Dynamic electroneurostimulation and electrical properties of skin
Špeta, Marek ; Dvořák, Petr (referee) ; Špinka, Jiří (advisor)
The focus of this diploma thesis is on theoretical basics of dynamic electroneurostimulation, which is an effect of electrical signal on acupuncture points of skin. This technology is used in devices made by russian DiaDENS company. Practical part of this thesis covers design of human skin impedance model. Especially derivation from three-element Cole-Cole model. Elementary, there is design of equivalent circuit of constant phase element and its incorporation into circuit. Then this circuit is designed, simulated and produced. Resulting product is used as a load to measure the characteristics of the DiaDENS device.

Software implementation of the subjective assessments of sound quality
Špeta, Marek ; Balík, Miroslav (referee) ; Rášo, Ondřej (advisor)
The focus of this diploma thesis is on methods for the subjective assessment of sound quality according to recommandations given by International Telecommunication Union ITU. The thesis is thematically divided into four parts. The first part is an interpretation of methods based on internationally accepted standards (method of small impairments, MUSHRA, general methods). The second part describes the functional blocks of application developed for this thesis in LabVIEW enviroment. Next part explains its practical application, especially its running possibilities. The last part describes a listening experiment, aim of which was to verify the application's features and to compare the results of the subjective method used in the experiment with the results of the objective method PEAQ.

Interactive map resources on the Internet
Špeta, Marek ; Lambertová, Petra (referee) ; Koutný, Martin (advisor)
The objective of this thesis gives an overview of available technologies used to work with map resources on the Internet. The thesis also contains overview of different input data formats and procedures for obtaining maps. Practical part is focused on designing and implementing web applications using map resources, puts the emphasis on the modularity and simplicity of data entry and data. The implementation uses the PHP scripting language, MySQL database and the additional functions uses Ajax technology and JavaScript language.
