The results showed that the most significant variations happened in the minimum temperatures,which increased expressively in Extreme North,Northwest and Southeast of the State,possibly associate to the adding of steam of water in the atmosphere.The waves of cold of the minimum temperature increased in most of the State,while,the one of the maximum temperature reduced,except in the winter. Already the heat waves of the minimum and maximum temperatures increased significantly in Extreme North and Extreme East.Groupings of the values of the test t showed two groups with positive and significant variations formed by Iraí and Pelotas, and the other by Encruzilhada do Sul and Torres. Bom Jesus was only in the group with a range of significant reduction. The other meteorological station were classified as a group significant. / Frente às possíveis mudanças climáticas globais já observadas,este trabalho objetivou identificar as tendências temporais de índices climáticos derivados das temperaturas mínimas e máximas para o Rio Grande do Sul. Foram utilizados dados diários de temperaturas mínimas e máximas de 13 estações meteorológicas entre 1961 e 2005. Estes dados foram organizados de forma sazonal e posteriormente determinaram se os índices climáticos. Os índices foram definidos pelas médias sazonais,mínimos absolutos,máximos absolutos,quatro classes percentílicas (10%, 35%,65%e 90%),ondas de frio e de calor,para as temperaturas máximas e mínimas. Foram avaliadas individualmente as significâncias (teste t) dos coeficientes de correlação dos índices das temperaturas no tempo.or fim,os valores de t foram agrupados em regiões homogêneas segundo sua significância.ara gerar o agrupamento foi aplicada a técnica K means usando como critérios de agrupamento a distância quadrática.Os resultados mostraram que as variações mais significativas ocorreram nas temperaturas mínimas,as quais aumentaram expressivamente no Extremo Norte,Noroeste e Sudeste do Estado,possivelmente associado ao adicionamento de vapor d água na atmosfera.As ondas de frio da temperatura mínima aumentaram na maior parte do Estado,enquanto que,as da temperatura máxima reduziram,exceto no inverno.Já as ondas de calor das temperaturas mínimas e máximas aumentaram significativamente no Extremo Norte e Extremo Leste.Os agrupamentos dos valores do teste t mostraram dois grupos com variações positivas e significativas formados por Iraí e Pelotas e o outro por Encruzilhada do Sul e Torres.Bom Jesus foi única no grupo com variações de redução significativa.As demais estações meteorológicas foram classificadas em grupo não significativo.

This study contributes to the current literature on time, gender, migration, culture and identity by bringing insights into how time is perceived and experienced by Syrian women who are settled and working in the UK. It is a topic that is little known in the extant literature, and that differs in its dynamics form the western literature. The notion of time has been widely debated but with little reference to its impact on the perceptions and individual experiences of migrant women, who engage with culturally different time structures and different time schedules. The spatial experiences of those women represented by their mobility across cultural boundaries seem to be affecting how migrant women perceive and organise time. Throughout the study, the Heideggerian interpretive phenomenological perspective has been adopted to make sense of and interpret the meanings and experiences provided by the participants of this study. This has been selected to allow space for considering and acknowledging the impact of the personal experience and prior knowledge of both the researcher and the researched subjects. Perceptions of time and time experiences have been found to be much diversified across personal, social and cultural contexts which are marked by spatial or geographical boundaries. Also, time structures and time schedules have been institutionally gendered across the cultures of both countries: Syria and the UK, but with varying degrees. Empirically, this study can help work organisations and agencies interested in working with migrant people to understand the diversity of perceptions and experiences of migrant female workers in the UK to enable them offering the care and services tailored to the needs of those migrants. In doing so, this research is hoped to improve the quality of work and social contributions of migrant women in the UK. Methodologically, this phenomenological inquiry contributes to the field of empirical and socio-political knowledge as well as the understanding of moral, aesthetic, and personal welfare debated in the migration literature. It contributes to the understanding of human experiences in relation to the notion of time, in isolation of any concern to predicting or prescribing any theory.

