the design of PanDA in areas such as scalability, robustness, automation, diagnostics, and usability for both production shifters and analysis users. Through a system-wide job database, the PanDA monitor provides a comprehensive and coherent view of the system and job execution, from high level summaries to detailed drill-down job diagnostics. It is (like the rest of PanDA) an Apache-based Python application backed by Oracle. The presentation layer is HTML code generated on the fly in the Python application which is also responsible for managing database queries. However, this approach is lacking in user interface flexibility, simplicity of communication with external systems, and ease of maintenance. A decision was therefore made to migrate the PanDA monitor server to Django Web Application Framework and apply JSON/AJAX technology in the browser front end. This allows us to greatly reduce the amount of application code, separate data preparation from presentation, leverage open source for tools such as authentication and authorization mechanisms, and provide a richer and more dynamic user experience. We describe our approach, design and initial experience with the migration process.

  8. Interface recombination influence on carrier transport

    International Nuclear Information System (INIS)

    Konin, A

    2013-01-01

    A theory of interface recombination in the semiconductor–semiconductor junction is developed. The interface recombination rate dependence on the nonequilibrium carrier densities is derived on the basis of a model in which the interface recombination occurs through the mechanism of trapping. The general relation between the interface recombination parameters at small carrier density deviation from the equilibrium ones is obtained. The validity of this relation is proved considering the generation of the Hall electric field in the extrinsic semiconductor sample. The anomalous Hall electromotive force in a weak magnetic field was investigated and interpreted by means of a new interface recombination model. The experimental data corroborate the developed theory. (paper)

  9. Roles and Delegation of Authority (R/DA) System; TOPICAL

    1999-01-01

    The processes of defining managerial roles and providing for delegation of authority are essential to any enterprise. At most large organizations, these processes are defined in policy manuals and through sets of standard operating procedures for many, if not all, business and administrative functions. Many of these staff-initiated, administrative functions require the routing of documents for approval to one or more levels of management. These employee-oriented, back office types of workflows tend to require more flexibility in determining to whom these documents should go to, while, at the same time, providing the responsible parties with the flexibility to delegate their approval authority or allow others to review their work. Although this practice is commonplace in manual, paper-based processes that exist in many organizations, it is difficult to provide the same flexibility in the more structured, electronic-based, workflow systems. The purpose of this report is to present a framework or architecture for creating a R/DA system and provide some insights associated with its design and utilization. To improve understanding and clarify subsequent discussion, the goals and requirements for the major R/DA system components, namely, the database and interface modules, are initially presented along with the identification of important concepts and the definition of critical terms. Next high-level functions relating the types of inputs to the outputs of the R/DA interface module are introduced and discussed. Then the relationships between the major R/DA modules and the primary components associated with its creation and maintenance are presented and analyzed. Finally, some conclusions are drawn relative to the advantages associated with developing a R/DA system for use in implementing an enterprise-wide, work-facilitating information system

    We have developed a mature laboratory at Sandia to measure interfacial rheology, using a combination of home-built, commercially available, and customized commercial tools. An Interfacial Shear Rheometer (KSV ISR-400) was modified and the software improved to increase sensitivity and reliability. Another shear rheometer, a TA Instruments AR-G2, was equipped with a du Nouey ring, bicone geometry, and a double wall ring. These interfacial attachments were compared to each other and to the ISR. The best results with the AR-G2 were obtained with the du Nouey ring. A Micro-Interfacial Rheometer (MIR) was developed in house to obtain the much higher sensitivity given by a smaller probe. However, it was found to be difficult to apply this technique for highly elastic surfaces. Interfaces also exhibit dilatational rheology when the interface changes area, such as occurs when bubbles grow or shrink. To measure this rheological response we developed a Surface Dilatational Rheometer (SDR), in which changes in surface tension with surface area are measured during the oscillation of the volume of a pendant drop or bubble. All instruments were tested with various surfactant solutions to determine the limitations of each. In addition, foaming capability and foam stability were tested and compared with the rheology data. It was found that there was no clear correlation of surface rheology with foaming/defoaming with different types of surfactants, but, within a family of surfactants, rheology could predict the foam stability. Diffusion of surfactants to the interface and the behavior of polyelectrolytes were two subjects studied with the new equipment. Finally, surface rheological terms were added to a finite element Navier-Stokes solver and preliminary testing of the code completed. Recommendations for improved implementation were given. When completed we plan to use the computations to better interpret the experimental data and account for the effects of the underlying bulk

Retoma-se essa causa que acompanha a história da Igreja desde os seus primórdios e que interessa a todos os membros do povo santo de Deus. O texto divide-se em quatro partes. Primeiro, faz-se um apanhado histórico dos anseios de reforma da Igreja, mostrando que, muitas vezes em instâncias subterrâneas, sempre houve o desejo e também ações concretas de renovação. Em seguida, apresenta-se como razão para a reforma da Igreja o anúncio e a realização do Reino de Deus, pelo qual é preciso que a Igreja se volte à concretude humana e histórica de Jesus de Nazaré, pela superação do apego ao poder e às estruturas religiosas. Num terceiro momento, trata-se do critério pelo qual se mede a realização e a veracidade da reforma da Igreja: a santidade de cada fiel e do povo cristão no meio do mundo. Por fim, conclui-se que o caminho para a reforma da Igreja está na escuta dos clamores do Espírito Santo, que fala na própria Igreja e no mundo através do sensus fidei dos fiéis, das Igrejas particulares, dos pobres, das mulheres e das realidades terrestres.

    We analyze two intertwined and fundamental issues concerning computer-to-human communication in the multimodal interfaces: the interplay between sound and graphics, and the role of object persistence. Our observations lead us to introduce metawidgets as abstract entities capable of manifesting themselves to users as image, as sound, or as various combinations and/or sequences of the two media. We show examples of metawidgets in action, and discuss mechanisms for choosing among alternative media for metawidget instantiation. Finally, we describe a couple of experimental microworlds we have implemented to test out some of our ideas. 17 refs., 7 figs.

    The da Vinci surgical system was developed by Intuitive Surgical Inc. in the United States as an endoscopic surgical device to assist remote control surgeries. In 1998, the Da Vinci system was first used for cardiothoracic procedures. Currently a combination of robot-assisted internal thoracic artery harvest together with coronary artery bypass grafting (CABG) through a mini-incision (ThoraCAB) or totally endoscopic procedures including anastomoses under robotic assistance (TECAB) are being conducted for the treatment of coronary artery diseases. With the recent advances in catheter interventions, hybrid procedures combining catheter intervention with ThoraCAB or TECAB are anticipated in the future.On the other hand, with the decrease in number of coronary artery bypass surgeries, the share of valvular surgeries is expected to increase in the future. Among them, mitral valvuloplasty for mitral regurgitation is anticipated to be conducted mainly by low-invasive procedures, represented by minimally invasive cardiac surgery( MICS) and robot-assisted surgery. Apart from the intrinsic good surgical view, robotic-assisted systems offer additional advantages of the availability of an amplified view and the easy to observe the mitral valve in the physiological position. Thus, robotic surgical surgeries that make complicated procedures easier are expected to accomplish further developments in the future. Furthermore, while the number of surgeries for atrial septal defects has decreased dramatically following the widespread use of Amplatzer septal occluder, robotic surgery may become a good indication for cases in which the Amplatzer device is not indicated. In Japan, clinical trial of the da Vinci robotic system for heart surgeries has been completed. Statutory approval of the da Vinci system for mitral regurgitation and atrial septal defects is anticipated in the next few years.

