Detection of car accident and collapse by Android smartphone
Repčík, Tomáš ; Ronzhina, Marina (referee) ; Maděránková, Denisa (advisor)
Bachelor thesis “Detection of car accident and collapse by Android smartphone” describes theoretical basics of a collapse and a car accident. With help of 23 volunteers, data has been collected from daily tasks, simulating collapses and driving. Based on that a model with capability to classify a car accident was created. The detection of collapse uses neural network with accuracy of 86 %. The detection of car accident uses accelerometer and GPS. To indicate the car accident a high acceleration created by the accident and absence of moving car is required. Next, the application was tested by all available data and by the volunteers in daily life, who used the application for 520 h.

The collapses of distant worlds
Kozina, Václav ; Halbich, Marek (advisor) ; Budil, Ivo (referee) ; Horák, Miroslav (referee)
Diploma thesis "The collapses of distant worlds" deals with interpretations of the conquista of Mexico and Peru (i.e. the conquests of Aztec and Inca empires). The basic question, which all the works considering the conquista deal with, is: how could the arrival of small groups of Spanish conquerors disrupt great Indian empires in such a short time? My thesis has two main goals: to define the typology of interpretations of the conquista and offer my own interpretation which places emphasis on the role of mentalities and cultural complexes. I have distinguished four basic types of interpretations of the conquista: 1. the metaphysical ones; 2. the technological ones; 3. the environmental ones; 4. the mentalistic ones. I used the conception of mentalities (derived from the work of Lucien Lévy-Bruhl) and the system conception of cultur, where I worked with the term "cultural complex" especially. After my approach the conquista represented the clash between two different types of mentalities: the archaic one (which Indian societies featured) and the literary one (which was developed in European societies). Differences in mentalities and cultural complexes provided advantages to the Spaniards in their struggles with the Aztecs and the Incas. So finally the Spanish conquest of Indian empires is...

The parasitic microorganisms in immunodeficient and healthy population of honebees (Apis mellifra)
Bičianová, Martina ; Hubert, Jan (advisor) ; Titěra, Dalibor (referee)
Immunodeficient honey bee (Apis mellifera) colonies suffer from broad range of parasites including eukaryotic protozoa. Despite this fact, the eukaryotic parasites are still poorly documented in the Czech Republic. The presence of eukaryotic parasites (Nosema ceranae, Nosema apis, Crithidia mellificae and Apicystis bombi) was observed in different apiaries in the Czech Republic. The samples were taken in 9 apiaries in 53 beehives during the 2014/2015 season. From each beehive, 10 adult of honey bees were taken from the peripheral comb in triplicate. DNA was isolated from every sample of honey bees. The parasites were detected by polymerase chain reaction (PCR) with specific primers. The treatment fall of parasitic mite Varroa destructor was obtained from beekeepers for season of 2014. Crithidia mellificae was detected by 5 types of specific primers (SEF, SER; SSU, SSU rRNA, Cyt b, Tryp cyt b) and positive amplicons were cloned and sequenced. The obtained sequences were compared with GeneBank and showed similarity from 98-100% to sequences of Lotmaria passim (Trypanosomatid). Crithidia mellificae was not detected. L. passim had prevalence of 79,2% and is reported in the Czech Republic for the first time. Primer Tryp-cyt b is recommended for the routine detection of L. passim. Nosema ceranae was...

Temporary consciousness disorders in providing the prehospital urgent care
Tyčová, Monika ; Marsová, Jana (advisor) ; Pekara, Jaroslav (referee)
The abstract The temporary state of unconsciousness (i.e. collapse, syncope) is a common reason for the emergency medical service intervention. Quantitative consciousness disorders affect patients of all ages. Sudden unconsciousness associated with a fall is usually dramatic for the laymen, but in most cases, this is a non-serious state of the noncardiogenic etiology, also called fainting. These states usually do not require urgent treatment. In contrast, cardiac syncopes, which occur mainly in the older age groups, are less common but have a significantly worse prognosis. Untreated, can result in sudden death of the patient. Mostly these are the collapses conditional cardiac arrhythmias. They account for about 10-20% of all states of collapse and have a very high mortality. Sudden temporary fainting requires careful physical examination and a thorough anamnesis within the first contact. Based on the results, in about half the cases it is possible for the cause of the collapse to be presumed. Though it is not possible to determine the definite cause of the collapse with certainity within the prehospitalurent care, therefore the patient is transported for the physical examination to a medical facility. They are then examined internally, especially cardiologically, and with usage of the adequate investigative...

