Measurement of dynamic characteristic of check valves
Novák, Jan ; Himr, Daniel (referee) ; Habán, Vladimír (advisor)
Master thesis presents overview of existing types of check valves, their features, uses and issue called "cracking". Experimental part of this thesis focuses on the lift and swing check valves. Results of the measurement are evaluated from non-stationary flow point of view by developing and analyzing static and dynamic characteristics. This thesis takes into account losses and dynamic effects as main viewpoints. Two methods for measuring non-stationary velocities are used. Direct method called Gibson and indirect method laser doppler anemometry. Goal of the master thesis is to increase understanding of the check valves and their applicability.

Extension and modernization of clinic in Zamberk
Novák, Jan ; Šuhajdová, Eva (referee) ; Šuhajda, Karel (advisor)
This diploma thesis deals with the design and elaboration of the project documentation for the works required for the completion and modernization of Žamberk Health Clinic. Specifically it deals with the extension of ambulatory psychiatry of its inpatient ward. The object in focus is located in the built-up part of Žamberk and it is located in the area of the Specialist Asylum Albertinum Žamberk. The building is designed as an annex with one underground and two aboveground floors with a flat roof. It is divided into three units: a dormitory psychiatric care, the dormitory gerontopsychiatric care unit and the therapeutic block. The suggestion was to keep up the requirement to minimize the interference of existing outpatient psychiatric facility and to create operationally interconnected unit between the existing object and the extension at the same time. The construction system is considered from traditional building materials. The fundamentals are made by a combination of plain concrete and lost formwork. Vertical carrier structures are made of reinforced concrete monolithic walls for the underground floor and brick walls made of ceramic blocks for both aboveground floors. Vertical partitioning structures are also walled from ceramic blocks. Horizontal carrier structures are designed as reinforced concrete monolithic continuous boards. The object is insulated with ETICS, the roof is flat and single-skinned

Development of gypsum elements as part of a complex partition system
Skoupil, Zbyněk ; Novák, Jan (referee) ; Gazdič, Dominik (advisor)
The thesis is oriented on development of gypsum elements as part of a complex partition system in continuation of high – valuable gypsum plaster development. The first part of the task is dedicated to a theoretical knowledge in the field of gypsum binders, especially is focused on their application in manufacture of gypsum partition block and study of standard requirement. Second part is focused on designing of the trial mold, pouring of the block and assessment of gained data.

Analysis of roundabout design parameters and their impact on accidents.
Novák, Jan ; Karpíšek,, Zdeněk (referee) ; Mahdalová,, Ivana (referee) ; Macur, Jiří (referee) ; Holcner, Petr (advisor)
The dissertation deals with the analysis of roundabout design elements and their impact on accidents. The analysis objective was to identify the important elements of roundabouts that have impact on accidents. In order to achieve this goal, the multifactorial statistical safety assessment method was used on the basis of a representative sample of data, by developing several safety performance functions, verifying them and interpreting the result. Several design elements, which from the point of view of the traffic accident mechanism belong to the infrastructure factor, have been identified: AADT, average diameter, entrance width, entry angle, direct passage angle, location and many others. The original sample contained about 1200 roundabouts, which were reduced to 200 based on data availability. Accident frequencies were monitored between 2009 and 2016, i.e. for eight years, resulting in total 2674 roundabouts accidents. The result is an accident prediction model, developer based on roundabout approach design elements, and map of critical roundabouts, identified based on empirical Bayes estimate of accident frequency. Following approach parameters were identified: AADT, entry angle, distance between collision points, deviation of angles between approaches, presence of apron, presence of bypass, entry type, presence of pedestrian crossing and surrounding area type.

Traffic solution in the area Kníničská - Bystrcká
Strmiska, Tomáš ; Novák, Jan (referee) ; Holcner, Petr (advisor)
The target of this diploma thesis is to create and compare variants dealing with a complicated traffic situation in Brno-Komín. Two dynamic responsive signal-controlled junctions situated in close proximity constitute the researched area. The situation is complicated by the presence of a streetcar crossing. Conducted traffic surveys represent the first part of the thesis. Data supplied by a junction's administrator are then added to the survey results. All acquired data serve as background information for designing possible solutions. Most of the work is connected with a capacity analysis which is done according to valid regulations. A microscopic simulation is implemented to examine impacts of selected concepts. The presented concepts are then evaluated financially. Finally, an optimal variant for implementation is suggested.

Parking P&R in Brno
Janyška, Miroslav ; Novák, Jan (referee) ; Holcner, Petr (advisor)
This thesis deals with organization of parking in the city of Brno focusing on park and ride facilities. It contains basic information about transport infrastructure in Brno, integrated public transport system and multimodal transportation. The practical part is a set of proposals for locations of new P&R lots, their multi–criteria analysis, followed by estimation and comparison with the solution proposed by local authorities. The thesis also contains of analysis of a parking lot in the town of Blansko nearby Brno, that is spontaneously used as a park and ride facility.

Preparation of high performance sulphate binder by nonpressure method
Urban, Karel ; Novák, Jan (referee) ; Dvořák, Karel (advisor)
Institut of Technology building materials and components in FAST VUT Brno is for several years engageding by research of unpressurized production of high sulphate binders and also by developing a dehydrating apparatus. This work follows on this research. The main aim of this work is to prepare the alpha calcium sulfate hemihydrate by method of dehydration in the various solutions the chloride salts of the same molal concentration in an innovative dehydration apparatus. Another aim is monitoring the influence dehydrating solutions on the basis of KCl, NaCl and CaCl2 on the properities of made gypsum.
