1. Analog circuits containing elements with the fractional order

   The thesis is focused on modeling, simulations and experimental verification of structures where relation between response and driving signal contains derivation or integration of non-integer order (so-called fractional structures or circuits). The task is also to design of suitable application possibilities of fractional order circuits, e.g. frequency filters, reconfigurable filters, tunable oscillators or other circuits. Attention should be kept also on other ways how to implement fractional order circuits, e.g. implementation of structures with distributed parameters (RC-EDP), on computer modelling of matter and structures from nature and biology and also on mathematical description.

The need to complete the missing segment of an audio signal or to restore saturated signal samples are interesting tasks with the practical use (historical recordings, dropouts in VoIP calls, etc.). Current methods are capable of high quality interpolation of signals that are stationary in the vicinity of the missing section and have harmonic character. The study will focus on methods that combine approaches that have been successful in recent years, namely mathematical optimization methods and the deep neural networks (DNNs). Psychoacoustic viewpoint of the problem will be covered as well. (Collaboration with the Acoustics Research Institute, Vienna)

3. Compressive distributed target tracking

   The scenario considered in this PhD thesis is a network of agents that collaborate in order to track one or several moving targets in a distributed (decentralized) manner. Here, "distributed" means that there is no central unit collecting and processing all the measurements, and only agents that are spatially close are able to communicate. In many methods for distributed target tracking, statistical information is exchanged between the communicating agents, and the underlying probability distributions are sparse. The goal of this PhD thesis is to develop and study compressive and possibly other “sparsity-exploiting” methods for distributed target tracking with reduced communication requirements. (Collaboration partner: Prof. Franz Hlawatsch, TU Wien)

4. Converged networks with limited bandwidth

   Converged networks with limited bandwidth require a research of alternatives of increasing their throughput. It is about solving the problems connected with broadband data transmission, which is in its part limited by a narrower bandwidth, the so-called bottleneck problem. Come up with solution possibilities and subsequently design, model and implement a new system on the NetCOPE platform. Consider solutions based on QoS, solutions based on compression algorithms, and their combinations. Knowledge in the area of IP networks, modelling in Matlab and Simulink, and programming in languages VHDL or Verilog are supposed. You are supposed to compare your system with existing ones and to specify its advantages.

5. Data Fusion in Decentralized Sensor Networks

   Bayesian multi-sensor data fusion is concerned with the combination of statistical information from several sensors to improve statistical inference. An example is the fusion of multiple sensing modalities (such as LIDAR and cameras) in autonomous vehicles. In this thesis, the focus is on distributed fusion methods, where no central entity performing the data fusion exists and sensors can only communicate with other sensors that are within a certain distance. Although several approaches to distributed sensor fusion have been proposed, no unified framework exists that addresses issues such as rumor propagation (double counting of information), spurious data, and out-of-sequence data in dense sensor networks. The goal of this PhD thesis is to develop and study efficient and robust sensor fusion methods that address these issues. (Collaboration partner: Prof. Franz Hlawatsch, TU Wien)

6. Dictionary Learning for Representing Probability Distributions

   The sparse approximate representation of probability distributions is important in many applications of statistical signal processing and machine learning. One important application scenario is distributed detection or estimation in decentralized sensor networks, where probability distributions have to be communicated between physically remote units (e.g., vehicles or robots). This PhD thesis project focuses on the expansion of a probability density function into a dictionary of functions that is chosen in an adaptive manner (“dictionary learning”). The goal of the thesis is to develop and study optimal and/or suboptimal methods for dictionary learning that address a joint criterion of sparsity and accuracy. Of further interest is an extension of these methods to a sequential mode, which is needed for tracking applications. (Collaboration partner: Prof. Franz Hlawatsch, TU Wien)

9. Feature extraction of non-integer order systems

   The topic deals with the proposal and verification of electrical measurement methods suitable for direct and indirect parameter determination of non-integer (also referred to as fractional) order systems. This could be achieved e.g. by suitable input signal being applied to the function block containing the analyzed sample/tissue and further analysis of the time and/or frequency response. The electrical parameters and their relationship determined in this way define specific other physical or chemical properties of the analyzed systems. The proposed methods enable fast and efficient measurement of real properties of the analyzed systems and supplement the direct physical or chemical properties’ measurements methods, which however may be time consuming or even more expensive.

19. Optical fiber amplifiers

    The ongoing growth of telecommunications networks is currently made possible by optical fibers. Together with telecommunications systems, optical amplifiers have made it possible to transmit huge amounts of data from kilometers distances to transoceanic distances, providing the capacity needed for current and future communications networks. Optical amplifiers play an important role not only in optical telecommunications, but also in optical sensing and many other applications. Rare-doped amplifiers (eg Erbium-doped fiber amplifiers), Raman amplifiers, and semiconductor optical amplifiers (SOA) are common today. Special types of amplifiers such as parametric amplifiers offer many advantages, but they are complex and expensive. In addition to the amplifiers themselves, new types of optical fibers (eg multicore) and the possibilities of amplification in these fibers have to be considered.
