Optimalization of Induction Furnace Operation in foundry Vsetín
Trachta, Jiří ; Nowak, Stanislav (referee) ; Lázničková, Ilona (advisor)
The aim of this work is optimalisation of induction furnace in foundry for company PROMET FOUNDRY a.s. The company has two induction furnances. There are installed as identical construction. They have 2 modes of operation. First mode is founding and second mode is mode, where is temperature in maintain mode. Only one induction furnance can work in the founding mode at a time though. Inducion furnances are in the single-phase connection and they cause unbalance in the distribution network. Near the foundry there is a small network area whitch it is operated by company Zásobování teplem Vsetín a.s. The consumption of electrical energy in foundry so big, that in the year 2009 was made elaborate for Zásobování teplem Vsetín a.s. It was write at Laboratoře diagnostiky výkonů (Laboratory of performance diagnostics), which is a part of Electrotechnic Department at Technical Univarsity of Ostrava. The ordered study was named “Verification of causes of increased reactive energy consumption during transition from electricity delivery to electricity consumption”. The conclusion of this assignment confirms that in distribution network in the Jiráskova area in Vsetín there is unbalance of electrical energy and there is high part of reactive power. The next conclusion is crucial to find the customer who made the unbalance and to set relevant remedy. The last step will be the identification whether such device can actually be effectively balanced. It was subsequently proved that the Promet Foundry was causing the unbalance and that balanced consumption would be reasonable. Promet Foundry thus addressed Autel a.s. company with an inquiry to make a study of removing the causes of the unbalance which is caused by current induction furnaces operation at a minimum possible cost, least possible influence on the performance and minimum construction changes concerning the building. In this thesis there will be some topics. The result of which will be introducing of used heating technology, introducing of company and of effective plant performance and subsequent suggestions of possible unbalance removal or reactive power decrease. Several ways which are being implemented in the industry in order to balance consumption will be described. A suitable balancing plant will be subsequently chosen and its parameters will be calculated.

Implementation of HTML5 and CSS3
Míka, Jan ; Vondra, Zdeněk (advisor) ; Machek, Ondřej (referee)
This bachelor thesis is focused on testing and analysing HTML5 and CSS3. These programming languages are two most common languages for webdesign and webdeveloping. Theory part of this thesis introduces topic about the historical and current language specification. This part also explains role of CSS3 in conjuction with HTML5. In the main part, author defines common problems in coding, which are used for questionnaire research after that. The questionnaire itself is then created in the practical part. Questionnaire will be used for hypothes testing of statistic influence of defined measures. After that, ten elements will be chosen, which will be analysed and tested. At the end, the author measures advantages and disadvantage in using specific elements of these specifications.

Main causes of change requirements during web-based projects
Nagy, Jan ; Chocholatý, Drahomír (advisor) ; Kružík, Martin (referee)
This thesis deals with identification and analysis of causes of change requirements during web-based projects. The theoretical part of the thesis concentrates on an analysis of web-based project's specifics. In the following practical part of the thesis all of the identified causes of change requirements were aggregated together. Internet survey was performed with purpose to confirm identified causes in a literature and to enlarge the list of the caus-es. Every cause is described, analyzed and evaluated according to its criticality. Causal causes are determined by using convenient methods. In last chapter, a set of recommenda-tions for web developers (suppliers) are suggested based on the facts known from previous parts of the thesis. It is a list of best-practices for lowering a risk of change requirements occurrence and for minimalizing their impact on a project and also on social relationships between suppliers and customers. An existing literature generally considers change requirements just as one of many reasons of project's failure, however it does not focus satisfactorily on a research of their causes. Significance of the thesis is therefore based on its focusing on one specific area. The thesis provides a systematic summary of information, which serves for web project suppliers as an inspiration for an implementation intern process of specifying new project.

Software requirements in banking
Janoušková, Irena ; Pavlíčková, Jarmila (advisor) ; Maryška, Miloš (referee)
This diploma thesis deals with the areas of requirements management in large organizations, especially banks. Bank projects have their own characteristics, as well as the banking environment as such. The paper will analyze the problem of requirements management in general and during description of best practices and methodological procedures attention will be drawn to the peculiar characteristics of the banking environment. This thesis focuses mainly on methodological and personal aspects of requirements management - the role of the analyst and the requirements management methodology. One of the main goals is selection of requiremets management methodology suitable for use in banks. Other important objectives are the description of best practices and mapping of the description of requirements management in the most widely used software development methodologies. The paper can serve as a textbook for junior analysts and other team members, or as a reference guide. Well-educated analyst and knowledgeable project team members enhance probability of a successful completion of the project and objectives achievement within set deadlines, budget and to everyone's satisfaction.

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.

Role regionálních specifik západní Afriky v proměnách rozvojových koncepcí
Schreiberová, Rut ; Macháčková, Jaroslava (advisor) ; Trhlínova, Zuzana (referee)
Diplomová práce mapuje vybrané rozvojové koncepce regionu západní Afriky, identifikuje jejich charakteristické rysy a analyzuje jejich dopady s ohledem na kulturní specifika regionu a tím i jejich kapacitu odrážet skutečné potřeby jeho obyvatel. Posuzuje, do jaké míry byl při vypracování jednotlivých koncepcí brán ohled na roli kultury a jak tento faktor ovlivnil jejich úspěšnost. Klíčovou otázkou je, zda v regionu existují takové síly, které se zasazují o uchování jeho kulturní autonomie a pokud ano, zda mají samy o sobě rozvojový potenciál.
