Větrání archivu / Ventilation of the archiveHudeček, František January 2019 (has links)
Ventilation systems for depositories have certain specifics. Their main objective is to provide safe environment for preserving unique cultural or other valuable objects that are being stored for extensive time periods. The economical aspect of the operation should be taken into ac-count and the ventilation system adjusted accordingly. This project also incorporates ventila-tion of secondary areas. Ventilation system is subsequently assessed in terms of indoor air quality (CFD simulation) and energetic requirements (program TRNSYS). Air quality in depositories is evaluated using age of air parameter. The qualitative and quanti-tative outcomes are obtained. Possible measures are then suggested to improve the air quality. The objective of energy simulation is to evaluate overall energy required for a year of opera-tion of main air handling units. In addition, estimation of energy requirements for heating and cooling are made for the whole building. The results are compared and more simulations are carried out in order to lower overall energy consumption.

Simulace obchodování na akciovém trhu / Simulation of transactions on Stock MarketUlrych, Stanislav January 2010 (has links)
This diploma thesis presents the simulation of the high frequency trading (HFT) strategies on electronic markets such as NASDAQ. The simulation is based on merging real historical order flow data and order flow of artificial trading agents representing new HFT strategies. This concept has not yet been widely discussed elsewhere. The problems discussed include: processing order flow market data, very precise time referencing, parametric reaction latency, various order types distinction etc. The design and the implementation of simulation process are presented, with respect to high computational requirements, modularizable strategies implementation and parallelization of whole simulation. In the final part of the work, we discuss the implementation and the results of a simulation of a simple HFT strategy.

Samoorganizace a optické vlastnosti malých molekulárních agregátů / Selforganization and optical properties of small molecular aggregatesSláma, Vladislav January 2013 (has links)
The work deals with the description of carotenoid aggregation in water solutions. The main interactions which are involved in aggregation were analyzed and an efficient way of description of carotenoid aggregation, which leads to a speed up the computation, has been introduced. In addition, two different methods for calculation probability distribution of catotenoids configurations in solutions with variable water concentration were elaborated, and their advantages and disadvantages were discussed. Absorption spectra were calculated from these distributions, and they were compared with the experimental results. The influence of water on formation of different types of aggregates, and its impact on the shape of absorption spectra was also discussed. Results of this study will be used as a base of other, more accurate, description of carotenoids aggregation, which will include other weaker interactions between carotenoids.

Simulace a testování stripových křemíkových detektorů pro experiment ATLAS Upgrade / Simulation and Tests of Strip Semiconductor Detectors for ATLAS UpgradeTheiner, Ondřej January 2019 (has links)
Together with the ongoing works on preparations of High-Luminosity LHC, there is a need to enhance the performance of various experiments on the collider as well. This is also the case of the experiment ATLAS and its subdetectors such as Inner Detector which will be completely replaced by new all-silicon Inner Tracker (ITk). This thesis deals with computer simulations of silicon strip detec- tors for ATLAS Upgrade ITk. For this purpose, we are using framework AllPix2 . It enables to simulate everything from the interaction of the particle with silicon, charge propagation in electric and magnetic fields, charge collection, up to signal digitization. We focused mostly on three aspects in the simulations. The first is a precise characterization of used detectors, the second is a simulation of a test beam measurements and the third one is a simulation of test measurements with a radioactive beta source. We also discussed the possibility of simulation of test measurements with a laser. These simulations are important not only because they help us to better understand processes happening inside the detector, but they are also used as a validation of testing measurements. As a result of this, we are able to point out the effects of the experimental setup (or detector itself) which have an impact on measured...

Možnosti využití simulačních postupů při analýze výroby Czochralskiho komory / Possibilities of using simulation methods to analyze the production of Czochralski chamberHrnčířová, Michala January 2011 (has links)
Simulation is a process that allows evaluation of a system from a comprehensive viewpoint. Thanks to this modern approach it is possible to find weak spots or other problems and solve them in the simulation model before applying the solution in a real situation. In my thesis I will focus on creating a simulation model of the production line of a Czochralski chamber in a specialized software named Simul8. Furthermore, I will deal with analysis of the various processes and the utilization of personnel involved in the production. I will also try to eliminate problems and discrepancies that show up by experimenting with the model. Based on the final results I will create recommendations that could help improve the real situation in the company.
