    The scope of a computerized system is presented to make an energy diagnosis to homes and a simulation of scenarios of cost/benefit, due to the implementation of energy saving measures and the efficient use of electrical energy. The FIPATERM (trust for the heat insulation of the house in Mexicali), provides economic and technical support so that the domestic users diminish their expense for the electrical energy, implementing programs of Demand Side Management (DSM). The current effective programs are: thermal insulation, substitution of the existent air conditioning units for efficient ones, reduction of infiltration, leveled plan of payments, interruption of the air conditioning equipment. In order to participate in one or several of the programs of energy efficiency, an energy diagnosis is made to the user. It is from a survey of the equipment and characteristics of the house, as well as a description on the part of the user of his habits of use of the equipment, that scenarios are simulated, which allow the user to identify the most profitable measures. [Spanish] Se presenta el alcance de un sistema computarizado para realizar diagnostico energetico a casas habitacion y simulacion de escenarios de beneficio/costo, debido a la implantacion de medidas de ahorro y uso eficiente de energia electrica.

Esse tipo de avaliação representa importante ferramenta para desenvolver estratégias de gestão para o setor. Objetivo: identificar fatores e avaliar diferenças regionais do grau de satisfação dos usuários do sistema de saúde brasileiro, analisando os resultados da Pesquisa Mundial de Saúde (PMS e Pesquisa Mundial de Saúde com foco na Atenção Básica (PMS-AB. Foi realizado estudo avaliativo de corte transversal, onde as amostras foram selecionadas de forma aleatória. Foram incluídas pessoas maiores de 18 anos que utilizaram o sistema de saúde em períodos anteriores às coletas de dados. Enquadraram-se nos critérios de inclusão 3.932 usuários da PMS e 591 da PMS-AB. Aplicou-se modelo logístico multivariado, tendo como variável dependente a satisfação e, como variáveis independentes, sexo, idade, escolaridade, forma de pagamento de serviço, situação conjugal, autopercepção de saúde, doença de longa duração, diagnóstico de depressão, tristeza, número de moradores por domicílio, tipo de construção, estratos geográficos e indicador de bens. Os resultados revelaram que ser jovem, usuário exclusivo do SUS, ter baixa escolaridade e autopercepção de saúde ruim gerou mais chances de insatisfação dos usuários com o sistema de saúde brasileiro. Os moradores da Região Sul do país estão mais satisfeitos com o atendimento em saúde, enquanto para pernambucanos as chances de satisfação são menores quando se avalia a qualidade dos serviços de saúde. Os moradores desse estado apresentaram maior insatisfação na resolução de seus problemas de saúde quando precisaram de internação.Developing evaluation models of satisfaction that allow comparing health systems in different countries is a recent effort in Brazil.

    The on-line systems for the management of the Laguna Verde Central (CLV) have had the challenge to evolve from the PC's of first generation until emigrate to the new Internet technologies, so that they allow to the diverse work groups to have the computer tool that allows them to gather the necessary data and to carry out efficiently the analysis of their results. To confront the previous challenge, in the CLV it has been developed and implemented the Nucleo Red that is an on-line system with the objective of providing in it lines strategic information for the Technician-administrative management of the plant in the nuclear context. The Nucleo Red is the computational tool that reflects the technical administrative processes implemented by personnel of the different Operative departments, it seeks to cooperate to the reliable and efficient operation of the first nucleo electric central of Mexico, with technology and Mexican personnel the one which already it had received international recognitions. The perspective of this computer system is to continue inside the process of continuous improvement and that although it was designed for a nucleo electric plant it can also be taken to the conventional plants of generation of electric power, so that this technology can be taken advantage of in other non nuclear facilities. The objective of the present work, is to show the new modules that have been developed in the Nucleo Red, its operation in general, and the benefits that it presents its use. (Author)

    The project involves the use of a compatible microcomputer, Labwindows/CVI software, as well as National Instruments data acquisition cards AT-MIO16-E10 and PC-DIO96 to modify the sequence of movement of the reactor's rods and control them from a graphic interface in a computer's monitor. This graphic presentation is set as console of virtual instruments from where rod movement can be conducted. Normal rod movement, bank rod movement, and rod calibration have been considered. These experiences involve different logic of rod movements, which will determine movement sequence. Control of the automatic range of a current amplifier module was also considered. This module is know as 'automatic pilot amplifier' and given the strategic location of its detector (compensated ionizing camera) at the reactor's core, it delivers neutron flux current considered as reference to superficial neutron flux distribution at the reactor's core. Lecture and monitoring of this signal allows taking the reactor to a certain power, current of this signal is proportional to the power we want the reactor to reach. Advantages obtained with this system include the update of the control console, more uniform distribution of neutron flux, with lower and uniform burnup of nuclear fuel. (author)

    Often, the rotary equipment faults appear as an abnormal vibration or a change in the characteristic vibration pattern of each machine. From here the importance of counting on tools that allow to acquire and to analyze the vibration signals of the equipment while it is in operation. The Gerencia de Turbomaquinaria has worked in this field since the end of the Seventies, developing diagnosis systems based on personal computers that allow the monitoring of the dynamic behavior of the rotary equipment. The main system of this type that the Instituto de Investigaciones Electricas (IIE), nowadays offers, is the Computerized System for Dynamic Analysis, also known by its abbreviation in Spanish as: SICAD II. This was designed under the requirements of the Comision Federal de Electricidad (CFE) to collect, measure and analyze vibration data of rotary equipment. It is also used in the balance, fault diagnosis and the solution of problems in rotary equipment. The system SICAD II is portable and versatile system with which vibrations are acquired, measured and analyzed by means of the presentation of the data in graphical formats of different type and application.

    Apesar das pesquisas com sistemas silvipastoris terem sido iniciadas no final da década de 1970, as informações geradas até hoje não são em grande número. As vantagens advindas de um sistema silvipastoril são inúmeras e devidamente reconhecidas. Pelo fato de ser uma técnica de uso da terra capaz de recuperar ecossistemas alterados pelo mau manejo, estes sistemas, pela integração de atividades agrícolas, pecuárias e silviculturais, passam a representar uma tecnologia que confere maior sustentabilidade que os sistemas tradicionais, nos quais os monocultivos são predominantes. Nos últimos anos, instituições de ensino, pesquisa e extensão do País têm se voltado para o desenvolvimento de tais sistemas. O governo de Minas Gerais, por meio de sua Secretaria de Estado de Agricultura e de órgãos vinculados, vem promovendo a condução de modelos agrossilvipastoris num processo integrado de ocupação do solo, denominado lavoura-pecuária-silvicultura. Apesar dos grandes avanços no conhecimento de culturas anuais e dos componentes arbóreos, principalmente o eucalipto, e de gramíneas forrageiras tolerantes à diminuição da intensidade luminosa, ainda é necessário se comnhecer melhor o manejo do sub-bosque sob os efeitos do pastejo.

    The Instituto Nacional de Investigaciones Nucleares (ININ) has a nuclear research reactor type swimming pool with movable core cooled and moderate with light water. The nominal maximum power of the reactor is 1 MW in steady-state operation and can be pulsed at a maximum power of 2,000 MW for approximately 10 milliseconds. This reactor is mainly used to study the effects of radiation on various materials and substances. In 2001 the new control console of the nuclear reactor was installed which was based on two digital computers, one computer controls the bar management mechanisms and the other the systems to the reactor operator. In 2004, the control computer was replaced and the software was updated. Within the modernization and/or updating of the TRIGA Mark III reactor of ININ, is intended (theme of this work) to develop the user interface for the visualization of the auxiliary systems, through a Man-Machine Interface module for the renewal process of the control console. The man-machine interface system to be developed will have communication with the programmable logic controllers that will be constantly monitored and controlled to obtain real-time variables of the reactor behavior.

São focalizadas a paracoccidioidose e a criptococose. Depois de caracterizarem clìnicamente a paracoccidioidose, acentuam a raridade das formas nervosas (1,2% dos casos dessa micose autopsiados no Departamento de Anatomia Patológica da Faculdade de Medicina da Universidade de São Paulo. Pela revisão da literatura foi verificado haver apenas 12 casos registrados. 0 caso de Casiello e Klass é o único em que o diagnóstico foi feito em vida; os demais, ou constituem achado de necropsia, ou foram inesperadamente revelados pelo exame histopatológico realizado após intervenções cirúrgicas. Os autores registram 2 casos de paracoccidioidose do sistema nervoso. No primeiro, tratava-se de meningomielorra-diculite crônica, sendo o parasito identificado no escarro; o segundo era portador de síndrome de compressão medular, cuja patogenia é discutida pelos autores, tendo sido a etiologia paracoccidióidica comprovada pelo exame da polpa e biópsia ganglionares. Considerações clínicas sôbre a criptococose precedem o relato de um caso de meningoencefalomielite subaguda, no qual fôra feito em vida o diagnóstico de paracoccidioidose, pelo exame micológico do liqüido cefalorraqueano; êste paciente, embora medicado com doses maciças de sulfa e tiossemicarbarsona, veio a falecer, tendo o exame anátomo-patológico revelado tratar-se, na realidade, de lesões nervosas produzidas pelo Crypíococcus neo-formans.

    Full Text Available As micoses do sistema nervoso central não têm merecido atenção cuidadosa dos neurologistas. Elas afetam o neuraxe em diferente percentagem: a granulomatose criptocóccica (torulose é a mais freqüente, seguindo-se a actinomicose; a granulomatose paracoccidióidica só excepcionalmente determina lesões meningoencefálicas. Do ponto de vista clínico, as neuromicoses podem ser divididas em duas formas: tumorais encefalomedulares e meningíticas. Estas predominam sobre as tumorais, das quais são mais freqüentes as de localização encefálica. Não são raros os quadros mistos, meningoencetálicos. As formas tumorals encefálicas abrangem vários tipos anátomo-patológicos - abscesso, granuloma, nódulos e cistos - sendo mais comuns os dois primeiros, todos êles produzindo o quadro clinico da síndrome hipertensiva intracraniana. As formas meningomedulares, em geral, são secundárias às lesões ósseas vertebrais, sendo a actinomicose, por ser a mais osteófila, a micose que mais freqüentemente atinge a medula. Nestes casos, o quadro clínico da síndrome compressiva é o mais comum. As meninges participam do processo fúngico, na maior parte dos casos; as manifestações clínicas variam desde o simples meningismo, até as meningites purulentas e meningoencefalites graves, havendo a possibilidade de se formarem aracnoidites císticas, ependimites e bloqueios ventriculares, do aqueduto ou mesmo do canal raquidiano. O diagnóstico das micoses do sistema nervoso central é comumente um "achado de autópsia". Somente a verificação do cogumelo no líquor e o seu isolamento permitem um diagnóstico seguro. Outros dados liquóricos, quando bem interpretados com os achados clínicos e neurológicos, orientam o analista na pesquisa do agente fúngico. O quadro anátomo-patológico nada tem de caraterístico, a não ser a presença do agente parasitário e só o seu encontro firma o diagnóstico. Examinamos 25 casos de granulomatose

Para ello se hizo una revisión de conceptos referentes a la integración de la actividad forestal en la ganadería, como alternativa viable de sistema de producción. Se parte del criterio de que los sistemas silvopastoriles (SSP, dentro de los agroforestales, son agroecosistemas en los que se asocia un componente arbóreo con uno herbáceo (pasturas naturales o mejoradas y otro pecuario (ganado en un mismo sitio, donde existen interacciones biológicas entre estos y se maximiza el uso de la tierra. También se describe cómo se agrupan los SSP; sus oportunidades desde los puntos de vista económico, productivo, social y ambiental; y los efectos de la interacción entre sus componentes. Este análisis permite plantear que los SSP son producto de la relación entre la biología, la sociedad y la cultura, y en ellos existe una enorme diversidad; asimismo, permiten la reconversión de la ganadería extensiva de muy baja productividad en sistemas más productivos y sostenibles en el tiempo, así como la rehabilitación de las áreas degradadas por ese tipo de ganadería, por la deforestación y por el agotamiento de los suelos.

En un sistema se da un conjunto de unidades interrelacionadas de tal manera que el comportamiento de cada parte depende del estado de todas las otras, pues todas se encuentran en una estructura que las interconecta. En el enfoque sistémico, el concepto tradicional de energía es reemplazado por el de información, y el de causa-efecto por el de estructura y realimentación. El deporte es una realidad social total, por lo que participa de manera implícita y/o explícita en los procesos humanos más diversos a través de los distintos procedimientos que corresponden a nuestra organización sociocultural. El deporte se configura en estructuras de alta complejidad, las cuales están constituidas por sistemas de sistemas cuya comprensión y estudio representan un formidable reto. El estudio del deporte como sistema debe efectuarse desde la lógica estructural y sistémica a través de la cual nos permita indagar con éxito su configuración esencial, sus elementos fundamentales y el proceso de interactuación con los subsistemas que pertenecen al sistema deporte y con los otros del sistema sociocultural dominante. El deporte es un sistema dinámico que interactúa continuamente mediante un doble proceso, intrínseco a través de una constante metamorfosis entre los distintos subsistemas que lo integran y extrínseco por medio de un ajuste permanente con el contexto social, cultural y medioambiental.

