Let f : \'K POT. \' be a \'C POT. 2\' semi-algebraic mapping for K = R and a polynomial mapping for K = C. It is well-known that f is a locally trivial topological fibration over the complement of the bifurcation set B(f), also called atypical set. In this work, we consider the notion of t-regularity and \'ho E\'-regularity to study the bifurcation set of semi-algebraic mappings f : \'R POT. n\' \'ARROW\' \'R POT. p\' and polynomial mappings f : \'C POT. n\' \'ARROW\' \'C POT. p\'. We show that t-regularity is equivalent to regularity conditions at infinity which have been used by Rabier (1997), Gaffney (1999), Kurdyka, Orro and Simon (2000) and Jelonek (2003) in order to control the asymptotic behaviour of mappings. In addition, we prove that t-regularity implies \'ho E\'-regularity. The \'ho E\'-regularity enables one to define the set of asymptotic non \'ho E\'-regular values S(f) \'This contained\' \' K POT. p\', and the set \'A IND. \'ho E\'\' := f(Singf) U S(f). For \'C POT. 2\' semi-algebraic mappings f : \'R POT. n\' ARROW \' \'R POT. p\' and polynomial mappings f : \'C POT. n\' \'ARROW\' \'C POT. p\', based on a partial Thom stratification at infinity, we rove that S(f) and \'A IND. ho E\' are closed real semi-algebraic sets of dimension at most p - 1 (real dimension at most 2p - 2, for f : \'C POT. n\' \'ARROW\' \'C POT. p\'). Moreover, based on a new fibration theorem at infinity, i.e. holding in the complement of a sufficiently large ball, we obtain B(f) \'this contained\' \'A IND. ho E\'. We study two special classes of polynomial mappings f : \'R POT. n\' \"ARROW\' \'R POT. p\', the class of fair polynomial mappings and the class of Newton non-degenerate polynomial mappings. For fair polynomial mappings, we give an interpretation of t-regularity in terms of integral closure of modules, which is a real counterpart of Gaffney\'s result (1999). For non-degenerate polynomial mappings, we obtain an approximation for B(f) through a set which depends on the Newton polyhedron of f (results like this have been obtained by Némethi and Zaharia (1990) for polynomial functions f : \'C POT. n\' \'ARROW\' C and recently for mixed polynomial functions by Chen and Tibar (2012)). To finish, we discuss some simple consequences of our work: the equivalence t regularity Rabier (equivalently Gaffney, Kuo-KOS, Jelonek) condition for mappings f : X \'ARROW\' \'K POT. p\', where X \'this contained\' \'K POT. n\' is a smooth ane variety; the problem of bijectivity of semi-algebraic mappings; and a formula to compute the Euler characteristic of regular fibres of polynomial mappings f : \'R POT. n\' \'AROOW\' \'R POT. n-1\'. The above results are also extensions of some results obtained, for polynomial functions f : \'K POT. n\' \'ARROW K, by Némethi and Zaharia (1990), Siersma and Tibar (1995), Paunescu and Zaharia (1997), Parusinski (1995) and Tibar (1998). Title: Regularity at infinity and global fibrations of real algebraic maps / Considere f : \'K POT. n\' \"SETA\' \'K POT. p\' uma aplicação semi-algébrica de classe \'C POT. 2\' para K = R e uma aplicação polinomial para K = C. Por resultados clássicos, sabe-se que f é uma fibração topologicamente trivial sobre o complementar dos valores de bifurcação B(f), também chamado de valores atípicos. Neste trabalho, consideramos a t-regularidade e a \'ho E\'-regularidade no estudo dos valores de bifurcação de aplicações semi-algébricas f : \'R POT. n\' \'SETA\' \'R POT. p\' de classe \'C POT. 2\' e aplicações polinomiais f : \'C POT. n\' \'SETA\' \'C POT. p\'. Mostramos que t-regularidade é equivalente às condições de regularidade no infinito usadas por Rabier (1997), Gaffney (1999), Kurdyka, Orro e Simon (2000) e Jelonek (2003) no controle do comportamento assintótico de aplicações. Também mostramos que t-regularidade implica \'ho E\'-regularidade. Através da \'ho E\'-regularidade, definimos o conjunto dos valores assintóticos não \'ho E\'- regulares S(f) \'K POT. p\', e o conjunto \'A IND. ho E\' : = f(Singf) U S(f). Para aplicações semialgébricas f : \'R POT. n\' \'SETA\' \'R POT. p\' de classe \'C POT. 2\' e aplicações polinomiais f : \'C POT. \' \'SETA\' \'C POT. p\', baseados na