Diploma thesis focuses on the issue of proactive risk management in companies, using appropriate procedures and methods in the selected company. Thesis is divided into three parts. First part is focused on theoretical knowledge, which serves as a basis for the analytical part. The analytical part characterizes the selected company, organizational structure, job positions and key processes in the company, with a focus on proactive risk management. In the last part of the diploma thesis, measures for proactive risk detection are suggested.

This master´s thesis deals with the differential filters working in the current mode. It is dealt with the design methodologies of these filters and conversion circuits from voltage to current mode. Own work deals with 4 types of differential participation of structures. In this work there has been used programs SNAP and OrCAD. These programs were used for simulations of filters to proposed proper design. Results from this thesis is showed by graphs.

This master’s thesis aims to analyze the possibilities of failure of human reliability on the example of an induction heater from company Roboterm spol. s.r.o. in Chotěboř. The objective of a thesis is a review of a literature of human reliability assessment. Based on the analysis of the operation and a literature review and choose the appropriate method to perform the actual assessment of the reliability of human error. Final object of the work is to propose measures to increase human reliability.

The present thesis focuses on the issue of assessing the reliability of the operator while operating CNC laser Adige LaserTube 8. The objective of this study was to perform a review of literature, which concerns the issue of assessing the reliability of the human factor. On the basis of the analysis was to choose the appropriate method in order to identify and assess risks in their workplace and then to assess the reliability of the operator. The practical part is to propose suitable measures to increase the reliability of the operator.

This thesis deals with analysis of measurement system capability in the production of rotary components from the viewpoint of operator error reduction and reliability of human factors. The aim is to carry out a literature review on the topic and then to analyze the current system in the company ZNOJEMSKÉ STROJÍRNY, s.r.o. Based on the obtained data suggest appropriate corrective arrangements to improve the current situation.

This work focuses on the issue of acoustic diffusers. The introductory chapter describes the necessary theory of the sound distribution through enclosed space. Acoustic fields are also described. A description of the different diffusion element types and theirs design methods follows. It focuses mainly on design, which uses pseudo-random mathematical sequences. The aim of the work is to produce several types of acoustic diffusors and to verify their diffusion properties by means of measurements. The work uses the AFMG Reflex to simulate the diffusion properties of the proposed elements. Further, the thesis contains a description of the diffusion properties measurement process by the boundary plane method and the process of evaluating the measured data using the Matlab program.

This thesis deals with the design and realization of wireless power charging circuit for embedded systems. The research section focuses on the various ways and technologies used in applications of wireless power transfer. The theoretical part also briefly characterizes resonant inductive coupling and critical parameters of the transfer. This is followed by realization of various variants of transfer coils and electromagnetic oscillators. Wireless power charging prototype system is created and used for testing purposes to find optimal configuration of resonator. The hardware unit presented in the final part of the thesis exploits microcontroller and implemented software is extended by foreign object detection algorithm along with method to monitor battery charging state.

My dissertation deals with the issue of quitting smoking and keeping permanent abstinence in relation to the most significant motivation factors. My particular objective was to specify the most important motivation factors as well as to confirm what effect the price of cigarettes has on giving up smoking with the 25-50 year old generation of South Bohemian geographic classification. A quantitative research was carried out via an internet questionnaire. It contained 14 questions concerning identification, treatment, motivation and finances. 63 respondents filled in the questionnaire.

The presented doctoral thesis is focused on assessment of human factor impact on safety of industrial furnaces. Industrial furnaces are classified as machinery and belong to a group of industrial thermal equipment. The operation of industrial furnaces is burdened with the risks which the manufacturers and the furnace operators realize. The first part of the thesis presents an analysis of the current situation of legislation and scientific knowledges in the field of assessment of human factor impact on safety of industrial furnaces. In this part of the thesis the issue of human factor in other industrial branches: chemical industry, aviation and nuclear industry is also described. On the basis of conducted research the main aim of the thesis was established: preparation of a methodology for assessment of human factor impact on safety of industrial furnaces. Secondary targets were also listed. The second part deals with the assessment of risks connected with the operation of industrial furnaces and the assessment of human factor impact on safety of industrial furnaces. The furnace safety requirements, the process of furnaces risk assessment, the methods used for risk assessment and problems connected with the risk assessment are described. This part of the thesis explains the concept of human factor, presents a classification and description of the methods used for human reliability assessment, as well as the factors influencing the reliability of the operator. The third part of the thesis contains a proposed methodology for assessment of human factor impact on safety of industrial furnaces. Within the methodology performance shaping factors are stated, qualitative and quantitative assessment of human factor impact on safety of industrial furnaces is made and the system integration of the knowledges into the developed methodology is proposed – qualitative model for improvement of system state. The methodology is further verified on a real equipment – a hardening furnace.

The diploma thesis deals with the topic of human failures during the risk activities. The aim of the work is to apply risk analysis to the operation of a selected unnamed company that processes vegetables. The thesis is divided into three parts. In the first part, the theoretical basis is discussed and serves as a basis for a better understanding of the topic and subsequent elaboration of the analytical part. The analytical part focuses on the characteristics of the selected company, organizational structure, working positions and the operation itself and analyses these issues with the focus on human factor. The last part of the diploma thesis is dealing with suggestions leading to the prevention of human failure in risk activities. The aim of these suggestions is to improve the situation of the company.
