- 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.

Neural networks and machine learning are currently used in the area of audio signal processing for data mining, eg. recognition of genre, music information retrieval from recordings, etc., and speech processing, such as word recognition, speaker identification, emotion recognition, etc. However, their potential use is also in modelling analog musical effects, audio and acoustic systems etc. This topic focuses on the area of audio system modelling, with the emphasis on minimizing the need for manual labeling of recordings for training of neural networks.
- Using Machine Learning to Control Parameters of Audio Signal Processing
Neural networks and machine learning are currently used in the area of audio signal processing for data mining, eg. recognition of genre, music information retrieval from recordings, etc., and speech processing, such as word recognition, speaker identification, emotion recognition, etc. However, their potential use is also in other areas of audio signal analysis and processing. This topic focuses on the controlling parameters of audio signal processing systems using machine learning and on utilization of hearing models for training of neural networks.
- Virtualization of network functions and services
Trend of modern data networks is characterized by transition from specialize hardware based network components towards components based on powerful unified hardware that can be customized by software and its configuration to particular network function. Thanks to virtualization platforms it is possible to introduce it in distributed form. The goal of PhD thesis is to make research of potential of network function virtualization, and design of new network applications.

- Advanced Classification of Textural Features
The thesis is focused on definition and analysis of textural features in images of sedimentary grains acquired by electron microscope device. The main goal of the work is to objectivize and to automatize the estimation of exoscopic parameters of given grains with the purpose to statistically classify the grains into different classes based on a geomorphological processes which contributed to form a given analysed grain structure.

- Automated design of neural network architecture using genetic programming
Artificial neural networks are currently one of the most successful form of artificial intelligence deployed to images, videos, or text analysis. The current trend of neural network design lies not in increasing complexity of the networks but rather in effective design of neural network architecture. This architecture has to be designed for each problem in parallel. The objective of the dissertation is to automate the search for optimal neural network architecture using graph theory and genetic programming. The comparison should be designed with respect to current modern architecture of massive parallel hardware and computational complexity of individual algorithms.
- Fibre-optic sensors
The work focuses on a design, simulation and realization of fibre-optic sensors. These systems use conventional single-mode telecommunication fiber, multimode fibre, plastic POF (Plastic Optical Fibre), microstructure fibre, or other special types of fibres as a sensor or fibre serves as a transmission medium from sensors. By using of scattering phenomena (Raman scattering, Brillouin scattering, Rayleigh scattering), eventually by change of some parameters of an optical signal (changes in intensity, phase, polarization, spectrum, etc.) it is possible to obtain information about many physical quantities along the optical fibre.
- Modelinng of varying acoustic enviroment
The goals of PhD. study are concepts, algorithms, and systems for modeling sound propagation in variyng environment. The work will be focused on modeling the propagation of early reflections and perceptually-based statistical techniques that provide late reflections and subsequent reverberation with the moving sound source and/or listener.

- Multicarrier modulations in optical transmission systems
Multitone modulations are today frequently used modulation techniques, e.g. in ADSL, VDSL, PLC, DVB-T, DVB-T2, WLAN IEEE 802.11a, g, n technologies. In all the above mentioned systems the known and well described modulation DMT (Discrete MultiTone) or OFDM (Orthogonal Frequency Division Multiplexing) is used. The work will be focused on possibilities of utilization of multicarrier modulations in optical transmission systems.

- Reconstruction of three dimensional non-Cartesian ultrashort echo-time (UTE) MR data using compressed sensing
The non-Cartesian acquisition methods attract attention because of a variety of unique properties which can be exploited for different applications such as: acquisition acceleration, insensitivity to motion and the possibility to image tissues with very short T2s (e.g. cortical bones, tendons, ligaments, menisci and myelin). The objectives of the PhD study are to: a) develop an efficient volume reconstruction method from UTE data for quantitative analyses of ultrashort T2 components, based on nonconvex optimization, b) explore the limits of the spatial resolution when reducing the number of UTE projections for acceleration, c) apply and perform quantitative in vivo MR data analyses. Collaboration with CEITEC MU center, processing of data from the experimental MR scanner, supervisor specialist Ing. Peter Latta, CSc. Potential financial support from CEITEC.
- Research of new methods of using an elliptic curves in cryptosystems
The work focuses on research of new methods of using an elliptic curves in cryptosystems based on the new findings in the field. The research focuses on effective methods for generation of new elliptic curves as well as on the analysis of elliptic curve attributes and its behavior on different hardware platforms. That means to create an effective generator of cryptographic elliptic curves. Based on obtained knowledge from in-depth analysis and experimental measurements, the research will continue with a focus on the application of one-time pad algorithms such as Vernam cipher. Last but not least, the work will result in new own cryptographic protocol based on so-called one-time elliptic curves.
- Security of 5th Generation Networks in V2X Communication System Environment
The doctoral study will cope with the security of communication in cooperative intelligent transport systems; between the vehicle and all other components of this system (V2X). After analysing security options and possible attacks on 5th Generation Networks in V2X communication systems, vehicle-vehicle, vehicle-infrastructure, and vehicle-pedestrian scenarios the methods for attack testing equipment will be developed and the methods improving communication security will be designed.