É quando o processo identitário expressa crises reais ou virtuais, como as que têm lugar entre imigrantes latino-americanos nos Estados Unidos, entre povos de diferentes regiões da Espanha emigrados para Barcelona, entre catalães espanhóis, franceses e andorranos residentes em Andorra, e entre povos indígenas em regiões de fronteira do Brasil com países vizinhos. O exame do processo identitário que tem lugar em diferentes latitudes, nas Américas e na Europa, sugere que os fenômenos socioculturais de etnicidade e de nacionalidade possuem em comum características tais como a busca de reconhecimento da pessoa moral, o respeito à diferença e, como corolário ético, a elevação do que se pode definir como "taxa de consideração".

    Full Text Available Constitui interesse emergente em saúde pública avaliar a possibilidade de intoxicação humana por biotoxinas de algas cianofíceas, principalmente as hepatotoxinas do grupo das microcistinas. A microcistina, um heptapeptídeo monocíclico, é produzida principalmente pela cianobactéria Microcistis aeruginosa. São caracterizadas por alguns aminoácidos variáveis, dois deles com uma estrutura não usual que possuem importante papel na hepatotoxidade da microcistina. Apesar do acometimento humano atribuído as microcistinas incluírem gastroenterite, reações alérgicas ou irritativas, neurotoxicidade, o principal alvo da toxina é o fígado. Nos hepatócitos as microcistinas são carreadas pelo sistema transportador do ácido biliar, inibindo a atividade da proteína fosfatase no citoplasma. A inibição leva a mudanças morfológicas na membrana plasmática pela hiperfosforilação de citoqueratinas, e à atividade de promoção tumoral pelas proteínas hiperfosforiladas. Os métodos de detecção e quantificação de microcistinas no ambiente incluem a cromatografia líquida, o bioensaio em camundongos e os testes imunoenzimáticos. O último vem ganhando destaque pela praticidade e alta sensibilidade.

    Full Text Available A brain-computer interface (BCI is a hardware and software communications system that permits cerebral activity alone to control computers or external devices. The immediate goal of BCI research is to provide communications capabilities to severely disabled people who are totally paralyzed or ‘locked in’ by neurological neuromuscular disorders, such as amyotrophic lateral sclerosis, brain stem stroke, or spinal cord injury. Here, we review the state-of-the-art of BCIs, looking at the different steps that form a standard BCI: signal acquisition, preprocessing or signal enhancement, feature extraction, classification and the control interface. We discuss their advantages, drawbacks, and latest advances, and we survey the numerous technologies reported in the scientific literature to design each step of a BCI. First, the review examines the neuroimaging modalities used in the signal acquisition step, each of which monitors a different functional brain activity such as electrical, magnetic or metabolic activity. Second, the review discusses different electrophysiological control signals that determine user intentions, which can be detected in brain activity. Third, the review includes some techniques used in the signal enhancement step to deal with the artifacts in the control signals and improve the performance. Fourth, the review studies some mathematic algorithms used in the feature extraction and classification steps which translate the information in the control signals into commands that operate a computer or other device. Finally, the review provides an overview of various BCI applications that control a range of devices.

    Gwilt, Ian

    This essay discusses the use of the Graphical User Interface (GUI) as a site of creative practice. By creatively repositioning the GUI as a work of art it is possible to challenge our understanding and expectations of the conventional computer interface wherein the icons and navigational architecture of the GUI no longer function as a technological tool. These artistic recontextualizations are often used to question our engagement with technology and to highlight the pivotal place that the domestic computer has taken in our everyday social, cultural and (increasingly), creative domains. Through these works the media specificity of the screen-based GUI can broken by dramatic changes in scale, form and configuration. This can be seen through the work of new media artists who have re-imagined the GUI in a number of creative forms both, within the digital, as image, animation, net and interactive art, and in the analogue, as print, painting, sculpture, installation and performative event. Furthermore as a creative work, the GUI can also be utilized as a visual way-finder to explore the relationship between the dynamic potentials of the digital and the concretized qualities of the material artifact.

    This interface permits the testing of high speed semiconductor devices (room-temperature chips) by a Josephson junction sampling device (cryogenic chip) without intolerable loss of resolution. The interface comprises a quartz pass-through plug which includes a planar transmission line interconnecting a first chip station, where the cryogenic chip is mounted, and a second chip station, where the semiconductor chip to be tested is temporarily mounted. The pass-through plug has a cemented long half-cylindrical portion and short half-cylindrical portion. The long portion carries the planar transmission line, the ends of which form the first and second chip mounting stations. The short portion completes the cylinder with the long portion for part of its length, where a seal can be achieved, but does not extend over the chip mounting stations. Sealing is by epoxy cement. The pass-through plug is sealed in place in a flange mounted to the chamber wall. The first chip station, with the cryogenic chip attached, extends into the liquid helium reservoir. The second chip station is in the room temperature environment required for semiconductor operation. Proper semiconductor operating temperature is achieved by a heater wire and control thermocouple in the vicinity of each other and the second chip mounting station. Thermal isolation is maintained by vacuum and seals. Connections for power and control, for test result signals, for temperature control and heating, and for vacuum complete the test apparatus

    Full Text Available Software quality is determined by assessing the characteristics that specify how it should work, which are verified through testing. If it were possible to touch, see, or measure software, it would be easier to analyze and prove its quality. Unfortunately, software is an intangible asset, which makes testing complex. This is especially true when software quality is not a question of particular functions that can be tested through a graphical user interface. The primary objective of software architecture is to design quality of software through modeling and visualization. There are many methods and standards that define how to control and manage quality. However, many IT software development projects still fail due to the difficulties involved in measuring, controlling, and managing software quality. Software quality failure factors are numerous. Examples include beginning to test software too late in the development process, or failing properly to understand, or design, the software architecture and the software component structure. The goal of this article is to provide an interface-based software testing technique that better measures software quality, automates software quality testing, encourages early testing, and increases the software’s overall testability

    Full Text Available Enterprise architecture frameworks define the goals of enterprise architecture in order to make business processes and IT operations more effective, and to reduce the risk of future investments. These enterprise architecture frameworks offer different architecture development methods that help in building enterprise architecture. In practice, the larger organizations become, the larger their enterprise architecture and IT become. This leads to an increasingly complex system of enterprise architecture development and maintenance. Application software architecture is one type of architecture that, along with business architecture, data architecture and technology architecture, composes enterprise architecture. From the perspective of integration, enterprise architecture can be considered a system of interaction between multiple examples of application software. Therefore, effective software integration is a very important basis for the future success of the enterprise architecture in question. This article will provide interface-based integration practice in order to help simplify the process of building such a software integration system. The main goal of interface-based software integration is to solve problems that may arise with software integration requirements and developing software integration architecture.

