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

Title: Measurement of Time-Dependent CP Violation in B0 → ηcK0 S at Belle Experi- ment, Optimization Studies of the Belle II Vertex Detector Author: Zbyněk Drásal Department: Institute of Particle and Nuclear Physics Supervisor: Dr. Zdeněk Doležal, IPNP Supervisor's e-mail address: Zdenek.Dolezal@mff.cuni.cz Abstract: This doctoral thesis deals with two independent topics. In the first part we present a measurement of branching ratio(s) and time-dependent CP violation parame- ters in B0 (B± ) → ηcK0 S(K± ), ηc → p¯p. The values of CP violation parameters have been found as follows: sin 2φ1, denoted as an SCP parameter, equals: SCP = 0.68+0.38 −0.46±0.13syst, the direct CP violation parameter, denoted as an ACP , is: ACP = 0.00+0.23 −0.31 ± 0.08syst. These results have been obtained with the final data sample of 772×106 B ¯B pairs collected at Υ(4S) resonance with a Belle detector at the KEKB e+ e− asymmetric collider machine in Japan. In the second part, we present our approach to the Monte Carlo (MC) simula- tion of Belle II vertex detector and its response to high energy particles. Belle II represents an upgrade of current Belle experiment and its designed vertex detector will consist of 2 layers of Depfet pixel detectors (PXD) and 4 layers of double-sided silicon micro-strip detectors (SVD). The MC...

This study is engaged in express emergency methods to monitor internal contamination of people in the event of the radiological emergency.

This work deals with the automatic testing of an ultrasonic gas leak detector, which has to be tested during normal changes in the development phase. The reader will be acquainted with the basic principles of gas detection, design of the test product, software architecture its implementation. The following is a presentation of the application and instructions for writing tests. In this work, the Beaglebone Black development board with the Debian operating system is used as the core of the entire test product.

The master thesis presents an overview of face detection task in color, static images. Face detection term is posed in the context of various branches. Main concepts of face detection and also their relationships are described. Individual approaches are divided into groups and then define in turn. In the thesis is in detail described algorithm AdaBoost, which is selected on the basis of its properties. Especially speed of computation and good detection results are key features. In the scope of this work Viola-Jones detector was implemented. This detector was trained with face pictures from public accessible database. Combination of Viola-Jones detector with simple color detector is described. In the thesis is also presented experiment approach to facial features detection.

This thesis deals with real-time image processing including preprocessing, segmentation and classification of objects. On the basis of classification is determined rotation and position of objects. The aim of this project is to develop a modular application which will be able to monitor mobile units and determine their rotation and position in real time.

Master’s thesis belongs to the Cognitive radio network sphere. These networks utilize frequency spectrum more effectively than networks used in present radio communications. The Cognitive radio concept makes coexistence of classic and cognitive radio networks possible. Attention is aimed at spectrum sensing as the key task of the Cognitive radio. Main properties of the cyclostationary detector, as the detector, that reaches high probability of the detection at a very low signal to noise ratio with apriori knowledge of the transmitted signal's cyclic frequency, are examined in this paper. The OFDM signals, that inherit cyclostationarity from cyclic prefix, used in the real systems have been chosen for testing the properties of the detector. The influences of decimation and multipath propagation on the probability of detection are quantitatively expressed. The optimal values for the weights of the multicycle detector are determined.

Subject of this Diploma thesis is the design of metal detector and luggage X-ray screening. The thesis concerns with design of frame metal detector and luggage x-ray with focus on visual appeal, keeping of functional elements and concept of construction solution. Main objective is to find solution how to connect aesthetic, ergonomic and technical aspect. Complete analysis leads to design of metal detector and luggage X-ray screening. These appliances then appeal as compact system with uniform design. Also the machines can be used separately. Design of this system of appliances is solved through ergonomic, psychologic, technical and aesthetic aspects.

This thesis presents the Deriche edge detector as an interesting alternative to the commonly used edge detectors. The Deriche edge detector's design is presented to the reader as well as its strengths and weaknesses. Performance issues of the Deriche edge detector are described in comparison with the Canny edge detector together with recommendations for using the Deriche detector. Finally, edge detection quality of the Deriche edge detector is compared to the Canny edge detector using robust subjective evaluation method.

Charles University in Prague, Faculty of Pharmacy in Hradec Králové Department: Pharmaceutical Chemistry and Drug Control Candidate: Zbyněk Mrůzek Supervisor: prof. RNDr. Jiří Klimeš. CSc Consultant thesis: Ing. Pavel Blatný. Ph.D. Title of thesis: Determination of related substances in the dosage forms based on cyclosporine by HPLC with nitrogen specific chemiluminescence detection. Development of an HPLC method with chemiluminescent detection specific for nitrogen for related substances determination in cyclosporine final dosage forms is described in this work. The method is capable to determine cyclosporine impurities originated from cyclosporine substance and relevant degradation products except isocyclosporines. The method utilizes the stationary phase Zorbax SB-C18, particle size 1.8 µm, 150x2.1 mm and gradient elution at flow rate 0.15 ml.min-1 at column temperature 100řC. Mobile phases are Acetone: TBME: water: TFA (30: 5.5: 64.5: 0.01) and Acetone: TBME: water: TFA (49: 5.5: 45.5: 0.01). The work includes the verification of method validability in terms of specificity, linearity, limit of quantittion, accuracy, precision and robustness. The method can be used for determination of cyclosporine impurities in final dosage forms in pharmacetical QC laboratories. Keywords: cyclosporine....
