Low-cost sensors for measurement of particulate matter
Dvořáková, Michaela ; Pokorný, Jan (referee) ; Lízal, František (advisor)
This work focuses on the research and comparison of several types of low-cost sensors for measurement of particulate matter. It clarifies the principles of aerosol particles measurement and focuses on the reasons of using low-cost sensors. It provides basic information about the impact of aerosols on human health. The experimental part of this work compares quality of the obtained results considering the price of the respective devices.

Proposal of a Long-Term Financial Plan
Dvořáková, Martina ; Dvořák, Milan (referee) ; Sághy Estélyi, Kristína (advisor)
The main goal of this Diploma thesis is compiling of longterm financial plan for chosen company. This issue is dedicated theese chapters. In theoretical basis is listed theoretical part of financial planning. In analysis of issue and present financial situation is set a few chosen instruments of financial analysis, which evaluate present financial situation of company, Strategic analysis of company will focus on the current situation and the company's potential The last part is custom design solution where is processed longterm financial plan through planning of statements, which is then subjected to a check of financial analysis.

Family house
Dvořáková, Markéta ; Manová, Ludmila (referee) ; Maceková, Věra (advisor)
This bachelor's thesis deals with the design of a new family house. The content is the project documentation for construction work. The building is located in the cadastral area of Drnovice u Vyškova on a flat plot. The family house is designed for fiving of four to five persons. It is a two-storey building, the second floor of which forms the quiet zone of the house. The building is designed as a detached house with a residential attic in 2 NP. It is a brick building of the Porotherm system. It will be roofed with a saddle roof with a 30° inclination with a ceramic folded cover.

Behavior of concrete at high temperatures
Dvořáková, Michaela ; Bruckner,, Dipl Heinrich (referee) ; Bodnárová, Lenka (advisor)
The aim of this diploma thesis is to focus on the resistance of concrete exposed to high temperatures especially with focus of resistance against explosive spalling as well as clarifying the mode of action of various types of polypropylene fibres. The theoretical part is an introduction to the issues of explosive spalling, its mechanisms and majority influencing factors. Further description of the processes taking place in the structure of concrete under extreme thermal load, distribution and size of pores in concrete, thermal load, temperature-time curves and their applications, methods of elimination of negative behaviour of concrete exposed to thermal loading (passive and active methods), mode of action of polypropylene fibres and more is also included in the theoretical part. The main aim of experimental part is to verify the function of polypropylene fibers of various Melt Flow Indexes (MFI) and dosage. Primarily, the test samples with content of the PP-fibers are compared to the reference sample without fibers. Secondarily, the samples with standard PP-fibers (with MFI 25) with dosage 2.0 kg/m3 are compared to samples with modified PP-fiber (with MFI 2500) of dosage 0.9 kg/m3. Photogrammetric images were used for evaluation and comparison of spalled surfaces and its depth. Determination of the softening temperature and melting point of the modified and standard PP-fibers was made by using a high temperature microscope video. The second part of the experimental work was to define concrete permeability at different temperatures and pressures. Permeability was measured at temperatures of 20°C, 90°C, 150°C, 175°C, 200°C, 225°C and 250°C and at pressure of 0.2, 0.4 and 0.6 MPa.

Dvořáková, Martina ; Buchalová, Jana (referee) ; Chovancová, Jitka (advisor)
The aim of this bachelor’s thesis is an assessment of chosen construction company’s health from financial view using the methods of financial analysis. This thesis consists of two main parts. In the first part of this thesis is defined theoretical knowledge necessary to understanding this issue. In the second part, the financial analysis of the construction company has been made and subsequently, precautions are made to improve the financial and economic situation.