existência de uma estraticação parcial de Thom no infinito, provamos que S(f) e \'A IND. ho E\' são conjuntos semi-algébricos reais de dimensão no máximo p - 1 (dimensão real no máximo 2p 2, para f : \'C POT. \' \'SETA\' \' C POT. p\'). Além disso, baseados em um novo teorema de fibração no infinito, ou seja na existência de fibração no complementar de uma bola de raio suficientemente grande, obtemos que o conjunto de bifurcação B(f) está contido no conjunto \'A IND. ho E\'. Estudamos também duas classes de aplicações polinomiais f : \'R POT. n\' \'SETA\' \'R POT. p\', a classe de aplicações polinomiais fair e a classe de aplicações Newton não degeneradas. Para aplicações polinomiais fair, obtemos uma interpretação da t-regularidade em termos da teoria de fecho integral de módulos, estendendo para o caso real os resultados de Gaffney (1999). Para aplicações não degeneradas, obtemos uma aproximação de B(f) através de um conjunto que depende do poliedro de Newton de f (resultados deste tipo foram obtidos por Némethi e Zaharia (1990) para funções polinomiais f : \'C POT. \' \'SETA\' C e recentemente para funções polinomiais mistas por Chen e Tibar (2012)). No final, discutimos algumas consequências simples do nosso trabalho: a equivalência t-regularidade condição de Rabier (equivalentemente Gaffney, Kuo-KOS, Jelonek) para aplicações f : X \'SETA\' \'K POT. p\', onde X \'está contido\' \'K POT. n\' é uma variedade suave afim; o problema de bijetividade de aplicações semi-algébricas; e uma fórmula para o cálculo da característica de Euler de fibras regulares de aplicações polinomiais f : \'R POT. n\' \'SETA\' \'R POT. n-1\'. Os resultados acima também são extensões de alguns resultados obtidos para funções polinomiais f : \'K POT. n\' \'SETA\' K, por Némethi e Zaharia (1990), Siersma e Tibar (1995), Paunescu e Zaharia (1997), Parusinski (1995) e Tibar (1998).

<p>In this thesis we study several inverse sampling procedures to test for homogeneity in a multivariate hypergeometric distribution. The procedures are finite population analogues of the procedures introduced in Panchapakesan et al. (1998) for the multinomial distribution. In order to develop some exact calculations for critical values not considered in Panchapakesan et al. we introduce some terminologies for target probabilities, transfer probabilities, potential target points, right intersection, and left union. Under the null and the alternative hypotheses, we give theorems to calculate the target and transfer probabilities, we then use these results to develop exact calculations for the critical values and powers of one of the procedures. We also propose a new approximate calculation. In order to speed up some of the calculations, we propose several fast algorithms for multiple summation.</p> <p>N >= 1680000, all the results are the same as those in the multinomial distribution.</p> <p>The computing results showed that the simulations agree closely with the exact results. For small population sizes the critical values and powers of the procedures are different from the corresponding multinomial procedures, but when</p> / Master of Science (MSc)

This thesis aims to explain the basic characteristics of valuation method in practice use. The first chapter is about basic character of each method of valuation and factors which influence its applicability. The second chapter mentions estimation of market value/appraisal, includes affecting factors. Then, the third and fourth parts aim to comparing these appraisals (market. vs. price bargaining, subjective and objective, complex appraisal) and price formation for price bargaining in the Czech a EU market. Chain of model facets in appraisal is demonstrated by fair example in the fifth part. Mainly prefeasibility appraisal and bargaining based on the categories of value are followed. These entire complexes comparing of advantages and disadvantages of each category of value with a focus on valuation methods, in particular the consequences of their use are gone to conclusion of my thesis. At the very end of the thesis there are the main points of practical differences and their benefits to it and their contributions summarized.