    The requirements of tritium technology are centered in three main areas, (1) fuel processing, (2) breeder tritium extraction, and (3) tritium containment. The Tritium Systems Test Assembly (TSTA) now in operation at Los Alamos National Laboratory (LANL) is dedicated to developing and demonstrating the tritium technology for fuel processing and containment. TSTA is the only fusion fuel processing facility that can operate in a continuous closed-loop mode. The tritium throughput of TSTA is 1000 g/d. However, TSTA does not have a blanket interface system. The authors have initiated a study to define a Breeder Blanket Interface (BBIO) for TSTA. The first step of the work is to define the condition of the gaseous tritium stream from the blanket tritium recovery system. This report summarizes this part of the work for one particular blanket concept, i.e., a self-cooled lithium blanket. The total gas throughput, the hydrogen to tritium ratio, the corrosive chemicals, and the radionuclides are defined. Various methods of tritium recovery from liquid lithium were assessed: yttrium gettering, permeation windows, and molten salt extraction. The authors' evaluation concluded that the best method was molten salt extraction

    The failure of frictional interfaces and the spatiotemporal structures that accompany it are central to a wide range of geophysical, physical and engineering systems. Recent geophysical and laboratory observations indicated that interfacial failure can be mediated by slow slip rupture phenomena which are distinct from ordinary, earthquake-like, fast rupture. These discoveries have influenced the way we think about frictional motion, yet the nature and properties of slow rupture are not completely understood. We show that slow rupture is an intrinsic and robust property of simple non-monotonic rate-and-state friction laws. It is associated with a new velocity scale cmin, determined by the friction law, below which steady state rupture cannot propagate. We further show that rupture can occur in a continuum of states, spanning a wide range of velocities from cmin to elastic wave-speeds, and predict different properties for slow rupture and ordinary fast rupture. Our results are qualitatively consistent with recent high-resolution laboratory experiments and may provide a theoretical framework for understanding slow rupture phenomena along frictional interfaces.

    Evander, Mikael; Tenje, Maria

    2014-01-01

    We present the design and fabrication of a polymeric capillary fluidic interface fabricated by micro-milling. The design enables the use of glass capillaries with any kind of cross-section in complex microfluidic setups. We demonstrate two different designs of the interface; a double-inlet interface for hydrodynamic focusing and a capillary interface with integrated pneumatic valves. Both capillary interfaces are presented together with examples of practical applications. This communication shows the design optimization and presents details of the fabrication process. The capillary interface opens up for the use of complex microfluidic systems in single-use glass capillaries. They also enable simple fabrication of glass/polymer hybrid devices that can be beneficial in many research fields where a pure polymer chip negatively affects the device's performance, e.g. acoustofluidics.

  17. Interface management for the Yucca Mountain Project

    International Nuclear Information System (INIS)

    1988-12-01

    The subject of this report is selection of that portion of physical and informational interfaces that need to be controlled on the Yucca Mountain Project (YMP). Physical interfaces are interactions between physical elements of the mined geologic disposal system; for example, the repository shafts will interface with the shafts in the Exploratory Shaft Facility (ESF), because the ESF shafts will eventually be absorbed into the repository as additional repository shafts. Informational interfaces are interactions involving an exchange of information between organizations working on the mined geologic disposal system; for example, the in situ testing contractor will interact with the site performance assessment contractor and will supply information regarding host rock behavior. This report describes the physical system interfaces that can be identified from analysis of a physical system structure. A discussion of informational interfaces can be found elsewhere. 30 refs., 8 figs., 3 tabs

  18. Kinetics of protein unfolding at interfaces

    International Nuclear Information System (INIS)

    Yano, Yohko F

    2012-01-01

    The conformation of protein molecules is determined by a balance of various forces, including van der Waals attraction, electrostatic interaction, hydrogen bonding, and conformational entropy. When protein molecules encounter an interface, they are often adsorbed on the interface. The conformation of an adsorbed protein molecule strongly depends on the interaction between the protein and the interface. Recent time-resolved investigations have revealed that protein conformation changes during the adsorption process due to the protein-protein interaction increasing with increasing interface coverage. External conditions also affect the protein conformation. This review considers recent dynamic observations of protein adsorption at various interfaces and their implications for the kinetics of protein unfolding at interfaces. (topical review)

    The application of topology in optics has led to a new paradigm in developing photonic devices with robust properties against disorder. Although considerable progress on topological phenomena has been achieved in the classical domain, the realization of strong light-matter coupling in the quantum domain remains unexplored. We demonstrate a strong interface between single quantum emitters and topological photonic states. Our approach creates robust counterpropagating edge states at the boundary of two distinct topological photonic crystals. We demonstrate the chiral emission of a quantum emitter into these modes and establish their robustness against sharp bends. This approach may enable the development of quantum optics devices with built-in protection, with potential applications in quantum simulation and sensing.

    Salez, Thomas; Salez, Justin; Dalnoki-Veress, Kari; Raphaël, Elie; Forrest, James A

    2015-07-07

    We introduce a minimal theory of glass formation based on the ideas of molecular crowding and resultant string-like cooperative rearrangement, and address the effects of free interfaces. In the bulk case, we obtain a scaling expression for the number of particles taking part in cooperative strings, and we recover the Adam-Gibbs description of glassy dynamics. Then, by including thermal dilatation, the Vogel-Fulcher-Tammann relation is derived. Moreover, the random and string-like characters of the cooperative rearrangement allow us to predict a temperature-dependent expression for the cooperative length ξ of bulk relaxation. Finally, we explore the influence of sample boundaries when the system size becomes comparable to ξ. The theory is in agreement with measurements of the glass-transition temperature of thin polymer films, and allows quantification of the temperature-dependent thickness hm of the interfacial mobile layer.

    2011-01-01

    Ionic liquids have attracted considerable interest in recent years. In this book the bulk and interfacial physico-chemical characteristics of various fluid systems dominated by Coulomb interactions are treated which includes molten salts, ionic liquids as well as metal-molten salt mixtures and expanded fluid metals. Of particular interest is the comparison of the different systems. Topics in the bulk phase concern the microscopic structure, the phase behaviour and critical phenomena, and the metal-nonmetal transition. Interfacial phenomena include wetting transitions, electrowetting, surface freezing, and the electrified ionic liquid/ electrode interface. With regard to the latter 2D and 3D electrochemical phase formation of metals and semi-conductors on the nanometer scale is described for a number of selected examples. The basic concepts and various experimental methods are introduced making the book suitable for both graduate students and researchers interested in Coulombic fluids.

