Modern methods for Chip Attach
Nešpor, Dušan ; Novotný, Marek (referee) ; Szendiuch, Ivan (advisor)
The work deals with packaging and die attach issues. The general aim of this investigation is thermomechanical stress between package and substrate depending on different thermal and mechanical properties of used materials. Work contains modeling with program ANSYS and practical tests with testing packages. Determining a place in the solder with the maximal and the minimal stress values and determining of the stress distribution for all materials are the results of this research.

Application of laser processes in crystalline silicon solar cells fabrication
Grob, Filip ; Novotný, Marek (referee) ; Hladík, Jiří (advisor)
This work is focused on the use of laser's process in the solar cells fabrication. The first part of Bachelor's work generally handles the theory in the field of the photovoltaic devices and the applications of lasers. In the second practical part of the work are recorded and evaluated the measurements to verify the use of laser to selective doping of N+ layer. There were also investigated applicability the laser for buried contacts fabrication and solar cells edge isolation.

Lycium chinense and Lepidium meyenii in new food products
Novotný, Marek ; Vítová, Eva (referee) ; Vespalcová, Milena (advisor)
This diploma thesis deals with application of wolfberry (Lycium chinense) and maca (Lepidium meyenii) in food products. Both plants have high nutrition content and are studied for their health benefits to humans. In case of wolfberry it’s mainly immune-stimulating and antioxidant properties. Maca is known for increasing fertility and there’s also reported lowering of cholesterol and blood sugar. In theoretic part are summarized findings about chemical composition, science studies about effects of these plants, situation on the Czech trade and project of use. Aim of this thesis was to create practical demonstration of use and consumption both plants and to evaluate it by methods of sensory analysis. For this purpose three samples of wolfberry cereal bars and three samples of chocolate with maca powder were produced. These samples were sensory evaluated using ranking test, scale test and profile test. Higher amount of maca in chocolate had worse rating, while use of wolfberry was rated quite well. Therefore three wolfberry cereal bars were produced as the final product in cooperation with bakery and chocolate factory Fikar – bar with fruit filling glazed with chocolate, classical bar glazed and classical bar not glazed with chocolate, as a demonstration of possible industrial use.

Excercises for Data Acquisition for BEMS course
Novotný, Marek ; Richter, Miloslav (referee) ; Čejka, Miloslav (advisor)
The content of this thesis is to understand a field of data acquisition. There is explained what it is data acquisition and also there are described frequently used terms and principles, which belong to this theme. We have to understand how to get useful information from a specific physical effect or event; how can be this information processed or represented. A part of this thesis describes hardware side of this mechanism – the most used buses and measuring systems, cards and modules belonging to it. There are also described used developing and measuring programmes, their features and system of output of applications besides. In the thesis we can see which tasks can use data acquisition, which problems can appear and we have to know about them. As an example of the whole data acquisition there are showed two tasks which are worked out in system of LabVIEW. Both tasks work with real mechanisms so they get real data and we can work with them further.

Optimalization of CMOS Chip Interconnection Process for Higher Current Load
Novotný, Marek ; Mach,, Pavel (referee) ; Hulenyi,, Ladislav (referee) ; Szendiuch, Ivan (advisor)
This work deals with silicon chip interconnection with a view to high current up to 10A. A wire bonding method is used for interconnection. The first part of investigation is focused on the modeling and simulation by the help of program ANSYS. Thermo mechanical stressing and current density is important parts of this research. Stress and current density distribution are results of the first part. The experimental part describes transition resistance, electro migration and thermal process in the connection of wire and chip pad. A controlled current source (0 – 10A) is used for measurement. The current source makes it possible to 4-point method measurement with sampling rate 1,5MHz.

Real Estate Activities
Bobková, Lucie ; Novotný, Marek (referee) ; Telec, Ivo (advisor)
The main motive of this work is that real estate agents and professionals engaged in real estate activities are negatively perceived by society. We assume that the professional misconduct of estate agencies, often mentioned in the media, is due to a lack of professional expertise. Therefore, we deal with the issue of education level of skilled workers at the real estate market in the Czech Republic. In a sample of 72 respondents, we try to find the level of professional expertise. This thesis notes and compares legislative standards and criteria for the performance of real estate activity in the CR and abroad. Further maps initiatives to improve the expertise and efforts to change legislation that would generally lead to a controlled expertise increase of the real estate segment at the market. It touches, examines and attempts to define the basic columns of expertise required for qualified performance of real estate activities

Graphical Filters for the AGE Project
Novotný, Marek ; Ježek, Pavel (advisor) ; Kofroň, Jan (referee)
The goal of this thesis was to develop a set of libraries for the AGE project. The libraries implement common transform, convolution (both high and low frequency) and color lters. The libraries also include an implementation of one-dimensional panoramas of overlapping images. All of the functionality is designed to seamlessly fi t into the AGE project class structure. In order to present the main results of the thesis a simple graphical editor was created as part of the thesis. The editor supports generation of panoramas as well as application of all the implemented filters to bitmap and vector images.
