Issued topics of Doctoral Study Program
- 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.

Tutor: Říha Kamil, doc. Ing., Ph.D.
- Artificial intelligence for person identification from low quality image sequences
When identifying offenders, the quality of the recording is often significantly affected by poor lighting conditions, low face resolution, masking part of the face or image artifacts caused by a high degree of image compression. Video recordings are often the only source of data that can be used as an evidence. The face identification is dealt with by the Criminalistics Institute in Prague, Audiovisual Department. The human eye and brain can recognize a person's face better from a sequence of images (i.e. video) than from a single still image. The objective of the research is to design methods based on artificial intelligence that will use sequence of face images and reconstruct the resulting face as a still image in better quality.
- 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)
- 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)
- 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.
- Converters for mutual A/D and D/A conversions working in the current mode
The work is focused on the design of A/D and D/A converters working in the current mode. The aim is to design a suitable structure of number-current and current-number converters without internal current-voltage and voltage-current conversions with respect to enhancing the bandwidth in comparison with converters working in the voltage mode. Part of the work is also the design and analysis of current-mode antialiasing filters. The design will start from unconventional circuit element structures such as current conveyors (CCI, CCII, CCIII) with simple or floating output, current feedback amplifiers (CFA) or transconductance amplifiers (OTA, BOTA, DBTA). Requirements to be met by the candidate: the knowledge of circuit theory and simulation programs (MicroCap, PSpice).
- 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)
- 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)
- Elastic optical networks in critical infrastructure
Fixed channel spacing distribution between separately data streams proves to be an insufficient technique. With the development of software-defined networks, there is a new trend in the reallocation of the spectrum, elastic optical network (EON). These networks react flexibly to the line occupation and predictively define spectrum allocation. With spectrum reallocation, individual interfaces may be blocked due to routing and wavelength assignment (RWA) and routing and spectrum assignment (RSA) spectrum sharing from/to access networks. Elastic optical networks can transfer the quantum key over short distances.

- Feature analysis of current-mode electronic frequency filters
The work is focused on the feature analysis of current-mode electronic frequency filters. The aim is to design algoritmizable methods that lead to finding features of filters generally defined by the schematic. It will be necessary to evaluate the available feature ranges, e.g. quality, pass-band current transfer, dynamic range within a defined supply voltage, sensitivity, etc. In the case of finding the quality range, the point is to find the extremes of a multi-variable non-linear function. Mathematical tools (e.g. Maple or MathCAD) will first be used for this purpose; afterwards the algorithm itself will be designed. Requirements to be met by the candidate: algorithm thinking, the knowledge of computer programming and circuit theory.
- 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.

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.

- Spatial Audio Signal Processing Using Small-Size Microphone Arrays
Microphone arrays of small dimensions, mainly fitted with MEMS microphones, are currently used in a number of applications, such as voice assistants, robots or monitoring in sensor networks, especially for their ability of spatial filtering of the sound signal from background noise.

The aim of this dissertation is to use new methods of spatial filtering of sound signal picked up by a field of microphones in order to further reduce the dimensions of the field and increase the resolution and accuracy of filtering. The dissertation will focus not only on the research for suitable algorithms of signal processing, but also on its mechanical design enabling the adjustment of acoustic properties of microphones, especially the shaping of directional characteristics. The research will be carried out in cooperation with the Faculty of Transportation Sciences of the Czech Technical University and the Université du Maine Le Mans.

The research will focus on problems and solutions of applied cryptography on computational and memory constrained resources. The participation on Department’s national and international research projects is expected.
- Security of Software Defined Networks
The aim is to analyse security aspects of the Software Defined Networks (SDN) technology. Optimization of existing and design of new algorithms against vulnerability of SDN will be proposed. New strategies are needed to secure the operation of the control plane, ensuring the controller is a priority. The attack vectors for SDN systems and share routes to secure the virtual network infrastructure that supports SDN and then the methods that are currently being considered in network protection play an important role. Due to the separation of the control plane from the data plane, there are several parts that must be protected from attackers. In addition to attacks on the controller, there are attacks on links, data plane devices, and applications. The application sphere of the research will be Blockchain-Based Distributed Trading in Energy Internet, smart grids, microgrids, solar energy systems and other current technologies. Selection and subsequent use of suitable simulation tools and other means is expected.
