Almoxarifado virtual: uma proposta de sustentabilidade por contrata????o de gerenciamento de meios

A iniciativa opera a partir da presta????o de um servi??o continuado de gerenciamento de meios. Em s??ntese, o ??rg??o parou de adquirir materiais de escrit??rio e de combate a inc??ndio e passou a operar com um almoxarifado terceirizado que fornece insumos de expediente, processamento de dados e combate a inc??ndios de seu pr??prio almoxarifado, num sistema similar a um stop shop, al??m de controlar os estoques de pronto uso de cada unidade e fazer o seu ressuprimento. Cada unidade da autarquia possui uma cota aut??noma de pedidos, num baixo valor em periodicidade mensal. Com tal iniciativa, as unidades se mant??m supridas o ano todo, sem desperd??cios e sem estoques, fazendo os seus pedidos no almoxarifado virtual e customizando suas cestas de necessidades de produtos para a produ????o processual e o atendimento sazonal das emerg??ncias ambientais

Projeto visita virtual e videoconfer??ncia judicial

Este projeto nasceu de uma parceria entre o Departamento Penitenci??rio Nacional e a Defensoria P??blica da Uni??o (DPU). Apresenta duas importantes vertentes no ??mbito da execu????o penal. A primeira relaciona-se ao direito de manuten????o dos v??nculos afetivos dos presidi??rios, possibilitando o contato deles com seus familiares e amigos; e a segunda refere-se ?? realiza????o de audi??ncias judiciais por videoconfer??ncia. Desde a implanta????o do Projeto Visita Virtual e Videoconfer??ncia Judicial, em maio de 2010, 509 presos participaram da visita virtual e puderam conversar e visualizar seus familiares e amigos por meio desse recurso, conferindo, assim, um resultado extremamente satisfat??rio, visto que h?? pelo menos um ano n??o recebiam visitas. De mar??o de 2011 at?? julho deste ano, foram realizadas 160 videoconfer??ncias

Escrit??rio virtual

Este projeto refere-se ?? implementa????o de um modelo de gest??o que reduz os custos com as ??reas-meio, e volta o seu potencial para o provimento de solu????es das necessidades do cliente. ?? uma nova forma de conceber o tempo, o espa??o e os relacionamentos, mediante a cria????o de um escrit??rio virtual que visa aproximar os t??cnicos aos seus clientes. O funcion??rio carrega consigo o notebook e o aparelho celular podendo trabalhar em qualquer lugar e a qualquer hora, com o objetivo de atender as demandas dos clientes com prontid??o e agilidade no momento da solicita????o.

Los modelos CAMEL y Promethee como instrumentos de análisis de la banca virtual en España

Consideramos de interés realizar un análisis financiero de la banca virtual en España para ser capaces de posicionar aquellas entidades bancarias que vieron en el canal de Internet una vía de expansión hacia nuevos clientes o como consolidación de los existentes, ya que todos los bancos creados en España de carácter virtual son filiales de grandes grupos bancarios. Utilizamos como modelos de análisis la aplicación de los métodos multicriterio CAMEL y Promethee. Como conclusiones del trabajo se observa que, independientemente del método utilizado, la entidad que mejor se posiciona para el periodo de análisis estudiado (2004-2010) es Bancopopular-e. No obstante, son entidades que todavía alcanzan valores muy bajas de rentabilidad y liquidez y donde datos como la eficiencia o la calidad de activos son muy mejorables.

A Generic Library for GUI Reasoning and Testing

Graphical user interfaces (GUIs) make software easy to use by providing the user with visual controls. Therefore, correctness of GUI's code is essential to the correct execution of the overall software. Models can help in the evaluation of interactive applications by allowing designers to concentrate on its more important aspects. This paper presents a generic model for language-independent reverse engineering of graphical user interface based applications, and we explore the integration of model-based testing techniques in our approach, thus allowing us to perform fault detection. A prototype tool has been constructed, which is already capable of deriving and testing a user interface behavioral model of applications written in Java/Swing.

