Issued topics of Doctoral Study Program
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 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.

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.

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.

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.

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.
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 (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.
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.

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.
Nowadays, the classic operating systems are ported on dedicated devices that usually have restricted resources or one system function is preferred to the others. One of the commonly used systems for this purpose is OS Linux. A number of Linux optimization project exits, such as to minimize the operating system size or to increase performance for specific real-time applications.

The topic aims at the research into utilization of resistive-capacitive elements with distributed parameters (RC-EDP) in electrical circuits especially with modern active elements (conveyors, current amplifiers etc.). In particular it will include design of so-called fractal circuits which have non-integer order of transfer or immittance function and which can be implemented by RC-EDP. It is expected proposing new frequency filters, oscillators, synthetic immittance elements and other circuits. The aim will be improving properties compared to existing circuits (reducing dimensions, increasing response speed, decreasing power consumption etc.) and moreover obtaining characteristics that cannot be realized by classical elements or only at the cost of using complex structures.
