Java applets for a WWW-HTML-based course in power electronics

This paper introduces Java applet programs for a WWW (world wide web)-HTML (hypertext markup language)-based multimedia course in Power Electronics. The applet programs were developed with the purpose of providing an interactive visual simulation and analysis of idealized uncontrolled single-phase, and three-phase rectifiers. In addition, this paper discusses the development and utilization of JAVA applet programs to solve some design-oriented equations for rectifier applications. The major goal of these proposed JAVA applets was to provide more facilities for the students increase their pace in Power Electronics course, emphasizing waveforms analysis, and providing conditions for an on-line comparative analysis among different hands-on laboratory experiences, via a normal Internet TCP/IP connection. Therefore, using the proposed JAVA applets, which were embedded in a WWW-HTML-based course in Power Electronics, was observed an important improvement of the apprenticeship for the content of this course. Therefore, the course structure becomes fluid, allowing a true on-line course over the WWW, motivating students to learn its content, and apply it in some applications-oriented projects, and their home-works.

Caracterizaçõ da linguagem na síndrome do X-frágil: estudo bibliográfico.

BACKGROUND: X-Fragile Syndrome. AIM: To compile information about the language, cognitive and behavior alterations in the X-Fragile Syndrome, using the results of previously published studies and to present the standardized instruments used as testing materials. CONCLUSION: studies used formal and informal testing to assess language. The results present variability regarding the linguistic deficits, which are influenced by the level of the cognitive deficit and behavior alterations. Alterations of the oral praxes and of speech articulation are also expected.

Educational Java applets get in power electronics labs

This paper presents Java applet programs for a WWW (world wide web)-HTML (hypertext markup language)-based multimedia course in basic power electronics circuits. These tools make use of the benefits of Java language to provide a dynamic and interactive approach to simulate steady-state idealized rectifiers (uncontrolled and controlled; single-phase and three-phase). In addition, this paper discusses the development and the use of the Java applet programs to assist the teaching of basics rectifier power electronics circuits, and to serve as a first design tool for basics power electronics circuits in the experiments of the laboratories. In order to validate the developed simulation applets, the results were confronted with results obtained from a well-know simulator package PSPICE. © 2005 IEEE.

Towards a java bytecodes compiler for nios II soft-core processor

Reconfigurable computing is one of the most recent research topics in computer science. The Altera - Nios II soft-core processor can be included in a large set of reconfigurable architectures, especially because it is designed in software, allowing it to be configured according to the application. The recent growth in applications that demand reconfigurable computing made necessary the building of compilers that translate high level languages source codes into reconfigurable devices instruction sets. In this paper we present a compiler that takes as input the bytecodes generated by a Java front-end compiler and generates a set of instructions that attends to the Nios II processor instruction set rules. Our work shows how we process Java bytecodes to the intermediate code, in the Nios II instructions format, and build the control flow and the control dependence graphs. © 2009 IEEE.

Intervenções em linguagem escrita: Uma revisão da literatura com vistas à redução dos transtornos funcionais de aprendizagem

The importance reading and writing and being able to use these skills in a variety of situations is an absolute reality. In our society in which reading and writing are widely used, Brazil still faces severe problems with literacy, as revealed in literacy statistics and in the large number of students with learning disabilities. Thus, our text aims to present a survey of the research that focuses on intervention programs highlighting the needs of this group, with special attention on the use of narrative or storytelling. Specific criteria were established, the main one being the period of the publications (2000 to 2010). The results of the analysis of 15 texts showed that intervention is the most neglected area. International literature presents concerns related to scientific rigor or greater control of variables related to ongoing programs, as well as measures for generalizing the effective use of these programs, within verbal communities, with special focus on schools. Our revision enabled us to conclude that, even though production on written language is large, international literature is much more expressive with reference to intervention programs. Furthermore, in both national and international literature, production concerning the understanding of written language processes of acquisition and development prevails.

Abreviar (distâncias) na internet, conectar-se ao mundo (na linguagem)

This article aims to investigate the abbreviations used on chats by web-surfers between 15 and 20 years old. The material consists of two virtual conversations of about 60 minutes each. We believe that this linguistic process occurs due to the physical distance that separates affectively the web-surfers by modifying already said utterances in written practices characterized by short time of interaction. This abbreviation process, known as a characteristic of the so called internetês, is not considered as a simple attempt to cut the words, but as a resource that presents linguistics' regularity. Therefore, the theory of phonological syllable is used as a tool in order to verify the process that forms possible abbreviations used on chats. It is believed that, based on the study of the syllable structure, the choice of the graphemes abbreviation may be assessed based on the writing heterogeneity, since the writer might not only use oral/spoken practices but also literate/written ones so as to produce utterances that emerge in the contemporaneity.

Fluxos de informação e linguagem em ambientes organizacionais

Information flows are formed naturally or formally induced in organizational settings, passing from the strategic level to operational level, reflecting, and impacting in the processes that make up the organization, including the decision-making process and therefore the action strategies of organization. The management of organizational environments based on information requires careful attention to various kinds of languages used for communication between sectors and employees of the organization, whose goal is to share, disseminate and socialize the information produced in this environment.

A linguagem, o texto e o documento no contexto da ciência da informação

The relation among the concepts text, document and information is discussed, with the aim of clarifying the concept of document, with a focus in the field of economic information organization and management. A document is a medium in which information is recorded and manifested. A document is, thus, material, has a purpose, can be organized and treated for its improved dissemination, and has a specific subject and context.

Desenvolvimento de interface amigável de rotina em linguagem c++ para o processamento aritmético e estatístico de dados censitários

A routine was developed in C++ for the processing of social and environmental census data acquired by the Brazilian Institute of Geography and Statistics (IBGE). The routine employs a simple graphical environment. The data generated are presented in a tabular format, which facilitates a broad and objective view of the values, and provides a convenient means of querying the database. The source code used to develop the routine permits updates and changes, as required by the user. Statistical and mathematical analysis enables the generation of social and environmental indicators, together with quantitative and qualitative classification of the socio-environmental quality of the region analyzed. As an example, the routine was applied using census data for the city of Sorocaba (São Paulo State, Brazil), including conditions of household occupation, water supply, sanitation, level of education, income, and other factors. It is envisaged that the proposed analytical model will assist professionals from different fields of research and teaching to develop urban planning and management strategies.
