Injection System with Pressure Accumulator for Vehicles of NRMM Category
Pavlík, Martin ; Prokop, Aleš (referee) ; Dundálek, Radim (advisor)
This bachelor thesis deals with the common-rail system in NRMM diesel engines and its application mainly in tractors. In the research part of the thesis is given a division of the system, a description of used components with an explanation of their function and furthermore examples of the manufacturing companies of these components. The second part of the thesis focuses on the components currently used in designs of fuel systems for specific machines. The parts of the tractors fuel system are presented in the thesis. Injection pressures were measured from data of sensor located on the high-pressure rail. The final part of the thesis focuses on produced pollutants while combustion process, the Stage V emission standard, emission reduction methods and the effect of alternative propulsion on the NRMM.
Entwicklung eines Wälzsstoßaggregates zur Erzeugung von Gerad- und Schrägverzahnungen auf flexiblen Bearbeitungszentren
Pavlík, Martin ; Hänel, Thomas (referee) ; Blecha, Petr (advisor)
Diplomová práce představuje návrh agregátu, který umožní rozšíření obráběcího centra o technologii obrážení ozubení odvalovacím způsobem. Principem této jednotky je, převést rotační pohyb vřetene na translační pohyb potřebný pro obrážení při současném dodání odvalovacího pohybu nástroje. Mechanismu zároveň zajišťuje konstantní řeznou rychlost, čímž zvyšuje životnost nástrojů. Jednotka je rozdělena na 5 dílčích mechanismů. U každého z mecha- nismů je analýzou použitelných metod vybrána nejvhodnější varianta. Ta je následně navrh- nuta a případně propočítána. V práci je popsán návrh takového řešení pomocí mechanických převodů a vaček. Tento mechanismus umožňuje obrážení při rychlosti 900 dvojzdvihů/min. při maximální vyvinuté síle 5,5kN. Jednotka je primárně určena pro malovýrobu, jako levnější alternativu k nákupu stroje pro obrážení.
Mirroring of Motifs of F. Nietzsche's Critique of Christianity in D. Bonhoeffer's Prison Theology
Pavlík, Martin ; Vogel, Jiří (advisor) ; Kučera, Zdeněk (referee)
The thesis "Mirroring of Motives of F. Nietzsche's Critique of Christianity in D. Bonhoeffer's Prison Theology" contemplates Bonhoeffer's thoughts on non-religious interpretation, that Bonhoeffer expands upon in his letters from prison, in the light of critique of Christianity that was expressed by Friedrich Nietzsche. Chapter I looks into the history of interpretation of Bonhoeffer's research and provides a brief overview of past and contemporary efforts to explain Bonhoeffer's approach to philosophy. Chapter II introduces basic principles and key topics of the critique of Christianity first in Nietzsche's work The Antichrist, followed by Bonhoeffer's Letters and Papers from Prison. Chapter III compares the most obvious motives in the thinking of Nietzsche and Bonhoeffer within the aforementioned scope. Selected themes in works of these two German thinkers overlap particularly in their philosophy of life, understanding of a man come of age, and their critiques of Christianity that is deflecting from this world towards the transcendent sphere of the world beyond (in German, it is expressed as a difference in the meaning of "Diesseits" and "Jenseits"). Bonhoeffer's thoughts on the preaching of Gospel to the man come of age who is free of false, religious misbeliefs, and who feels strong, capable,...
Extension of the 3D printers with head changer
Pavlík, Martin ; Tůma, Jiří (referee) ; Bradáč, František (advisor)
This work deals with a constructive solution of printheads exchange system on 3D printer. For keeping a RepRap-type printers concept, using as much 3D-printable parts as possible is emphasized. The system has solenoid-based exchange mechanism.
Password deposition techniques in operating systems
Pavlík, Martin ; Růčka, Lukáš (referee) ; Hajný, Jan (advisor)
This master thesis deals with ways to store passwords in current operating systems. Specifically, this work focuses on Windows, Linux, BSD and OS X. These systems are examined for ways of hashing passwords and on resistance of resulting hashes against various attacks. First (theoretical) section describes the procedures and algorithms that are needed for user authentication. This part also describes methods of hash storing. At the end of the theoretical part are generally described some possible attacks against hash functions. In second (practical) part is described and tested tools for obtaining hashes of the investigated operating systems. Subsequently practical attacks were conducted against obtained hashes by using appropriate tools. Furthermore there are presented results of the attacks. In the conclusion of the work there is a comparison of tools and methods which were used to obtain plaintext passwords from operating systems.
Fotogenerace nosičů náboje v polymerních nanokompozitech
Pfleger, Jiří ; Pavlík, Martin ; Vohlídal, J.
Polymer nanocomposites seem to be promising systems for solar cell application with polythiophene acting as photosensitizer and charge transport medium. The electrophoretic deposition proved to be suitable method for preparation nanostructured core/shell functional layers. The simplicity, fast operation rate and the possibility of covering surfaces of irregular shape, as well as a good quality of prepared films are the major advantages of the method.
Fotoelektricky aktivní polymerní nanokompozity
Pfleger, Jiří ; Pavlík, Martin ; Plieth, W. ; Vohlídal, J.
We established a new electrophoretic deposition method for the fabrication of photoelectrically sensitive structures, in which the core/shell nanoparticles dispersed in an organic solvent are deposited on a semitransparent conductive substrate under an external electric field.