    El sistema inmune recibe señales del sistema nervioso central (cerebro) vía el sistema nervioso autónomo y el sistema endocrino. El sistema inmune, a su vez, envía información al cerebro vía citocinas. Este sistema de retroalimentación es vital para el funcionamiento adecuado del organismo en situaciones normales, y en aquellas en las que la homeostasis se ve perturbada, como en casos de estrés, consumo de drogas (terapéuticas o de abuso), enfermedades infecciosas y...

    Full Text Available La psiconeuroinmunología es una nueva parcela de la ciencia que apenas lleva tres décadas, pero que en los últimos años ha sido objeto de una enorme atención por diversos grupos de investigación. El articulo pretende exponer brevemente cómo están organizados los sistemas inmune y neuroendocrino, para después presentar los hallazgos que hasta el momento intentan dar explicación de las relaciones entre ambos con el sistema nervioso, así como las influencias de unos sobre otros, más concretamente expresar la relación entre los tres sistemas responsables de la defensa del organismo y, más ampliamente, de su mantenimiento homeostático. Cuando se trata de amenazas, el sistema nervioso central tiene que decidir qué sistema se pone en marcha, el sistema de estrés como energía para el ataque o la huida (un animal que nos quiere atacar, el sistema inmune para neutralizar el antígeno (un virus que nos quiere atacar o ambos (la energía es necesaria también para el sistema inmune. Como parece ser que en muchas ocasiones la depresión aparece tras los esfuerzos infructuosos de puesta en marcha de estrategias de afrontamiento, también hemos repasado sucintamente algunas investigaciones que relacionan al sistema inmune con la depresión, así como con los trastornos del sueño. Se finaliza con las aportaciones que la psicología puede ofrecer a nivel terapéutico.

    Full Text Available Resumen: En este artículo se propone un observador distribuido garantista para sistemas en red, considerando de forma explícita el problema de los retardos variables en las comunicaciones. Se asume que la información intercambiada entre agentes llega siempre a su destino, si bien las comunicaciones están sujetas a retardos variables, cuyo valor máximo se supone conocido. Cada observador trabaja con información parcial, y necesita comunicarse con observadores vecinos para llevar a cabo una estimación del estado completo del sistema. Para representar a los conjuntos garantistas, cuya función es acotar en tiempo real la región en la que se encuentra el estado del sistema, se ha optado por la utilización de zonotopos. Esto permite integrar de forma sencilla la información recibida por cada agente. Finalmente se presentan resultados de simulación para validar el algoritmo propuesto. Abstract: This paper proposes a guaranteed distributed observer for networked systems, taking into account the problem of the variable delays in communications. We assume that the information exchanged among the agents always arrives to its destination, although the communication are subject to variable delays, whose maximum value is known. Each observer works with partial information, and needs to communicate with neighbouring observers to carry out an estimation of the complete state of the system. The guaranteed sets, whose function is to delimit in real time the region in which the state of the system belong to, are represented by zonotopes. This kind of sets allows a simple integration of the information received by each agent. Finally some results obtained with the proposed algorithm are shown in simulations.

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

    1992-01-01

    The user interface (UI) of HYPGEN is developed using Panel Library to shorten the learning curve for new users and provide easier ways to run HYPGEN for casual users as well as for advanced users. Menus, buttons, sliders, and type-in fields are used extensively in UI to allow users to point and click with a mouse to choose various available options or to change values of parameters. On-line help is provided to give users information on using UI without consulting the manual. Default values are set for most parameters and boundary conditions are determined by UI to further reduce the effort needed to run HYPGEN; however, users are free to make any changes and save it in a file for later use. A hook to PLOT3D is built in to allow graphics manipulation. The viewpoint and min/max box for PLOT3D windows are computed by UI and saved in a PLOT3D journal file. For large grids which take a long time to generate on workstations, the grid generator (HYPGEN) can be run on faster computers such as Crays, while UI stays at the workstation.

  1. Implicit User Interest Profile

    CERN Document Server

    Chan, K

    2002-01-01

    User interest profile presents items that the users are interested in. Typically those items can be listed or grouped. Listing is good but it does not possess interests at different abstraction levels - the higher-level interests are more general, while the lower-level ones are more specific. Furthermore, more general interests, in some sense, correspond to longer-term interests, while more specific interests correspond to shorter-term interests. This hierarchical user interest profile has obvious advantages: specifying user's specific interests and general interests and representing their relationships. Current user interest profile structures mostly do not use implicit method, nor use an appropriate clustering algorithm especially for conceptually hierarchical structures. This research studies building a hierarchical user interest profile (HUIP) and the hierarchical divisive algorithm (HDC). Several users visit hundreds of web pages and each page is recorded in each users profile. These web pages are used t...

    ção/registro dos exames complementares básicos - e propiciem melhor utilização do pré-natal pelas pacientes.PURPOSE: to evaluate the adequacy of the prenatal care process offered to users of the Unified Health Care System (SUS in Juiz de Fora-MG and to compare the municipal services. METHODS: a transversal study with auditing was carried out on the records of 370 pregnant women, selected by systematic sampling among women who carried their pregnancies to term and gave birth using SUS services in the first semester of 2002, with prenatal care given in Juiz de Fora. For statistical analysis the c² test was used to compare the municipal services (level of significance: 5%. The evaluation followed a three-tiered complementary sequence, using: the utilization of prenatal care (Kessner index: beginning and frequency of care at level 1; the utilization of prenatal care and basic laboratory tests, according to the Humanization Program of Prenatal Care and Birth (ABO-Rh, hemoglobin/hematocrit, VDRL, glycemia and urinalysis, at level 2; and the utilization of prenatal care, the basic laboratory tests and the obligatory clinical-obstetric procedures during a prenatal visit (assessment of blood pressure, weight, edema, uterine fundal height, gestational age, fetal heart rate and fetal presentation, at level 3. RESULTS: the observed adequacy of the process was only 26.7% (level 1, 1.9% (level 2 and 1.1% (level 3. We also observed a prenatal coverage of 99.04%, an average of 6.4 visits per pregnant woman, and an average gestational age of 17.4 weeks at the time of the first prenatal visit. There were no significant differences between the municipal services. CONCLUSIONS: prenatal care offered to SUS users in Juiz de Fora should be reviewed from a qualitative standpoint, and periodic evaluations as necessary instruments of improvement are recommendable. Managers and professionals should undertake actions aimed at increasing compliance with norms/routines of the program - principally the

    Una de las formas de estudiar la existencia de caos en el comportamiento de un sistema clásico-cuántico, es truncando el espacio de Hilbert del sistema cuántico. El objetivo de este trabajo es analizar como afecta dicho truncamiento en la dinámica del sistema. Para tal fin se propone un Hamiltoniano integrable, cuyos valores de expectación asociados a coordenadas y momentos cuánticos responden, por el teorema de Ehrenfest, a un sistema de dos osciladores clásicos con acoplamiento lineal.

    Full Text Available Tentando consolidar as noções de totalidade, a geografia física passa a utilizar a noção de sistemas dinâmicos, não lineares e de comportamento caótico. Deste modo, a abordagem sistêmica/complexa apresenta-se como meio de compreensão do mundo natural, assim possibilitando a previsão de mudanças, avaliação dos sistemas ambientais, distúrbios e limiares do sistema. Nota-se, assim, a importância dos estudos processuais para o gerenciamento de recursos hídricos, tornando imprescindíveis estudos sistêmicos que analisem os diversos elementos importantes para a análise dos recursos hídricos, dentre eles as questões processuais. Deste modo, a necessidade de se trabalhar o gerenciamento integrado de recursos hídricos, enquadrado na perspectiva sistêmica, solidificou a bacia hidrográfica e/ou bacia de drenagem como recorte espacial sistêmico. Delimitada a área pode-se compreender a bacia hidrográfica como um Sistema Fluvial, conceituado por Schumm (1977, que é analisado a partir da zona fonte de sedimentos, da rede de transporte e dos sítios de deposição. Esses elementos não são espacialmente excludentes, interagindo entre si, além de apresentar escalas diferenciadas. Para o estudo do sistema fluvial é necessário levar em consideração quatro conceitos: uniformidade dos processos, limiares de mudança, evolução da paisagem e respostas complexas.

    The simplification philosophy, as an example, that both of EPRI-URD and EUR emphasize is treated mostly for the cost reduction of the nuclear power plants, but not for the simplification of the structure of user's tasks, which is one of the principles of user-centered design. A user-centered design is a philosophy based on the needs and interests of the user, with an emphasis on making products usable and understandable. However, the nuclear power plants offered these days by which the predominant reactor vendors are hardly user-centered but still designer-centered or technology-centered in viewpoint of fulfilling user requirements. The main goal of user-centered design is that user requirements are elicited correctly, reflected properly into the system requirements, and verified thoroughly by the tests. Starting from the user requirements throughout to the final test, each requirement should be traceable. That's why requirement traceability is a key to the user-centered design, and main theme of a requirement management program, which is suggested to be added into EPRI-URD and EUR in the section of Design Process.

Sendo assim, uma solução seria desenvolver alternativas que auxilie no tratamento do esgoto, e que ainda satisfaça as necessidades da população. Portanto, a implantação de um sistema de tratamento de esgoto doméstico seria a alternativa ideal, pois garante um baixo custo de construção e uma excelente eficiência, minimizando assim grande parte dos problemas. Desse modo, com o  dimensionamento de um sistema composto por Fossa Séptica e Sumidouro para uma residência de pequeno porte é possível descrever suas funções e como é realizado o projeto através da norma NBR 7229/1993.

  5. Selección de Canales en Sistemas BCI basados en Potenciales P300 mediante Inteligencia de Enjambre

    Directory of Open Access Journals (Sweden)

    2017-10-01

    Full Text Available Resumen: Los sistemas Brain-Computer Interface (BCI se definen como sistemas de comunicación que monitorizan la actividad cerebral y traducen determinadas características, correspondientes a las intenciones del usuario, en comandos de control de un dispositivo. La selección de canales en los sistemas BCI es fundamental para evitar el sobre-entrenamiento del clasificador, reducir la carga computacional y aumentar la comodidad del usuario. A pesar de que se han desarrollado varios algoritmos con anterioridad para tal fin, las metaheurísticas basadas en inteligencia de enjambre aún no han sido suficientemente explotadas en los sistemas BCI basados en potenciales P300. En este estudio se muestra una comparativa entre cinco métodos de enjambre, basados en el comportamiento de sistemas biológicos, aplicados con el objetivo de optimizar la selección de canales en este tipo de sistemas. Los métodos se han evaluado sobre la base de datos de la “III BCI Competition 2005”, reportando precisiones similares o, en algunos casos, incluso más altas que las obtenidas sin realizar ningún tipo de selección. Dado que los cinco métodos se han demostrado capaces de disminuir drásticamente los 64 canales originales a menos de la mitad sin comprometer el rendimiento del sistema, así como de superar el conjunto típico de 8 canales y el método backward elimination, se concluye que todos ellos son adecuados para su aplicación en la selección de canales en sistemas P300-BCI. Abstract: Brain-Computer Interfaces (BCI are direct communication pathways between the brain and the environment that translate certain features, which correspond to users’ intentions, into device control commands. Channel selection in BCI systems is essential to avoid over-fitting, to reduce the computational cost and to increase the users’ comfort.

    Full Text Available The conventional functions of a library are to gather, process, broadcast, store and use the documental information to provide service to the society. And this definition can also be applied in the context of the digital age, where the work of the professionals of the information and documentation is daily related to the use of the available resources through Internet. Although the definition of Digital Library includes a wider term, the present article it will refer to the group of digital resources. Internet is the biggest encyclopedia in the world, but the information is not available in an orderly way and it is not easy to obtain. Although the users, librarians and documentalists have tools as search engines to locate the information, the way we obtain the results is decisive in order to their suitable exploitation. The traditional orderly list of references can loose its effectiveness when the number of obtained documents is very high. In this article, we show several available techniques and developments on visualization systems in the information retrieval in Internet. These systems use elements in two or three dimensions, and it will allow that users, librarians and documentalists have the feeling of moving among the recovered information as they would do in a surface or in the space.

