Obnova vodní nádrže v obci Žďárná / Renovation of a water reservoir in the village of Žďárná

Pastorková, Nikola January 2022 (has links)
The theme of this diploma thesis is to restore the existing small reservoir in the village Žďárná. A new safety spillway and bottom outlet will be built, the flood will be shaped according to the cross-sections and the dam of the water reservoir will be fortified. The designed objects will be hydraulically verified. Using the HEC-HMS program, a hydrological model of the river basin is created and subsequently a derived flood wave PV20.

Revitalizace rybníka v katastrálním území Skalička u Hranic / Revitalization of the Small Water Reservoir in the Skalička u Hranic Cadastral Area

Majkus, Martin January 2022 (has links)
The aim of this paper is to propose a comprehensive revitalization of the side pond in the cadastral area of Skalička. As part of revitalization measures, the removal of mud from the pond, fortification of the banks and other modifications in connection with functional structures are proposed. In order to take water into the pond, a concrete diversion structure in the Hlubocky stream bed is designed, connected with pond via open canal with 2 pools, which will substitute the existing supply pipeline. As part of stabilization of the streambed and to overcome height difference, a boulder chute with stilling basin and related modifications are designed. The introductory part is a summary of knowledge from the issue and it explains important terms, historical context and description of basic principles. The next part describes the current situation and conditions in the surveyed locality. The following is a description of the methods and programs that were used for this work. The design part presents the proposed revitalization measures. An essential part of the work is also the varification of the proposed modification in the streambed, using 3D digital terrain model in Atlas DMT and subsequent 1D flow simulation in HEC-RAS.

Studie možnosti vybudování malých vodních nádrží v lokalitě u Vyškova na Moravě / Study of Possibility to Build Small Dams near Vyškov

Richter, Štěpán January 2012 (has links)
This thesis deals with the design of small reservoirs at Vyškov na Moravě. Projected reservoirs’ dams are earth-fill and homogenous and each one is equipped with the bottom water outlet and the emergency spillway. The first reservoir, located on the tributary of the Drnůvka river, has the fountain type emergency spillway and the feed pipe bottom water outlet. The reservoir of the Merchanice river, situated at the Vyškov airport, is equipped with the lateral emergency spillway and the feed pipe bottom water outlet. The third design is the reconstruction of the Marchanka reservoir projecting the dam raise. For this small reservoir two variants of functional installations were elaborated.

Záporné úrokové sadzby v kontexte hrozby deflácie / Negative interest rates in the context of deflation threats

Jenis, Filip January 2017 (has links)
The introduction of negative interest rates, as an additional tool of unconventional monetary policy in recent years, leads to many, yet largely polarized debates about the implications of the unconventional monetary policy of central banks. The main reason for their introduction in some economies, namely the threat of deflation, is also questioned, as well as the negative side effects of this instrument on financial stability and economic growth, and finally, their limited scope is under scrutiny. Due to the still insufficient research in this field, the aim of the diploma thesis is to evaluate the concerns and the main long-term risks and impacts of the monetary policy using negative interest rates in the context of deflation threats. The analysis of available data confirms both the concerns about the negative effects of negative interest rates on the banking sector, the recovery process of public finances, the possible rise of a price bubble on the financial markets and real estate markets, or on the possibility of excessive risk taking, and on the other hand draws attention to the direct dependence between negative impacts and the duration of monetary policy using negative interest rates.

Deformačně a napěťová analýza čelisti se zubním implantátem BOI / Stress - strain analysis of jaw with tooth implant type BOI

Marcián, Petr January 2008 (has links)
Submitted master thesis deals with stress - strain analysis of jaw, with dental implant. The implant serve as a suitable pillar for crown or dental bridge, when one or more teeth are lost. The project is oriented on BOI (basale - oseo - integrable) dental implant type, which is produced by DENTALIHDE company. Stress – strain condition of the mandible system with implant have been established by computational simulation, with use of the final elements method. Important part of down jowl is simulated on with EDS and EDDS applied types of implants. After implementation the implant begins to heal. Therefore the special attention is paid to stress - strain states on various level of osteointegration. There is a detail description of production of single part computational model and his solving in the master thesis. Presentation of large chapter with results and subsequent alteration stress - strain analysis is part of the master thesis. Program SolidWorks 2005 was used to create the geometric model. Computational model and the actual solving was accomplished with use of ANSYS 11.0 and ANSYS Wor-kbench systems.

Náhon posuvové souřadnice portálového obráběcího centra pomocí pastorku a hřebene / The drive of the feed coordinate portal machining center using a rack and pinion

Bartoš, Michal January 2019 (has links)
This diploma thesis deals with the design the drive of the feed coordinate portal machining center using a gear rack and pinion. The thesis contains researches from the area of CNC machining centers for non-rotating parts and sliding linear systems. Market analysis of portal machining centers of type of lower gantry with a gear rack and pinion was done. Furthermore, several design variants are proposed in terms of positioning the drive on the machine. These variants were further compared and the best option was selected for the specified machine. Subsequently, the technical calculation of the drive is performed and individual parameters and structural elements are proposed. The thesis also includes a 3D model of the proposed variant and the required drawing documentation.
