Initialization for optimization of real world vehicle routing problem
Volf, Robin ; Klhůfek, Jan (referee) ; Sedlák, David (advisor)
The goal of this work is to optimize the initialization phase in solving the rich vehicle routing problem on a specific dataset which comes from a czech logistics company's data. This dataset has characteristics of VRPTW, VRPSPD and HFVRP. A modified cheapest insertion heuristic was chosen for the solution. Cost calculation consists of six partial costs which reflect individual constraints. Proposed heuristic is able to solve the instances in a matter of few seconds. Construction heuristic which generates valid solutions in short time enables more effective optimization in latter parts of solution.

Preamplifier for guitar pickups
Raimr, Jakub ; Balík, Miroslav (referee) ; Hanák, Pavel (advisor)
This thesis focuses on design and realization of a 4-channel preamplifier for guitar pickups. The preamplifier is determined to measure balanced spectral characteristics of all four pickups at the same time. The thesis composes of a theoretical introduction about pickups, installation of pickups in the acoustic guitar, measuring spectral characteristics of pickups, design of the preamplifier on a both-sided PCB, realization of the PCB and final measurement using the finished preamplifier. The final product will serve as a~laboratory exercise in the course Hudební elektronika.

Electric Volin with MIDI Output
Spilka, Benedikt ; Vrba, Kamil (referee) ; Schimmel, Jiří (advisor)
The main aim of this diploma thesis is to design and to construct a electric violin with MIDI output. This thesis include design and conctruction of violin pickup, violin electronic and software for translation of sound into MIDI messages. design of the instrument´s body is presented at the end of the thesis. Violin electronic include circuits for filtration, amplification, processing and AD/DA conversion of audio siganl. Software for MIDI transfer recognizes notes and translates them to MIDI messages.

Experimental Electro-Mechanical Musical String Instrument
Blasche, Ondřej ; Mojdl, Edgar (referee) ; Dlouhý, Dan (advisor)
The goal of this thesis is to design and build stringed mechanical electrphone with unusual sound characteristics. The end product is an instrument devided into three sections with specific options of sound creation, able to be both plucked and played with a bow. Thesis utilizes knowledge of electric guitar construction and their sound pickup methods. It also deals with experimentation in the field of strig instruments and their development.