    Las funciones convencionales de una biblioteca son reunir, procesar, difundir, almacenar y usar la información documental para dar servicio a la sociedad.

    Solar linear concentration technologies to generate high temperatures are limited to the ranges of 200 to 500 degrees Celsius. While its performance has been tested through prototypes and pilot plants around the world, there are still areas of opportunity that can be exploited to obtain a linear concentration that achieves temperatures above this range in order to have a better use of the available solar energy. Because of this: It is possible to develop a linear concentration system that can track the sun with minimal movement of the absorber-receiver while maintaining temperatures above 850 degrees Celsius sufficient for industrial processes that require that temperature. The methodology consists of a series of stages (conceptual design, simulation, evaluation, development concept, results and validation) through which concepts are generated that allow design and evaluation of solar concentrator configurations with the help of simulation software. We have designed a linear parabolic concentrating system which comprises a set of mirrors segments with different focal lengths that works within the range of 600 degrees Celsius; however, it is advancing in the development of a double concentration to reach 850 degrees Celsius. [Spanish] Las tecnologias de concentracion lineal solar para generar altas temperaturas se ven limitadas a los rangos de 200 a 500 grados centigrados. Si bien su funcionamiento ha sido probado a traves de prototipos y plantas piloto alrededor del mundo, aun existen areas de oportunidad que pueden ser aprovechadas para obtener un sistema de concentracion lineal que permita alcanzar temperaturas mayores a este rango para asi tener un mejor aprovechamiento de la energia solar disponible. Debido a esto: Es posible desarrollar un sistema de concentracion lineal capaz de seguir la trayectoria del Sol con minimo movimiento del absorbedor-recibidor al mismo tiempo que mantiene temperaturas superiores a los 850 grados centigrados suficientes para

    Full Text Available User frustrations are an excellent source of new product ideas. Starting with this observation, this article describes an approach that entrepreneurs can use to discover business opportunities. Opportunity discovery starts with a problem that the user has, but may not be able to articulate. User-centered design techniques can help elicit those latent needs. The entrepreneur should then try to understand how users are solving their problem today, before proposing a solution that draws on the unique skills and technical capabilities available to the entrepreneur. Finally, an in-depth understanding of the user allows the entrepreneur to hone in on the points of difference and resonance that are the foundation of a strong customer value proposition.

  5. User interface support

    Lewis, Clayton; Wilde, Nick

    1989-01-01

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

    This document describes the PANTHER R&D Application, a proof-of-concept user interface application developed under the PANTHER Grand Challenge LDRD. The purpose of the application is to explore interaction models for graph analytics, drive algorithmic improvements from an end-user point of view, and support demonstration of PANTHER technologies to potential customers. The R&D Application implements a graph-centric interaction model that exposes analysts to the algorithms contained within the GeoGraphy graph analytics library. Users define geospatial-temporal semantic graph queries by constructing search templates based on nodes, edges, and the constraints among them. Users then analyze the results of the queries using both geo-spatial and temporal visualizations. Development of this application has made user experience an explicit driver for project and algorithmic level decisions that will affect how analysts one day make use of PANTHER technologies.

    Full Text Available Muchas de las empresas modernas entendieron que sus antiguas unidades de sistemas ya no son funcionales, y comienzan a subdividirlas en dos grupos de trabajo diferenciadores: el encargado de la infraestructura y el de los denominados “arquitectos de Sistemas”. Esta decisión lógica la inspira la actual evolución de la Ingeniería de Sistemas que, como área de conocimiento, genera los mismos subgrupos como agentes para formación. Además, la evolución y complejidad de lossistemas de información en medio de la sociedad del conocimiento, con exigencias y expectativas muy complejas, también determinan la necesidad de esta especialización.

    Satellite communication systems which allow a multitude of user-to-user, point-to-point, and multipoint connections, are presented. The bit rates are 64 kbit/sec and multiples, up to 1.92 Mbit/sec. If required, the ground-stations are installed at the customer's site or at suitable locations in order to serve several customers. However, technical requirements for station location have also to be fulfulled, in order to avoid interference with terrestrial radio services. The increasing number of participants to Satellite Multi Service and INTELSAT Business Services imposes the solution of the problem of communication using cheap techniques. The changes of the German Federal Post Office also permit the economic use of satellite radio techniques for short distances.

    In order to facilitate and to simplify the development and analysis of a Hybrid System in reference to its design, construction, operation and maintenance, it turns out optimal to carry out the simulation of this one by means of software, with which a significant reduction in the investment costs is obtained. Given the mix of technology of electrical generation which is involved in a hybrid system, it is very important to have a tool integrated with specialized packages of calculation (software), that allow to carry out the simulation tasks of the operational functioning of these systems. Combined with the former, one must not fail to consider the operation characteristics, the facilities of the user, the clarity in the obtained results and the possibility of its validation with respect to prototypes orchestrated in field. Equally, it is necessary to consider the identification of tasks involved in relation to the place of installation of this electrification technology. At the moment, the hybrid systems technology still is in a stage of development in the international level, and exist important limitations as far as the methodology availability and engineering tools for the optimum design of these systems. With the development of this paper, it is intended to contribute to the advance of the technology and to count on own tools to solve the described series of problems. In this article are described the activities that more impact have in the design and development of hybrid systems, as well as the identification of variables, basic characteristics and form of validation of tools in the integration of a methodology for the simulation of these systems, facilitating their design and development.

A 3D electronic model is generated through the user interface of the design system that at the same time gives the user the ability to generate, publish, review and control the engineering document that are generated during the entire life cycle of a marine oil platform, a very particular type of industrial process plant. This way, the user obtains not only a tool for the design of an industrial plant, but also a system for managing information and engineering documents that are developed. This allows the user to do a more efficient job by putting at his disposal and in the same system, all documents and information required to perform his duty.

    Full Text Available El envejecimiento del sistema cardiovascular está asociado con un número característico de cambios a nivel bioquímico, histológico y morfológico. Sin embargo, no todas las modificaciones presentadas se asocian con deterioro en la función. Entre los cambios a nivel cardiaco se tienen: disminución en el número de miocitos y en las células del sistema de conducción cardiaca, desarrollo de fibrosis, cambios en el transporte de calcio a través de las membranas y disminución del cronotropismo, inotropismo y lusitropismo mediados por estímulo b-adrenérgico. A nivel vascular, hay incremento en la rigidez de la pared de las arterias, con aumento en la velocidad de la onda de pulso, disfunción endotelial y disminución de la vasodilatación mediada por estímulo b-adrenérgico. Durante el reposo el sistema cardiovascular es capaz de desarrollar mecanismos adaptativos eficientes, pero en situaciones de estrés como el ejercicio, los cambios asociados con el envejecimiento se hacen evidentes ya que está disminuida la capacidad para obtener la frecuencia cardiaca máxima, está incrementada la postcarga y hay disminución de la contractilidad intrínseca. Por lo anterior, los ancianos deben utilizar al máximo el mecanismo de Frank-Starling para mantener el gasto cardiaco. Los cambios estructurales y funcionales asociados con el envejecimiento cardiovascular, disminuyen de forma significativa el umbral en el cual las enfermedades cardiacas llegan a ser evidentes, y deben ser conocidos por el personal de salud encargado de cuidar a los ancianos.Cardiovascular aging is associated with characteristic biochemical, histological and morphological changes. Nevertheless, these changes are not necessarily associated to a deterioration in its function.

    Full Text Available A suinocultura caracteriza-se como uma atividade de alto impacto ambiental, devido a grande quantidade de dejetos com alta carga de poluentes, lançados no meio ambiente. No entanto, existem diversas tecnologias, e sistemas de tratamento, com a capacidade de reduzir o poder poluente dos dejetos da suinocultura. O presente trabalho tem como objetivo analisar as principais tecnologias e sistemas de tratamentos para os dejetos da suinocultura, presentes em publicações brasileiras. Os resultados obtidos nestas publicações apresentaram-se de certa forma satisfatórios em relação à redução da carga de poluentes dos efluentes da suinocultura. Entretanto, pouco se sabe sobre o comportamento da redução dos poluentes em função de parâmetros dimensionais e temporais das tecnologias ou dos sistemas de tratamento. Tal desconhecimento dificulta o dimensionamento de sistemas de tratamento, desconsiderando a relação existente entre investimento e redução do poder poluente dos dejetos. Dentro deste contexto, a modelagem e otimização de sistemas pode ser uma ferramenta muito útil para o dimensionamento de tecnologias e sistemas de tratamento de dejetos de suínos.

    SISTEMA Project has been funded by the PO FESR 2007-2013 action, supported by the Campania Region (Italy). The project fosters the integrated use of multidisciplinary data in order to improve the understanding of the volcanic processes at Campi Flegrei and Ischia and to progress in science and surveillance of the territory according to the rationale of Supersite GEO initiative to Campi Flegrei, currently identified as Permanent Supersite. The mission of SISTEMA is to upgrade the existing monitoring and surveillance systems through the design, purchase and installation of new instrumentation, equipment, technology and methods addressing the need of delivering, with improved rapidity, scientific information for decision makers and end-users. The redundancy of monitoring systems is an important issue to guarantee the full operability during emergencies. The Monitoring Centre of INGV-Osservatorio Vesuviano is currently located within the red zone (potentially at risk of invasion by pyroclastic flows in case of eruption) of Campi Flegrei volcano. Its position offers various logistic benefits but at the onset of a volcanic crisis, of course it will be required to shift this Center in a safer area. For this reason, within the SISTEMA project, we envisioned a backup system which, when needed, could guarantee a shift of the Center in a virtually zero time. This can be achieved by fully duplicating the processing system and the data storage. In case of emergency, it would be required only to switch on the visualization systems in the new Center and transferring the personnel involved in the surveillance activities. SISTEMA project has also enabled the development of a permanent GPS and CRs (Corner Reflectors) networks, the latter supporting SAR Interferometry, by helping to improve knowledge of the Campi Flegrei deformation field, both on local and wide scale. In addition, in order to enhance the heat flux measurements from ground based thermal camera observations, the

The description is based on the experimental use of STAIRS at the IAEA computer, with INIS and AGRIS data bases, from June 1975 to May 1976. Special attention is paid to what may be termed the hierarchical approach to retrieval in STAIRS. Such an approach allows for better use of the intrinsic data-base structure and, hence, contributes to higher recall and/or relevance ratios in retrieval. The functions carried out by STAIRS are explained and the communication language between the user and the system outlined. Details are given of the specific structure of the INIS and AGRIS data bases for STAIRS. The manual should enable an inexperienced user to start his first on-line dialogues by means of a CRT or teletype terminal. (author)

    Jay, Caroline; Lunn, Darren; Michailidou, Eleni

    As new technologies emerge, and Web sites become increasingly sophisticated, ensuring they remain accessible to disabled and small-screen users is a major challenge. While guidelines and automated evaluation tools are useful for informing some aspects of Web site design, numerous studies have demonstrated that they provide no guarantee that the site is genuinely accessible. The only reliable way to evaluate the accessibility of a site is to study the intended users interacting with it. This chapter outlines the processes that can be used throughout the design life cycle to ensure Web accessibility, describing their strengths and weaknesses, and discussing the practical and ethical considerations that they entail. The chapter also considers an important emerging trend in user evaluations: combining data from studies of “standard” Web use with data describing existing accessibility issues, to drive accessibility solutions forward.

Dentre as atividades agropecuárias, os sistemas agroflorestais (SAF têm sido considerados como sustentáveis, apresentando-se como alternativas aos sistemas intensivos de produção. Para monitorar a sustentabilidade de atividades agropecuárias em geral, incluindo os SAF, diferentes autores enfatizam os indicadores biofísicos, em detrimento dos socioeconômicos. Com o objetivo de definir um rol de indicadores socioeconômicos adaptáveis aos diversos modelos de SAF, desenvolveu-se um estudo consolidado por recomendações de especialistas e ampla revisão de literatura. Concluiu-se que: as categorias relacionadas com a operação dos sistemas comportaram o maior número de indicadores no componente socioeconômico, com maior concentração nas operações endógenas ao sistema, seguidas, de longe, pelos recursos endógenos e exógenos; o maior número de indicadores, sugeridos na categoria operação do sistema, deu-se nos descritores saúde e nutrição, empregos, habitação e saneamento básico e análise econômica; na categoria operação de sistemas exógenos, determinou-se maior número de indicadores para os descritores comercialização e infra-estrutura rural; praticamente, não houve diferença entre o número de indicadores obtidos para os sistemas agroflorestais com e sem o componente animal.