Virtual simulation of the postsurgical cosmetic outcome in patientswith pectus excavatum

Pectus excavatum is the most common congenital deformity of the anterior chest wall, in which several ribs and the sternum grow abnormally. Nowadays, the surgical correction is carried out in children and adults through Nuss technic. This technic has been shown to be safe with major drivers as cosmesis and the prevention of psychological problems and social stress. Nowadays, no application is known to predict the cosmetic outcome of the pectus excavatum surgical correction. Such tool could be used to help the surgeon and the patient in the moment of deciding the need for surgery correction. This work is a first step to predict postsurgical outcome in pectus excavatum surgery correction. Facing this goal, it was firstly determined a point cloud of the skin surface along the thoracic wall using Computed Tomography (before surgical correction) and the Polhemus FastSCAN (after the surgical correction). Then, a surface mesh was reconstructed from the two point clouds using a Radial Basis Function algorithm for further affine registration between the meshes. After registration, one studied the surgical correction influence area (SCIA) of the thoracic wall. This SCIA was used to train, test and validate artificial neural networks in order to predict the surgical outcome of pectus excavatum correction and to determine the degree of convergence of SCIA in different patients. Often, ANN did not converge to a satisfactory solution (each patient had its own deformity characteristics), thus invalidating the creation of a mathematical model capable of estimating, with satisfactory results, the postsurgical outcome

This paper addresses the development of an ONVIF library to develop clients of video cameras. We address the choice of a web services toolkit, and how to use the selected toolkit to develop a basic library. From that, we discuss the implementation of features that ...

A contribution to a virtual enterprise taxonomy

This paper presents a taxonomy able to contribute to building a framework within the domain of Virtual Enterprises (VE). A VE taxonomy currently does not exist, and this lack is felt in the ambiguous way that some concepts are addressed, leading to a fragment understanding that hinders the development of the science of VE integration and management. The structure of the taxonomy developed is based on the view of the system as a 5-tuple consisting of Input, Control, Output, Mechanism, and Process, which is the underlying system-view in the well-know IDEF0 diagramming technique. In particular, this taxonomy addresses the VE extended lifecycle that implies the use of a meta-organization called Market of Resources, as an original contribution to the VE theory and practice. The taxonomy presented is constructed in a way to be easily complemented with other VE partial taxonomies that may be found in literature.

A importância da personagem virtual no contexto da animação 3D em tempo real

O desenvolvimento de personagens digitais tridimensionais1 na área da animação, a constante procura por soluções tecnológicas convincentes, aliado a uma estética própria, tem contribuído para o sucesso e afirmação da animação tridimensional, na indústria do entretenimento. Contudo, toda a obra que procura ou explora a vertente digital/3D, torna-se ‘vitima’ das limitações do render2 aplicado a uma sequência de imagens, devido ao aumento dos custos financeiros e humanos, assim como da influência e dificuldade implicadas no cumprimento dos objectivos e prazos. O tempo real tem assumido, cada vez mais, um papel predominante na indústria da animação interactiva. Com a evolução da tecnologia surgiu a necessidade de procurar a metodologia apropriada que sirva de alavanca para o desenvolvimento de animações 3D em tempo real, através de softwares open-source ou de baixo orçamento, para a redução de custos, que possibilite simultaneamente descartar qualquer dependência do render na animação 3D. O desenvolvimento de personagens em tempo real, possibilita o surgimento de uma nova abordagem: a interactividade na arte de animar. Esta possibilita a introdução de um vasto leque de novas aplicações e consequentemente, contribui para o aumento do interesse e curiosidade por parte do espectador. No entanto, a inserção, implementação e (ab)uso da tecnologia na área da animação, levanta questões atuais sobre qual o papel do animador. Esta dissertação procura analisar estes aspectos, dando apoio ao projecto de animação 3D em tempo real, denominado ‘PALCO’.

