Hodnocení konstrukčních detailů budov z pohledu energetické náročnosti / Construction details of buildings evaluation from energy demand point of viewCísař, Milan January 2018 (has links)
Theoretical part of Diploma thesis deals with issues about thermal bridges and thermal connections in building structures. The Calculating part focused on the family houses with a low heat use. The results of this part are energy and financial evaluations of family house. The last part deals with the using of computer technology in engineering practice. These chapters devote about computer modeling an assembly details of passive house and family house after reconstruction (the dates of family house after reconstruction are compared with the results from experimental measurements). The last section of this Diploma thesis solves dynamic modelling of particular passive house in simulation program called Trnsys.

Optimalizace distribuční soustavy 110 kV v uzlové oblasti Přeštice / Optimization of the 110 kV distribution system in the Přeštice nodal regionNagy, Pavel January 2019 (has links)
This work describes an actual condition of a specific part of a distribution power grid. It is a research of problems based on the computer model in case some power line is in failure or shut down. Simulations are calculated for both currently used load and load expected in future usage. There are partial solutions depicted for each issue found during the simulation. Some of those are used for a final design of a distribution power grid. In the last section, there is a comparison of different types of power lines and their possible usage in the design.

Modelování planárních vazebních členů / Modeling of planar coupling circuitsValošek, Josef January 2008 (has links)
This master’s thesis deals with modelling of the planar coupling circuits, namely type of the wideband couplers and the ultra-wideband couplers. The purpose of this thesis is an analysis, a synthesis, a numerical modelling and a fabrication (only chosen types) of the presented couplers. All of the couplers works on medium frequency f0 = 7 GHz with coupling C = 3 dB. Types of the substrate are Arlon 25N and Arlon AD600. EM simulator IE3D and circuit simulator in program Ansoft Designer are used for the numerical modelling. The realized wideband couplers were measuring by the vector analyzer Agilent E3864B.

Ochrana obce Světnov před extravilánovou vodou / The protection of small village Světnov against rural zone waterHumlíček, Aleš January 2013 (has links)
The aim of this thesis is to propose appropriate flood protection measures in the small village Světnov, calculate the critical flood of guideline for very small basin and insert the data into the program HEC-RAS 4.1.0, where they will be further treated in order to find the most appropriate and effective solutions. As flood control measures will be designed two dry polders east of the village. Dikes should be designed so to be able to accommodate 100-year flood, which will be calculated according of guideline for very small basin. Of the materials community, we know that we need to convert flood into the existing pipeline, which is able to accommodate 1 m3/s. The thesis will design solutions dams, sewage channels and function objects in the program AutoCAD 2008.

Technologie příjmu extrémně slabých radiových signálů meziplanetárních sond / Technology of Receiving of Very Weak Signals from Interplanetary SpacecraftsŠpaček, Jiří January 2012 (has links)
The work deals with the problematics of receiving very weak radio signals and it is focused especially on systems for low rate telemetry with carrier-subcarrier modulation. The part of this work is dedicated to calculation the link budget of typicall telemetry data transmission system between the Mars and the Earth in respect of the receiving equipment, which could be developed in the Experimental sattelites laboratory on the Institute of radio electronics BUT. The main part of this work is dedicated to developing and testing the low rate telemetry data transmission system model. The model is developed for the purpose of study the effects of AWGN and phase noise on the whole system and also on its component parts. The model has been developed and described in the way of easy parameters modification. The design for each parameter of the model is described carefully. With the developed model, the study of the effects of AWGN and phase noise on the whole system and also on its component parts has been performed.

Mechanické vlastnosti a struktura směsí recyklovaného polyetylénu a velmi nízko hustotního polyetylénu / Mechanical properties and structure of blends of recycled polyethylene with linear low density polyethyleneKocandová, Jana January 2019 (has links)
Recycled material produced during three months from packing polyethylene foils coming from three suppliers was analysed together with one recycled material under complaint from the point of melt flow index (MFI), composition and mechanical properties. The addition of linear low density polyethylene (LLDPE) into the recycled material was studied as well. It was measured melt flow index (MFI), Differential scanning calorimetry (DSC) together with Thermogravimetry methods were used to determine composition. Selected materials were pressed to obtain films with the thickness of 1 mm to determine tensile properties. Recycled materials contained 40–65% LLDPE, small amount of polypropylene as well as chalk. The content of LDPE and LLDPE varied within one supplier and thus mechanical properties did. The results showed the difference in quality of PE films separation among all suppliers. The problems with workability of material under complaint were caused by the material composition – the amount of LLDPE predominated. The addition of LLDPE into the recycled material in the range of 5–20 % increased MFI by 13-78%. Mechanical properties of blends rich in LLDPE were similar to those of clear LLDPE. The presence of LDPE influenced more markedly only the strength to break. The blends of LDPE and LLDPE were evaluated as immiscible but with high affinity of the components with increasing contend of LLDPE. No material was chemically degraded. The methods commonly performed in manufacture, especially MFI, are not able to differentiate LDPE form LLDPE – recommended is DSC.

Vývoj pokročilých tepelně izolačních omítek s možností uplatnění jako sanační omítky dle WTA / Development of advanced thermal insulating plasters with utilization as sanitation plasters according to WTA standardVaněk, Lukáš January 2014 (has links)
The theoretical part of the thesis is devoted to the issue thermal insulation plasters which can be applied in the remediation of buildings. The practical part deals with optimizing the composition of thermal insulation plaster-based lightweight aggregate of the foam glass and with possible substitution of cement for other binders with latent hydraulic properties. The resultant plaster should meet the best ratio of mechanical and thermal insulating properties.

Mechanické vlastnosti mořských sedimentů v okolí přístavu Koper a numerické modelování hluboké základové jámy / Mechanical properties of marine sediment near Koper and numerical modelling of a deep excavationTůma, Pavel January 2010 (has links)
Mechanical properties of marine sediment near Koper and numerical modelling of a deep excavation Engineering geological conditions near the port Koper in southwestern Slovenia forces geotechnical experts and civil engineers to solve problems in foundation various types of objects and purpose of the practice since the fifties of last century, when it began an intensive development of infrastructure of the port. The results of series of geological and geotechnical surveys, monitoring, and long experience with foundation in the local geology shows that it is almost always the 3rd geotechnical category, or foundation of complex structures in difficult geological conditions below the water table. The entire area belongs to Alpine-Dinaric tectonic area. The rock foundation is composed of complexes of flysch sediments Eocene age at which mounted files of recent marine sediments in the area widely submerged river valley fluvial sands and gravels. From the geotechnical point of view it is interesting site, where most buildings were based on a layer of soft marine sediments, where it is through the creation of special methods implemented in the establishment of deep-level endurable layers of gravel and sand of the river Rižana or at the level footingwall flysch. Set of marine sediments near the port Koper,...
