The diploma thesis deals with analysis and modeling of power line communication using NS-3. The introduction part summarizes basic information about PLC technology, distribution grids, and broadband standards. This is followed by the analysis of the transmission line and modulation method. Furthermore, the simulation tool and possibilities of its extension are described. The influence of different cross-section and type of line on channel capacity is examined in the practical part of this paper. The influence of repeaters on bitrate is examined as well. The medium-voltage line was implemented and further scenarios dealing with bitrate or optimal level of noise. The focus of the last part is to find the repeaters on the path and to determine the capacity and bitrate on the path of the large topology.

The master's thesis is devoted to the comparison of different types of lithium-ion batteries. Primarily, an introduction to electrochemical power sources and their division is described. Furthermore, the thesis deals only with lithium-ion batteries. In the theoretical part, the chapters discuss the history, the principle of operation and a detailed description of the main battery parts, including used materials. A comparison of commercially available lithium-ion cells with each other as well as with other types of batteries is also included in the theoretical part. The practical part deals with the cyclinf of lithium-ion cells and subsequent evaluation of the effect of temperature on the capacitance and current characteristics of these lithium-ion batteries.

This diploma thesis was focused on biologically active compounds determination. 26 samples of honey, one sample of propolis and one sample of royal jelly were analyzed. Honey were harvested in year 2006 and 2007 and bought in retail chain, special shops and directly from bee-keeper. Samples were analyzed by titration, spectrofotometry, LC/MS and RP-HPLC methods. The study was focused on analysis of antioxidants. Followed groups of antioxidants were determined: flavonoids, catechins, carotenoids, vitamins E, C, A. Authenticity of quality was determined by hydroxymethylfurfural analysis. Average values of total antioxidant capacity ranged (12.75-137.49) mmol .100 g-1. Average values of total phenolic ranged (8.51-61.34) mg .100 g-1 and average values of total flavonoids ranged (0.75-6.04) mg .100 g-1. Honey samples contained (41.83-585.10) g .100 g-1 of rutin, (9.30-313.40) g .100 g-1 of myricetin, (6.5-171.90) g .100 g-1 of luteolin, (3.19-436.37) g .100 g-1 of quercetin, (2.10-242.66) g .100 g-1 of apigenin, (0.15-105.12) g .100 g-1 of caempferol and (0.07-17.52) mg .100 g-1 of naringenin. From group of catechins there were measured (5.98-310) g .100 g-1 of catechin, (17.77-486.29) g .100 g-1 of epicatechin, (0.18-64.90) g .100 g-1 of catechin gallate and (0.59-140.56) g .100 g-1 of epicatechin gallate. From lipophilic compounds the most abundant in honey samples was tocopherol, its value ranged (29.20-8531.17) g .100 g-1. Content of ascorbic acid ranged (0.65-4.65) mg .100 g-1. Content of hydroxymethyl.furfural. ranged (0.26-4.06) mg .100 g-1. By LC/MS method luteolin, naringenin, protocatechin acid, coffee acid and p-cumaric acid in honeydew were detected and, furthermore, kyanidin and pinocembrin in floral honey were found. Mono-floral honey contained biologically active compounds the most, imperceptibly less contained multi-floral honey and honeydew honey. Acacia honey contained the lowest amount of biologically active compounds.

This thesis deals with determination of content of vitamin C in various types of cornelian cherry (Cornus mas L.). Some basic information about Cornus mas L. and its various types are described in the literary part of this thesis. The summary of important components present at fruit and some possibilities of processing and utilization are described here too. Various methods of determination of vitamin C are presented at the end of the literary part. The main result of the experimental part of this thesis is the comparison of content of vitamin C in various types of cornelian cherry (Cornus mas L.). Reversed Phase-High Performance Liquid Chromatography was used as the main method. HPLC method of determination of vitamin C in various types of Cornus mas L. was completed with the orientation titration. Then total antioxidant capacity of fruit was evaluated by using of reaction of extracts of fruit with stable radical DPPH. The biggest amount of vitamin C was determined in the Fruchtal variety. The biggest total antioxidant capacity was determined in the Vydubecký variety.

Due to a signifikant development of computer networks in the last few years the demands for measurement of network metrics increased. This master´s thesis is dealing with standards for testing and test techniques used for the measurement of network metrics. Further it compares the existing free accessible measurement tools and metrics measures them. Finaly the thesis draws up a web application for measurement of the basic network metrics.

This master’s thesis is focused on evaluation of standard uncertanities of measurement by method GUM and Monte Carlo and theirs comparation. In first part of this thesis is made the theoretical analysis of evaluation of measurement uncertanities and proposal of methodology for evaluating uncertainties by Monte Carlo method. In the second part is described direct and indirect measuring of resistance, capacitance and inductance, including evaluation of standard uncertanities of those measurings by GUM and Monte Carlo methods. In the end of this thesis is made comparison of achieved results of spoken methods.

The diploma thesis contains the business plan study for increase of the production effectiveness via improvement of Overall Equipment Effectiveness.

The subject of my thesis was traffic-engineering solution to the crossroads of the streets Osvobození - Podřevnická in several options. For these options were designed needed construction adjustment next was selected one option and after taht was carried out capacity assessment of the crossroads in accordance with relevant technical regulations. To verify the capacity assessment was carried out simulations using the proposed variants Aimsun.

Design of reconstruction the damaged streambed Rusava in the village Rusava The task of this thesis is to evaluate the existing capacity of the streambed and design the reconstruction of Rusava river km 26,000 to 28,230. Rusava watercourse takes place in urban area of village Rusava in Zlín region. Channel revetment was badly damaged by floods in July 2011. The assessment of the current state of the watercourse was based on personal visit of the place and taken photos. Current state was modeled in HEC – RAS 3.1.3 software. The reconstruction is designed according to the assessment of the current river channel condition and also contains proposals for new buildings on the river.
