JamVM: An Alternative Java Virtual Machine
Kalman, Ondřej ; Kočí, Radek (referee) ; Dudka, Vendula (advisor)
This thesis deals with comparison of two virtual machines, namely HotSpot and JamVM. The first chapters of this thesis contain introduction to Java platform and summarize general properties and principals of Java virtual machine. The next chapters follow on this introduction and compare different properties of HotSpot and JamVM virtual machines. Based on these differences was designed and described set of benchmark tests which was also implemented and performed as practical part of this thesis. Last chapters deals with results of performed benchmark tests.

A Comparison of CACAO Virtual Machine and HotSpot JVM
Malík, Nikolaj ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
The aim of this thesis is introduction of Java platform and two chosen representants of Java Virtual Machine (JVM) implementations. At first JVM HotSpot as widespread one and on the other side JVM CACAO as an alternative option. This thesis describes implementation of chosen areas of both machines. It provides useful information for everybody who deals with runtime program optimalization. Final part presents benchmark results of the match between abovementioned machines by memory and time complexity.

Java Applications Monitoring Using JVM Tool Interface
Vomáčka, Pavel ; Dudka, Vendula (referee) ; Kočí, Radek (advisor)
This thesis deals with the design and implementation of an agent with a purpose to watch over the stack and over the heap with focus on localization of object allocation. This information is then shown in graphic user interface. A JVM TI interface is also described. Later parts of the thesis discuss the Java Virtual Machine and its important components with special attention to its memory management.

Jump server preparation and implementation for game scenarios in Cyber Arena
Komárek, Ladislav ; Šeda, Pavel (referee) ; Stodůlka, Tomáš (advisor)
Bachelor's thesis deals with the problematics of the containerization and virtualization. Thesis focuses on the OpenStack platform and the creation of a Jump server. The main purpose of the thesis is to create a Jump server with the SSH connection to the OpenStack instances. Thesis is divided into three parts - theoretical and practical, which has two parts. The analysis of virtualization and containerization possibilities for Jump server is included in the theoretical part of the paper. Description of the OpenStack platform and its functions is also contained in the theoretical part. Based on the theoretical analysis, a~Jump server was created in second and third part. After manually verifying the functionality of the Jump server, its creation was automated on the Openstack platform.

Application for illustrating the structure of the tested environment
Kuřina, Petr ; Holasová, Eva (referee) ; Kuchař, Karel (advisor)
This bachelor work deals with the creation of an application for the representation of the structures of the tested environment. The theoretical part describes the tools that are processed in the practical part, they are mainly the JavaScript programming language, Vue.js framework and penetration testing in general. The practical part presents the results of network topology testing was performed by Nmap tool. The aim of the practical part is to create an application that will clearly explain the results of testing to the user.

Visual Programming Backend for a Mobile Robot
Staněk, Ondřej ; Obdržálek, David (advisor) ; Bednárek, David (referee)
Title: Visual Programming Backend for a Mobile Robot Author: Bc. Ondřej Staněk Department: The Department of Software Engineering Supervisor: RNDr. David Obdržálek, Ph.D. Supervisor's e-mail address: David.Obdrzalek@mff.cuni.cz Abstract: In this work, the author designs and implements a solution for programming small mobile robots using a visual programming language. A suitable visual programming front-end is selected and back-end layers are created that allow execution of the program in a mobile robot. The author designs and implements a virtual machine that runs alongside the original robot firmware on an 8-bit microcontroller with limited resources. A code generator layer compiles the visual representation of the program into a sequence of bytecode instructions that is interpreted on board of the mobile robot. The solution supports typical features of procedural programming languages, in particular: variables, expressions, conditional statements, loops, static arrays, function calls and recursion. The emphasis is put on robustness of the implementation. To verify and maintain code quality, methods of automated software testing are used. Keywords: visual programming language, virtual machine, mobile robot, Blockly Powered by TCPDF (www.tcpdf.org)

Cybersecurity game in OpenStack platform
Huška, Luděk ; Lieskovan, Tomáš (referee) ; Stodůlka, Tomáš (advisor)
The bachelor thesis is about creation of the cybernetic game on the OpenStack platform. The work starts with an explanation of necessary knowledge like: Informational cybernetic and computer security, security threats, and testing of the overall security. In the practical part, there is created a cyber game that focus on exploitation and basic security vulnerabilities. The next part involves analysis ongoing complexity of hardware resources like RAM, CPU, disc, etc. In the end, there is a guideline for a lab exercise, which is made for students and professors or teachers both separated.
