Testování křemíkových detektorů pro experiment ATLAS Upgrade / Tests of Semiconductor Detectors for ATLAS UpgradeMartaus, Marek January 2021 (has links)
The semiconductor detectors of ATLAS experiment at CERN are exposed to high radiation for a long time, which reduces their efficiency. They need to be replaced and, if necessary, modernized. Nowadays, the entire Large Hadron Collider is planned to improve. Its luminosity will increase. During this shut- down, the detectors of ATLAS experiment will also be upgraded. This thesis is focused on strip detectors of a new inner detector of ATLAS experiment called ITk. For the correct interpretation of the measured results, it is important to know the detector's response. Test of detector response is, therefore, an important part of the process of developing. In this thesis, we focused on detectors' edges, where we assumed a different shape of the electric field, which may cause a different response. We chose the laser test because it is a position-sensitive measurement. 1

Využití interferometrie v VT UHV SPM / Application of Interferometry in VT UHV SPMŠulc, Dalibor January 2015 (has links)
The thesis is aimed at the development of Scanning Probe Microscopes (SPM). It describes design and development of modular controll electronics to be applied eectively on more microscopes SPM. Control electronics consist of stabilized power source, high–voltage amplier and probe signal amplier. The open–source project GXSM has been introduced. It contains a logic control unit which controls scanning, acquiring data and feedback control. GXSM provides a graphical user interface based on linux operation system. Second part of the thesis is aimed at design and development of interferometric deection sensing system for SPM cantilevers and applications at SPM in general. Designed interferometer has been assembled and tested. It can clearly distinguish a signal of amplitude 2 nm. At the end of the thesis the design of interferometric system implementation is presented.

Testování polovodičových detektorů pro projekt ATLAS Upgrade / Tests of Semiconductor Detectors for ATLAS UpgradeSýkora, Martin January 2017 (has links)
This thesis is focused on beta source tests of prototypes of ITk Strip modules at IPNP in Prague in the framework of the ATLAS Upgrade project. New expe- rimental apparatus will allow comparison of beta source test results with other testing methods including laser or test beam. I participated in the assembly of the whole apparatus, script development for a number of automated measurements using specialized ITSDAQ software and ROOT. Finally, summary of obtained properties of tested end-cap R0 DAQload with mini sensor is provided based on beta source tests and characterization of the readout chip. The resulting collec- ted charge value corresponds to 3.1 fC and together with often referred quantity signal-to-noise ratio, which equals 35, it is one of the most important results of the thesis. The experimental arrangement including overall analysis of results will be usable for the future production phase of the project. 1

This master's thesis deals with the issue of software tools for automated integrational ECU testing. It is specifically focused on TestAut 2 tool, which is developed by e4t company and used for testing of Skoda cars. Goal of this thesis is comparison of TestAut 2 against similar tools used in automotive industry. This work contains analysis of TestAut 2 tooland description of principles and features of EXAM, MODENA and PROVEtech tools. Set of principles considerd as advantageous is chosen from collected information. Next part of this thesis describes implementation of chosen principles to TestAut 2 tool, verification ofit's functionality and evaluation of it's benefits. In the conclusion author suggests another improvements that can be done.

Syntéza a charakterizace pokročilých molekul s implementovaným adamantanovým skeletem / Synthesis and characterisation of advanced molecules with implemented adamantane skeletonJančík, Ján January 2018 (has links)
This diploma thesis describes synthetic approach and characterization of advanced molecules with implemented adamantane skeleton and perspective use in attractive field of organic electronics. Three of four prepared molecules based on para-bis(2-thienyl)phenylene are original and totally new, and there were performed different synthetic approaches with comparison of yield, ecological and financial impact. Study of microwave synthetic approach was provided for cross-coupling reactions on para-bis(2-thienyl)phenylene skeleton. For all molecules were used ethyladamantyl and methyladamantyl substituents. Also, two completely new molecules based on 2,2':5',2''-terthiophene with ethyladamantyl and methyladamantyl substituents were prepared. In the next part were prepared new dimer structures of adamantane with possible application on field of polymers as bridge molecules. In the thesis were also made series of experiments for preparation of tetrasubstituted adamantane molecules, and for optimisation of preparation of spiroadamantane systems.

Vyhodnocování úrovně stresu pilota při přistání s využitím nositelné elektroniky / Evaluation of the pilot's stress level during landing using a wearable electronicsMuschalik, David January 2021 (has links)
The thesis focuses on the possibilities of objective stress measurement. It chooses parameters that are suitable for measurement by commonly available wearable electronics. It establishes a methodology for measuring stress using these devices, which it then verifies by conducting experiments with flight school students. It serves as proof of concept for similar measurements in further research or in flight schools.

Syntéza a optimalizace polymorfních obvodů / Polymorphic circuits synthesis and optimizationCrha, Adam January 2021 (has links)
Tato práce se zabývá metodami logické syntézy a optimalizací pro polymorfní obvody. V práci jsou jak diskutovány existující metody pro konvenční obvody, tak i představeny nové metody, aplikovatelné na polymorfní elektroniku. Hlavním přínosem práce je představení nových metod optimalizace a logické syntézy pro polymorfní obvody. Přesto, že v minulých letech byly představeny metody pro návrh polymorfních obvodů, jsou tyto metody založené na evolučních technikách nebo nejsou dobře škálovatelné. Z toho vyplývá, že stále neexistuje stabilní metodika pro návrh složitějších polymorfních obvodů. Tato práce představuje zejména reprezentaci polymorgních obvodů a metodiku pro jejich návrh založenou na And-Inverter grafech. Na polymorfní obvody reprezentované pomocí AIG je možné aplikovat známé techniky jako například přepisování [rewriting]. Nasazením techniky přepisování na polymorfní AIG získáme obvod, obsahující polymorfní prvky uvnitř obvodu, a je možné dosáhnout značných úspor prostředků, které mohou být sdíleny mezi dvěma funkcemi současně. Ověření návrhové metodiky pro polymorfní obvody bylo provedeno nad sadou veřejně dostupných obvodů, čímž je demonstrována efektivita metodiky.
