University Residential Centre

Tato diplomová práce se zabývá řešením třípodlažního objektu pro potřeby univerzity. Objekt slouží pro ubytovací a komerční účely, v přízemí se nachází menza s kuchyní, kavárna, obchody a fitness. První a druhé podlaží je řešeno jako ubytovací zařízení pro studenty s různými typy dispozic pokojů. Nosný systém budovy je železobetonový monolitický skelet, jako výplňový materiál je použito akustické zdivo. Navržená střecha je plochá vegetační s extenzivní zelení. Objekt je založen na pilotách.This diploma thesis is aimed on solution of a three-storey object for residential and commercial purposes of a university. In the ground floor there is canteen with canteen kitchen, café, shops and fitness. The first and second floors are designed as an accommodation for students with different types of room layouts. Reinforced concrete skeleton was chosen as a load-bearing system of the building and acoustic masonry is used as an infill material. The roof is designed as a green flat roof with extensive type of flora. The object is founded on piles.

Impact of IPPC Scenarios on indoor environment quality of historic buildings

Ensuring proper indoor environment quality in buildings with historic value or buildings located in historic centres of cities is not an easy task. These buildings are frequently listed in historic preservation lists; thus, the amount of possible refurbishment methods is significantly limited due to increased protection. This article deals with comprehensive analysis of internal microclimate of a multi-purpose building located in the historic centre of Prague during summer period. Possible refurbishment methods permitted by the National Heritage Institute are analysed and compared using building energy performance simulation tool BSim in order to achieve proper working conditions in offices in the building. Structural and technical modifications are proposed in order to optimize the amount of solar heat gains leading to reduction of overheating and increase of energy efficiency

Taylor's theorem for matrix functions with applications to condition number estimation

We derive an explicit formula for the remainder term of a Taylor polynomial of a matrix function. This formula generalizes a known result for the remainder of the Taylor polynomial for an analytic function of a complex scalar. We investigate some consequences of this result, which culminate in new upper bounds for the level-1 and level-2 condition numbers of a matrix function in terms of the pseudospectrum of the matrix. Numerical experiments show that, although the bounds can be pessimistic, they can be computed much faster than the standard methods. This makes the upper bounds ideal for a quick estimation of the condition number whilst a more accurate (and expensive) method can be used if further accuracy is required. They are also easily applicable to more complicated matrix functions for which no specialized condition number estimators are currently available
