This thesis deals with creating a software guitar looper in a visual programming language called Pure Data and also building a specific remote controller for it. The remote cont- roller will be based on a MIDI protocol. As a part of the software, there will be a special aligning algorithm, that will take care of precise alignment of the created loop on beat in the way that no other intrusive rhythmical or tempo related elements are present.

This thesis focuses on problematics of DAW controllers for sound production software. In this thesis is analysed Mackie Control protocol, one of used communication protocols. There is also an overview of MIDI messages, because Mackie Control protocol is based on MIDI protocol. The thesis contains two own DAW controller designs. First one is based on Mackie Control protocol, second one is based on Generic Remote which offers better customization.

This diploma thesis deals with familiarization with available frameworks in the PHP language working in a thin client environment. It focuses on the comparison of two frameworks CodeIgniter and Zend Framework. The next section provides a detailed description of framework libraries. I suggested sample application made by two frameworks for a comparison, which contains the basic elements, that are used in creating majority of web applications. In the conclusion there are compared pros and cons of development environments.

<p>У дисертацији је дат концепт микро мрежа и описане постојеће методе у управљању и оптимизацији рада микро мрежа. Предложен је нови централизовани контролер микро мрежe заснован на технологији више-агентног система, који омогућава координацију три режима рада (повезани, острвски и хаваријски) и обезбеђује једноставну конфигурацију и комбинацију оптимизационих критеријума, уз уважавање широког скупа ограничења. Предложени модел примењен је на релевантни тест систем и резултати су приказани уз одговарајућу анализу резултата.</p> / <p>U disertaciji je dat koncept mikro mreža i opisane postojeće metode u upravljanju i optimizaciji rada mikro mreža.

This paper proposes a novel, centralized, multi-agent-based, microgrid controller architecture, which provides the coordination of all three operation modes (grid-connected, island and emergency) and enables the easy configuration/combination of optimization goals that are subject to a given set of operational constraints.<br />The simulation results are presented for a typical microgrid test example.</p>
