Schoof's algorithm for Weierstrass curves
Zvoníček, Václav ; Drápal, Aleš (advisor) ; Mareš, Martin (referee)
Schoof's algorithm is the starting point for the most efficient methods for determining the number of rational points on an elliptic curve defined over a finite field. The goal of this thesis is to introduce the subject of elliptic curves, with the emphasis on Weierstrass curves over a finite field, to describe Schoof's algorithm and its time complexity, and, finally, to implement it in C++ with the support of NTL. The implementation provides a user with a reasonably fast utility for determining the order of Weierstrass curves over finite fields of size up to 128 bits. 1

Noradrenalin in theory and practice
Literová, Hedvika ; Zvoníček, Václav (advisor) ; Kušnieriková, Anna (referee)
This thesis deals with the administration of noradrenaline with emphasis on the issue of infusion therapy in critical care. The aim of the conducted study was to map the method of dilution and handling of noradrenaline within the Fakultní nemocnice Královské Vinohrady. The evaluation was based on a questionnaire survey and the results show that the method of dilution and handling of noradrenaline is not unified within the hospital. Based on the results of the work, the author recommends standardization of dilution of noradrenaline, it's handling and syringe labelling.

The effect of tracheal tube clamping and its influence on lung ventilation physiology in critically ill patients
Minaříková, Petronela ; Zvoníček, Václav (advisor) ; Dostál, Pavel (referee)
v AJ The Master's thesis explores the effect of endotracheal tube (ETT) clamping on the physiology of lung ventilation in critically ill patients. In the theoretical part, I first discuss artificial pulmonary ventilation and the reasons for its use, describing the ventilation circuit, its composition and the possibilities for the involvement of its components, which are the reason for its periprocedural disconnection in nursing care. I explain in more detail the recruitment/derecruitment issues and in a separate chapter I explain the principles and use of positive end-expiratory pressure (PEEP). Finally, I explain the electrical impedance tomography (EIT) method used. The main aim of the research was to evaluate the effect of EIT clamping in intubated patients during short-term periprocedural procedures as well as its influence on the development of atelectasis and intraluminal shunt. Four patients requiring connection to artificial pulmonary ventilation were included in the study population, from whom a total of eight measurements were obtained by EIT. Ventilation values were read during data recovery from arterial and venous Astrup scores collected before and after intervention. The results show that clamping the ETT during periprocedural disconnection of the ventilation circuit ensures a smaller...
