Characters and skills of managers
HLADÍLKOVÁ, Andrea
The aim of the work was to analyze and define managers´ characters and skills. Component aim of this work was finding out these characters and skills with subsequent evaluation and describing of present quality in management. Within the work the method of cause study and aimed (controlled) interview was used and on its basis the suggestions for improving were set. In order to complete this work together five managers from different branches who have been working at the top management grade were interviewed. During the individual interview the managers were asked different questions which they answered and they expanded their answers with related inducements. The questions were focused on characters and skills of interviewed managers, on their previous work experiences, on their highest achieved education and tasks and obligations associated with performance of their post. Interviews were directed at detail finding out of all needed information and were evaluated afterwards both individually and within the group. As a result of my own work, it emerged that emphasis on the concrete managers´ characters and skills is put differently depending on the branch where the manager works. Cardinal differences are obvious between the branches of operation and production. Because all of the interviewed managers are at the similar management grade, the same human and conceptual skills are present. However at the operation manager these characters and skills were shown as better developed due to increased needs and demands in this branch. Among identically mentioned characters the managers stated communication, motivation of their subordinates, ability to develop themselves and needed language skills. Among other mentioned characters and skills which were played up beyond only by some respondents belongs flexibility, quickness, ability to stay calm, knowledge of goods with subsequent releasing the products to the market. In my work I dedicate to the fact what extent were the managers born with their characters and skills and what part accounts for the characters got during their practice. According to the opinions of interviewed managers is the first opinion, which is possible to get and develop both by experiences and characters and skills. Only two of the respondents pointed to the fact that they were born with some needed characters and skills. One of the aims of my work was the comparison of theoretically obtained knowledge and information got from praxis. Most of the interviewed managers have not got university education predominantly they have secondary education finished by leaving examination. School was not pivotal for getting their present post. Most of the knowledge the interviewed managers have has been learned during practice and not by study. Principal theme in managers´ characters and skills is of course to extend the theoretically got knowledge. The manager can get this knowledge in the study at university or by attending a manager course. Nowadays the study at university and the manager courses offer the choice from different study forms. The manager does not have to finish his job but he can develop himself when working.

Clustering and regression analysis of micro panel data
Sobíšek, Lukáš ; Pecáková, Iva (advisor) ; Komárek, Arnošt (referee) ; Brabec, Marek (referee)
The main purpose of panel studies is to analyze changes in values of studied variables over time. In micro panel research, a large number of elements are periodically observed within the relatively short time period of just a few years. Moreover, the number of repeated measurements is small. This dissertation deals with contemporary approaches to the regression and the clustering analysis of micro panel data. One of the approaches to the micro panel analysis is to use multivariate statistical models originally designed for crosssectional data and modify them in order to take into account the within-subject correlation. The thesis summarizes available tools for the regression analysis of micro panel data. The known and currently used linear mixed effects models for a normally distributed dependent variable are recapitulated. Besides that, new approaches for analysis of a response variable with other than normal distribution are presented. These approaches include the generalized marginal linear model, the generalized linear mixed effects model and the Bayesian modelling approach. In addition to describing the aforementioned models, the paper also includes a brief overview of their implementation in the R software. The difficulty with the regression models adjusted for micro panel data is the ambiguity of their parameters estimation. This thesis proposes a way to improve the estimations through the cluster analysis. For this reason, the thesis also contains a description of methods of the cluster analysis of micro panel data. Because supply of the methods is limited, the main goal of this paper is to devise its own two-step approach for clustering micro panel data. In the first step, the panel data are transformed into a static form using a set of proposed characteristics of dynamics. These characteristics represent different features of time course of the observed variables. In the second step, the elements are clustered by conventional spatial clustering techniques (agglomerative clustering and the C-means partitioning). The clustering is based on a dissimilarity matrix of the values of clustering variables calculated in the first step. Another goal of this paper is to find out whether the suggested procedure leads to an improvement in quality of the regression models for this type of data. By means of a simulation study, the procedure drafted herein is compared to the procedure applied in the kml package of the R software, as well as to the clustering characteristics proposed by Urso (2004). The simulation study demonstrated better results of the proposed combination of clustering variables as compared to the other combinations currently used. A corresponding script written in the R-language represents another benefit of this paper. It is available on the attached CD and it can be used for analyses of readers own micro panel data.

Comparison of old and current cine lenses in combination with modern digital camera
Jakubec, František ; HOJDA, Petr (advisor) ; MIKŠ, Antonín (referee)
A Director of Photography has many artistic possibilities when working with cine lenses. Today, we can produce many optical effects in digital post-productions; however, working with lenses and with their defects (aberrations) is very interesting when you use them with modern recording technology. This thesis examines a small part of these issues. The theoretical part is about general qualities of optical systems, their aberrations, and measurement of picture quality. Furthermore, there is also a description of the movie camera and lenses, which were used for testing. The analytical part is about analyzing real footage from tests.

