Utilization of aquarium in the biology education
Špůrová, Hana ; Hanel, Lubomír (advisor) ; Andreska, Jan (referee)
This thesis focuses on the use of freshwater animals in biology lessons. It especially provides detailed instructions for school experiments and observations of these animals, which can be bred in a freshwater aquarium at school. Manuals have worksheets for pupils and are anter keys. Each worksheet has got guidance for teachers, which contains specific instructions for the preparation of observation and experimentation and also gives some additional information. Individual worksheets are focused on representatives of cold water and tropical freshwater fish, shrimp and crayfish. A considerable part of the worksheets is devoted to our invertebrates, which can be caught in nature, and placed into the aquarium for a limited period, so there we can see the experiments and observations of some aquatic larvae of insects, flatworms, bugs, beetles, molluscs, annelids and arthropods. It also includes information about the various representatives used in the worksheets, such as a brief description of the animal and its demands for breeding. There are also instructions on how to obtain these animals. This thesis also contains practical manuals onwhere to place the aquarium in the classroom and how to manage and maintain it because this work is conceived as a handbook for teachers of biology, who have no...

Vybrané aspekty vlivu bezobratlých herbivorů na složení travinného společenstva
HRUBÁ, Karolína
The first part of my thesis is focused on observation of the leaf damage by invertebrate herbivores during season. I examined how the selected traits affect the palatability of plant species. In the next project, I investigated the effect of herbivory and gaps on seedling establishment. And finally, in the last part, I studied the effect of herbivory of terrestrial gastropods on competitive relationships among selected species.

Design of a complex automated system for aquarists
Hedvíček, Michal ; Kunz, Jan (referee) ; Uher, Miroslav (advisor)
Thesis deals with the theoretical design of an automatic control system for the aquarium and following simulation software environment Proteus ISIS. Due to simulation program can verify the behavior of the microprocessor in the specified functions, the correctness of electrical connections and errors in source code. The second part is analysis of commercial systems, their characteristics and applications. Apart from available commercial systems, there is a basic overview of commonly used peripherals in the aquarium, including their comparison and evaluation. Furthermore, the implementation of a complex system is done and the procedures and methods needed to set up the system are described. This topic also deals with cooling and reliability tests.

PH controller for aquarium
Dvořák, Jan ; Fedra, Zbyněk (referee) ; Šebesta, Jiří (advisor)
This bachelor’s thesis deals with the system which is designed as a pH regulator for aquarium water. The first and second chapter are aims to the basic requirements and possibilities on controlling of the potential of hydrogen in water. Main methods of the pH measuring, its controlling and regulation are included. The third chapter presents a design of the pH regulator system. The practical and software solution of this project is presented in the fourth and fifth chapter. There are described in detail the main blocks of the pH regulator - amplifier, galvanic isolator and output power stage. The results of the testing and measuring of the designed subsystems are introduced in the last part of the work.

Automated environmental support system for aquarium
Slavotínek, Jan ; Honec, Peter (referee) ; Petyovský, Petr (advisor)
The thesis is devoted to analysis of parameters and processes in aquarium, in order to design system for control, regulation and monitoring the most important of them. In theoretical part of thesis are defined terms and basic knowledge necessary for successful analysis, some of them are marginally reaching into different science discipline (biology, zoology, engineering, etc.). The thesis contains a part focused on analysis of common operation and requirements connected with prospering aquarium. In this part are determined common ranges of values, limitations and requirements on safety operation of system, if necessary. Following chapters of thesis are devoted to design hardware and software solution of particular system, ensuring control, regulation and monitoring of variables and processes determined as critical.

Microcontroller based aquarium control system
Gothard, Adolf ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
This bachelor‘s thesis deals with design of automatic aquarium control system, equipped with microcontroller AT89C51ED2 and simple user interface. After opening introduction to systems, usually used for aquarium automation, there is described design of such device. First, it is selection of components and concept of their electrical connections. Next part is devoted to realisation and found problems and their removing. The last part is devoted to design and creation of program equipment of the control system. This part shows basic principles of control program and structure of it’s main parts. Low-level functions for communication with peripheral devices are also described.

The system for regulation of the environmental conditions in the aquariums
Janda, Josef ; Jaroš, David (referee) ; Macháň, Ladislav (advisor)
This thesis project describes the design and construction of an automated system for maintaining live conditions in aquarium. The main purpose of the system is to automate certain procedures and to ensure control of important environmental parameters of artificial breeding of aquarium animals and plants. The device regulates lighting, temperature, CO2 concentration and other parameters. The LCD with touch screen is used to system control and to display measured values.
