In my master thesis I deal with the issue of the identity of 19th century Russian society and the role of the Volga River in it. I focus on the characterization of Russian identity in the broadest sense, on the relationship of human society to nature, and on two case studies from the Upper Volga region. In the theory of Russian identity I consider four of its characteristic features - ambivalence, patriotism, spirituality and sentimentalism - to be crucial. The analysis of the relationship between human society and nature includes a section devoted to the reasons for human attachment to landscape, discusses the concept of national landscapes, and presents the dominant idea of the Russian landscape at the end of the 19th century. The last section is devoted to research on the role of the Volga River in the self-identification of the inhabitants of the Upper Volga region. In a study of the worship of the source of the Volga and in research on folklore, I note the attitude of various influences towards this river and, on this basis, define the place of the Volga River in the life of different social classes. The conclusion of my study is that the role of the Volga River in the life of the Upper Volga inhabitants was in many ways the same as its role in the national social discourse, but quite out of...

Variety of problems can appear when introducing dental implants, especially to in the maxilla. Biggest problems are caused by insufficient quality and volume of the bone tissue of the alveolar process. This thesis focuses on stress-strain analysis of an implant introduced in the maxilla. Mechanical interaction between the implant and bone tissue is solved using computational modelling with the finite element method. From analysis of results, it was discovered that deformation and tension of the implant are influenced by the direction of the load, osseointegration and thickness of the cortical bone tissue. In the anterior region, it is necessary to work with other types of load than axial.

The diploma thesis deals with a design of a steel loadbearing structure of a footbridge over a river. The footbridge is located in Svitavy and is designed for span length of 60 meters. The construction is preliminarily designed in two variants. A part of the thesis is also a comparison of both variants. The chosen variant has been elaborated in detail. It is an arched construction with a semi-through bridge deck. The main loadbearing structure consists of a pair of arches that support the steel-concrete bridge deck by means of rods in tension. The main loadbearing arches are inclined from the vertical plane towards the bridge axis and are fixed at the ends. All steel parts are designed from S355 steel, except for the rods that are designed from S460 steel. The bridge deck is designed from C 35/45 concrete. The spatial rigidity of the structure in the transverse direction is achieved by means of arc sway bracings.

The main idea of this thesis is a propose by designing filters in Mathcad program. This paper deals with a basic principle in filters design and these principles are implemented into the Mathcad program. In the introductory part is described aproximation which was used in Mathcad script. In the other parts of this project is described program which was created on designed filters.

The aim of the thesis is to study the possibilities of the electronic frequency ?lter com- posed of active elements operating in current mode. The main opportunities lie in the change control parameters, most are marginal or quality factor frequency. As the active elements are considered especially CC (Current Convejor), controllable current ampli?er DACA (Digitally Adjustable Current Ampli?er) or combination with the current tracker MO-CF (Multiple Output Current Follower). Another part will focus on the management of the above parameters using digital potentiometers and choosing the appropriate ?lter structure. The ?nal task was to digital control parameters using a PC and measuring its properties.

In this diploma thesis is accomplished description of existing condition of decorating linear tractive unit. Analysis of safety requirements for linear tractive unit is also accomplished. Eligible construction concept of frame of electromechanical linear tractive unit is chosen. Selection and calculation of ball screw and nut is made also with draft of its eligible support . Choose of eligible engine and clutch for gearing of engine torque from engine to the ball screw is done too. Further is designed eligible concept of gearing of the rotary motion of ball screw to straight motion of bottom pulley block, which now interacting with upper firm pulley block provides lifting of tensile rod with coulisse.

The Diploma thesis deals with the design solution of multi-functional machining centre, especially with one of its parts – the design of the slide ram and vertical feed incl. the choice of convenient tool heads for the slide ram. The introducing part deals with the numerically controlled machines and centres generally, especially with the portal-type ones. It contains description of individual machine parts including examples of accessories from product plans of domestic and foreign producers. The second part of the Diploma thesis contains calculations and design solution of the slide ram and feed including the choice of the most suitable accessories applicable for this purpose. In the final phase the model of the slide ram has been introduced in the imersion virtual reality and integrated in the complete machine design. The Diploma thesis has been elaborated using the relevant technical literature.

The purpose of this diploma thesis is a design of frame, crossbar, transverse feed, sliding feed of multifunctional machining center. In the first part, there is a brief research of history of machine tool conducted, division of machining centers, materials for frame construction, alternatives of drives of sliding axis. Further, I carry out an analysis of parameters of compeeting machine tools, from which I selected the parameters of our machine. Frame project of the machine, propulsion of axis X and Y, kinematic connection of axis X,Y,Z. Frame of machine is analysed by Finite Element Method. Over the scope of this work I suggest a solution for covering of linear axis as well as their measuring of actual position. 3D model of frame and drives of machine are included in this work. A complete formation has been introduced into the immersive virtual reality environment.

Design of multi-functional machining center The purpose of this diploma thesis is a design of turning table for multi-functional machining center. The first part is the background research of multi-functional machining centers, rotary tables, chip management and brief overview of chosen machining center’s manufacturers. The sphere of using of the designed machine, including parameters of turning table, and its basic parameters are determined on the basis of this research. Afterwards, the variants of turning table drives are drawn up and one variant of calculation and construction is made. Design of clamping desk and chip management of the machine is also made. Above a specified framework of this thesis, simplified machine foundation design and anchoring of machine parts to this basis is performed. The work also includes a 3D model of turning table and substructure. The complete set of constructed machining center was brought into immersion virtual reality environment.

This master thesis deals with a concept of two columned shelf stacker’s upper beam. The first part contains a research of storage systems used in logistics and a description of the shelf stack’s basic parts. The second part is dedicated to the draft of the pulley arrangement with a rope calculation, pulleys and shafts, in the same the draft of the pulley attachment to the rope leading to the counterweights. It is followed by the concept of the couple winch drive ensues synchronized with the electronic cardan. The final part depicts the dynamic analysis of the lifting truck’s movement in the dependence on the load size and distribution respecting the dynamic effect of the counterweight act.
