Usage of enterprise modeling processes and information systems design to forecast demand

Managing the great complexity of enterprise system, due to entities numbers, decision and process varieties involved to be controlled results in a very hard task because deals with the integration of its operations and its information systems. Moreover, the enterprises find themselves in a constant changing process, reacting in a dynamic and competitive environment where their business processes are constantly altered. The transformation of business processes into models allows to analyze and redefine them. Through computing tools usage it is possible to minimize the cost and risks of an enterprise integration design. This article claims for the necessity of modeling the processes in order to define more precisely the enterprise business requirements and the adequate usage of the modeling methodologies. Following these patterns, the paper concerns the process modeling relative to the domain of demand forecasting as a practical example. The domain of demand forecasting was built based on a theoretical review. The resulting models considered as reference model are transformed into information systems and have the aim to introduce a generic solution and be start point of better practical forecasting. The proposal is to promote the adequacy of the information system to the real needs of an enterprise in order to enable it to obtain and accompany better results, minimizing design errors, time, money and effort. The enterprise processes modeling are obtained with the usage of CIMOSA language and to the support information system it was used the UML language.

Synchronizing Brazilian Sign Language (LIBRAS) on videos for Open Digital TV with educational purposes

The TV is a potential midia of communication that affects all social classes and it is available in 98% of Brazilian homes. It has been used as a distributor of educational materials since the 1950s. By 2016 the Open Digital TV (ODTV) in Brazil might cover the entire national territory, replacing the TV with analog signals. Concerns about accessibility for People with Special Needs (PSN) in that media have become more intense since the 1990s worldwide. In Brazil, it is estimated 24.6 million of PSN, 23% of them having some type of hearing loss. Of these, 2.9% are reported as deafs. Brazilian Sign Language (LIBRAS) is considered the first literacy language for deaf people in Brazil. In this context, this paper presents a proposal to facilitate the generation of educational content for ODTV based on two components. One is called SynchrLIBRAS and allows subtitles synchronization in Portuguese and a LIBRAS translator window of videos downloaded from the Web. The second component allows the visualization of this content through the Brazilian System of Digital TV and IPTV - environments that implement the middleware Ginga-NCL. The main focus of this paper is the presentation of the first component: SynchrLIBRAS. This proposal has educational purposes, contributing to teach LIBRAS to people who may collaborate with social inclusion of the deaf people.

Quantum entanglement and information: The effect of entropy revisited

In non-extensive statistical mechanics [14], it is a nonsense statement to say that the entropy of a system is extensive (or not), without mentioning a law of composition of its elements. In this theory quantum correlations might be perceived through quantum information process. This article, that is an extension of recent work [4], is a comparative study between the entropies of Von Neumann and of Tsallis, with some implementations of the effect of entropy in quantum entanglement, important as a process for transmission of quantum information. We consider two factorized (Fock number) states, which interact through a beam splitter bilinear Hamiltonian with two entries. This comparison showed us that the entropies of Tsallis and Von Neumann behave differently depending on the reflectance of the beam splitter. © 2011 Academic Publications.

DOCPAL country population documentation development (the next phase of the DOCPAL project presently funded under IDRC Grant No 3-P-75-0101); a request to the Information Science Division of the IDRC, Ottawa, Canada

El proyecto para el desarrollo de las capacidades de los paises en el area de documentacion en poblacion constituye la segunda fase de las actividades del DOCPAL (1978-1980) y tiene como objetivos centrales: a).ayudar a las instituciones comprometidas en actividades de poblacion, en alrededor de 4 paises anualmente, a mejorar sus capacidades e infraestructura; b).posibilitar a aquellos paises mejor dotados para que se constituyan en centros miembros de DOCPAL; c).mejorar, extender y continuar la entrega de servicios de nivel regional a los paises; d).mejorar y mantener los sistemas computarizados de procesamiento de la informacion. La descripcion detallada de estas actividades constituye el fundamento para la solicitud de fondos al IDRC durante el periodo senalado

The software and information technology services industry: An opportunity for the economic autonomy of women in Latin America

The objective of this report is to understand the rationality that underpins public and business policies for promoting the IT and SIS industries and to determine whether they incorporate gender equality and/or provide incentives for women’s participation. The report also explores how this group of women is symbolically constructed within the firms, what issues are emphasized by the women themselves and what solutions or resources they propose for overcoming the problems. It then contrasts this discourse and intervention with the experiences, visions and demands of women leaders in the SIS sector. For this purpose, the policies, programmes and best practices of Europe are analysed and compared with instruments currently in place in Latin America and the Caribbean, in terms of their specific characteristics and degree of progress. Special attention is given to the cases of Argentina, Costa Rica and Colombia.
