The Design of CRM System Subsegment
Drahošová, Hana ; Vlasák, Petr (referee) ; Klčová, Hana (advisor)
This Master's thesis is focused on an information system analysis and its component part design. The information system is developed using xRM platform or more precisely within the Microsoft Dynamics CRM 2013 system which is not, unline typical CRM, entirely available for sale thus certain adjustments need to be designed to meet the client needs. Given the extensive system comprising of 32 agendas, only one of them is designed in retailed here - the case of publication. Both the analysis and the design includes the MS Dynamics CRM 2013 standard working description.

Company of elears and the Czech War (1618-1620)
Vlasák, Patrik ; Županič, Jan (advisor) ; Valkoun, Jaroslav (referee)
The aim of this thesis is to describe the polish elears in services of the Habsburgs in 1618- 1620. The main focus is put on the cause of formation of this cavalry unit, and circumstances under which they began to serve in the services of the Austrian empire. I equally focus on their identity and their place of origin. I also try to analyze internal relations within the Polishh-Lithuanian Commonwealth and its foreign policy, which, I believe determined the very existence of the polish elears, that I percieve as one of the symptoms of crisis of the Polish-Lithuanian Commonwealth.

The Utilization of Ultrasound-guided Biopsy in the Management of Ovarian Tumors
Vlasák, Pavel ; Presl, Jiří (advisor) ; Fínek, Jindřich (referee) ; Zikán, Michal (referee)
Study objectives: To compare the diagnostic reliability, accuracy and safety of ultrasound-guided biopsy and ascites puncture in patients with primarily inoperable malignant tumor of the ovary. Study design: Retrospective and prospective data analysis Settings: Department of Obstetrics and Gynecology, Medical Faculty and Teaching Hospital in Pilsen Methods: We retrospectively analyzed a group of patients with primarily inoperable ovarian tumor, who underwent an ascites puncture with subsequent cytologic examination as a part of tumor verification before neoadjuvent chemotherapy commencement. The results were compared to a group of patients, who underwent an ultrasound-guided biopsy with subsequent histopathologic examination for determining of their diagnosis. We compared the adequacy, i.e. possibility to verify biologic nature, origin and histologic subtype of the tumor, accuracy, i.e. agreement between the result of the diagnostic method and final postoperative histology, and safety, i.e. recorded complications of the procedure. To validate the result of this comparative study we prospectively evaluated a group of patients where both methods were used. Results: In the ascites puncture group, a total of 55 procedures were performed. Adequate sample was obtained in in all patients and one severe...

Flow behaviour of sand-water mixture in horizontal and inclined pipes
Vlasák, Pavel ; Chára, Zdeněk ; Matoušek, Václav ; Kesely, Mikoláš ; Krupička, Jan ; Konfršt, Jiří ; Mildner, Michael
Pipelines transporting slurries in different industrial applications often contain inclined sections. The effect of pipe inclination, slurry concentration and mean velocity on the flow behaviour, deposition\nlimit velocity, and internal structure of a settling slurry was studied in an experimental pipe loop of inner diameter D = 100 mm. The slurry consisted from water and a narrow particle size distribution sand of mean diameter d50 = 0.55 mm. The experiments focused on the effects of the pipe inclination on solids distribution and deposition limit velocity. The concentration distribution in pipe cross-section was studied with application of a gamma-ray densitometer. The study revealed the stratified flow pattern of the medium sand-water mixture in inclined pipe sections. Experimental results show that the degree of the slurry stratification decreased with an increasing angle of inclination in the ascending pipe sections. The slurry stratification affected the deposition limit velocity. Mean in situ concentration for the descending flow was always lower than that for the ascending flow. The deposition limit in ascending pipe, in comparison with that in a horizontal pipe, slightly increased up to inclination angle about +25°, and then remained practically constant. For negative pipe inclination over – 30° no deposition limit was observed.

Effect of pipe inclination on local concentration and flow behaviour of settling slurry
Vlasák, Pavel ; Chára, Zdeněk ; Matoušek, Václav ; Kesely, Mikoláš ; Konfršt, Jiří ; Mildner, Michael
Settling slurry, consisted from narrow-graded sand of mean particle diameter 0.87 mm and water, was investigated on an experimental pipe loop of inner diameter 100 mm. The investigation was focused on the effect of the pipe inclination, slurry concentration, and velocity on concentration distribution, and deposition limit. The settling slurries tend to stratify, a layered structure is typical for a settling slurry flow. Slurry stratification is sensitive to pipe inclination, and differs for the positive and negative pipe inclination. Deposition limit increases with pipe inclination up to about 25°, and then remain nearly constant.

Vlasák, Patrik ; Valkoun, Jaroslav (advisor) ; Pavlíček, Tomáš (referee)
The thesis focuses on analysis of the standpoints within the British government and its representatives towards Poland during the January insurrection (1863-1864) in the context of international relationships and towards representatives of the Polish nation in Poland and in exile. The thesis further describes actions that were taken by the Polish emigrants in The Great Britain and their influence on the British foreign policy and society. Key words: The January uprising, Great Britain, Poland, Polish insurrection, 19th century, British-Polish relations

Effect of pipe inclination on flow behaviour of fine-grained settling slurry
Vlasák, Pavel ; Chára, Zdeněk ; Matoušek, Václav ; Konfršt, Jiří ; Kesely, Mikoláš
The effect of flow parameters of fine-grained settling slurry on the pressure drop-velocity relationship, deposition limit velocity and local concentration distribution was studied in an experimental pipe loop of inner diameter D = 100 mm with inclinable pipe sections for pipe inclination ranging from – 45° to +45°. The slurry consisted from water and narrow particle size distribution glass beads of mean diameter d50 = 0.18 mm. The concentration distribution was studied with application of a gamma-ray densitometry. The deposition velocity was defined as the flow velocity at which stationary deposit started to be formed at the pipe invert. The study revealed the stratified flow pattern of the studied slurry in inclined pipe sections, for slurry velocities below to the deposition limit sliding or stationary bed were created in ascending pipe sections. For low pipe inclination ( < ± 25°) the effect of inclination on local concentration distribution was not significant. Mean transport concentration for descending flow was lower than that for the ascending flow Deposition limit in inclined pipe was slightly lower than that in horizontal pipe. Frictional pressure drops in ascending pipe were higher than that in descending pipe, the difference decreased with increasing velocity and inclination.

Settling slurry flow near deposition velocity in inclined pipe of negative slope
Kesely, Mikoláš ; Matoušek, Václav ; Vlasák, Pavel
Pipe flow of sand-water slurry (settling slurry) is sensitive to pipe inclination. The effect of the angle to which the partially stratified flow is inclined from the horizontal has been subject to investigation in numerous studies. However, almost all of them focus on ascending flows, i.e. flows inclined to positive angles of inclination. It is well known that settling slurry flows inclined to negative slopes (descending flows) differ from those inclined to positive slopes, particularly at velocities near the deposition limit. The deposition limit velocity is the flow velocity at which stationary deposit starts to be formed at the bottom of the pipe. We investigate the effect of the negative slope on pipe flow near deposition limit velocity in the broad range of inclination angles. Besides the deposition limit, we focus on the distribution of solids across the pipe cross section. We combine experimental approach with mathematical modelling. Our new experiments with medium-to-coarse sand (mass-medium grain size 0.87 mm) in a 100-mm pipe inclined from 0 to -45 degree provide suitable data for a validation of predictions of our layered model for partially stratified flows in inclined pipes.
