Critérios de teste estrutural baseados em análise de fluxo de dados têm sido propostos para o teste de unidade; não existe uma ferramenta de teste que apóie a aplicação desses critérios para programas implementados na linguagem FORTRAN-77. No DCA/FEE/UNICAMP foi desenvolvida uma ferramenta de teste que apóia a aplicação dos Critérios Potenciais Usos PU (uma famíl ia de critérios de fluxo de dados), denominada POKE-TOOL, configurável para diversas linguagens e que está operacional para as linguagens C e COBOL. Este trabalho apresenta a configuração da POKE-TOOL para a linguagem FORTRAN-77. A POKE-TOOL/versão FORTRAN-77 foi vai idada parcialmente com sua aplicação no teste de um conjunto de programas selecionados da literatura; os resultados dessa atividade são também apresentados e brevemente analisados neste trabalho / Abstract: Testing activities applied manually are as error-prone as other software development activities. Data-flow based structured testing criteria have been proposed for unit testing; there is no testing tool supporting these criteria for programs implemented in the FORTRAN-77. At DCA/FEE/UNICAMP a configurable testing tool, named POKE- TOOL., which supports the application of the Potential Uses Criteria (a data-flow based testing criteria family) has been developed and 15 operational for languages C and COBOL. This work presents the configuration of POKE-TOOL for FORTRAN-77. POKE-TOOL/version FORTRAN-77 has been partially validated using a program set selected from the Iiterature; the results of this activitv are also presented and briefly analysed in this work / Mestrado / Automação / Mestre em Engenharia Elétrica

The purpose of this thesis was the development of a generalized structural-dynamics computer program to calculate the response of multi-degree-of-freedom systems. The user of this computer program, having a limited background in matrix algebra and vibrational analysis, can gain numerical and graphical information concerning the dynamic response of multi-degree-of-freedom structures. The user, with a minimal amount of FORTRAN experience, will find this thesis ideally suited for his needs.

The solution to a set of simultaneous equations is of the form A-1 B = X where A-1 is the inverse of A in the equation AX= B. The purpose of this study is to obtain an exact A-1 through the use of rational arithmetic, and to study the behavior of rational numbers when used in arithmetic calculations. This study describes a matrix inversion program written in SPS II, utilizing the concept of rational arithmetic. This program, using the Gaussian elimination matrix inversion method, is compared to the same method written in Fortran. Gaussian elimination was used by this study because of its simplicity and speed of inversion. The Adjoint method was ruled out because of its complexity and relative lack of speed when compared with Gaussian elimination. The Fortran program gives only an approximate inverse due to the rounding error while the rational arithmetic program gives an exact inverse.

This thesis will present the effects of the orbital debris evolution in two key areas: the geosynchronous disposal orbit regime known as “graveyard” and the two geopotential wells found in 105◦ W and 75◦ E longitude bins. After developing a GEO specific orbit propagator for NASA Johnson Space Center’s Orbital Debris Of- fice, collisions were simulated throughout these regimes using a low velocity breakup model. This model considered the effects of perturbations particularly non-spherical Earth effects (specifically sectorial and zonal harmonics), lunar effects, third body effects and solar radiation pressure effects. The results show that CDPROP does well in simulating the presence of the Eastern and Western geopotential wells, as well as catching drifting GEO objects. It does not do as well in catching East-West trapped objects. Three collision test cases were then simulated in graveyard and the East and West geopotential wells.
