A Comparison of Preconditioning Methods for Saddle Point Problems with an Application to Porous Media Flow Problems
Axelsson, Owe ; Blaheta, Radim ; Hasal, Martin
The paper overviews and compares some block preconditioners for the solution of saddle point systems, especially systems arising from the Brinkman model of porous media flow. The considered preconditioners involve different Schur complements as inverse free Schur complement in HSS (Hermitian - Skew Hermitian Splitting preconditioner), Schur complement to the velocity matrix and finally Schur complement to a regularization block in the augmented matrix preconditioner. The inverses appearing in most of the considered Schur complements are approximated by simple sparse approximation techniques as element-by-element and Frobenius norm minimization approaches. A special interest is devoted to problems involving various Darcy, Stokes and Brinkman flow regions, the efficiency of preconditioners in this case is demonstrated by some numerical experiments.

Levý, Jan ; Jelínek, Ivan (advisor) ; Profousová, Lenka (referee)
Analysis of unstructured data from social media is an important and constantly growing part of information technologies' application in the marketing context. The aims of this bachelors' thesis include creating a trial platform for the analysis of un-structured data from Facebook, research and application of suitable methods and metrics for the analysis, summarizing the analysis' findings and visualisation of selected metrics by means of a dashboard. The thesis' structure corresponds to the methods used for metting the aims set and compo-ses of seven parts. The first part summarizes motives for social media analysis, deals with the approach to the topic in the contemporary scientific papers and discusses comercial tools that could be used for such analysis. The second part describes gathering of data with a crawler, setting the connection and getting the access rights to the data sources. The structure of downloaded documents and appropriate choice of data sources is also described in this part. The third part adresses the tools used for the analysis, namely Elas-ticsearch and Kibana. The fourth part defines possible questions that may be asked in the context of Czech sports image on Facebook. The fifth part identifies the metrics necessary for the questions assesment and describes corresponding data selection. The sixth part completes the analysis itself and summarizes its findnings. The seventh part describes Ki-bana's dashboard use for effective summarizing of selected metrics. The main bachelors' thesis contribution lies in the illustration of social media analysis pos-sibilities on the example of Czech sportsmen and Czech sports in general on Facebook. A crawler has been used to gather the data for the purpose of the analysis. The other em-ployed tools included Elasticsearch and Kibana, which have enabled the data selection and visualisation. The analytical approach consisted of four parts; definition of analytical que-stions, definition of methods and metrics to find answers to these questions, followed by the analysis itself and the summary of results. The following points belong to the analysis' findnings: identification of sportsman with the highest marketing potential, comparison of analysed sports according to the perceived image by fans and desgination of the pages with most interacting followers.

Fluidized-bed Combustion of Dry Stabilized Sewage Sludge in Oxy-fuel Mode
Moško, Jaroslav ; Pohořelý, Michael ; Durda, Tomáš ; Zach, Boleslav ; Šyc, Michal ; Svoboda, Karel
Sewage sludge is an inevitable waste stream from wastewater treatment and its disposal is complicated due to specific characteristics of its composition. Sewage sludge combustion/incineration is the only suitable way for disposal of large volumes of sewage sludge containing POPs and some heavy metals. Sewage sludge combustion reduces the volume of such waste and causes destruction of organic contaminants. Oxy-fuel combustion is a technology for simplifying CO2 sequestration from the flue gas by using nearly pure oxygen instead of air for the combustion. In order to control the combustion temperature, part of the flue gas is recycled to combustion chamber. The paper brings information about investigation of the effects of combustion temperature and concentration of oxygen in inlet combustion media on the emissions of NOx, N2O and SO2 in FB combustion of sewage sludge. The experimental results have shown that an increase in combustion temperature leads to an increase in NOx and to a decrease in N2O emissions in the temperature range 750–930 °C. The lowest SO2 emissions were measured in the temperature interval from 800 to 820 °C in all experiments with different oxygen concentration in inlet gas. It was found that when the oxygen concentration in inlet gas increased, the emissions of SO2 increased while emissions of NOx slightly decreased.

