Fusion of Sensors for Autonomous UAV Navigation
Semerád, Jakub ; Janoušek, Jiří
This paper describes an UAV equipped with a control computer, flight controller, Lidar and depth camera. The UAV telemetrically communicates via the Mavlink communication protocol with a ground station where actual data can be monitored, or the drone's mission can be interfered from there. This whole system produces a 2D map and a 3D color map in real time. This data can be used for obstacle avoidance, object recognition, mapping unknown environments, tracking moving objects and autonomous navigation.

The toxicity of vitamin D
Drouliskou, Eleftheria ; Mladěnka, Přemysl (advisor) ; Janoušek, Jiří (referee)
Vitamin D has essential role in skeletal health, however studies over the recent years have outlined its implication in many other physiological functions. The importance of vitamin D for health has, on one hand, raised needs for supplementation but may, on the other hand, lead to excessive administration. Vitamin D toxicity or hypervitaminosis D due to excess of vitamin D is a medical condition manifested mainly as hypercalcemia, with mostly gastrointestinal and neuropsychiatric symptoms. Long-term administration of large doses of vitamin D can result in vascular calcification and hence by associated with a cardiovascular risk. Hypervitaminosis D is extremely rare likely due to high therapeutic index of vitamin D. The clinical research shows an administration of 10.000 IU/day of vitamin D, which meets the criteria for the tolerable upper intake level, even for extended period, is probably not associated with adverse effects in almost all individuals in general population. However there are case studies globally showing vitamin D toxicity can occur due to misuse of over-the-counter vitamin D supplements, inappropriate prescribing or uncontrolled administration of high dose unlicensed preparations.

Fusion of drone sensors for motion planning
Semerád, Jakub ; Novotný, Josef (referee) ; Janoušek, Jiří (advisor)
This bachelor thesis deals with drone flight planning in an unknown environment. In order for a drone to be able to perceive its environment, it must be equipped with the necessary sensory equipment. This thesis discusses possible sensor equipment suitable for flight coordination and collision avoidance. Also, software for sensor data processing and drone motion planning are described and used here. LiDAR and depth camera were used for the experiment in this thesis. In the experiment the data from both sensors are fused together through ROS software and displayed in RViz simulation environment. This data are suitable for subsequent use in drone motion planning and collision avoidance.

Communication network for a swarm of unmanned aerial vehicles
Rajm, Jan ; Götthans, Tomáš (referee) ; Janoušek, Jiří (advisor)
This bachelor thesis deals with creation of robust communication network used within swarm of unmanned aerial vehicles and its testing. In the first part, network requirements are presented and selected communication standards capable of transmitting telemetry data are described. The second part describes the software needed for telemetry data transmission and drone control. The third part presents designed communication network for a swarm of drones. Capabilities and differences between the designed network and networks based on other network technologies are presented. Also, the creation procedure of the designed network is described. The fourth part deals with a testing and an evaluation of results.

Janoušek, Jiří ; Hošková, Blanka (advisor) ; Bartůňková, Staša (referee)
Název práce: Pohybové aktivity při rekondičních pobytech a jejich význam s diagnózou DIABETES MELLITUS Title: Physical activities at the stay at health recondition camp with the diagnosis Diabetes mellitus Cíle práce: Zmapovat vhodné pohybové aktivity pfi rekondičních pobytech lidí s diagnózou Diabetes Mellitus, zpracovat model rekondičního pobytu a jejich popis, členění, a program v průběhu rekondičního pobytu, který bude možným vodítkem k realizaci rekondičních pobytů s diabetiky z pohledu pohybových aktivit lékařům, zdravotním sestrám a dalším zdravotnickým pracovníkům, kteří o organizaci takovýchto aktivit uvažují nebo je plánují. Současně si klade za cíl upozornit na rizika pohybových aktivit u diabetiků a nabídnout konkrétní plán pohybové části takových pobytů při dosažení pozitivního vlivu pohybu na organizmus diabetiků. Současně si klade za cíl ověřit vliv rekondičních pobytů na dlouhodobou kompenzaci diabetiků a potvrdit tak jejich význam pro kvalitu jejich života. Metody: Byla provedena studie, kde kromě vlastního sledování, byla použita i metoda vyšetření a pozorování a anketa vlivu pohybových aktivit na kompenzaci diabetika. Dále bylo provedeno hodnocení glykovaného hemoglobinu před rekondičními pobyty a po nich s odstupem 6i a 12i měsíců. Výsledky: Při působení vybraných pohybových...

SPE Utilization in Analysis of Benzimidazoles I
Janoušek, Jiří ; Kubíček, Vladimír (advisor) ; Drastík, Martin (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biophysics and Physical Chemistry Candidate: Jiří Janoušek Supervisor: Ing. Vladimír Kubíček, CSc. Title of diploma thesis: Use of SPE in analysis of benzimidazoles I Anthelmintic resistance in parasitic worms is an up-to-date topic. In order to combat this resistance we need to find proper analytic methods of its monitoring. The goal of this thesis is to find a suitable method of benzimidazole extraction, using a solid-phase extraction. During the experiments I used SPE tubes Supelco DSC-C8 (1ml, 100mg). In my thesis I tested the influence of pH and composition of elution agents on recovery of extraction. I performed the extraction in acid, neutral and basic environment. Elution agents consisted of a mixture of acetonitrile and polar phase, with four different mixing ratios. The best results were obtained during extraction in basic environment. For SPE tubes DSC-C8 the most suitable elution agent consisted of 4 parts of acetonitrile and 6 parts of 10% ammonia solution. Keywords: benzimidazoles, flubendazole, mebendazole, solid-phase extraction, resistance, anthelmintics

Study of the effect of the amount of chelating agent addition on the result of monoclonal antibody conjugation
Janečková, Adriana ; Bárta, Pavel (advisor) ; Janoušek, Jiří (referee)
v anglickém jazyce Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology and Toxicology Student: Mgr. Adriana Janečková Supervisor: Mgr. Pavel Bárta, Ph.D. Title of rigorosum thesis: Study of the effect of the amount of chelating agent addition on the result of monoclonal antibody conjugation Monoclonal antibodies have become the important tool not only for the therapy, but also for the diagnosis of the infectious, autoimmune or cancer diseases in the last few decades. In addition to their own therapeutic effect, monoclonal antibodies are used as vectors for biological substances with therapeutical and diagnostic importance. Besides bacterial and plant toxins, monoclonal antibodies are also effective in their capability to deliver radionuclides to the site of their specific binding, i.e. the antigen against which they were prepared. The so called radioimmunoconjugates are then successfully used in radiodiagnostic and radiotherapeutical field. Radionuclides can be bound to antibody molecule either directly in the case of halogenation or indirectly. The latter method is the most common one due to a greater stability and suitability for more radionuclides, which can be transported by antibodies. Substances that allow the radionuclide biding to the monoclonal antibody...
