    implementation and testing of several schemes of diffuse control: P, PD, PI and diffuse PID, of which the last one was selected for having a better answer. The results obtained in the simulations of the algebraic PI and of the diffuse PID, established that the second one improved the follow up indexes and reduced the starting period and the fuel consumption. [Espanol] La presente tesis trata sobre la rehabilitacion del sistema de control para las turbinas de gas W501 de la Central de Ciclo Combinado de Gomez Palacio, de Durango, Mexico. La primera parte del desarrollo trata sobre un proceso de reingenieria de software aplicado al sistema de control digital de las turbinas de gas de la central de ciclo combinado de Comez Palacio. Este proceso fue desarrollado utilizando conceptos de varias ramas de la ingenieria: a) involucro los conocimientos de la ingenieria de software, utilizando metodos formales para el analisis del sistema original y el rediseno del nuevo sistema: b) se utilizo la ingenieria de control en el analisis de diversas estrategias de control y automatizacion utilizados para el control de turbinas de gas, con el objetivo de verificar el tipo de instrucciones y rutinas presentes dentro del software. El producto final de esta etapa es un sistema programatico modularizado, basado en diseno estructurado, que es funcionalmente un espejo del sistema original. El sistema obtenido esta conformado por cinco modulos principales los cuales se basan en un modelo propuesto originalmente para control por lotes (batch) :i) Interfaz Hombre Maquina, ii) Control Regulatorio, iii) Protecciones, iv) Secuencias logicas y v) Supervision. La segunda etapa de desarrollo fue la mejora del control de velocidad de la turbina. Cuando se controla una unidad turbogas, debe tomarse en cuenta varias etapas de operacion tales como el arranque, el control en estado estable y el apagado. El comportamiento real de la turbina durante el arranque, y principalmente el gran numero de retrocesos

  12. Umbrales para la determinación de la brecha digital: comparativa entre regiones desarrolladas

    Directory of Open Access Journals (Sweden)

    Juan-José Mendoza-Ruano

    Full Text Available Este trabajo tiene como objetivo principal establecer una escala porcentual que sirva de base metodológica para determinar la existencia o no de brecha digital entre regiones tecnológicamente desarrolladas. Una vez analizada la literatura científica observamos un claro déficit al no contar con una base estudiada que determine bajo qué parámetros se puede hablar de Brecha Digital al realizar la comparativas entre zonas. Además, contextualizamos el tema con una breve descripción de los conceptos básicos para el estudio, como son el de Sociedad de la Información, y en mucha mayor profundidad, la Brecha Digital. Las escalas planteadas son válidas para zonas geográficas de un nivel desarrollado en tecnologías de la información y la comunicación, no siendo un trabajo válido para zonas subdesarrolladas o en vías de transformación tecnológica. Se plantea por tanto cuatro niveles de brecha digital que corresponden con las siguientes escalas porcentuales: 1%-5%, 6%-10%, 11%-15%, más de 16%, respectivamente.

  13. Retos para la privacidad en la Era Digital

    Directory of Open Access Journals (Sweden)

    Noemi Milon Beltran

    2016-01-01

    Full Text Available Desde diversos campos de conocimiento, muchos autores coinciden en que actualmente nos encontramos ante un nuevo paradigma para la privacidad de la información personal de los ciudadanos. Una condición necesaria para la globalización (o mundialización ha sido la transnacionalización, no sólo de los factores de producción (tierra, capital y trabajo sino muy señaladamente de los intercambios y flujos de información. Este aumento exponencial de la acumulación y transmisión de datos ha sido posible gracias a las nuevas tecnologías de la información y comunicación, especialmente por la aparición de Internet y del fenómeno genéricamente conocido como “Big Data”, que consiste en una enorme y creciente agregación de datos sobre la vida privada, semiprivada o pública de individuos u organizaciones almacenadas y tratadas digitalmente. Los riesgos para la privacidad de la información personal resultan resultan una consecuencia directa de dos hechos: en primer lugar, la necesidad de los Estados e instituciones gubernamentales de disponer de información relativa a sus sociedades en general, y por otro lado, el beneficio que aporta la creciente mercantilización de este tipo de información, especialmente para las corporaciones privadas que la recolectan y analizan con propósitos comerciales y de marketing. En este trabajo se plantea si nos encontramos ante una sinergia entre estos dos intereses, produciéndose un desequilibrio de poder creciente, con la irrupción de algunas prácticas que atentan y vulneran claramente el derecho a la privacidad reconocido por la Declaración Universal de las Naciones Unidas. Esta investigación exploratoria justifica su utilidad en la falta de literatura que haga referencia al tema de una manera interdisciplinar. Se trata de un fenómeno donde se acaban entrelazando la sociología, la economía, así como la legislación y el derecho en ámbitos todavía recientes como es el mundo de las nuevas

    In the presented work, we investigated several digital methods of a discrimination signals from fast neutrons and gamma quanta. The experimental setup consists of a Pu-Be neutron source, a scintillation detector with an organic para-terphenyl monocrystal, and a digitizer (CAEN DT5730, 500 MS/s). Mixed waveform sequences were stored and then separated by pulse shape. Four methods were used for signals separation. Comparison of the traditional and the new methods of Figure of Merit (FOM) calculation is given. FOM = 1.5 was obtained in our setup for the minimum threshold value. A scintillation detector with a para-terphenyl crystal was used to measure neutron yield in the neutron generator with carbon nanotubes.

We conclude that the complexity of interpersonal relationships in childhood and adolescence has a new added, the digital world, potential and risks producing, promoting important future challenges for parents, governments, educational authorities and researchers.

  18. Alfabetización para una cultura social, digital, mediática y en red

    Directory of Open Access Journals (Sweden)

    González Fernández-Villavicencio, Nieves

    2012-07-01

    Full Text Available Technologies are changing the concept of literacy and of the basic skills necessary to be considered literate in a digital and networked culture. New critical, technological and social skills redefine the need to be literate and, as such, for information literacy. This requires a new term, such as Digital Literacy, in order to include the new skills and to focus more on the training of individuals rather than on the professional groups involved in the training. Several examples are presented, both within our country and beyond, of initiatives undertaken by libraries in digital literacy and in the generation of local digital content.

    Las tecnologías están cambiando el concepto de alfabetización y las competencias básicas necesarias para considerarse alfabetizado en una cultura digital y en red. Nuevas competencias mediáticas, críticas, tecnológicas, sociales, vienen a redefinir la propia necesidad de estar alfabetizado y por ende, en información, hasta el punto de exigir un término como Alfabetización digital, que aglutine las nuevas competencias, y centre más su objetivo en la formación que necesitan los individuos y menos en los colectivos profesionales implicados en esa formación. Se presentan diversos ejemplos, dentro y fuera de nuestro país, de iniciativas llevadas a cabo preferentemente por bibliotecas, en los campos de la alfabetización digital y la generación de contenidos digitales locales.

    2013-03-01

    Full Text Available Este artigo tem como objetivo abordar a problemática da exclusão digital sob o enfoque do analfabetismo funcional, salientando a importância da inclusão social efetiva como elemento importante na definição dessas terminologias. Também é objetivo do artigo observar esses conceitos quando relacionados com a aceleração das necessidades sociais e econômicas trazidas pela sociedade conectada em rede, notadamente após o advento da Web 2.0. Busca-se questionar – sem responder - se o cenário atual é de desafio desanimador ou de oportunidade para a inclusão digital. Para isso, são analisadas as conceituações trabalhadas antecipadamente, de “analfabetismo funcional” e de “exclusão digital”, em comparação com as novas necessidades e oportunidades sociais surgidas a partir da conexão instantânea oferecida pelas redes sociais e plataformas de colaboração. Para fins de ilustração otimista, são apresentados alguns exemplos de iniciativas de inclusão digital em redes sociais inclusivas, as quais obtiveram resultados satisfatórios. Ao fim, tece-se alguns comentários sobre políticas governamentais aplicadas atualmente, apenas para reflexão quanto a sua utilidade no atual cenário tecnológico.

    Directory of Open Access Journals (Sweden)

    Omar Villota Hurtado

    2018-03-01

    Full Text Available El concepto portafolio es reciente. Se introduce en el proceso educativo en 1975 para proponer que el docente efectúe investigación sistemática sobre su propio accionar. En aquel momento el marco de investigación estableció 4 momentos: observar, resolver, analizar y proponer. En 1985 se observa un docente reflexivo, dinamizador de su experiencia teórico-práctica quien retroalimenta su acción. El portafolio por tanto se convierte en metodología auto-reflexiva que recoge productos y experiencias para analizar, valorar, revisar, auto-evaluar y co-evaluar el proceso educativo. Al ingresar las Tecnologías de Información y Comunicación (TIC el portafolio se transforma en una herramienta digital que adquiere interactividad. La gestión de aprendizaje se fortalece en amplitud, adaptabilidad, flexibilidad y susceptibilidad. Con esta perspectiva actual el portafolio requiere de organización, estructura de información, rúbricas que sistematicen la evaluación ante el proceso formativo, con base en una praxis meta cognitiva. Este documento busca analizar el portafolio digital como herramienta de conocimiento para el proceso educativo, entendido desde el enfoque apoyo estratégico con el que se almacenan experiencias académicas individuales durante el desarrollo del curso. El uso del portafolio -cuyo fin sea ampliar y fortalecer la oferta académica flexible- necesita de un método para la producción y procesos, incluida la evaluación.

  10. Stop-motion para la alfabetización digital en Educación Primaria

    Directory of Open Access Journals (Sweden)

    2017-04-01

    Full Text Available A pesar de que la alfabetización digital en medios se reconoce como una de las competencias esenciales necesarias para vivir en una nueva era de los medios de comunicación, solo acaba de empezar a ganar atención en la educación primaria de Taiwán. Una de las razones es la educación orientada a los exámenes, y como consecuencia, el que se desvíe muy pocos recursos para este aprendizaje informal. La otra razón es que los educadores tienden a pensar en la educación en medios digitales como una serie de operaciones puramente técnicas, lo que podría llevar a los estudiantes de medios digitales a aprender a trabajar sin sentido. Por lo tanto, este estudio diseñó una exhibición de contenidos basada en el modelo de aprendizaje experiencial de Kolb con el fin de enseñar a los estudiantes conceptos de videos stop-motion y técnicas de producción cinematográfica. El experimento diseñado involucró a 247 estudiantes de tercer grado de primaria que fueron agrupados para visitar la exposición experiencial. Los hallazgos sugieren una mejora en los estudiantes de su conocimiento de videos stop-motion. El análisis de los vídeos producidos también muestra que han mejorado su capacidad mediática para representar sus ideas y comunicarse con los demás. A través del análisis de la influencia de la demografía en la prueba de conocimiento, los hallazgos revelan que la exposición experiencial es más efectiva para los estudiantes de primaria femeninos, y que las experiencias anteriores relevantes de los estudiantes no deberían afectar a los conocimientos adquiridos. Teniendo en cuenta estos resultados y observaciones, creemos que la exposición experimental propuesta es una forma prometedora de llevar a cabo la educación en alfabetización digital en las escuelas primarias.

