Motivation as a leadership
Klimešová, Andrea ; Fiedler, Jiří (advisor) ; Horáková, Jana (referee)
Summary
This bachelor thesis is focused on Motivation as leadership. It depends on methods
of motivation that are applied by managers in leading their employees. It is about
how correctly and effectively they are using their motivation for leading their employees. The thesis consists of two parts theoretical and practical.
The theoretical part includes the most basic terms which are important
for understanding this theme. Theoretical part is processed and derived by literature
mentioned below. At the introduction are discussed concepts such as management,
the manager and his competence or roles. For better understanding which role motivation captures for managing people, all concepts are explained, such as leadership styles, motivation, incentive and communication, which are important for leadership.
The practical part is based on structured interviews with managers, it is down their answers which were compared. Structured interviews are based on the twelve important issues which five managers from three different companies are asked about. Finally,
the evaluation of their responses, resultant comparison and final answer about how they put emphasis on executives for motivation.

Influence of Resource Sharing on Performance
Babka, Vlastimil ; Bulej, Lubomír (referee) ; Tůma, Petr (advisor)
Resource sharing occurs when multiple active processes or software components compete for system resources, which influences the observed performance compared to an individual execution. Isolated benchmarking of durations of key operations for solving of performance prediction models may therefore yield imprecise results. Resource sharing also occurs between the measured code and the benchmark infrastructure for obtaining and storing samples, imposing an indirect overhead. This thesis quantifies the effects of sharing on performance for several resources that are often shared, namely the processor caches and the file systems. The highest possible performance impact of cache sharing is determined by synthetic benchmarks. Impact on practical code and its dependency on a number of factors such as cache trashing frequency and intensity are then determined by experiments with existing implementations of FFT and LZW algorithms and a video stream processing application. Effects of file system sharing are measured by experiments that read and write multiple files simultaneously. For both resources, situations with significant performance impact of sharing have been observed. Based on the results of the experiments, several suggestions for dealing with the overhead of performance monitoring infrastructure are...

State contribution to building savings
Kasalová, Monika ; Urbánek, Václav (advisor) ; Bušovský, Ladislav (referee)
This bachelor thesis examines how state supports the building savings in Czech Republic. Because of the fact, that state expenditures on this support are part of public expenditures, in the first part I focus on its characteristic and division. Then I continue more specific in description of mandatory expenditures. I describe its structure and analyse its development in years from 2000 to 2013. In the second part I deal with construction, development of state support on the basis of legislative changes which occured during this years of application this product on the Czech market. The last part of my thesis is dedicated to analysis of possible changes in building savings and its impact on state budget and on the whole system of this field.

Ion attachment and ion emission of dust grains
Vyšinka, Marek ; Němeček, Zdeněk (advisor) ; Wild, Jan (referee)
Small dust grains could be found in many environments. Because of their size, their charge and the electric forces acting on them play an important role in their dynamics. The dust grain charge is influenced by many different processes. Among other methods, charging processes can be studied by trapping a single dust grain inside an electrodynamic quadrupole where it is put into specific environment (ion or electron beam, UV radiation). The progress of the charging process can be inferred from the changes in the grain charge. Our work contributed to the building of a new laboratory set-up for study of the charging processes. Specifically, a new Faraday cup for measurements and stabilization of the ion and electron gun currents is designed and its function verified. It solves the shortcomings of the previously used Faraday cups. Further, an amplifier for the ion gun current measurement is designed and constructed along with the design of digital stabilization of the current. The stabilization is neccesary for the interpretation of measurement results and its digitalization will allow more flexible adjustment and easier connection with the control computer. Finally, data acquired during the charging of dust grain with different ion species are evaluated in order to study the effect of different ions on surface...

Evaluation of chat bots
Hazdra, Jan ; Sigmund, Tomáš (advisor) ; Čermák, Radim (referee)
This thesis deals with the evaluation of theability of machines to imitate human behavior. Presents a brief history of the development on the field of artificial intelligence and intelligent machines, specifically chat botsand describes their evolution throughout the 20th century. It describes the most important features and building blocks of chat bots, including the most widely used programming languages for creating them.It also describes the theory of A. Turing, the test and the imitation game, on which is based methodology for evaluating chat bots. Then it also examines the criticism of the Turing's test by J. R. Searle's chinese room argument that is used for its better understanding and finding its boundaries. The work also describes H. Dreyfus's assumptions, which led to optimism in the late 90s in development in artificial intelligence and limits of artificial intelligence, on which he pointed out. The main objective is the metodology proposed in the second part, which is used for comparing selected chat bots and then used for their evaluation. Overall evaluation consists of evaluations in the sub-categories in which will be individual chat bots scored. The methodology is based on the Turing test, which slightly modifies, but also extends thanks to the ideas of other authors.

Novel photonic stuctures for integrated optics
Čtyroký, Jiří
Two perspective construction principles of modern integrated-optical circuits are briefly described: systems based on microresonators as basic building blocks, and integrated-optic structures utilising two-dimensional photonic crystals in optical waveguides. Both approaches are nowadays in the centre of attention of leading research laboratories for their pertinent potential of mass production of integrated-optical structure for junctions and terminals of high-capacity optical communication systems.

The role of evolutionarily conserved proteins BIR-1/Survivin and SKP-1 in the regulation of gene expression
Kostrouch, David ; Kostrouch, Zdeněk (advisor) ; Dráber, Pavel (referee) ; Pacák, Karel (referee)
SKIP and BIR/Survivin are evolutionarily conserved proteins. SKIP is a known transcription and splicing cofactor while BIR-1/Survivin regulates cell division, gene expression and development. Loss of function of C. elegans SKIP (SKP-1) and BIR-1 induces overlapping developmental phenotypes. In order to uncover the possible interactions of SKP-1 and BIR-1 on the protein level, we screened the complete C. elegans mRNA library using the yeast two-hybrid system. These experiments identified partially overlapping categories of proteins as SKP-1 and BIR-1 interactors. The interacting proteins included ribosomal proteins, transcription factors, translation factors and cytoskeletal and motor proteins suggesting involvement of the two studied proteins in multiple protein complexes. To visualize the effect of BIR-1 on the proteome of C. elegans we induced a short time pulse BIR-1 overexpression in synchronized L1 larvae. This led to a dramatic alteration of the whole proteome pattern indicating that BIR-1 alone has the capacity to alter the chromatographic profile of many target proteins including proteins found to be interactors in yeast two hybrid screens. The results were validated for ribosomal proteins RPS-3, RPL-5, non-muscle myosin and TAC-1, a transcription cofactor and a centrosome associated...

Zjednodušení kvantových obvodů pro modulární umocňování
Fišer, Petr ; Ivánek, Jiří (advisor) ; Nentvich, Libor (referee)
This thesis is based on top of the previous thesis "Security of modern encryption protocols" where we introduced a new paradigm for constructing quantum circuits. We have built circuits for modular arithmetic (addition, multiplication and exponentiation) in order to break El-Gamal asymmetric cryptosystem. Current thesis reviews all proposed circuits and discusses possibilities of their further optimization in goal of lowering the number of used qbits at least by an order of magnitude. It also shows that this is not possible due to existence of COPY gates which make the design inherently unoptimizable. Getting rid of COPY gates is, however, not possible without substantial rewrite of the whole paradigm. The overall estimate of number of qbits used in circuits thus remains O(log(m)log^2(N)) where m is a processed number and N is a modulus. The thesis also proposes optimization of the modular multiplication circuit that, if issues with COPY gates are resolved, allows us to lower the number of used qbits by about O(log(m)) at the price of a longer execution time.
