Biography

Yiannis Andreopoulos obtained the Electrical Engineering Diploma and an MSc degree from the University of Patras, Patras, Greece. He obtained the PhD in Applied Sciences from the University of Brussels (Belgium) in May 2005. During 2002-2004, Dr. Andreopoulos made several decisive contributions to the ISO/IEC JTC1/SC29/WG11 (Moving Picture Experts Group – MPEG) committee in the early exploration on scalable video coding. During his post-doctoral work at the University of California Los Angeles (US) he performed research on cross-layer optimization of wireless media systems, video streaming, and theoretical aspects of rate-distortion-complexity modeling for multimedia stream processing systems. From Oct. 2006-Dec. 2007, he was Lecturer at the Electronic Engineering Department of Queen Mary University of London. Since Dec. 2007, he is with the Electronic and Electrical Engineering Department of UCL, currently as Reader in Data and Signal Processing Systems and academic member of the Communications and Information Systems Group

Research interests: I am working in the fields of multimedia stream processing and coding, error-tolerant computing, signal processing & transform design, and wireless protocols for low-end systems (e.g. sensor networks).

Teaching Summary


 Multimedia over IP Networks: Human factors, Image/Video/Audio formats, Coding standards, Presentation, transport, network layers, Testbeds and experiments, Industry trends, Future of multimedia, new disruptive technologies 

 This module provides a wide perspective of available communication networks and their properties. Many of the topics covered are fundamental to communication engineers regardless of whether they are working in a circuit switched or packet switched environment. 

The Syllabus covers the following topics: 
Analysis of linear systems (Laplace transform, signal flow and block diagrams), 
Feedback (Open and closed loop systems, stability analysis), 
Steady state response (System class, Nyquist plots, Bode plots, phase and gain margin, design of phase advance and phase lag compensators), 
Transient response (Root locus method, system poles and zeros, design of controllers by pole placement), 
PID control (Algorithms for industrial implementation including bumpless transfer and anti-windup), 
Non-linear systems (Linearization methods, describing function technique, limit cycle oscillations)
