The life of the hydrogeological well is not important only in petroleum geology but also in the water industry. Nowadays, when the demand of water rises, it is necessary to ensure the smooth running of the wells and care as much as possible about their condition. The aim of this thesis is try to apply the methods of production analysis commonly used in oil production in the oil industry for water supply wells. In the thesis I will focus on monitoring the productivity of the well with regard to increasing the hydraulic losses caused by clogging. iv

This thesis establishes the need for a standardized, interoperable, front end interface to support the development of open RAN technologies, and establishes the viability and desirability of the VITA 49 interface standard as the alternative to other interface technologies. The purpose of this work is to propose a testbed platform for the further development for VITA 49 as a standard frontend interface as other current testbeds are not designed not as well suited to the VITA 49 standard or open RAN architecture. The VITA 49 interface standard provides a packetized interface between the front-end and the digital back-end of a split architecture system in a way that enables hardware interoperability between and within vendor supplies. The VITA 49 Radio Transport standard is ideally appropriate for integration into SDRs [12] due to its flexibility and metadata support. The REDHAWK platform is an integrated development environment which is used to develop a radio system that utilizes a remote radio unit to send and receive signals which transmits it using the VITA 49 protocol to the base band unit for processing. It was found that REDHAWK is better than GNURadio for this purpose, and that VRT technology is a much better than the current CPRI Standard as it provides an open standard, that enables a flexible, scalable interface that enables long-term growth.

Jakub Schinkman - abstract The object of the thesis was a detailed processing of the available temperature logging data from the area of Ohře lineament. The Ohře lineament is known by its characteristic temperature manifestations. Based on a comprehensive selection of thermometric logs and using the results of other logging methods were selected a total of 281 wells suitable for the construction of temperature maps. The parts of the work are maps of geothermal gradient and temperature sections across the Ohře lineament. Based on these summary maps, 6 smaller areas with anomalous temperature signs were selected for detailed analysis. Anomalies and trends in geothermal gradient were then compared with some other geophysical features. The work provides not only detailed processing of the collected thermometric data, but also shows the different possibilities of visualization and try to understand the problems of heat transfer in the upper parts of the earth's crust.

Background: Vestibular dysfunction, characterized by nausea, dizziness, imbalance, and/or gait disturbance, represents an important sport-related concussion (SRC) subtype associated with prolonged recovery. Vestibular physical therapy promotes recovery; however, the benefit of earlier therapy is unclear. Hypothesis: Earlier vestibular therapy for young athletes with SRC is associated with earlier return to play (RTP), return to learn (RTL), and symptom resolution. Study Design: Retrospective cohort study. Level of Evidence: Level 3. Methods: Patients aged 5 to 23 years with SRC who initiated vestibular rehabilitation therapy (VRT) from January 2019 to December 2019 were included and patient records were reviewed. Therapy initiation was defined as either early, ≤30 days postinjury, or late (>30 days). Univariate comparisons between groups, Kaplan-Meier plots, and multivariate Cox proportional hazard modeling were performed. Results: Overall, 23 patients (10 early, 13 late) aged 16.14 ± 2.98 years and 43.5% were male patients. There was no difference between group demographics or medical history. Median initial total and vestibular symptom scores were comparable between groups. The late therapy group required additional time to RTP (110 days [61.3, 150.8] vs 31 days [22.5, 74.5], P = 0.03) and to achieve symptom resolution (121.5 days [71, 222.8] vs 54 days [27, 91], P = 0.02), but not to RTL (12 days [3.5, 26.5] vs 17.5 days [8, 20.75], P = 0.09). Adjusting for age and initial total symptom score, earlier therapy was protective against delayed symptom resolution (P = 0.01). Conclusion: This pilot study suggests that initiating VRT within the first 30 days after SRC is associated with earlier RTP and symptom resolution. Further prospective trials to evaluate if even earlier VRT should be pursued to further improve recovery time. Clinical Relevance: Clinicians should screen for vestibular dysfunction and consider modifying follow-up schedules after SRC to initiate VRT within a month of injury for improved outcomes.

