Abstract: The continuous increase on the penetration levels of Renewable Energy Sources (RES) in power systems has led to radical changes on the design, operation and control of the electrical network. Since the issue of the Directive 2009/28/EC of the European Parliament, each country-member of the European Union, has set specific targets to achieve in accordance to the Directive. Consequently, with renewable energy sources’ integration increasing at a fast rate, the shape of the grid is continuously changing, thus revealing the dynamic nature of the subject. This work investigates the influence of these changes on the operation of a transmission network by developing a set of indices, spanning from power losses to G.H.G emissions reduction. These indices are attempting to quantify any impacts therefore providing a tool for assessing the RES penetration in transmission networks, mainly for isolated systems. These individual indices are assigned an analogous weight and are mingled to provide a single multi-objective index that performs a final evaluation. These indices are used to evaluate the impact of the integration of RES into the classic WSCC 3-machine, 9-bus transmission network.

Real-Time Hand Tracking for Human-Computer Interaction

Title: Real-Time Hand Tracking for Human-Computer Interaction

Dr. Paris Kaimakis

Wednesday, 26th September 2012, 17:30 – 18:30
Room KENTP. ΠΤΕΡ. – E113, Old Campus, University of Cyprus

Abstract: The successful commercialisation of Microsoft’s Kinect has recently demonstrated the increasing demand for reliable, low-cost, real-time Markerless Motion Capture systems — systems that can sequentially estimate the subject’s 3D pose based on visual information, without markers. Such systems have numerous lucrative applications, e.g. in human-computer interaction, computer gaming, animation, automated surveillance, and more.
The last decade has seen minimal progress in the field, mainly due to the conflicting design criteria of such systems: real-time processing indicates that implementation of gradient-based algorithms is necessary for tracking, while the low-cost criterion disqualifies the use of dedicated hardware and therefore imposes use of low-level and often ambiguous data. The problem is that gradient-based approaches become very unstable in the presence of such ambiguity.
In this talk we introduce a system designed to circumvent these difficulties, achieving real-time tracking of the human hand with high precision and zero hardware requirements further to an ordinary laptop. The talk will focus on the system’s early design and modelling steps, as well as its Bayesian formulation.

Biography: Dr Paris Kaimakis conducted his doctoral research in the Signal Processing Laboratory at the University of Cambridge focusing on solutions to the Markerless Motion Capture problem. After receiving the PhD degree in 2009, he worked as a Research Associate in the Computer Laboratory, again in the University of Cambridge. His post-doctoral research concentrated on the automation of urban road traffic surveillance and flow-volume estimation using visual means and sequential Monte Carlo methods. In 2010 he joined Autonomy, the UK’s largest software firm, as a Research and Development Engineer. While in Autonomy, he worked in the development of augmented reality applications for the iPhone/iPad and for Android devices. He has been involved in the development of the popular Aurasma App, the world’s first visual browser (over 3 million users, available at the App Store and Google Play) and worked in related side-projects such as 3D head tracking, image processing and image analysis. In 2011 Paris returned to Cyprus and co-founded a company dedicated to the development and commercialisation of new-generation, human-oriented, controller-free computer interfaces.

Title: Applying the Network-on-Chip principles to systems overlaid on the FPGA fabric

Dr. Georgios Dimitrakopoulos
Electrical and Computer Engineering
Democritus University of Thrace
Xanthi, Greece

Thursday, 13th September 2012, 17:30 – 18:30
Room XOD 02 – 114, New Campus, University of Cyprus

Abstract: The rapidly-growing capacity of Field Programmable Gate Arrays (FPGAs), combined with the steady introduction of hardwired support for a multitude of diverse interfaces and functionalities, has promoted FPGAs to an attractive and capable platform for hosting even extended System-on-Chip (SoC) designs. The integration of the ovelaid (on-FPGA or soft) platform and the communication of its components requires also an efficient overlaid communication mechanism. Scalable interconnection networks that use a network of switches connected with point-to-point links can parallelize the communication between soft modules and improve performance significantly. Such on-chip interconnection networks are already a mainstream technology for ASICs, while they are becoming a need and critical in FPGA-based systems. ASIC-oriented interconnection networks even if appropriately customized for the on-chip environment, still lead to sub-optimal designs when transferred directly to FPGAs. This deficit is attributed to the inefficient mapping of the network’s switches and their components to the configurable logic array of the FPGA, which is a peculiar hardware realization substrate in terms of the relative speed and cost of logic vs. wires vs. memory. This talks presents the implementation constraints set by the FPGA fabric for the design of soft interconnection networks and presents new FPGA-targeted architectures. The described techniques focus on the fined-grained decomposition of the switch and the adoption of an elastic flow control mechanism.

Biography: Georgios Dimitrakopoulos received the Diploma in Computer Engineering from the Computer Engineering and Informatics Dept. of the University of Patras in 2001. In 2003 he completed the M.Sc. in “Integrated Hardware- Software Systems” and in 2007 he earned the PhD from the same department.

Seminar: Grid-Connected Small Wind Electric Systems and the Bidirectional Impact between distributed RES and Small Island Grids

by Jake T.

Andreas Armenakis

Venue: Unesco Amphitheatre, University of Nicosia

Wednesday, June 20, 2012, 6-7 pm

Abstract:  

The ambitious European 20-20-20 targets will increase the penetration of Renewable Energy Sources (RES) in the grid, including small and efficient units distributed in the medium or low voltage networks. As Distributed Generation (DG) spread in a geographic area, time, location and weather inter-dependencies, loads and demands get more importance, introducing breakthrough changes in the way electricity will be generated, distributed and used. Due to the increase in the numbers of RES connected to the Distribution Network, and the requirement of the European Distribution System Operators (EDSO) to integrate them sufficiently into the network, grid code compliance rules have been implemented to ensure system contribution of RES without disturbing the quality, safety, and reliability of the grid. Before connection to the grid, RES must verify that they comply with regulations, such as voltage control – both steady state and dynamic, voltage dependent reactive power injection or absorption, and fault ride through stability.

Biography:

Andreas Armenakis graduated in Electrical Engineering (Leipzig) followed by a Master in Engineering (Berlin). He worked for 10 years in Germany for Siemens and Preussag (today Babcock) and also in Cyprus for the Carlsberg Brewery, designing and executing complex Energy and Automation projects. Today, Andreas works for the Electricity Authority of Cyprus, developing the High Voltage Distribution Network, including the integration of Renewable Energy Sources (RES). His publications are mostly related to Energy Management and Integration of RES.
