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.

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.

Design of bike holder for trams
Korejz, Jiří ; Rubínová, Dana (referee) ; Haltof, Vladimír (advisor)
The topic of this bachelor thesis is The design of the bicycle holder for the tram. Contracting authority of this project is the Škoda Transportation company, which participate in consultations with the purpose of producing the final product. The thesis deals with the analysis of the current state and the design of the bicycle holder. The aim is to design bicycle holder which will be convenient for placing it to the multipurpose space of the tram.

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.

Stents and their applications in medicine
Sokl, Antonín ; Němec, Karel (referee) ; Molliková, Eva (advisor)
The aim of this bachelor thesis, which deals with types of stents and their use in medical area, is the provision od detailed reserches of the most frequently used biomaterials, namely details of metals, ceramics, polymers and composites, considering the suitability of their use for the production of substitutes for particular human body structures. The introductory chapters are devoted to external and internal fixation for fractures, dental implants and replacement of renal function. The following chapters deals with stents and their possible variations, especially the chapters are about esophageal stents, prostatic stents and ureteral stents. The final part of this thesis contains a detailed definition of coronary stents, their functional and shape modifications.

Fixation of the biological samples
Brachtl, Martin ; Jiřík, Radovan (referee) ; Krátká, Lucie (advisor)
The aim of thesis is acquaint with possibilities of fixation biological tissues. Choose a suitable tissue and fix it with formaldehyde and another fixator. Last but not least make measurements which determine effects of formaldehyde on the relaxation time of biological tissues. Mice brains were chosen as a suitable for tissues fixation. Measuring effects of formaldehyde and another fixator to relaxation time carried out at the Institute of Scientific Instuments Academy of Sciences of the Czech Republic.

Application for Practicing Rapid Reading Techniques
Padyšák, Jan ; Beran, Vítězslav (referee) ; Herout, Adam (advisor)
The aim of this bachelor´s thesis is to create a training program for rapid reading techniques. This created application is implemented for training exercises of various abilities of human eye. For each of these exercise, we can choose the difficulty according to the experience of the reader. The program was created in development environment NetBeans IDE 7.0.1 in Java. In this thesis I describe tips for reading text and a graphic user interface. It also contains a description of selected exercises and their implementation. In the last part of this work I focused on testing this application.
