Experimental Software Musical Instrument on Android Platform Combining Sampler, Synthesizer and Sequencer
Kučera, Karel ; Kavan, Jan (referee) ; Dlouhý, Dan (advisor)
The aim of this bachelor thesis is the realization of the application as an experimental software musical instrument on the Android platform. The implementation is partly based on the draft elaborated in semester work. The application is designed for tablets and smartphones. It combines functions of sampler, sequencer and synthesizer and contains built-in effects. With this features, it is possible to create new sounds, sequantions and songs. The applications is programmed by visual programing language Pure Data. The graphic interface is created by the MobMuPlat platform. The thesis is consists of three parts. The first part is a theoretical introduction, where are discussed, the theory of digital audio signal processing, principles and types of sound signal synthesis, effects and electronic instruments. Furthermore, the Pure Data and MobMuPlat platform features. The second part is an updated design of the graphical interface and there are discussed the functions of individual graphic elements. The third part describes implementation of the application by Pure Data

Experimental Hardware Musical Instrument, Converting Data from Sensors to Selected Musical Parameters
Šindler, Stanislav ; Kavan, Jan (referee) ; Dlouhý, Dan (advisor)
Abstract Aim of this thesis is to documentate theoretical and practical process of designing digital hardware syntetizer using Teensy microcontroler and add-on bus Teensy Audio Shield, with the help of Audio System Design Tool. Software for this synthesiser Product of this thesis will be complete device with user interface realized with rotational knobs, buttons and display unit. Also a removable module measuring temperature, intensity of light, and humidity, which will change user specified sound parameters, will be designed and constructed.

Design of Net-Based Virtual Collaborative Musical Instrument
Liudkevich, Denis ; Kiska, Tomáš (referee) ; Kavan, Jan (advisor)
The aim of this work was to create an online platform for multi-user sound creation with original sound synthesis tools. The educational context of the application was also taken into account by hiding the controls of the sound parameters behind the subconsciously known physical phenomena and the game form of the application. A substantial part of the logic and all graphics of the instruments is written in the JavaScript programming language and its library p5.js. It is located on the client side and communicates with the Node.js-based server via a web socket. The audio part is on another server in the SuperCollider environment, it is transmitted via IceCast and communicates with the main OSC message server. The application contains 3 instruments for generating sounds and one effects module. Each instrument is designed for multiple users and requires their cooperation. Acceptable transmission speeds and minimum computational demands have been achieved by optimizing the instrument's internal algorithms, the way in which the graphic content is displayed and the appropriate routing of the individual sound modules. The sound is specific for each instrument. The instruments in the application are tuned and designed so that the user can both achieve interesting sound results himself and play his role as a whole with others. Methods such as granular synthesis, chaotic oscillators, string instrument modeling, filter combinations, and so on are used to generate sound. Great emphasis in the development of the application was placed on the separation of roles, simultaneous control of one instrument by several players and communication of users through playing the instruments and text expression - chat. An important part is also a block for displaying descriptive information.

Experimental Software Musical Instrument on Android Platform with Ability to Control Parameters by Moving Phone
Barák, Filip ; Kavan, Jan (referee) ; Dlouhý, Dan (advisor)
The purpose of this thesis is to create an application on the Android platform, which is characterized by an unconventional way of controlling the main melodic signal – by moving the phone. At the same time, the application allows you to edit the audio parameters on your phone's display. Another important feature is the ability to compose and later play chords, or other simple harmonies. The application design is preceded by a theoretical introduction, where I briefly analyze the musical terms and parameters of the application that I developed in the Android studio, Java language. Furthermore, I mention the actual methods of application implementation including code samples.

Holocene history of Arctic lakes
Roman, Matěj ; Nývlt, Daniel (advisor) ; Kavan, Jan (referee)
Holocene history of Arctic lakes Abstract Palaeolimnology in the Arctic has achieved a considerable progress in the last decades. The Arctic has changed markedly since the Last Glacial and glacier retreats caused formation of a great number of diverse lake types. Lakes of glacial origin, thermokarst lakes, fluvial lakes and lakes on raised beaches occur most often here. Palaeolimnological methods applied to the high latitude areas are used for the study of the history of individual lakes. Methods of correlation of sedimentary cores and basic interpretation of proxy records such as magnetic susceptibility, diatom biostratigraphy and content of carbon and sulphur were applied on sediments of Garmaksla Lake, Svalbard Archipelago. Climatic and ecological shifts including the Little Ice Age termination and recent warming were registered in proxy values. Keywords: lakes, palaeolimnology, palaeoclimatology, environmental changes, Holocene, Arctic

Patency of dialysis fistulas in patients undergoing vascular interventional procedures.
Kaván, Jan ; Lambert, Lukáš (advisor) ; Chochola, Miroslav (referee) ; Beran, Jan (referee)
Purpose. The primary objective was to compare primary and secondary patency, number of percutaneous transluminal angioplasty (PTA) interventions and cost-effectiveness among PTA, deployment of a stent, or a stent graft in the treatment of failing arteriovenous dialysis grafts. The secondary objective was to compare the residual diameter at the site of dialysis shunt stenosis using sonography and digital subtraction angiography (DSA). Methods. Sixty patients were randomly assigned to either PTA, placement of a stent or stent graft. Follow-up angiography was scheduled at 3, 6, and 12 months or when requested by the physician. Residual diameter of a dialysis shunt stenosis was measured in 20 patients with significant stenosis by ultrasonography and on an angiogram from DSA. Results. During a median follow-up of 22.4 months patients with PTA, stent, or stent graft required 3.1±1.7, 2.5±1.7, or 1.7±2.1 (P=0.031) secondary PTA interventions. The primary patency rates were 0%, 18%, and 65% at 12 months and 0%, 18%, and 37% at 24 months in the PTA, stent, and stent graft group respectively (P<0.0001). The cost of the procedures was €7,900±€3,300 in PTA group, €8,500±€4,500 in stent group, and €7,500±€6,200 in stent graft group (P=0.45). The mean residual diameter measured by ultrasonography and DSA was...
