Synthesis of electronically configurable filters with modern active elements
Hricko, Tomáš ; Šotner, Roman (referee) ; Langhammer, Lukáš (advisor)
This bachelor thesis is concerned of proposal electronically configurable filters. The first part describes the basic division of frequency of filters and working modes alongside with the principle of electronically configuration. All active elements used in the proposal of presented circuit solutions are defined in the second section. The third part consist of the design of three circuits of electronically configurable filters and comparison of theory with simulation results obtained from program OrCAD PSpice. The concluding part of the work compares the experimental results of the implemented filters with the PSpice simulations.

Laboratory exercises explaining the principles of network technologies and protocols
Hricko, Tomáš ; Jeřábek, Jan (referee) ; Langhammer, Lukáš (advisor)
The aim of this diploma thesis is to create two exercises for students. The first exercise is concerned with comparison of transport protocols TCP and UDP. The second exercise is concerned with comparison of routing protocols OSPF and RIP. The first part describes used simulation environment. The next part describes the operating system used in routers. The following part describes the procedure of installing virtual machines. The next part consists of theory of protocols TCP, UDP, OSPF and RIP. The last two chapters are the laboratory exercises.

Vliv různé intenzity probírky na přírůst v porostech týku (Tectona grandis) založeného ve sponu 1 x 1 m
Hricko, Tomáš
The aim of this work was to find out the effect of three different cultivation interventions on teak forest (Tectona grandis) based on Nicaragua plantations in an unusual spacing 1x1m and to determine which of these interventions have the best influence in terms of the growth of wood mass and consequent mechanical stability of the overgrown stands. A height and thickness measurement of trees in the area of interest was carried out in 2014-2017. It was always a series of three types of thinning (schematic with 75% reduction, schematic combination with positive selection with 45% reduction and individual negative trench with about 55% reduction, one control area was left without intervention) in three replicates for stands based on years 2006, 2007 and 2008. According to our results, the best intervention is those with 75 % of reduction.
