Fabrication of Nanowires into Porous Alumina by Electrolysis
Staňo, Michal ; Čechal, Jan (referee) ; Škoda, David (advisor)
This thesis deals with preparation of metal nanowires based on electrodeposition from aqua solution of metallic salts into porous dielectric aluminium oxide templates. The theoretical part covers various bottom-up methods of nanowire preparation using a template, electrochemistry and electrodeposition overview. The Experimental part is focused on the nanowire (Ag, Cu, Ni-H) preparation by means of direct current and alternating current electrodepositon and geometrical characterization of fabricated nanowires by scanning electron and atomic force microscopy. Defects of commercially available and prepared porous alumina templates are mentioned. Branching and coalescence of nanowires are briefly discussed as well.

Fabrication and Characterization of Templates for Fabrication of Nanowires
Lednický, Tomáš ; Čechal, Jan (referee) ; Škoda, David (advisor)
The bachelor thesis is focused on fabrication of alumina templates by anodization of pure aluminium. The theoretical part discusses the growing process of anodized oxide layers and its dependency on the crucial parameters (solutions, anodization voltage, time). The theoretical part is particularly based on literature retrieval. The experimental part is aimed to the fabrication of alumina membranes: the apparatus design, aluminium foils preparation, aluminium anodization, membrane modifications for next applications (nanowires deposition) and membrane characterization.

Fabrication of Nanostructures Using Atomic Force Microscopy
Doupal, Antonín ; Škoda, David (referee) ; Bartošík, Miroslav (advisor)
This bachelor thesis deals with fabrication of nanostructures using atomic force microscopy. The theoretical part gives a brief introduction into atomic force microscopy and local anodic oxidation and it is based on literature retrieval. The experimental part is concentrated on investigation of influence of operational parameters (tip-sample voltage, speed of the tip) on dimensions of LAO nanostructures on Si(111). Further the selective growth of cobalt and gallium on such oxide nanostructures is observed and analysed.

Characterization of 1-D Nanostructures by SPM Methods
Škoda, David ; Čech, Vladimír (referee) ; Pavlík, Jaroslav (referee) ; Dub, Petr (advisor)
The thesis is aimed at the characterization of carbon nanotubes and silver nanowires by Scanning Probe Microscopy, namely Scanning Tunneling Microscopy (STM), Atomic Force Microscopy (AFM), Conductive AFM (CAFM) and Scanning Near-Field Optical Microscopy (SNOM). Carbon nanotubes were analyzed by STM, AFM and CAFM microscopy. In a designed apparatus the silver nanowires were fabricated by template assisted deposition and were analyzed with respect to their geometry (AFM), local conductivity (CAFM) and optical properties (SNOM, microreflex spectroscopy). It was found that preferential type of carbon nanowires depends on the fabrication process. The measurements of local conductivity of the nanotubes revealed the similarity with the STM measurements. The AFM measurements of silver nanowires confirmed their growth inside the pores of polycarbonate template. Single nanowires exhibits the semiconducting behavior according to I--V measurement and localized plasmon resonances.

Monkey Bank Robbers
Škoda, Dominik ; Lidický, Bernard (advisor) ; Cibulka, Josef (referee)
The project concerns of creation of computer game inspirated by the game RoboRally. The program is based on Client-Server architecture and allowes players to play together via Internet. The application running on server manages individual games and takes care of synchronization between players. The program allowes to implement artificial inteligence which can join individual game with another players. Each player can create any map and play a game with any map. The project is designed for simple extension in future. The program is developed in JAVA language.

Simulink Block Library for LEGO NXT
Škoda, Dominik ; Bureš, Tomáš (advisor) ; Bulej, Lubomír (referee)
Simulink Block Library for LEGO NXT Abstract Dominik Škoda July 30, 2014 The goal of this work is to create a support for the LEGO NXT platform in Simulink development environment. Such support of the target platform already exists, but it suffers from several disadvantages. At first it is provided exclusively for Windows operating systems, and the implementation is closed, therefor neither extensible nor customizable. The main premise of this project is the support of Linux operating systems. The project is also opened to ensure the extensibility and customizability. The model-driven development of systems for the LEGO NXT platform using this project comprises the model testing in a simulation and code generation in Simulink environment by using its standard tools, and deployment of completed programs to target devices. The systems generated with the help of this project are categorized as real-time systems.