    This paper reports that at the solidification velocities observed during pulsed laser annealing, the planar interface between solid and liquid is stabilized by capillarity and nonequilibrium effects such as solute trapping. The authors used Rutherford backscattering and electron microscopy to determine the nonequilibrium partition coefficient and critical concentration for breakdown of the planar interface as a function of interface velocity for Sn-implanted silicon. This allows the authors to test the applicability of the Mulliins-Sekerka stability theory to interfaces not in local equilibrium and to test the Coriell-Sekerka and other theories for oscillatory instabilities

  17. An interface energy density-based theory considering the coherent interface effect in nanomaterials

    Science.gov (United States)

    Yao, Yin; Chen, Shaohua; Fang, Daining

    2017-02-01

    To characterize the coherent interface effect conveniently and feasibly in nanomaterials, a continuum theory is proposed that is based on the concept of the interface free energy density, which is a dominant factor affecting the mechanical properties of the coherent interface in materials of all scales. The effect of the residual strain caused by self-relaxation and the lattice misfit of nanomaterials, as well as that due to the interface deformation induced by an external load on the interface free energy density is considered. In contrast to the existing theories, the stress discontinuity at the interface is characterized by the interface free energy density through an interface-induced traction. As a result, the interface elastic constant introduced in previous theories, which is not easy to determine precisely, is avoided in the present theory. Only the surface energy density of the bulk materials forming the interface, the relaxation parameter induced by surface relaxation, and the mismatch parameter for forming a coherent interface between the two surfaces are involved. All the related parameters are far easier to determine than the interface elastic constants. The effective bulk and shear moduli of a nanoparticle-reinforced nanocomposite are predicted using the proposed theory. Closed-form solutions are achieved, demonstrating the feasibility and convenience of the proposed model for predicting the interface effect in nanomaterials.

    Full Text Available Resumo Ao discorrer sobre o “Futuro do Etnocentrismo”, este artigo parte da premissa de que a globalização, apesar de ter – em muitos casos – diminuído as diferenças entre povos, não tem amenizado os preconceitos e as formas de discriminação que ocorrem em nome dessas diferenças. Ele resgata a importância do antropólogo neste cenário lembrando que a diversidade cultural faz parte da sociedade complexa, remetendo-se não apenas a grupos étnicos ou nacionais bem delimitados, mas também a diferenças de geração, gênero, sexo e classe, entre outros. Neste contexto, a tolerância passiva de modos distantes de vida assim como a aceitação pragmática de nosso próprio paroquialismo são atitudes não somente intelectualmente desonestas mas também moralmente repreensíveis. É no encontro incômodo de subjetividades variantes na sua própria sociedade que o antropólogo define seu lugar.

Para tal concorreram a investigação (engenharia biomédica, a evolução técnica e a diferenciação clínica de diferentes especialidades. Para que esta evolução se transfira para o paciente com o seu máximo potencial, o diálogo e a interdisciplinaridade são imprescindíveis. Nesta Edição da Gazeta Médica, vários artigos trazem até ao leitor alguns exemplos desta evolução e interdisciplinaridade, que continua todos os dias nos nossos hospitais. Assim não podemos deixar de salientar o enorme progresso que houve no desenvolvimento de antimicrobianos e logicamente, o desafio que agora enfrentamos, o da resistência aos antibióticos. Por outro lado, a biologia molecular ao permitir-nos conhecer melhor a origem e fisiopatologia de inúmeras doenças, abriu um janela de oportunidade para individualizar o algoritmo clínico de orientação e tratamento clínicos. É com naturalidade, portanto, que a seguir encontramos vários artigos que relatam estratégias de individualização terapêutica, aumentando o efeito terapêutico, e minimizando os efeitos laterais. Sendo o relator deste editorial, um cirurgião, não posso deixar de dar enfoque à forma como a cirurgia minimamente invasiva tem revolucionado a intervenção cirúrgica. A história reporta-nos que foram os urologistas e os ginecologistas os pioneiros em muitos dos passos determinantes para chegarmos à cirurgia laparoscópica.

Important levels of kinetic energy are already present in the irrotational region near the T/NT interface. The mean pressure and kinetic energy are well described by the Bernoulli equation in this region and agree with recent results obtained from rapid distortion theory in the turbulent region [M. A. C. Teixeira and C. B. da Silva, "Turbulence dynamics near a turbulent/non-turbulent interface," J. Fluid Mech. 695, 257-287 (2012)], 10.1017/jfm.2012.17 while the normal Reynolds stresses agree with the theoretical predictions from Phillips ["The irrotational motion outside a free turbulent boundary," Proc. Cambridge Philos. Soc. 51, 220 (1955)], 10.1017/S0305004100030073. The use of conditional statistics in relation to the distance from the T/NT interface allow a detailed study of the build up of kinetic energy across the T/NT interface, pointing to a very different picture than using classical statistics. Conditional kinetic energy budgets show that apart from the viscous dissipation of kinetic energy, the maximum of all the mechanisms governing the kinetic energy are concentrated in a very narrow region distancing about one to two Taylor micro-scales from the T/NT interface. The (total and fluctuating) kinetic energy starts increasing in the irrotational region by pressure-velocity interactions - a mechanism that can act at distance, and continue to grow by advection (for the total kinetic energy) and turbulent diffusion (for the turbulent kinetic energy) inside the turbulent region. These mechanisms tend to occur preferentially around the core of the large-scale vortices existing near T/NT interface. The production of turbulent

    Bonnell, D.; Ruehle, M.; Chowdhry, U.

    1995-01-01

    The motivation for the symposium was the observation that interfaces in crystallographically and compositionally complex systems often dictate the performance and reliability of devices that utilize functional ceramics. The current level of understanding of interface-property relations in silicon-based devices required over 30 years of intensive research. Similar issues influence the relationship between atomic bonding at interfaces and properties in functional ceramic systems. The current understanding of these complex interfaces does not allow correlation between atomic structure and interface properties, in spite of their importance to a number of emerging technologies (wireless communications, radar-based positioning systems, sensors, etc.). The objective of this symposium was to focus attention on these fundamental issues by featuring recent theoretical and experimental work from various disciplines that impact the understanding of interface chemistry, structure, and properties. The emphasis was on relating properties of surfaces and interfaces to structure through an understanding of atomic level phenomena. Interfaces of interest include metal/ceramic, ceramic/ceramic, ceramic/vapor, etc., in electronic, magnetic, optical, ferroelectric, piezoelectric, and dielectric applications. Sixty one papers have been processed separately for inclusion on the data base

  6. Formation and elasticity of membranes of the class II hydrophobin Cerato-ulmin at oil-water interfaces.

    Protein surfactants show great potential to stabilize foams, bubbles, and emulsions. An important family of surface active proteins, the hydrophobins, is secreted by filamentous fungi. Two hydrophobin classes have been recognized, with Class II exhibiting slightly better solubility than Class I, although neither is very soluble in water. Hydrophobins are small proteins (8-14 kDa), but they are larger and more rigid than typical surfactants such as sodium dodecyl sulfate. This rigidity seems to be manifested in the strength of adsorbed hydrophobin layers on oil droplets or air bubbles. A particular Class II hydrophobin, Cerato-ulmin, was characterized at the oil-water interface (the oil was squalane). The results are compared to measurements at the air-water interface, newly extended to lower Cerato-ulmin concentrations. For both oil-water and air-water interfaces, static and dynamic properties were measured during the evolution of the membrane structure. The static measurements reveal that dilute Cerato-ulmin solution efficiently decreases the interfacial tension, whether at oil-water or air-water interfaces. The reduction in surface tension requires several hours. Interfacial mechanics were characterized too, and the dilatational modulus was found to reach large values at both types of interfaces: 339 ± 19 mN/m at the squalane-water interface and at least 764 ± 45 mN/m at the air-water interface. Both values well exceed those typical of small-molecule surfactants, but come closer to those expected of particulate-loaded interfaces. Circular dichroism provides some insight to adsorption-induced molecular rearrangements, which seem to be more prevalent at the oil-water interface than at the air-water interface.