Magister Scientiae - MSc / In many forensic cases, such as mass disasters reconstruction cases, the recovered DNA is highly degraded. In such incidences, typing of STR loci has become one of the most powerful tools for retrieving information from the degraded DNA. However, as DNA degradation proceeds, three phenomena occur consecutively: loci imbalance, allele dropout and no amplification. To solve the problem of degraded DNA, redesigned primer sets have been developed in which the primers were positioned as close as possible to the STR repeat region. These reduced primer sets were called Miniplexes. Unfortunately, a few of the CODIS STR loci cannot be made into smaller amplicons. For this reason non-CODIS miniSTRs have been developed. The present study was undertaken for the population genetic analysis of microsatellite variation in four South African populations; Afrikaner, Xhosa, Mixed Ancestry and Asian Indian using eight non-CODIS miniSTR loci. These miniSTRs loci were characterized within the populations by estimating the levels of diversity of the markers, estimating the population genetic parameters, and studying the inter-population relationships. All of the miniSTRs were amplified successfully and the genetic variability parameters across all loci in Afrikaner, Mixed Ancestry, Asian Indian and Xhosa were estimated to be in the range of 3 (D4S2364) to 12 (D9S2157) alleles, the total number of alleles over all loci ranged from 100 to 204, the allelic richness ranged from 3.612 to 10.307 and the heterozygosity ranged from 0.4360 to 0.8073. Genetic distance was least between Afrikaner and Asian Indian and highest between Xhosa and Mixed Ancestry. Deviations from Hardy-Weinberg equilibrium were not observed for most of the loci. The low mean FIS (-0.027) and FIT (-0.010) and FST (0.017) values across the populations indicated low level of inbreeding within (FIS) and among (FST) the populations. The Asian Indian population showed higher levels of the inbreeding coefficient, indicating less gene exchange between it and other populations. These 8 markers can be used for genetic investigations and assessing population structure. The study contributed to the knowledge and genetic characterization of four South African populations. In addition, these MiniSTRs prove to be useful in cases where more genetic information is needed. / South Africa

The goal of this master's thesis is to provide the management of the selected undertaking with a view of possible weaknesses of their management, which may lead to problems in the future, threats present on the market having a negative external impact on the undertaking and to show the management opportunities arising from the external environment as well as strengths of their management. These recommendations will be formulated in the form of action plan. To achieve the goal of the master's thesis means to prepare the financial analysis, i.e. the internal analysis of the undertaking concerned that will serve as a source material on the basis of which strengths and weaknesses pertaining to the SWOT analysis will be formulated. To be able to prepare a competent SWOT analysis, I will perform two selected external analyses of the environment concerned, which are the PEST analysis and the Porter's Five Forces Model. These two external analyses will provide a framework depicting external factors such as opportunities and threats arising from the market. They will make it possible to compile a full-valued SWOT matrix. Based on this performed SWOT analysis, I will prepare the action plan formulating recommendations for the management of the undertaking focused on the elimination of the weaknesses of the undertaking as well as of the threats arising from the market, or possibly on the use of the opportunities present on the market and consolidation of the undertaking's strengths.

Ce travail de thèse poursuit une perspective double dans l'usage conjoint des méthodes de Monte Carlo séquentielles (MMS) et de l'algorithme Espérance-Maximisation (EM) dans le cadre des modèles de Markov cachés présentant une structure de dépendance markovienne d'ordre supérieur à 1 au niveau de la composante inobservée. Tout d'abord, nous commençons par un exposé succinct de l'assise théorique des deux concepts statistiques à Travers les chapitres 1 et 2 qui leurs sont consacrés. Dans un second temps, nous nous intéressons à la mise en pratique simultanée des deux concepts au chapitre 3 et ce dans le cadre usuel ou la structure de dépendance est d'ordre 1, l'apport des méthodes MMS dans ce travail réside dans leur capacité à approximer efficacement des fonctionnelles conditionnelles bornées, notamment des quantités de filtrage et de lissage dans un cadre non linéaire et non gaussien. Quant à l'algorithme EM, il est motivé par la présence à la fois de variables observables, et inobservables (ou partiellement observées) dans les modèles de Markov Cachés et singulièrement les modèles de volatilité stochastique étudié. Après avoir présenté aussi bien l'algorithme EM que les méthodes MCS ainsi que quelques une de leurs propriétés dans les chapitres 1 et 2 respectivement, nous illustrons ces deux outils statistiques au travers de la calibration d'un modèle de volatilité stochastique. Cette application est effectuée pour des taux change ainsi que pour quelques indices boursiers au chapitre 3. Nous concluons ce chapitre sur un léger écart du modèle de volatilité stochastique canonique utilisé ainsi que des simulations de Monte Carlo portant sur le modèle résultant. Enfin, nous nous efforçons dans les chapitres 4 et 5 à fournir les assises théoriques et pratiques de l'extension des méthodes Monte Carlo séquentielles notamment le filtrage et le lissage particulaire lorsque la structure markovienne est plus prononcée. En guise d’illustration, nous donnons l'exemple d'un modèle de volatilité stochastique dégénéré dont une approximation présente une telle propriété de dépendance. / This thesis pursues a double perspective in the joint use of sequential Monte Carlo methods (SMC) and the Expectation-Maximization algorithm (EM) under hidden Mar­kov models having a Markov dependence structure of order grater than one in the unobserved component signal. Firstly, we begin with a brief description of the theo­retical basis of both statistical concepts through Chapters 1 and 2 that are devoted. In a second hand, we focus on the simultaneous implementation of both concepts in Chapter 3 in the usual setting where the dependence structure is of order 1. The contribution of SMC methods in this work lies in their ability to effectively approximate any bounded conditional functional in particular, those of filtering and smoothing quantities in a non-linear and non-Gaussian settings. The EM algorithm is itself motivated by the presence of both observable and unobservable ( or partially observed) variables in Hidden Markov Models and particularly the stochastic volatility models in study. Having presented the EM algorithm as well as the SMC methods and some of their properties in Chapters 1 and 2 respectively, we illustrate these two statistical tools through the calibration of a stochastic volatility model. This application is clone for exchange rates and for some stock indexes in Chapter 3. We conclude this chapter on a slight departure from canonical stochastic volatility model as well Monte Carlo simulations on the resulting model. Finally, we strive in Chapters 4 and 5 to provide the theoretical and practical foundation of sequential Monte Carlo methods extension including particle filtering and smoothing when the Markov structure is more pronounced. As an illustration, we give the example of a degenerate stochastic volatility model whose approximation has such a dependence property.

