Cost analysis of passive houses and houses with zero energy demand
Gregovská, Kateřina ; Aigel, Petr (referee) ; Výskala, Miloslav (advisor)
The bachelor's thesis deals with the envelope structures of an existing family house, which is in a passive standard. The constructions being compared are therefore peripheral, floor and roof. The subject of this work is whether the proposed structure composition is effective, both in terms of heat transfer coefficient and in construction costs and speed. Alternatively, find a better possible variant of thermal insulation for already designed compositions of envelope structures. The work therefore compares different types and thicknesses of thermal insulation. The values of heat transfer coefficient, cost intensity and time intensity were used for comparison.

IoT Security
Hanzlíček, Martin ; Malina, Lukáš (referee) ; Hajný, Jan (advisor)
This work focuses on the problematic of the Android Wear platform security. The work solves the question of the time-consumption of calculations with big numbers, modular arithmetic and cryptography of this platform. Furthermore, solves the work the question of the communication with mobile devices and the authentication protocol client-server. The outputs of the work are three applications. The first application is suitable for Android Wear and it tests the time-consumption of particular calculations, communication with a mobile device and it also works as the issuer to the user registration and verification. The second application is for Android. The main function is the user registration and user’s authentication in cooperation with the application on the Android Wear platform and the computer application. The last application is suitable for computer and it works as the finisher of the registration and its authentication.

Economic analysis of machining process
Kalnaši, Radoslav ; Osička, Karel (referee) ; Prokop, Jaroslav (advisor)
This master’s thesis focuses on analysis of time consumption of machining process, the basic units of operating costs of production,optimization and subsequen tapplication to specific part. It is a turning shaft in two operations, named roughing and finishing turning. The aim is to find the optimum combination of life time of cutting tool and cutting speed, which is the main criterion for optimization in terms of minimum production cost or a maximum of productivity.

Hough Transform for Line Detection
Leikep, Bořek ; Beran, Vítězslav (referee) ; Španěl, Michal (advisor)
This paper is describing use of the Hough Transform for line detection. It also contains theoretical description of circle detection and detection of more complex subjects. The goal of this work is to evaluate implementation of line detection in C# on Microsoft .NET platform mostly from a time consumption point of view. The paper contains description of implementation of the application Detektor which is part of this work.

Cryptographic protocols for privacy protection
Hanzlíček, Martin ; Dzurenda, Petr (referee) ; Hajný, Jan (advisor)
This work focuses on cryptographic protocol with privacy protection. The work solves the question of the elliptic curves and use in cryptography in conjunction with authentication protocols. The outputs of the work are two applications. The first application serves as a user and will replace the ID card. The second application is authentication and serves as a user authentication terminal. Both applications are designed for the Android operating system. Applications are used to select user attributes, confirm registration, user verification and show the result of verification.

Security applications for Android
Celeng, Michal ; Burget, Radim (referee) ; Hajný, Jan (advisor)
The work deals with the issue of operations with large numbers in the enviroment of the Android operating system, mainly their time consumption and the implementation of protocol HM12 created for attribute authentication. The output of created application is a QR code generated with the necessary information for the user authentication. A premise is to preserve user's anonymity and other features expected in a modern cryptography.

Methods of Work Standardization as a Basis for Management of Production Processes
Vávrová, Monika ; Tesař, Rostislav (referee) ; Jurová, Marie (advisor)
In this diploma thesis, standards and norms for calculating time consumption in the company JULI Motorenwerk s.r.o., in Moravany near Brno, are developed. The aim of this work was to find out the state of current standards in the company and, if necessary, update them or create a new form for work standardization. The theoretical part describes the methods that can be used, either by direct or indirect measurement, for work standardization. The work also includes the development and introduction of the company. In the practical part, a proposal is created for work standardization using the selected method. Furthermore, individual tables are created both with the measured times and with the names and descriptions of the given operations, for clear standardization. The conclusion is an evaluation of the choice of methods for measuring standards and the creation of norms and the subsequent comparison of the resulting times with the times set in advance by the standards in the company.
