Asymmetric Multiprocessing on the ARM Cortex-A9
Riša, Michal ; Košař, Vlastimil (referee) ; Korček, Pavol (advisor)
Asymmetric multiprocessing (AMP) is a way of distributing computer system load toheterogeneous hardware and software environment. This thesis describes the principles of the AMP focusing on the ARM Cortex--A9 processor and Altera Cyclone V hardware platform. Development of a OpenAMP framework based AMP system showing communication among the processor cores, documentation and future work suggestion are the products of this thesis.

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.

DotVVM to Accelerated Mobile Pages Transpiler
Tichý, Michal ; Polčák, Libor (referee) ; Pluskal, Jan (advisor)
This thesis proposes an extension to the DotVVM web framework that adds support for conversion of DotVVM pages into AMP pages. This thesis describes the current status and inner workings of DotVVM and AMP. The thesis contains an overview of the advantages and disadvantages of both technologies. Second part of this thesis describes implementation of DotVVM.AMP. Final part of this thesis shows integration of DotVVM.AMP into an existing DotVVM application.

Design and construction of a tube guitar amplifier
Šona, Štěpán ; Dvořák, Jan (referee) ; Kubánek, David (advisor)
The text of this bachelor’s thesis deals with the design, simulation and construction of a tube amplifier for electric guitar, based on the well-known guitar amplifier VOX AC 30. The theoretical part deals with the design and simulation of the original circuit. Subsequently, adjustments were made on both channels and simulated. The practical part of the work already deals with the construction itself, measuring the finished guitar combo. Frequency modulus characteristics, harmonic distortion, spectra and time courses of signals for distorted and clear channel were measured. Then the measurement was evaluated.

Accelerated Mobile Websites Using AMP HTML and AMP JS
MAYER, Martin
The objective of the bachelor thesis will be develop and describe AMP (Accelerated Mobile Pages) technology. AMP is a technology invented by Google and it is designed to quickly load static content mostly on mobile devices. The advantage of this technology is a very simple HTML structure with minimal use of tags and fast loading thanks to Google AMP Cache, which loads HTML, JavaScript and images into its own cache. As a disadvantage, I would see a relatively small maximum CSS size and that you can not use almost any custom JavaScript. In the theoretical part I will focus on the introduction of the AMP technology itself, its syntax, functions, describtion of the individual AMP components, comparison with classical HTML and describtion of the advantages and disadvantages of this technology in creating websites. In the practical part I will create a website using AMP technology, which will be used to demonstrate the possibilities of this technology. I will also create a survey where I will compare websites created by AMP and websites created by classic HTML for Czech and foreign websites.

Extraction of nucleotides from plant matrix and their determination by ion-exchange high performance liquid chromatography
Konečná, Markéta ; Sobotníková, Jana (advisor) ; Coufal, Pavel (referee)
In this thesis chromatographic conditions for the HPLC analysis of ribonucleotides AMP, ADP and ATP were optimized. For their separation chromatographic column, Nucleogel SAX 1000-8, 50 x 4,6 mm, from the German company Marcherey-Nagel was used. The mobile phase of a 0,2 mol/L solution of KH2PO4, its pH was adjusted with 1mol/L with potassium hydroxide to pH = 5,00. As the most suitable flow rate was selected 1,0 mL/min. The analysis was conducted using an isocratic elution. Detection was conducted by a DAD detector at a wavelength of λ = 260 nm. Substances were eluted in the following order AMP (tr = 0,911 min), ADP (tr = 1,667 min) and ATP (tr = 7,262 min). The total analysis time of the mixture of standards, under the conditions mentioned above, lasted for 10 minutes. For the extraction of adenosine-5-ribonucloetides the real matrix frozen and lyophilized leaves of tobacco virginia (Nicotiana tabacum L.) have been used. Two methods of extraction were applied. The first procedure was based on the extraction of AMP, ADP and ATP from the leaves of the tobacco plant by boiling deionized water. In the second method 0,07 mol/L HClO4 for the extraction instead of deionized water was used. Keywords: HPLC, adenosine ribonucleotides, AMP, ADP, ATP, tobacco virginia
