Mathematical Methods of Image Segmentation for Remote Sensing Applications
Novotný, Jan ; Klimánek, Martin (referee) ; Štarha, Pavel (referee) ; Martišek, Dalibor (advisor)
Segmentation of an image into individual tree crowns is a key step in the processing of remotely sensed data for forestry practice. The doctoral thesis gives a broad overview of this topic. It comprehends theoretical context from mathematical point of view and defines basic terms from airborne imaging and laser scanning. Mathematical methods of tree detection are focused on a robust adaptation to the actual conditions in a region of interest. A novel approach of crown area delineation is introduced, it combines a seeded region growing technique with an active contour as a crown boundary representation. The parametrisation of all algorithms is analysed in a practical half of the thesis and more application-oriented issues are mentioned. Executable computer programs are attached.

Dimensioning of Supporting Constructions for MV Overhead Lines
Křepela, Pavel ; Novotný, Jan (referee) ; Orságová, Jaroslava (advisor)
The reason of supporting constructions is to transfer all power activity and fulfill all requirements on safe operation of electrical grid. This bachelor’s thesis deals with designing of supporting constructions of the overhead line MV. The main task is to acquire knowledges about single parts of supporting constructions and to describe steps of power effects calculation according to current legislation. The outcome is a simple software application for supporting constructions design from power effect viewpoint.

Draft block for dough processing
Novotný, Jan ; Vlašic, František (referee) ; Dvořáček, Jiří (advisor)
The Bachelor´s thesis deals with a structural design of a draft block of the placement of dough processing rollers, which are used for stiffening wheat dough in bakery lines intended for the production of common bakery products. The introduction gives a description of a bread and common bakery making production line. Next the thesis briefly deals with other possible dough-stiffening methods and with sanitary, structural and material requirements for food processing machinery. The structural part is devoted to a roller propulsion draft and a solution of a shift of one of the rollers. It contains a calculation of a worm gear, a load shaft calculation and a complete design documentary materials.

Design support for BricsCAD/AutoCAD
Hasal, Ondřej ; Bátora, Branislav (referee) ; Novotný, Jan (advisor)
This work deals with programing of a user interface in AutoCAD or BricsCAD which shall be used for drawing strong and weak current wiring in housing. I have used AutoCAD as the primary software and I have programed entire working menu in it. In BricsCAD I have programed sample menu to show how could we work with it and expand it. In the work I deal with change of design and properties of AutoCAD or BricsCAD. Part of the work deals with design and making of electrical symbols. I have dealt with how to use generated data without generating duplicates, when designing work environment in AutoCAD and BricsCAD. I also dealt with displaying and inserting of the created symbols into the drawings.

Testing of transformer protection
Kulač, Ivan ; Novotný, Jan (referee) ; Orságová, Jaroslava (advisor)
The main theme of my Bachelor thesis was protection of the transformer, measured case was orient to differential protection of the transformer, functions, stabilization and release characteristic. The proposed method of testing module SPCD3D53 differential protection SPAD 346C which was made by ABB. Setting of release characteristics on the protection were made for real power transformers. Testing device OMICRON CMC 256 plus was used to measurement, which was same as protection connected to personal computer. All the PC’s settings operations were realized by recommended software. The measurements were made for three cases, when differential current was in one, two or three phases. Results of measurement are mentioned in tables and graph.

Application of the PRINCE2 Methodology
Cagalová, Eva ; Novotný, Jan (referee) ; Juřica, Pavel (advisor)
The aim of this diploma thesis is to improve onboarding project management by identifying the differences between PRINCE2® methodology and existing transition process of the company. Found differences will be the baseline for new proposals that should make the project management more efficient by cost and time savings. These proposals are intended to rise the level of client‘s satisafacion, which would lead to the possibility of receiving higher volumes of new projects.

Absorption heat pumps for small applications
Pejcl, Jiří ; Novotný, Jan (referee) ; Mastný, Petr (advisor)
This bachelor work is focused on absorption heat pumps for small applications. The aim of this work is to compile the basic differences between compression heat pumps and absorption heat pums. And also to propose the system with absorption heat pump, which is energeticly classified in the end of the work. In the opening part there is the constructional description of these heat pumps, there are explained basic principles of these mechanisms. Then you will find the comparison of absorption heat pumps and compression heat pumps. Next fraction is concerned with design of the system with absorption heat pump. There is the system with absorption unit designed - this unit enables to heat and to cool. And also with solar system, which will support the heating process of supply water. Final part is applied to energetic evaluation of designed system, for purpose of this evaluation are made basic counts of required energy.

Electrical installations in apartment building
Novotný, Jan ; Formánek, Marian (referee) ; Doležalová, Jana (advisor)
This bachelor's thesis deals with electrical wiring in apartment building. The aim is to describe the types of distribution networks, implementation possibilities of service lines, describe the individual parts of the wiring in the building and the principles of their implementation. Further describe basic electrical materials and to explain the design of artificial lighting. In the practical part the information applied to a particular apartment building, together with the calculation of the estimated annual energy consumption of flats. For the apartment building project is created in the form of engineering report and drawings.