  7. Interface detection by neutron scattering

    1979-01-01

    A method and apparatus for detecting an interface of materials having different hydrogen content present in a metal vessel or pipe eg. made of steel, are described. Steel walls of columns, reactors, pipelines etc can be monitored. It is very suitable for detection of liquid water or hydrocarbons present in gas pipelines and also for the detection of a liquid hydrocarbon in a vessel or column. A series of measurements of the hydrogen density of the contents of a vessel or pipe are made using at least one californium-252 neutron source located near the outer side of the pipe. Neutrons are emitted and are scattered by the contents of the pipe. At least one neutron detector is located near the outer side of the metal wall. The detectors have a higher sensitivity for scattered neutrons (from the light hydrogen nuclei present in water or hydrocarbons). A source of 0.1 - 1 micrograms produces enough neutrons for most technical applications so the handling is relatively safe although shielding is advocated. The detectors contain helium-3 at a pressure of about 10 bar. Current pulses from the detector are counted. (U.K.)

  9. Analysis of the interface tracking errors

    2001-01-01

    An important limitation of the interface-tracking algorithm is the grid density, which determines the space scale of the surface tracking. In this paper the analysis of the interface tracking errors, which occur in a dispersed flow, is performed for the VOF interface tracking method. A few simple two-fluid tests are proposed for the investigation of the interface tracking errors and their grid dependence. When the grid density becomes too coarse to follow the interface changes, the errors can be reduced either by using denser nodalization or by switching to the two-fluid model during the simulation. Both solutions are analyzed and compared on a simple vortex-flow test.(author)

  10. Multiphase Microfluidics The Diffuse Interface Model

    CERN Document Server

    2012-01-01

    Multiphase flows are typically described assuming that the different phases are separated by a sharp interface, with appropriate boundary conditions. This approach breaks down whenever the lengthscale of the phenomenon that is being studied is comparable with the real interface thickness, as it happens, for example, in the coalescence and breakup of bubbles and drops, the wetting and dewetting of solid surfaces and, in general, im micro-devices. The diffuse interface model resolves these probems by assuming that all quantities can vary continuously, so that interfaces have a non-zero thickness, i.e. they are "diffuse". The contributions in this book review the theory and describe some relevant applications of the diffuse interface model for one-component, two-phase fluids and for liquid binary mixtures, to model multiphase flows in confined geometries.

    Fikkert, Wim; van der Vet, Paul; Nijholt, Anton

    In this chapter we investigated which hand gestures are intuitive to control a large display multimedia interface from a user's perspective. Over the course of two sequential user evaluations, we defined a simple gesture set that allows users to fully control a large display multimedia interface, intuitively. First, we evaluated numerous gesture possibilities for a set of commands that can be issued to the interface. These gestures were selected from literature, science fiction movies, and a previous exploratory study. Second, we implemented a working prototype with which the users could interact with both hands and the preferred hand gestures with 2D and 3D visualizations of biochemical structures. We found that the gestures are influenced to significant extent by the fast paced developments in multimedia interfaces such as the Apple iPhone and the Nintendo Wii and to no lesser degree by decades of experience with the more traditional WIMP-based interfaces.

    This publication is an output of a series of meetings to identify and evaluate issues and opportunities associated with interfaces in the back end of the fuel cycle (BEFC) and to describe effective management approaches based on the experience of Member States. During the meetings, participants from Member States and other international organizations shared and evaluated the main interfaces and potential interface issues among the spent fuel storage, transport, reprocessing and disposal of the BEFC, and also reviewed the national approaches to addressing these issues. The aim of this publication is to provide an approach to identify the interfaces in the BEFC as well as the potential issues that should be addressed. It also aims at responding to the solutions Member States most often find to be effective and, in some cases, were adjusted or revisited to reach the fixed target. Most of the interfaces and issues are country specific, as evidenced by the variety and diversity of examples provided in this publication

  13. Integrating interface slicing into software engineering processes

    1993-01-01

    Interface slicing is a tool which was developed to facilitate software engineering. As previously presented, it was described in terms of its techniques and mechanisms. The integration of interface slicing into specific software engineering activities is considered by discussing a number of potential applications of interface slicing. The applications discussed specifically address the problems, issues, or concerns raised in a previous project. Because a complete interface slicer is still under development, these applications must be phrased in future tenses. Nonetheless, the interface slicing techniques which were presented can be implemented using current compiler and static analysis technology. Whether implemented as a standalone tool or as a module in an integrated development or reverse engineering environment, they require analysis no more complex than that required for current system development environments. By contrast, conventional slicing is a methodology which, while showing much promise and intuitive appeal, has yet to be fully implemented in a production language environment despite 12 years of development.

  18. Strength of interface in stainless clad steels

    1990-01-01

    Mechanical tests were conducted on four kinds of stainless clad steels to establish test methods for determining crack growth resistance of bimaterial interface. In tension tests, smooth specimens and shallow notched specimens were employed. In these tests, all of the smooth specimens were broken in carbon steel, not along the bimaterial interface. On the other hand, most of the shallow notched specimens were broken along the interface, when the notch root was located at the interface. Therefore, the shallow notched specimens were suitable for estimating the strength of the interface in tension tests. For fracture toughness tests, chevron notched specimens are recommended, since pre-fatigue cracks were susceptible to initiate and grow in carbon steel for conventional straight notched specimens. In fatigue crack growth tests, side-grooved and non-side-grooved specimens were employed. Although the side-grooves were machined so that the minimum cross-sectional plane of the specimens coincided with the plane of the bimaterial interface, cracks did not always propagate along the interface. Therefore, the side-grooves were judged not to be effective for cracks to propagate along the bimaterial interface. Both in fracture toughness tests and fatigue tests, the crack growth resistance along bimaterial interface was much lower than the resistance of matrix steels. In all of the mechanical tests conducted, the crack growth resistance along the interface was higher for the normalized material than that for the as-rolled material. The nickel foil inserted between carbon steel and stainless steel improved the growth resistance of interfacial cracks. (author)

