KRATOCHVÍL, Jakub January 2017 (has links)
There are two main parts in this thesis. In the first part is summarized an overview of basic concepts and requisites we can meet with valuation on real estate market, if we use the valid applicable law and decree about valuation. The emphasis was put on the specifics of the market value and detected value and their comparison. The aim of the second part was make a local investigation in selected real estates in locations Pacov and Lukavec. Then I did careful valuation according to the methodology for determine the market value and detected value and then compared results.

Development of a method for predictive calculations density of ionic liquids in a wide range of temperature and pressure / Desenvolvimento de um mÃtodo preditivo para cÃlculos de massa especÃfica de lÃquidos iÃnicos em um amplo intervalo de temperatura e pressÃo.

CoordenaÃÃo de AperfeÃoamento de Pessoal de NÃvel Superior / Ionic liquids are compounds of considerable interest due to their unique physicochemical properties. A detailed knowledge of these properties is of great importance. In particular, the liquid density is a very important property required in many design problems and, therefore, in process simulation . Experimental measurements of this property is not viable for all the existing ionic liquids . Therefore, development of new methods for its estimation is essential. In this work , a new group contribution model capable of estimating ionic liquids density over a wide range of temperatur e (251.62 â 473. 15 K) is proposed. This method ( â GCVOL - IL â ) is an extension of a reliable existing method ( âGCVOL - OL - 60â ) able to estimate the same property for organic molecular compounds at several temperatures and atmospheric pressure . Estimation of density at higher pressures (up to 300 MPa) was performed by the use of a Tait - type equation. A large databank containing 21845 experimental density data for 863 pure ionic liquids and 994 experimental data for 15 different binary mixtures of these com pounds has been applied in the development of this work . The results presented indicated that the model was able to estimate the volumetric behavior (T, P, ρ ) of various ionic liquids ( including policationic species) and of binary mixtures containing these compounds (x, T, ρ ) . The method has been compared to the best existing group contribution models able to estimate the same property. The analysis of different criteria encourage s the application and implementation of the proposed method in process simulators. / LÃquidos iÃnicos sÃo compostos possuidores de uma sÃrie de caracterÃsticas fÃsico-quÃmicas desejÃveis para diferentes aplicaÃÃes industriais. O conhecimento das suas propriedades, sobretudo da massa especÃfica, à fundamental para que eles sejam aplicados em simuladores de processos. A determinaÃÃo experimental de tal propriedade à impraticÃvel para todos os lÃquidos iÃnicos existentes, de forma que mÃtodos capazes de estima-las sÃo requeridos. Neste trabalho, à apresentado um novo mÃtodo de contribuiÃÃo de grupos capaz de estimar a massa especÃfica dessa classe de compostos em um amplo intervalo de temperatura (251,62 â 473,15 K), o qual foi denominado âGCVOL-ILâ. O mÃtodo proposto à uma extensÃo do modelo âGCVOL-OL-60â, o qual à capaz de estimar satisfatoriamente a massa especÃfica de compostos orgÃnicos moleculares a diferentes temperaturas e à pressÃo atmosfÃrica. A estimativa da massa especÃfica a altas pressÃes (atà 300 MPa) foi realizada por meio de uma equaÃÃo do tipo Tait. Para o desenvolvimento deste trabalho, foi criado um banco de dados, composto de 21845 dados experimentais de massa especÃfica para 863 diferentes lÃquidos iÃnicos puros alÃm de 994 dados experimentais para misturas binÃrias contendo compostos dessa classe. Os resultados obtidos indicam que o modelo proposto foi capaz de estimar satisfatoriamente o comportamento volumÃtrico (T, P, ρ) de uma grande variedade de lÃquidos iÃnicos puros (incluindo espÃcies policatiÃnicas), bem como o comportamento (x, T, ρ) das misturas binÃrias estudadas. Na etapa final do trabalho, o mÃtodo foi comparado com os trÃs melhores modelos de mesma natureza existentes na literatura. A anÃlise de uma sÃrie de critÃrios indicou que o mÃtodo à competitivo frente aos existentes, o que encoraja sua utilizaÃÃo e implementaÃÃo em simuladores de processos.
