Detector of bubbles in blood
Foltýn, Vojtěch ; Sekora, Jiří (referee) ; Rozman, Jiří (advisor)
ABSTRAKT This thesis is the theoretical part deals with various ways of cleansing the blood, with a focus on hem dialysis. Describes the technical solution and monitor the dialysis flow diagram of blood and dialysate. The paper describes various solutions to detect bubbles in the blood and their advantages and disadvantages. Based on the best method of detection are designed detector bubbles. Working in the practical part contains a proposal detector set for venous diameter of 20 mm. Equipment to detect bubbles allows for connection to a blood pump discontinue its activities. Output works are drawing diagrams, printed circuit board design and implementation of graphs circuits.

Thermoacoustic measurement of ultrasonic power
Vysoudil, Ladislav ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
The assignment of this work is to suggest structural design of thermoacoustic sensor and experimentally verify his function for testing intensity of ultrasound diagnostic systems. Then the measured results are compared with measurement by the hydrophone in ultrasonic measuring tank. Opening part of this work is focused on functional description of sensors and their construction, including functional description and construction of hydrophone. The rest of the work deals with project of thermoacoustic sensor and measuring with sensor and hydrophone and evaluation results of measurement. Intention of this work is to verify the correct function of designed thermoacoustic sensor with the help of comparison measurement with hydrophone.

Doppler blood flow detector
Klügl, Jan ; Čech, Petr (referee) ; Rozman, Jiří (advisor)
This bachelor's thesis is engage in suggestion of nondirection doppler blood flow detector with unmodulated carrying wave. At first the thesis describes indicator's principle of working and mention the systemic proposal for working frequency and intensity of ultrasound. Later in detail describes individual blocks, which are the detector consist of. At every block of system is mentioned the diagram of connection and values of components, which are ascertained from calculation, simulation and recommendation of producer.

Model nonlinear effect in ultrasound fields
Kulík, Tomáš ; Čech, Petr (referee) ; Rozman, Jiří (advisor)
The main topic of this diploma thesis is the modeling of nonlinear effects in ultrasonic fields. The work deals with application of finite difference method (FDTD) on the Westervelt equation and the subsequent creation of the model of ultrasonic fields in MATLAB. This thesis also includes theoretical analysis of ultra-acoustic and technical aspects of diagnostic ultrasonography. In addition, this document includes verification of theoretical assumptions by using created model.

Elektromagnetic field mapping in tissue
Port, Martin ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
This thesis is an introduction to the modeling of electromagnetic fields in the tissue and is focused on the knowledge of electromagnetic field theory. Maxwell's equations and their solutions are described the spread of plane waves in the environment. It also discusses the exposure limit values of specific absorbed power and hygienic limits based on the standards in force in the Czech Republic on health protection against nonionizing radiation in accordance with Government Regulation No. 106/2010 Coll. It also deals with the software interface in COMSOL Multiphysics 4.2 for solving physical modeling and simulation. There is mention of the RF module, which is used for modeling. Work mentions in detail about the menu of the program and the most important part - the Model Builder.

Chart of electromagnetic fields in GIS
Brachtl, Martin ; Bubník, Karel (referee) ; Rozman, Jiří (advisor)
The main goal in this bachelor thesis was to study the existence of electromagnetic fields in enviroment, and to study hygienic regulations. Then, to study functions of measurment system EMR-30 and to study UI of geographic information system ArcView and it´s abilities for data processing. Measurement of electromagnetic fields was carried out in the neighborhood of campus Pod Palackeho vrchem. For processing the measured data, creating maps and subsequent analysis were used programs ArcMap 10.1, ArcScene 10.1 and add-ons.

The Da Vinci Robotic Surgeon Hand Control System
Jakubík, Juraj ; Rozman, Jiří (referee) ; Sekora, Jiří (advisor)
This bachelor thesis deals with the design of the control system of the Da Vinci robotic hand made by american company Intuitive Surgical. The initial draft consists of linking with the program for control bitword generation in the LabVIEW environment and subsequent execution of movement using stepper motors with the Arduino microcontroller. The resulting design is using servos controlled by analog manipulators connected directly to the microcontroller. Treatment of border position control and slip is considered within both control systems.

Mapping of electromagnetic fields in GIS
Kačmařík, Ivo ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
The aim of this Master’s Thesis was mapping of electromagnetic fields and processing of measured data using ArcView 9.2 and its extensions. Software ArcView 9.2 with extensions was provided by university to create this Master’s Thesis. Maps of electromagnetic fields are created from measured data in the neighborhood of the faculty building. Measurement of geographic position of measuring points is realized by GPS. For creation of maps and further analysis in ArcView, ArcGIS extensions - Spatial Analyst, Geostatistical Analyst and 3D Analyst were used.