Teplota vzduchu je nejčastěji používaná k posouzení tepelného stavu vnitřního prostředí. Avšak teplota vzduchu sama o sobě, je v mnoha případech pro toto posouzení nedostatečná. Hlavním cílem disertační práce je vyhodnotit tepelný stav vnitřního prostředí a specifikovat parametry, které na něj mají vliv. Teplota vzduchu, střední radiantní teplota, rychlost vzduchu a vlhkost vzduchu jsou čtyři základní parametry, které určují tepelný stav vnitřního prostředí. Vzhledem k tomu, že tepelný stav prostředí závisí na mnoha aspektech, byly odvozeny veličiny, které zahrnují kombinovaný účinek několika nebo všech těchto parametrů k určení tepelného stavu prostředí. Jedná se např. o efektivní teplotu, teplotu kulového teploměru, operativní teplotu, ekvivalentní teplotu, PMV a PPD indexy... aj. V dnešní době existuje spousta vysoce přesných senzorů, které mohou zhodnotit tepelný stav vnitřního prostředí. Z důvodu jejich vysoké ceny jsou používané převážně pro účely výzkumu. Předkládaná práce se převážně soustředí na vývoj kompaktního deskového senzoru pro vyhodnocení tepelného stavu vnitřního prostředí. Zaměřuje se hlavně na nízkou cenu senzoru společně s dostatečnou přesností. K dosažení cíle této práce jsou provedeny následující postupy: • Analýza environmentálních faktorů ovlivňujících tepelný stav prostředí. • Studium dopadu teploty vzduchu, střední radiantní teploty a rychlosti proudění vzduchu na tepelné indexy: teplotu kulového teploměru a operativní teplotu. • Teoretické porovnání teploty kulového teploměru a operativní teploty. • Navržení, rozvoj a konstrukce nového deskového senzoru pro posouzení tepelného stavu vnitřního prostředí. • Navržení a konstrukce testovací komory pro porovnávání senzorů tepelného stavu prostředí. • Kalibrace zkonstruovaného senzoru měřením fyzikálních veličin charakterizujících tepelný stav prostředí. • Testy směrové závislosti vyvinutého deskového senzoru a porovnání s kulovým teploměrem v testovací komoře. • Srovnání teoretických řešení s provedenými měřeními v testovací komoře. Výsledkem této práce je vlastní teoretické srovnání teploty kulového teploměru a operativní teploty ve vybraném rozsahu teploty vzduchu, střední radiantní teploty a rychlosti vzduchu pro možnost hodnocení tepelného stavu vnitřního prostředí pomocí kulového teploměru. Hlavním výstupem je však navržení a zhotovení jednoduchého deskového senzoru, který by byl dostatečně přesný pro měření tepelného stavu prostředí. V rámci disertace byla postavena také testovací komora a bylo provedeno testování vyvinutého senzoru pomocí měřicího systému INNOVA.
