Multi-threading Computer Architectures

by Jake T.

Multithreading is a programming and execution model, that allows multiple threads to co-exist on the context of the same processor and aims to exploit the large number of resources available on the chip both to improve performance and reduce energy consumption.

This survey is dealing with multithreading in general, what it is, the computer architectures that support it and other methods that can be applied to produce it using software or hardware based synchronization units. Along with the various technologies used to execute multi-threaded applications, we will cover also some implementations of multi-threading technologies. We will analyze the general types of multithreading which can be categorized in the following execution types: Explicit:Blocked, Non-Blocking, Interleaved, Simultaneous and Implicit. We will also present the basic differences between each type and we will show both hardware and software implementations that we found in the papers we read.

Efficient Modeling and Simulation of Mechatronic Systems by Example of Wind Turbines

Department of Electrical and Computer Engineering

Title: Efficient Modeling and Simulation of Mechatronic Systems by Example of Wind Turbines

Dr. -Ing. habil. Andreas Müller,
Institute of Mechatronics,
Chemnitz, Germany

Wednesday, 28th November 2012, 17:00 – 18:30
ΚΕΝΤΡ. ΠΤΕΡ. – Ε113, Old Campus, University of Cyprus

Abstract: Control of advanced mechatronic systems requires adequate models reflecting the dynamics and the interaction of electrical, magnetic, and mechanical subsystems. For such strongly coupled systems the proper representation of domain interactions is crucial. This is achieved by a holistic approach modeling mechatronic systems by energetic state functions. Their dynamics is then governed by the Lagrangian motion equations in a unified manner. In this presentation the Lagrange model for electro-magneto-mechanical systems (EMMS), consisting of energetic state functions and a dissipation function, is briefly recalled. It automatically takes into account the nonlinear domain interactions, and is complemented by additional models for hysteresis in ferroelectric and ferromagnetic elements.
A contemporary example of controlled mechatronic systems are wind turbines. Wind turbines have become the sustainable backbone of green energy. This is not at least triggered by the availability of high-fidelity models enabling realistic numerical simulation of the turbine dynamics. Such simulation models, combining non-linear flexible and rigid substructures, wind field as well as converter and operational management, allow for detailed investigations of all parts of the turbine and its overall performance. However, such investigations require too long simulation times.
For a wind turbine design to get certified it must pass extensive simulation runs. The current standards require a few thousand different load case scenarios, which apparently poses a great challenge to the simulation tools. Even more, automatic mass simulation of predefined load cases requires capabilities that standard simulation tools are lacking, including parallel computation features that are indispensable for such applications.
In this talk an approach toward tailored software solutions for distributed batch simulation of wind turbines is discussed. The turbine model is described in detail and implementation issues are addressed. Special emphasis is given to the structure of the software. The reported simulation tool is validated and successfully applied in the industrial design and certification.
The talk is intended for anyone who is interested in dynamics simulation of mechatronic systems and in wind turbines in particular. The lecture can also be taken as crash course to the current state of technology in the wind turbine sector.

Chaotic electronics and applications

Department of Electrical and Computer Engineering

Title: Chaotic electronics and applications

Dr. Stavros G. Stavrinides
Visiting Assistant Professor,
Department of Electrical and Computer Engineering
University of Cyprus

Abstract: Chaos is a universal phenomenon, exhibited by complex systems. Although it seems to be random, it is not stochastic, but deterministic. Since almost all processes in nature are nonlinear, complex (chaotic) phenomena are the norm. Thus, one can realize the significance of applied chaos theory in all fields of science, engineering, economy and social sciences. Since nonlinear circuit behavior has attracted the interest of the scientific and engineering community, during the last decades, numerous circuits have been presented. Next to that, experimental study and verification of chaotic phenomena, utilizing nonlinear circuits, have been portrayed. Moreover, applications of chaotic operating nonlinear circuits have appeared, mainly in the area of secure communications or ultra-wideband data transmission. In this lecture an introduction to chaos and its features is provided, together with applied chaos theory examples utilizing nonlinear circuits’ examples. Finally, chaotic synchronization and its application on secure communications and ultra-wideband (UWB) is discussed.

