Prevention of Human Factor Failure in Hazardous Activities
Jíra, Aleš ; Balgová, Zuzana (referee) ; Kruliš, Jiří (advisor)
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.

Trends and forecasts in the technology of artificial disc replacement
Bodlák, Daniel ; Jelen, Karel (advisor) ; Říha, Michal (referee) ; Jíra, Aleš (referee)
1/1 škola: UNIVERZITA KARLOVA V PRAZE, Fakulta tělesné výchovy a sportu disertační práce: "Trends and forecasts in the technology of artificial disc replacement" autor: Ing. Daniel Bodlák datum: prosinec 2023 Abstract: The aim of the work was the study of current and new directions and trends in intervertebral disc replacement technology, a critical evaluation of current methods using implants for the treatment of degenerative disc disease, as well as a forecast of further development. The work also contains the related results of the collaboration on the optimization of the total "ball and socket" lumbar disc replacement within the project TA01010860 "Solving the problem of intervertebral disc replacement using modern knowledge, engineering methods and progressive technologies". In the part of the dissertation, focused on theoretical starting points, the attention is paid first to the intervertebral disc itself and its various aspects, from anatomy, through biomechanics and degenerative diseases, to the issue of implants for its partial or even total replacement. Subsequently, current trends and progressive methods of treatment are processed. The results section begins with a description of the methods used and then presents the results themselves, both from literature research and experimental work....

The Political Debate on Immigration in the UK between 2010-2015
Jíra, Alexandr ; Váška, Jan (advisor) ; Najšlová, Lucia (referee)
This thesis focuses on the political debate surrounding immigration, especially in the two prominent political parties in Great Britain - the Labour Party and the Conservative Party. Its main timeframe is between 2010 and 2015, however to fully contextualise the issue some earlier data is used. This text analyses the pre-election debate of the main political parties in the United Kingdom. It looks at immigration as a topic in their manifestos and during pre-election talks. The thesis aims to map the change in approach of the main political parties during the time when they switched positions as government and opposition.

Energy absorption of cellular foams in high strain rate compression test
Králík, V. ; Němeček, J. ; Jíra, A. ; Fíla, Tomáš ; Zlámal, P.
Aluminum foams are structural materials with excellent energy absorption capacity jointed with very low specific weight and high stiffness. Products of aluminum foams are used in a wide range of structural and functional applications (e.g. as a part of composite protection elements) due to its attractive properties. Full characterization of deformation behaviour under high-strain rate loading is required for designing these applications. The aim of this study is to compare stress-strain behaviour and energy absorption of the aluminium foam structure with conventional energy absorbing materials based on polystyrene and extruded polystyrene commonly used as protective elements. The compressive deformation behaviour of the materials was assessed under impact loading conditions using a drop tower experimental device.
