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

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
