Deformačně napjatostní analýza prvků totální náhrady trapéziometakarpálního kloubu / Deformation and stress analysis of the parts of the total replacement of the trapeziometacarpal jointSvojanovský, Tomáš January 2015 (has links)
The presented diploma thesis builds on author’s bachelor’s thesis of the similar name which was focused, in particular, on rhizarthrosis. Because of this joint disease, implantations of the total joint replacement are performed. The bachelor’s thesis also served as a familiarization with the finite element method and contact analyses issues, giving a theoretical framework for this diploma thesis. As opposed to that, the diploma thesis aims entirely at deformation and stress analysis of the total replacement. The main objective is to carry out analyses of different variants of geometric models. In addition, there is a tendency to analyze contact pressures of advanced model concerning all the total replacement, bone tissues, ligaments and tendons guaranteeing the static equilibrium of components. The bachelor’s thesis has been developed in ANSYS Workbench, whereas the diploma thesis in ANSYS APDL. Work in APDL allows user to control better over the entire computational process, however, requires more skills and theoretic knowledge. Contact analyses bring a lot of problems associated with convergence of procedures and accuracy of results. Therefore, explanations of important terms and set of recommendations are included for the purpose of easier solving of the contact problems.

Rozvoj inverzních úloh vedení tepla řešených s využitím optimalizačních postupů a vysokého stupně paralelizace / Development of Inverse Tasks Solved by Using the Optimizing Procedures and Large Number of Parallel ThreadsOndroušková, Jana January 2015 (has links)
In metallurgy it is important to know a cooling efficiency of a product as well as cooling efficiency of working rolls to maximize the quality of the product and to achieve the long life of working rolls. It is possible to examine this cooling efficiency by heat transfer coefficients and surface temperatures. The surface temperature is hardly measured during the cooling. It is better to compute it together with heat transfer coefficient by inverse heat conduction problem. The computation is not easy and it uses estimated values which are verified by direct heat conduction problem. The time-consuming of this task can be several days or weeks, depends on the complexity of the model. Thus there are tendencies to shorten the computational time. This doctoral thesis considers the possible way of the computing time shortening of inverse heat conduction problem, which is the parallelization of this task and its transfer to a graphic card. It has greater computing power than the central processing unit (CPU). One computer can have more compute devices. That is why the computing time on different types of devices is compared in this thesis. Next this thesis deals with obtaining of surface temperatures for the computation by infrared line scanner and using of inverse heat conduction problem for the computing of the surface temperature and heat transfer coefficient during passing of a test sample under cooling section and cooling by high pressure nozzles.

Aproximace, numerická realizace a kvalitativní analýza kontaktních úloh se třením. / Approximation, numerical realization and qualitative analysis of contact problems with frictionLigurský, Tomáš January 2011 (has links)
Title: Approximation, numerical realization and qualitative analysis of contact problems with friction Author: Tomáš Ligurský Department: Department of Numerical Mathematics Supervisor: prof. RNDr. Jaroslav Haslinger, DrSc., Department of Numerical Mathe- matics Abstract: This thesis deals with theoretical analysis and numerical realization of dis- cretized contact problems with Coulomb friction. First, discretized 3D static contact prob- lems with isotropic and orthotropic Coulomb friction and solution-dependent coefficients of friction are analyzed by means of the fixed-point approach. Existence of at least one solution is established for coefficients of friction represented by positive, bounded and con- tinuous functions. If these functions are in addition Lipschitz continuous and upper bounds of their values together with their Lipschitz moduli are sufficiently small, uniqueness of the solution is guaranteed. Second, properties of solutions parametrized by the coefficient of friction or the load vector are studied in the case of discrete 2D static contact problems with isotropic Coulomb friction and coefficient independent of the solution. Conditions under which there exists a local Lipschitz continuous branch of solutions around a given reference point are established due to two variants of the...

Geneticky modifikované rostliny ve vztahu k řešení problematiky globálních klimatických změn / Genetically modified plants in relation to solving the issue of global climate changesNedělová, Jana January 2014 (has links)
The theoretical part of the diploma thesis summarizes basic facts related to the global climate change and provides up-to-date knowledge on the issue of genetically modified plants more resistant to stress factors of environment, including specific examples of strategies regarding preparation of genetically modified plants resistant particularly to abiotic stress. Although genetically modified plants and global climate changes belong to very important and current issue which public and foremost young generation should be sufficiently aware of, contemporary biology books and high school framework educational program pay to the issue very little attention. Therefore, the goal of this thesis is not only to summarize the basic facts and current knowledge regarding this issue but mainly to handle the issue in didactic level in the form of activating learning tasks. There were 28 learning tasks created in the thesis that gradually in unconventional way familiarize students with the issue of genetically modified plants and with the impacts of climate changes. Students must actively acquire information from accompanying materials to address the tasks properly, think critically over them, utilizing acquired knowledge and experience from the past to some extent. Fourteen tasks were chosen from the file created which...

John Henry Newman - life and work in the context of the struggle for the universality of the Church ThDr. JUDr. Květoslav Tomáš Krejčí, M.Phil. (Oxon), Ph.D. In the absence of any Czech language monograph since 1939 (or 1947), the thesis presents a summary of the life and work of John Henry Newman (1801-1890). It also contains an original Czech translation of selected writings. Due to its character of a thesis in history of theology, the work also introduces Newman as a writer. A particular attention is given to the reception of Newman's thought in France and Germany, his relationship with Catholic modernism and liberal theology as well as to Newman's impact on the documents of Vatican II.