    with T-operation. (iii) Gauge symmetry (G), which is associated with a change in the phase of the wave-function as Ψ → e iθ Ψ. Gauge symmetry is connected to the law of charge conservation, and broken G-symmetry corresponds to superconductivity/superfluidity. To summarize, the interplay among these electronic degrees of freedom produces various forms of symmetry breaking patterns of I, T, and G, leading to novel emergent phenomena, which can appear only by the collective behavior of electrons and cannot be expected from individual electrons. Figure 1 shows this schematically by means of several representative phenomena. From this viewpoint, the interfaces of TMOs offer a unique and important laboratory because I is already broken by the structure itself, and the detailed form of broken I-symmetry can often be designed. Also, two-dimensionality usually enhances the effects of electron correlations by reducing their kinetic energy. These two features of oxide interfaces produce many novel effects and functions that cannot be attained in bulk form. Given that the electromagnetic responses are a major source of the physical properties of solids, and new gauge structures often appear in correlated electronic systems, we put 'emergent electromagnetism' at the center of Fig. 1.

    The National Spent Nuclear Fuel Program is chartered with facilitating the disposition of DOE-owned spent nuclear fuel to allow disposal at a geologic repository. This is done through coordination with the repository program and by assisting DOE Site owners of SNF with needed information, standardized requirements, packaging approaches, etc. The High Integrity Can (HIC) will be manufactured to provide a substitute or barrier enhancement for normal fuel geometry and cladding. The can would be nested inside the DOE standardized canister which is designed to interface with the repository waste package. The HIC approach may provide the following benefits over typical canning approaches for DOE SNF. (a) It allows ready calculation and management of criticality issues for miscellaneous. (b) It segments and further isolates damaged or otherwise problem materials from normal SNF in the repository package. (c) It provides a very long term corrosion barrier. (d) It provides an extra internal pressure barrier for particulates, gaseous fission products, hydrogen, and water vapor. (e) It delays any potential release of fission products to the repository environment. (f) It maintains an additional level of fuel geometry control during design basis accidents, rock-fall, and seismic events. (g) When seal welded, it could provide the additional containment required for shipments involving plutonium content in excess of 20 Ci. (10 CFR 71.63.b) if integrated with an appropriate cask design. Long term corrosion protection is central to the HIC concept. The material selected for the HIC (Hastelloy C-22) has undergone extensive testing for repository service. The most severe theoretical interactions between iron, repository water containing chlorides and other repository construction materials have been tested.

    Curry, Eric; Arey, Bruce

    2010-06-01

    The domestic apple might well be called an 'extreme' fruit. In the arid Northwest United States, the fruit often tolerates surface temperatures ranging from -2 °C in the early spring to 50 °C in the heat of summer, and again to -2 °C during controlled postharvest storage for up to 12 months. During its 18-month existence, the apple maintains a cuticle that is dynamic and environmentally responsive to protect against 1) cellular water loss during desiccation stress and 2) excessive uptake of standing surface moisture. Physiological disorders of the peel such as russeting, cracking, splitting, flecking and lenticel marking, develop as epidermal cells respond to rapid changes in ambient conditions at specific developmental stages during the growing season. Resultant market losses underlie research investigating the nature of apple cuticle growth and development. Ultrastructural analysis of the pro-cuticle using scanning electron microscopy indicates an overlapping network of lipid-based distally-elongating microtubules--produced by and connected to epidermal cells--which co-polymerize to form an organic solvent-insoluble semi-permeable cutin matrix. Microtubule elongation, aggregation, and polymerization function together as long as the fruit continues to enlarge. The nature of lipid transport from the epidermal cells through the cell wall to become part of the cuticular matrix was explored using an FEI Helios NanoLabTM DualBeamTM focused ion beam/scanning electron microscope on chemically- and cryo-fixed peel tissue from mature or freshly harvested apples. Based on microtubule dimensions, regular projections found at the cell/cuticle interface suggest an array of microtubule-like structures associated with the epidermal cell.

    Full Text Available The tangible interaction approach has, in recent years, become a promising alternative to tactile interaction for very young children. Children playing with Tangible User Interfaces (TUI are motivated by the novel and digital environment and benefit from the same values as conventional physical playing. Young children build their mental image of the world through action and motor responses and, with physical handling, they become conscious of reality. Within TUIs, digitally augmented surfaces (interactive blackboards and tabletops are becoming popular in educative environments. Tabletop devices are horizontal surfaces capable of supporting interaction and image feedback on their surface, and are especially interesting for reinforcing face-to-face social relations and group activities. However, most of current children-oriented applications for tabletops are based on tactile interaction, thus losing the benefits of physical playing. The paper describes our experiences building tangible tabletops, and designing tangible games and toys. In particular, we present NIKVision, a tabletop device intended to give leisure and fun while reinforcing physical manipulation and colocated gaming for 3-6 year old children. Several hybrid (physical/digital games based on the manipulation of passive and active toys have been developed for NIKVision. From our experience several useful lessons can be extracted. Among them, the necessity of bridging the gap between designers and developers making it easier the prototyping of tabletop games stands out. To tackle this difficulty a toolkit for the prototyping of tabletop games called ToyVision has been created. The toolkit supports designers to fully explore the physical feasibilities of the manipulation of physical playing pieces, while minimizing the technical difficulties of implementing tabletop games based on physical manipulation. This way, NIKVision and ToyVision are becoming powerful tools to develop innovative

    The Chandra Source Catalog (CSC) is intended to be the definitive catalog of all X-ray sources detected by Chandra. For each source, the CSC provides positions and multi-band fluxes, as well as derived spatial, spectral, and temporal source properties. Full-field and source region data products are also available, including images, photon event lists, light curves, and spectra. The Chandra X-ray Center CSC website (http://cxc.harvard.edu/csc/) is the place to visit for high-level descriptions of each source property and data product included in the catalog, along with other useful information, such as step-by-step catalog tutorials, answers to FAQs, and a thorough summary of the catalog statistical characterization. Eight categories of detailed catalog documents may be accessed from the navigation bar on most of the 50+ CSC pages; these categories are: About the Catalog, Creating the Catalog, Using the Catalog, Catalog Columns, Column Descriptions, Documents, Conferences, and Useful Links. There are also prominent links to CSCview, the CSC data access GUI, and related help documentation, as well as a tutorial for using the new CSC/Google Earth interface. Catalog source properties are presented in seven scientific categories, within two table views: the Master Source and Source Observations tables. Each X-ray source has one ``master source'' entry and one or more ``source observation'' entries, the details of which are documented on the CSC ``Catalog Columns'' pages. The master source properties represent the best estimates of the properties of a source; these are extensively described on the following pages of the website: Position and Position Errors, Source Flags, Source Extent and Errors, Source Fluxes, Source Significance, Spectral Properties, and Source Variability. The eight tutorials (``threads'') available on the website serve as a collective guide for accessing, understanding, and manipulating the source properties and data products provided by the catalog.

