Checking of the Situation Behind the Vehicle
Jánošík, David ; Bucsuházy, Kateřina (referee) ; Belák, Michal (advisor)
The diploma thesis deals with the issue of controlling the situation behind the vehicle. The first part of the thesis summarizes the knowledge about drivers, their reaction time and vehicle response, the construction characteristics of vehicles designed to control what is happening behind the vehicle, and the possibilities of measuring the duration of glances in the form of eye tracking. The analytical part contains an analysis of the duration of glances in the rear view mirrors depending on the mirror, the situation and also the driving manoeuvre during the day time. The data was obtained from video recordings of 12 drivers in normal traffic conditions. The duration of the saccades and fixations of glances was evaluated depending on the mirror used, in individual situations and also for selected driving manoeuvres. The conclusion of the analytical part is devoted to the comparison of the duration of glances during selected driving manoeuvres when exposed to stimuli as well as to the comparison of the differences in individual age groups of tested drivers.

Application for Practicing Rapid Reading Techniques
Sokol, Miroslav ; Seeman, Michal (referee) ; Herout, Adam (advisor)
Main goal of this bachelor´s thesis is creation user interface for correct fast reading practise. Four moduls train various abilities of human eyes in regard to average and advanced reader. Application was created as WinForm and thematically is connected with human sight, which hide incredible potential for most of people. The bachelor´s thesis analyse features of eye, individual types of exercises, implementation, concrete developement of user interface and users reactions from their own testing.

Methods of fixation of the upper limb fractures
Litera, Jan ; Marcián, Petr (referee) ; Florian, Zdeněk (advisor)
The presented bachelor thesis is focused on current methods of a fixation of upper limb fractures. Part of the thesis is a literature review and a description of the upper limb anatomy. This is necessary to solve the problems associated with upper limb fractures. The history of the treatment of upper limb fractures enables to gain an insight and a benefit of the current methods of the fixation of the upper limb. Based on the acquired knowledge, there is created a simple computational model of a humeral fracture fixation using a LCP and a classical plate. The computational model for the specific load models was solved in the Ansys Workbench 18.2 computing system. The biomechanical analysis based on the results presentation of the solution of the described simple model showed differences between the application of the LCP and the classical plate.

Strain-Stress analysis of pig femur
Legerský, Radek ; Valášek, Jiří (referee) ; Florian, Zdeněk (advisor)
This master’s thesis deals with the strain-stress analyses of the pig femoral bone in physiological and pathological condition. Pathological condition is determined by a significant defect in diaphysis of the bone fixed by using direct angular stable locking plate with screws. The thesis describes the creation of computational models with special focus on bone tissues models of material, which are based on analysis of digital images from computed tomography (CT). There are created and analyzed three types of computational models: the first one corresponds to physiological condition of femur, the second one to femur with significant defect and fixation plate and the third one to femur with significant defect, fixation plate and rod. Every model is loaded in three ways: the first of them simulating the experimental conditions of pressure testing of the femur, the second one bone stress in the sagittal plane and the third one stress by using load determined from probational release of the pig hind limb. Strain-stress states are determined by finite element method using Ansys computational system. Gained results of stress and strain are compared with experimental measurements. The thesis presents a basic idea of the mechanical behavior of porcine femur and porcine femur with significant bone defect.

Financing Options for Housing in the Czech Republic
Poul, Michal ; Vojtěch, Dušan (referee) ; Hanák, Tomáš (advisor)
This diploma thesis „Financing options for housing in the Czech Republic“ is focused on the issues connected with financing one´s own housing. The goal of this work is mainly to introduce the issues and possibilities of financing housing of the citizens of the Czech Republic, analyze products that could be used while financing housing and compare the costs of financing housing, while using different bank products. In the theoretical part of the work, we obtain knowledge intentions and developments of housing policy in the Czech Republic; we clearly introduce with the products that are helpful while financing housing and their combinations. Insurance products are also mentioned in the thesis. Those products can protect citizens against unwanted influences during the period when they pay off their loans. We can also find here the recent development of loan products and bank market in the Czech Republic, its current offers and overview of its products, from which citizens can choose the most suitable one for their needs. Practical part of the thesis deals with the comparison and research in the least costly way of financing housing in three different time horizons with the help of one product or a combination of products.

Stress-Strain Analysis of Plate for Fixing Proximal Tibial Fracture
Votava, Tomáš ; Chamrad, Jakub (referee) ; Marcián, Petr (advisor)
This master thesis is focused on stress-strain analysis of tibia with fixed proximal tibial fracture. Two types of fixation were considered, for each one two variants of solution were made. In the first part of this theses is presented a review of available literature connected with stress-strain analysis of tibia with fixed proximal tibia fracture. Next one is presented a research study of anatomy and biomechanics focused on lower limb. In the last part of research part are presented proximal tibial fractures and way of their fixation. Computational modeling using finite element method was used as solution method of stress-strain states. ANSYS software was used for solution. Total displacement, contanct pressure between femoral articular surface and meniscus, stress on plate and screws and strain in tibial bone tissue were analysed. Assesment of bone tissue state was made on the basis of Frost's hypothesis.

Biomechanical study on upper extremity fixation
Rafaj, Svatomír ; Marcián, Petr (referee) ; Florian, Zdeněk (advisor)
This bachelor’s thesis deals with fixation and biomechanical aspects of fractures of the upper limb. The first part of the thesis discusses anatomy, knowledge of which is necessary for effective fixation of fractures. It describes the history of inner fixation of fractures and modern curing methods of fractures with a focus on locking compression plates. The second part of the thesis discusses strain-stress analysis of assemblage of humerus and applied locking compression. Computational model was created with the support of ANSYS Workbench 16.0 and SOLIDWORKS 2016 software. Computation was executed by finite element method using ANSYS Workbench 16.0 computational systém.

Strain-stress analysis of fixed bone of foot
Zapletal, Jakub ; Fuis, Vladimír (referee) ; Návrat, Tomáš (advisor)
This diploma thesis deals with analysis of the rigidity of different variations of foot fixations. In the thesis there is a description of elementary anatomy of foot and its patology. Furthermore the possible corrections of hallux deformities and chosen fixators are described. The problem of analysis is soluted by the method of finite elements. The thesis also includes steps of geometery model creation based on 3D scanning. Three differents types of fixations are compared in this thesis and each of them is created in two different levels of details. There is a comparation, analysis of final solutions and chosen influences on the rigidity in the conclusion.