Instead of assigning reasons for the users information behavior of users, we search to understand their motivations and perceptions. Therefore, we tried to enter the universe of users by writing in-depth semi-structured interviews to collect data. Results. The research generated good comprehensive and descriptive results, bringing relevant considerations about SIEX/UFMG and extension at the University. Conclusions. The survey revealed that the use of SIEX / UFMG goes beyond its basic functions and allows us to understand the users' perception regarding the university extension.

    This paper explores an architecture for very long term user modelling, based upon personal user model clouds. These ensure that the individual's applications can access their model whenever it is needed. At the same time, the user can control the use of their user model. So, they can ensure...... which combines both. Finally we discuss implications of our approach for consistency and freshness of the user model information....... it is accessed only when and where they wish, by applications that they wish. We consider the challenges of representing user models so that they can be reused by multiple applications. We indicate potential synergies between distributed and centralised user modelling architectures, proposing an architecture...

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

    Johnson, Sally C.; Boerschlein, David P.

    1994-01-01

    Semi-Markov models can be used to analyze the reliability of virtually any fault-tolerant system. However, the process of delineating all of the states and transitions in the model of a complex system can be devastatingly tedious and error-prone. Even with tools such as the Abstract Semi-Markov Specification Interface to the SURE Tool (ASSIST), the user must describe a system by specifying the rules governing the behavior of the system in order to generate the model. With the Table Oriented Translator to the ASSIST Language (TOTAL), the user can specify the components of a typical system and their attributes in the form of a table. The conditions that lead to system failure are also listed in a tabular form. The user can also abstractly specify dependencies with causes and effects. The level of information required is appropriate for system designers with little or no background in the details of reliability calculations. A menu-driven interface guides the user through the system description process, and the program updates the tables as new information is entered. The TOTAL program automatically generates an ASSIST input description to match the system description.

Desde la perspectiva de la administración, hay casos de autogobierno en que los regantes mismos realizan todas las tareas con base en sistemas de conocimiento local, otros en que toda la administración se encuentra a cargo de personal contratado. Hay casos de administración burocrática y tecnocrática en sistemas con distinto locus de autoridad (Estado/regantes. Además, se propone que mientras el autogobierno de sistemas de riego no parece tener límites de tamaño, la administración sin burocracia ni persona l especializado parece estar acotada a sistemas de riego de una extensión determinada. No obstante, se argumenta que el gobierno influye sobre el carácter de la administración, dado que su descentralización disminuye o evita que sea burocrática/tecnocrática.

El sistema es caracterizado por una semántica de valuaciones tradicionales con la cual se prueba que, respecto al operador de negación débil, el sistema es paraconsistente. Como es de esperarse, cuando las fórmulas involucradas en un argumento se comportan clásicamente, es decir, son incompatibles con su negación débil, entonces la negación débil se comporta como la negación clásica, pero este requisito no siempre es necesario, la negación débil puede ser puntualmente tan potente como la clásica, aunque las fórmulas involucradas no se comporten clásicamente.The language of the LBPc¬I system extends the language of the classical positive logic when including an operator of weak negation and an operator of incompatibility, and permit to define an operator of strong negation; this last one has all the characteristics of the classical negation. The system is characterized by a traditional semantics with which test that, with respect to the operator of weak negation, the system is paraconsistent. When the formulas involved in an argument behave classically, that is to say, are incompatible with his weak negation, then the weak negation behaves like the classical negation, but this requirement not always is necessary, the weak negation can precise be as powerful as the classical negation although the involved formulas do not behave classically.

  13. Métodos de control en sistemas domóticos: últimas tendencias en sistemas distribuidos

    Directory of Open Access Journals (Sweden)

    Moreno Navarro, I.

    1999-02-01

    Full Text Available Control systems lie amongst the most difficult issues to be tackled when it comes to designing home automation systems. Two classical tendencies may be considered to solve this problem. The first one consists of a centralised control system, whereas the second option advocates for a distributed network, where piece would take up certain responsibilities in the control of the whole system. In this paper we analyse some of the latest developments as regards programming distributed networks, focusing on home automation, specially Java and the latest Jini environments have dramatically improved the potential of such kind of distributed systems, thanks to them, it is possible to build a heterogeneous network including devices from different brands which work in collaborative systems, thus avoiding complex configurations.

    Uno de los aspectos más delicados a la hora de diseñar un sistema domótico es el que se refiere al modelo de control que deseamos establecer. Podemos considerar dos tendencias clásicas: la que trata de establecer un control centralizado del sistema y la que propone un control mucho más descentralizado, donde cada aparato seria responsable de cierta parte de la gestión del control ejercido sobre toda la red. En este articulo tratamos de profundizar en las últimas novedades aparecidas en el campo de la programación de los controladores asociados a una red domótica, en particular Java y el más reciente Jini, que aportan una serie de soluciones que facilitan la compatibilidad entre dispositivos de distintos fabricantes y apuestan claramente por una arquitectura de tipo distribuido, dotando a las redes domóticas de una flexibilidad y un potencial de crecimiento inusitados.

  14. Control lineal robusto de sistemas no lineales diferencialmente planos

    Directory of Open Access Journals (Sweden)

    Hebertt Sira-Ramirez

    2011-01-01

    Full Text Available Resumen: En este trabajo se proponen controladores basados en observadores lineales para el control robusto de una clase amplia de sistemas no lineales conocidos como sistemas diferencialmente planos, sean estos monovariables o multivariables. Se establece primeramente el modelo dinámico entrada - salida plana, simplificándolo a un modelo de carácter no fenomenológico que solamente considera como elementos claves en el diseño del controlador el orden de integración del sistema y el factor de ganancia de entrada, en el caso monovariable, y, los órdenes de los subsistemas de integración de Kronecker y la matriz de ganancias del vector de entradas en el caso multivariable. El resto de las no linealidades, dependientes del estado o de naturaleza exógena, son consideradas, en general, como perturbaciones desconocidas pero acotadas que toman valores en el tiempo. Se demuestra que estas perturbaciones son algebraicamente observables, permitiendo su determinación aproximada mediante observadores lineales de orden arbitrario. Estos observadores, llamados observadores GPI, incluyen modelos internos que representan polinomios en el tiempo, cuya actualización es de índole automática, permitiendo aproximaciones arbitrariamente cercanas a las perturbaciones desconocidas. El diseño del controlador se reduce entonces a lograr la cancelación de las perturbaciones aditivas a la vez de imponer una dinámica lineal en lazo cerrado mediante realimentación de estados estimados, los cuales se obtienen directamente del mismo observador lineal propuesto. Se presenta un ejemplo de simulación que considera un sistema físico no lineal de complejidad reconocida. También se incluyen resultados experimentales sobre dos prototipos de laboratorio.

    Identifying online user reputation is significant for online social systems. In this paper, taking into account the preference physics of online user collective behaviors, we present an improved group-based rating method for ranking online user reputation based on the user preference (PGR). All the ratings given by each specific user are mapped to the same rating criteria. By grouping users according to their mapped ratings, the online user reputation is calculated based on the corresponding group sizes. Results for MovieLens and Netflix data sets show that the AUC values of the PGR method can reach 0.9842 (0.9493) and 0.9995 (0.9987) for malicious (random) spammers, respectively, outperforming the results generated by the traditional group-based method, which indicates that the online preference plays an important role for measuring user reputation.

  6. Sistemas Correctores de Campo Para EL Telescopio Cassegrain IAC80

    Galan, M. J.; Cobos, F. J.

    1987-05-01

    El proyecto de instrumentación de mayor importancia que ha tenido el Instituto de Astrofisica de Canarias en los últimos afios ha sido el diseflo y construcción del te1escopio IAC8O. Este requería del esfuerzo con junto en mec´nica, óptica y electrónica, lo que facilitó la estructuración y el crecimiento de los respectivos grupos de trabajo, que posteriormente se integraron en departamentos En su origen (1977), el telescopio IAC80 fue concebido como un sistema clásico tipo Cassegrain, con una razón focal F/i 1.3 para el sistema Casse grain y una razón focal F/20 para el sistema Coudé. Posteriormente, aunque se mantuvo la filosofia de que el sistema básico fuera el F/11.3, se consideró conveniente el diseño de secundarios para razones focales F/16 y F/32, y se eliminó el de F/20. Sin embargo, dada la importancia relativa que un foco estrictamente fotográfico tiene en un telescopio moderno, diseñado básicamente para fotometría fotoeléctrica y con un campo util mínimamente de 40 minutos de arco, se decídió Ilevar a cabo el diseño de un secundario F/8 con un sistema corrector de campo, pero que estuviera formado únicamente por lentes con superficies esféricas para que asl su construcción fuera posible en España ó en México. La creciente utilización de detectores bidimensionales para fines de investigación astron6mica y la viabilidad de que en un futuro cercano éstos tengan un área sensible cada vez mayor, hicieron atractiva la idea de tener diseñado un sistema corrector de campo para el foco primario (F/3), con un campo útil mínimo de un grado, y también con la limitante de que sus componentes tuvieron sólamente supérficies esféricas. Ambos diseños de los sis-temas correctores de campo se llevaron a cabo, en gran medida, como parte de un proyecto de colaboración e intercambio en el área de diseño y evaluación de sistemas ópticos.

    Strout, R.E. II; Beach, J.L.

    1977-01-01

    The GANDALF computer code was written to calculate neutron dose equivalent given the pulse-height data obtained by using a Linear Energy Transfer (LET) proportional counter. The code also uses pre- and/or post-calibration spectra, from an alpha source, to determine a calibration factor in keV/μ/channel. Output from the code consists of the effective radius of the detection chamber in microns, a calibration factor in keV/μ/channel, and the total dose and dose equivalent in rad or rem between any two LET energies by using the equations by Attix and Roesch [Radiation Dosimetry, 1, 71 (1968)]. This report is a user's manual and is not intended as anything else, and assumes that the user has a basic knowledge of the LLL Octopus timesharing system.

    TEBASCO is a Tandem mirror Equilibrium and BAllooning Stability COde. TEBASCO allows you to compute tandem-mirror MHD equilibria and to analyze both the flute-averaged and ballooning-mode stability of these equilibria. This stability analysis is directed toward the computation of marginal stability boundaries. Users of TEBASCO require a binary output file from the EFFI code which describes the vacuum magnetic field. In making this EFFI file the user will have defined a system of units for lengths (e.g., meters) and magnetic field (e.g., Tesla). In TEBASCO, all magnetic field strengths are normalized to the vacuum center-cell midplane value, and times are defined in units of the time for an Alfven wave in this field to transit one EFFI unit of length

It has been purposely designed to reduce the small-angle data collected on the ISIS small-angle neutron camera LOQ in an interactive and user-friendly manner. This not only gives the LOQ user an opportunity to inspect data rapidly and comprehensively during the course of an experiment but also provides the instrument scientists with a flexible diagnostic tool with which they can monitor the performance of the instrument. After the experiment is completed, COLETTE may be used to provide the final I(Q) versus Q following subtraction of a sample background run and normalisation to a scattering standard. By limiting the range of azimuthal angles included in the analysis the program may take sections through an anisotropic scattering pattern from an ordered system. A completely two dimensional I(Q x ,Q y ) map may also be generated. (author)

  10. Users' requirements for IFMIF

    1998-01-01

    The International Fusion Materials Irradiation Facility (IFMIF) is a high energy neutron irradiation facility which generates an intense neutron flux with D-Li stripping reactions for fusion materials testing. The role of IFMIF is (1) development of various fusion reactor materials, (2) determination of design-relevant engineering databases for the DEMO fusion reactor, (3) calibration and validation of data generated from fission reactor irradiations and the other simulation experiments, etc. The conceptual design activity (CDA) of IFMIF was initiated in February 1995 as an IEA collaborative activity to complete a reference conceptual design of IFMIF in December 1996. Users' requirements for the conceptual design of IFMIF were developed for materials to be tested, types of experiments, small specimen test technology and irradiation conditions. Furthermore, the neutron irradiation field characteristics (spectrum, flux/volume, etc.) of IFMIF were evaluated for the conceptual design parameters and were shown to meet the essential requirements of the users.

    2000-01-01

    This manual is a combination of a user manual, theory manual, and programmer manual. The reader is assumed to have some previous exposure to the finite element method. This manual is written with the idea that the CSTEM (Coupled Structural Thermal Electromagnetic-Computer Code) user needs to have a basic understanding of what the code is actually doing in order to properly use the code. For that reason, the underlying theory and methods used in the code are described to a basic level of detail. The manual gives an overview of the CSTEM code: how the code came into existence, a basic description of what the code does, and the order in which it happens (a flowchart). Appendices provide a listing and very brief description of every file used by the CSTEM code, including the type of file it is, what routine regularly accesses the file, and what routine opens the file, as well as special features included in CSTEM.

