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.

In this thesis, an agent network performing distributed tracking of one or several targets using an active localization method is considered. The transmitted waveform is reflected by scatterers such as walls of buildings or rooms, leading to multipath propagation. The goal of this thesis is to develop a distributed target tracking method with implicit estimation of the multipath parameters, possibly using knowledge of a map (floor plan) of the environment. This work will be based on an existing distributed tracking method using belief propagation message passing and a consensus scheme. (Collaboration partner: Prof. Franz Hlawatsch, TU Wien)
The scenario considered in this thesis is a network of agents that collaborate in order to track a moving target in a decentralized manner. Here, "decentralized" 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 such a decentralized tracking scenario, exchanging statistical information between the agents can be simplified considerably if the statistical distributions are sparse. The goal of this thesis is to develop and study the application of compressed sensing methods to the task of exchanging sparse statistical distributions.

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.

Mathematical description, modeling, implementation and practical use of these circuits are also included.

The fundamental frequency is the one of the important parameters of the speech signal. Its estimation is due to the nonstationary of speech signal quite difficult. Empirical mode decomposition is an advanced method for analyzing nonstationary signals based on signal decomposition into intrinsic mode functions adapted to the base signal content. The instantaneous frequency, among other parameters, can be determine using the Hilbert transform. The content of the dissertation research will be research of the basic method of detection frequency tone and its comparison with other known methods.
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-EDPs. 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.
