The principal objective of this thesis is the comprehension of students' mental processes while solving verbal math problems about money. There searchis focused on pupils in the first stage of primary school and in particular verbal math problems, in which nominal value of coins, quantity of coins and their total particular verbal math problems, in which nominal value of coins, quantity of coins and their total sum play a key role. There fore, the objective of this diploma thesis is to lay out classify mony-related exprecises in thee currently used lies of elementary school mathematics text books for grade. The theoretical part consist of demarcation of early school age, a certain number of fanticipate dacts by RVP ZV for the first and second educational period, numeracy, literacy, verbal math problems, various strategies on how to solve such problems, basic is sues pipils encounter whilw solving those problems, coments on the topic of verbal math problems which appear in theree volume soft text books in tended for primary schools (Prodos, Taktic, H-mat). Their division into three types (a total sum of coins, nominal value of coins and number of coins) and their mutual comparision. The goal of the practial part is to analyse thought processes of and grade pupils when solving word problems about...

This work is focussed on hydraulic descaling of hot surfaces. Hydraulic descaling is a process when layers of oxides are removed from hot steel surfaces during continuous rolling. High pressure water beam is used. Quality of descaled surfaces is important for final quality of rolled product. Insufficient descaling causes drop of final quality, degradation of rolls and lost of yields. High-pressure water beam has two effects on a scale layer. The first effect is mechanical caused by impact pressure. The second one is a relatively intensive thermal shock depending on a set of parameters (water pressure, nozzle type, distance from the surface, inclination angle, speed of product moving). There are a lot of theories about principles of scales removing. Main task of this work is to make it clear which theory is acceptable and which is just ,,theory”. For this purpose mathematical modelling and experimental work were used. In experimental part, three types of experimental measurement were done. First one, measurement of dynamical effect of water beam – impact pressure. Second one, measurement of temperature drop when a product is passing under the nozzle. Measured data (temperatures) from this measurement are evaluated with inverse task and heat transfer coefficient is obtained. And the third experimental measurement is simulation of whole process of descaling. Quality of descaled surfaces is valuated according to amount of remained oxide scales. Data from firs and second experimental measurement are used as boundary conditions for mathematical modelling. For mathematical simulations, FEM (finite element method) system ANSYS was used. Obtained data from experimental measurement were applied on 2D and 3D models of basic steel material with layer of scale. Influence of theses data on final temperature, stress and strain fields were observed.

The theme of my thesis was Human resource management in the selected organization. I chose the CSOB. In the theoretical part, I wrote about the important definitions associated with this topic. For example, human resource management, human resources, intellectual capital, human capital, knowledge organization, knowledge worker, culture, corporate culture, training and staff employees, the role of the HRM manager. The main objective was to evaluate human resource management with a focus on developing intellectual capital in a particular organization. Partial objectives was: characteristics of the selected company, its historical development, targeting and mapping of the human resources department, design and evaluation of the marketing research staff focused on the functionality of human resources in the organization, analysis of data and information, and an overall assessment of current approaches to managing human resources and intellectual capital to work with the selected organization and assessment of current situation and possibilities for improvement and formulation of its own proposals and measures in the field of human resources. The practical part of my work I have a stock of internal materials the HRM system in CSOB, I conducted market research among employees. Next, I evaluated the results of marketing research and presented in the form of tables and graphs. The data analysis revealed that employees are most satisfied with the HRM system, I see only a lack of communication and access management company. Solution is open communication and improved access to management start.

The thesis deals with qualitative properties of solutions of singular initial value problems for ordinary differential and integrodifferential equations which occur in the theory of linear and nonlinear electrical circuits and the theory of therminionic currents. The research is concentrated especially on questions of existence and uniqueness of solutions, asymptotic estimates of solutions and modications of Adomian decomposition method for singular initial problems. Solution algoritms are derived for scalar differential equations of Lane-Emden type using Taylor series and modication of the Adomian decomposition method. For certain classes of nonlinear of integrodifferential equations asymptotic expansions of solutions are constructed in a neighbourhood of a singular point. By means of the combination of Wazewski's topological method and Schauder xed-point theorem there are proved asymptotic estimates of solutions in a region which is homeomorphic to a cone having vertex coinciding with the initial point. Using Banach xed-point theorem the uniqueness of a solution of the singular initial value problem is proved for systems of integrodifferential equations of Volterra and Fredholm type including implicit systems. Moreover, conditions of continuous dependence of a solution on a parameter are determined. Obtained results are presented in illustrative examples.

This Master`s thesis is focused on through acquaintance of principles of the function circuits with switched capaticors and posibility of their application mainly in frequency filters or signal generators. The origin of the switched capacitor circuits is mentioned at the beginning of the work. There are references to the first scientific work and scientists who have dealt with this issue. Maxwell`s idea: lossy element (resistor) replace with lossless element (switched capacitor) in electric circuit, is further described. In the next chapter of this work are listed types of switching capacitors and their use in simple RC filters and in structures of inverted or noninverted integrators and their application in more complex higher order filters. The advantages and disadvantages of SC circuits versus circuit composed of discrete components are shown. It is also listed a simple low-pass switched RC filter implemented with analogue multiplexer 4053. Using the LTC1043 integrated circuit, which structure and properties are described and analyzed in detail in the work, the 1st order aktive or pasive low and high pass filters were designed and subsequently simulated in the computer simulator OrCAD PSpice v.10. Another chapter deals with the integrated circuits higher order filters, structure and properties of the integrated filter LTC1060 are further analyzed here. Except this IC there are mentioned integrated filters commercially less available from the corporations Linear Technology and Maxim. The main objective of thesis was to propose and establish laboratory device and laboratory measurment focused on the switched capacitor circuits. The laboratory device has been designed with integrated circuits LTC1043 and LTC1060, which is demonstrated by using passive and active integrator, 2nd order band-pass and 4th order band-pass with Chebyshevovou approximation.