  14. A Sociologia Digital: um desafio para o século XXI

    Directory of Open Access Journals (Sweden)

    Leonardo Fernandes Nascimento

    2016-04-01

    Full Text Available As características da cultura e da sociedade se alteraram profundamente na medida em que novas formas de comunicação dependentes das tecnologias digitais adquiriram um uso generalizado, modificando o modo como buscamos e produzimos informação. Entretanto, as ciências sociais ainda analisam este fenômeno de maneira tímida, negligenciando os efeitos das tecnologias digitais nas sociedades e, sobretudo, no próprio ofício da sociologia. O presente artigo descreve o modo como as mudanças tecnológicas representam um dos grandes desafios para a sociologia do século XXI, argumentando que é necessário não apenas o aperfeiçoamento de aspectos tecnológicos da pesquisa - como, por exemplo, o domínio de softwares de análise qualitativa e quantitativa e de redes sociais digitais - mas, fundamentalmente, o avanço em termos do significado epistemológico destas tecnologias para a imaginação sociológica. Na primeira seção, é apresentada a proposta da sociologia digital. Em seguida, descreve-se o fenômeno da produção massiva de dados digitais e os desafios que tal contexto coloca para a sociologia. A terceira seção avalia as implicações para a sociologia do uso de softwares. A última seção defende a necessidade urgente de uma atualização teórico-metodológica da sociologia frente à produção massiva de dados digitais. Por fim, argumenta-se que a sobrevivência da sociologia dependerá da instrumentalização tecnológica aliada a uma reflexão diante de um novo horizonte de questões da era digital.

    Full Text Available El presente trabajo aborda las posibles relaciones entre educación y medios en la sociedad actual, y el papel que le corresponde a la educación formal tanto en la integración curricular de los medios como en la alfabetización digital necesaria para el siglo XXI. Se parte de distintas concepciones y enfoques que en las últimas décadas han predominado en el estudio de los medios y en la educación y alfabetización mediáticas en el panorama internacional; se intentan subsanar algunos problemas terminológicos derivados de la riqueza idiomática del mundo global e intercultural en el que nos movemos; se buscan posturas integradoras y se propone una alfabetización para el siglo XXI que se caracteriza por ser mediática, digital, multimodal, crítica y funcional. Se analizan posibles interpretaciones de educación mediática y competencia digital prestando especial atención al actual marco normativo europeo y se advierte de dos posibles peligros: reducir la educación mediática al desarrollo de la competencia digital, y reducir la competencia digital a su dimensión más tecnológica e instrumental: centrarse en los conocimientos técnicos, en los procedimientos de uso y manejo de dispositivos y programas, olvidando las actitudes y los valores. Para evitar el reduccionismo y el sesgo tecnológico se recomienda recuperar para el desarrollo de la alfabetización mediática y de la competencia digital los enfoques más críticos e ideológicos de la educación para los medios.This article addresses some possible relationship between education and media in contemporary society and explores the role that formal education should play in both the integration of media in the curriculum and the digital literacy skills necessary for the 21st century.

    Full Text Available Asumiendo la importancia de las nuevas tecnologías en las aulas, especialmente en las actuales sociedades de la información y la comunicación, y siguiendo las recomendaciones de la Unión Europea a favor de la alfabetización mediática, el presente trabajo reflexiona acerca de la necesidad de educar no solo en los usos técnicos y eficientes de las tecnologías comunicativas, sino también en el uso responsable y cívico de las mismas, favoreciendo así los procesos participativos y deliberativos que son el sustento de una democracia viva. El sueño griego de la «isegoría», del igual derecho de todos al uso de la palabra, puede hacerse realidad en la cultura digital, si bien es cierto que un uso hiperselectivo de la tecnología comunicativa puede producir un efecto contrario: las nuevas formas de socialización pueden contribuir a la expansión de «cámaras de eco» o «nichos digitales», es decir, espacios discursivos cada vez más reducidos en donde el derecho a decir se desvincula de la responsabilidad de escuchar críticamente lo que procede de un espacio público más abierto y plural. Una de las metas de la educación en la cultura digital es precisamente frenar esta tendencia, detectada en los últimos años por autores como Sunstein, Wolton o Cortina. En el presente artículo se proponen orientaciones educativas para evitar estos sesgos y para fomentar, mediante la tecnología comunicativa, la ciudadanía digital y los valores éticos propios de sociedades democráticas.Given the importance of new technologies in the classroom, especially in today’s information and communication societies, and following European Union recommendations to promote media literacy, this article reflects the need to educate not only in technical and efficient applications of communication technologies but also in their civic and responsible use, thus promoting participatory and deliberative processes which are the lifeline of a functioning democracy

As narrativas que envolvem os jogadores de Ecocity, por exemplo, podem servir de base para pensarmos em princípios narratológicos aplicados à educação sobre TV e consumo, orientando cooperação na gestão de cidades (virtuais em que, por exemplo, num momento inicial as economias destas cidades requereriam mais energia e gerariam mais doenças e insatisfação ao focarem suas atividades numa logística de produção e distribuição de alimentos obesogênicos e num segundo momento requereriam menos energia e gerariam menos doenças e insatisfação por focarem na produção e distribuição de alimentos sustentáveis. Por um lado vemos gestos constrangedores propostos pelas propagandas obesogênicas que engendram os corpos de todos os membros das famílias para funcionarem como máquinas de produção; por outro vemos falas sendo registradas pelos jogos e redes sociais e veiculadas na TV digital.

    Full Text Available El documental tiene una historia reciente. Al contrario de lo que generalmente se afirma, entendemos que el documental no nace al mismo tiempo que el cine. Las primeras experiencias con las imágenes en movimiento tenían por objeto tan sólo registrar acontecimientos de la vida cotidiana de las personas y de los animales. Así, la contribución de los pioneros del cine para el documental fue mostrar que el material base de trabajo para el documental son las imágenes recogidas en los lugares donde ocurren los acontecimientos. O dicho de otra forma, es el registro in loco que encontramos en el inicio del cine que constituye la raíz (principio base en que se asienta la producción documental.

    Full Text Available No Brasil, normalmente os modelos digitais de elevação (MDEs são produzidos pelos próprios usuários e pouca atenção tem sido dada às suas limitações, como fonte de informação espacial. Este estudo propôs avaliar diferentes MDEs para subsidiar a escolha do modelo apropriado para derivar atributos topográficos utilizados em um mapeamento digital de solos, por redes neurais artificiais. A avaliação constou da determinação da raiz quadrada do erro médio quadrático da elevação (RMSE; análise das depressões espúrias; comparação entre drenagem mapeada e drenagem numérica, curvas de nível derivadas e curvas de nível originais, e análise das bacias de contribuição derivadas. Os resultados obtidos demonstraram que apenas o RMSE não foi suficiente para avaliar a qualidade desses modelos. O MDE, derivado de curvas de nível (CARTA, obtido com a utilização do módulo TOPOGRID apresentou qualidade superior aos MDEs derivados de sensores remotos (ASTER e SRTM. A análise qualitativa também identificou que o MDE CARTA é superior aos demais, pois estes apresentaram grande quantidade de erros que podem comprometer o estabelecimento das relações entre atributos do terreno e as condições locais de solos.In Brazil, the digital elevation models (DEMs are usually produced by users themselves and little attention has been given to their limitations as source of spatial information. The objective of this study was to evaluate different DEMs to help in choosing an appropriate model to derive topographical attributes used in a digital soil mapping based on a neural networks approach. The evaluation consisted of the following analysis: determination of root mean square error (RMSE of elevation; analysis of the spurious depressions; comparison between mapped drainage and numeric drainage and between derived contour lines and original contour lines; and analysis of the derived contribution basins. The results demonstrated that RMSE

    Full Text Available Superfícies topográficas podem ser representadas com um bom grau de precisão por meio de mapas. No entanto, estes nem sempre são as melhores ferramentas para a compreensão de relevos mais complexos. Nesse sentido, a maior contribuição desse trabalho é a especificação e implementação da arquitetura de uma plataforma de software opensource voltado para a representação de modelos digitais de terrenos baseado em TIN (Triangular Irregular Network, segundo os paradigmas da programação orientada a objetos e programação genérica e que possibilitaram a integração de várias ferramentas de linguagem aberta (opensource, tais como GDAL, OGR, OpenGL, OpenSceneGraph e Qt. Além disso, o núcleo de representação da arquitetura tem a capacidade de trabalhar com múltiplas estruturas de dados topológicas que permitem extrair em tempo constante, todas as relações de conectividade entre as entidades vértices, arestas e faces, presentes numa subdivisão planar triangular, facilitando enormemente a implementação de aplicações de tempo real. Esta capacidade é muito importante, por exemplo, na utilização de dados de levantamentos a laser (Lidar, ALS, TLS, possibilitando a geração de modelos de malhas triangulares da ordem de milhões de pontos.

    Full Text Available La publicidad en entornos de Digital Signage demanda el enriquecimiento de la aproximación clásica de recomendación orientada a individuos, a través de la entrega de anuncios para un grupo de personas que observa una pantalla pública. Aunque la precisión que se pueda lograr en las recomendaciones es importante, lo es aún más el grado de novedad que puedan percibir los usuarios. Este balance puede obtenerse no solo a través de la mejora de los algoritmos de recomendación, sino también a través de un adecuado esquema de cooperación multi-pantalla. En este sentido, el presente artículo propone una aproximación para la construcción de un sistema de recomendaciones para entornos de Digital Signage soportado en un esquema de cooperación Smart TV-Smartphone.

  10. La competencia digital de la Generación Z: claves para su introducción curricular en la Educación Primaria

    Directory of Open Access Journals (Sweden)

    2016-10-01

    Full Text Available La convergencia mediática y el uso masivo de dispositivos conectados a Internet, rasgos distintivos de la sociedad actual, provocan cambios en el modo en el que las nuevas generaciones aprenden y acceden al conocimiento. Además, emergen nuevas competencias, las digitales, que la Generación Z necesita para afrontar los retos de una sociedad digitalizada. El estudio presentado, de corte cuantitativo, con una muestra de 678 alumnos de Educación Primaria, pretende aportar evidencias empíricas sobre el nivel de competencia digital del alumnado perteneciente a dicha generación. Los resultados revelan que no adquieren habilidades digitales de forma inherente sino que precisan de educación al respecto, atisbándose el peligro de una brecha digital, no por uso o acceso a ellas, sino por falta de competencia. La ausencia de diferencia significativa en el nivel general de competencia digital entre el alumnado de diferentes cursos de la etapa de Educación Primaria refleja que, en cierta medida, ese nivel se adquiere más por convivencia con las TIC en contextos informales que por un adecuado desarrollo en el contexto escolar que potencie gradual y progresivamente su adquisición. De los resultados se desprende, por tanto, la necesidad de abordar la competencia digital en la escuela, incidiendo en el desarrollo de las áreas que la componen y potenciándola para superar el nivel de uso en la vida cotidiana y acercarla al nivel académico que facilitará su inclusión al mundo laboral.

