Urbanisticko architektonické řešení nábřeží řeky Svitavy v Brně / Urban architectural design of the selected area by the river Svitava in Brno

Míčová, Markéta January 2015 (has links)
There is an opportunity for a new approach to the city adjacent districts by a combination of a reconversion and a modification of the former industrial estate of the Koffiller´s factory with a revitalization of the river Svitava and its feeding canal from an unused island. An introduction of the human spirit into an industrial environment using urban elements, green, public amenities and habitation brings about a better lifestyle.

Návrh optimálního zásobovacího procesu pro nové zakázky / The Suggestion of Optimal Supply Process for New Orders

Adamík, Vít January 2019 (has links)
The topic of diploma thesis was implemented in selected mechanical engineering company producing precision parts in small series. The main aim of the thesis is to create the suggestion of optimal supply process for new orders. The first part of thesis describes the company, area of its business and the processes of the order. In second part, the production analysis is carried out: production order path, production analysis for two reference parts, comparison of all time delay over two last years, find bottlenecks in the supply process. Base on analysis, theoretical approaches was described. In the last chapter there are suggestions for improvement of supply processes and thus shortening of production time of new orders.

Vodohospodářská analýza a boj se suchem v povodí řeky Rokytné / Water analysis and combating drought in the Rokytná river basin

Říha, Tomáš January 2020 (has links)
This diploma thesis focuses on water management analysis of the Rokytná River and finding suitable precautions usable by municipalities when dealing with drought and lack of water in their administrative district. The short research at the beginning of the thesis summarizes problematic of drought and lack of water in the Czech Republic, including the current state and overall context. Next part focuses on the assessment of current state of the Rokytná River basin, based on performed reconnaissance of the basin and processed analysis of a part of the basin delimited from km 0,0 to km 16,7 of the river, between towns of Ivančice and Moravský Krumlov. This analysis concentrates on finding factors, which can contribute to extent of drought impact in this area. It also contains a suspended load study of the waterway, which writes up granularity characteristics and calculation of the amount of transported material from a suspended load sample, taken from the bed of the Rokytná River. The overview of suitable proceedings and precautions follows, based on findings in previous parts of the diploma thesis. The conclusion of this thesis consists of very suggestion of suitable steps and precautions related to particular localities in the Rokytná River basin. Target is to enhance the retention ability of the region and to minimize the impact of both drought and floods. The result of these actions should be the empowerment of environmental sustainability in this particular area. Conclusions of this thesis can be used by municipalities and other administrative bodies when creating an approach of combating drought and when deciding about the implementation of relevant precautions.

Potenciál nefrekvenčních podpůrných služeb pro provozovatele distribuční sítě / Potential of non-frequency ancillary services for a distribution system operator

Reiskup, Filip January 2020 (has links)
This thesis provides a basic overview of the ancillary services in a transmission system. It summarizes changes regarding the implementation of European directives SOGL and EBGL. It describes in detail a portfolio of non-frequency ancillary services used in the distribution systems. It evaluates the demand of E.ON distribution system potential for those services in particular locations. Practical part is focused on a potential of reactive power management in this distribution area. It evaluates reactive power flow into transmission system and indicates the most critical substations. This thesis also covers analysis of existing resources in this distribution area and assign their possible potential in reactive power management.

Nestacionární CFD simulace toku uzavírajícím se tabulovým uzávěrem / Unsteady CFD simulation of flow under a downward moving gate

Málek, Miroslav January 2021 (has links)
Emergency gates are important safety feature of hydropower plants. They are used to close the flow in order to protect power plant equipment in case of emergency. In this diploma the-sis are realized CDF simulations of emergency closure of wheel-mounted gate on two-dimensional model of the Slapy hydropower plant. Simulations were performed for the case of constant lowering gate speed and for the case of gravitational closure. Dynamic mesh was used to enable the gate motion. The 6DOF method was used for the case of gravitational clo-sure and user defined function was defined to control movement of the gate. User defined function include gravitational force, hydrodynamic forces and friction force. Simulations were used to verify forces acting on gate and volume flow through gate during closing process. In case of gravitational closure the speed and orientation of closing process and closing process time were determined.

Program pro výpočet zkratových poměrů v elektrizační soustavě / Program for the calculation of short - circuit conditions in a power system

Bucholcer, Oto January 2009 (has links)
This master's thesis consists of three parts. The theoretical part deals with short-circuit conditions in the electricity supply system and with the method of their calculation. The practical part includes the programming process of a programme; description of programme properties and functionality. The third part contains the verification of an accurate programme calculation of the examples.

Návrh synchronního reluktančního motoru / Design of synchronous reluctance motor

Koshelev, Maxim January 2014 (has links)
Master thesis deals with analysis of the definite synchronous reluctance motor with salient poles and design of synchronous reluctance motor with barriers for magnetic flux. The work is divided into five parts. In the first part there is a brief overview of realized synchronous reluctance motor designs and also operating principle of motor of this type is described. The next part contains the basic parameters of the synchronous reluctance motor with salient poles; the parameters were found with analytical calculation. The third part demonstrates verified by means of FEMM results of analytical calculations for linear and nonlinear states and with transient analysis of motor using Ansys Maxwell environment. In the following part results of testing of the synchronous reluctance motor with salient poles are presented as well as the comparation of these results with calculated values and the results of simulations. The closing part of the thesis shows the design of synchronous reluctance motor with barriers for magnetic flux. All obtained parameters were examined using FEMM and Ansys Maxwell. The final version of the proposed motor was analysed when supplied directly by mains and through the converter by Maxwell- Simplorer co-simulation.