A taxonomy for virtual enterprises

The purpose of this paper is to present a taxonomy able to contribute to building a framework within the domain of Virtual Enterprises (VE), to facilitate the sharing of knowledge and contributions to knowledge, as well as for trust building among VE stakeholders. A VE taxonomy currently does not exist, and this lack is felt in the ambiguous way that some concepts are addressed, leading to a fragment understanding that hinders the development of the science of VE integration and management. The structure of the taxonomy developed is based on the view of the system as a 5-tuple consisting of Input, Control, Output, Mechanism, and Process, which is the underlying system-view in the well-know IDEF0 diagramming technique. In particular, this taxonomy addresses the VE extended lifecycle that implies the use of a meta-organization called Market of Resources, as an original contribution to the VE theory and practice. The taxonomy presented does not repeat what the literature already includes, or the commonplaces, and it is constructed in a way to be easily complemented with other VE partial taxonomies that may be found in literature. Some suggestions for extensions to other interrelated domains (as evolution leaves taxonomies in an open or incompleteness state) are given in the text.

Direct communication versus virtual communication in virtual teams

Several studies suggest that computer-mediated communication can lead to decreases in group effectiveness and reduce satisfaction levels in terms of trust and comfort of its users. Supported by an experiment, where the emotional or affective aspects of communication were tested with the experimentation of two architectures, Direct Communication Architecture (DCA) and the Virtual Communication Architecture (VCA) this paper validates the thesis that, from the users’ perspective, there is no opposition to the acceptance of virtual environments and interfaces for communication, and that these environments are able to cope with the reconfiguration dynamics requirements of virtual teams or client-server relations in a virtual enterprise operation.

Money laundering and virtual money: the bitcoin example

Money laundering operations faced multiple changes and become more complex, in line with financial innovation. Often, regulation does not follow that innovation, giving opportunity to take advantage of thes e gaps in less lawful activities. The bitcoin is a virtual currency that has grown significantly, both in value and in volume of transactions, in recent years. The dimension of the phenomenon led to an increasing surveillance from the financial supervisors . We search for evidence of the relationship between money laundering and transactions carried out in bitcoins, the most popular virtual currency at the moment. We analyse the official publications relating the two themes, academic research and the notori ety within the international media. The attitudes toward the bitcoin are diverse, but all share concerns about its future impact. Some sparse evidence indicates that bitcoin may be an opportunity for money laundering, however more data is required.

Comunidade de práticas virtual para investigadores : um projeto em desenvolvimento

As Comunidades de Prática fomentam a aprendizagem, transmissão e produção de conhecimento na organização. Contudo, esta perspetiva é ainda pouco desenvolvida nas comunidades online de e para investigadores. Neste artigo, apresenta-se o plano de desenvolvimento de uma Comunidade de Prática, desenvolvida na plataforma Moodle e num grupo no Facebook, para investigadores na Universidade Aberta, alicerçado num enquadramento teórico do tema, com o qual se pretende reforçar a comunicação online e cooperação entre os investigadores, potencializando a coesão e melhoria de práticas a nível da investigação. Pela análise de entrevistas realizadas aos investigadores e das dinâmicas geradas no grupo de Facebook verifica-se interesse no desenvolvimento de projetos de investigação e preferência pelo trabalho em equipa, apesar da falta de financiamento, tempo ou apoio. Apurou-se ainda um aumento de interações em publicações dos próprios investigadores, sendo que, em média, apenas 21 dos 43 membros do grupo visualizam as publicações, havendo maior ou menor interesse conforme o tipo de publicação feita.

A bot spooler architecture to integrate virtual worlds with e-learning management systems for corporate training

Joining efforts of academic and corporate teams, we developed an integration architecture - MULTIS - that enables corporate e-learning managers to use a Learning Management System (LMS) for management of educational activities in virtual worlds. This architecture was then implemented for the Formare LMS. In this paper we present this architecture and concretizations of its implementation for the Second Life Grid/OpenSimulator virtual world platforms. Current systems are focused on activities managed by individual trainers, rather than groups of trainers and large numbers of trainees: they focus on providing the LMS with information about educational activities taking place in a virtual world and/or being able to access within the virtual world some of the information stored in the LMS, and disregard the streamlining of activity setup and data collection in multi-trainer contexts, among other administrative issues. This architecture aims to overcome the limitations of existing systems for organizational management of corporate e-learning activities.