    Full Text Available Com a implantação da TV Digital no Brasil, surge a necessidade de se fomentar a concepção e produção de conteúdos audiovisuais interativos de qualidade que apresentem mensagens educativas a partir do Edutretenimento. Este estudo propõe a aplicação da gamificação como elo comunicacional para incentivar e modificar o comportamento dos usuários, através de uma narrativa que incentive a motivação intrínseca para o entretenimento e o aprendizado nesses meios. Existem poucos modelos de roteiros para a produção de aplicativos, sobretudo educacionais, com aplicações interativas simultâneas para o fluxo televisivo ou para o conteúdo complementar da programação ofertada. Por essa razão, é atribuída uma atenção especial ao roteiro, em virtude de se inserir, em sua construção, os elementos que compõem a mecânica e a dinâmica dos jogos. Como resultado, é apresentado o verbete “Gamificação-TVDI”, bem como o desenvolvimento de uma metodologia de modelagem de conteúdo e de processo, apoiada em mapas conceituais, wireframes e roadmaps, fundamentando a concepção e a elaboração de um protótipo de roteiro com elementos de gamificação para programas educativos e seus aplicativos de interação.

    Full Text Available For at least a decade there has been a substantial and continuous output of literature advocating the development of educational programs for «digital literacy» and/or «information literacy» (known in the Spanish context as ALFIN. The authors approach this concept from an educational perspective, specifically, a didactic one. They begin by suggesting the need for redefining the meaning of literacy to adjust to the omnipresence of digital culture in the current information society. There follows a conceptualization of the concept of competent learning and of the teaching methodologies or strategies that are consistent and coherent with the development of information and digital skills. The conclusion contains suggestions about the future of information literacy for citizenship training in the 21st century.

    Desde hace, al menos, una década existe una notable y continuada producción bibliográfica que defiende la necesidad de desarrollar programas educativos de «alfabetización informacional» (conocido, en el contexto español, por ALFIN, y/o de «alfabetización digital». Los autores realizan una lectura de dicho concepto desde el ámbito pedagógico, y específicamente, didáctico. En la primera parte del trabajo se sugiere la necesidad de redefinir el sentido de la alfabetización ante la omnipresencia de la cultura digital en el actual contexto de la sociedad informacional. En la segunda se aborda la conceptualización del concepto de aprendizaje competente y de las metodologías o estrategias de enseñanza que son acordes y coherentes con el desarrollo de las competencias informacionales y digitales. Se concluye con algunas sugerencias sobre el futuro del ALFIN para la formación de la ciudadanía del siglo XXI.

    Full Text Available Medial mandibular flexure (MMF is the functional approximation of hemi-mandibles in jaw opening and protrusion, which may affect conventional or implant-supported arch prostheses. OBJECTIVE: This study evaluated the intra- and inter-rater reliability of a digital image method for linear measurement of MMF in dentate subjects. MATERIAL AND METHODS: Mandibular occlusal impressions in vinyl polysiloxane during rest and maximum opening were obtained from seven adult volunteers. Each impression and the Mitutoyo digital calipers with a 10mm opening were scanned at a 200% magnification. The images were processed using Adobe Photoshop software to get reference points on contralateral first molars. Linear intermolar measurements were taken using the Image Tool software (UTHSCSA, which was calibrated with the standard opening of the digital calipers. Intermolar distance was measured in triplicate for each image by two independent examiners. MMF was calculated by subtracting the intermolar distance in maximum opening (or protrusion from the distance in rest position. Data were analyzed by intraclass correlation (ICC tests for estimating intra- and inter-rater reliability. RESULTS: MMF values ranged from -0.21 to 0.44mm. Intra-rater ICCs were 0.982 and 0.993, and inter-rater ICC was 0.696. CONCLUSION: The present results show excellent intra-rater and good inter-rater reliability of this digital image method for measuring MMF in dentate subjects.A deflexão mandibular medial (MMF é uma deformação funcional que ocorre com a aproximação das hemi-mandíbulas em abertura e protrusão, podendo afetar próteses convencionais e implanto-suportadas em arco.

    Full Text Available The objective of this study was to assess bone density measurements for analysis of repairing fractures in rats using direct digital radiography under Dexamethasone effects. Thirty (30 young adult male Wistar rats were used, with an average weight of 200g, which were submitted to general anesthetics by ethyl ether. One rib of each animal was fractured by surgical technique. The rats were divided into 2 groups, named Control group - intraperitoneal administration of saline solution 1 hour prior to operation, and Group 1: intraperitoneal administration of Dexamethasone 0.1mg/Kg of weight 1 hour prior to operation, and two postoperative doses every 12 hours. The animals were sacrificed at 2, 3, 4, 7 and 14 days. The parts containing the hemi-thorax with the fractured rib were removed and submitted to direct digital radiography, where the linear density of the two extremities of the fracture were analyzed by the Digora System. The results showed that in the control group and in Group 1 there was a gradual and significant increase in linear density. The method used made it feasible to supply data that were statistically significant in assessing the gain in bone density during the period of time analyzed. In conclusion, direct digital radiograph is useful for bone density analysis for fracture repairing. The dose of Dexamethasone was not sufficient to alter the gain in bone density at the extremities of fracture.O objetivo deste estudo foi analisar densidade linear utilizando o sistema de radiografia digital direta intrabucal para verificar o ganho de densidade óssea em fraturas de ratos sob os efeitos da Dexametasona.

    Mammography is the image exam called 'gold standard' for early detection of breast cancer. 111 Brazil, more than eight million mammograms are carried out per year. With the advancement of technology, the digital systems CR and DR for this diagnostic modality have been increasingly implemented, replacing the conventional screen-film system, which brought environmental problems, like the disposal of chemical waste, and is also responsible for the rejection of radiographic films with processing artifacts. Digital systems, besides not experiencing the problem of environmental pollution, are still capable of image processing, allowing a much lower rejection rate when compared to the conventional system. Moreover, the determination of an accurate diagnosis is highly dependent on the image quality of the examination. To ensure the reliability of the images produced by these systems, it is necessary to evaluate them on a regular basis. Unfortunately, there is no regulation in Brazil about the Quality Assurance of these systems. The aim of this study was to develop a set of test objects that allow the evaluation of some parameters of image quality of these systems, such as field image uniformity, the linearity between the air Kerma incident on detector and the mean pixel value (MPV) of the image, the spatial resolution of the system through the modulation transfer function (MTF) and also to suggest an object to be applied in the evaluation of contrast-to-noise ratio (CNR) and signal-difference-to-noise ratio (SDNR). In order to test the objects. 10 mammography centers were evaluated, seven with CR systems and three with the DR systems. To evaluate the linearity, besides the test objects high sensitivity dosimeters were necessary to be used, namely LiF:Mg,Cu,P TL dosimeters. The use of these dosimeters was recommended in order to minimize the time required to perform the tests and to decrease the number of exposures needed. For evaluation of digital images in DICOM

    The advancement of technology in recent years has provided the production of increasingly sophisticated devices, aiming to acquire medical images with high technical level and also facilitate the operational readiness of the equipment. In order to ensure the most accurate diagnosis with minimum dose without exposing patients to obtain data and verify the performance of a radiographic system for quality control purposes we use the so-called phantoms. Phantoms are physical or computational models used to simulate the transport of ionizing radiation, their interactions in the tissues of the human body and evaluate the deposition of energy. Besides, they are made from materials with behavior similar to human tissues when exposed to ionizing radiation - the so-called tissue-equivalent materials. This paper describes the construction of a physical phantom that allows the execution of the main acceptance tests of the quality control protocols in digital radiography.

  6. A major upgrade of the sediment echosounder ATLAS PARASOUND and the digital acquisition software ParaDigMA for high-resolution sea floor studies

    The combination of the ATLAS PARASOUND sediment echosounder, designed by ATLAS Hydrographic, and the digital recording software package ParaDigMA (commercially available as ATLAS PARASTORE-3) for online digitisation, preprocessing and visualisation of recorded seismograms has proven to be a reliable system for high-resolution acoustic sea floor studies. During 10 years of successful operation aboard several research vessels, including R/V Meteor, R/V Sonne and R/V Polarstern, the system has been only slightly modified. Based on this experience, today's PARASOUND/ParaDigMA system has accomplished the step from DOS towards Windows platform and network capability. In cooperation of ATLAS Hydrographic and the Department of Earth Sciences, University of Bremen a major upgrade of the PARASOUND/ParaDigMA system has been developed that adds significant functionality for surveys of sediment structures and sea floor morphology. The innovations primarily concern the control section of the ATLAS PARASOUND echosounder and the ParaDigMA user front end. The previous analogue PARASOUND control terminal has been replaced by a small real time control PC responsible for the control of the echosounder as well as for the continuous digitisation of the data. The control PC communicates via standard network protocols metadata and data with client applications that can display and store the acquired data on different computers on the network. The new network capabilities of the system overcome former limitations and admit a high flexibility with respect to numbers and locations of operator and recording/display PCs. The system now offers a simultaneous parallel registration of the 2.5-5.5kHz parametric signal and the 18kHz NBS signal. This feature in combination with the recording of complete soundings including the entire water column provides the basis for evolving scientific research topics e. g. gas venting. The ParaDigMA recording software now operates on Windows platforms which

Ressalta-se que a produção do conhecimento, na atualidade, é uma questão fundamental, tratando-se de uma teoria voltada à sua própria prática: ao mesmo tempo em que a fundamenta, subordina-se a ela, implicando necessariamente em mudanças no modo de pensar/atuar das pessoas. A educação também é parte desse cenário de mudanças e existem razões para que seja um referencial diferenciado na chamada “ sociedade em rede”, sendo uma situação emergente a mudança de postura no que diz respeito à migração da sua identidade como transmissora de informação e de cultura para uma condição de ensinar a aprender e a pensar, preparando pessoas para que prolonguem os benefícios da escola além da escola mesma, tornando funcionais os conhecimentos adquiridos e, sobretudo, para que saibam empregar o poder da inteligência na vida profissional e no seu cotidiano. Desse modo, enfatiza-se a importância da educação, sob enfoque de um novo paradigma conceitual e prático, voltada para a formação de cidadãos capazes de integrarem-se à era digital, cujo princípio fundamental acha-se embasado no desenvolvimento de competências para o uso da informação e na capacidade intelectual de transformá-la em conhecimento., com uma inovadora condição de aprendizado contínuo e crescente. Tudo isso frente aos desafiadores avanços tecno-científicos dos últimos tempos. A desinformação nessa era é talvez a razão da existência de muitos problemas sociais, uma vez que atinge o ser humano em sua maior propriedade: a racionalidade. O conhecimento é, portanto, o fator competitivo entre as pessoas e as sociedade, sendo importante ressaltar que do seu uso racional e da sua aplicação é que

Palavras-chave repositórios digitais; representação iterativa; folksonomia; folksonomia assistida; web semântica; recuperação da informação; ontologia Abstract Information retrieval has been much discussed within Information Science lately. The search for quality information compatible with the users’ needs became the object of constant research.Using the Internet as a source of dissemination of knowledge has suggested new models of information storage, such as digital repositories, which have been used in academic research as the main form of autoarchiving and disseminating information, but with an information structure that suggests better descriptions of resources and hence better retrieval.Thus the objective is to improve the process of information retrieval, presenting a proposal for a structural model in the context of the semantic web, addressing the use of web 2.0 and web 3.0 in digital repositories, enabling semantic retrieval of information through building a data layer called Iterative Representation.The present study is characterized as descriptive and analytical, based on document analysis, divided into two parts: the first, characterized by direct observation of non-participatory tools that implement digital repositories, as well as digital repositories already instantiated, and the second with scanning feature, which suggests an innovative model for repositories, with the use of structures of knowledge representation and user participation in building a vocabulary domain. The model suggested and proposed ─ Iterative Representation ─ will allow to tailor the digital repositories using Folksonomy and also controlled vocabulary of the field in order to generate a data

La competencia espacial se puede desarrollar mediante la realización de ejercicios y la creatividad mejora, si el diseño de los ejercicios permite múltiples soluciones. La comprensión del relieve topográfico es necesaria para la integración de proyectos de arquitectura e ingeniería en el entorno. Sin embargo, en la formación universitaria se han detectado carencias para la interpretación de las formas del relieve. Las maquetas de terreno, pueden ayudar a suplir esta carencia. La aparición de tecnologías de fabricación digital de bajo coste permiten la creación de maquetas de terreno y su incorporación en la docencia reglada. En este artículo se presentan los resultados de dos experiencias. En la primera, llevada a cabo durante el curso 2015-16 con 33 alumnos universitarios, se realizan maquetas topográficas utilizando secciones apiladas, con el objetivo de mejorar la interpretación tridimensional de las formas del terreno. La segunda parte de la experiencia, llevada a cabo durante el curso 2016-17 se realiza con alumnos de Máster.

