Three-Dimensional Electrocardiography in the RatRice, Peter J. 01 January 1992 (has links)
Three-dimensional electrocardiography with computerized analysis provides a means to rapidly collect and quantitatively analyze electrocardiographic data from rats. Electrical activity at each point in time can be expressed quantitatively as a vector with magnitude and direction. Rats are fitted with plate and needle electrodes in three mutually perpendicular axes: X (right to left), Y (rostral to caudal), and Z (ventral to dorsal). Electrocardiographic signals are recorded on paper and also collected at 1000/sec using an IBM-compatible computer equipped with a fast A/D convertor. Signals are analyzed using an interactive program written in Turbo PASCAL which transforms data into an array consisting of vector magnitude and direction at each time point. The data are further used to produce both a tabular report and graphic output. This method retains simplicity while extending the accuracy of electrocardiographic (ECG) measurement. It literally adds another dimension of information to the three-lead ECG most commonly measured in rats.

[en] A DIGITAL CONTROLLER FOR A GONIOMETER / [pt] CONTROLE DE UM GONIÔMETRO DE DIFRAÇÃOMOISES HENRIQUE SZWARCMAN 30 January 2007 (has links)
[pt] Este trabalho descreve parte de um controlador digital
para um goniômetro de difração, usado na determinação dos
elementos presentes em uma amostra de material por meio de
difração de raios X.
O processo de análise é sumariamente descrito, de modo a
evidenciar as funções que o controlador deve realizar.
Baseado nestas funções, a estrutura do programa de
controle é discutida e os problemas de sua implementação,
em um microcomputador de uso geral, são examinados.
Os problemas de entrada e saída de dados dão discutidos e
as rotinas de conversão são apresentadas. Finalmente, os
problemas de interface de circuitos e suas soluções são
apresentadas e discutidas. / [en] This work describes part of a digital controller for a
goniometer, used to determine the components that are
present in a material sample by means of diffraction of X
rays.
The process of analysis is briefly show to make clear the
performance expected for the controller. Based in the
functions the controller should achieve, the Control
Program structure is argued and the problems of its
implementation in a microcomputer are examined.
The problems that apper in input-stream data and output
data-stream are ergued and conversion routines are
presented. Finaly, the problems of interface of circuits
and their solutions are presented andargued.

[en] CENTRAL COMPUTER OF A MICROCOMPUTER NETWORK CALLED MULTIPUC / [pt] COMPUTADOR CENTRAL DE UM SISTEMA DISTRIBUÍDO DE MICROCOMPUTADORES - MULTIPUCSHEILA DORFMAN LAUFER 18 April 2007 (has links)
[pt] Este trabalho faz parte do projeto de um sistema
distribuído de microcomputadores, MULTIPUC, em
desenvolvimento no Laboratório de Engenharia e Sistemas de
Computação (LESC) DA PUC/RJ.
Neste trabalho descreve-se o projeto e desenvolvimento de
duas máquinas:
- O computador Central do MULTIPUC
- controlador Inteligente de Comunicação
O computador Central do MULTIPUC é baseado no
microprocessador 8086 da Intel e sua finalidade é
gerenciar os acessos dos microcomputadores satélites do
MULTIPUC às memórias secundárias e dispositivos
periféricos e ainda, a comunicação dos satélites entre si
e com máquinas externas ao MULTIPUC.
O Controlador Inteligente de comunicação é um processador
dedicado à tarefas de comunicações externas e é baseado no
microprocessador 8085 da Intel e no controlador
programável de DMA 8237 da Intel. / [en] This work is part of a microcomputer network Project
called MULTIPUC which hás been developed at the
Laboratório de Engenharia e Sistemas de Computação (LESC).
This work is a description of the design and
implementation of two machine:
- The MULTIPUC Central Computer
- The communication Intelligent Controller
The MULTIPUC Central Computer is based on the Intel 8086
microprocessor. Its main purpose is to manage the accesses
of the MULTIPUC microcomputers called SATÉLITES to
secundary memories and peripherals and also the
communication of SATÉLITES among themselves and other
computeres external to MULTIPUC.
The communication Inteligent Controller is a processor
dedicated to tasks of external communications and is based
on the Intel 8085 microprocessor and the Intel 8237,
programmable DMA Controller.

[en] FUNCTIONAL TEST OF MICRO-02 / [pt] TESTE FUNCIONAL DO MICRO-02LUCIANO SERGIO BRITO NICOLAU DA COSTA 11 June 2007 (has links)
[pt] Este trabalho consiste na apresentação das rotinas de
testes que forma desenvolvidas visando a verificação do
funcionamento do microcomputador desenvolvido no Grupo de
Eletrônica da PUC (GELUC): o MICRO-02
Essas rotinas de testes constam de microprogramas e também
de programas realizados com o auxílio do repertório de
instruções do microprocessador central (CPU - 8008) do
microcomputador. Elas visam apenas o teste funcional do
sistema não se preocupando com a localização da falha.
Entretanto, através dos resultados de partes já testadas,
pode-se tirar conclusões que permitam um grau de
localização mais preciso da falha. / [en] This work consists of a presentation of test routines that
were developed taking into account the verification of the
Microcomputer´r functioning developed by GRUPO DE
ELETRÔNICA DA PUC (GELUC): the MICRO-02.
These test routines consist of microprograming and also of
programs developed with the aid of the instructions report
of the microcomputer´r central microprocessor (CPU -
8008). They only intend the functional test of the system,
and do not take into account the localization of the
failure. However, through the results of parts which have
already been tested, one can have conclusions that allow a
more precise degree of localozation of the failure.
