Cutting cogwheal
Jindra, Pavel ; Osička, Karel (referee) ; Prokop, Jaroslav (advisor)
In my bachelory thesis I dwelled by machining of the frontal cog wheels. The main part of the whole work was to create a list of the machining’s methods, the list of a using of tools for individual machining’s methods and the list of the using machines for concrete methods. I appraised optimal methods in light of machining’s operation and it is in the conclusion of my bachelory work.

Position control of servo with discontinuouns rechangeable speed
Jindra, Pavel ; Věchet, Stanislav (referee) ; Němec, Zdeněk (advisor)
Diploma thesis work includes simulation of compensation of control for discrete. The aim of the work is a solution positioning control of servomotor drive piston, which is controlled by pass of the pressure oil with the help of several electromagnetically controlled switchboards with the orifice in the output channels. The verification activities of the regulated system is done using simulation in Matlab/Simulink and Matlab/Simulink, Matlab/Hydrosim. The requirement on the created model is to verify the behavior of the system to be modified to be used for the further development of the issue

Immunopathological and immunogenetic aspects of haematopietic stem cell and solid organ transplantations
Jindra, Pavel ; Boudová, Ludmila (advisor) ; Fakan, František (referee) ; Slavčev, Antonij (referee)
The genetic diversity of KIR genes and genotypes resembles of the HLA. Although the genes encoding KIR and HLA are located in different chromosomes and segregate independently, there is some evidence of some kind of co-evolution. Therefore, one could expect reduced KIR diversity within the HLA restricted population. A total of 41 unrelated individuals homozygous for ancestral HLA haplotype AH8.1 (HLA-A*0101-Cw*0701-B*0801- DRB1*0301-DQB1*0201), were typed for KIR genes. Over all, fourteen different genotypes were identified. The observed frequencies of KIR genes and genotypes composition generally mirror the published frequencies in Caucasians. Non-framework genes with frequency of more than 90 % included KIR2DL1, KIR2DL3, KIR3DL1, KIR2DS4 and KIR2DP1. Except for the KIR2DS4, all activating genes presented frequencies bellow 50 %. KIR2DS5 was the least frequent among activating genes (17 %), whereas KIR2DL5 (37 %) among inhibitory ones. The most frequent (39 %) was AA genotype. 22 individuals (54 %) had a copy of KIR haplotype A and B (AB genotype), whereas 3 (7%) were homozygous for B (BB genotype). Nine of 14 reported genotypes occurred only in one individual. Comparing with published and recorded genotypes (www.allelefrequencies.net), 5 genotypes were reported in less than 20 individuals worldwide and...
