This study, inserted in the realm of productive landscape, analyses the risks and advantages of growing fruit trees for the protection and recovery of the bottom of urban valleys. This questioning has been done by the analysis of technical works that approach correlated subjects and from results of carried through interviews with professionals in diverse areas of knowledge. In these interviews professionals had been requested to present their interpretations according to the possibilities and limitations of the adoption of techniques of productive landscape, as and strategy to protect and recovery of lands located on the border of the urban s waters. It has as general objective, to contribute for the improvement of the water quality and the environment conditions of the water s courses insert into urban mesh, and, as an specific objective, contribute for the formulation of landscape s projects a of protection and recovery of urban hydrographic basis where are foreseen the landscapes qualifications of the lands in the bottom of valleys. / A busca de alternativas para a prote??o e recupera??o dos bens naturais, em especial, a ?gua em seu local de origem, tem sido tem?tica de discuss?o sob diferentes enfoques, nas diversas ?reas de conhecimento. Neste estudo, que se insere na tem?tica do Paisagismo Produtivo, questiona-se a respeito de riscos e vantagens no plantio de esp?cies frut?feras na prote??o e recupera??o de fundos de vale urbanos. Esse questionamento foi feito a partir da an?lise de trabalhos t?cnicos que abordam temas correlatos e a partir dos resultados de entrevistas realizadas com profissionais de diversas ?reas de conhecimento. Nestas entrevistas, os profissionais foram solicitados a apresentar suas interpreta??es quanto ?s possibilidades e limita??es da ado??o de t?cnicas de paisagismo produtivo, como estrat?gia para prote??o e recupera??o dos terrenos situados junto aos corpos de ?gua urbanos. Tem-se, como objetivo geral, contribuir para a melhoria da qualidade da ?gua e das condi??es ambientais dos cursos de ?gua inseridos no tecido urbano e, como objetivo espec?fico, contribuir para a formula??o de projetos de prote??o e recupera??o de microbacias hidrogr?ficas urbanas, em que est?o previstos as qualifica??es paisag?sticas dos terrenos de fundo de vale.

Biometric systems are being increasingly used, from daily entertainment to critical applications such as security access and identity management. It is known that biometric systems should meet the stringent requirement of low error rate. In addition, for critical applications, the security and privacy issues of biometric systems are required to be concerned. Otherwise, severe consequence such as the unauthorized access (security) or the exposure of identity-related information (privacy) can be caused. Therefore, it is imperative to study the vulnerability to potential attacks and identify the corresponding risks. Furthermore, the countermeasures should also be devised and patched on the systems. In this thesis, we study the security and privacy issues in biometric systems. We first make an attempt to reconstruct raw biometric data from biometric templates and demonstrate the security and privacy issues caused by the data reconstruction. Then, we make two attempts to protect biometric templates from being reconstructed and improve the state-of-the-art biometric template protection techniques.

This diploma thesis is focused on the development of a new backup plan and its implementation. In introductory part of the thesis I explore the theorethical backround of data backup and data management. Next part is dedicated to analysis of current state and investor requierements. Last part is aimed to implementation of new backup plan with focusing on economic and quality point of view. Besides concept and realization of backup plan the concept of the backup directive is created .
