Work on determining the genetic diversity of biological signal aligning DNA sequences, will address a brief description of the composition of DNA. Following is basic information on the bioinformatics analysis. Then the work will describe the possibility of aligning DNA sequences. Work will focus primarily on global Needleman-Wunsch algorithm and local Smit - Watermanovův algorithm. Furthermore, this work will focus on aligning DNA sequences using methods CGR and FCGR. At the end of the work will describe the practical application of identifying genetic differences by aligning the sequences.

This diploma project is showen possibilities in classification of genomic sequences with CGR and FCGR methods in pictures. From this picture is computed classificator with BCM. Next here is written about the programme and its opportunities for classification. In the end is compared many of sequences computed in different options of programme.

The mechanical behavior of a high pressure die cast AM60B Mg alloy is studied. Constant load amplitude fatigue tests were conducted at room, elevated and cold temperatures, with a stress ratio of R=0.1, and frequency of 30 Hz. The objective was to identify the possible effects of temperature on fatigue life cycle. In addition, fatigue crack propagation tests were conducted to ascertain the fatigue response of the alloy and determine its fatigue crack growth rate as a function of the applied stress ratio, experimentally, analytically and computationally, using Walker’s model. The results demonstrated that temperature had a significant influence on the fatigue life, and that the life increased at cold temperature but decreased at elevated temperature as compared to that evaluated at room temperature. In this study, the limit for applicability of LEFM was established for AM60B magnesium alloy. In addition, fatigue crack propagation test results were used to evaluate the coefficients of the Paris model.
