In this Ph.D. thesis I am dealing with the effect of dynamic irradiance on (i) photosynthesis, growth and bundle sheath leakiness (for CO2) of C4 plants and (ii) bryophyte photosynthesis. Part of this thesis is literature review on broader aspects of the dynamic light effects on photosynthetic and growth processes in plants.

This master thesis deals with design and realization of multistage electromagnetic accelerating device (gun) and possibilities to increase its effectivity. This work contains a simulation of a magnetic circuit and designs of each components, inclusive of control circuits. Reached effectivity will be measured by appropriate methods.

In this work deals with magnetic fields for use in biomedicine. This solution involves the choice of the correct geometric arrangement of coils for generating magnetic field with a homogeneous distribution of magnetic induction of the widest possible area. The paper compares thre traditional types of coils, solenoid, toroid and Helmholtz coil. For Helmholtz and solenoid coil and is then carried out an analysis of the magnetic flux density in the inner space. Next part is devoted to electrical resonance in the LC circuit. This is then utilized for the development of pulsed magnetic field in the Helmholtz coil. It summarizes the theoretical and practical knowledge to design and construction of resonant converters. The end is devoted to the measurement of circuit parameters and verification of theoretical knowledge.

The aim of this research is to explore the influence of magnetic field on early somatic embryos (ESEs) of spruce and pine. The magnetic field is gradual. This is important for the experiment, each cluster of ESE was exposed to magnetic field of different intensity. The resulting report of this experiment consists of the comparison between various methods of image analysis and the difference in growth of ESEs due to different exposure to magnetic field and surrounding temperature. Enclosed is a proposal of ESE size computing algorithm from a given image.

This thesis deals with distribution of magnetic fields in the DC machine. Part of this thesis is the introduction of DC machines, principles of operation and distribution of DC machines. There is also discussed electrically commutated motors. The thesis demonstrates the types of permanent magnets and their properties. Then there is an analysis of the magnetic field electrically commutated motor Atas Nachod in the Ansoft Maxwell. Using Ansoft Simplorer, switching is carried out of the engine. Another part of this work is the analysisthe magnetic field electrically commutated motor Atas Nachod for three types of slot of the stator of the engine. Here it is seen what impact the change has slot on the distribution of magnetic field in the EC motor. Finally, training is carried out measurements of electrically commutated motor BOYANG BY92BL48-4000-2200.

This master´s thesis is focused on obtaining electrical energy from vibration control car using electromagnetic dampers. The primary use of the electromagnetic damper is the production of electrical energy, which can then be used to power electrical appliances in your car or battery charging. The thesis is divided into six main parts: a literature review of possible ways of getting electricity from the car damping, theoretical and mathematical analysis of problems, the choice of design with computational analysis of dampers and power calculation.

Master’s thesis is focused on marketing research. The goal of this research is to know and describe the prospects and their perception of the product. Beside this goal the thesis demonstrates possible use of general statistical induction in the field of marketing research. The object of the research are social units carrying business in agriculture, forestry, timbering and building industry.

This thesis deals with modifications to the construction of vibration-to-electricity energy converter, which is one of possible solutions to problem of sustainable and stable energy source for wireless sensor supply. Upon the exploration of the present state of this problem, new construction of generator is proposed. The aim of this proposal is to enhance the existing generator properties with respect to retention of its dimensions and its weight. Results obtained by simulations of model with proposed parameters are presented and analysed.

This thesis deals with options of laboratory heating of high voltage cables. First part of the work is reserved for description of heat as physical phenomenon and quantities connected with the heat. Second part deals with options of temperature measurements of objects in practical use and third part of the work deals with options of cables heating regarding the measurements according the ČSN rules. Practical part of diploma thesis is focused on physical phenomenon description, being under way during measurement using selected methods in individual components and optimization of results for practical measurements.

This disertation thesis thematize the relationship to the future in high school students' and the diagnostic possibilities of this phenomena. We will describe the philosophical and primarily the psychological conception of time. The thesis focuses on the main theoretical concepts of time perspective, the cognitive-motivational theories and their relationship with achievement motivation. The empirical part has three goals: 1. The diagnostic of time perspective, 2. The description of students'relationship to the future, 3. The investigation of relationship between time perspective and achievement motivation. The analysis of the coding system of the Motivational Induction Method lead to improving this system. There was a battery of tests (quantitative and mixed methodology) used to diagnose the time perspective of students', namely Motivational Induction Method (Nuttin), Zimbardo Time Perspective Inventory (Zimbardo), Achievement Motivation Questionaire (Hrabal, Pavelková) and Motivational Sources of Learning Activities (Pavelková, Hrabal). The case studies that can show positives and/or negatives of used methods and individual ways of representing the future are presented in the end of the thesis. Key words: time perspective, future time perspective, perspective orientation, achievement motivation,...
