Proposal of an On-demand Software Deployment System Based on Application Streaming, Virtualization Techniques and P2P Transport

This paper presents the work in progress of an on-demand software deployment system based on application virtualization concepts which eliminates the need of software installation and configuration on each computer. Some mechanisms were created, such as mapping of utilization of resources by the application to improve the software distribution and startup; a virtualization middleware which give all resources needed for the software execution; an asynchronous P2P transport used to optimizing distribution on the network; and off-line support where the user can execute the application even when the server is not available or when is out of the network. © Springer-Verlag Berlin Heidelberg 2010.

Design of a reconfigurable pseudorandom number generator for use in intelligent systems

This paper deals with the design of a network-on-chip reconfigurable pseudorandom number generation unit that can map and execute meta-heuristic algorithms in hardware. The unit can be configured to implement one of the following five linear generator algorithms: a multiplicative congruential, a mixed congruential, a standard multiple recursive, a mixed multiple recursive, and a multiply-with-carry. The generation unit can be used both as a pseudorandom and a message passing-based server, which is able to produce pseudorandom numbers on demand, sending them to the network-on-chip blocks that originate the service request. The generator architecture has been mapped to a field programmable gate array, and showed that millions of numbers in 32-, 64-, 96-, or 128-bit formats can be produced in tens of milliseconds.

Reducing the gap between mobile and intelligent software agents

This paper presents an approach to integrate an artificial intelligence (AI) technique, concretely rule-based processing, into mobile agents. In particular, it focuses on the aspects of designing and implementing an appropriate inference engine of small size to reduce migration costs. The main goal is combine two lines of agent research, First, the engineering oriented approach on mobile agent architectures, and, second, the AI related approach on inference engines driven by rules expressed in a restricted subset of first-order predicate logic (FOPL). In addition to size reduction, the main functions of this type of engine were isolated, generalized and implemented as dynamic components, making possible not only their migration with the agent, but also their dynamic migration and loading on demand. A set of classes for representing and exchanging knowledge between rule-based systems was also proposed.

Fuzzy rule-based system for evaluation of uncertainty transaction in cassava chain

A fuzzy ruled-based system was developed in this study and resulted in an index indicating the level of uncertainty related to commercial transactions between cassava growers and their dealers. The fuzzy system was developed based on Transaction Cost Economics approach. The fuzzy system was developed from input variables regarding information sharing between grower and dealer on “Demand/purchase Forecasting”, “Production Forecasting” and “Production Innovation”. The output variable is the level of uncertainty regarding the transaction between seller and buyer agent, which may serve as a system for detecting inefficiencies. Evidences from 27 cassava growers registered in the Regional Development Offices of Tupa and Assis, São Paulo, Brazil, and 48 of their dealers supported the development of the system. The mathematical model indicated that 55% of the growers present a Very High level of uncertainty, 33% present Medium or High. The others present Low or Very Low level of uncertainty. From the model, simulations of external interferences can be implemented in order to improve the degree of uncertainty and, thus, lower transaction costs.

Modelo de aplicação interativa para middleware Ginga de Televisão Digital: ambiente virtual de aprendizagem para Educação a Distância

O desenvolvimento de um modelo de aplicação interativa para Televisão Digital sobre a plataforma do middleware Ginga, do SBTVD, ainda em processo, é o tema deste artigo. A referida aplicação se traduz em um Ambiente Virtual de Aprendizagem, para Educação a Distância, aplicativo destinado a acesso on demand, fora da grade de programação síncrona da emissora, em TV Digital dotada de set top box, ou conversor digital, embarcado com Ginga NCL. A metodologia utilizada na construção deste produto da pesquisa de Mestrado (que também abrange uma monografia na área de Comunicação) integra três metodologias: um modelo de Design Instrucional (ou Educacional) adequado aos recursos da TV Digital; técnicas de Usabilidade e Arquitetura da Informação para a construção de um protótipo interativo; e um modelo de Desenvolvimento de Software de ciclo de vida ágil baseado em Prototipagem Evolutiva, a fim de se gerar um modelo de aplicação interativa para criação de conteúdos instrucionais focados em EaD através da mídia TV Digital.

Recepção por demanda de ficção seriada televisiva

O presente trabalho investiga a adequação para a recepção por demanda da estrutura da ficção seriada televisiva, matriz concebida para a veiculação em fluxo dentro da lógica da grade de programação. Centrando no gancho e repetição narrativa, foram realizados estudos de cena em Mckee (2006) e aplicadas as funções das personagens de Propp (1986) no corpus: A Grande Família, Duas Caras e Filhos do Carnaval. Em seguida, simulou-se a sua recepção por demanda e fluxo.

A iteratividade: do melodrama à narrativa audiovisual sob demanda

The repetition should be understood as the property of mass cultural products, originated from the need to minimize the dispersion of the audience in their enjoyment. Based on this assumption, this paper measures the rate of iteration manifested in the scripts of the following serial fictions: Duas Caras, A Grande Família and House of Cards. Established itself as a method of scene analysis proposed by McKee (2008), questioned whether the lack of classical education of the public and rescued the forms assumed by repeating the melodrama, romance-serial and dramaturgy: asides, monologues, confidences and planar scenes. The proposal was applied in two scripts for each of the aforementioned productions. Considering the data collected, it appears that there was reduction in repeat products offered on demand thanks to the possibility of handling the flow and the attention given receptor.

Task demand effects on postural control in older adults

The literature shows conflicting results regarding older adults' (OA) postural control performance. Differing task demands amongst scientific studies may contribute to such ambiguous results. Therefore, the purpose of this study was to examine the performance of postural control in older adults and the relationship between visual information and body sway as a function of task demands. Old and young adults (YA) maintained an upright stance on different bases of support (normal, tandem and reduced), both with and without vision, and both with and without room movement. In the more demanding tasks, the older adults displayed greater body sway than the younger adults and older adults were more influenced by the manipulation of the visual information due to the room movement. However, in the normal support condition, the influence of the moving room was similar for the two groups. These results suggest that task demand is an important aspect to consider when examining postural control in older adults. (c) 2006 Elsevier B.V. All rights reserved.
