This thesis deals with the impact of the reconstruction on the market value of an apartment unit in a particular location. The first part of the thesis explains the terms that relate to the issue. In the second part the impact of the reconstruction on the price of the unit is examined. Firstly, it is evaluated analytically and statistically based on data from the created database and then specifically on two apartment units that have been reconstructed. These were valued in three ways - the comparative way and cost way without price adjustment coefficient according 441/2013 Sb. and method of the direct comparison. The thesis compares the value of these units before and after the reconstruction. It also deals with the evaluation of the investment when it compares the costs of reconstruction with the increase of market value of the real estate.

[pt] Projetistas de sistemas de comunicações ópticas necessitam estimar o coeficiente de PMD dos enlaces ópticos visando determinar a correspondente penalidade de potência do enlace. Os valores de PMD nas fibras variam aleatoriamente, conseqüentemente a determinação da PMD dos enlaces deverá ser calculada através de metodologias estatísticas. Esta dissertação contém um estudo sistemático da estimação do coeficiente de PMD das seções amplificadas de 02 backbones. Três 03 técnicas estatísticas: Técnica de Monte Carlo, Modelo Gama e Teorema do Limite Central Generalizado, recomendadas pelo Método 1 da norma TIA/EIA TSB 107 foram usadas e os resultados comparados com os valores medidos em campo destas seções. Os resultados das avaliações realizadas mostraram que a metodologia apresentada por esta recomendação induz a uma superestimação do coeficiente de PMD do enlace devido a limitação dos equipamentos de medição e conseqüentemente a uma superestimação da penalidade prevista. Esta superestimação deve-se ao fato da PMD das fibras estar abaixo do limite de sensibilidade dos equipamentos de medida comercialmente disponíveis. A estimação do coeficiente de PMD de enlaces requer então a utilização de equipamentos de medida mais precisos (ainda não disponíveis) ou corrigir esta metodologia de cálculo para a estimação da PMD dos enlaces ópticos com a utilização de fibras/cabos de maior comprimento. / [en] Optical system designers need to estimate the expected PMD coefficient of the links in order to calculate the corresponding power penalty. Fiber PMD values varies randomly, therefore the link PMD estimation shall be calculated by statistical methodologies. This thesis presents a systematic study of PMD estimation of the amplified spans of two backbones. Three statistical techniques: Monte Carlo Technique, Gamma Model and Generalized Central Limit Theorem, recommended by Method 1 from TIA/EIA TSB 107 Guideline were used and the results compared with the field measurement values of these spans. Evaluation results showed that this methodology cause an overestimation of the link PMD coefficient due to a limitation of the measurement eqquipments and consequently an overestimation of the power penalty. This overestimation is due to the fact that fiber PMD is bellow of the resolution limit of the commercially available measurement equipments. Link PMD coefficient estimation needs the use of more precise measurement equipment (Not available yet) or to correct this calculus methodology for the optical link PMD estimation with the use of longer fibers/cables.

La localisation de dégâts basée sur les mesures de vibrations est devenue un axe de recherche important pour la surveillance de la santé structurale (SHM). En particulier, la Stochastic Dynamic Damage Locating Vector (SDDLV) est une méthode de localisation des dégâts basée sur le couplage entre un modèle aux éléments finis (FE) de la structure et des paramètres modaux estimés à partir des mesures dynamiques en excitation ambiante dans les états structuraux sain et endommagé, interrogeant les changements dans la matrice de transfert. Dans la première contribution, la méthode SDDLV est étendue avec une approche statistique conjointe utilisant plusieurs ensembles de modes, surmontant la limitation théorique sur le nombre minimal de paramètres. Un autre problème traité est la performance de la méthode en fonction du choix de la variable de Laplace où la fonction de transfert est évaluée. Une attention particulière est accordée à ce choix et à son optimisation. Dans la deuxième contribution, l'approche Influence Line Damage Location (ILDL), complémentaire à l’approche SDDLV est étendue avec un cadre statistique. Dans la dernière contribution, une approche de sensibilité pour les petits dommages est développée en fonction de la différence des matrices de transfert, permettant la localisation des dommages par des tests statistiques dans un cadre gaussien, et en plus la quantification des dommages dans une deuxième étape. Enfin, les méthodes proposées sont validées sur des simulations numériques et leurs performances sont testées dans de nombreuses études de cas sur des expériences de laboratoire. / Vibration-based damage localization has become an important issue for Structural Health Monitoring (SHM). Particularly, the Stochastic Dynamic Damage Locating Vector (SDDLV) method is an output-only damage localization method based on both a Finite Element (FE) model of the structure and modal parameters estimated from output-only measurements in the reference and damaged states of the system, interrogating changes in the transfer matrix. Firstly, the SDDLV method has been extended with a joint statistical approach for multiple mode sets, overcoming the theoretical limitation on the number of modes in previous works. Another problem is that the performance of the method can change considerably depending on the Laplace variable where the transfer function is evaluated. Particular attention is given to this choice and how to optimize it. Secondly, the Influence Line Damage Location (ILDL) approach which is complementary to the SDDLV approach has been extended with a statistical framework. Thirdly, a sensitivity approach for small damages has been developed based on the transfer matrix difference, allowing damage localization through statistical tests in a Gaussian framework, and in addition the quantification of the damage in a second step. Finally, the proposed methods are validated on numerical simulations and their performances are tested extensively in numerous case studies on lab experiments.
