Assessment of the intake of vitamins in lactating women
Burešová, Nicole ; Kovařík, Miroslav (advisor) ; Kudláčková, Zděnka (referee)
Charles University, Faculty of Pharmacy in Hradec Králové Department: Biological and Medical Sciences Tutor: PharmDr. Miroslav Kovařík, Ph.D. Student: Nicole Burešová Title of thesis: Assessment of vitamin intake in lactating women Background: This theses focus to evaluate vitamins intake of lactating women. A sufficient vitamins intake is very important for both mothers and their infants. The aim of this theses was an assessment of lactating women vitamins intake without and including vitamins supplementation. It was determined whether the intake of individual vitamins changed with the duration of lactation, and then the average intake values were compared with the recommended daily allowances (RDA). Finally, the proportion of women who did not meet the RDA was evaluated. Methods: Data collection for this study took place in 2021-2022. There were eleven lactating women between years of age 29 and 40 involved. These women underwent medical examinations at laboratory four times after the delivery - during L1 lactation period (3-4 weeks after the delivery), L2 period (3 months after the delivery), L3 period (6 months after the delivery) and finally L4 period (9 months after the delivery). During the L1 and L2 periods the questionnaires were submitted by 9 women, during L3 period by 10 women and...

Creating a VPN Access Point on Raspberry Pi
Kovařík, Martin ; Hájek, Jaroslav (referee) ; Benedikt, Jan (advisor)
This bachelor thesis deals with creating a virtual private network (VPN) access point on a single-board Raspberry Pi computer. The theoretical part describes the principle of VPN, the most common tunneling protocols and the Raspberry Pi computer in general with its various generations and models. Selected protocols are implemented on the Raspberry Pi and their hardware load, response and throughput are measured. The stability of the protocols is tested and reliability evaluated.

Coilgun
Kovařík, Martin ; Pavlík, Michal (referee) ; Šteffan, Pavel (advisor)
This bachelor’s thesis describes the design and construction of electromagnetic gun for testing projectiles from different ferromagnetic materials with maximal power 19 J. Conventional projectile propulsion mechanisms include the use of compressed air or explosion which places theoretical limits on the maximum muzzle velocity limited by laws of thermodynamics. The electromagnetic coil gun, explores the use of electromagnetism in accelerating projectiles which offers a much higher theoretical limit on muzzle velocity. In addition of an electromagnetic acceleration is possible to regulate output velocity/energy of projectile, and acceleration applied on projectile.

Antispam software plugin for e-mail filtering based on geolocation of the sender
Kovařík, Martin ; Komosný, Dan (referee) ; Caha, Tomáš (advisor)
This thesis deals with the creation of a module for antispam software providing email filtering using sender geolocation. The theoretical part of the thesis describes spam in general and the threats that spread through email communication, such as social engineering and malware. Then the principle of email and email headers, email filters and their methods to filter messages are described and lastly IP geolocation and machine location methods are described.The created filtering module Geolock was designed for the SpamAssassin antispam software and uses the IP2Location geolocation database. The embedding of the module into SpamAssassin is shown and the module itself and its different parts are described. The module is tested on a dataset and a real-life application is outlined. The Geolock module is published on GitHub under the MIT license (https://github.com/MartinKovarik/Geolock).

Library for Multiplatform Development of Mobile Apps
Kovařík, Michal ; Sochor, Jakub (referee) ; Herout, Adam (advisor)
This thesis addresses the issues when developing mobile applications for multiple operating systems and development environments, with the target being to create the ideal user interface library. A framework for HTML app development has been designed and implemented that is built on top of modern web standards, allowing the developer to create applications with a single codebase that will, when deployed, intelligently adapt to the device and operating system that they are being run on. Released as an open-source project and currently supporting Windows 10, Android, Chrome OS and Web. Flexus, a framework for building user interfaces, is in live use and active development.

Voltage transformer
Kovařík, Martin ; Huzlík, Rostislav (referee) ; Ondrůšek, Čestmír (advisor)
This bachelor´s thesis focuses on the elements of equivalent circuit parameters of voltage instrument transformer TJC 7-G from the portfolio of ABB. Main focus is placed on correct identification of the leakage reactance of primary and secondary winding, which are used for correct settlement of protections. The measurement is done by using methods of measurement of transformer without load and with short circuited secondary terminal. The values are measured for different frequency levels, in order to determine precisely all the parameters. The theoretical part describes the use of instrument transformers, theoretical creation of equivalent circuit and parameters which affects the accuracy class. The conclusion contains the evaluation of different methods for determining the elements of the equivalent circuit and with its final assembly.
