The device for measuring of camshafts timings
Jozíf, Lukáš ; Mazal, Pavel (referee) ; Mazůrek, Ivan (advisor)
Bachelor’s thesis is focused on constructional concept of device for measuring of camshafts timing and its wear-out. After short introduction and definitions of basic concepts there are problems of cams design analyzed and overview of the commercially offered devices is mentioned. Next part focuses on construction of the proper device including design documentation. Procedure of measuring with the device and example of some data evaluation is described. In the conclusion I evaluated constructional and economic aspect the whole concept.

Methodological aspects of active place avoidance task
Bahník, Štěpán ; Stuchlík, Aleš (advisor) ; Němec, Pavel (referee)
The active place avoidance task represents one of the methods of the study of animal cognition. In this task, a subject is put on a rotating circular arena and avoids invisible sector that is stable with respect to the room. Rotation of the arena means that the subject's avoidance must be active, otherwise the subject would be moved in the punished sector by the rotation of the arena and a slight electric shock would be administered. The experiment described in the present work explored the effect of variable arena rotation speed on the ability to avoid the punished sector. Rats in a group with a variable arena rotation speed learned to avoid the punished sector with the same speed and attained the same ability to avoid the sector as rats in a group with a stable arena rotation speed. The only difference between the two groups was found in a preferred position within the room. No difference was found between the two groups in the dark phase, where the rats could not use orientation cues in the room. Only one rat was able to learn the avoidance of the punished sector in this phase. The results of the experiment suggest that idiothetic orientation and interval timing are not crucial for learning of the avoidance of the punished sector. However, idiothetic orientation is sufficient for the avoidance of the...

Quantum and tempo of population ageing process in the twelve countries of the former Soviet Union: Challenges, opportunities and public policies
Mustafina, Marta ; Kučera, Tomáš (advisor) ; Kalibová, Květa (referee) ; Sidorenko, Alexandre (referee)
Quantum and tempo of population ageing process in the twelve countries of the former Soviet Union: Challenges, opportunities and public policies Abstract Population ageing is an omnipresent phenomenon which brings along unprecedented challenges to socio-economic development, especially to employment, social security and public health sectors. The broad goal of this doctoral thesis was to demonstrate that it is time to recognize the importance of population ageing and its dynamics even in the countries with relatively young population structures and to take urgent action through implementation of corresponding policy interventions in order to mitigate and eliminate the upcoming negative consequences and utilize potential opportunities. Research on population ageing in both more and less developed countries is abundant. However, amidst numerous studies, countries of the former Soviet Union remain largely overlooked. Besides, the quantum and tempo of population ageing have not been adequately addressed in the existing literature worldwide. This research addresses, to the best of our knowledge for the first time, those issues. Holistic approach to gap analysis was adopted to guide this study. The analysis was performed in three steps. The first step incorporated the identification and analysis of the observed...

Analysing fertility developments in selected European countries between 1970 and 2014 using alternative methods
Vachuška, Jakub ; Kurtinová, Olga (advisor) ; Šťastná, Anna (referee)
Analysing fertility developments in selected European countries between 1970 and 2014 using alternative methods Abstract Transversal fertility indices as the total fertility rate are distorted by tempo effect when timing of childbearing is changing. New indices as the tempo-adjusted total fertility rate remove this distortion and give another perspective on fertility trends in countries with present tempo effect. These countries are former Eastern Bloc countries and other European countries. This thesis uses the tempo-adjusted total fertility rate and data from Human Fertility Database to describe tempo distortion in fertility level in Sweden, Norway, Czechia, Slovakia, Estonia and Lithuania in period 1970-2014. A more detailed analysis by parity in Sweden and Czechia is conducted in the same period. Negative tempo effect has been present from 1970s in Sweden and Norway and then from 90s in the countries left with fertility postponement being very widespread. The tempo effect level in Sweden and Czechia was substantial at parity one and diminishing with higher parities. Keywords: fertility, timing, level, postponement, adjusted total fertility rate, tempo effect Number of characters without blank spaces: 138 653

Regional differentiation of fertility in the Visegrád Four countries at NUTS 2 level in the period 1993-2016
Vachuška, Jakub ; Šídlo, Luděk (advisor) ; Hašek, Oldřich (referee)
Regional differentiation of fertility in the Visegrád Four countries at NUTS 2 level in the period 1993-2016 Abstract Bachelor's thesis deals with the regional differentiation of selected fertility characteristics in the Visegrad Four countries between 1993 and 2016. Part of the thesis is dedicated to discussing reproductive behaviour changes in former socialist countries which started in the 1990s. The thresis puts an emphasis on the clarification of the causes of these changes, with the second demographic transition and economic changes mainly discussed. The section analysing regional differentiation of fertility is conducted at NUTS 0 level for single years and at NUTS 2 level using eight three-year periods. Regional differentiation of the rate, timing and age structure of fertility is analysed. During most of the period examined, convergence of the rate and timing of fertility occurred. Some regions as regions of capital cities were distinguished by different fertility characteristics. During the analysed period there is a noticeable significant shift in fertility age structure towards higher ages in all regions, and this gradually affected fertility rate in all of them. Keywords: regional differentiation, fertility, Visegrad Group, rate, timing