Volume rendering (VRT) has been used with great success in studies of patients using computed tomography (CT), much because of the possibility of standardizing the rendering protocols. When using magnetic resonance imaging (MRI), this procedure is considerably more difficult, since the signal from a given tissue can vary dramatically, even for the same patient. This thesis work focuses on how to improve the presentation of MRI data by using VRT protocols including standardized transfer functions. The study is limited to exclusively examining data from patients with suspected renal artery stenosis. A total number of 11 patients are examined. A statistical approach is used to standardize the volume rendering protocols. The histogram of the image volume is modeled as the sum of two gamma distributions, corresponding to vessel and background voxels. Parameters describing the gamma distributions are estimated with a Maximum-likelihood technique, so that expectation (E1 and E2) and standard deviation of the two voxel distributions can be calculated from the histogram. These values are used to generate the transfer function. Different combinations of the values from the expectation and standard deviation were studied in a material of 11 MR angiography datasets, and the visual result was graded by a radiologist. By comparing the grades, it turned out that using only the expectation of the background distribution (E1) and vessel distribution (E2) gave the best result. The opacity is then defined with a value of 0 up to a signal threshold of E1, then increasing linearly up to 50 % at a second threshold E2, and after that a constant opacity of 50 %. The brightness curve follows the opacity curve to E2, after which it continues to increase linearly up to 100%. A graphical user interface was created to facilitate the user-control of the volumes and transfer functions. The result from the statistical calculations is displayed in the interface and is used to view and manipulate the transfer function directly in the volume histogram. A transfer function generated with the Maximum-likelihood VRT method (ML-VRT) gave a better visual result in 10 of the 11 cases than when using a transfer function not adapting to signal intensity variations.

High-speed corridor is the future of travellibg. Many Eauropian states have begun with building it a few years ago and it works well. The Czech Republic still does not have this form of transport, but due to the location it will be necessary to build high quality railways even here for the future connection across Europe. This thesis deals with the construction of high-speed train stop (the HST) nearby the airport Brno Turany. The service follows the previous semestral work - Brno main railway station. The HST station building is drafted as a bridge over the rail and the platforms, it works not only as a check-in and waiting area but also like a pedestrian crossing over the corridor. The solid responds to the airport nearby and used bridge construction to smartly takes roof up. Public parts are at ground level, technical background and maintenance are located along the platforms below the ground level.

In this master's thesis, a numerical model of groundwater flow in a contaminated area of Hradec Králové was created. After that, a circulation well was introduced. Two circulation well variants, which differ in the amount of pumped water, were examined. All simulations were performed with the aid of a finite element solver Feflow 5.2. The values of hydraulic head resulting from the mathematical model are in a good agreement with those obtained from the field measurement. The groundwater flow present in the area of interest exhibits south to southwest direction. After introducing the circulation well, I focused on the influence of the amount of pumped water on the groundwater flow. The outcome of this observation was that during the higher volume pumping, the circulation cell is larger and therefore has a higher influence on the groundwater flow. I evaluated that it is more efficient to pump a higher amount of water in the investigated area.

Geothermal energy is one of the oldest forms of energy on our planet. Its use by humanity dates back to the beginning of the ages. The forms of this energy gradually changed from the direct heat of the hot springs, through the heating of the buildings and the baths to the later use of superheated steam for industrial use. Nowadays, there is a large share of the use of large number of ground geothermal boreholes with heat exchangers drilled in the matrix. The geometric arrangement of such system has a considerable impact on its operation. Specific examples show that, unlike the design, actual boreholes in such system can often be drilled non vertically or even curved. These imperfections then usually deteriorate the thermal properties of the system. This thesis demonstrates the influence analysis of the borehole geometry distortion on the system thermal properties, it also informs about the development of a special measuring device designed to obtain information about the actual geometric shape of the investigated borehole and about the development of software for in situ rapid borehole system properties evaluation. The theoretical part of thesis contains the derivation of a simplified numerical model of heat conduction in the vicinity of the borehole system. Its results serve to compare the different borehole variants and the inaccuracy of borehole shaping. Using the simulations, the influence of inaccuracies in the borehole system on its thermal properties is demonstrated in several model configurations. This effect does not occur in a single borehole, but it is significantly visible in organized geothermal borehole systems. It may deteriorate system properties, but under certain circumstances its properties may improve. Verification of the results of these simulations was performed by the FEFLOW simulation software. In the practical part the development of a special instrument for measuring the shape of a geothermal energy borehole is documented. ....