    Full Text Available Resumo: Este artigo mostra a relação entre estratégias usadas em dicionários escolares e enciclopédias digitais, especificamente em relação às remissivas ou links, que desempenham um importante papel em sua constituição. Assim, tomando por ponto de partida um verbete de um dicionário impresso e um artigo da Wikipédia, estabelecemos algumas comparações de modo a observar se se pode considerar um indício de transmutação do gênero verbete. Há que se considerar, pois, que atualmente vivenciamos um período de mudanças nas formas de interação com os textos, visto que as novas tecnologias nos impelem a transcender o simples folhear do papel, ou o movimento sacádico dos olhos entre as palavras, para a visualização difusa das informações que aparecem na tela do computador. Assim é que, com base nos conceitos metalexicográficos e hipertextuais, acreditamos que há um relacionamento extremamente relevante entre os links e as remissivas, que pode explicar o desenvolvimento de estratégias específicas de consulta, tanto em meio digital quanto impresso. No entanto, ainda não podemos precisar se isso se configura como uma reelaboração de gêneros. Palavras-chave: Verbete; reelaboração de gêneros; hipertexto digital. Abstract: This article shows the relationship between strategies used in learner’s dictionaries and online encyclopedias, specifically in relation to cross-references or links, which play an important role in its constitution. Thus, taking as a starting point of a dictionary entry form and an Wikipedia article, we establish some comparisons in order to see if it can be considered a sign of transmutation of the genre entry. One must consider, therefore, that currently we live an age of changes in the forms of interaction with the texts as new technologies compel us to transcend the simple sheet of paper, or saccadic eye movement between words, for viewing diffuse the information that appears on the computer

Esto ha generado nuevas formas de consumo radiofónico y consumidores proactivos y, como consecuencia, las emisoras han creado un tipo de programas que no han sido emitidos a través de las ondas y que ahora se alojan en las webs de las principales cadenas españolas. La que más apuesta por esta novedosa forma de emisión es COPE y es la que se somete a estudio. Se analizan, a través de métodos cuantitativos y cualitativos, 2 emisiones de cada uno de los 16 programas. Los resultados indican que son descargables y que sólo se emiten a través de Internet, que su duración es variable y que los géneros más usados son los de información y opinión, el contenido es diferente al de la radio tradicional (analógica, cuentan con publicidad aunque en su mayoría es autopromoción y, por último, todos cuentan con páginas en Facebook y Twitter que por otra parte son las preferidas por los oyentes, las más usadas, en las que comparten enlaces a los programas y opinan sobre estos.

    Full Text Available A morfometria do relevo constitui-se em parâmetro importante para a avaliação da potencialidade morfogenética dos terrenos. Dentre as diversas variáveis passíveis de mensuração, a dissecação horizontal ganha relevância ao permitir avaliar os processos morfogenéticos relacionados com a intensidade da dinâmica fluvial. Com o desenvolvimento das técnicas cartográficas digitais, a obtenção desse tipo de dado, que tradicionalmente envolvia um trabalho moroso, tem evoluído bastante. O objetivo desse artigo é apresentar e discutir uma nova técnica automática desenvolvida em meio digital para a aquisição de dados da dissecação horizontal do relevo. Apresenta-se ainda uma análise comparativa de mapeamentos realizados de forma semiautomática e automática da bacia hidrográfica do Córrego do Cavalheiro (Analândia - SP, na escala de 1:10.000. Os resultados obtidos demonstram que a técnica digital permite maior precisão e demanda menor tempo para ser executada. Além disso, a replicabilidade é garantida em razão do uso de algoritmos computacionais, dispensando a subjetividade inerente aos processos analógicos.

    Full Text Available Neste trabalho é proposta uma estratégia simples para determinação simultânea de nitrito e amônia empregando spot test e imagem digital. O método é baseado na reação do nitrito com a sulfanilamida, formando um cátion de diazônio que posteriormente é acoplado ao dicloreto de N-(1-nafitil etilenodiamina formando uma diazo composto de coloração rósea. A determinação da amônia foi realizada empregando a reação de berthelot modificada, onde o íon amônio em presença de salicilato, nitroprussiato e hipoclorito reage formando um composto de coloração verde. Os sinais analíticos foram obtidos a partir das intensidades de coloração por imagem digital no spot test do produto da reação. Após otimizações do sistema de análise e detecção, as seguintes figuras de mérito foram obtidas: concentração linear entre 0,2 a 10,0 mg L-1 para nitrito e 1,0 a 10,0 mg L-1 para a amônia. Os limites de detecção para o nitrito e amônia foram 0,05 mg L-1 e 0,27 mg L-1, respectivamente. A estratégia proposta foi aplicada com sucesso na determinação de nitrito e amônia em amostras de água subterrânea da zona urbana da cidade de Barreiras-Ba.

    Full Text Available This article analyzes the evolution of the concepts I–literacy, E–literacy, informational alphabetization (ALFIN as in Spanish and Digital Divide, to find a common ground to complement conceptually the measuring of the divide. The convergence process between I–Literacy and E–Literacy has been retrieved, reaching the final concept of informational alphabetization (ALFIN as acronym of the Spanish expression 'ALFabetización INformacional'. To propose its differentiation into three levels: the basic level of verbal–technological codification, second level for meta–analysis, and upper level for ethical–critical action. This proposal aims to rethink the digital divide, raising questions about the meaning of measurement, and the necessary precautions to avoid confusing measurement with assimilation. We state that the concept of information literacy (ALFIN – informational alphabetization should feed the study of the Digital Divide, and describe how this could affect the pyramid model of ICT appropriation developed by the author. In further research about digital exclusion The Pandora's box quality of the Web is emphasized. It can reinforce exclusion, threatens democracy and freedom in the absence of a literate digital citizen, if further simplification is carried under the access–to–infrastructure model, if the citizens' formation in capabilities that exceed the instrumental. We conclude that measuring these meta–analysis and ethical–critical action skills is the advisable way to build a metric for the digital divide. We warn about the possibility of finding a second–order divide much larger and complex than the access divide.

    2002-01-01

    This work is focused on the geotectonic context of the Carajas Mineral Province, Amazon Craton, which represents the most important Brazilian Mineral Province and hosts iron, cooper, gold, manganese and nickel deposits. At the end of Archean age, during the techno-metamorphic evolution, moderated alkaline granitoids were generated, such as, Estrela Granite Complex (EGC). This work has used digital integration products with the purpose of study the granite suite, its host rock, and the surrounded area. The digital integrated data were gamma-ray and geological data with satellite images (SAR-SAREX e TM-Landsat). The geophysics data, originally in 32 bits and grid format, were interpolated and converted to 8 bits images. The geological data (facies map) was digitalized and converted to a raster format. The remote sensing images were geometrically corrected to guarantee an accuracy on the geological mapping. On the data processing phase, SAR images were digital integrated with gamma-ray data, TM-Landsat image and the raster facies map. The IHS transformation was used as the technique to integrate the multi-source data. On the photogeological interpretation, SAR data were extremely important to permit the extraction of the main tectonic lineaments which occur on the following directions: +/- N45W, +/- N70W, +/- NS, +/- N20E, +/- N45E e +/- N75E. This procedure was done both in analogic and automatic form, being the automatic process more useful to complement information in the extracting process. Among the digital products generated, SAR/GAMA products (uranium, thorium and total count) were the ones that give the most important contribution. The interpretation of the SAR/GAMA's products added to the field campaign have allowed to map the limits of units that occur in the region and four facies of the Estrela Granite Complex were detected. The origin of the granite suite might be related to a magmatic differentiation or to distinct intrusion pulses. The use of the

El último gran auge que experimenta la EAD lo hace merced a la tecnología, se produce por la convergencia de dos líneas de desarrollo, cuya distancia ha constituido una gran brecha: La necesidad del aprendizaje a lo largo de la vida debido al crecimiento acelerado de los conocimientos científicos, tecnológicos, de los procedimientos técnicos, industriales, comerciales y la falta de respuesta en la organización de los procesos de formación. La extensión y generalización de las redes y del acceso a ellas supone de forma general la posibilidad de cerrar o atenuar esta brecha. No obstante la EAD tecnológica presenta a su vez otros problemas que se convierten en brechas a su vez, o que provocan un aumento de la gran brecha: Elementos que operan como discriminadores añadiendo nuevo requisitos a los ya existentes. Nuevos obstáculos que en el caso extremo pueden dar lugar a que se plantee cierta modalidad de e-learning que opere a su vez como una brecha al precisar adiestramientos específicos, requisitos que afecten a condiciones personales, humanas, culturales, o económicas, o requerir conocimientos discriminatorios. Para nosotros, el recurso más importante para combatir estos nuevos motivos de discriminación es definitivamente la gestión de la calidad basada en el usuario y en las comunidades de usuarios. La lucha contra estas brechas se debe dar a partir de una evaluación y de una gestión de la calidad formativa específica, y no centrada en el beneficio o en los resultados, como en el modelo clásico, ni en la satisfacción del cliente, como en los planteamientos de la calidad total.

Since the evaluation will depend on the angular readings that are carried out in the mentioned spectra, it is required of a good definition of the curves for its angular reading. Well-known the problem of the no enough definition of the spectra to be able to carry out the angular reading, it was proceeds to outline a possible solution which consists on making a mathematical treatment to the spectra with the purpose of being able to define the angular positions of interest and to correct some operation factors that appear in the spectra.

    Brody, W.R.

