Nonlinear Modeling and Parameter Estimation of Syncronous Machines Using Online Measurements
Investigator Name: Elias Kyriakides (UCY)
Co-Investigator Names: Demetrios Papadopoulos (Democritos University of Thrace, Greece), Gerald T. Heydt (Arizona State University, U.S.A.)
Period: 1/7/2007-30/6/2009
Amount: 34,200 euro
Funding Agency: University of Cyprus, Research Fund
Description: Accurate modeling of synchronous generators is a key component in obtaining reliable results from transient stability studies and other routine power engineering studies. The available off-line techniques are often not practical and do not capture the behavior of the generator at all operating
levels. Generator parameters are in general not constant throughout the useful life of a synchronous generator. Generator parameters vary because of aging, changes of the generator internal temperature, magnetic saturation, and coupling between the generator and external systems. Parameter estimation is necessary to ensure that the parameters used in different power system studies are accurate, and to enhance the confidence in the interpretation of the results of such studies. The aim of this project is to estimate the model parameters of synchronous generators by using actual voltage and current measurements obtained at the machine terminals while the generator is connected to the power grid. Further, the generator parameters are estimated at different operating levels of the machine, and therefore a detailed machine model needs to be developed in order to capture the generators’ response due to saturation and other operating point dependencies.
Intelligent Computer Control of Water Systems in Cyprus
Principal Investigator Name: Marios Polycarpou (UCY)
Co-Investigator Name: Andreas Manoli (Water Development Department, Cyprus)
Period: 1/8/2004-31/7/2006
Amount: 52,500 euro
Funding Agency: University of Cyprus, Research Fund
Description: This project aims to develop and simulate methods for automatic feedback control of both quantity and quality dynamics in water distribution networks. The hydraulic control objective is considered in terms of water pressures at point of consumption, while the quality control objective focuses on the regulation of chlorine residual at points of consumption. The proposed approach is based on approximating the input/output dynamic behavior and transport delay of chlorine concentration between an injection node (input) and a monitored node (output) as a time-varying, discrete-time linear model with unknown coefficients, which are estimated on-line and used for feedback control.
Convergence of Communication, Control, and Statistical Mechanics with Applications to Network Sensors and Tele-Operation
Principal Investigator Name: Charalambos D. Charalambous (UCY)
Co-Investigator Names: Andreas Kyprianou (UCY), Stavros Kassinos (UCY), Nasir Ahmed (University of Ottawa, Canada), Alireza Farhadi (University of Ottawa, Canada), Farrokh J. Sharifi (Ryerson Polytechnic University, Canada), Seddik Djouadi (University of Tennessee, USA)
Period: 1/7/2004-31/6/2007
Amount: 131,250 euro
Funding Agency: University of Cyprus, Research Fund
Description: This project consists of a theoretical part and an experimental part. The theoretical part deals with large scale complex systems, in which the traditional areas of Communication, Control, and Statistical Mechanics are converging, while being subject to uncertainty, capacity and power constraints. The experimental part is concerned with the application of the theoretical work in sensor networks, control over wireless links, and tele-operation systems, in which the theoretical results and algorithms are tested and evaluated.
Development of Advanced Karyotyping Technology
Principal Investigator Name: Constantinos Pitris (UCY)
Co-Investigator Name: Phillipos Patsallis (Cyprus Institute of Neurology and Genetics, Cyprus)
Period: 1/12/2003-1/4/2004
Amount: 31,500 euro
Funding Agency: University of Cyprus, Applied Research Fund
Description: Human chromosome analysis is an essential task in cytogenetics, especially in prenatal screening, genetic syndrome diagnosis, cancer pathology research and mutagen dosimetry. Both manual and automatic classification of chromosomes are limited by the resolution of the microscope and imaging system used. One way to improve the results of classification and even detect subtleties now remaining undetected, is to enhance the resolution and quality of the chromosome images. It is possible to achieve lateral resolution, well beyond the classical limit, by using spatially modulated illumination (SMI) in a wide-field, non-confocal microscope. In this method, the sample is illuminated with spatially modulated light, which makes normally inaccessible high-resolution information visible in the observed image by shifting higher frequencies within the OTF limits of the microscope.

Development and Deployment of Location Based Services in Wireless Networks
Principal Investigator Names: Charalambos D. Charalambous (UCY), Christos Panayiotou (UCY)
Co-Investigator Name: Marios Polycarpou (UCY)
Period: 1/9/2003 – 31/12/2003
Amount: 38,500 euro
Funding Agency: University of Cyprus, Applied Research Fund
Description: Access of the right information “anytime, anywhere” is becoming the new driving force that drives the information technology revolution. The “right” information is information that is relevant based on the user’s profile and his/her current position and/or time. Such services will contribute in improving individual and public safety (e.g., report the position of a casualty or of a fire). They will also facilitate effective information dissemination and enable individual or asset tracking. The benefits of such services will be immediately obvious to a number of industries as well as visible to many individuals. This project aims at developing the technologies that will allow wide deployment of location based services. Specifically, during this project we investigated various Automatic Location Identification (ALI) techniques (ALI techniques utilize the received signals at a mobile terminal to estimate the location of the user).
