Modern methods of monitoring the degradation of insulation systeme of power plant large rotating machines
DVOŘÁK, Martin
Prediction diversification disturbances timely diagnosed booming disturbances insulative system big synchronous generator, working like significant source electricity supply system in zone base load boiler. Lessen risk machine fault is based on completion on - line system, following insulative system generator. On the grounds of dates obtained from on-line monitoring will possible to diagnose rising bug on all beginning their development yet before it, than in character grow turn-to-turn fault stator winding or cut off in magnetic circuit machinery. To following state insulative system machinery in those work I prefer using two independent on - line diagnostic methods, following state insulative system in the working condition machinery. Further in those work set up outlines technical solving for personal modernizing arrangement.

Tvorba mikro a nanoporů v polovodičích A.sup.3./sup. B.sup.5./sup
Nohavica, Dušan ; Gladkov, Petar ; Zelinka, Jiří ; Dvořák, Martin ; Pirov, J.
Electrochemically etched pores are accessible also in A.sup.3./sup. B.sup.5./sup. semiconductors. In particular, pores in InP, GaAs and GaP have been investigated in our laboratory. More complex experimental data have been collected for InP which is suitable for the preparation almost self organized pores net. Pores multilayer containing current oriented and/or crystallographic pores was prepared and some details of the process are discussed. The GaAs and GaP demonstrate both, current oriented and crystallographic pores as well with specific differences.

Zabezpečení malých internetových obchodů
Kohout, Karel ; Veber, Jaromír (advisor) ; Dvořák, Martin (referee)
The thesis describes selected security issues affecting small business e-commerce sites in the European Union and also shows whether such issues exist in authentic applications currently being used by means of a small scale study. It presents several specifics of e-commerce, a summary of European Union (European Community) law with focus on private data protection and unsolicited mail based on literature search and an overview of minimum security requirements for web-based applications. The research part contains an assessment of parts of a source code, documentation, incident response procedures and installation scripts of seven most popular PHP open-source shopping carts with regard to security derived from criteria and directives defined in the theoretical part. A limited field study of possible effects of security (or of lack thereof) on turnover is conducted and results are available at the end of the thesis.

ITIL in small and medium business
Pelcman, Jan ; Říhová, Zora (advisor) ; Dvořák, Martin (referee)
Presented thesis aims at possibilities of implementation of the ITIL best practice at small and medium businesses. The main target is to prove that this methodology can be used not only in big companies, but also in small and medium business sector. First part defines the conception of small and medium business and its specificity. It is concerned with basic definitions, which are used in the main text, such as a service, process, best practice etc. It also demostrates the need of managing IT and some ways how to do it. The second part dwell on ITIL itself, it describes its characteristics, history, it also discusses purpose and content of each ITIL book with emphasis on service operation books. The third part is about deployment of ITIL in SMB, conditions and process of implementation and it proposes some essential processes for small and medium business IT. Also it defines benefits of deployment of ITIL, its limitations and barriers. The final part is concerned about Incident Management implementation in a particular company, it describes the state before and after the implementation. It describes software support tool for this process, its possibilities and costs. At the end of this part an employee survey demonstrates the benefits of the Incident Management process and the SW support tool. It shows resulting improvement of IT support perception among the management and employees of the company.

XML specification proposal of electronically signed documents with timestamp.
Dvořák, Martin ; Svatá, Vlasta (advisor) ; Dostálek, Libor (referee)
Cílem diplomové práce bylo vypracovat návrh XML specifikace elektronicky podepsané zdravotnické dokumentace s časovým razítkem. V úvodu práce jsou definovány základní pojmy a principy digitálního podpisu. Následující kapitola obsahuje popis klasického obecného archivu. Archiv zdravotnické dokumentace se však od toho klasického liší. Dokumenty nejsou archivovány natrvalo avšak pouze po dobu specifikovanou legislativou. To je základní specifikum. Zdravotnická dokumentace má však další specifika, ze kterých je nutné vycházet. Dokumenty budou do archivační skupiny neustále přibývat, bude proměnlivá doba archivace zdravotnické dokumentace v závislosti na událostech v pacientově životě a dalším problémem je i fakt, že neexistuje závazná specifikace formální podoby zdravotnické dokumentace. Navrhovaná XML specifikace vychází z rozšířené základní syntaxe XML podpisu o elementy pro oblast archivace (XAdES-A) a ze specifikace základních metadat popsané ve standardu Dublin Core. Specifikace byla tvořena s cílem maximální univerzálnosti pro použití v oblasti zdravotnictví.

Small business computer security
Dvořák, Martin ; Doucek, Petr (advisor) ; Bébr, Richard (referee)
Tato bakalářská práce pojednává o stále aktuálnější problematice bezpečnosti informačních technologií. Cílem je provést analýzu hrozeb a rizik, které jsou pro podnikové sítě v současnosti nejvíce nebezpečné. Proto je práce zaměřena především na spam. Možnosti obrany proti spamu a nastavení podnikové sítě je ukázáno na zvolené malé firmě Orbisvideo. Na základě jednoduchého testu je prokázáno, že pouze technologie nestačí k zabezpečení počítače, ale je nutné aby samotní uživatelé dodržovali etiku chování na internetu.
