Analysis of an Electromagnetic Wave on the Boundary between Electromagnetic Materials
Kadlec, Radim ; Lazar, Josef (referee) ; Macháč, Jan (referee) ; Kroutilová, Eva (advisor)
The proposed dissertation thesis contains an analysis of conditions on the boundary between layers having varied electromagnetic properties. The research is performed using consistent theoretical derivation of analytical formulas, and the underlying problem is considered also in view of multiple boundaries including the effect of the propagation of electromagnetic waves having different instantaneous speed. The author presents a survey and formulation of the basic characteristics of methods used for electromagnetic wave propagation analysis; in this respect, special emphasis is placed on radial models. The processing of the topic involved the designing and verification (using a set of different, layered planar materials) of algorithms to analyze the electromagnetic field components. The algorithm was assembled to enable simple evaluation of all components of the electromagnetic field in relation to the speed of the wave propagation in a heterogeneous environment. The proposed algorithms are compared by means of different numerical methods for the modelling of electromagnetic waves on the boundary between materials; moreover, electromagnetic field components in common points of the model were also subject to comparison. When in conjunction with tools facilitating the analysis of material response to the source of a continuous signal, the algorithms constitute a supplementary instrument for the design of a layered material. Such design enables the realization of, for example, recoilless plane, recoilless transition between different types of environment, and filters for both optical and radio frequencies.

Analysis of chosen muscles of an individual with a single sided amputation (above the knee) during a walking motion
Machač, Jan ; Fořterová, Petra (advisor) ; Süss, Vladimír (referee)
Název: Analýza aktivity vybraných svalů u člověka s jednostrannou nadkolenní amputací při chůzi An Analysis of chosen muscles of an individual with a single - sided amputation (above the knee) during a walking motion Cíl práce: Cílem práce je ověřit metodiku a způsob hodnocení elektromyografického záznamu a kinematické analýzy pro hodnocení chůze jedinců s jednostrannou nadkolenní amputací. Úkoly práce: - Shromáždit teoretické podklady týkající se problematiky amputací, elektromyografie a lokomoce amputovaných. - Zpracovat pilotní studii: Vybrat vhodného probanda pro provedení měření. Zvolit svaly, jejichž činnost budeme analyzovat. Pomocí záznamu EMG sledovat aktivitu vybraných svalů při chůzi s protézou. Pomocí záznamu EMG sledovat aktivitu vybraných svalů při chůzi bez protézy. Dle výsledku měření charakterizovat činnost sledovaných svalů, charakterizovat jejich koordinaci a intraindividuálně ji porovnat u obou typů lokomoce. Metoda: Jedná se o pilotní studii deskriptivního charakteru s využitím povrchové EMG měření v kombinaci s plošnou kinematografickou analýzou pomocí synchronizovaného videozáznamu. Tato studie je pilotní ke zpracování diplomové práce. Výsledky: Na základě uvedených tvrzení lze konstatovat že metoda EMG umožňuje sledovat změny v elektrické aktivitě vybraných svalů...

The comparison of EMG activity of selected muscles during walking and skiing - group LW2
Machač, Jan ; Fořterová, Petra (advisor) ; Kračmar, Bronislav (referee)
Title: The comparison of EMG activity of selected muscles during walking and skiing - group LW2 Aim: The aim of this study is the analysis of the activity of selected muscles of an individual with one-sided, above-knee amputation during walk with an artificial limb, after the mobilisation of the sole, and the comparison with their activity during downhill skiing. Method: This is a case study of a descriptive charakter performed through surface EMG in conjunction with simultaneous video recording. The observation of the kinesiological content of the muscle movement was done through comparative analysis, with the aid of a qualitative analysis of the video recording and a qualitative comparison of the intensity of the electric potential of the selected mescles. Results: Different character of the working of the lower limb during walking with artificial limb and during the performance of a curve on inner and outer egde with one or both stabilisers was shown. With caution, we can characterise skiing as a kinetic aktivity, predominantly of a postural charakter. Free "bipedal" walk, on the other hand, is a locomotion with a predominant character of phasal muscle activity. Key words: amputation, bipedal locomotion, downhill skiing, electromyography.

Trust and Environmental Regulations
Hlaváček, Jan ; Geuss, Erik (advisor) ; Macháč, Jan (referee)
This thesis analyzes impact of social trust on environmental regulations stringency. Negative effect is suggested. Thesis documents that, in a cross section of countries, there is no evidence of such an effect. On the other hand, there is evidence of positive impact of GDP per capita and level of education.

Economic analysis of influence of weather extremes on working and return on investment of small hydropower plants in the Czech republic betwen 2000-2015
Pavlík, Vladimír ; Macháč, Jan (advisor) ; Louda, Jiří (referee)
Nowadays, investments to small hydroelectric power stations are still highly profitable. Return on investment of a small hydroelectric power station is frequently half the period guaranteed by the state or by energy regulatory authority (Energy Regulatory Office, ERO). There is an information asymmetry among the state, as the entity that providing a subsidy, and operator of a small hydroelectric power station. These power station have constantly great potential. However, the risk of extreme hydrological fluctuations caused by floods or drought is discussed more thoroughly. Consequently, these fluctuations might harm the return on investment. The aim of this thesis is to determine to what extent hydrological extremes will affect the return on investment...

Analysis of energy saving in Czech republic with respect to EU/2012/27 regulation
Barczi, Šimon ; Vojáček, Ondřej (advisor) ; Macháč, Jan (referee)
This thesis discusses the implementation of EU Energy efficiency directive into national legislatures and the fulfilment of its goals. It expands on the past reports, correct for their mistakes and provide a new unique approach to track the current progress. The thesis analyzes all member states national action plans for energy efficiency (NAPEE) and compares them in between each other. The quality of NAPEEs is critically evaluated and described. In first section it explains and narrows the most crucial definitions. In second section it gives the basic summary of the regulation to interested readers. Followed by in depth analysis and evaluation of all EU member states national action plans for energy efficiency. The following chapter then deals with solely with Czech NAPEE. The last section provides the hard data and exclusively developed indices that tracks the progress toward EU 2020 goals.