    1984-01-01

    Digital Radiography begins with an orderly introduction to the fundamental concepts of digital imaging. The entire X-ray digital imagining system is described, from an overall characterization of image quality to specific components required for a digital radiographic system. Because subtraction is central to digital radiographic systems, the author details the use of various subtraction methods for image enhancement. Complex concepts are illustrated with numerous examples and presented in terms that can readily be understood by physicians without an advanced mathematics background. The second part of the book discusses implementations and applications of digital imagining systems based on area and scanned detector technologies. This section includes thorough coverage of digital fluoroscopy, scanned projection radiography, and film-based digital imaging systems, and features a state-of-the-art synopsis of the applications of digital subtraction angiography. The book concludes with a timely assessment of anticipated technological advances

The content of the research consists of the interaction of culture, information, digital culture, intellectual technologies, and digital library concepts. The study is an entry work to integrity of digital culture and digital library theories and aims to expand the symmetry. The purpose of the study is to emphasize the relation between the digital culture and digital library theories acting intersection of the subjects that are examined. Also the perspective of the study is based on examining the literature and analytical evaluation in both studies (digital culture and digital library. Within this context, the methodology of the study is essentially descriptive and has an attribute for the transmission and synthesis of distributed findings produced in the field of the research. According to the findings of the study results, digital culture is an inclusive term that describes the effects of intellectual technologies in the field of information and communication. Information becomes energy and the spectrum of the information is expanding in the vertical rise through the digital culture. In this context, the digital library appears as a new living space of a new environment. In essence, the digital library is information-oriented; has intellectual technology support and digital platform; is in a digital format; combines information resources and tools in relationship/communication/cooperation by connectedness, and also it is the dynamic face of the digital culture in time and space independence. Resolved with the study is that the digital libraries are active and effective in the formation of global knowing and/or mass wisdom in the process of digital culture.

    This work is focused on the geotectonic context of the Carajas Mineral Province, Amazon Craton, which represents the most important Brazilian Mineral Province and hosts iron, cooper, gold, manganese and nickel deposits. At the end of Archean age, during the techno-metamorphic evolution, moderated alkaline granitoids were generated, such as, Estrela Granite Complex (EGC). This work has used digital integration products with the purpose of study the granite suite, its host rock, and the surrounded area. The digital integrated data were gamma-ray and geological data with satellite images (SAR-SAREX e TM-Landsat). The geophysics data, originally in 32 bits and grid format, were interpolated and converted to 8 bits images. The geological data (facies map) was digitalized and converted to a raster format. The remote sensing images were geometrically corrected to guarantee an accuracy on the geological mapping. On the data processing phase, SAR images were digital integrated with gamma-ray data, TM-Landsat image and the raster facies map. The IHS transformation was used as the technique to integrate the multi-source data. On the photogeological interpretation, SAR data were extremely important to permit the extraction of the main tectonic lineaments which occur on the following directions: +/- N45W, +/- N70W, +/- NS, +/- N20E, +/- N45E e +/- N75E. This procedure was done both in analogic and automatic form, being the automatic process more useful to complement information in the extracting process. Among the digital products generated, SAR/GAMA products (uranium, thorium and total count) were the ones that give the most important contribution. The interpretation of the SAR/GAMA's products added to the field campaign have allowed to map the limits of units that occur in the region and four facies of the Estrela Granite Complex were detected. The origin of the granite suite might be related to a magmatic differentiation or to distinct intrusion pulses. The use of the

    Mammography represents one of the most demanding radiographic applications, simultaneously requiring excellent contrast sensitivity, high spatial resolution, and wide dynamic range. Film/screen is the most widely extended image receptor in mammography due to both its high spatial resolution and contrast. The film/screen limitations are related with its narrow latitude, structural noise and that is at the same time the medium for the image acquisition, storage and presentation. Several digital detector made with different technologies can overcome these difficulties. Here, these technologies as well as their main advantages and disadvantages are analyzed. Also it is discussed its impact on the mammography examinations, mainly on the breast screening programs. (Author).

    Directory of Open Access Journals (Sweden)

    Marcella Albaine Farias da Costa

    2014-09-01

    Full Text Available Este texto admite como base inicial de reflexão as muitas articulações que já se fizeram no campo educacional em torno dos significantes ‘ensino’ e ‘tecnologia’, em geral, fixando sentidos ligados à ideia de ‘inovação’, ‘afinamento com os novos tempos’ e/ou ‘facilitador da aprendizagem’. No caso da disciplina História, fala-se recorrentemente que a utilização das chamadas tecnologias da informação e da comunicação (TICs pode gerar novas práticas, indo de encontro ao tão combatido ensino ‘tradicional’, ligado à ‘lógica da memorização’. Sem refutar ou corroborar tais afirmativas, e amparando-se nas contribuições das teorizações do discurso formuladas por Ernesto Laclau e Chantal Mouffe, a análise procura mostrar que fixar e disputar ‘sentidos de digital’ no currículo de História é uma ação política, que mobiliza/desloca a fronteira da própria definição do que é e do que não é a ciência/conhecimento histórico na contemporaneidade, provocando alterações, portanto, tanto na cultura histórica, quanto na cultura escolar. Tendo como empiria o Edital do Programa Nacional do Livro Didático (PNLD 2015, entendido como texto curricular, o estudo evidencia e problematiza a forma como as disputas em torno da significação e fixação de ‘sentidos de digital’ têm aparecido na área de História, produzindo deslocamentos em meio às práticas articulatórias que fixam sentido para a interface ‘ensino’-‘tecnologia’.

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Las tecnologías móviles están aumentando su presencia en las aulas. Mientras estas tecnologías ofrecen oportunidades para facilitar el aprendizaje, entre ellas la adquisición de una segunda lengua (L2, su potencial sigue sin aprovecharse plenamente. Aunque las aplicaciones de las tablets permiten la escritura y tareas similares a las que pueden hacerse en papel, siguen ofreciendo mayoritariamente ejercicios de selección múltiple o de relleno de huecos. Este cambio en medio y modalidad de práctica podría significar un impacto en el aprendizaje de una segunda lengua. Basada en la perspectiva de la cognición incorporada, nuestra hipótesis predice que el hecho de escribir se traduce en un mejor proceso de memorización y una mejor ortografía frente a la mecanografía o al uso de ejercicios de opción múltiple. Esta hipótesis ha sido comprobada en un estudio cuasi-experimental basado en el aula: alumnos (N=282 que practicaron vocabulario de francés a través de tres modalidades de práctica: ejercicios de opción múltiple, escritura con un teclado y escritura a mano alzada. Aunque se haya encontrado que las tres modalidades de práctica apoyaron al proceso de aprendizaje, los resultados demostraron que los alumnos que practicaron el vocabulario escribiendo con lápiz o con la tablet obtuvieron puntuaciones más altas en ortografía y dominio de signos diacríticos comparados con los alumnos que realizaron ejercicios de selección múltiple. Pasar más tiempo aprendiendo vocabulario a un nivel más alto de procesamiento conduce a una mayor adquisición de vocabulario.

Essas foram avaliadas quanto ao seu potencial em predizer a ocorrência e distribuição de classes de solos na região dos municípios de Ibirubá e Quinze de Novembro (RS. A partir de modelo numérico de terreno digital (MNT com 90 m de resolução, foram calculadas variáveis de terreno topográficas (elevação, declividade e curvatura e hidrográficas (distância dos rios, índice de umidade topográfica, comprimento de fluxo de escoamento e índice de poder de escoamento. Foram então estabelecidas regressões logísticas múltiplas entre as classes de solos da região com base em levantamento tradicional na escala 1:80.000 e as variáveis de terreno. As regressões serviram para calcular a probabilidade de ocorrência de cada classe de solo, e o mapa final de solos estimado foi produzido atribuindo-se a cada célula do mapa a denominação da classe de solo com maior probabilidade de ocorrência. Observou-se acurácia geral (AG de 58 % e acurácia pelo coeficiente Kappa de Cohen de 38 %, comparando-se o mapa original com o mapa estimado dentro da escala original. Uma simplificação de escala foi pouco significativa para o aumento da acurácia do mapa, sendo 61 % de AG e 39 % de Kappa. Concluiu-se que as regressões logísticas múltiplas apresentaram potencial preditivo para serem usadas como ferramentas no mapeamento supervisionado de solos.Logistic nominal regressions establish mathematical relations between continuous or discrete independent variables and discrete dependent variables.

    Digital printing is described as a tool to replace conventional printing machines completely. Still this goal was not reached until now with any of the digital printing technologies to be described in the paper. Productivity and costs are still the main parameters and are not really solved until now. Quality in digital printing is no problem anymore. Definition of digital printing is to transfer digital datas directly on the paper surface. This step can be carried out directly or with the use of an intermediate image carrier. Keywords in digital printing are: computer- to-press; erasable image carrier; image carrier with memory. Digital printing is also the logical development of the new digital area as it is pointed out in Nicholas Negropotes book 'Being Digital' and also the answer to networking and Internet technologies. Creating images text and color in one country and publishing the datas in another country or continent is the main advantage. Printing on demand another big advantage and last but not least personalization the last big advantage. Costs and being able to coop with this new world of prepress technology is the biggest disadvantage. Therefore the very optimistic growth rates for the next few years are really nonexistent. The development of complete new markets is too slow and the replacing of old markets is too small.

    A FORTRAN program is presented for the use of digital terrain elevation models with raster format of the Instituto Nacional de Estadistica, Geografia e Informatica of Mexico (INEGI). This program allows the selection of a data window that can be delimited, optionally, giving the extreme coordinates in degrees, minutes and seconds or in UTM (Universal Transversal Mercator) coordinates. Digital terrain data are selected to produce an output file in SURFER binary grid format with decimal degrees coordinates. Optionally an x, y, z output file in ASCII code permits the griding with commercial software to produce a map with planar rectangular coordinates. During the window selection a simple filtering process is performed to diminish numerical errors of the original file, and if it is wanted, an undersampling can be conducted to prepare less detailed maps of great coverage. This program has been extensively tested in the Gerencia de Proyectos Geotermoelectricos de la Comision federal de Electricidad (CFE) in Mexico, where it is used to prepare base maps, automatically traced topographic profiles and boundary condition for thermal modelling. Another direct uses are the calculus of terrain and isostatic corrections for gravity studies, topographic height estimating based on known horizontal coordinates, climatic effects modelling, automatic calculus of material volumes and many more.