    Semi-Markov models can be used to analyze the reliability of virtually any fault-tolerant system. However, the process of delineating all the states and transitions in a complex system model can be devastatingly tedious and error prone. The Abstract Semi-Markov Specification Interface to the SURE Tool (ASSIST) computer program allows the user to describe the semi-Markov model in a high-level language. Instead of listing the individual model states, the user specifies the rules governing the behavior of the system, and these are used to generate the model automatically. A few statements in the abstract language can describe a very large, complex model. Because no assumptions are made about the system being modeled, ASSIST can be used to generate models describing the behavior of any system. The ASSIST program and its input language are described and illustrated by examples.

    User Interface Inspection Methods succinctly covers five inspection methods: heuristic evaluation, perspective-based user interface inspection, cognitive walkthrough, pluralistic walkthrough, and formal usability inspections. Heuristic evaluation is perhaps the best-known inspection method, requiring a group of evaluators to review a product against a set of general principles. The perspective-based user interface inspection is based on the principle that different perspectives will find different problems in a user interface. In the related persona-based inspection, colleagues assume the

    PARFUME, a fuel performance analysis and modeling code, is being developed at the Idaho National Laboratory for evaluating gas reactor coated particle fuel assemblies for prismatic, pebble bed, and plate type fuel geometries. The code is an integrated mechanistic analysis tool that evaluates the thermal, mechanical, and physico-chemical behavior of coated fuel particles (TRISO) and the probability for fuel failure given the particle-to-particle statistical variations in physical dimensions and material properties that arise during the fuel fabrication process. Using a robust finite difference numerical scheme, PARFUME is capable of performing steady state and transient heat transfer and fission product diffusion analyses for the fuel. Written in FORTRAN 90, PARFUME is easy to read, maintain, and modify. Currently, PARFUME is supported only on MS Windows platforms. This document represents the initial version of the PARFUME User Guide, a supplement to the PARFUME Theory and Model Basis Report which describes the theoretical aspects of the code. User information is provided including: (1) code development, (2) capabilities and limitations, (3) installation and execution, (4) user input and output, (5) sample problems, and (6) error messages. In the near future, the INL plans to release a fully benchmarked and validated beta version of PARFUME.

Although there is a growing interest on User Experience, there are still limited resources (i.e. measurement tools or questionnaires available to measure user experience of any products, especially learning management systems. Two hundreds and thirteen computer science students participated and completed the adapted version of UEQ. In the study, the researchers used a learning management system named Student Centered e-Learning Environment (SCELE. Several types of learning materials are posted in SCELE such as audio files, simulations, PowerPoint slides, multimedia contents, and webpage links. Most of the lecturers use discussion forums in their courses to encourage students to participate in active learning setting. Staff and lecturers sometimes post academic-related announcements on the SCELE homepage. Two hundred thirteen students enrolled in Computer Science program were invited to evaluate the SCELE. This study will benefit UX practitioners, HCI educators, program and center of learning resources administrators, and learning management system developers. Findings of the present study may also be valuable for universities and high schools which are using computer-based learning environments.

    This document details the use of the reliability code for the Atomic Vapor Laser Isotope Separation (AVLIS) project. This code was designed by Tom Anklam and John Harris. In late 1984 Patrick McGrady and Elena Koontz of C and TD/TA were assigned the task of improving the code and converting it for use on the DEC-10 system. In early 1986, Patric McGrady converted it to the CRAY. The AVRAM code is divided into distinct parts (often referred to as programs in this document). There is a COSMOS file that controls the execution of the FORTRAN code and controls the naming of output datasets and the deletion of temporary datasets created by the code. The FORTRAN code consists of a main program as a driver and of three main subroutines: EDIT, PARAM, and AVRAM. The EDIT program allows the user to create a new user defined system or add to an existing system or to change certain parameters. The PARAM program allows the user to alter system parameters and to select options such as economics run, criticality analysis or sensitivity studies. The AVRAM program does a reliability analysis of the system

O objetivo do presente estudo foi verificar se a alta aceitabilidade inicial do preservativo feminino, descrita em outros estudos, é mantida na rotina de atendimento às diferentes populações vulneráveis. Foram monitorados durante 12 meses 16 serviços do Sistema Único de Saúde da Grande São Paulo (7 serviços especializados em atendimento às doenças sexualmente transmissíveis, 6 unidades básicas de saúde e 3 projetos comunitários. Foram incluídas no estudo 2.469 mulheres, das quais 713 em serviços de atenção especializada às DST/Aids, 1.417 em unidades básicas e 339 em projetos comunitários. A análise da continuidade de uso foi realizada por tábua de sobrevida Kaplan-Meier, teste log-rank e modelo de regressão de Cox, com intervalo de confiança de 95% (IC=95%. Observou-se que, ao final do seguimento, estavam em uso contínuo do preservativo feminino 14,4% das mulheres (355. O tempo médio de uso foi de 3,55 meses (IC 95%: 3,37- 3,73. Os resultados evidenciaram que o tipo de serviço de dispensação do insumo e a frequência mensal de relações sexuais interferiram na continuidade de uso de forma estatisticamente significante.

    Full Text Available In order to survive, libraries must be able to adapt -flexibly, efficiently and responsively- to user needs. New technological developments serve to help libraries adjust to their new challenges and this is one of the reasons that leads them to migrate from one automated system to another. Implementing a new system is a complex process, owing to the new features being introduced and to the need to migrate data from the first system. This article analyzes why, how and when systems are changed, and includes guidelines for managing the transition: objectives, needs analyses, elaboration of technical specifications, and evaluation. Once the new system is chosen, the management of change begins and involves both the library management and library staff. Finally, the importance of staff participation in the entire process is discussed, including training and channels of communication.

    Las bibliotecas, para poder sobrevivir, han de adaptarse a las demandas de los usuarios, de una manera más flexible, sensible y eficaz. Los nuevos desarrollos tecnológicos ayudan a la biblioteca a adecuarse a sus nuevas necesidades, y es por ello por lo que más frecuentemente se produce el cambio de un sistema automatizado a otro. La implementación de un segundo sistema es un proceso más complejo, debido a las nuevas prestaciones que se incorporan y al tener que migrar los datos ya existentes en el primer sistema. En este artículo se analiza el por qué, el cómo y el cuándo del cambio de sistema, así como las líneas de actuación previas que se han de seguir antes de iniciar el cambio: objetivos, análisis de necesidades, definición de especificaciones técnicas y evaluación. Una vez elegido el producto, se inicia la gestión del cambio que involucra tanto a la dirección para que lo controle, como al personal que actúa como agente del cambio.

Es el caso del sistema endocanabinoide, involucrado en diversos fenómenos fisiológicos entre los que se encuentran el refuerzo de ciertos comportamientos y la regulación del apetito. La sobreactivación de este sistema altera la homeostasis corporal predisponiendo a dependencias o a un aumento en la ingesta alimentaria, lo que puede traducirse en tabaquismo u obesidad. La intervención farmacológica sobre el sistema endocanabinoide puede contribuir al manejo de estos factores de riesgo cardiovascular, teniendo en cuenta que a tales beneficios se suman otros independientes de la suspensión del tabaquismo o la reducción de peso, como el aumento del colesterol de alta densidad, la disminución de triglicéridos y la mejoría del control glucémico en pacientes con diabetes. Ensayos clínicos controlados aleatorizados adelantados en poblaciones con diferentes características, han evaluado la utilidad de la regulación farmacológica del sistema endocanabinoide; confirmando su eficacia en personas con factores de riesgo cardiovascular establecidos.

    Full Text Available O direito à saúde é objeto de constante análise e, a cada momento, visualiza-se a necessidade de enfrentar diferentes interfaces desse direito fundamental. A complexidade inerente ao sistema social, e, por conseguinte, ao da saúde também, demanda-nos romper com a classificação de cidadãos de primeira e de segunda classe; isso não é republicano, tampouco democrático. A lógica dos desumanizados e excluídos (esquecidos e negligenciados deve ser cambiada pela lógica da inclusão. A análise enfocará a saúde no sistema prisional. Para isso, é condição de possibilidade analisarmos os condicionantes de saúde e os seus efeitos no panorama prisional-sanitário brasileiro. Observaremos, ainda, as ações governamentais para efetivar o direito à saúde no sistema prisional, em especial a Política Pública de Saúde “Plano Nacional de Saúde no Sistema Penitenciário”, que se apresenta como uma tentativa concreta de romper com a negligência do Estado em relação aos integrantes do sistema prisional, aos esquecidos, aos sem voz. ABSTRACT The right to health is matter of constant analysis and, at each moment the need to challenge the different interfaces of this basic right is visible. The innate complexity of the social system and, by consequence to the health system as well, demands that we break with the concept of first and second class citizens; this is not republican or even democratic. The de-humanized and excluded logic (forgotten and neglected must be traded for the inclusion logic. The analysis will focus the prison system’s health. For this is condition of possibility to analyze the health conditions and its effects in the Brazilian prison-sanitary scope. We will also observe the government’s actions to make the right to heath effective in the prison system, in special the Public Health Policy “Nacional Health Plan in the Prison System”, which is presented as a real attempt to break with the state’s negligence

    Full Text Available This paper is concerned with urban parks and their use(rs. It focuses on usage-spatial relationships from two different angles. Firstly, it discusses the actual uses mapped in places, using repeated observation on different days, times and weather conditions. Secondly, it addresses designers’ views and beliefs about usage and design of urban parks. However, the paper shows that designers’ beliefs and awareness about uses in places, in some aspects, differ from actual use. It stresses the use of empirical knowledge about usage-spatial relationships, which can be gained by using observation and behavioural mapping, in decision-making processes for parks design.

  12. A User-Centric View of Intelligent Environments: User Expectations, User Experience and User Role in Building Intelligent Environments

    Directory of Open Access Journals (Sweden)

    Eija Kaasinen

    2012-12-01

    Full Text Available Our everyday environments are gradually becoming intelligent, facilitated both by technological development and user activities. Although large-scale intelligent environments are still rare in actual everyday use, they have been studied for quite a long time, and several user studies have been carried out. In this paper, we present a user-centric view of intelligent environments based on published research results and our own experiences from user studies with concepts and prototypes. We analyze user acceptance and users’ expectations that affect users’ willingness to start using intelligent environments and to continue using them. We discuss user experience of interacting with intelligent environments where physical and virtual elements are intertwined. Finally, we touch on the role of users in shaping their own intelligent environments instead of just using ready-made environments. People are not merely “using” the intelligent environments but they live in them, and they experience the environments via embedded services and new interaction tools as well as the physical and social environment. Intelligent environments should provide emotional as well as instrumental value to the people who live in them, and the environments should be trustworthy and controllable both by regular users and occasional visitors. Understanding user expectations and user experience in intelligent environments, and providing users with tools to influence the environments can help to shape the vision of intelligent environments into meaningful, acceptable and appealing service entities for all those who live and act in them.

    The results of a series of telephone interviews with groups of users of information on photovoltaics (PV) are described. These results, part of a larger study on many different solar technologies, identify types of information each group needed and the best ways to get information to each group. The report is 1 of 10 discussing study results. The overall study provides baseline data about information needs in the solar community. It covers these technological areas: photovoltaics, passive solar heating and cooling, active solar heating and cooling, biomass energy, solar thermal electric power, solar industrial and agricultural process heat, wind energy, ocean energy, and advanced energy storage. An earlier study identified the information user groups in the solar community and the priority (to accelerate solar energy commercialization) of getting information to each group. In the current study only high-priority groups were examined. Results from seven PV groups respondents are analyzed in this report: DOE-Funded Researchers, Non-DOE-Funded Researchers, Researchers Working for Manufacturers, Representatives of Other Manufacturers, Representatives of Utilities, Electric Power Engineers, and Educators.

    2001-01-01

    Personal computers (PCs) are now used extensively for engineering analysis. their capability exceeds that of mainframe computers of only a few years ago. Programs originally written for mainframes have been ported to PCs to make their use easier. One of these programs is ARDS (Analysis of Rotor Dynamic Systems) which was developed at Arizona State University (ASU) by Nelson et al. to quickly and accurately analyze rotor steady state and transient response using the method of component mode synthesis. The original ARDS program was ported to the PC in 1995. Several extensions were made at ASU to increase the capability of mainframe ARDS. These extensions have also been incorporated into the PC version of ARDS. Each mainframe extension had its own user manual generally covering only that extension. Thus to exploit the full capability of ARDS required a large set of user manuals. Moreover, necessary changes and enhancements for PC ARDS were undocumented. The present document is intended to remedy those problems by combining all pertinent information needed for the use of PC ARDS into one volume.

