Abstract:
SHRNUTÍ Design Assistance System (DASY)[1] umožňuje použit přistup, kdy konstrukter/vypočtař potřebuje propojit všechny aspekty navrhu pro dosaženi optimalniho řešeni. Tento članek je zaměřen na prezentaci vybranych vypočetnich metod a jejich integrace do DASY. Metody kombinuji CAD konstrukčni navrhy současti spalovaciho motoru s modely pro vypočet dynamiky klikoveho a rozvodoveho mechanismu. Vypočetni modely jsou řešeny v komerčnim softwaru nebo přimo v DASY. Koncept pro navrhovani zdvihove křivky ventilů je představen jako zastupce metod, ktere mohou byt řešeny přimo v DASY pomoci Gauss-Newtonovy iteračni metody. Vyvinute koncepty mohou byt dale začleneny do modelu celeho motoru nebo vozidla diky blokove struktuře DASY

Abstract:
The topic of this thesis is geometry, its practical usage in architect’s profession (especially its application in computer design and realization of buildings) and its current way of teaching at schools of architecture. The thesis systematically describes geometric objects’ construction and properties, its modelling in CAD systems and examples of its usage in architecture, in some cases including the way of its realization. Geometric objects are systematically organized into chapters about point, curves, surfaces and solids. The outcome of the thesis is a concept of geometry courses modification in the way that they encourage the spatial imagination development instead of “drill” and the gained knowledge is directly useful in architect’s profession. A supplementary research (in appendix) analyses the state-of-the-art of teaching of geometry at selected schools of architecture in Europe and its effect to spatial imagination development. The research was focused at contents and form of the selected geometry courses and its influence to spatial imagination.

Abstract:
The zero coupon yield curve is one of the most fundamental tools in finance and is essential in the pricing of various fixed-income securities. Zero coupon rates are not observable in the market for a range of maturities. Therefore, an estimation methodology is required to derive the zero coupon yield curves from observable data. If we deal with approximations of empirical data to create yield curves it is necessary to choose suitable mathematical functions. We discuss the following methods: the methods based on cubic spline functions, methods employing linear combination of the Fourier or exponential basis functions and the parametric model of Nelson and Siegel. The current mathematical apparatus employed for this kind of approximation is outlined. In order to find parameters of the models we employ the least squares minimization of computed and observed prices. The theoretical background is applied to an estimation of the zero-coupon yield curves derived from the Czech coupon bond market. Application of proper smoothing functions and weights of bonds is crucial if we want to select a method which performs best according to given criteria. The best performance is obtained for Bspline models with smoothing.

Abstract:
Mixing of backfill of the pipe drain construction with sub-ballast layer material through using enclosed drainage systems (mostly by pipe drains) has to be prevented. In order to do so, regulation SŽDC S4 Železniční spodek provides a filtration criterion which needs to be fulfilled or a geotextile with filtration function has to be used. This master thesis verifies if filtration criteria are fulfilled in between different backfilling of the pipe drains and sub-ballast layers in compliance with TNŽ 73 6949. Furthermore a verification of filtration function of different geotextiles including propositions of their suitable placement within construction of the pipe drain system is included.

Abstract:
The thesis is devoted to analysing of flexible buried arch structures. Modelling of the flexible concrete arch is carried out via a nonlinear finite element model that accounts for soil constitutive relations, soil-structure interactions, sequential construction stages and soil compaction. Advanced FE-model was verified by measurement obtained by full-scale field testing of two buried arches. Mathematical optimization methods of genetic algorithms and Levenberg-Marquardt method are applied to already calibrated complex computational models in order to reduce bending and associated flexural stresses in the concrete section of buried arch. Centre line of the arch is parameterized by cubic Bezier curve to reach interpolation of thrust line. Optimization technique is applied with extensive parametrical study which shows the optimal shapes for buried arches of various span/rise ratios, backfill depths and foundation soil types. For practical application are given coordinates of Bézier curve control polygons of particular resulting shape. Subsequently is applied optimization method for a theoretical reduction of tensile stresses obtained by shape optimization of previously verified numerical model of buried arch. Comparisons of earth pressure, bending moment axial force and deflection of flexible structure during sequential construction of different span/raise ratios of buried arches are presented. The behaviour of flexible buried arch with effect of local traffic load model LM1 has been analysed via 3D finite elements model with respect to different depth of backfill above crown.

Abstract:
Presented master’s thesis describes the design and the implementation of an experimental device used for the study of tribological aspects of wheel-rail contact. In this work, the reader will first learn the fundamentals such as adhesion, slip, traction curve, etc. Subsequently, the work is describing devices that are used for the study of wheel-rail contact around the world. This section is followed by the author proposed solution. The result is a twin disc device in the scale of 1:3. The device allows determining traction characteristics for different environmental conditions (presence of water, sand and oil in contact for different temperatures) and various operating parameters (contact pressure and speed). A part of this work are also the validation experiments and complete design documentation.

Abstract:
This dissertation is concerned with the foundations in volume unstable soils and objects disorders which are related to this. The thesis was focused on the study of clay and loess soils which are abundant in the geological profile of the Czech Republic. First, the formation of the two groups of soils is introduced, then their properties are examined and finally the influence of vegetation on the former type and the influence of collapsibility in the latter type are investigated. The conclusion is, in fact, a recommendation on the design of structures so that the system of clay / structure is not damaged and that structures are not subject to renovations. Several instance of problems with structures are discussed which were subject to structural repairs employing both a civil and geotechnical engineers.

Title: Curves of constant width Author: Miroslav Němec Department: Department of Mathematics Education Supervisor: RNDr. Antonín Slavík, Ph.D., Department of Mathematics Education Abstract: The aim of this thesis is to familiarize the reader with the notion of the width of a given plane curve, and with curves having the same width in all directions. We focus our attention especially on those curves that are constructible using straightedge and compass. The chapters presenting the definition and measurement of curve width, as well as the construction of curves from circular arcs, are accessible to high-school students. We also briefly mention other related topics, such as the solids of constant width. Keywords: Width of a curve, constant width, construction, properties
