Apresenta-se um pré-processador para análise de pavimentos de edifícios via método dos elementos finitos desenvolvido como um aplicativo do ambiente Windows. O programa é interativo, permitindo identificar problemas de imediato na criação do modelo a ser estudado. Possui recursos gráficos básicos para a definição geométrica da estrutura. A saída de dados é programável para que o pré-processador não se prenda a um só programa de cálculo. Assim, os mesmos dados de uma estrutura podem ser analisados por diferentes programas de cálculo o que possibilita a escolha do programa mais adequado, dependendo do tipo de análise desejado. O aplicativo tem recursos para definir elementos finitos de barra e placa. Como o número desses elementos normalmente é grande, eles são gerados de uma forma automatizada. / lt is presenting a Windows preprocessar for building slab analysis by Finite Element Method. lt is an interactive program, allowing problems to be identified while the model is generated. It has graphical resources to define the structure. The program output is defined by the user; therefore it is possible to use the preprocessar with many other finite element programs. This allows the engineer to choose the appropriate program depending on the kind of analysis is wanted. The program can define frame and shell finite elements. As slabs usually need large numbers of these elements to be properly analyzed, they are generated using automatic meshing.

<p>NMD 100 is a notes and media dispensing machine, manufactured by De La Rue Ltd, located in Flen, Sweden. The customers, mainly bank offices, have expressed a need for a more comprehensive description of errors occurring from time to time in their machines. In order to acquire a BSc-degree in Computer and Electronics Technology at the University of Linköping I have carried out a diploma work, regarding new computer programs to fulfil the customers’ wishes. The machine NMD 100 is connected to its PC through handshaking. From the PC, the personnel can give orders regarding desired actions to the NMD 100. In turn, the NMD will respond to the PC. Inside the NMD, the Note Stacker is equipped with a great number of sensors. They control that the bundle of notes, delivered to the ATM customer is correct, regarding the number of notes and denomination. Notes that in any way are not immaculate will be sent to the Reject Vault. </p><p>If internal errors or warnings occur in the NMD, a code consisting of 8 digits is sent to the PC. The location of the error or warning is defined by the last 4 digits. The scope of my work is to define and present this information. For this purpose the company uses the program language C++ and the tool Borland C++ Builder 6. In particular, the program NMDW-Test is used to send commands from the PC to the NMD. After having studied the above programs, I was able to write new programmes for error detection, interface and installation. After program testing, the company accepted the result of my work.</p>

This thesis has been a study in memory management in C/C++, with practical work in finding and solving memory leaks in a large project. A background theory of C++ and memory management has been presented along with the memory problems that can arise in development in C/C++. Several topics in minimizing memory problems with using inbuilt C++ libraries and the Boost libraries have also been presented. There is also an overview of the PLC-Opt 2.2 Beta application and its inner workings. The method was to learn all about memory management and solve the memory leaks in PLC-Opt. The results showed that there were approximately 28.000 instances of memory leaks and the end result showed that approximately 700 instances of leaks remained unresolved. A list with clues of the remaining memory leaks was provided in the Future work chapter.
