Esta dissertação apresenta um projecto em engenharia de software para o desenvolvimento e implementação ·De um módulo parte integrante da plataforma XEO, denominado XEOReports. Este módulo destina-se à construção de relatórios dinâmicos, no formato. pdf tendo como base ecrãs de edição da plataforma XEO. Foi utilizada uma plataforma de geração de relatórios em diversos formatos, de nome JasperReports, de forma a que o módulo desenvolvido fosse a integração entre as duas plataformas, XEO e JasperReports. O desenvolvimento deste módulo foi feito tendo em conta os requisitos que a plataforma jasperReports apresentava para a geração de relatórios tendo como base os ecrãs da plataforma XEO. O estudo foi feito respeitando a metodologia de desenvolvimento de software UML, respeitando as boas práticas de desenvolvimento de software a ela inerentes. ABSTRACT; This thesis consists in a software engineering project that deals with the development, functioning and implementation of the XEOReports module, which later became a component of the XEO platform. The XEOReports module aims the construction of dynamic reports in the Portable Document Format (PDF), based on edition screens of the XEO platform. JasperReports, an open source reporting engine, which generates reports in several file formats, was also used in the project development. Therefore, the XEOReports module is the result of the two platforms integration, namely XEO and JasperReports. It is also important to refer that this study took into account the JasperReports platform requirements in the creation of reports based on edition screens of the XEO platform. Moreover, the development methodology of the UML software, as well as the good development software practices inherent in it, were respected and followed in the progression of this project.

In order to turn more efficient the heating of class rooms in the lower floor of the old building of the University of Évora (a XVI century building), five drillings were organised inside the area of the university (Figure 1). The purpose was to use the temperature differential of groundwater in relation to air, by means of a heat exchanger, and use this process to heat the rooms using less energy, turning the heating process less expensive. The wells were drilled in fractured rocks (gneisses), and the purpose was to locate them at least around 100 m one from each other, whilst trying to have a hydraulic connection in-between. From the five initial wells, four were successful in terms of productivity, but just two of them (RA1 and RA2) proved to be hydraulically connected. The wells were equipped with screens for all their drilled depth (100 m), except for the first six meters and some two or three pipes of six meters each, to allow space for the installation for submersible pumps. The length of the installed screens guarantees a good efficiency of the system. In the wells with no connection, the heating system can work using each single well for abstraction and injection, but the process is much less efficient than in the cases where interaction between wells is possible through the rock’s fracture network.
