Abstract:

This diploma thesis deals with optimalization of the injection process of the part and its implementation into serial production. In the first step, the injection mold was tested and injection parameters were initially defined. In the next step, simulations were created in the CADMOULD program. These simulations calculated theoretical injection parameters and these were compared with the parameters set on the injection molding machines. Then, the shape measurement protocols were prepared, according to which the shapes in the cavities of the injection mold were optimized. Finally stress tests were performed, which detected problems in the injection process.

Abstract:

This dissertation thesis deals with determination of the mechanical properties of weld materials based on instrumented hardness test. This work was caused by the research project between IAM Brno Ltd and CEZ corp., when the task was to develop a methodology for evaluation of mechanical material properties using NDT methods. For these reasons the development of methodology is reflected especially for use in practice focusing to determining the mechanical properties of the heterogeneous weld joint on the assembled equipment. The mechanical material properties are determined by carrying out non-destructive tests of the instrumented Vickers hardness. The developed methodology for determining of basic mechanical properties is based on the principle of inverse FEM modeling of the instrumented hardness tests, when output of the testing is indentation curve and measured surface imprint after unloading. The basic material mechanical properties are achieved by comparing the outputs of the experimental instrumented hardness tests and the outputs of the modeled hardness test using FEM.

They are in form of compact parts and in form of thin coatings on the surface of metal parts. Fast development of constructive applications requires the same progress rate of machining ma-chines innovations and development of new methods of effective machining these materials, too. The aim is to produce parts of demanded shapes, dimensions and surface quality at affordable costs. Ceramics guarantee long terming durability and reliability. The evaluation of ceramics grinding tests from the point of view of cutting forces and surface quality of the machined faces are presented in the last part of the diploma thesis.

Abstract:

This thesis is focused on creation of mobilization curves, based on data, obtained from standard and detailed monitoring of the load test. The load test was performed on the 9 meters long ductile micropile. The first part of the thesis explains the methods and principles, which was used to construct the mobilization curves. Next there is description of the technologies of ductile micropiles and the load test. In the next part of the thesis is generally explained process, which was applied to the evaluated data. For evaluation was used spreadsheet Microsoft Excel and programming language Matlab, with Kernel Smoothing extension. In the last chapter of the thesis there are interpreted the load transfer function together with skin friction and micropile displacement.

Abstract:

The doctoral thesis deal with the interaction between the foundation plate and deep foundation in the form of bored piles in the case of skeleton construction. The issue of tension redistribution from the column between the plate and the pile is investigated on specific object – „Shopping and entertainment center Fórum Nová Karolina”. On this object were selected columns monitored and load tests of the piles was executed. Values of the axial loading of the piles and the actual deformation of the construction have been derived from measurements and tests. They were compared with the results of structural behavior by numerical modeling.

Abstract:

Acoustic pressure in environment protection programs of developed countries is the one of most important issue after air and water pollution. Acoustic pressure is all around us, such like machines, traffics and some other things. It is not possible to completely stop the noise, but there are some certain ways were used to reduce it up to acceptable limits. The aim of this work is to measure the acoustic noise and find solution to reduce it. The first measurements were done indoor (workplace studio) focused on room acoustic. We measured the acoustic pressure for three heights in different places,but finally the most important results were selected and compared with respect to each others. The next measurements were performed outdoor to collect the results about spread of the noise, which were analyzed with certain limits. The main goal was to find how to safe the human health and maintain peaceful and healthy environmental.

Abstract:

The presented thesis deals with the evaluation exterior of Moravian warm-blooded horse breed. The aim of the study was to evaluate the effect of statistical five selected effects (year of birth, sex, breed, breeder district headquarters, district headquarters of the owner) for five of the variables, which were points of evaluation "ZZUV" a basic body dimensions measured on the breed MT. The research began by defining comparable basis in the breadth of breeding individuals born between 1980 -- 2009 and registered to 1. 1. 2014 PK MT. It was about 200 breeding mares and 24 stallions. This was followed by the collection of necessary data using Microsoft Excel 2010. This was specifically about gender, year of birth, belonging to the breed, the number of points obtained in "ZZUV" values of body measurements, "PG" %, the highest performance achieved offspring of horses and monitored their color. This data were compiled statistical program continues Unistat 5.1 for Excel using the general linear model with fixed variables (GLM) and statistically significantly affected variables were forwarded to the multiple comparison method of Scheffe effects. All data were then divided into groups and compiled in tables and graphs. They represent the fair value and the percentage achievement on the one hand the whole population, but also compared gender stallions and mares.

Abstract:

This thesis originated as a part of the PhD research carried out by Mgr. Radek Suchomel. To calibrate a hypoplastic model for granular materials a large number of laboratory tests was needed and a part of the testing constitutes the present thesis. The hypoplastic model by von Wolffersdorff (1996) has eight materials parameters. The critical state fiction angle φc', which was obtained directly by the measurement of the angle of repose, is one of the eight parameters. Other parameters are determined form the results of experiments and empirically. Aim of this thesis was to carry out field and laboratory tests, to determine selected soil properties and to interpret them with regard to the variability of the soil in the selected face of the sand pit. The material for investigation comes from the south part of the Cretaceous Třeboň Basin in the South Bohemia from the Kolný sand pit. The pit is located in the upper part of the Klikov layers. The fluvial layers are characterised by rhythmical variation of gravely sands, sands and sands with dark grey clayey inclusion. Samples were taken in the face of the sand pit with the dimensions of 9 x 36 m. The following tests were performed: drained triaxial compression test (38 samples), oedometric compression test (38 samples), measurement of the angle of repose...

Title The effect of airway clearance techniques on patients with Chronic Obstructive Pulmonary Disease. Objective The main purpose of this study is to expose and evaluate the efficacy of airway clearance techniques on patients with Chronic Obstructive Pulmonary Disease by using pulmonary functions and Quality of Life measurements from recent studies. Methodology This thesis is literature review. The selected studies were according to inclusion and exclusion criteria. The selections of recent studies were published from the year of 2000 until 2017 in English language. The following research databases were selected to identify the relevant topic: PubMed, MEDLINE, Embase, Cochrane, PEDro, and CINAHL. The parameters' results from the articles have been also selected by evaluation the statistical differences according to the P-values. Results Twenty-three articles out of 117 have been found according to inclusion criteria, exclusion criteria, and outcome measures. The techniques were active cycle of breathing technique (ACBT), positive expiratory pressure (PEP), temporary of positive expiratory pressure (T-PEP), Oscillating positive expiratory pressure (O-PEP), high-frequency chest wall oscillation (HFCWO), slow expiration with glottis opened in lateral posture (ELTGOL), postural drainage, and autogenic...
