Acceleration of Open vSwitch in DPDK
Vodák, David ; Kučera, Jan (referee) ; Martínek, Tomáš (advisor)
Virtual switch is a software that connects virtual machines to the internet, which makes it a crucial part of virtualization on servers. Nevertheless, it can be rather ineffective when it comes to high speed traffic, since it switches all frames in the software. This thesis is about hardware acceleration of the virtual switch called Open vSwitch. The acceleration prototype, which is the goal of this thesis, is based on the RTE flow interface, the SR-IOV standard, and Intel PAC N3000 card. In the scope of this master's thesis, all necessary technologies were described and the acceleration prototype was designed, implemented, and tested. Results of executed measurements indicate increased throughput when rules of the acceleration prototype were offloaded to hardware.
Parsing Based on Regulated Grammars
Vaníček, Luboš ; Kučera, Jiří (referee) ; Meduna, Alexandr (advisor)
This thesis deals with regulated grammars. It describes their behavior and it compares them using different examples of context-sensitive languages. The thesis focuses mostly on programmed grammars. It modifies the methods of parsing and it uses them for programmed grammars. This thesis applies the developed method of parsing on context-sensitive languages and examines their power.
DEFORMATION BEHAVIOR OF NANO/MICRO REINFORCED PMMA
Recman, Lukáš ; Nezbedová, Eva (referee) ; Kučera, Jaroslav (referee) ; Jančář, Josef (advisor)
Práce sleduje vliv velikosti částic na elastický modul a deformační chování za mezí kluzu. Bylo pozorováno, že jak elastická oblast, tak oblast za mezí kluzu ukazuje silnou závislost chování na velikosti částic. Cílem této práce je korelovat experimentální data a teoretické předpoklady které bylo odvozeny pro deformační chování v elastické oblasti a v oblasti za mezí kluzu pro amorfní polymery a konkrétně pro PMMA. Vše je motivováno propojit zatím oddělené oblasti kontinuální mikromechaniky a diskrétní nanomechaniky. Deformační chovaní PMMA plněného nano a mikro plnivem bylo pozorováno v elastické a plastické oblasti. Byl zkoumán vliv velikosti částic na velikost modulu a deformačního zpevnění. Mechanizmus vyztužení je interpretován s použitím teorie imobilizace řetězců, nanočástice mají silný vliv na molekulární dynamiku a kinetiku zapletenin. Mým příspěvkem k tomuto tématu je ukázat výraznou závislost na mechanizmu vyztužení v závislosti na velikosti částic. A to jak pod teplotou skelného přechodu tak nad teplotou skelného přechodu. Ačkoli pro velikost modulu byla publikována značná množství dat, která byla následně i interpretována, vliv částic na deformační zpevnění je poskrovnu. Během elastické deformace je primární struktura materiálu neměnná, jedná se o elastickou deformaci, za mezí kluzu již toto neplatí a primární struktura je zde nevratně poškozena. Bylo ukázáno, že obsah nano částic vede ke zvýšení meze kluzu a vyššímu deformačnímu zpevnění. Tento nárůst deformačního zpevnění je v korelaci s Guth-Gold rovnicí. Je předpokládáno, že nanočástice slouží jako další fyzikální zapleteniny a vedou k fyzikálně více zapletenému systému. Stejný efekt jako v elastické oblast tj. vliv velikosti částic na modul, byla pozorována i během deformačního zpevnění.
Two-Dimentional finite automata and their applications
Hladík, Zdeněk ; Kučera, Jiří (referee) ; Meduna, Alexandr (advisor)
This paper introduces the theory of twodimensional languages automata in comparision to the classic concept of languages and automata. This theory is used for developing special automata, that is capable of analyzing tables containing rules. These tables are conected with rules for selected european car license plates. Automata and tables are used by developed application, which can be used for car nationality identification.
Libyang - Python 3 Module
Sedlák, David ; Kocnová, Jitka (referee) ; Kučera, Jan (advisor)
This bachelor thesis deals with interaction  between C and Python 3 languages. The main goal was to provide user friendly Python 3 binding for libyang2 library which provides interface for C language. Final Python 3 interface is created with help of CFFI package,  is simply usable in Python 3 and adequately uses rich features of Python 3 language. Comparison of few approaches and tools to interact with C library from Python code is also covered in the thesis, including measurements of call overhead caused by them. Implemented Python 3 interface will help with integration of YANG modeling language in network applications and devices.
Proposal for Ensuring Financial Stability of A Company
Kučera, Jan ; Tregler, Jiří (referee) ; Zinecker, Marek (advisor)
Goal of this master‘s thesis is to evaluate financial stability of company MOTORTEC spol. s r.o. by using financial analysis methods and to form proposals of solution in problematic sections.
Physical ageing of polypropylene
Weiss, Jiří ; Kučera, Jaroslav (referee) ; Tocháček, Jiří (advisor)
Physical aging of commercially produced polypropylene homopolymers Mosten was studied. The work is focused on monitoring the changes in physical properties of polymer in the time period 90 days from the date of preparation of the test specimen. The aging of polymers was realized at storage temperatures of 23 and 80 °C. The changes in crystallinity, yield strength, modulus, elongation and impact strength using DSC method, tensile tests and impact tests according to Charpy were monitored. Molecular weight distribution was determined by means of GPC at each polymer. Relationships between the changes in physical properties and polymer molecular weight were sought.
High-lift truck-types of drive
Kučera, Jonáš ; Škopán, Miroslav (referee) ; Špička, Jiří (advisor)
This bachelor thesis deals with drives of High– lift trucks, types of drives and basic description. It also includes confrontation of some parameters of single drives.
Employee Attendance System
Bartošek, Jan ; Kučera, Jan (referee) ; Kocnová, Jitka (advisor)
This bachelor's thesis concerns to design and implementation of a time and attendancesystem to track the employees in the company. In the first part defines what does a timeand attendance system mean and presents both statistics data and existing systems. In thenext part aims on designing such a software able to track employees, manage vacation andexport records. Continues with a list of used technologies and implementation of the systemitself. At the end the proccess and results of testing the system are described.
