This diploma thesis is focused on marketing mix of a concrete company, which is operating in international environment. The thesis is divided into three main parts. The theoretical part describes basic concepts related to the topic. The analalytical part of the thesis focuses on the business environment of company Dieffenbacher CZ, assuming its future expansion to Russian market, while the results obtained are further summarized in SWOT analysis. The practical part offers proposals and recommendations from the perstective of marketing mix for successful entry of a selected engineering company to Russian market based on the findings from the complied analyses and theoretical concepts.

This Master´s thesis is focused on block of flats project documentation. The documentation is worked for building construction. Emphasis is placed on structural, space, fire safety, thermal and acoustic requirements. Masonry building is secluded and has four floors, without cellared, with a gabled roof. The building is designed with eight flats and one of these flats is designed for persons with reduced mobility.

This master thesis is divided into two parts: theoretical and practical one. In the theoretical part there is described hydraulic roughness, velocity distribution in the case of hydraulically rough surface and the process of grain sorting in surface layer. The practical part of the thesis resolves the influence of surface layer on hydraulic roughness of bed, expressed by Nikuradse sand grain size ks. The results are formulas explaining dependence of ks on characteristic grain size dx from grain-size distribution curve and comparison with coefficient ks according to different authors.

The subject of this thesis is energy storage systems in building services. In the first part the theoretical acquaintance with the nature of energy storage. In the second part has two variants preparation hot water in an apartment building. In the third part of the test solution storage tank of hot water. Development of computational algorithms, comparison of calculation used and the final summary.

This thesis describes the design work for the measurement of air values. The first part describes the airflow, pressure build-up in pipes and losses due to airflow losses. There is also a description of fans and explain their characteristics depending on the pressure generated by airflow. The next part describes the design of the measuring chamber, electronics and control for fully automatic measurement of air quantities.

The master thesis deals with thermal hydraulic design and strength design of a heat exchanger with “U” tube bundle inside of a shell. The first chapter introduces general design issues of the heat exchangers. The following chapter describes thermal hydraulic design created in software Maple 16.0 by using Kern’s method and the method of Bell-Delaware. HTRI software was used for the control of thermal hydraulic design correctness. To check critical locations of fluid flow in space between the tubes, the CFD model was created at ANSYS Fluent 14.0 software. Accuracy of strength design was verifying by Sant’ Ambrogio software in accordance with ČSN EN 13 445 standards. The last chapter concerns with FEM analysis. According to standards ČSN EN 13 445 the design by analysis namely method based on stress categories were used for the strength analysis of nozzle.

This thesis is focused on the thermal-hydraulic and construction design of heat exchanger with floating head. The introductory part is dedicated to the design of heat exchangers. Next part is focused on the thermal-hydraulic design created in HTRI software (module Xist. The next section is the strength calculation of selected components of the heat exchanger according to EN 13445 in software Sant'Ambrogio. The following part describes each of the analysis in software Ansys Workbench. The final part contains complete manufacturing documentation of heat exchanger.

This thesis deals with design of hydrostatic drive for multipurpose loader and tool carrier DAPPER. At the beginning is research of different basic concepts and modern solutions to the problem, aided by a detailed description of competitive machine in the same performance category. Extensive comparison with other producers is included in the annexes to this thesis. Furthermore, a theoretical driving characteristic and its appropriateness is examined further on the basis of two model situations. The calculations of the individual components of the hydraulic circuit precedes drive kinematics analysis of articulated machine frame, on it final conception of hydrostatic drive is chosen. Firstly hydromotors and hydogenerator are chosen on the grounds of calculations then hydraulic hoses, filters and flow divider. Next chapters are aimed to calculations of hydraulic losses and thermal calculation of hydraulic circuit. Final part deals with introduction the final characteristics of drive. The practical parts of the work are assembly drawings with main power components and hydraulic schematic of drive.

This master’s thesis deals with the assesment of directional sensivity and accuracy of current stream velocity using electromagnetic induction meters in circumstances simulating the real measurement profiles condictions. The theoretical part of the thesis describes the issue of streamflow measurement in open channels and determination of the relevant measurement uncertainties. It also includes description of the hydraulic circuit and the subject current velocity meters. The experimental part of the thesis focuses on the effect of turbulence on the value and accuracy of measured velocity and directional sensivity of electromagnetic induction meters of current velocity. The results are compared with parameters given by manufacturers, research by other authors and with the metrological characteristics of hydrometric propellers, which are commonly used for streamflow measurement in open channels.