Biography: Dr. Stavros Stavrinides received his Physics Diploma, his M.Sc. in Electronics and his Ph.D. in Chaotic Electronics in 1996, 2003 and 2007, respectively; all from the Aristotle University of Thessaloniki. He currently serves as a Visiting Assistant Professor at the Department of Electrical and Computer Engineering, UCY in Cyprus. Dr Stavrinides has taught numerous topics in physics and electronics, in various institutions (such as the Aristotle University of Thessaloniki and Kavala Institute of Technology) for more than 14 years. His research interests include, non-exhaustively, the design of analog and mixed-signal electronic circuits, chaotic electronics and their applications, experimental chaotic synchronization, chaotic UWB communications as well as, measurement and instrumentation systems.

Integrating Green House Emission Costs in Life-Cycle Loss Evaluations

Department of Electrical and Computer Engineering

Title: Integrating Green House Emission Costs in Life-Cycle Loss Evaluations

Antonis Lazari
Ph.D. Student of the Department of Electrical and Computer Engineering
University of Cyprus

Wednesday, 17th October 2012, 17:00 – 18:30
Room KENTP. ΠΤΕΡ. – E113, Old Campus, University of Cyprus

Abstract: In the context of the continuous growth on power system investment and energy costs, the stakeholders are willing to strike a sense of balance between cost of purchase and cost of energy losses. Electric utilities are gradually interested in installing highly efficient equipment in their networks, so as to reduce the energy consumption. Hence, it is essential to rely on enhanced methodologies that could in detail evaluate the losses of electrical equipment/systems and their cost, in our case in transmission lines. European Commission strategies are encouraging communities towards more efficient and more sustainable energy solutions that will result in reduction of greenhouse gases (GHG) emissions in future years. Nowadays the reduction of greenhouse gas emissions is becoming a topical issue due to the growing concern for global warming and climate change. The actions that can immediately reduce GHG emissions and their cost, for an electric utility, are the use of energy efficient equipment and renewable energy sources. This presentation aims to provide an enhancement of a previous model for the evaluation of the Total Cost of Ownership (T.O.C.) that supports transmission lines by introducing environmental factors, i.e. GHG emissions and their cost. Efficient transmission lines need to be evaluated for losses by providing vital enhancements beyond the state of the art.

Biography: Antonis Lazari was born in Nicosia, Cyprus in 1988. He studied M.Eng. (Hons) in Electrical and Electronic Engineering and graduated in 2010 from the University of Bristol, UK. Since January 2011 he has been with the Department of Electrical and Computer Engineering, at the University of Cyprus as a PhD student in the field of Electrical Power Engineering. His research interests include Losses Evaluation in the light of increasing penetration of renewable energy generation.

 

 

 

Indices for Assessing the R.E.S Penetration in Transmission Networks of Isolated Systems

Department of Electrical and Computer Engineering

Title: Indices for Assessing the R.E.S Penetration in Transmission Networks of Isolated Systems

Alexandros Nikolaides
Ph.D. Student of the Department of Electrical and Computer Engineering
University of Cyprus

Wednesday, 24th October 2012, 17:00 – 18:30
Room KENTP. ΠΤΕΡ. – E113, Old Campus, University of Cyprus

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.

Biography: Alexandros Nikolaidis was born in Ptolemaida, Greece in 1986. He received his Diploma in Electrical & Computer Engineering from the Democritus University of Thrace, Greece, in November, 2010 and his MSc degree from the University of Cyprus in May, 2012. Since September, 2012 he is pursuing his PhD degree at the Department of Electrical and Computer Engineering of the University of Cyprus.

Real-Time Hand Tracking for Human-Computer Interaction

Department of Electrical and Computer Engineering

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.
