Rodinný stav jako diferencující faktor demografického chování / Marital status as a differentiating factor in demographic behavior

Nedomová, Radka January 2014 (has links)
Diploma thesis explores the diversity of demographic behavior depending on marital status and is aimed at summarizing the effect of marital status on demographic behavior as a whole. The first phase deals with the concepts of impact of marital status on demographic behavior, explains the theory of selection and causality and outlines the historical development of nuptiality and divorce by using basic indicators. The practical part is based on the results of Population and Housing Censuses during the period 1961-2011 and compares the changes in the structure of the Czech population by sex, age and marital status between censuses. Emphasis is placed on the period after 1990. Furthermore, in separate chapters is mapped out how marital status affects demographic processes of fertility, abortion, nuptiality and mortality. In the case of fertility exploration is emphasized increasing extramarital fertility, as more and more children are born outside marriage, especially to single mothers. By using age-specific and standardized rates are analyzed changes in the development of individual demographic processes between censuses for all categories of marital status. Standardization of mortality for the years 1961, 1970 and 1980 is made on the basis of the formation of shortened life tables and the subsequent modeling of mortality at higher ages. In connection of changing structure of the population by marital status, as the proportion of unmarried and divorced people is growing and the share of people living in a marriage is decreasing, is judged attitude of the Czech public toward marriage and family according to surveys results available.

Compact Sensors for Evaluation the Thermal Comfort / Compact Sensors for Evaluation the Thermal Comfort

Kazkaz, Mohammad January 2017 (has links)
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.

Železobetonová konstrukce vysoké administrativní budovy / The concrete structure of a high office building

Skuhravý, František January 2018 (has links)
Aim of The Diploma Thesis was to design load-bearing structure of a multi-storey reinforced concrete building, to realize structural analysis in Dlubal-RFEM software and dimension its selected parts. Designed structure is based on already erected building in office edifices campus in Brno-Slatina district. Its original number of storeys was increased from ten to nineteen, so the specific problems connected to high-rise building designing could be solved. Time dependent deformations of vertical structures were analysed in detail, so the changes in load of horizontal elements could be described more precisely, because of its direct dependence on compression of the columns. Within the paper, foundation structure dimensions were designed, assessment and design of composite columns assembly were made, as well of floor slab in 2nd floor with column deformations impact check on the 17th floor. Also, the external walls, pillars and shear core walls were designed and assessed. Formwork drawing of designed structure parts and detailed drawing of reinforcement of assessed elements were elaborated. Based on Diploma Thesis results it can be stated, that if influence of nonuniform load of vertical structures within the high-rise building designing is neglected, consequent project would presumably be uneconomic, or dangerous after an optimization attempts.

Vraňanová, Veronika January 2019 (has links)
The main goal of this diploma thesis was to project a design of arch bridge‘s framework over the Svratka river. This single-span bridge has the span of 52,5m. The framework is constructed from a pair of beams, suspended from the pair of beams bent towards each other. The bridge deck is coupled with steel crosspieces. The construction design was executed in computing programme Dlubal RFEM 5.07. The individual components of the framework were assessed in Microsoft Excel. The calculation considered the load of wind and pedestrians’ movement and their effect on the dynamics of the construction. The phases of development were also considered. Assessments of coupled cross-section, main beams of steel construction, tension systems and selected construction joints were executed in a static calculation. Moreover, a design of a bearing and a bridge plug joint. Finally, a drawing documentation and a final report were prepared in regards with the requirements. The construction design and its assessment were executed according to valid standards.

Intenzivní dům v Brně / Intensive Urban Housing

Hurych, Martin January 2015 (has links)
The study deals with a proposal to deal with an area of 27 hectares in the city of Brno - Center. The premises of the former military warehouses on a plot between the streets of Veveří, Pekárenská, Kounicova and Sokolská. At present there are used by supermarket, other buildings deteriorate and are intended for demolition. At the southern corner of the parcel is located on the street Veveří tram stop. From here you can easily walk through the plot in Kounicova street, but the current state of the environment at the site of the area devalues the experience of being in such a space and aesthetics due to the surrounding historic buildings. The dominant element on the corner of the parcel is a protected sycamore. The proposed structure is suited to the current understanding of the world. Combines resources for intensive way of life with the necessary convalescence and his need for space with greenery, calm and light. The concept uses a nautical elements inserted into the context of the Czech Republic and simultaneously builds on Brno functionalism.
