Issued topics of Doctoral Study Program

  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.

  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)

    Tutor: Rajmic Pavel, doc. Mgr., Ph.D.

  4. 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)

To do this, home electrical appliances will use suitable modern sensors, transmission, and reliability optimization M2M (Machine-To-Machine), and advanced communication infrastructure design. It will also be necessary to consider streamlining wireless communication protocols, taking into account wired protocols. To achieve cost savings, advanced technologies will be designed, such as mobile networks over 5G and LTE, PLC, Ethernet, NB-IoT, SigFox, and LoRaWAN.

  33. 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.

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.

  35. 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. However, they also have potential in multimedia applications including augmented and virtual reality. The problem, however, is the limitation of their dimensions with respect to the spatial filtering capability at low sampling frequencies. 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.

During the initial phase, the attention will be given to: (i) the communication technologies operating in the licensed frequency bands, i.e., those defined by 3GPP in the Release 13 and newer (Narrowband IoT, LTE Cat-M a 5G (NSA, SA)) and (ii) to the communication technologies utilizing the license-exempt frequency bands, i.e., (Sigfox, LoRaWAN). The initial findings will be used to fully understand the key principles of the Low-Power Wide-Area (LPWA) technologies. Also, to extend the knowledge, real measurement campaigns will take place using the communication prototypes built at Brno University of Technology. Finally, the obtained data will be used as the input data sets for complex simulation scenarios / analytical modeling. Next, the results will be analyzed and proposals of the new communication mechanisms targeting the optimization of the utilization of the network resources will be discussed. The attention will be focused on: (i) predictive switching between serving cells / communication technologies, (ii) optimization of the control plane traffic with the option to transmit the user data within the signaling traffic, (iii) switching between device operation states (connected, idle, power saving), (iv) forming of the MESH communication infrastructure while using the heterogeneous communication systems. Introduced principles will be then implemented within the infrastructure of the communication operator as well as on the side of the end devices. To be able to reach the above-mentioned goals, the unique laboratory at the Department of Telecommunication at BUT (UniLab) will be used. Also, while working on the dissertation thesis, cooperation with both industry and academia partners will be held.

  2. Novel distributed and quasi-distributed fiber optic sensing systems

    The work focuses on the design, simulation and development of distributed and quasi-distributed fiber optic sensing systems. These systems use conventional single-mode telecommunication optical fibers, multimode fibers, polymer optical fibers (POF), microstructural fibers, multicore fibers, or other special fibers as a sensor. Using scattering phenomena (Raman, Brillouin, or Rayleigh scattering), or possibly changing the parameters of the transmitted optical signal (change in intensity, phase, polarization, etc.), it is possible to obtain information about temperature, vibration and other physical quantities along the optical fiber.

  3. 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.
