Virtual laboratory modul development
Volf, Lukáš ; Novotný, Marek (referee) ; Vaško, Cyril (advisor)
Virtual laboratory is project aimed at creation of modern teaching instrument, which should help to students of microelectronics, but not only them, to understand questions of surface mount technology and packaging in electrotechnics. This work deals with analysis one of substantial part of the project, which is creation of interactive animations helping to understand questions of a given problems. In this work are described partial technological processes and their sequential application into interactive multimedia format.
The design of electrochemical sensor with integrated potentiostat chip
Uhlár, Martin ; Novotný, Marek (referee) ; Adámek, Martin (advisor)
The research on electrochemical sensor applications in combination with application-defined electronic circuits is a very fast developing field of modern sensorics. Device designing of unique integrated systems with specific properties and parameters is now becoming the everyday practice for producers of devices based on the latest technology progress in microelectronics. In the process of realization of a new device type, the main objective consists in increasing the possibility of detecting very low concentrations of heavy metals in the given chemical solution, extending the signal-to-noise ratio, and measuring the potential of a sensor. The general aim of this Master’s thesis is to design the topology of a sensor based on the thick film technology, to materialize the sensor, and to make experimental measurement using the sensor prototype. The practical reason for basing the measurement on the application of this thick film sensor is to find out whether the operational integration of the sensor and the circuit has been achieved according to the original hypothesis. Importantly, it is also necessary to determine whether the reproducibility of measured results has been reached. The innovative aspect of the created device consists in the improvement of output characteristics given by the integration of ASIC (IMAM CHIP). The integration of ASIC on the surface of the sensor eliminates the huge parasitic influence that affects the accuracy of measurement.
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.
Reduction of Contact Pairs Friction Losses
Novotný, Marek ; Raffai, Peter (referee) ; Maršálek, Ondřej (advisor)
This bachelor thesis deals with the topic of mechanical efficiency of contact pairs in the crankshaft of the combustion engine. The introductory section focuses on the efficiency of the combustion engine as a whole. In addition, it describes the areas where mechanical losses primarily occur. The following chapters describe mechanism of friction losses, the main factors affecting their amount and the most modern ways to increase mechanical efficiency. In the closing chapter, some basic computing relations, describing the size of mechanical losses are listed. The aim of this thesis is to acquaint the reader with the importance of mechanical efficiency in the area of combustion engines.
Development of church land ownership in the Czech republic and in the world
NOVOTNÝ, Marek
This thesis aims to acquaint the reader with the way in which the property originated and also with the subsequent development of this property in a historical context. The text is divided into four chapters. In the first chapter we can find a list of ways how was the church property originated. Next chapter deals with the development of church property on the territory of our country. The third chapter devotes the development of church property in Europe. The last chapter deals with the settlement of property of chosen countries with churches and religious societies.
Analyses of the factors affecting municipal policeman performance
Novotný, Marek ; Kovanda, Lukáš (advisor) ; Pichaničová, Ludmila (referee)
The bachelor thesis is talking about efficiency of municipal policeman in Prachatice. It is serving summary of factors that can influence their work efficiency. Also it analyses influence of the chosen factors. Based on regression analysis I evaluate data from panel model of the years 2010 -- 2013 and I show correlation of tobacco addiction and efficiency of municipal policeman. Then I prove correlation between increased traffic of inhabitants in the centre of the town (it is shown on the car taxes income and the season) and whole municipal police work. As the outcome of regression model is shown that smoking policeman has lesser efficiency -- he makes 24% less work than his non-smoking colleague. It means that non-smoking policeman makes 1,5 actions per shift more than smoking one.