    Two observers conducted a blind evaluation of 100 mammography files, including 47 malignant cases. Films were read both before and after image digitization at 50 μm and 100 μm with the FilmDRSII. Digitization permitted better analysis of the normal anatomic structures and moderately improved diagnostic sensitivity. Searches for microcalcifications before and after digitization at 100 μm and 50 μm showed better analysis of anatomic structures after digitization (especially for solitary microcalcifications). The diagnostic benefit, with discovery of clustered microcalcifications, was more limited (one case at 100 μm, nine cases at 50 μm). Recognition of microcalcifications was clearly improved in dense breasts, which can benefit from reinterpretation after digitization at 50 μm rather 100μm

    Digital projection radiography may replace conventional radiography some day, provided it can meet several requirements: equal or better diagnostic effectiveness of the screen-film systems; reasonable image cost; real improvement in the productivity of the Departments of Imaging. All digital radiographic systems include an X-ray source, an image acquisition and formatting sub-system, a display and manipulation sub-system, and archiving subsystem and a laser editing system, preferably shared by other sources of digital images. Three digitization processes are available: digitization of the radiographic film, digital fluorography and phospholuminescent detectors with memory. The advantages of digital fluoroscopy are appealing: real-time image acquisition, suppression of cassettes; but its disadvantages are far from negligible: it cannot be applied to bedside radiography, the field of examination is limited, and the wide-field spatial resolution is poor. Phospholuminescent detectors with memory have great advantages: they can be used for bedside radiographs and on all the common radiographic systems; spatial resolution is satisfactory; its current disadvantages are considerable. These two systems, have common properties making up the entire philosophy of digital radiology and specific features that must guide our choice according to the application. Digital fluorography is best applied in pediatric radiology. However, evaluation works have showed that it was applicable with sufficient quality to many indications of general radiology in which a fluoroscopic control and fast acquisition of the images are essential; the time gained on the examination may be considerable, as well as the savings on film. Detectors with memory are required for bedside radiographs, in osteoarticular and thoracic radiology, in all cases of traumatic emergency and in the resuscitation and intensive care departments

    X-ray radiography is a very common technique used to check the homogeneity of a material or the inside of a mechanical part. Generally the radiation that goes through the material to check, produced an image on a sensitized film. This method requires time because the film needs to be developed, digital radiography has no longer this inconvenient. In digital radiography the film is replaced by digital data and can be processed as any computer file. This new technique is promising but its main inconvenient is that today its resolution is not so good as that of film radiography. (A.C.)

    Full Text Available The huge amount of multimedia contents available on the World-Wide-Web is beginning to raise the question of their protection. Digital watermarking is a technique which can serve various purposes, including intellectual property protection, authentication and integrity verification, as well as visible or invisible content labelling of multimedia content. Due to the diversity of digital watermarking applicability, there are many different techniques, which can be categorised according to different criteria. A digital watermark can be categorised as visible or invisible and as robust or fragile. In contrast to the visible watermark where a visible pattern or image is embedded into the original image, the invisible watermark does not change the visual appearance of the image. The existence of such a watermark can be determined only through a watermark ex¬traction or detection algorithm. The robust watermark is used for copyright protection, while the fragile watermark is designed for authentication and integrity verification of multimedia content. A watermark must be detectable or extractable to be useful. In some watermarking schemes, a watermark can be extracted in its exact form, in other cases, we can detect only whether a specific given watermarking signal is present in an image. Digital libraries, through which cultural institutions will make multimedia contents available, should support a wide range of service models for intellectual property protection, where digital watermarking may play an important role.

    Full Text Available The leaf area index (LAI of a vineyard (Vitis vinifera L. cv. Cabernet Sauvignon located in the commune of Cauquenes, Maule Region in Chile, was estimated from digital images obtained with a commercial camera using two indirect methods: Leaf Area Gap and Brightness (LAGB and -Photogrammetric Leaf Area Quantification System (PLAQS. The latter requires deleafing of the grapevine. In a normalized difference vegetation index (NDVI map, three points of vine vigor were selected: high, medium, and low for which horizontal and vertical images were obtained. Images were filtered with the Arc View GIS 3.1 program to provide only leaf images and corresponding pixel numbers. Image area and square meters per linear meter were calculated. The best models were selected from  three linear regression adjustments: i LAI of LAGB vertical images of with LAI of PLAQS, ii LAI of PLAQS horizontal images with and, iii LAI of both types of images with PLAQS. The parameters in all models were significant. Adjustment between the LAGB and PLAQS vertical images provides greater simplicity and easy calculation since it requires only a vertical image to estimate LAI. Images thus obtained can accurately estimate LAI in this type of cultivar.En un viñedo (Vitis vinifera L. cv.

    There are some tensions between high-level policy definitions of “digital literacy” and actual teaching practice. We need to find workable definitions of digital literacy; obtain a better understanding of what digital literacy might look like in practice; and identify pedagogical approaches, which...... support teachers in designing digital literacy learning. We suggest that frameworks such as Problem Based Learning (PBL) are approaches that enable digital literacy learning because they provide good settings for engaging with digital literacy. We illustrate this through analysis of a case. Furthermore......, these operate on a meso-level mediating between high-level concepts of digital literacy and classroom practice....

  11. Progress in digital radiography

    Because of its practical aspect digital radiography is more and more used in the industrial sector. There are 2 kinds of digital radiography. First, the 'computed radiography' that uses a photon-stimulated screen, and after radiation exposure this screen must be read by an analyser to get a digit image. The second type is the 'direct radiography' that allows one to get a digit radiograph of the object directly. Digital radiography uses the same radioactive nuclides as radiography with silver films: cobalt, iridium or selenium. The spatial resolution of digital radiography is less good than with classical silver film radiography but digital radiography offers a better visual contrast. (A.C.)

Entretanto, muitos usuários encontram dificuldades na interação com certas interfaces, o que torna a busca por in-formações desestimulante e muitas vezes estressante. Com a aplicação do agente de interface busca-se avaliar a atuação deste tipo de software como facilitador da interação do usuário com acervos disponíveis, via catálogos digitais. E ainda verificar através do experimento com o protótipo, baseado na metodologia de avaliação heurística quais ações deverão ser tomadas para a correção dos erros que afetam a usabilidade da interface, além de confirmar a hipótese de eficácia de um sistema dessa natureza. Como resultado demonstra-se a construção de um sistema que utiliza ação interdisciplinar entre a Ciência da Informação e a Ciência da Computação na otimização de busca às informações disponíveis em catálogos digitais e na Internet com a ação de um agente de interface como mediador.

    This article presents a new method to obtain subtransmission nets equivalents, expressed in form of digital filters of finite answer to the impulse, for transitory simulations in great power nets. Initially, it has been made considerations in the way of obtaining these filters, showing that they basically have been synthesized from the impedance and admittance functions of the secondary electric net to be processed in terms of equivalents in the domain of the w analogical frequency. It also is shown the transference technique to the time domain, in which it is used the z plane of the digital frequencies as an intermediate plane, being obtained from this way a set of equations susceptible of being implemented in program of transitory simulation in the time domain. The evaluation of this new method and evaluation of the reduction effect in the order of representative filters of the equivalents, are executed through the comparison of simulations which use the new technique together with other ones coming from EMTP. The obtained replies have demonstrated the effectiveness of the proposed method, opening new possibilities for transitory simulations in great power nets.

    With digital multilayer tomography a sequence of projection images is recorded by an image intensifier television system and stored as digital data during a linear run of a layer sequence. Using this data record, tomograms of the examined body region can be computed for any layer thickness by shifts and superimposition of the single projections later at a digital workstation. The qualities of digital and conventional tomograms are basically comparable. A drawback of digital tomography is its lower local resolution (512 x 512 image matrix), advantages are a lower radiation exposure, a shorter patient examination time, and the facilities of digital image processing (later processing, archive setup, transmission).

    The use of body simulators to control the quality of X-ray images is a practice that guarantees the control of essential parameters for diagnosis by the technique. The evolution of the equipment, between the analogue, digital computerized radiology (CR) and direct radiography (DR), requires evaluation of the equivalence in grayscale, of simulators, for an adjustment according to the specific technology of obtaining the image. In this sense, the present work presents the evaluation of a body simulator with regard to the representation of mean values of signal, noise and contrast obtained in chest radiographs and panoramic of the abdomen. For the thorax the cardiac region was considered as simulation target and for the abdomen simulation of the liver and small intestine. We used a retrospective study of images obtained with X-ray equipment - CR system, in which the images were studied using the ImageJ program, generating a data catalog. These were subsequently compared with those obtained experimentally using gel filled polymer body simulator. For the validation of the simulator, it was observed the gel equivalence of filling of the polymer box required to reach the image parameters of the cataloged radiographs. The results are discussed as to the physical principles of radiation interaction with biological and equivalent tissues.

    The digital transformation of hospitals in Australia is occurring rapidly in order to facilitate innovation and improve efficiency. Rapid transformation can cause temporary disruption of hospital workflows and staff as processes are adapted to the new digital workflows. The aim of this paper is to outline various types of digital disruption and some strategies for effective management. A large tertiary university hospital recently underwent a rapid, successful roll-out of an integrated electronic medical record (EMR). We observed this transformation and propose several digital disruption "syndromes" to assist with understanding and management during digital transformation: digital deceleration, digital transparency, digital hypervigilance, data discordance, digital churn and post-digital 'depression'. These 'syndromes' are defined and discussed in detail. Successful management of this temporary digital disruption is important to ensure a successful transition to a digital platform. What is known about this topic? Digital disruption is defined as the changes facilitated by digital technologies that occur at a pace and magnitude that disrupt established ways of value creation, social interactions, doing business and more generally our thinking. Increasing numbers of Australian hospitals are implementing digital solutions to replace traditional paper-based systems for patient care in order to create opportunities for improved care and efficiencies. Such large scale change has the potential to create transient disruption to workflows and staff. Managing this temporary disruption effectively is an important factor in the successful implementation of an EMR. What does this paper add? A large tertiary university hospital recently underwent a successful rapid roll-out of an integrated electronic medical record (EMR) to become Australia's largest digital hospital over a 3-week period. We observed and assisted with the management of several cultural, behavioural and

    With the high speed development of digital signal process, the technique of the digitization and processing of signals was applied in the domain of a broad class of nuclear technique. The development of digital positron lifetime spectrometer (DPLS) is more promising than the conventional positron lifetime spectrometer equipped with nuclear instrument modules. And digital lifetime spectrometer has many advantages, such as low noise, long term stability, flexible online or offline digital processing, simple setup, low expense, easy to setting, and more physical information. Digital constant fraction discrimination is for timing. And a new method of optimizing energy windows setting for digital positron lifetime spectrometer is also developed employing the simulated annealing for the convenient use. The time resolution is 220ps and the count rate is 200cps. (authors)

    2001-12-01

    There is a wide consensus among the feature film production studios that the Internet era brings a new paradigm for film distribution to cinemas worldwide. The benefits of digital cinema to both producers and cinemas are numerous: significantly lower distribution and maintenance costs, immediate access to film libraries, higher presentation quality, and strong potential for developing new business models. Despite these advantages, the studios are still reluctant to jump into the digital age. The main showstopper for digital cinema is the danger of widespread piracy. Piracy already costs Hollywood an estimated two billion dollars annually and digital cinema without proper copyright enforcement could increase this number. In this paper, we present a copyright management system that aims at providing the set of necessary security tools: standard cryptographic primitives and copyright protection mechanisms that enable a reliable and secure feature film delivery system.

