Group theoretical properties of the group generated by the action of the AES-128 key schedule
Appah, Patrick ; Pavlík, Jan (referee) ; Aragona, Riccardo (advisor)
The AES key scheduling algorithm selects the round keys which are xor-ed with the partially encrypted state in each iteration. In this work, we examine the group that arises from the AES-128 key scheduling operation. We show that the smallest group _AES containing and all translations of the message space is primitive. This implies that we cannot have a linear partition of the message space that is invariant under the action of _AES .
Design of spindle for lathe
Novotný, Timotej ; Tůma, Jiří (referee) ; Pavlík, Jan (advisor)
The diploma thesis deals with the design of headstock of turning center. The introduction of the work is devoted to a brief description of turning centers and detailed description of individual parts of headstock. The main part of the work consists of determining the characteristics of the headstock, calculations necessary for design and dimensioning and calculations using the finite element method. The result of the work is a 3D model of the designed headstock and drawing documentation.
Design of the bottom housing manipulator of the toner cartridge
Horák, Jiří ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
This diploma thesis is focused on bottom housing manipulator of the toner cartridge concept, construction and economical analysis. This manipulator should be potentially integrated into the toner cartridge assembling and filling prodution line. Theoretical part of this thesis is focused on manipulation issues and object manipulation. Practical part consists of conception desing part which is followed by multi criteria decision analysis. Next part is focused on Construction and pneumatic scheme. Economical analysis is also part of the thesis. The diploma thesis also contain 3D models of the manipulator and drawing documentation.
A design of self-centering steady rest for CNC lathe
Mjartan, Lukáš ; Pavlík, Jan (referee) ; Tůma, Jiří (advisor)
The subject of this bachelor thesis is the design of a self centering lunette for a CNC lathe. In the beginning of the thesis the problem of clamping on the lathe is analysed. In the next part, research of lunettes available on the market is made. The following section describes the design of the main parts of the lunette. Based on calculations, a 3D model is created. The thesis concludes with an evaluation of the design with emphasis on the possible future production and operation of this device.
Design of a remote-controlled handling truck for transporting material in production
Hurtík, Daniel ; Pavlík, Jan (referee) ; Huzlík, Rostislav (advisor)
This diploma thesis deals with the design and construction of a remote-controlled handling cart for transporting material in production with a maximum total weight of 1,000 kg. The first area is devoted to the current state of knowledge and research in the field of handling carts used for material transport as well as for other applications. Furthermore, in the second part, a system analysis follows, where the important parameters that will have to be observed during the design are listed. In the third area, the proposed solution variants are specified in more detail and the winning variant for all important components and systems is specified according to the calculation procedures. The fourth part is devoted to the calculation and design of essential components, so that they are correctly selected or sized. The next part of the work focuses on the chosen electrical equipment and construction design. The sixth area of work is devoted to the economic evaluation of the developed model against the competitive solution and the last area of work deals with the final evaluation and use in practice.
Optimizing the design of the workshop belt grinder
Vodička, Tomáš ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
This thesis deals with optimalization of already existing design of belt grinder on basis of trial operation and design based on optimalization. In the research part are mentioned basics of grinding and categorization of belt grinders. In next part, the reader is introduced to existing design. Following by analysis of flaws and part about optimalization, where flaws are resolved, and new optimised design is checked by engineering calculations.
Design of a small universal grinder for sharpening tools
Grym, Filip ; Huzlík, Rostislav (referee) ; Pavlík, Jan (advisor)
This thesis deals with the design of a small universal grinder for tool sharpening. The thesis begins with an introduction to the issue of tool sharpening, drilling, milling, and turning. Further, a market research and analysis of user needs is conducted. Based on these findings, several different variants of devices and methods for grinding are proposed, from which one is selected. Based on the selected variant, a 3D model and drawing documentation of selected nodes are developed. The functionality of the design is verified by basic calculations.
Virtual commissioning of a robotic welding workplace
Provazník, Adam ; Pavlík, Jan (referee) ; Vetiška, Jan (advisor)
This bachelor thesis is focused on the design of a robotic welding cell, a clamping fixture for a given component and subsequent virtual commissioning of the workplace. In the theoretical part is examined a current knowledge of industrial automation and robotics, as well as MIG welding method. An analysis of the clamping fixture and workplace, and a summary of the main aspects for their design are carried out furthermore. In the practical part are designed 3D models based on the previous analysis. A control program is created for these models and the workplace is virtually commissioned.
Extruder design for special 3D printing
Šedý, Karel ; Vetiška, Jan (referee) ; Pavlík, Jan (advisor)
The bachelor thesis deals with a design and construction of an extruder for 3D printing of ceramic clay. The author aims to find a simple method of assembly and cleaning of the extruder. In the introduction of the bachelor thesis, the reader is briefly introduced to the history of 3D printing. Furthermore, the thesis examines 3D printing and ceramic clay, including its types, properties, and suitability for 3D printing. In the following chapters, possible problems with ceramic clay printing and how to avoid these problems are described. A multi-criteria analysis including key parameters and their weights was used to select a suitable design option. The final chapter provides a detailed description of the chosen variant's construction.
Logging station for humid environments
Pavlík, Jan ; Roubal, Zdeněk (referee) ; Szabó, Zoltán (advisor)
This thesis is about the design of a meteorological station deployed in a wet environment and its construction. The station will be used for measuring meteorological instrumentation in caves, because of that the station was designed to minimize its power consumption. Firmware was designed, to allow remote control of the station. A major part of the thesis is concerned with selection and description of the sensors and components used. Near the end of the thesis the control algorithm, communication interface and construction of the device is described.
