1. Quantized Feedback for Slow Fading Channels
Abstract : Two topics in fading channels with a strict delay constraint and a resolution-constrained feedback link are treated in this thesis. First, a multi-layer variable-rate single-antenna communication system with quantized feedback, where the expected rate is chosen as the performance measure, is studied under both short-term and long-term power constraints.

2. Hybrid observers for systems with intrinsic pulse-modulated feedback
Abstract : Dynamical processes resulting from the interaction of continuous and discrete dynamics are often encountered in living organisms. Time evolutions of such processes constitute continuous variables that are subject to instant changes at discrete points of time. READ MORE

3. Input-Output Stability Analysis of Networked Control Systems
Abstract : The main focus of the thesis is to derive stability criteria for networked control system (NCS) models featuring imperfections such as time-varying and constant delays, quantization, packet dropouts, and non-uniform sampling intervals. The main method of proof is based on matrix algebra, as opposed to methods using Lyapunov functions or integral quadratic constraints (IQC). READ MORE

4. Distributed Control of Electric Drive Systems via Ethernet
Abstract : This thesis is on adapting standard Switched Ethernet for distributed control applications in electric drive systems. The critical issue of Ethernet here is to provide services to real-time applications. READ MORE

5. Dialogue processes in computer-mediated communication : a study of letters in the COM system
Abstract : This thesis concerns the basic communicative potentials of a new communications medium: computer-based communication systems. The computer medium has properties which makes it possible to carry out an interactive dialogue, although messages are written and there is a delay between successive contributions. READ MORE