Based on a systematic literature review, this paper shows a detailed view on the broad variety...... of research on lead user characteristics, lead user processes, lead user identification and application, and success factors. The main challenge of the lead user method as identified in literature is the resource issue regarding time, manpower, and costs. Also, internal acceptance and the processing...... of the method have been spotted in literature, as well as the intellectual property protection issue. From the starting point of the initial lead user method process introduced by Lüthje and Herstatt (2004), results are integrated into a revisited view on the lead user method process. In addition, concrete...

    EURALERT-89 is a dose assessment program system including countermeasures which has been developed in the framework of the C.E.C. research programme 'Radiological aspects of nuclear accident scenarios'. For this purpose the ECOSYS model for calculating the transfer of radionuclides through the environment, the contamination of foodstuffs and potential doses has been adapted to real-time use in the different European countries. In this user's guide the file names are given in the form SUBD/FNAM; this means that the data file with name FNAM is in the subdirectory SUBD. Remember that writing the path of a file depends on the computer used. With EURALERT-89 it is relatively simple to get an estimate of the most important informations (deposition, maximum specific activities in foodstuffs, most important dose values) for all locations which are included in the input file. This goal can be achieved with only a few commands. (orig./HP)

    La Academia Nacional de Medicina de Colombia en repetidas ocasiones, desde el año 1998, ha denunciado las notables defi ciencias del Sistema General de Seguridad Social en Salud (SGSSS que implantó la Ley 100 de diciembre 23 de 1993. 

    El SGSSS, que debiera ser sistema de aseguramiento con propósito social, se ha convertido en negocio donde priman los intereses económicos con descuido en la calidad de los servicios; hizo profunda crisis, principalmente por causa de los excesivos costos que conlleva el modelo de intermediación comercial. Se ha creado una inaceptable posición oligopólica dominante de los aseguradores, que parece haber suplantado al estado en la defi nición de las políticas y en la orientación del SGSSS e interfiere la buena prestación de los servicios. Manifestación prominente de esto es la creciente y descontrolada integración vertical. 

    El sistema colombiano de intermediación comercial es costoso, inequitativo, ineficiente y va contra los principios constitucionales que definen la salud como derecho humano, en detrimento del bien común.

    El SGSSS, a los 18 años de su implantación, aún no cuenta con un sistema de información y las bases de datos existentes en las EPS, y también en el FOSYGA, distan de ser confiables. Se reconoce que un sistema de salud es en esencia un sistema de información. Los hospitales y clínicas de Colombia, especialmente las instituciones de carácter público, tienen una cartera que, se estima, es cinco o seis veces mayor que la cartera reclamada por las EPS, buena parte de la cual ya es de difícil cobro. Sin embargo, la prioridad ha sido resolver el problema económico de las EPS, no el de los hospitales.

    Son muchas las voces que claman por un riguroso control de la manera como las EPS invierten los recursos de la salud, de carácter público por ser recursos parafiscales. Las EPS muestran un grande y rápido crecimiento patrimonial y han

    The Parametric Source Term (PST) software allows estimation of radioactivity release fractions for Level 2 Probabilistic Safety Assessments (PSAs). PST was developed at the Idaho National Engineering Laboratory (INEL) for the Nuclear Regulatory Commission's (NRC's) Accident Sequence Precursor (ASP) Program. PST contains a framework of equations that model activity transport between volumes in the release pathway from the core, through the vessel, through the containment, and to the environment. PST quickly obtains exact solutions to differential equations for activity transport in each volume for each time interval. PST provides a superior method for source term estimation because it: ensures conservation of activity transported across various volumes in the release pathway; provides limited consideration of the time-dependent behavior of input parameter uncertainty distributions; allows input to be quantified using state-of-the-art severe accident analysis code results; increases modeling flexibility because linkage between volumes is specified by user input; and allows other types of Light Water Reactor (LWR) plant designs to be evaluated with minimal modifications. PST is a microcomputer-based system that allows the analyst more flexibility than a mainframe system. PST has been developed to run with both MS DOS and MS Windows 95/NT operating systems. PST has the capability to load ASP Source Term Vector (STV) information, import pre-specified default input for the 6 Pressurized Water Reactors (PWRs) initially analyzed in the NRC ASP program, allow input value modifications for release fraction sensitivity studies, export user-specified default input for the LWR being modeled, report results of radioactivity release calculations at each time interval, and generate formatted results that can interface with other risk assessment codes. This report describes the PST model and provides guidelines for using PST

    Full Text Available SUMMARY The works to be presented in this paper are related with information technology application on the intelligent building concept. A distributed system targeted for integrated building monitoring and control will be presented. The system is also able to support business activities and services. The concept of domot introduced (domot = “domus" + "robot" as the third active occupant of the building, coexisting with users and managers, and able to manage resources and be at other occupant disposal. The system relies on the definition of two types of template architectures, to be used as references by the software and hardware parts of the system. The software reference template is based on a heterogeneous distributed network of workstations, running a set of process with interprocess communication based on the client-server paradigm. The hardware reference template is based on a architecture based on two levels of networks; the first one is used for the communication between high-level control workstations (targeted for supervision and monitoring and the second one is targeted to support low-level controllers communcation. These two types of templates constitute the basis for a robust and open system based implementation of an infrastructure that is able to support both business activities and the single occupant wishes, enabling synergistic developments. The user interface, which may run anywhere in the world as far as a TCP-IP connection is available, is hierarchically organised; specific information and dialogues are provided for the monitoring and management of different types of devices and systems installed in the building. The systems already integrated are intrusion, CCTV and PABX. Access control and HVAC will follow in the near future.

    Long-term heavy cannabis use can result in memory impairment. Adolescent users may be especially vulnerable to the adverse neurocognitive effects of cannabis. In a cross-sectional and prospective neuropsychological study of 181 adolescents aged 16-20 (mean 18.3 years), we compared performance indices from one of the most widely used measures of learning and memory--the Rey Auditory Verbal Learning Test--between cannabis users (n=52; mean 2.4 years of use, 14 days/month, median abstinence 20.3 h), alcohol users (n=67) and non-user controls (n=62) matched for age, education and premorbid intellectual ability (assessed prospectively), and alcohol consumption for cannabis and alcohol users. Cannabis users performed significantly worse than alcohol users and non-users on all performance indices. They recalled significantly fewer words overall (pmemory performance after controlling for extent of exposure to cannabis. Despite relatively brief exposure, adolescent cannabis users relative to their age-matched counterparts demonstrated similar memory deficits to those reported in adult long-term heavy users. The results indicate that cannabis adversely affects the developing brain and reinforce concerns regarding the impact of early exposure.

Also, the combination of heuristic and model-based techniques allows to synthesize robust controllers for real application situations and, furthermore, effciently manage the insulin usage. Nevertheless, the actual application of a closed-loop system on a human being should require higher dimension models to fit different situations, a proven robust controller and wide adaptability to different patients and their meal intake routine.

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

    2010-01-01

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

    Arias, E. F.

    La Unión Astronómica Internacional (IAU) recomendó la adopción de un nuevo sistema de referencia celeste baricéntrico cuyo plano fundamental y origen de ascensiones rectas estén próximos, respectivamente, al ecuador y equinoccio dinámicos J2000.0. El nuevo sistema de referencia estará materializado por las posiciones J2000.0 de radiofuentes extragalácticas determinadas con la técnica de interferometría de larga línea de base (VLBI). El Working Group on Reference Frames de la IAU (WGRF) decidió adoptar (Grasse, 1995) al sistema de referencia celeste extragaláctico del Servicio Internacional de la Rotación Terrestre (IERS) como futuro sistema de referencia celeste convencional bajo el nombre International Celestial Reference System (ICRS) y encomendó su mantenimiento futuro al IERS. El marco de referencia que materializará al ICRS contiene posiciones precisas J2000.0 de más de 600 radiofuentes extragalácticas. Las coordenadas fueron ajustadas en una única solución VLBI en la cual se incluyeron todas las observaciones realizadas hasta octubre de 1995 con la técnica de adquisición de datos VLBI Mark III. Para minimizar los errores sistemáticos que pueden afectar la calidad del marco de referencia se introdujeron mejoras sustanciales en la modelización y en la selección de datos. Un subconjunto de objetos del marco de referencia se utilizó para referir las posiciones estelares determinadas con el satélite astrométrico Hipparcos al ICRS.

    In this paper the design, development and validation of an intelligent tutorial system oriented to the instruction of techniques of tuning of control systems is described. This system is based on systems previously developed in the Simulation Unit of the Instituto de Investigaciones Electricas (IIE). The designed system accounts with four modules: of knowledge, the student model, of tutor and of interface, basic characteristics that allows to locate this system in the context of the intelligent tutorial systems. In this system in particular, the knowledge module was only modified, because advantage is taken of the existing structure to incorporate a new dominion of application: the one of the techniques of tuning of control systems. The system maintains the characteristic that it can also be used as a consultation system. In addition to the design and validation of the tutorial system, when following the methodology of processing the degree of generality of the developed system, was evaluated, taking into account the evaluation and quantification of metrics that the engineering software proposes.

    The TAILSIM program uses a 4th order Runge-Kutta method to integrate the standard aircraft equations-of-motion (EOM). The EOM determine three translational and three rotational accelerations about the aircraft's body axis reference system. The forces and moments that drive the EOM are determined from aerodynamic coefficients, dynamic derivatives, and control inputs. Values for these terms are determined from linear interpolation of tables that are a function of parameters such as angle-of-attack and surface deflections. Buildup equations combine these terms and dimensionalize them to generate the driving total forces and moments. Features that make TAILSIM applicable to studies of tailplane stall include modeling of the reversible control System, modeling of the pilot performing a load factor and/or airspeed command task, and modeling of vertical gusts. The reversible control system dynamics can be described as two hinged masses connected by a spring. resulting in a fifth order system. The pilot model is a standard form of lead-lag with a time delay applied to an integrated pitch rate and/or airspeed error feedback. The time delay is implemented by a Pade approximation, while the commanded pitch rate is determined by a commanded load factor. Vertical gust inputs include a single 1-cosine gust and a continuous NASA Dryden gust model. These dynamic models. coupled with the use of a nonlinear database, allow the tailplane stall characteristics, elevator response, and resulting aircraft response, to be modeled. A useful output capability of the TAILSIM program is the ability to display multiple post-run plot pages to allow a quick assessment of the time history response. There are 16 plot pages currently available to the user. Each plot page displays 9 parameters. Each parameter can also be displayed individually. on a one plot-per-page format. For a more refined display of the results the program can also create files of tabulated data. which can then be used by other

    Slycat™ is a web-based system for performing data analysis and visualization of potentially large quantities of remote, high-dimensional data. Slycat™ specializes in working with ensemble data. An ensemble is a group of related data sets, which typically consists of a set of simulation runs exploring the same problem space. An ensemble can be thought of as a set of samples within a multi-variate domain, where each sample is a vector whose value defines a point in high-dimensional space. To understand and describe the underlying problem being modeled in the simulations, ensemble analysis looks for shared behaviors and common features across the group of runs. Additionally, ensemble analysis tries to quantify differences found in any members that deviate from the rest of the group. The Slycat™ system integrates data management, scalable analysis, and visualization. Results are viewed remotely on a user’s desktop via commodity web clients using a multi-tiered hierarchy of computation and data storage, as shown in Figure 1. Our goal is to operate on data as close to the source as possible, thereby reducing time and storage costs associated with data movement. Consequently, we are working to develop parallel analysis capabilities that operate on High Performance Computing (HPC) platforms, to explore approaches for reducing data size, and to implement strategies for staging computation across the Slycat™ hierarchy. Within Slycat™, data and visual analysis are organized around projects, which are shared by a project team. Project members are explicitly added, each with a designated set of permissions. Although users sign-in to access Slycat™, individual accounts are not maintained. Instead, authentication is used to determine project access. Within projects, Slycat™ models capture analysis results and enable data exploration through various visual representations. Although for scientists each simulation run is a model of real-world phenomena given certain

