Social Network Analysis and Simulations
Vorlová, Pavla ; Král, Jiří (referee) ; Samek, Jan (advisor)
This diploma thesis is focusing on description of processing social network analysis, design and implementation of a model that simulates a particular social network and its analysis. Social networks are modern and very used in this time. They are very good point for exploring. This project deal with static analysis social network, where social network is constructed by graph. We nd out di erent properties of single component and than we establish signi cance of them. Relationships between components are important too for us, because they have a big influence on propagation information in network. Structural properties figure out existence of di fferent communities. We simulate social network with multi-agent systems, they are desirable for represent changes in network. Multi-agent systems have implemented a simulation model that represents a particular social network. His behaviour was analyzed and examinated by chosen methods.

Dynamic Analysis of Selected Firing Mechanisms of Firearms
Mešina, Matej ; Hadaš, Zdeněk (referee) ; Slažanský, Martin (advisor)
This bachelor thesis strives to evaluate the dynamic analysis of firing mechanisms of different types of firearms. In the present research is analyzed the matter of firearms and ammunitions, followed by the description of distribution of firearm mechanisms, as well as the detailed scrutiny of the initiation mechanism. The thesis also marginally explores the testing of primers. The last part of the research documents the possible solutions for the analyzed issues. The practical part of the thesis is devoted to the geometry of firing mechanisms, followed by the description of the physical principles, which are relevant to this matter. Based on the analysis, a theoretical calculation of the initiation energies for all of the analyzed types of firearms is established. Lastly, the calculation of the initiation energy is calculated, and the security in secure firing of the bullet's primer is determined.

Dynamic analysis of railway bridge
Mojrová, Martina ; Vlk, Zbyněk (referee) ; Nevařil, Aleš (advisor)
The content of work is to determine modal characteristics of bridge construction over the Dyje river near Břeclav. That is done in ANSYS software and AxisVM software. These characteristics are compared with results from dynamic loading test and they are compared between themselves. In thesis is also an assessment of response to static traffic loads because of decision about dynamic analysis necessity. Then there is a simulation of dynamic traffic loads and results of this simulation are compared with results of dynamic analysis which was done by the project. The aim is to do a few static and dynamic tasks and compare results with the real dynamic test and with calculated results and to determinate the effect on certain variables.

Multiplatform Linux Sandbox for Analyzing IoT Malware
Uhříček, Daniel ; Burget, Radek (referee) ; Kolář, Dušan (advisor)
Analýza IoT malwaru je problematická zejména pro množství a rozlišnost architektur procesorů používaných IoT zařízeními. Práce shrnuje možnosti statické, dynamické a síťové analýzy Linuxového malwaru a hodnotí existující open source řešení oddělených běhových prostředí pro automatizovanou analýzu. Práce navrhuje modulární, rozšířitelný systém s~jednoduchými možnostmi nasazení, dostupnou API a webovým rozhraním. Výsledná implementace podporuje pět architektur a byla testována na vzorcích IoT malwaru.

Dynamic analysis of oscillations with multiple degrees of freedom
Schulmeister, Jiří ; Houfek, Lubomír (referee) ; Březina, Lukáš (advisor)
This thesis is dealing with analysis of oscillating with multiple degrees of freedom and with example of dynamic behavior of system with two degrees of freedom with different input signals for purposes of dynamic lessons. Conventional method of making equations of motion by Lagrange’s method and their consecutive analysis is inscribed in the work. As example of system with two degrees of freedom is chosen quarter car model. Responses to different input signals are shown for the model. It is made in MATLAB/SIMULINK.

Dynamic Data Race Detection and Self-Healing in Java Programs
Letko, Zdeněk ; Kolář, Dušan (referee) ; Vojnar, Tomáš (advisor)
Finding concurrency bugs in complex software is difficult. As a contribution to coping with this problem the thesis proposes an architecture for a fully automated dynamic detection and healing of data races and atomicity violations in Java. Two distinct algorithms for detecting of data races are presented. One of them is a novel algorithm called AtomRace which detects data races as a special case of atomicity violations. The healing is based on suppressing a recurrence of the detected problem and can be performed by introducing an additional synchronization or by legally influencing the Java scheduler. Basically forces certain parts of the code to be executed atomically. The proposed architecture uses bytecode instrumentation to be able to track and influence the execution. The architecture and algorithms were implemented and tested on multiple case studies.

Piston for SI Turbocharged Engine 2.0L
Kusyn, Petr ; Bradávka, Marek (referee) ; Svída, David (advisor)
This diploma thesis is focused on solve of design solutions for piston for turbocharged version of Honda K20A engine, especially on reduce of side force acting on piston. There are mentioned methods and on their basis also design solutions for piston to reduce this force. There is also included kinematic and dynamic analysis for each solution and as well their FEM analysis for testing the suitability of these solutions.

Simulation of the 5th car door mechanism
Taušek, Martin ; Škoda, Jan (referee) ; Hadaš, Zdeněk (advisor)
This bachelor thesis deals with simulation of the 5th car door mechanism. The simulation runs in MSC.ADAMS software in which was made simulation model. The model contains several bodies which needed to have the same mechanical parameters as the CAD model of the real 5th door so the simulation was accurate. The opening of door is done by two gas springs, one on each side. These gas springs had to be correctly dimensioned to achieve fully opened door and safety movement as well. The thesis also deals with kinematic and dynamic analysis of the mechanism.
