Parity vertex colorings
Soukup, Jan ; Gregor, Petr (advisor) ; Kučera, Petr (referee)
A parity path in a vertex colouring of a graph G is a path in which every colour is used even number of times. A parity vertex colouring is a vertex colouring having no parity path. Let χp(G) be the minimal number of colours in a parity vertex colouring of G. It is known that χp(Bn) ≥ √ n where Bn is the complete binary tree with n layers. We show that the sharp inequality holds. We use this result to obtain a new bound χp(T) > 3 √ log n where T is any binary tree with n vertices. We study the complexity of computing the parity chromatic number χp(G). We show that checking whether a vertex colouring is a parity vertex colouring is coNP-complete and we design an exponential algorithm to com- pute it. Then we use Courcelle's theorem to prove the existence of a FPT algorithm checking whether χp(G) ≤ k parametrized by k and the treewidth of G. Moreover, we design our own FPT algorithm solving the problem. This algorithm runs in polynomial time whenever k and the treewidth of G is bounded. Finally, we discuss the relation of this colouring to other types of colourings, specifically unique maximum, conflict free, and parity edge colourings.

Soukup, Jan ; Šťastný, Petr (advisor) ; Arnošt, Pavel (referee)
Title: Methodology for development of skating technique on a skatemill Goals: The objective of the present study is to compile available methodology knowledge re-garding the improvement of skating technique using a skatemill, and to analyse the pro-gress of skating technique in selected ice-hockey players during a comprehensive train-ing programme, where a skating simulator is used. Keywords: Ice Hockey, skatemill, kinematic analysis, hockey skills, motoric skills, ska-ting, modern aids. Powered by TCPDF (www.tcpdf.org)
Channels eroded by groundwater flow in Strelec quarry: erosion processes and factors influencing channel evolution
Soukup, Jan ; Bruthans, Jiří (advisor) ; Grmela, Arnošt (referee)
Large depression cone in water table was formed due to mining in surroundings of Střeleč quarry. The concentrated inflow from conduits to quarry is up to 70 l/s. Large conduit systems are created by flowing water into the quarry. The biggest conduit system was at least 300 m long and 17 m high with maximum calculated volume of 22 thousands m3 . Evolution of these conduits usually takes several months to few years. Fast conduit evolution allows to study erosion processes in detail in situ. In the thesis I am describing conduits, character of flow and erosion processes. Measured flow velocities in conduits are up to 0,4 m/s with hydraulic gradient 1 to 5%. Flow velocities and hydraulic gradients are typical for piping erosion. Piping initially forms small protoconduits. The bigger conduits are formed as water is progressively drained from larger area. Conduits are following fracture surfaces, which are also limiting the conduit propagation to the sides. Above water table the conduits are enlarged mainly by mass wasting of undercut sandstone slabs. For distinguishing less and more erodible parts of sandstone, we adapted and partially developed a method for measuring erodability (REI) and drilling resistance (DR). Both are used to compare different types of sandstone surfaces. In lowermost part of the...
Sapping- its field features and studies focused on detail description of the process
Soukup, Jan ; Bruthans, Jiří (advisor) ; Schweigstillová, Jana (referee)
The study discuss about groundwater sapping erosion, whereas is upon process looked from various points of view. In small scale it observes difference between sapping drainage network and network formed by surface runoff. Further forms of the sapping weathering are described and are mentioned examples of sapping valleys from different places around the world. Partially are mentioned actual knowledge in evolution of deep incised valleys on the Mars surface, which are obviously also formed partly by sapping. In the second part, study describes some experiments focused on evolution of sapping valleys in laboratory environment.
Outsourcing success factors and comparison of the most successful countries and the Czech Republic
Soukup, Jan ; Očko, Petr (referee) ; Basl, Josef (advisor)
This paper topic are outsourcing success factors and situation in this branch in India, China, Russia and Ireland as they are considered to be the most successful countries in outsourcing nowadays, and in Czech Republic. The goal of this work is to analyse the most important outsourcing success factors and describe the possibilities to break through which Czech companies potentially may have in this branch. This work deals with different ways of seeking the information which are related to outsourcing and to the compared countries. Main attention is focused on professional database centres, services which they provide and query languages which an information specialist will meet while using these database centres. There are different types of operators and query languages described, highlighted are differences between the so called visible and nonvisible web. Every chosen country is evaluated by few particular criteria, e.g. government support or the most important industries in which outsourcing has been applied or might be applied in the future. Special attention is dedicated to the support of foreign investments in Czech Republic
Dissociation in adolescence. Validation of the Czech version of the A-DES in the clinical and non-clinical group of adolescents
Soukup, Jan ; Papežová, Hana (advisor) ; Hrdlička, Michal (referee) ; Praško, Ján (referee)
The purpose of this study was to find psychometric properties of the Czech language version of the Adolescent Dissociative Experiences Scale (Armstrong et al., 1997). 653 non-clinical participants and 162 adolescent psychiatric inpatients completed Czech versions of the A-DES and SDQ-20 questionnaires (Somatoform dissociative questionnaire; Nijenhuis et al., 1996), and provided further information (data regarding demographic variables, diagnoses, further psychopathology). The Czech A-DES has very good internal consistency, test-retest reliability and a good validity, though its predictive power is limited. The ADES scores significantly correlate with the measure of somatoform dissociation, self injurious behavior, reported traumatic experiences, a presence of clinician-observed dissociative symptoms, and polysymptomatic diagnostic picture (three comorbid diagnoses, differential diagnosis). A-DES scores were significantly higher in ADHD group, but not in a group with a diagnosis of a dissociative disorder. The study supports the intercultural validity of the concept of the dissociation and its clinical correlates; however, further research of the intercultural differences is needed. The authors stress the need to screen all adolescent psychiatric patients for dissociation, especially those who show more...
Business models on deep web
Soukup, Jan ; Šebesta, Michal (advisor) ; Bruckner, Tomáš (referee)
This diploma thesis analyzes the deep web environment with the use of business models from the surface web. In the indroduction part of the thesis summarize terms web, deep web and dark web, these terms are intermingle the entire thesis, also brings the concept on Onion routing with use of Tor software. An inseparable part is the comparsion of tools which can be used for access to the dark web. The main part of the thesis analyzes most used business models on the surface web including their methods of monetization and after that author tries to apply these models in the dark web environment. An importat part of this work is the analysis a type of services occuring on the dark web and mutual comparison of several sub-criteria of each service. In the final part the thesis presents project Turris on which is applied to create a relay node for the Tor network.
