1. Optimal control of gain and offset in direct conversion receivers : magistrsko deloAmadej Maurič, 2023, magistrsko delo Opis: In the master’s thesis, the development and implementation of optimal control for direct conversion receiver is presented. A background overview of direct conversion receivers, in-phase and quadrature mixers, sampling theory, control theories, adaptive systems, and optimal control is given. The development of a system model which is later used in simulations is also presented.
Optimal control is achieved through standard control techniques, such as feedback and feedforward control, with error functions giving restrictions. Information to feed the optimal control is acquired by the system through the analog converters to the digital converters, digital to analog converters, and received signal strength indicators.
For the development and testing of optimal control, MATLAB environment was used. Simulations and presentation of the results were also done in MATLAB. Limitations, exact operation, and comments were given throughout the thesis

2. MUSIC STUDIO - ARCHITECTURAL ALTERATIONS FOR CONVERSION AND REUSE OF AN OLD BARN IN BODENSDORT, CARINTHIATadej Kočevar, 2015, magistrsko delo Opis: Due to the increasing loss of local architecture and the identity of the
rural environment, preservation of our cultural heritage should be one
of the key points of rural development. This thesis deals with the
renovation of the barn in the music studio.
The thesis explains the characteristics of vernacular architecture,
discusses the attitude towards renovations of older buildings and
summarizes the basic acoustical design principles. Based on the
theoretical knowledge, the second part includes the renovation project
of a barn into the music studio, which respects its local ethnological
and architectural heritage, and represents a sustainable solution.
It was established, that renovations of older local architecture have to
be encouraged.

4. In-line higher order mode filters based on long highly uniform fiber tapersDenis Đonlagić, 2006, izvirni znanstveni članek Opis: This paper presents a simple and effective design of taper-based higher order mode (HOM) filters that can effectively remove HOMs from the few-mode fibers. For this purpose, a taper manufacturing technique that allows the production of long and highly uniform tapers was developed. A filter performance was demonstrated on a standard single-mode telecommunication fiber operating at 850 nm. The HOM suppression was better than$-$39 dB, and the insertion loss ofthe fundamental mode was less than 0.15 dB.