    The TMAP Code was written at the Idaho National Engineering and Environmental Laboratory by Brad Merrill and James Jones in the late 1980s as a tool for safety analysis of systems involving tritium. Since then it was upgraded to TMAP4 and has been used in numerous applications including experiments supporting fusion safety, predictions for advanced systems such as the International Thermonuclear Experimental Reactor (ITER), and estimates involving tritium production technologies. Its further upgrade to TMAP2000 and now to TMAP7 was accomplished in response to several needs. TMAP and TMAP4 had the capacity to deal with only a single trap for diffusing gaseous species in solid structures. TMAP7 includes up to three separate traps and up to 10 diffusing species. The original code had difficulty dealing with heteronuclear molecule formation such as HD and DT under solution-law dependent diffusion boundary conditions. That difficulty has been overcome. TMAP7 automatically generates heteronuclear molecular partial pressures when solubilities and partial pressures of the homonuclear molecular species are provided for law-dependent diffusion boundary conditions. A further sophistication is the addition of non-diffusing surface species. Atoms such as oxygen or nitrogen or formation and decay or combination of hydroxyl radicals on metal surfaces are sometimes important in reactions with diffusing hydrogen isotopes but do not themselves diffuse appreciably in the material. TMAP7 will accommodate up to 30 such surface species, allowing the user to specify relationships between those surface concentrations and partial pressures of gaseous species above the surfaces or to form them dynamically by combining diffusion species or other surface species. Additionally, TMAP7 allows the user to include a surface binding energy and an adsorption barrier energy. The code includes asymmetrical diffusion between the surface sites and regular diffusion sites in the bulk. All of the

    The event tree analysis technique has been used in Probabilistic Safety Assessment for LWRs to delineate various accident scenarios leading to core melt or containment failure and to evaluate their frequencies. This technique often requires manual preparation of event trees with iterative process and time-consuming work in data handling. For the purpose of reducing manual efforts in event tree analysis, we developed a new software package named ETAP (Event Tree Analysis Supporting Program) for event tree analysis. ETAP is an interactive PC-based program which has the ability to construct, update, document, and quantify event trees. Because of its fast running capability to quantify event trees, use of the EATP program can make it easy to perform the sensitivity studies on a variety of system/containment performance issues. This report provides a user's manual for ETAP, which describes the structure, installation, and use of EATP. This software runs on NEC/PC-9800 or compatible PCs that have a 640 KB memory and MS-DOS 2.11 or higher. (author)

    AMBER is a Particle-In-Cell (PIC) code which models the evolution of a representative slice of a relativistic electron beam in a linear accelerator. The beam is modeled as a steady flow and therefore no electromagnetic waves: all the fields (external and self-fields) are electrostatic and magnetostatic fields (for a complete description, see chapter 5). The possible elements describing the accelerator lattice are solenoids, accelerating gaps, pipes and apertures. Several kinds of beam distribution can be loaded: KV, gaussian, semi-gaussian, etc. Alternatively, the user can reconstruct (or load) a distribution from the output of another codefile, for example, an interface generating the beam distribution from output produced from EGUN or LSP codes is available as an option. This documentation first describes in detail the input files needed to run AMBER and the procedure to start the executable. The possible data files and graphical output are explained in the two following chapters. The last chapter describes the physics model and numerical techniques used. An example of input files and the result obtained with these inputs are also given in the Appendix

    The Lower Hybrid Simulation Code (LSC) is a computational model of lower hybrid current drive in the presence of an electric field. Details of geometry, plasma profiles, and circuit equations are treated. Two-dimensional velocity space effects are approximated in a one-dimensional Fokker-Planck treatment. The LSC was originally written to be a module for lower hybrid current drive called by the Tokamak Simulation Code (TSC), which is a numerical model of an axisymmetric tokamak plasma and the associated control systems. The TSC simulates the time evolution of a free boundary plasma by solving the MHD equations on a rectangular computational grid. The MHD equations are coupled to the external circuits (representing poloidal field coils) through the boundary conditions. The code includes provisions for modeling the control system, external heating, and fusion heating. The LSC module can also be called by the TRANSP code. TRANSP represents the plasma with an axisymmetric, fixed-boundary model and focuses on calculation of plasma transport to determine transport coefficients from data on power inputs and parameters reached. This manual covers the basic material needed to use the LSC. If run in conjunction with TSC, the ''TSC Users Manual'' should be consulted. If run in conjunction with TRANSP, on-line documentation will be helpful. A theoretical background of the governing equations and numerical methods is given. Information on obtaining, compiling, and running the code is also provided

The overall objective of the first phase of the National Biodigester Programme is 'The dissemination of domestic biodigesters as an indigenous, sustainable energy source through the development of a commercial, market oriented, biodigester sector in selected provinces of Cambodia'. The program aims to support the construction of 17,500 biodigesters in at least 6 provinces over the period of 2006 to 2009. To gain insights and feedbacks on the impacts of their activities to date, NBP commissioned the Cambodia Institute of Development Study (CIDS) to carry out a Biodigester User Survey in January 2007. The purpose of the survey is to evaluate the effects of domestic biodigester installations, as supported by the program, on 100 households in 3 provinces in Cambodia- Kampong Cham, Kandal and Svay Rieng.

    The COSYMA system for reactor accident consequence assessment (ACA) is intended to provide a flexible package which will allow users in a variety of institutions and in different European countries to investigate special problems by appropriate choice of parameter values and data sets. It has been developed to serve as a research tool for investigating and understanding the broad spectrum of accident consequences rather than to perform 'quick and easy' risk calculations. The easy access to intermediate and final results and the availability of flexible evaluation programs means that detailed parameter studies can be carried out, identifying the most important sensitivities and quantifying the essential uncertainties. COSYMA is intended also for use by people who are not specialists in the various disciplines of ACA modelling, but wish to use such a program. However, some familiarity with this area is required to enable them to make informed choices of models and parameter values for the particular application considered. Some assistance is given by providing default values for all relevant parameters, and the documents distributed together with the code will give some guidance on the appropriate choice of parameter values or simplifications of the code system for special applications.

    Durante o survey de associações OB do disco Galáctico, foi constatada a multiplicidade do sistema HD 208905, pertencentes à associação de Cep OB2. Este objeto está classificado como uma estrela pertencente a um sistema múltiplo, com magnitude mv = 7.0 e tipo espectral B1V. De fato, os espectros de HD 208905 apresentam perfis de absorção triplicados. Dois dos perfis são bastante similares entre si, e são estreitos e bem definidos, sugerindo que as velocidades rotacionais projetadas (v sin i) das duas estrelas são baixas. Os espectros obtidos também apresentam perfis mais alargados que poderiam ser atribuídos a uma terceira componente estelar com v sin i mais alto. A análise de HD 208905 é baseada no estudo da variação da posição relativa dos perfis espectrais de acordo com a fase do sistema. Nossos dados observacionais são um conjunto de espectros de alta resolução obtidos no McDonald Observatory (Universidade do Texas, Austin), Kitt Peak National Observatory e Palomar Observatory, cobrindo o período de 10/91 até 12/95. Inicialmente, calculamos a velocidade radial de cada componente do sistema, considerando o desvio Doppler sofrido por cada estrela. As velocidades radiais medidas foram, em seguida, corrigidas para velocidades radiais heliocêntricas. O passo seguinte constituiu na determinação da periodicidade da série temporal definida pelas medidas das velocidades radiais heliocêntricas através da análise de Fourier. A nossa base de dados não permitiu definir uma solução única para o sistema HD 208905. As possíveis soluções encontradas têm períodos entre 1 e 27 dias e serão apresentadas e discutidas.

    Full Text Available Los sistemas agroforestales (SAF son una forma de uso de la tierra en donde las leñosas interactúan con los cultivos y/o animales, con la finalidad de diversificar y optimizar la producción de manera sostenida. Sin embargo, estos sistemas tienen limitantes originados por una combinación inadecuada de las diferentes especies, lo que resulta en competencia entre ellas. Las características radiculares de las especies leñosas tienen un papel importante en el éxito de los SAF, ya que indican modificaciones que pudieran existir entre especies asociadas. Por tanto, el objetivo de esta revisión es analizar la importancia de las interacciones radiculares, los criterios para el manejo con base en las características morfológicas y patrones de crecimiento entre especies y su impacto en los SAF. La incorporación de especies arbóreas dentro de los cultivos requiere de objetivos claros; es decir, conocer el papel que desempeñarían dentro del sistema. No es redituable utilizar especies arbóreas que no poseen cierto valor o producto, ya que la competencia entre los árboles y los cultivos es solamente admisible si es compensada a través de porlas ventajas con relación a los aumentos en la productividad de sistema. Son deseables aquellas especies arbóreas cuyas raíces sean agresivas con relación a los sistemas radiculares del cultivo asociado, y que manifiesten un crecimiento lateral profundo y/o posean una alta plasticidad. Una opción para reducir la competencia radicular es la regulación del espaciamiento y/o distribución de las diversas especies asociadas, así como la aplicación de prácticas de manejo. Los patrones de la actividad radicular de las plantas difieren entre especies, su conocimiento puede ayudar a evitar competencia excesiva y pérdidas de nutrientes en SAF con la asignación óptima del espacio y recursos disponibles.

  1. La evolución de sistemas complejos: el caso del sistema inmune en animales

    Directory of Open Access Journals (Sweden)

    2009-10-01

    Full Text Available Resumen   El sistema inmune en animales comprende una serie de mecanismos celulares y moleculares que de manera conjunta mantienen la integridad fisiológica y genética de los organismos. Convencionalmente se ha considerado la existencia de dos clases de inmunidad, la innata y la adaptativa. La primera es ancestral, con variabilidad limitada y baja discriminación, mientras que la segunda es altamente variable, específica y restringida a vertebrados mandibulados. La inmunidad adaptativa se basa en receptores de antígeno que se rearreglan somáticamente para generar una diversidad casi ilimitada de moléculas. Este mecanismo de recombinación somática muy probablemente emergió como consecuencia de un evento de transferencia horizontal de transposones y transposas bacterianas en el ancestro de los vertebrados mandibulados. El reciente descubrimiento en vertebrados no mandibulados e invertebrados de mecanismos de inmunidad adaptativa alternos, plantea la necesidad de considerar nuevos elementos en la construcción de un modelo evolutivo de la inmunidad en animales. Algunos de esos elementos se esbozan en este ensayo.   Abstract   The immune system in animals is composed by a series of cell and molecular mechanisms that coordinately maintain the physiological and genetic integrity of the organism. Traditionally, two classes of immunity have been considered, the innate immunity and the adaptive immunity. The former is ancestral, with limited variability and low discrimination. The latter is highly variable, specific and limited to jawed vertebrates. Adaptive immunity is based on antigen receptors that rearrange somatically to generate a nearly unlimited diversity of molecules. Likely, this mechanism of somatic recombination arose as a consequence of a horizontal transfer of transposons and transposases from bacterial genomes in the ancestor of jawed vertebrates. The recent discovery in jawless vertebrates and invertebrates of alternative

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

    Identifying online user reputation based on the rating information of the user-object bipartite networks is important for understanding online user collective behaviors. Based on the Bayesian analysis, we present a parameter-free algorithm for ranking online user reputation, where the user reputation is calculated based on the probability that their ratings are consistent with the main part of all user opinions. The experimental results show that the AUC values of the presented algorithm could reach 0.8929 and 0.8483 for the MovieLens and Netflix data sets, respectively, which is better than the results generated by the CR and IARR methods. Furthermore, the experimental results for different user groups indicate that the presented algorithm outperforms the iterative ranking methods in both ranking accuracy and computation complexity. Moreover, the results for the synthetic networks show that the computation complexity of the presented algorithm is a linear function of the network size, which suggests that the presented algorithm is very effective and efficient for the large scale dynamic online systems.

    In this work a measuring system of partial discharges based on the traditional electrical detection technique is presented, but that unlike the existing systems it uses an optical link of communication. On one hand, the optical fiber avoids that the electromagnetic interference of the area affects the measurement and on the other hand, allows to make measurements online. With a personal computer and an application program the system is controlled, besides storing and displaying graphically the acquired data. As a result of this thesis the developed system obtains the magnitude and the phase of every partial discharge occurred during a time interval fixed or selected by the user, as well as the total number of discharges. In a graphical form it presents the magnitude and the phase of each discharge, in addition to the corresponding histogram of frequencies. [Spanish] En este trabajo se presenta un sistema de medicion de descargas parciales basado en la tecnica de deteccion electrica tradicional, pero que a diferencia de los sistemas existentes utiliza un enlace de comunicacion optico. Por un lado, la fibra optica evita que la interferencia electromagnetica del medio afecte la medicion y por otro, permite hacer mediciones en linea. Con una computadora personal y un programa de aplicacion se controla el sistema, ademas de almacenar y presentar graficamente la informacion adquirida. Como resultado de esta tesis el sistema desarrollado obtiene la magnitud y la fase de cada descarga parcial ocurrida durante un intervalo de tiempo fijo o seleccionado por el usuario, asi como el numero total de descargas. En forma grafica presenta la magnitud y la fase de cada descarga, ademas del histograma de frecuencias correspondiente.