    1991-01-01

    With the access to digital methods for handling and processing images in general, many medical imaging methods are becoming more effectively handled digitally. This applies in particular to basically digital techniques such as CT and MR but also now includes Nuclear Medicine (NM), Ultrasound (US) and a variety of radiological procedures such as Digital Subtraction Angiography (DSA) and Fluoroscopy (DF). The access to conventional projection images by stimulatable plates (CR) or by digitization of film makes all of radiology potentially accessible, and the management of such images by a network is the basic aim of Picture Archiving and Communication Systems (PACS). However, it is suggested that in order for such systems to be of greater value, that way in which such images are treated needs to change, that is, digital images can be used to derive additional clinical value by appropriate processing

    Digitization of fluoroscopic images has been developed for the digital cine imaging system as a result of the computer technology, television technology, and popularization of interventional radiology. Present digital cine imaging system is able to offer images similar to cine film because of the higher operatability and better image quality with the development of interventional radiology. As a result, its higher usefulness for catheter diagnosis examination except for interventional radiology was reported, and the possibility of having filmless cine is close to becoming a reality. However several problems have been pointed out, such as spatial resolution, time resolution, storage and exchangeability of data, disconsolidated viewing functions, etc. Anyhow, digital cine imaging system has some unresolved points and lots the needs to be discussed. The tendency of digitization is the passage of the time and we have to promote a study for more useful digital cine imaging system in team medical treatment which centers on the patients. (author)

    2013-01-01

    This book serves a dual purpose: firstly to combine the treatment of circuits and digital electronics, and secondly, to establish a strong connection with the contemporary world of digital systems. The need for this approach arises from the observation that introducing digital electronics through a course in traditional circuit analysis is fast becoming obsolete. Our world has gone digital. Automata theory helps with the design of digital circuits such as parts of computers, telephone systems and control systems. A complete perspective is emphasized, because even the most elegant computer architecture will not function without adequate supporting circuits. The focus is on explaining the real-world implementation of complete digital systems. In doing so, the reader is prepared to immediately begin design and implementation work. This work serves as a bridge to take readers from the theoretical world to the everyday design world where solutions must be complete to be successful.

    The nuclear industry has been slow to incorporate digital sensor technology into nuclear plant designs due to concerns with digital qualification issues. However, the benefits of digital sensor technology for nuclear plant instrumentation are substantial in terms of accuracy and reliability. This paper, which refers to a final report issued in 2013, demonstrates these benefits in direct comparisons of digital and analog sensor applications. Improved accuracy results from the superior operating characteristics of digital sensors. These include improvements in sensor accuracy and drift and other related parameters which reduce total loop uncertainty and thereby increase safety and operating margins. An example instrument loop uncertainty calculation for a pressure sensor application is presented to illustrate these improvements. This is a side-by-side comparison of the instrument loop uncertainty for both an analog and a digital sensor in the same pressure measurement application. Similarly, improved sensor reliability is illustrated with a sample calculation for determining the probability of failure on demand, an industry standard reliability measure. This looks at equivalent analog and digital temperature sensors to draw the comparison. The results confirm substantial reliability improvement with the digital sensor, due in large part to ability to continuously monitor the health of a digital sensor such that problems can be immediately identified and corrected. This greatly reduces the likelihood of a latent failure condition of the sensor at the time of a design basis event. Notwithstanding the benefits of digital sensors, there are certain qualification issues that are inherent with digital technology and these are described in the report. One major qualification impediment for digital sensor implementation is software common cause failure (SCCF).

    The widespread use of digital media (both computing devices and the services they access) has blurred the boundaries between our personal and professional lives. Contemporary students are the last to remember a time before the widespread use of the Internet and they will be the first to practice in a largely e-health environment. This article explores concepts of digital professionalism and their place in contemporary medical education, and proposes a series of principles of digital professionalism to guide teaching, learning and practice in the healthcare professions. Despite the many risks and fears surrounding their use, digital media are not an intrinsic threat to medical professionalism. Professionals should maintain the capacity for deliberate, ethical, and accountable practice when using digital media. The authors describe a digital professionalism framework structured around concepts of proficiency, reputation, and responsibility. Digital professionalism can be integrated into medical education using strategies based on awareness, alignment, assessment, and accountability. These principles of digital professionalism provide a way for medical students and medical practitioners to embrace the positive aspects of digital media use while being mindful and deliberate in its use to avoid or minimize any negative consequences.

    Until recently, all film digitizing devices for use with teleradiology or picture archiving and communication systems used a video camera to capture an image of the radiograph for subsequent digitization. The development of film digitizers that use a laser beam to scan the film represents a significant advancement in digital technology, resulting in improved image quality compared with video scanners. This paper discusses differences in resolution, efficiency, reliability, and the cost between these two types of devices. The results of a modified receiver operating characteristic comparison study of a video scanner and a laser scanner manufactured by the same company are also discussed

    2008-07-01

    This book is meant for the radiologist who is facing the challenge of organizing a digital mammographic imaging center. This text is meant to be a practical book that provides information about digital mammographic physics and equipment which will allow one to intelligently compare technologies and systems. Some of the major challenges include: large expense; rapidly changing technology, and inconsistent connectivity; and finally, need for strong information technology support. The initial conversion cost to digital mammographic imaging is relatively expensive due to the cost of digital mammography hardware, software, and storage. Virtually all other imaging modalities are being converted to purely digital storage and transfer, and the digital trend in mammography is inevitable. Technical advantages of digital mammography are described. However, the improved flexibility in image display and transfer are some of its strongest features. In conclusion, although there are increasing imaging modalities that may be used to evaluate breast disease, mammography will continue to play a key role in detecting breast cancer. To be an effective imager, the radiologist should become familiar with digital mammography and understand its role within the increasing complex structure of breast imaging techniques.

    Objective: To assess revascularization and vessel anastomosis in digital replantations with DSA. Methods: Twelve cases of digital replantations underwent digital subtract angiography during 2 to 4 days after fingers reattachment. The vessel anastomosis, hemodynamics, stenosis and discontinuation were investigated. The unobstructed and smooth anastomosis was suggested as early stage survival of the reattached fingers, the spasm and stenosis of the reattached vessels were considered as mild vascular crisis, and the discontinuation of hemodynamics were indicated as severe vascular crisis. Results: The total 27 vessels were clearly displayed on DSA. Of these vessels, 23 vessels were unobstructed and smooth, all digits were survived. Diagnosis coincidence of early stage survival was 100% (23/23). Two vessels were obstructed, which were testified having thrombus by operation research. The other 2 vessels were spasm, the digits were also survived ultimately by expectant treatment. All 4 abnormal vessel anatomosis were found by DSA. Conclusion: DSA is important modality in assessing revascularization and blood circulation for digital replantations, guiding in dealing with the vascular crisis, and in predicting early stage survival of the reattached digits.

  18. Digital mineral logging system

    International Nuclear Information System (INIS)

    West, J.B.

    1980-01-01

    A digital mineral logging system acquires data from a mineral logging tool passing through a borehole and transmits the data uphole to an electronic digital signal processor. A predetermined combination of sensors, including a deviometer, is located in a logging tool for the acquisition of the desired data as the logging tool is raised from the borehole. Sensor data in analog format is converted in the logging tool to a digital format and periodically batch transmitted to the surface at a predetermined sampling rate. An identification code is provided for each mineral logging tool, and the code is transmitted to the surface along with the sensor data. The self-identifying tool code is transmitted to the digital signal processor to identify the code against a stored list of the range of numbers assigned to that type of tool. The data is transmitted up the d-c power lines of the tool by a frequency shift key transmission technique. At the surface, a frequency shift key demodulation unit transmits the decoupled data to an asynchronous receiver interfaced to the electronic digital signal processor. During a recording phase, the signals from the logging tool are read by the electronic digital signal processor and stored for later processing. During a calculating phase, the stored data is processed by the digital signal processor and the results are outputted to a printer or plotter, or both

Há uma suposição de que os jovens tendem a preferir a leitura digital ao suporte papel, porém pode não ser uma verdade absoluta, conforme atestam outras pesquisas (PewResearch Center, 2014. Com base em dados desses estudos, bem como na aplicação de testes em alunos do ensino médio, o presente trabalho parte do pressuposto de que o nível de percepção dos leitores pode ser relativamente diferente conforme o suporte utilizado. Para tanto, utilizamos como metodologia a aplicação de um teste de leitura em vinte e nove alunos, que leram textos curtos, com um ou dois parágrafos, em um suporte digital, tablet, e responderam a questões de compreensão sobre tais textos; repetindo o procedimento com outros textos em suporte papel. A hipótese era de que os alunos apresentassem modos diferentes de compreensão textual de acordo com o suporte utilizado. A análise dos dados coletados revelou um resultado sutilmente superior na compreensão dos textos impressos, porém insuficiente para ser generalizado como resultado conclusivo, não deixando, entretanto, de apontar caminhos significativos para a compreensão das práticas leitoras na escola.

    The potentially lucrative wireless market has led to technological advances in mixed signal devices such as high speed, high resolution A/D and D/A converters. This same market has also driven the development of high performance multi-channel digital receiver and digital transmitter ICs. Similarly, advances in semiconductor processes, coupled with the need for reduced time-to-market, has led to the development of large, enhanced performance, in-circuit programmable logic devices. A review of the key characteristics of these mixed-signal, signal processing and programmable logic devices is presented. The application of these devices and technologies to the instrumentation of Accelerators and Storage Rings is discussed and presented by way of examples. Issues relating to the requirements associated with real-time processing, I/O throughput, reconfigurability, reliability, maintainability and packaging requirements are also addressed

    DEFF Research Database (Denmark)

    Marton, Attila; Kallinikos, Jannis

    The structure of social memory is in a process of significant change as social operations of forgetting and remembering are increasingly written in IT and mediated in digital media. Based on an in-depth case study about the digitalization of memory institutions (libraries, archives, museums......), the paper demonstrates the emergence of a digital social memory structure that stores data as a means of forgetting. Building on such a concept, we explain the shifting structure of social memory from pre-defined, taxonomic order to algorithmic computation of artefacts and ordering. Finally, we draw...... implications from our study with regards to core organizational concepts of institutions and platforms as well as broader categories of information infrastructures and a sociology of digital knowledge....

  20. Digital pulse shape discrimination

    International Nuclear Information System (INIS)

    Miller, L. F.; Preston, J.; Pozzi, S.; Flaska, M.; Neal, J.

    2007-01-01

    Pulse-shape discrimination (PSD) has been utilised for about 40 years as a method to obtain estimates for dose in mixed neutron and photon fields. Digitizers that operate close to GHz are currently available at a reasonable cost, and they can be used to directly sample signals from photomultiplier tubes. This permits one to perform digital PSD rather than the traditional, and well-established, analogous techniques. One issue that complicates PSD for neutrons in mixed fields is that the light output characteristics of typical scintillators available for PSD, such as BC501A, vary as a function of energy deposited in the detector. This behaviour is more easily accommodated with digital processing of signals than with analogous signal processing. Results illustrate the effectiveness of digital PSD. (authors)

    2017-01-01

    Siemens MAMMOMAT Inspiration with Tomosynthesis enhances the diagnostic precision in mammographic screening. The apparatus has a wide-angle tomosynthesis up to 50 degrees. The Siemens breast augmentation algorithm reconstructs multiple two-dimensional breast images into three-dimensional images at the lowest doses to help detect tumors hidden from the overlapping chest tissue, allowing for a more accurate diagnosis than standard 2-dimensional digital mammography, and reducing the number of false positive results. 3D digital tomosynthesis improves the precision of detecting and diagnosing a larger number of expansive lesions, ensures better morphological mass analysis and architectural distortion, and detecting calcifications by adding digital breast tomosynthesis to the traditional two-dimensional digital mammogram of the patient. In this way, it solves the problem of overlapping parenchyma, reduces the number of unnecessary biopsies from questionable sonomammographic findings, and the need for stressful repeating procedures, which usually contributes to both better patient outcomes and cost saving.

