This graduation work is about co-ordinal measuring machines (CMM) with optical reader system and optical CMM. In accordance with submission and in terms of survival well known contactless systems the direction is to make methodology objective classification of rating with granting summary of these systems. The first part contains optical principles for visual scanner in CMM and optical CMM. Ist is described there principle of contactless obtaining steric digital version of measured object with using laser and optical facilities. The second part contains brief makes survey of these contactless systems and their component which are used for co-ordinal measuring. The survey is devided into optical readers, which are put on CMM brake or on mobile measuring brake and on optical CMM, which localize position measuring/sensing head in the space or they read measured object from specific distance – fotogrammetric. Characteristic of offered systems and chart with technical data are mentioned with each maker. The third and fourth part is about submission methodology for objective choice suitable sort of reader, optical CMM in target of characteristic reader system quality. And from this methodology is given the choice of suitable exponent stationary measuring machine with contact and contactless way of reading and their comparison.

The Aim of this diploma thesis has been to analyse the application of the CNC machining centers for the production especially with concentration on accuracy and economical aspect of the machining process. After the study of the literature and making familiar with the production on the CNC machine tool of the type Deco Sigma 20 ( manufacturer, the firm Tornos ) it has been evaluated the technology of the design of the chosen part, its machining accuracy and found out the economical parameters of this machinery for this chosen part as a necessary supposition for securing the correct production in accordance with the requirements of the client. The described process of the technological and economical preparation for the production as well as its checking can be used in future for the proposals of the further similar parts.

This diploma thesis is engaged with problems of expressing measurement uncertainty especially for indirect measurements. This issue is shown here on a few simple examples. Part of this work is a calculation module for the determination of measurement uncertainties, applied to the role of the laboratory 'measurement of the flow orifice.

This diploma thesis deals with the unconventional technology of cutting water jet. The aim of this thesis is analysis of technological possibilities of water jet, possible operating modes (techniques) and entering technological data and influence of technical parameters on quality and accuracy of cutting. The thesis contains several experiment at which was examined achieved quality and accuracy of cuts, and simultaneously there is solved technoeconomic evaluation of this technology.

This diploma thesis focuses on the unconventional method of metal separation, namely on the cutting technology based on the plasma arc. The introductory part deals with studies which focus on the given issue from a theoretical point of view. The core of the work rests in the practical part which is dedicated to the production of samples using a plasma burning machine called Hypertherm HPR 260. The burned samples are monitored and assessed for the surface quality and dimensional accuracy for every created part. The final part of the work is dedicated to the techno-economic assessment of the burned parts. In the end, the evaluation of the attained results is made.

This thesis focuses on the issue of atrial fibrillation and the success of their detection in the ECG signal. It provides a description of electrical activity of the heart with the theoretical analysis of atrial fibrillation and methods for their detection. Additionally the work describes procedures for the implementation of three selected methods for the detection of atrial fibrillation in the MATLAB environment, presents the results of their tests on two atrial fibrillation signal databases and assesses the accuracy of each method.

The study is primarily focused on testing of the method which assesses sex from pubis. This method was originally proposed by Phenice (1969). Klales et al. (2012) modified this method in their study. They suggested to improve of the Phenice (1969) technique by extending the evaluation scale of three morphological traits from two values - present / absent to five development stage. Our study assumes that the success of Phenice (1969) method is related to the degree of sexual dimorphism of evaluated population. So the extension of evaluation scale will not lead to increased accuracy and will occur to decrease relibility of the method also. Intraobserver error was evaluated for Phenice (1969) a Klales et al. (2012) methods on the sample of isolated pelvic bones from Department of anthropology and human genetics of Charles university in Praque in first time. After we evaluated the whole sample, which consist of 200 three-dimensional models of pelvic bones. These models were segmented from CT images of adult individuals from contemporary French population. This sample was statistically evaluated by Cohen kappa, accuracy, senzitivity and specificity using confusion matrix and relationship between specificita and senzitivity was tested by ROC curves and area under curve (AUC). Results show that Phenice...

Title: The influence of kinematic factors on shooting velocity and accuracy in team handball. Goals: The main goal of this thesis is to find the influence of kinematic factors of throwing arm on shooting velocity and accuracy in team handball. Methods: The relationship between velocity and accuracy is based on practical measurement of group of team handballers. The measurement itself consists of three chosen types of shooting. We focused on movement and reciprocal position of reference points (ball, wrist, elbow and shoulder joint) and their influence on velocity and accuracy of hitting a target in goal. For measuring velocity is used a radar device Stalker. Measured values were elaborated in TEMA motion program which is appropriate for detail 3D analysis of throwing motion. Results: The results of this thesis demostrate the proximal-to-distal sequence in both types of throwing. An absolute velocities in this sequence were higher at Vmax shots than in accurate shots. There was found a significal difference between elbow extension angle of shots on upper and lower targets but exception. Higher elbow extension angle was found at Vmax shots than at accurate shots. This shows the influence of angle size on shooting velocity. A movement of the arm relative to vertical axis of a goal reflected an...