    2008-10-01

    The excitation of pulsation modes in Beta Cephei and Slowly Pulsating B stars is known to be very sensitive to opacity changes in the stellar interior where T ~ 2 x 10E5 K. In this region differences in opacity up to ~ 50% can be induced by the choice between OPAL and OP opacity tables, and between two different metal mixtures (Grevesse & Noels 1993 and Asplund et al. 2005). We have extended the non-adiabatic computations presented in Miglio et al. (2007) towards models of higher mass and pulsation modes of degree l = 3, and we present here the instability domains in the HR- and log P-log Teff diagrams resulting from different choices of opacity tables, and for three different metallicities. FAMIAS (Frequency Analysis and Mode Identification for AsteroSeismology) is a collection of state-of-the-art software tools for the analysis of photometric and spectroscopic time series data. It is one of the deliverables of the Work Package NA5: Asteroseismology of the European Coordination Action in Helio-and Asteroseismology (HELAS). Two main sets of tools are incorporated in FAMIAS. The first set allows to search for periodicities in the data using Fourier and non-linear least-squares fitting algorithms. The other set allows to carry out a mode identification for the detected pulsation frequencies to determine their pulsational quantum numbers, the harmonic degree, m. The types of stars to which famias is applicable are main-sequence pulsators hotter than the Sun. This includes the Gamma Dor stars, Delta Sct stars, the slowly pulsating B stars and the Beta Cep stars - basically all pulsating main-sequence stars, for which empirical mode identification is required to successfully carry out asteroseismology. This user manual describes how to use the different features of FAMIAS and provides two tutorials that demonstrate the usage of FAMIAS for spectroscopic and photometric mode identification.

  17. Audit result and its users

    2014-01-01

    Full Text Available The article identifies essence of the “audit result” and “users of audit result” notions and characteristics of the key audit results user. It shows that in order to give a wide characteristic of users it is expedient to unite all objects, which could be used (audit report, fact of refusal to conduct audit and information that is submitted to managers in the process of audit with the term “audit result” and classify it depending on the terms of submission by final and intermediate result. The article offers to define audit results user as a person, persons or category of persons for whom the auditor prepares the audit report and, in cases, envisaged by international standards of the audit and domestic legislative and regulatory acts, provides other additional information concerning audit issues. In order to identify the key audit results user the article distributes all audit tasks into two groups depending on possibilities of identification of users. The article proves that the key user should be identified especially in cases of a mandatory audit and this process should go in interconnection with the mechanism of allocation of a key user of financial reports. It offers to consider external users with direct financial interests, who cannot request economic subjects directly to provide information and who should rely on general financial reports and audit report when receiving significant portion of information they need, as the key user. The article makes proposals on specification of the categorical mechanism in the sphere of audit, which are the basis for audit quality assessment, identification of possibilities and conditions of appearance of the necessary and sufficient trust to the auditor opinion.

  18. Peak experiences of psilocybin users and non-users.

    2013-01-01

    Maslow (1970) defined peak experiences as the most wonderful experiences of a person's life, which may include a sense of awe, well-being, or transcendence. Furthermore, recent research has suggested that psilocybin can produce experiences subjectively rated as uniquely meaningful and significant (Griffiths et al. 2006). It is therefore possible that psilocybin may facilitate or change the nature of peak experiences in users compared to non-users. This study was designed to compare the peak experiences of psilocybin users and non-users, to evaluate the frequency of peak experiences while under the influence of psilocybin, and to assess the perceived degree of alteration of consciousness during these experiences. Participants were recruited through convenience and snowball sampling from undergraduate classes and at a musical event. Participants were divided into three groups, those who reported a peak experience while under the influence of psilocybin (psilocybin peak experience: PPE), participants who had used psilocybin but reported their peak experiences did not occur while they were under the influence of psilocybin (non-psilocybin peak experience: NPPE), and participants who had never used psilocybin (non-user: NU). A total of 101 participants were asked to think about their peak experiences and complete a measure evaluating the degree of alteration of consciousness during that experience. Results indicated that 47% of psilocybin users reported their peak experience occurred while using psilocybin. In addition, there were significant differences among the three groups on all dimensions of alteration of consciousness. Future research is necessary to identify factors that influence the peak experiences of psilocybin users in naturalistic settings and contribute to the different characteristics of peak experiences of psilocybin users and non-users.

  10. Profiting from innovative user communities

    DEFF Research Database (Denmark)

    Jeppesen, Lars Bo

    Modding - the modification of existing products by consumers - is increasingly exploited by manufacturers to enhance product development and sales. In the computer games industry modding has evolved into a development model in which users act as unpaid `complementors' to manufacturers' product pl......, a manufacturer can incorporate and commercialize the best complements found in the user communities. Keywords: innovation, modding, user communities, software platform, business model. JEL code(s): L21; L23; O31; O32...... platforms. This article explains how manufacturers can profit from their abilities to organize and facilitate a process of innovation by user communities and capture the value of the innovations produced in such communities. When managed strategically, two distinct, but not mutually exclusive business...... models appear from the production of user complements: firstly, a manufacturer can let the (free) user complements `drift' in the user communities, where they increase the value to consumers of owning the given platform and thus can be expected to generate increased platform sales, and secondly...

  11. CUP: contraceptive users pamphlet.

    Science.gov (United States)

    1986-02-01

    This pamphlet, edited by an ad hoc committee of several consultants, scientists, theologians, public health and family planning directors, and an international attorney, covers the following topics: contra-conception; choices of contraceptives; contraceptive package information; copper IUDs; pelvic inflammatory disease (PID); sexually transmitted diseases; and acquired immunodeficiency syndrome. It includes a questionnaire for sexually transmitted diseases (STDs). Professor Joseph Goldzieher describes the "Contra-Conception" database as "a synthesis of up-to-date literature and contemporary guidelines, designed to provide ready access for practicing physicians and medical students." It contains data on several types of hormonal contraception. "Contra-Conceptions" is designed to allow the physician to set his or her own pace when working with the computer, and no previous computer experience is required. 1 of the program's many innovative features is the patient-profiling/decisionmaking section which can be used in the doctor's office to help decide what type of hormonal contraceptive is appropriate for a particular patient. The program permits the doctor to evaluate the significance of patient variables such as parity, smoking, menstrual difficulties and helps the doctor to identify the risks and benefits of the various methods and, ultimately, to make a balanced decision in the context of the most recent data. Contraceptive drugs and devices should include detailed information on the following: description of formula or device; indication, usage, and contraindications, clinical pharmacology and toxicology; dose-related risk; pregnancies per 100 women year; and detailed warning. The sequence of major pathophysiological reactions associated with copper IUDs is identified as are special problems of pelvic infections in users of copper IUDs. Those women who use oral contraceptives (OCs) or a barrier method of contraception or whose partners use a condom have a lower

    COSIS (COre State Indication System) which implemented in the SMART research reactor plays a role to supply the core state parameters or graphs for the operator to recognize the core state effectively. The followings are the main functions of COSIS. Validity Check for the Process Signals and Determination of the COSIS Inputs (SIGVAL), Coolant Flow Rate Calculation (FLOW), Core Thermal Power Calculation (COREPOW), In-core 3-Dimensional Power Distribution Calculation and Peaking Parameters Generation (POWER3D), Azimuthal Tilt Calculation (AZITILT). This report describes the structures of the I/O files that are essential for the users to run COSIS. COSIS handles the following 4 input files. DATABASE: The base input file, COSIS.INP: The signal input file, CCS.DAT: File required for the in-core detector signal processing and the 3-D power distribution calculation, TPFH2O: Steam table for the water properties The DATABASE file contains the base information for a nuclear power plant and is read at the first COSIS calculation. The COSIS.INP file contains the process input and detector signals, and is read by COSIS at every second. CCS.DAT file, that is produced by the COSISMAS code, contains the information for the in-core detector signal processing and the 3-D power distribution calculation. TPFH2O file is a steam table and is written in binary format. COSIS produces the following 4 output files. DATABASE.OUT: The output file for the DATABASE input file, COSIS.OUT: The normal output file produced after the COSIS calculation, COSIS.SUM: File for the operator to recognize the core state effectively, MAS S IG: File to run the COSISMAS code The DATABASE.OUT file is produced right after finishing DATABASE processing. The COSIS.OUT file is produced after finishing the input signal processing and the main COSIS calculation. The COSIS.SUM file is the summary file of the COSIS results for the operator to recognize the core state effectively. The MAS S IG file is the COSISMAS input

Methods: Descriptive study with qualitative approach, carried out in a Basic Health Unit, Fortaleza, Brazil, where practical activities of the Education Program of Work for Health of the University of Fortaleza were performed. Fifty eight service users were involved, following inclusion criteria: being present during the data collection, age over 18, regardless of sex, and voluntary participation. Data collection occurred in December 2009, through semi-structured interview. The data associated with the identification of users were processed in Microsoft Office Excel 2007, being organizedstatistically in table. Data related to qualitative aspects were analyzed according to the technique of content analysis. Results: 56 (97% were women, with ages ranging between 21 and 40 years, 34 (59% were married and 53 (91% are literate. On family income, 55 (95%received less than two minimum salaries per month. In order to facilitate understanding the speech of users, these were evaluated from the perspective of two categories: knowledge about embracement and satisfaction with embracement. Conclusion: Users have a limited view of the significance and magnitude of the embracement to provide the care. Although satisfied with the service, respondents report as negative aspects: the shortage of professionals, the professional relationship with user impaired due to constant delays of the professional, and the dehumanization of care.

    Full Text Available CAPTCHA is one of the most common solutions to check if the user trying to enter a Website is a real person or an automated piece of software. This challenge-response test, implemented in many Internet Websites, emphasizes the gaps between accessibility and security on the Internet, as it poses an obstacle for the learning-impaired in the reading and comprehension of what is presented in the test. Various types of CAPTCHA tests have been developed in order to address accessibility and security issues. The objective of this study is to investigate how the differences between various CAPTCHA tests affect user experience among populations with and without learning disabilities. A questionnaire accompanied by experiencing five different tests was administered to 212 users, 60 of them with learning disabilities. Response rates for each test and levels of success were collected automatically. Findings suggest that users with learning disabilities have more difficulties in solving the tests, especially those with distorted texts, have more negative attitudes towards the CAPTCHA tests, but the response time has no statistical difference from users without learning disabilities. These insights can help to develop and implement solutions suitable for many users and especially for population with learning disabilities.

    This study takes into account some considerations about the classical logic when building knowledge. It states the logic of complexity, the complex thought and the rational, open and complex systems, as a new paradigm. In the light of the organization concept proposed by Morin, complex adaptative systems are emphasized, as well as other terms such as order, disorder, incidental events and noises. The self-eco-organizer process, takes the human being thinking as starting point and as dynamizer of simple and complex processes in the construction of knowledge about reality. Some research studies such as those of Erdmann, Meirelles and Pradebon show some ways in which one can learn from the organizational reality of nursing, the exercise of complex thinking in uncertainty, in tenous limits, in heterogeneity, diversity and pluralism of phenomena in its aspect, interactions and associations. The inter subjectivity states a new concept of space and of temporality. The care system organization in nursing visualizes several dimensions of "caríng": to care for himself, to care for himself together with the other, to be looked after by the other, to feel and the process of personal care system, the body itself as the nucleus of care, the fact of belonging to the system of multiple caring relations and the care for nature getting integrated to other beings and other social, natural systems, and in thisway strengthen the feeling of ownership, in search of a better survival, vitality, life human quality.

    Full Text Available RESUMEN Los peces poseen un sistema inmune con muchas de las células y sustancias humorales presentes en vertebrados superiores, pero cuentan también con componentes y funciones especiales, como los centros melanomacrófagos y la capacidad fagocítica de los enterocitos por citar solo algunas de ellas, que difieren profundamente con sus similares en otras especies y que aún hoy son pobremente comprendidas. Sumado a esto, el ambiente acuático y más, el ambiente acuático productivo, es de por si complejo de manera que las posibilidades de las interacciones biológicas son enormes y los procesos difícilmente predecibles. La vacunación es tal vez una de las herramientas más importantes para el control de enfermedades bacterianas en peces, no solo por su potencial preventivo y correctivo sino también por sus bondades con el ambiente y con la salud pública que contrastan notoriamente con los tratamientos antibióticos. El éxito de las vacunas en especies piscícolas depende en buena medida del conocimiento adecuado del sistema inmunológico de los peces, de las interacciones hospedero-ambiente-patógeno, así como de las particularidades de los sistemas productivos. Con todo, la vacunación en ambientes acuáticos se enfrenta a un sinnúmero de dificultades que deben ser abordadas antes que con un enfoque unilateral farmacológico, con una aproximación integral en la que se incluye el uso de herramientas epidemiológicas, clínicas, patológicas, microbiológicas, etc. Palabras clave: vacunación, peces, inmunidad de peces, enfermedades infecciosas en peces.
