Intelligent File Distribution in CDN
Kaleta, Marek ; Kouřil, Jan (referee) ; Škoda, Petr (advisor)
This work deals with algorithms for distributing and mapping content on nodes in CDN system. Compares local and global algorithms for loading files on origin and edge servers. A high level CDN simulator is made. A matrix based approach for mapping content on CDN servers is proposed along with tranformation for solution of mapping optimalisation through genetic algorithms.

Balancing turbines rotor
Peterka, Zdeněk ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
This bachelor’s thesis is specialized search dealing with issues of balancing turbines rotors. The first part of this work is devoted to general problems of balancing turbines rotors and basics of balancing turbines rotors. In the second part of this thesis there is a documentation of balancing device so-called „shelter“. The third part already discussed about the very processes of balancing turbines rotors. In the last part there two examples of practical balancing turbines rotors.

Possibilities of 2-cylinder Engine Balancing for Tractor Usage
Vaško, Roman ; Franz, Rudolf (referee) ; Dundálek, Radim (advisor)
This thesis deals with possibilities of 2-cylinder engine balancing for tractor usage. The purpose of this thesis is to find a technical solution for the creation of the concept of balancing using balancing shaft. Check the proposed solution by FEM analysis and evaluate the fatigue safety. The content of the thesis is the creation of computational and graphical documentation too.

Three cylinder diesel engine for commercial vehicles
Briš, Tomáš ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
The diploma thesis deals with a design of a crankshaft for a three-cylinder diesel engine for commercial vehicles. The engine is a member of a unified line of engines with the number of cylinders from two to six. The main points of the work are a draft of the crankshaft configuration, the balance of inertial forces and the moments in the crank mechanism, creation of drawings of the crankshaft and finally carrying out a strength analysis of the part, taking into account torsional vibration. The aim is formation of a part – crankshaft for potential usage in the automotive industry.

Six cylinder diesel engine for commercial vehicles
Pulava, Oleksandr ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
The aim of this diploma is to design a crankshaft for a six-cylinder commercial vehicle, which is one of the unified motors. The main parts are the design of the crankshaft configuration, the crankshaft balancing method for forces and moments, the crankshaft design documentation, and the crankshaft strength verification. The design of torsional vibration damping characteristics is also made and its effect on torsional vibration and crankshaft strength is determined.

Russian threat through the prism of British competitive liberalism
Samborskyi, Artem ; Riegl, Martin (advisor) ; Hynek, Nikola (referee)
1 CHARLES UNIVERSITY FACULTY OF SOCIAL SCIENCES Institute of Political Studies Department of Security Studies Master's Thesis 2023 Artem Samborskyi 2 CHARLES UNIVERSITY FACULTY OF SOCIAL SCIENCES Institute of Political Studies Department of Security Studies Russian threat through the prism of British competitive liberalism Master's thesis Author: Artem Samborskyi Study programme: International Security Studies Supervisor: doc. Martin Riegl, Ph.D. Year of the defence: 2023 3 Abstract The thesis is aimed at addressing the existing lack of academic understanding of the United Kingdom's foreign policy towards the Russian Federation, which stems from insufficient conceptualization of the current posture of Britain on the international stage and lack of in- depth research of the reasons behind the apparent animosity between London and Moscow. Specifically, the work answers the question of why the Russian Federation is designated the most acute direct threat to the United Kingdom and its "most urgent" foreign policy priority. The thesis is comprised of three major parts, each dedicated to a specific source of explanations of the mentioned research problem. Namely, the first two chapters constitute a document analysis of governmental, publicly available British thinking on the matter and academic literature...