Effect of snowpack on runoff generation during rain on snow event.
Juras, Roman ; Máca, Petr (advisor) ; Ladislav , Ladislav (referee)
During a winter season, when snow covers the watershed, the frequency of rain-on-snow (ROS) events is still raising. ROS can cause severe natural hazards like floods or wet avalanches. Prediction of ROS effects is linked to better understanding of snowpack runoff dynamics and its composition. Deploying rainfall simulation together with hydrological tracers was tested as a convenient tool for this purpose. Overall 18 sprinkling experiments were conducted on snow featuring different initial conditions in mountainous regions over middle and western Europe.
Dye tracer brilliant blue (FCF) was used for flow regime determination, because it enables to visualise preferential paths and layers interface. Snowpack runoff composition was assessed by hydrograph separation method, which provided appropriate results with acceptable uncertainty. It was not possible to use concurrently these two techniques because of technical reasons, however it would extend our gained knowledge. Snowmelt water amount in the snowpack runoff was estimated by energy balance (EB) equation, which is very efficient but quality inputs demanding. This was also the reason, why EB was deployed within only single experiment.
Timing of snowpack runoff onset decrease mainly with the rain intensity. Initial snowpack properties like bulk density or wetness are less important for time of runoff generation compared to the rain intensity. On the other het when same rain intensity was applied, non-ripe snowpack featuring less bulk density created runoff faster than the ripe snowpack featuring higher bulk density. Snowpack runoff magnitude mainly depends on the snowpack initial saturation. Ripe snowpack with higher saturation enabled to generate higher cumulative runoff where contributed by max 50 %. In contrary, rainwater travelled through the non-ripe snowpack relatively fast and contributed runoff by approx. 80 %.
Runoff prediction was tested by deploying Richards equation included in SNOWPACK model. The model was modified using a dual-domain approach to better simulate snowpack runoff under preferential flow conditions. Presented approach demonstrated an improvement in all simulated aspects compared to the more traditional method when only matrix flow is considered.

Stareček, Lukáš ; Gramatová, Elena (referee) ; Kubátová, Hana (referee) ; Kotásek, Zdeněk (advisor)
This thesis deals with the possibilities of digital circuit test optimization using multifunctional logic gates. The most important part of this thesis is the explanation of the optimization principle, which is also described by a formal mathematical apparatus. Based on this apparatus, the work presents several options. The optimization of testability analogous to inserting test points and simple methodology based on SCOAP is shown. The focus of work is a methodology created to optimize circuit tests. It was implemented in the form of software tools. Presented in this work are the results of using these tools to reduce the test vectors volume while maintaining fault coverage on various circuits, including circuits from the ISCAS 85 test set. Part of the work is devoted to the various principles and technology of creating multifunctional logic gates. Some selected gates of these technologies are subject to simulations of electronic properties in SPICE. Based on the principles of presented methodology and results of multifunctional gates simulations, analysis of various problems such as validity of the modified circuit test and the suitability of each multifunctional gate technology for the methodology was also made. The results of analysis and experiments confirm it is possible for the multifunctional logic gate to optimize circuit diagnostic properties in such a way that has achieved the required circuit test parameter modification with minimum impact on the quality and credibility of these tests.

Navigation of mobile robots
Rozman, Jaroslav ; Matoušek,, Václav (referee) ; Šolc, František (referee) ; Zbořil, František (advisor)
Mobile robotics has been very discussed and wide spread topic recently. This due to the development in the computer technology that allows us to create better and more sophisticated robots. The goal of this effort is to create robots that will be able to autonomously move in the chosen environment. To achieve this goal, it is necessary for the robot to create the map of its environment, where the motion planning will occur. Nowadays, the probabilistic algorithms based on the SLAM algorithm are considered standard in the mapping in these times. This Phd. thesis deals with the proposal of the motion planning of the robot with stereocamera placed on the pan-and-tilt unit. The motion planning is designed with regard to the use of algorithms, which will look for the significant features in the pair of the images. With the use of the triangulation the map, or a model will be created. The benefits of this work can be divided into three parts. In the first one the way of marking the free area, where the robot will plan its motion, is described. The second part describes the motion planning of the robot in this free area. It takes into account the properties of the SLAM algorithm and it tries to plan the exploration in order to create the most precise map. The motion of the pan-and-tilt unit is described in the third part. It takes advantage of the fact that the robot can observe places that are in the different directions than the robot moves. This allows us to observe much bigger space without losing the information about the precision of the movements.

On-line Data Analysis Based on Visual Codebooks
Beran, Vítězslav ; Honec, Jozef (referee) ; Sojka, Eduard (referee) ; Zemčík, Pavel (advisor)
Práce představuje novou adaptabilní metodu pro on-line vyhledávání videa v reálném čase pomocí vizuálních slovníků. Nová metoda se zaměřuje na nízkou výpočetní náročnost a přesnost vyhledání při on-line použití. Metoda vychází z technik využitých u statických vizuálních slovníků. Tyto běžné techniky jsou upraveny tak, aby byly schopné se adaptovat na proměnlivá data. Postupy, které toto u nové metody řeší, jsou - dynamická inverzní frekvence dokumentů, adaptabilní vizuální slovník a proměnlivý invertovaný index. Navržený postup byl vyhodnocen na úloze vyhledávání videa a prezentované výsledky ukazují, jaké vlastnosti má adaptabilní metoda ve srovnání se statickým přístupem. Nová adaptabilní metoda je založena na konceptu plovoucího okna, který definuje, jakým způsobem se vybírají data pro adaptaci a ke zpracování. Společně s konceptem je definován i matematický aparát, který umožňuje vyhodnotit, jak koncept nejlépe využít pro různé metody zpracování videa. Praktické využití adaptabilní metody je konkrétně u systémů pro zpracování videa, kde se očekává změna v charakteru vizuálních dat nebo tam, kde není předem známo, jakého charakteru vizuální data budou.