  9. The utility perspective on the transportation interface

    International Nuclear Information System (INIS)

    Bishop, R.W.

    1986-01-01

    Describing interface between the transportation system and the operating plants, the author thinks there are really three, interrelated dimensions to the interface; the technical; physical interface; the business (i.e. economic) interface; and the institutional interface. A principal mission of the Nuclear Transportation Group is to help assure that these interfaces are smoothly bridged and that the resources of the utility industry are brought to bear to achieve this result. The physical interface is the most readily understood. The analysis must also consider the ALARA (As Low As Reasonably Achievable) radiation exposure evaluation of the waste system design and operation. ALARA evaluations of the waste system design and operation. ALARA evaluations must be done on a systems basis to ensure that the effects of particular designs that may be beneficial in some aspects of the system do not adversely impact nuclear power plant workers or operations. Regardless of one's political persuasion or technical training, the author doesn't think there is any question that spent fuel must be moved, sooner or later, somewhere. It's in the best interests of all that those shipments be made safely, and economically, with the proper attention to doing it right and not needlessly wasting resources, including money

  10. Invasive Intraneural Interfaces: Foreign Body Reaction Issues

    Lotti, Fiorenza; Ranieri, Federico; Vadalà, Gianluca; Zollo, Loredana; Di Pino, Giovanni

    2017-01-01

    Intraneural interfaces are stimulation/registration devices designed to couple the peripheral nervous system (PNS) with the environment. Over the last years, their use has increased in a wide range of applications, such as the control of a new generation of neural-interfaced prostheses. At present, the success of this technology is limited by an electrical impedance increase, due to an inflammatory response called foreign body reaction (FBR), which leads to the formation of a fibrotic tissue around the interface, eventually causing an inefficient transduction of the electrical signal. Based on recent developments in biomaterials and inflammatory/fibrotic pathologies, we explore and select the biological solutions that might be adopted in the neural interfaces FBR context: modifications of the interface surface, such as organic and synthetic coatings; the use of specific drugs or molecular biology tools to target the microenvironment around the interface; the development of bio-engineered-scaffold to reduce immune response and promote interface-tissue integration. By linking what we believe are the major crucial steps of the FBR process with related solutions, we point out the main issues that future research has to focus on: biocompatibility without losing signal conduction properties, good reproducible in vitro/in vivo models, drugs exhaustion and undesired side effects. The underlined pros and cons of proposed solutions show clearly the importance of a better understanding of all the molecular and cellular pathways involved and the need of a multi-target action based on a bio-engineered combination approach.

    To quantitatively simulate microstructural evolution in real systems, we investigated three different interface models: a sharp-interface model implemented by the software DICTRA and two diffuse-interface models which use either physical order parameters or artificial order parameters. A particular example is considered, the diffusion-controlled growth of a γ ' precipitate in a supersaturated γ matrix in Ni-Al binary alloys. All three models use the thermodynamic and kinetic parameters from the same databases. The temporal evolution profiles of composition from different models are shown to agree with each other. The focus is on examining the advantages and disadvantages of each model as applied to microstructure evolution in alloys

    Clarification of the details of the interface structure between liquids and solids is crucial for understanding the fundamental processes of physical functions. Herein, we investigate the structure of the interface between tetraglyme and graphite and propose a model for the interface structure based on the observation of frequency-modulation atomic force microscopy in liquids. The ordering and distorted adsorption of tetraglyme on graphite were observed. It is found that tetraglyme stably adsorbs on graphite. Density functional theory calculations supported the adsorption structure. In the liquid phase, there is a layered structure of the molecular distribution with an average distance of 0.60 nm between layers.

Tecendo comparações entre os teóricos raciais brasileiros e os impasses mais contemporâneos, sobre a aferição de inteligência e capacidade, esse ensaio pretende provocar. Em pauta estarão as contradições que têm se destacado, mais recentemente, quando se opõem de um lado as etnicidades locais, de outro a tão propalada globalização. Tal qual dois lados de uma mesma moeda, a afirmação de identidades tem se mostrado tão evidente como o próprio estreitamento das relações internacionais.

Appointed here will be the contradictions which have, more recently grown in importance, and have opposed through one aspect, local ethnic groups and through another the greatly publicized globalization.

  17. Applying Cognitive Psychology to User Interfaces

    Science.gov (United States)

    Durrani, Sabeen; Durrani, Qaiser S.

    This paper explores some key aspects of cognitive psychology that may be mapped onto user interfaces. Major focus in existing user interface guidelines is on consistency, simplicity, feedback, system messages, display issues, navigation, colors, graphics, visibility and error prevention [8-10]. These guidelines are effective indesigning user interfaces. However, these guidelines do not handle the issues that may arise due to the innate structure of human brain and human limitations.

    Difficulty in communicating is one of the key challenges for people suffering from severe motor and speech disabilities. Often such person can communicate and interact with the environment only using assistive technologies. This paper presents a multifunctional user interface designed to improve communication efficiency and person independence. The main component of this interface is a projection mapping technique used to highlight objects in the environment. Projection mapping makes it possible to create a natural augmented reality information presentation method. The user interface combines a depth sensor and a projector to create camera-projector system. We provide a detailed description of camera-projector system calibration procedure. The described system performs tabletop object detection and automatic projection mapping. Multiple user input modalities have been integrated into the multifunctional user interface. Such system can be adapted to the needs of people with various disabilities.

    The effect of intermixing on the apparent interface stress is studied in -textured dc-magnetron sputtered Au/Ni multilayers by use of two methods commonly used for determining interface stress. The method using profilometry and in-plane x-ray diffraction does not take intermixing...... into account and yields an apparent interface stress of -8.46 +/- 0.99 J m(-2). However, observed discrepancies between model calculations and measured high-angle x-ray diffractograms indicate intermixing, and by use of the profilometry and sin(2) psi method the real interface stress value of -2.69 +/- 0.43 J...... m(-2) is found. This method also reveals a significant and systematic change of the stress-free lattice parameter of both constituents as a function of modulation period which is shown to account for the difference between the two findings.

    We report the discovery of superconductivity with an onset temperature of ∼0.6 K in a platinum-silicon interface. The interface was formed by using a unique focused ion beam sputtering micro-deposition method in which the energies of most sputtered Pt atoms are ∼2.5 eV. Structural and elemental analysis by transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy reveal a ∼ 7 nm interface layer with abundant Pt, which is the layer likely responsible for the superconducting transport behavior. Similar transport behavior was also observed in a gold-silicon interface prepared by the same technique, indicating the possible generality of this phenomenon.

