Issued topics of Doctoral Study Program
- Box Particle Techniques
The particle filter is a computationally feasible technique for sequential Bayesian estimation in arbitrary nonlinear/non-Gaussian scenarios. The box particle filter is a recent variant of the particle filter with significantly reduced complexity. The goal of this thesis is to develop a distributed version of the box particle filter, and to investigate the application of box particle techniques to belief propagation message passing and/or to Bayesian filters based on random finite sets, such as the PHD filter or the multi-Bernoulli filter.

- Cloud services in Internet
Cloud services are a modern technology that, for example, allows data storage on the Internet without restriction to a specific server. With distributed systems, a number issues are to be solved, such as the server distribution for the data storage, backuping and restoring the data, users' privacy assurance, scalability, and data availability.
- Completing missing samples in audio using modern techniques
The need to complete the missing segment of an audio signal is an interesting task with the practical use (restoration of 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 would focus on improving these methods by advanced signal processing approaches. Psyhcoacoustic viewpoint of the problem should be covered as well. Cooperation with the academy of Sciences Vienna.
- Controlled Sensing for Distributed Localization in Agent Networks
In location-aware scenarios, agents determine their own positions (self-localization) and possibly the positions of other objects (target tracking). In active localization methods, the transmitted waveform has a strong effect on the localization performance, especially in the presence of multipath. The goal of this thesis is to adapt the transmitted waveform using an “information-seeking” control scheme, such that the relevant information carried by the measurements of all the agents is maximized.

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).

The design and optimization of new protection techniques for these systems is expected on the basis of obtained observation. Optimization involves the proposals of both mechanisms to improve the distributed systems and the procedures to either minimize or prevent the negatives effects affecting the functions of such is expected to propose the mathematical tools to describe the novel mechanisms. It is supposed to simulate or experimentally verify the functionality of the proposed solutions.

- Environmental Noise Monitoring and Assessment
Environmental noise is a worldwide problem that persists even in areas where extensive resources have been used for regulating, assessing and damping noise sources or for creation of noise barriers. Environmental noise protection requires making measurements in the field, assessing noise from specific sources, calculating expected noise levels, and mapping noise levels. The aim of this doctoral thesis is research of a new concept of permanent monitoring and assessment of environmental noise with identification of the noise sources and interactive mapping that uses modern wireless sensor networks with real-time monitoring and data visualization. The thesis topics comprise research and implementation of the noise analysis algorithms and design of a noise sensor hardware as well.
- 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.

Cybersecurity is important for the privacy assurance of the Internet users, while attackers try to gather as much information as possible and use it against them. One of the possible solutions is to prevent cyber attacks by monitoring the network communication and analysing the data captured.
- Internet for emergency services
Nowadays, the use of the public Internet is limited for communication with emergency services, such us police and emergency medical service. The reason is that the current networking technologies for emergency communication including voice/video/text transmission do not have the properties and parameters required. An example is detection of the geographical location of a caller in emergency.
- Internet of Things
Internet of Things (IoT) is a new trend covering interconnection of the different types of devices using the Internet. For such devices, new ways of network communication are needed. The basic applications of IoT are environmental monitoring, medical systems, smart homes, and transportation of people and goods.
- Interoperability and secure data sharing between the components of Internet of Things ecosystem
In order to fully realize the vision of the Internet of Things (IoT), devices and apps need a common way to interact and speak to each other. Therefore, it is really important to create universal platform which will act as an interconnecting element for different vendor-, programming language- and communication technology-independent components of IoT ecosystem. The main goal of the doctoral thesis is to propose and develop the multi-platform middleware which will be implemented on an intelligent IoT gateway to provide common services and interfaces for secure communication, data sharing and control functions for IoT applications, sensor and actuators. One of the key tasks is to propose an open smart object data model and universal syntax to enable the information sharing between devices and sensors.

- Object-Based Audio Processing
In an object-based audio system, the different sound elements are bundled with metadata to form audio objects. This metadata then describes how the sound element should be reproduced to the listener, by defining its position in the 3D field, regardless the sound reinforcement system. Currently there are a number of approaches for positioning the audio objects, particularly ambisonics, VBAP, DirAC, and wavefield synthesis. Each of them has its advantages and disadvantages. The aim of this doctoral thesis is to analyze the possibilities of using these methods in real installations and to design and test new algorithms for positioning audio objects in 3D space.
