Návrhy asfaltových směsí s využitím vyššího obsahu R-materiálu / Design of asphalt mixtures with the use of higher amount of RAP

Pavličík, Petr January 2013 (has links)
In the introduction of the Master’s thesis describes for obtaining and processing of reclaimed asphlalt. Major point of the thesis is design of asphalt mixtures with use of higher amount of RAP for asphalt binder course. Asphalt mixtures were designed with contents of 0%, 30%, 50% and 70% of RAP. On each asphalt mixtures were compared parameters set out by functional tests – resistence to permanent deformation and resistence to water.

Modelování tlumících zařízení v interakci s konstrukcí / Modelling of damping devices in interaction with a structure

Kalina, Martin January 2013 (has links)
The aim of my master’s thesis was to create models of the damping device and observing their behavior in interaction with the structure. First was the construction separately modeled with Java application named FyDiK2D like a model with one degree of freedom. Model of construction takes form like a high, thin rod with full circular cross section. The lower part was restrained into the subsoil. The design was to verify the correct functionality of the model by comparing the analytical and numerical solutions. For capturing the precise behavior of the structure was converted to a multi-stage model. Then the pendulum damper was applied on this construction and found amplitude lies in highest point of multi-stage model. He was then replaced by tuned mass damper. By comparing these amplitudes from both dampers was found which kind of damper is efficient for multi-stage model.

Reologické vlastnosti asfaltových pojiv / Rheological properties of binders

Hotař, Petr January 2014 (has links)
The comparison of rheological properties (complex shear modulus and phase angle and dynamic viscosity) of four paving bitumens and two polymer modified bitumens is performed in this diploma thesis. Furthermore, the empirical tests (needle penetration and softening point) were determined on these binders. Effect of asphalt binders aging was modeled using RTFOT test and modified RTFOT test (3 x RTFOT).

Relaxace smykového napětí asfaltových pojiv v DSR / Shear stress relaxation of bituminous binders in DSR

Musil, Vladimír January 2015 (has links)
The thesis describes the relaxation properties of bituminous binders determined in dynamic shear rheometer (DSR). Paving bitumen, polymer modified bitumen (PMB) and crumb rubber modified bitumen (CRmB) were chosen for comparison. In order to describe the effects of ageing on asphalt binders relaxation properties, the laboratory simulation of ageing using RTFOT and 3xRTFOT method was performed. For each binder were simultaneously conducted tests of needle penetration, softening point and elastic recovery. Selected bitumens were used for the production of asphalt mixtures. The low-temperature properties tests (TSRST) were performed for these mixtures, when the results were compared to the relaxation properties of binders determined in the DSR.

Dlouhodobá analýza ultrazvukových videosekvencí s využitím metod detekce významných bodů / Long-term Analysis of Ultrasound Video Sequences Using Interest Point Detectors

Zukal, Martin January 2015 (has links)
This doctoral thesis deals with the analysis of ultrasound (US) video sequences. It specifically focuses on long-term tracking of the common carotid artery (CCA) in transversal section and measurement of its geometric parameters in a sequence of US images. The design and implementation of a system for automatic tracking of the artery is described in this thesis. The proposed system utilizes Viola-Jones detector and Hough transform to localize the artery in the image. Interest points are detected in the area of the artery wall. These points are then tracked using optical flow. The proposed system comprises a number of innovative methods which allow to perform accurate long-term measurement of parameters of CCA and store the results. A novel mathematical model describing the movement of CCA in transversal section during a cardiac cycle is defined afterwards taking the influence of breathing into consideration. A number of artificial sequences of US images based on this model have been created. These sequences were consequently used to evaluate the accuracy of the proposed system in terms of measuring the parameters of CCA. The sequences are unique because of their length which makes them suitable for evaluation of tracking accuracy even in long video sequences.

Stárnutí asfaltových pojiv / Ageing of asphalt binders

Střasáková, Monika January 2016 (has links)
The theoretical part of this thesis describes the rheology of bituminous binders, aging of asphalt binders and laboratory methods simulating short and long term aging. The following describes an empirical tests (needle penetration, softening point ring ball method) and functional tests (complex shear modulus and phase angle, dynamic viscosity), which are performed in the dynamic shear rheometer. At the end of this section, laboratory aging of bituminous binders using method RTFOT and method RTFOT + PAV is described in more detail. In the practical part of this thesis, the results of all tests performed on the binders aged using RTFOT + PAV are introduced and compared with results of properties of non-aged binders and binders aged by 3xRTFOT.

Porovnávání středoevropských jazyků: za horizont strukturních rysů a lexikálních přejímek / Comparing Central European languages: beyond structual features and loanwords

Januška, Jiří January 2017 (has links)
Disertační práce Porovnávání středoevropských jazyků: za horizont strukturních rysů a lexikálních přejímek se soustředí na zhodnocení a přehodnocení přístupu k výzkumu jazyků střední Evropy. Hlavním cílem předkládané práce je (1) podat přehled dosavadních poznatků o porovnávání středoevropských jazyků, (2) na jeho základě naznačit možné nové směřování němu přispět. Druhá kapitola práce se věnuje areálové lingvistice, jakožto disciplíně zaměřené na výzkum podobnosti a konvergence geograficky blízkých jazyků, a zejména jejímu ústřednímu pojmu . Představuje okolnosti jeho vzniku, jeho různé definice a jeho kritické (pře)hodnocení pracích současných areálových lingvistů. Třetí kapitola sumarizuje výzkum středoevropských jazyků: různé koncepce středoevropského (popř. dunajského) jazykového svazu vzájemné vlivy lexika a frazeologie těchto jazyků a popisy situací jazykového kontaktu v areálu. Tento přehled ukázal, že hlavními doménami porovnávání jazyků areálu dosud byly strukturní rysy a lexikální přejímky a kalky. Novější vývoj lingvistiky, jak je naznačeno ve čtvrté kapitole, však operuje rovněž s jazykovými jednotkami, které překlenují a relativizují -lexikon. Nabízí se tedy, aby se rovněž komparativní výzkum středoevropských jazyků soustředil na tyto jevy zahrnutelné pod pojem idiomatičnosti. Pátá kapitola...
