- 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.
- Analysis and emulation of fractional systems
The description and realization of fractional systems gain on attention in numerous engineering areas, e.g. as a tool for in vivo non-invasive measurement and subsequent analysis. The aim of the thesis is the description and design of methods and tools suitable for analysis of real systems using fractional calculus and their modelling.
- Audio restoration methods based on combination of optimization and neural networks
The doctoral study will cope with modern methods of audio restoration. 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)
- Bayesian 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)
- Communication strategy for Smart Grids and IoT
The aim of the work is to design the optimal strategy for Smart Grids communication infrastructure based on analysis of suitable communication technology and in the process of deployment of IoT in Smart Cities and smart meters rollouts in Smart Grids.

- 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)

- Research of speech parameterization methods used for differential analysis of hypokinetic dysarthria and apraxia of speech
Hypokinetic dysarthria (HD) is a motor speech disorder caused by lesions in basal ganglia, usually in the case of Parkinson’s disease. In contrary to HD, apraxia of speech (AOS) is disorder of verbal communication planning or programming, and is caused by lesions in premotor cortex. Although HD and AOS are different speech disorders, they have common symptoms, and they are both manifested in fields of phonation, articulation, prosody and respiration. Therefore, the differential analysis is quite challenging. The aim of this PhD thesis is to research speech parameterization methods that will enable detailed quantification of large range of specific speech disorders and support differential analysis of HD and AOS. The research will be held in cooperation with neurologists and speech therapists from University of Arizona, University of Szeged, St. Anne's University Hospital in Brno and Central European Institute of Technology.

Based on gained knowledge during the doctorate study, the student will analyse, simulate and implement selected scenarios of attacks. The study goal may be a theoretical and practical security proposal in relation to the operating system functionality and its use.
- Sequential Estimation of Arterial Wall Contours
Examination of the common carotid artery (CCA) based on ultrasound measurements is an effective method for detecting cardiovascular diseases. In particular, the spatial evolution of the CCA wall is related to diagnostically relevant parameters describing, e.g., CCA tissue elasticity. Accordingly, the goal of this PhD thesis is to estimate the time-varying contour of the CCA wall from an ultrasound video sequence. This is to be achieved by developing a sequential extension of a machine learning method known as Gaussian process regression (GPR). In the GPR method, a function to be learned is represented by a random process, which avoids an explicit parametric representation. The desired sequential extension of the GPR method should be able to continuously track the detailed shape of the CCA wall over a time period of arbitrary duration.

- Smoothing Methods for Arterial Wall Motion Tracking
Examination of the common carotid artery (CCA) from ultrasound measurements is an effective method for detecting cardiovascular diseases. The goal of this PhD thesis is the development of time-recursive methods for tracking CCA- related multiple scatterers in an ultrasound videosequence. These methods will be based on hidden Markov models describing the temporal evolution of the scatterers and smoothing techniques for multitarget tracking, and they will take advantage of the strong statistical dependencies of the scatterers. The smoothing approach is expected to outperform current filtering approaches at the expense of a higher computational complexity.
