Controlling of camera
Tylš, Ladislav ; Valach, Soběslav (referee) ; Richter, Miloslav (advisor)
This thesis describes the principles of making application which is able to set and control camera. The first part describes basic camera connections and it explains definition and specification of camera’s features. The second part of my thesis describes implementation of application, which can use more cameras to image preview, image acquisition and to simply set of camera’s features. To implement the applications we can use MATLAB and C++BUILDER uses opencv libraries.

Pulse Oxymeter in LabVIEW
Synek, Josef ; Chmelař, Milan (referee) ; Čmiel, Vratislav (advisor)
One of the most important vital functions of the human body is providing sufficient oxygen to all its parts. Oxygen in the blood binds to hemoglobin and it is transported to tissues. Oxymetry is non-invasive method for measuring the amount of oxygen bound to hemoglobin. Oxygenated hemoglobin and deoxygenated have different absorption characteristics for light of different wavelengths. Therefore, pulse oxymetry transmits tissue with red and infrared light. Signal passing through the tissue is affected by the absorption properties of hemoglobin and heart pulse. These signals are measured and the ratio of their size allows us to calculate blood oxygen saturation.

Modern methods of reconstruction of saturated signals
Beránek, Šimon ; Smékal, Zdeněk (referee) ; Rajmic, Pavel (advisor)
This master's thesis deals with the problems of signal degradation caused by clipping and methods for its removal and signal restoration. Basics of mathematical formulations needed, signal processing and optimalization tasks are described. The goal of this thesis is the implementation of basic algorithms used for hard declipping and creating an audio database later used for testing these algorithms. These implementations are followed by modeling of soft clipping and later restored using the improved algorithms. The restorations are tested using the subjective hearing test MUSHRA and the results are statistically evaluated.

Social Need and Their Saturation in the Treatment of Stroke
ČERVENKOVÁ, Eva
Medical staff should not forget on meeting the needs of the patients. Stroke is a disease that changes a person's role in society. When the disease occurs to the disruption of social needs, and this may worsen the course of treatment. Inadequate satisfaction of social needs in time of illness can lead to impaired adaptation of the patient to the society. Objectives: to Map the way in which the medical staff monitors and saturates the social needs of the patient after a stroke. Research question: How general nurses monitor the social needs of the patient after a stroke? What social needs are most often represented? How nurses help influence the saturation of these needs?

Štítná žláza prasat
ŠTĚCHOVÁ, Petra
Thyroid gland is very important endocrine organ that interferes with a number of processes in the body. Sufficient iodine saturation of animals is essential for optimal production of thyroid hormones. The aim of the bachelor's thesis was to determine iodine supply of slaughter pigs and morphometric parameters of thyroid glands in selected individuals. The study included 27 castrated hybrids of Czech landrace and Pietrain. Iodine content in urine was determined using the Sandell - Kolthoff spectrophotometric method. Thyroid parameters were determined microscopically: length, width, outer and inner area of the follicles and thyrocyte height. The representation of individual size categories of follicles was also determined. The average content of urinary iodine in the observed group was 350.8+-184.3 ug/l, the maximum was 608 ug/l and the minimum was 76 ug/l. Optimally saturated with iodine was 44.44 % of individuals, 11.11 % had a deficiency and 44.44 % an excess of iodine. The average length of the thyroid follicle was 149.3+-64.8 um, width 105.9+-50.6 um, outer area 16810.6+-18030.0 um2, inner area 14318.4+-16985.2 um2 and thyrocyte height 6.2+-2.6 um. In the thyroid glands was 9.4 % small, 62.8 % medium and 27.8 % large follicles. In the selected group of individuals, the impact of different iodine saturation of animals on all monitored thyroid parameters was demonstrated.

Modern methods of reconstruction of saturated audio signals
Mikulášková, Aneta ; Mokrý, Ondřej (referee) ; Rajmic, Pavel (advisor)
This thesis presents a variety of soft clipping simulations and their respective de-clipping functions. A restoration method uses a Douglas-Rachford algorithm (already verified for hard de-clip). The algorithm is extended by inverse functions and simultaneous de-quantization is proposed. The simulations are applied to artificial signals, and audio samples, and the proposal is tested in the computing environment MATLAB. A restored signal is later evaluated by objective and subjective methods.

In vitro saturation study of 99mTc-HYNIC-ramucirumab on PC-3 cell line
Lach, František ; Bárta, Pavel (advisor) ; Smutná, Lucie (referee)
v anglickom jazyku Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biophysics and Physical Chemistry Student: František Lach Supervisor: Mgr. Pavel Bárta, PhD Consultant: Mgr. Lucie Hyršová Title of diploma thesis: In vitro saturation study of 99m Tc-HYNIC-ramucirumab on PC-3 cell line The number of malignant tumours in the population has increased in recent years. Due to the frequent serious sides effects of chemotherapeutic drugs on the whole organism, targeted antitumor therapy is at the forefront. Due to its specific effect on the regulatory and signal pathways of protein structures, monoclonal antibodies are used for the target anti-tumour therapy. The basic properties of the growing tumour include vasculogenesis (the ability to build new blood vessels from the endothelial precursors) and angiogenesis (the process of self-inducing formation of blood vessels). Endothelial tumour progenitors include vascular endothelial growth factor (VEGF). VEGF activates its biological activity by binding to its transmembrane tyrosine-kinase receptors VEGFR. Indeed, the inhibition of the vascular endothelial factor receptors is the target of some monoclonal antibodies. Ramucirumab is a monoclonal antibody that selectively inhibits VEGF receptor type 2 (VEGFR-2) and thereby...

Channel Merging Techniques for improving Dynamic Range of ± 10 V Signal Chain Channel
Dušek, Samuel ; Prokop, Roman (referee) ; Kledrowetz, Vilém (advisor)
Cílem této diplomové práce je změřit a vyhodnotit parametry techniky slučování kanálů, která je momentálně implementována v součástce AD7606C firmy Analog Devices. Poté, na základě výsledků z měření, navrhnout a odsimulovat několik možností, pomocí kterých by tato technika mohla dosahovat vyšších hodnot dynamického rozsahu a celkového harmonického zkreslení. V průběhů práce bylo zjištěno, že pomocí zvýšení zesílení kanálu s nižším rozsahem společně se snížením mezní frekvence celého signálového řetězce může tato technika dosahovat až 118.6 dB dynamického rozsahu, což je o 3.6 dB více, než bylo změřeno na AD7606C. Dále také bylo zjištěno, že pomocí jednoduchého algoritmu implementovaného v logickém bloku, je možné dosáhnout imunity vůči hodnotě externího rezistoru, který zákazníci používají jako součást anti-aliasingového filtru.

Saturace koní jodem v Jižních Čechách
SLAVÍKOVÁ, Sofia
The main aim of this thesis was to evaluate the current state of iodine levels in horses from selected farms in South Bohemia. Out of the sample group, no animal with iodine deficiency was detected. Additional objective of this thesis was to assess whether selected horse owners supplement their horses with iodine and what form of supplementation they choose.