Mechanical behaviour of variably saturated clay fills
Kostkanová, Vladislava ; Boháč, Jan (advisor) ; Kurka, Jan (referee) ; Vaníček, Ivan (referee)
Mechanical behaviour of variably saturated clay fills VLADISLAVA KOSTKANOVÁ Ph.D. Thesis - English Abstract The excavated overburden from open-cast coal mines is end-dumped in fills. Clay type soil prevails among the filled soils in North-western Bohemia. As a consequence of the character and state of the soil, together with the mining and dumping technology, a typical lumpy structure of the clay fill is formed. The filled lumps range in size and vary in mechanical properties, but stiff to solid lumps up to 0.5 m in size are prevalent. Large and open macrovoids between the single lumps are a characteristic feature of the clay fills. Clay fills exhibit a double porosity structure, consisting of intergranular porosity between the lumps and intragranular porosity inside them. The total porosity of the freshly filled soils can reach 70%. This type of clay fill structure is metastable. This thesis focuses on the problematic behaviour of clay fill soils due to their metastable structure and their partly saturated state. Long-term monitoring of matric suction at depths up to 2 metres in two reclaimed clay fills revealed two different trends. Seasonally-dependent suction oscillations were recorded in the moderate slope of the clay fill in the Bílina mine, while no suction pointing to fully saturated conditions was...

Point Pleasant bridge collapse - casual analysis of the accident
Jagoš, Jiří ; Němec, Karel (referee) ; Válka, Libor (advisor)
The bachelor thesis is focused on the analysis of the causes of the accident of the Silver Bridge, which occurred in 1967, forty years since the introduction of the bridge to the traffic. In the work are discussed in detail all possible causes of the collapse of the bridge on the basis information and facts mentioned both directly in the inquiry reports of committees, as well as in documents and literary sources, dealing with material analysis of the structural nodes of the wrecked bridge. The work carried out critical analysis of the available and relevant information about the crash. The bachelor thesis outlines also the possible causes of the fall and collapse of the bridge from structural point of view and from terms of the material.

Icelandic economy after the crisis and future perspectives on economic development
Plocková, Kateřina ; Bič, Josef (advisor) ; Karpová, Eva (referee)
Diploma thesis deals with the recovery of the Icelandic economy after the financial crisis that affected the country in 2008. The thesis is divided into four main chapters. The first chapter focuses on theoretical view on the financial crisis and the typology of each crisis. The second chapter describes pre-crisis economic development, triggers and the subsequent collapse of the banking sector. The third chapter deals with the impacts of the crisis on selected economic indicators, evaluation of the assistance provided by International Monetary Fund and outlines the issue of capital controls that were relatively controversial element of the IMF program. The last chapter discusses the question of joining the European Union in relation to the crisis and also describes the major difficult point of negotiation, namely fishing.

Ireland and Iceland and the Global Economic Crisis
Bořuta, Lukáš ; Žamberský, Pavel (advisor) ; Bič, Josef (referee)
The main objective of my thesis is to analyze and compare reactions of Iceland and Ireland to financial and economic crisis as well as the aftermath of the crisis and the process of recovery as direct consequence of these reactions. Both states had financial sector couple of times bigger than their GDP before the crisis and after the fall of Lehman Brothers they ran into some serious difficulties. However, states chose very different approaches to deal with a situation. Ireland decided to bailout its banks despite the huge increase in public debt and cost of taxpayers' money. Iceland allowed its banks to default and backed only domestic deposits. In my thesis I also analyze the fact that Ireland is a member of euro area and therefore does not possess independent monetary policy and Iceland has independent floating currency and implications that these facts had during and after the crisis on development of countries. In the last chapter I am analyzing possibilities of future development of economies and potential risks and challenges that lie ahead of them.
