Laser Doppler anemometry
Osička, Tomáš ; Lízal, František (referee) ; Jedelský, Jan (advisor)
This bachelor thesis deals with laser Doppler anemometry (LDA). It is a modern, non-intrusive flow measurement technique. The work deals with theoretical principles and components of the method. The experimental part is devoted to setting of the system. Vector plot and profile plot display the measurement results.

Flow visualization methods
Ďurdina, Lukáš ; Jedelský, Jan (referee) ; Lízal, František (advisor)
ĎURDINA, L. Flow visualization methods. Brno: Brno University of Technology, Faculty of Mechanical Engineering, 2010. 45 p. Thesis supervisor Ing. František Lízal. This thesis deals with fluid flow visualization methods with respect to their practical application possibilities. Chronological description of the historically valuable visualization experiments emphasises the role of visualization in the experimental fluid mechanics. A brief characteristic of the flow field contains mathematical description of the objects, which can be visualized. Visualization methods are divided into experimental and computer aided methods. Individual methods are ordered subsequently beginning with those with lowest requirements for equipment to the more sophisticated methods. Various techniques, which provide qualitative and quantitative description of the tested gas or liquid flow, are described. The overview for the choice of methods for various applications sums up the important facts from previous chapters. Description of a simple helium bubble flow visualization experiment realized in a lab can be found at the end of the thesis.

The methodology for visualization of the internal structure of the painting using novel x-ray based methods
Hradilová, Janka ; Hradil, David ; Trmalová, Olga ; Žemlička, Jan
Aim of the methodology is to involve the newly tested a newly developed methods, which allow displaying an internal structure of a painting, into the routine conservation/restoration research. The methodology is yet specifically focused only on methods using X-rays, i.e. X-ray radiography (XRR) and X-ray fluorescence (XRF) (including macroscopic XRF scanning). The methodology includes testing the radiographic equipment with pixel detectors, which has been newly developed within the project, and assesses its contribution to the practical survey of painting techniques reflecting its exceptional spatial resolution, materials sensitivity and mobility.

Comparison of devices and microscopical assesment differential count of leukocytes
NETREFOVÁ, Veronika
This thesis deals with methods of determination of differential count of leukocytes and their positives and negatives. No wonder that nowadays modern haematology analyzers have been used for determination of differential count of leukocytes due to technical progress, however manual assesment by microscope keep still being a basic element of good work in a haematology laboratory. In the practical part I will describe single work procedures and these methods will be then compared according to the observed results. The Coulter LH 750 analyzer by Beckman Coulter Inc. based on the principle of electric impedance has been used in Nemocnice České Budějovice a.s. for automatic assesment of differential count of leukocytes. In case of the microscopic assesment a blood film is made which is then stained by Pappenheim method with May - Grünwald and Giemsa - Romanovsky colours. Then I will try to suggest an optimization for current investigation of the complete blood picture.
