Reasons for low Linux adoption on desktop PCs
Langer, Filip ; Haupt, Jaromír (referee) ; Sedláček, Pavel (advisor)
Cílem této bakalářské práce je seznámit jejího čtenáře s operačními systémy Windows a Linux, jejich prostředím, programy, kterými disponují, jejími silnými a slabými stránkami a určit, proč je operační systém Linux málo adoptovaný mezi uživateli stolních počítačů. Tato semestrální práce by měla poskytnout jejímu čtenáři dostatek informací potřebných k určení, který z těchto operačních systémů bude více splňovat jejich potřeby. Rozhodnutí napsat semestrální práci na toto téma jsem udělal na základně vlastní zkušenosti, kdy jsem se jako uživatel potýkal s nedostatkem informačních materiálů na toto téma.

Technology of product machining on CNC machines
Brázda, Jiří ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
This diploma thesis deals with a technology of production milling of sample component “ending of generator shaft” by CNC milling in environment of small company. At first common aspects of CNC machines, technology of CNC milling and technology of construction are introduced. Possible problems with milling of sample component are analyzed and their possible solutions are presented. Next technology of CNC milling with operating program for CNC lathe (HAAS SL20) and CNC milling machine (HAAS VF3), production of component in small company with necessary documentation in technology procedure are projected. Using of operating systems HAAS, Fanuc and HEIDEHAIN are compared. Using of cutting tools and cutting condition for component milling is projected. Finally timing of operations and financial calculations necessary for small production of sample component is proposed.

Issue of Migrating from Single-Core to Multi-Core Implementation of Operating System
Skopal, Jakub ; Krčma, Martin (referee) ; Strnadel, Josef (advisor)
This thesis deals with the modifications of the hardware design and operating systems of the ZedBoard multi-core platform so that both ARM Cortex A9 processor cores included in SoC Zynq7000 can be used. It analyses the general issue of the multi-core environment and the core functions of the kernel and the operating system. It describes selected means of implementation ZedBoard and FreeRTOS. In the implementation section, specific steps are demonstrated to convert a single-core operating system to a multi-core system but also steps required to run two different operating systems on two processor cores. In the last section all achieved results are summarized.

Cyber attacks on operating systems
Holasová, Eva ; Komosný, Dan (referee) ; Člupek, Vlastimil (advisor)
This bachelor thesis is focused on cybernetic attacks towards operating systems. In the thesis, there are discussed base security functions of operating systems Windows, Linux and macOS; followed by described cybernetic attacks and its differences. The chapter Malware describes the most harmful software. Next chapter is about common awareness of cybernetic attacks, in which terms antivirus, firewall and IDS/IPS (Intrusion Detection System/Intrusion Prevention System) systems are defined. Following chapter brings scenario of ethics of hacking on operating system of personal computer, server and web server by using penetration tests. The thesis is finished by doing ethics hacking and evaluations. The goal of this thesis is to summarize the problem of cybernetic attacks, methods and tools whose goal is to break the security of the system, the use some of these method to do ethics hacking in virtualized environment.

Multimedia System for Support of Languages Education
Drápal, Libor ; Eysselt, Miloš (referee) ; Kreslíková, Jitka (advisor)
This project is about electronic learning (e-learning). The first part of this document explains the meaning of the term e-learning, where it is used and what advantages and disadvantages has this type of learning compared to the other methods of learning. The user gets familiar with tools that create the electronic lesson and how to design the lesson. In the second part there are described different techniques and tools to create application interface, to display 3D graphic and to play audio records in different operating systems. In this part, there are described tools in more detail for the operating system Microsoft Windows. The goal of this project is to design and to realize the multimedia system for language education. With the use of 3D graphic and audio records the educational system was created with sophisticated appearance and comfortable control.
