Jacobian linearisation in a geometric setting
(IEEE, 2003)
Linearisation is a common technique in control applications, putting useful
analysis and design methodologies at the disposal of the control engineer.
In this paper, linearisation is studied from a differential ...
Hybrid Digital-Analog Source-Channel Coding and Information Hiding: Information-Theoretic Perspectives
(2007-10-02)
Joint source-channel coding (JSCC) has been acknowledged to have
superior performance over separate source-channel coding in terms of
coding efficiency, delay and complexity. In the first part of this
thesis, we study ...
Multitaper Methods for Time-Frequency Spectrum Estimation and Unaliasing of Harmonic Frequencies
(2009-02-05)
This thesis is concerned with various aspects of stationary and nonstationary time series analysis. In the nonstationary case, we study estimation of the Wold-Cram'er evolutionary spectrum, which is a time-dependent ...
Performance analysis of linear block codes over the queue-based channel
(2007-08-29)
Most coding schemes used in today's communication systems are designed for memoryless channels. These codes break down when they are transmitted over channels
with memory, which is in fact what real-world channels look ...
Geometric Jacobian Linearization
(2007-12-21)
For control systems that evolve on Euclidean spaces, Jacobian linearization
is a common technique in many control applications, analysis, and controller
design methodologies. However, the standard linearization method ...
Pairwise Optimization of Modulation Constellations for Non-Uniform Sources
(2009-10-07)
The design of two-dimensional signal constellations for the transmission of binary non-uniform memoryless sources over additive white Gaussian noise channels is investigated. The main application of this problem is the ...
Invariants of Modular Two-Row Groups
(2009-10-06)
It is known that the ring of invariants of any two-row group is Cohen-Macaulay.
This result inspired the conjecture that the ring of invariants of any two-row group is a complete intersection. In this thesis, we study ...
Some Advances in the Multitaper Method of Spectrum Estimation
(2009-02-09)
Four contributions to the multitaper method of applied spectrum estimation
are presented. These are a generalization of the multitaper
method of spectrum estimation to time-series possessing irregularly
spaced ...
Error-Resilient Tile Sets for DNA Self-Assembly
(2009-08-25)
Experiments have demonstrated that DNA molecules can compute like a machine to
solve mathematical problems, which is significant because of their parallel computation ability. However, due to the nature of biochemical ...
A Geometric Approach to Energy Shaping
(2009-09-02)
In this thesis is initiated a more systematic geometric exploration of energy shaping. Most of the previous results have been dealt wih particular cases and
neither the existence nor the space of solutions has been discussed ...