  8. Digital radiology. Clinical experience

    Energy Technology Data Exchange (ETDEWEB)

    Stacul, F; Smathers, R L

    1985-01-01

    The authors report the experience achieved ad the Stanford University (USA) with a digital radiography system which allows the digitization of the film and of the images collected with photostimulable phophors. The phophor is essentially an intensifying screen where a latent image is stored after exposure to X-rays and is extracted by a laser scanning. The images collected with the digitized film and with the phophor (chest, breast, bone) have been analyzed. The digitized film offers potential diagnostic advantages over the conventional film, because of the contrast manipulation and many other processing options. The possibility to recover the information of overexposed films appears very attractive. The photostimulable phophors allow to get good quality images, with a consistent reduction of dose and costs. These plates offer the possibility, in the next future, to replace the conventional screen-film systems.

    Full Text Available Digital literature is a complex assemblage of related elements –material, spatial, linguistic, performative, textual, cultural, social– each of which is at one time interdependent and detached. This article discusses the literary creation within the cyberculture from the performativity point of view in relation to the textual apparatus. This is done through the analysis of a selection of performances where physical corporeality has a collaborative function with the body to a greater or lesser degree. Therefore, this physical feature can not only change, but stand at three possible and hybridizable axes: 1 the digital text as protagonist, 2 the digital text as counterpart, and 3 the digital text as site.

    Neuwirth, J. Jr.; Bohutova, J.

    1987-01-01

    The quality of radiodiagnostic methods to a great extent depends on the quality of the resulting image. The basic technical principles are summed up of the different parts of digital subtraction angiography apparatus and of methods of improving the image. The instrument is based on a videochain consisting of an X-ray tube, an intensifier of the radiographic image, optical parts, a video camera, an analog-to-digital converter and a computer. The main advantage of the digitally processed image is the possibility of optimizing the image into a form which will contain the biggest amount of diagnostically valuable information. Described are the mathematical operations for improving the digital image: spatial filtration, pixel shift, time filtration, image integration, time interval differentation and matched filtering.

  14. Digital Actuator Technology

    Energy Technology Data Exchange (ETDEWEB)

    Ken Thomas; Ted Quinn; Jerry Mauck; Richard Bockhorst

    2014-09-01

    There are significant developments underway in new types of actuators for power plant active components. Many of these make use of digital technology to provide a wide array of benefits in performance of the actuators and in reduced burden to maintain them. These new product offerings have gained considerable acceptance in use in process plants. In addition, they have been used in conventional power generation very successfully. This technology has been proven to deliver the benefits promised and substantiate the claims of improved performance. The nuclear industry has been reluctant to incorporate digital actuator technology into nuclear plant designs due to concerns due to a number of concerns. These could be summarized as cost, regulatory uncertainty, and a certain comfort factor with legacy analog technology. The replacement opportunity for these types of components represents a decision point for whether to invest in more modern technology that would provide superior operational and maintenance benefits. Yet, the application of digital technology has been problematic for the nuclear industry, due to qualification and regulatory issues. With some notable exceptions, the result has been a continuing reluctance to undertake the risks and uncertainties of implementing digital actuator technology when replacement opportunities present themselves. Rather, utilities would typically prefer to accept the performance limitations of the legacy analog actuator technologies to avoid impacts to project costs and schedules. The purpose of this report is to demonstrate that the benefits of digital actuator technology can be significant in terms of plant performance and that it is worthwhile to address the barriers currently holding back the widespread development and use of this technology. It addresses two important objectives in pursuit of the beneficial use of digital actuator technology for nuclear power plants: 1. To demonstrate the benefits of digital actuator

Selection processes shape the evolution of information ecosystems in which conventions are established for the ways in which information is used. The conventions determine norms for information friction and information quality as well as the sources of information and channels used. Digital information reduces information friction, often dramatically, and changes information quality. The increasing use of analytics in business increasingly delivers predictive or prescriptive digital information. These changes are happening faster than information ecosystem conventions can change. The relationships established in the paper enable an analysis of, and guide changes to, these conventions enabling a more effective use of digital information.

    Full Text Available These days dakwah is not only interpreted as transformation of a pure religious value, but also transformation of a more relevant value including many aspects in digital era. Digital era is when society succumbed into the flow of information causing cultural shock and difficulties on synthesizing meaning from those scattered information. Dakwah on Digital age must accommodate societal needs which tend to move into a mass society. It results in strategy and more humane and innovative dakwah methods. One of innovative dakwah methods is conducted dakwah activities through digital media,with the consequences of this is that da’i must developed soft skill and technological capabilities. Another beneficial comes from this is that dakwah could become more modern and practical in terms of methods and material. On the other hand, citizen Journalism as a mass cultural product and the results of technological development, gives an opportunity for da’i to able to record the entire activities, including the dynamics of islamic life. In terms of learning curriculum, dakwah in digital format must be included, so then the intellectual and cultural spirit which flourished in pesantren could be adapted and competed in a global world.

  18. Digital radiography in NDT applications

    2004-01-01

    A lot of film radiography could be replaced by today's technologies in the field of digital radiography. Only few of these applications have indeed replaced film. The choice to go digital depends on cost, quality requirement, workflow and throughput. Digital images offer a lot of advantages in terms of image manipulation and workflow. But despite the many advantages, a lot of considerations are needed before someone can decide to convert his organization from conventional to digital radiography. This paper gives an overview of all different modalities that can be used in digital radiography with today's technologies, together with the experiences of the pioneers of digital radiography. Film Scanning, Computed Radiography and Digital Radiography by using of different kinds of flat panel detectors all have their specific application fields and customers. What is the status of the technology today, which advantages brings digital radiography, and which are the limitations radiographers have to consider when replacing film by digital systems. (author)

    2003-05-01

    The Motion Picture Industry began a transition from film based distribution and projection to digital distribution and projection several years ago. Digital delivery and presentation offers the prospect to increase the quality of the theatrical experience for the audience, reduce distribution costs to the distributors, and create new business opportunities for the theater owners and the studios. Digital Cinema also presents an opportunity to provide increased flexibility and security of the movies for the content owners and the theater operators. Distribution of content via electronic means to theaters is unlike any of the traditional applications for video compression. The transition from film-based media to electronic media represents a paradigm shift in video compression techniques and applications that will be discussed in this paper.

    Digital Radiography is a big part of diagnostic radiology. Because uncorrected digital radiography image supported false effect of Patient’s health care. We must be manage the correct digital radiography image. Thus, the artifact images can have effect to make a wrong diagnosis. We report types of occurrence by analyzing the artifacts that occurs in digital radiography system. We had collected the artifacts occurred in digital radiography system of general hospital from 2007 to 2014. The collected data had analyzed and then had categorize as the occurred causes. The artifacts could be categorized by hardware artifacts, software artifacts, operating errors, system artifacts, and others. Hardware artifact from a Ghost artifact that is caused by lag effect occurred most frequently. The others cases are the artifacts caused by RF noise and foreign body in equipments. Software artifacts are many different types of reasons. The uncorrected processing artifacts and the image processing error artifacts occurred most frequently. Exposure data recognize (EDR) error artifacts, the processing error of commissural line, and etc., the software artifacts were caused by various reasons. Operating artifacts were caused when the user did not have the full understanding of the digital medical image system. System artifacts had appeared the error due to DICOM header information and the compression algorithm. The obvious artifacts should be re-examined, and it could result in increasing the exposure dose of the patient. The unclear artifact leads to a wrong diagnosis and added examination. The ability to correctly determine artifact are required. We have to reduce the artifact occurrences by understanding its characteristic and providing sustainable education as well as the maintenance of the equipments.

  11. Digital Receiver Phase Meter

    Marcin, Martin; Abramovici, Alexander

    2008-01-01

    The software of a commercially available digital radio receiver has been modified to make the receiver function as a two-channel low-noise phase meter. This phase meter is a prototype in the continuing development of a phase meter for a system in which radiofrequency (RF) signals in the two channels would be outputs of a spaceborne heterodyne laser interferometer for detecting gravitational waves. The frequencies of the signals could include a common Doppler-shift component of as much as 15 MHz. The phase meter is required to measure the relative phases of the signals in the two channels at a sampling rate of 10 Hz at a root power spectral density measurements in laser metrology of moving bodies. To illustrate part of the principle of operation of the phase meter, the figure includes a simplified block diagram of a basic singlechannel digital receiver. The input RF signal is first fed to the input terminal of an analog-to-digital converter (ADC). To prevent aliasing errors in the ADC, the sampling rate must be at least twice the input signal frequency. The sampling rate of the ADC is governed by a sampling clock, which also drives a digital local oscillator (DLO), which is a direct digital frequency synthesizer. The DLO produces samples of sine and cosine signals at a programmed tuning frequency. The sine and cosine samples are mixed with (that is, multiplied by) the samples from the ADC, then low-pass filtered to obtain in-phase (I) and quadrature (Q) signal components. A digital signal processor (DSP) computes the ratio between the Q and I components, computes the phase of the RF signal (relative to that of the DLO signal) as the arctangent of this ratio, and then averages successive such phase values over a time interval specified by the user.

    2014-05-01

    Full Text Available Urban landscapes that exist in the expression of an imaginative sequence define their shape through the digital representation. These hyperreal dimensions, combine imagination and representation as constituents a new reality, which follows the utopian, suprematist and constructivist theories, where the two-dimensional dynamics is transformed into an infinite space in which the imagination creates new forms. Although interpretations of the urban landscape film, put in place a correspondence between reality and virtuality, into the modeling of spatial movements, from which do not arise contraries, but only interdependencies. It is a particular type of representation that takes shape via the digital in motion and provides new tools for urban representation.

    In digital breast tomosynthesis a digital tomographic data set with a very high spatial resolution is reconstructed from low-dose projections collected over a limited rotation angle. This allows a very detailed assessment of e. g. masses and architectural distortions. The average glandular dose is comparable to 2 D mammography. First clinical studies demonstrated that tomosynthesis is able to supply important additional information in suspicious mammographic findings. In comparison to projection mammography, tomosynthesis shows an at least comparable diagnostic accuracy. In everyday practice, tomosynthesis is currently mostly used for further evaluation of suspicious findings in mammography.

    This paper reports on the value of contrast post processing with DLR (2.5 lp/mm; gray-scale, 10 bit) evaluated in myelography (decision making depends more on image contrast than on spatial resolution). DLR was compared with conventional myelography by means of ROC methodology. Ninety-five conventional (CR), digital (DR), and edge- enhanced digital (EDR) myelographic images (49 disk herniations, 46 normal) were read independently by five board-certified radiologists with no clinical information. Findings were scored using a 5-point confidence-scale, and an ROC analysis was performed based on CT-myelography as the gold standard
