Analysis of dynamic properties of pneumatic actuator
Hrivňák, Ján ; Žatko, Miroslav (referee) ; Malenovský, Eduard (advisor)
This thesis deas with dynamic analysis of pneumatic actuator which is used as regulation mechanis of turbochargers with Variable Nozzle Turbine (VNT) technology. The first part of work is focused on experimental modeling which goal is obtaining Frequency Response Function on specify frequency range by Frequency Response Function Analysis – FRFA. Dominant vibrations of pneumatic actuator active parts is expected on this specify frequency range. Results of experimental modeling will be used for gaining input parameters for numerical computation as well. The second part deal with Pre-Stressed Modal Analysis and subsequently Harmonic analysis. Obtained results with numerical and experimental analysis will be compared. This part of diploma thesis is solved in programmatic environment ANSYS Workbench.

Interactive Form for Tax Returns
Hél, David ; Hrivňák, Ján (referee) ; Hynek, Jiří (advisor)
This bachelor's thesis deals with the design and development of a interactive forms for tax returns in the Czech Republic which are easy to fill in for every taxpayer. For tax returns, official web application is provided. This official app contains imperfections, which are analysed in this thesis. The main goal of this project is to develop simple yes/no forms which will guide users through the whole tax return. Based on user's answers, application generates form, which can be submitted at revenue authority. At the current stage, the application successfully generates the Personal Income Tax form. In the next phase, we expect the involving forms for other types of taxes.

Driving-School Quality Improvement Using User Experience Sharing
Hrivnák, Jan ; Burget, Radek (referee) ; Beran, Vítězslav (advisor)
This thesis analyzes the User Experience in design and development of new Web applications. Thesis describes the proper use of the UX methods and also deals with the possibility of using gamification in the design of new services. The work also contains analysis of the market of driving-schools in the Czech Republic and defines its main problems. Like a solution to these problems, the work includes the design and implementation of a new web application for sharing experiences among students.

Phishing Detection in Web Pages
Beňo, Marek ; Hrivňák, Ján (referee) ; Holkovič, Martin (advisor)
This work deals with the design of a phishing attack detection and classification tool. The work describes techniques and forms of phishing attacks and availible tools and techniques for phishing detection. Based on the analysis of existing tools a solution for file classification is proposed. Implemented tool handles input parsing and creation of input model. Model is based on hybrid analysis of input file and URL. Using the YARA tool, YARA rules are applied which are then used in creation of input classification. Analysis of input model and definition of classification rules is enabled by implemented YARA module. Implemented solution makes it possible to define YARA rules for phishing classification based on the structural properties of a phishing file and features of source URL.

System for Quality Control Management of Devices
Černý, Lukáš ; Hrivňák, Ján (referee) ; Hynek, Jiří (advisor)
This diploma thesis describes both the theoretical and practical part of the process of design and implementation of interactive computer software for the~management of~the~quality control of the~devices, assigned by SIGMA GROUP a.s., more precisely its Energo division, which is engaged in the maintenance and repair of pumping equipment. The theoretical part explains the concept of user experience, its acquisition methods, specification of~requirements and interface design methods. The next part is focused on the description of the~formats used by common text editors. Within the theoretical part is described the design of the interactive application itself. In the practical part there is a description of the main parts of the system and the conclusions from the system testing.

NoSQL: Support of Multidimensional Data Storage
Hrivnák, Jan ; Zendulka, Jaroslav (referee) ; Volf, Tomáš (advisor)
This bachelor's thesis deals with posibilities of storing multidimensional data in NoSQL databases. It compares suitability of several different databases for storing trajectories of moving 2D objects. Experiments with MongoDB were carried out to find the best way to store trajectories and create indexes over them. This thesis also provides a simple demonstration program in Python which works with MongoDB API.

Longitudinal log splitting in repairs of timber structures
Kloiber, Michal ; Hrivnák, Jaroslav ; Bryol, R. ; Tippner, J.
The range of technologies used has lacked a description of the traditional longitudinal log splitting, which was often used in order to utilize the maximum possible volume of timber extracted for constructions (especially rural timbered buildings). Longitudinal splitting supports carpentry sustainability as well as allows for accurate replication of the original elements (in dimension, shape, technology). Therefore, the research focused on the design of a procedure practically usable and applicable in the common practice for repairs of timber structures, especially historical monuments. Such a procedure is longitudinal splitting using wedges (metal and wooden) and mallets. The aim of the heritage conservation procedure was to practically describe the technical solution, the technological procedure of longitudinal log splitting allowing the use of hand tools only. The procedure respects the protection of cultural heritage standards, in particular the requirement to minimize interference with the original material, while retaining high accuracy of reproduction of the original properties of structural elements.
