War Injuries from Past to Present
Smrčka, V. ; Mádlová, Vlasta
The symposium was conceived as a meeting of Ph.D. students studying palaeopathological issues. Due to a great interest in this subject matter it was finály extended by further invited scientific lecturers who are concerned with the history of medicine. The Symposium covered this subject matter not only from the Neolithic Age to the World War I but also to the present days.

Modelování profilů rychlosti větru naměřených sodarem v komplexním terénu
Hošek, Jiří
The wind profiles with two Doppler sodars were measured in wide range of synoptic situations in Ore mountains (Erzgebirge) and in the region of Orlické hory (mountains), both in the Czech republic. Ore mountains represent the region most suitable for construction of wind turbines in the Czech republic. Concerning the observed wind profiles, their generalization may serve for improvement of precision of the simulated wind profile fields. In the second part of the work, we performed the modelling of wind speed profiles in the complex terrain of above-mentioned mountain ranges. We have applied the non-hydrostatic meso-scale models KAMM and PIAP. The numerical simulations with the models were performed for different situations of the ambient flow, described by geostrophic wind speed and direction, and temperature stratification.

Physical and mathematical modeling of effects of velopharyngeal insufficiency on acoustic characteristics of human vocal tract
Horáček, Jaromír ; Vampola, T. ; Veselý, Jan ; Růžička, P.
The effects of velopharyngeal insufficiency or clefting on acoustic frequency-modal characteristics of human supraglottal spaces are investigated for the Czech vowels /a/ and /u/. Finite element (FE) modelling is supported by experimental investigation using a physical model of the vocal and nasal tract fabricated by the rapid prototyping technique from the FE model.

Measurement and computation of acoustic characteristics of a simplified vocal tract model for phonation of vowel /a/
Kryštůfek, J. ; Vampola, T. ; Horáček, Jaromír ; Veselý, Jan
The paper is focused on experimental verification of 3D modeling of the acoustic characteristics of human vocal tract for phonation of vowel /a/ by the finite element method. The computational and experimental modal analyses were carried out on the mathematical and physical models of the vocal tract. The acoustic pressure computed by transient analysis in time domain is compared with measured resonant characteristics in frequency domain.

Předběžné výsledky modelování rázové napjatosti hlasivek s použitím aeroelastického modelu produkce hlasu
Horáček, Jaromír ; Laukkanen, A. M. ; Šidlof, Petr
Voice problems are kown to be common among voice professionals, e.g. teachers. More information is needed on biomechanical forces related to voice production in order to be able to set safety limits for voice use in various professions. Impact stress, defined as the impact force divided by the contact area of the vocal folds, is an important variable in quantifying the mechanical load posed on the vocal fold tissue during voice production.

Accurate positioning of pneumatic drives
Volf, Marek ; Nevrlý, Josef (referee) ; Marada, Tomáš (advisor)
Thesis starts with brief overview of the present role of pneumatic actuators. Further research is carried out in modelling and control of pneumatic actuators. A basic overview of thermodynamic laws is presented. These laws are used to assemble a mathematical model of the pneumatic drive. Subsequently the identification of model parameters is shown. A controller is propřed using fuzzy PID algorithms. Results are compared with the conventional PID controller.

Perspektivy užití MKP v lomové mechanice
Kozák, Vladislav
The possible application of the finite element analysis modelling fracture behaviour of components with defects are tested.The approaches based on the GTN model and cohesive model are compared.

The Concept of Baptism by Jan Bechyňka in the Traktát o viděních a pokušeních zbožného mládence (Tractate of Visions and Temptations of Devout Youth) and in the Treatise O křtu zvonu (On baptism of the Bell).
Beranová, Bohumila ; Rejchrtová, Noemi (advisor) ; Halama, Ota (referee)
The thesis deals with conception of baptism by utraquist priest Jan Bechyňka. At first the figure of the peculiar writer and theologian after being introduced is integrated into historical connections of the jagellonian era. The chapters that follow aim at the particular topic. Bechyňka ́s view of pedobaptism drawn from a long passage about commitment of baptism from his Traktát o viděních a pokušeních zbožného mládence [The Tractate on Visions and Temptations of Devout Youth] is compared with pedobaptism in Chelčický ́s Zprávy o svátostech [Reports of Sacraments] and with baptism in general of another Chečický ́s work - Rozpravy [Disccusions] in Parisian manuscript. At first I had intended finding out paralles between mentioned thinkers, however certain differences have appeared as well, not in essential facts. In the case of Bechyňka ́s tractate O křtu zvonu [On Baptism of the Bell] I give an interpretation to it in the concrete. The last chapter deals with utraquist baptismal praxis in the early modern times and in the present day and in general describes baptismal rites of these times. As a apendix I add Bechyňka ́s tractate O křtu zvonu [On Baptism of the Bell] with a commentary and transcriptional notes. Powered by TCPDF (www.tcpdf.org)

History of the town of Janovice nad Úhlavou till 1848. Historical monograph
Lhoták, Jan ; Maur, Eduard (referee) ; Ebelová, Ivana (advisor)
The offered thesis deals with the history of the town Janovice nad Úhlavou until the year 1848, it is the locality situated in the southwestem Bohernia not far from Klatovy. In the first chapter, the author presents a basic overview of the study of the regional history in the Czech countries and its further prospects, then he expands on the heuristic basis, from which he proceeded when elaborating the monograph. After evaluating the geographical conditions of the locality, a prehistoric development of the Klatovy region is observed, which is up to this day impeded by the lack of executed archeological researches. The second chapter deals with medieval colonization of the whole Klatovy region, in which the accent is put on the significance of historical communications which it also describes and evaluates in the framework of the region being explored. On the basis of acquired facts, it subsequently outlines the basic contours of the settlement progress. The fifth chapter already refers directly to the history of the town in the Middle Ages. The appearance of the surrounding country in the past is observed and especially the medieval history of the knight order of Janovští z Janovic. Both the basic farnily line, which owned Janovice nad Úhlavou and builded here a church and a castle, and main features of...

Strength analysis of cutting tools
Petrlíková, Helena ; Madaj, Martin (referee) ; Zouhar, Jan (advisor)
This work is focused on the stress-strain analysis of a cutting tool. At the beginning, the study of available literature and scientific articles relating the topic is carried out. The solution of stresses and strains in whole real system has been carried out based on the computational simulation using the finite element method (FEM). The work contains a detailed description of the creation of the computational model. Model of geometry of the system has been created in the SolidWorks program. Computational simulation including the solution was implemented in the ANSYS Workbench program as well as in the classical environment of ANSYS 12.0. This work includes the presentation of results and subsequent stress-strain analysis of the cutting tool. Last part of this work deals with the modal analysis and harmonic analysis of cutting tools made in classical environment of ANSYS program.