    Full Text Available Many universities have applied e-learning on more than one LMS (Learning Management System platforms such as Wordpress and Moodle. In addition, difficulties implementations in developing countries have occurred. Those are mainly caused by limitations and expensive of Internet infrastructure. Therefore to increase Moodle application as an e-learning system, the paper proposed two synchronization interfaces. The first interface is for Moodle and Wordpress. This assists teachers to migrate their learning material in their blog in Wordpress into Moodle. Second interface is for Moodle portable performing offline LMS and Moodle performing online LMS. Moodle portable was installed in teachers and students notebooks. Moodle itself was installed and run in e-learning server. The aim is to improve Moodle utilization in the class. The results showed satisfied outcomes. Students and teachers could employ the interfaces easily and secure as they have to login using student/teacher ID, course ID, username and password.

  14. Biological growth in bodies with incoherent interfaces

    Science.gov (United States)

    Swain, Digendranath; Gupta, Anurag

    2018-01-01

    A general theory of thermodynamically consistent biomechanical-biochemical growth in a body, considering mass addition in the bulk and at an incoherent interface, is developed. The incoherency arises due to incompatibility of growth and elastic distortion tensors at the interface. The incoherent interface therefore acts as an additional source of internal stress besides allowing for rich growth kinematics. All the biochemicals in the model are essentially represented in terms of nutrient concentration fields, in the bulk and at the interface. A nutrient balance law is postulated which, combined with mechanical balances and kinetic laws, yields an initial-boundary-value problem coupling the evolution of bulk and interfacial growth, on the one hand, and the evolution of growth and nutrient concentration on the other. The problem is solved, and discussed in detail, for two distinct examples: annual ring formation during tree growth and healing of cutaneous wounds in animals.

    We have calculated the interface local density of states (ILDOS) formed by the transition metals Mo/Ta using a tight-binding Slater-Koster description and the Green Function matching method together with quickly converging algorithms to compute the transfer matrices. We obtain the surface LDOS as a byproduct. Our result is a useful tool to analyze experimental results and to check models as a function of the value of the tight-binding parameters either of the bulk or at the interface itself. We consider the (100) direction. We compare the interface to the bulk and to the surface and comment on some recently found experimental results for this interface. (author). 17 refs, 2 figs

    Particles added to a fluid interface can be used as a surface stabilizer in the food, oil and cosmetic industries. As an alternative to rigid particles, it is promising to consider highly deformable particles that can adapt their conformation at the interface. In this study, we compute the shapes of soft elastic particles using molecular dynamics simulations of a cross-linked polymer gel, complemented by continuum calculations based on the linear elasticity. It is shown that the particle shape is not only affected by the Young's modulus of the particle, but also strongly depends on whether the gel is partially or completely wetting the fluid interface. We find that the molecular simulations for the partially wetting case are very accurately described by the continuum theory. By contrast, when the gel is completely wetting the fluid interface the linear theory breaks down and we reveal that molecular details have a strong influence on the equilibrium shape.

    ROOT, as a scientific data analysis framework, provides extensive capabilities via Graphical User Interfaces (GUI) for performing interactive analysis and visualizing data objects like histograms and graphs. A new interface for fitting has been developed for performing, exploring and comparing fits on data point sets such as histograms, multi-dimensional graphs or trees. With this new interface, users can build interactively the fit model function, set parameter values and constraints and select fit and minimization methods with their options. Functionality for visualizing the fit results is as well provided, with the possibility of drawing residuals or confidence intervals. Furthermore, the new fit panel reacts as a standalone application and it does not prevent users from interacting with other windows. We will describe in great detail the functionality of this user interface, covering as well new capabilities provided by the new fitting and minimization tools introduced recently in the ROOT framework.

  5. On persistence interfaces for scientific data stores

    International Nuclear Information System (INIS)

    Malon, D.M.; May, E.N.

    1996-01-01

    A common dilemma among builders of large scientific data stores is whether to use a lightweight object persistence manager or a genuine object-oriented database. There are often good reasons to consider each of these strategies; a few are described in this paper. Too often, however, electing to use a lightweight approach has meant programming to an interface that is entirely different than that expected by commercial object-oriented databases. With the emergence of object database standards, it is possible to provide an interface to persistence managers that does not needlessly inhibit coexistence with (and, perhaps, eventual migration to) object-oriented databases. This paper describes an implementation of a substantial subset of the ODMG-93[1]C++ specification that allows clients to use many of today's lightweight object persistence managers through an interface that conforms to the ODMG standard. We also describe a minimal interface that persistence software should support in order to provide persistence services for ODMG implementations

Para avançar no entendimento dos princípios básicos envolvidos no fenômeno é necessária a utilização de técnicas e aparatos experimentais adequados. Neste estudo, foram realizadas medidas de concentração através da utilização de micro sonda de oxigênio, em tanque de grade oscilante. A dimensão do elemento sensor da micro sonda é da ordem de alguns micra. Os resultados demonstram a possibilidade de medir, sob condições turbulentas controladas similares às encontradas no ambiente, as flutuações de concentração de oxigênio no interior da camada limite existente imediatamente abaixo da interface ar-água.Gas transfer across the air-water interface is an important process for large-scale climate cycles as well as smaller environmental systems such as rivers, lakes, streams, and wastewater treatment basins. To improve the understanding of the basic principles involved in this phenomenon it is necessary to use suitable apparatus and experimental techniques. In this study, a microprobe has been used for measurements of oxygen concentration in an oscillating-grid tank. The microprobe has tip dimensions of the order of a few microns. The results demonstrate that it is feasible to measure, under controlled turbulence conditions that are representative for environmental situations, the fluctuating oxygen concentrations that take place in a boundary layer below the air-water interface.

Poly(3-hexylthiophene):[6,6]-phenyl-C_6_1-butyric acid methyl ester (P3HT:PCBM) were selected as research object and five PSCs based on active layers with varied morphology were fabricated. The results showed that P3HT crystalline phase and donor-acceptor (D-A) interface had an important influence on PSCs performance, which was revealed by structure characterization and J-V measurement. To further understanding the effect of phase structure and D-A interface on charge behavior. Spectroelectrochemistry measurement (SEC) was performed to characterize the steady-state optical absorption of P3HT, PCBM cation and anion in varied active layers, and the spectra difference of cations and anions was analyzed. The results were found that D-A interface could promote charge generation. P3HT crystalline phase and PCBM aggregation phase were beneficial for improving the charge transport ability. Meanwhile, the non-equilibrium transport of electron and hole in PSCs was corroborated by SEC.

Modeling the heat and salt flux at Europa's ice/ocean interface is necessary to understand the dynamics of Europa's ocean and its interaction with the upper ice shell as well as the history of active turbulence at this area. To achieve this goal, we used McPhee et al., 2008 parameterizations on Earth's ice/ocean interface that was developed to meet Europa's ocean dynamics. We varied one parameter at a time to test its influence on both; "h" the basal ice growth rate and on "R" the double diffusion tendency strength. The double diffusion tendency "R" was calculated as the ratio between the interface heat exchange coefficient αh to the interface salt exchange coefficient αs. Our preliminary results showed a strong double diffusion tendency R ~200 at Europa's ice-ocean interface for plausible changes in the heat flux due to onset or elimination of a hydrothermal activity, suggesting supercooling and a strong tendency for forming frazil ice.