Individual human odor as a forensic trail in criminal proceeding made by contact or contactless transmission and its resistance to physical agents
Santariová, Milena ; Bartoš, Luděk (advisor) ; Chmelíková, Eva (referee)
The dissertation thesis consists of four papers that have been published in scientific journals. Study n. 1 The need to recover evidence from water is quite common in criminal investigation. The article deals with the possibility to collect human scent from such objects and with the ability of specially trained dogs to match such scent samples with scent samples collected from detained suspects. During an experiment, designed as a blind one, it has been proved, that human scent can survive on submerged objects and can be later used for scent identification. Study n. 2 To collect odors the Czech Republic Police use special fabric sorbents manufactured under the registered mark ARATEX. Before use the fabric sorbent is treated by water vapor sterilization. After the scent identification the sorbent is destroyed. The goal of the study was to verify if the vapor sterilization is effective enough to remove human scent that has already penetrated into the sorbent structure or in other words if the sorbent can be exposed to vapor sterilization and then used again. Specially trained dogs were used to match starting odors with target odors in the line-ups. The results showed that dogs are able to correctly match human odors even after they have being exposed to vapor sterilization. Study n. 3 The purpose of the study was to determine the temperature at which the human scent is degraded so that a dog would not be able to identify it. In contrast to expectations, eight dogs used in the experiment almost flawlessly identified human scents from five scent donors exposed to temperatures of 100°C, 200°C, 300°C, 400°C, 500°C, 600°C, 700°C, and 800°C. Only two of the dogs were able to identify 5 of 15 scent samples exposed to 900°C. No dog identified a scent exposed to 1000°C. Our study verified heat survivability of human scent far beyond existing expectations. Study n. 4 We tested the hypothesis that if odor fallout (the release of a human odor onto an untouched object) in human subjects exists, then holding a hand above an absorbent will produce a detectable scent which will be subsequently matched in a detection test by trained dogs. Scents were collected from seven males to sterile cotton absorbent squares. The left hand was used to get the control scent and the right hand served as the target scent. Each experimental subject was sitting and his left hand was laid down on a cotton square for 3 min. The right hand was held 5 cm above another cotton square for 3 min. The scent identification was done by two specially trained police German shepherds. Both dogs performed 14 line-ups and correctly matched the collected scents of all test subjects. The results suggest the existence of human odor fallout, whereby a human scent trace is left by humans even if they do not touch an object.

Návrh apodizovaných-chirpovaných vláknových mřížek založený na metodách vrstveného dielektrika a přenosových matic
Helán, R. ; Urban, F. ; Mikel, Břetislav
This paper discusses methods for calculation properties of apodized-chirped fiber Bragg gratings (FBGs). These are one of the most enveloping optical devices in telecommunications and sensor systems. Work is aimed to design of FBGs with utilization especially in sensor systems and laser interferometry for semiconductor laser stabilization at wavelength about 760nm. FBG is described by periodic spatial function of effective mode index, including apodization and chirp profiles. Sampling makes function discrete and each sample represents one layer of dielectric media. The transfer matrix is made for each step. The overall transfer matrix is created by multiplying of these step-matrices. The spectral characteristic and group delay are calculated from overall transfer matrix at the end. This method provides design of arbitrary gratings, which are widely used in many optical systems, such as band filters, in-fiber sensors or fiber grating lasers and amplifiers for their unique properties.

Jev "zamrzlého pole" v elektricky vodivých médiích, řešený prostředky klasické elektrodynamiky
Doležel, Ivo ; Karban, P. ; Mayer, D. ; Ulrych, B.
The concept "frozen field" is often used in association with behavior of strongly electrically conductive media. Being introduced in astrophysics the phenomenon consists in drift of magnetic field by electrically well conductive medium (plasma or ionized mixture of gas and dust particles) that moves due to some primary mechanism not immediately associated with this magnetic field. This paper presents the description of the effect by means of classical electrodynamics in nonrelativistic medium and its solution in an integral formulation.

Joseph Kramolin (1730-1802)
Doleželová, Markéta ; Mádl, Martin (referee) ; Horyna, Martin (advisor)
As a theme of this diploma thesis I have chosen the personality and work of a baroque painter Joseph Kramolin. He had been working from the fifties of 18th century, till the beginning of nineteenth century. In the introduction of this paper I put the biographical data, in the following part I describe some of his works in chronological order. The painter was very efficient, so part of this paper is also the survey table of his work. After short training in Bohemia, the painter left for Vienna to improve his skills on academy of arts. However, he follows the tradition of czech high baroque art. His work is eclectic and of fluctuating quality. From 1758 he was oblate in Jesuit Order, after the S.J. was abandoned, he settled down in Karlovy Vary and stayed there for the rest of his life. Fresco paintings were the most important in his work, but he still produced also oil-paintings, especially portraits and work on religion subject-matter. In fresco he made a lot of ilussive paintings of altar architectures - for example in Hradec Králové, Tuchoměřice, Litoměřice, Klementinum - Prague, Holany, Chcebuz, Toužim, Mariánská Týnice, Libčany, Třebechovice pod Orebem and others. The very important part of his work were also figural fresco paintings, mostly in provincial churches - for example in Přelouč, Chcebuz,...
