Lecture #1:
Electromagnetic Macro Modeling of Propagation in Mobile Wireless Communication: Theory and Experiment
Abstract:
The objective of this presentation is to illustrate that an electromagnetic macro modeling can properly predict the path loss exponent in a mobile cellular wireless communication. Specifically, we illustrate that the path loss exponent in a cellular wireless communication is three preceded by a slow fading region and followed by the fringe region where the path loss exponent is four. Theoretically this will be illustrated through the analysis of radiation from a vertical electric dipole situated over a horizontal imperfect ground plane as first considered by Sommerfeld in 1909. To start with, the exact analysis of radiation from the dipole is made using the Sommerfeld formulation. The semi-infinite integrals encountered in this formulation are evaluated using a modified saddle point method for field points moderate to far distances away from the source point to predict the appropriate path loss exponents. The reflection coefficient method can also be derived by applying a saddle point method to the semi-infinite integrals and it is shown not to provide the correct path loss exponent. The various approximations used to evaluate the Sommerfeld integrals are described for different regions. It is also important to note that Sommerfeld’s original 1909 paper had no error in sign. However, Sommerfeld overlooked the properties associated with the pole. Both accurate numerical analyses along with experimental data are provided to illustrate the above statements. Both Okumura’s experimental data and experimental data taken from different base stations in urban environments at two different frequencies will validate the theory. Experimental data reveal that a macro modeling of the environment using an appropriate electromagnetic analysis can accurately predict the path loss exponent for the propagation of radio waves in a cellular wireless communication scenario.
Lecture #2:
Physics of Multiantenna Systems and Their Impacts on Wireless Systems
Abstract:
The objective of this presentation is to present a scientific methodology that can be used to analyze the physics of multiantenna systems. Multiantenna systems are becoming exceedingly popular because they promise a different dimension, namely spatial diversity, than what was available to the communication systems engineers: The use of multiple transmit and receive antennas provides a means to perform spatial diversity, at least from a conceptual standpoint. In this way, one could increase the capacities of existing systems that already exploit time and frequency diversity. In such a scenario it could be said that the deployment of multiantenna systems is equivalent to using an overmoded waveguide, where information is simultaneously transmitted via not only the dominant mode but also through all the higher-order modes. We look into this interesting possibility and study why communication engineers advocate the use of such systems, whereas electromagnetic and microwave engineers have avoided such propagation mechanisms in their systems. Most importantly, we study the physical principles of multiantenna systems through Maxwell’s equations and utilize them to perform various numerical simulations to observe how a typical system will behave in practice. There is an important feature that is singular in electrical engineering and that many times is not treated properly in system applications: namely, superposition of power does not hold.

Speaker #1:
Prof. Marco Liscidini, Department of Physics, University of Pavia, Via Bassi 6, Pavia, Italy
Abstract:
The drive to reduce the size of optical systems has led to a transition from bulk-crystal optics to integrated devices, and to the improvement of conversion efficiencies in nonlinear optical processes While often designed with the enhancement of a classical nonlinear optical process in mind, these integrated systems will also enhance the corresponding quantum nonlinear optical process. But is there a simple connection between the efficiencies of these two types of processes? Can one infer anything about quantum processes from classical experiments? In this talk we will show that indeed the results of classical experiments allow for an accurate prediction of quantum correlated photon-pair generation efficiencies, opening a path to move from classical to quantum nonlinear optics in integrated photonic structures.

Speaker #2:
Prof. Winnie Ye, Department of Electronics, Carleton University, Ottawa, Ontario, Canada
Abstract:
Silicon based photonics has been under great scrutiny in recent years due to their potential for making highly compact monolithic integration of multifunctional electronic and photonic devices on the same substrate. The most popular platform is the high index contrast silicon-on-insulator (SOI) system. The high refractive index contrast between the silica cladding and the silicon waveguide core facilitates the confinement and guiding of light in structures within submicron or nanometer dimensions. In addition, the mature silicon microfabrication technology establishes a firm foundation for making low-cost and compact integrated photonic devices. A wide range of active and passive optical devices has been realized on the SOI platform. The applications of these devices can be found in high-speed communications, health industry, chemical and biological analysis, environmental monitoring, optical interconnects, and renewable energy. This talk will describe the state of the art silicon based components and systems that are reported in the literature, as well as the on-going project at Carleton University.

Abstract:
The Smart Grid represents a clear step forward in improving power generation, distribution, consumption. Indeed, the Smart Grid is a digitally enabled electrical grid that gathers, distributes, and acts on information about the behavior of all participants (suppliers and consumers) in order to improve the efficiency, importance, reliability, economics, and sustainability of electricity services. In this scenario, communications gain a central point as a key enabling technology in supporting the “intelligence” of the system. Nevertheless, the area of communications and associated knowledge can even play a greater role, in supporting modeling, simulation and design of the next generation power grid. The seminar aims at providing an overview of the concept and architecture of the Smart Grid, focusing on the contributions of the communications community in terms of communications infrastructure and methodologies. Sample scenarios will be presented to illustrate the relevance of communications in the power grid .

Abstract:
Computers and information technology are proving themselves as energy-hungry partners in a society with carbon emission issues to be resolved. Video coding is a very computation-intensive, energy-demanding task. We approach green computing applied to video by setting task parameters in order to minimize energy consumption for a given performance. We applied the concept to H.264/AVC video coding, showing that one can substantially reduce energy consumption at the expense of a small rate-distortion (RD) performance penalty. We used a state-of-the-art implementation, x264, for tests and show RD results for comparisons and discussions.

Abstract DL1: Many-Core Chips: The New High-Performance Computing Platform
Sacling as we know it is taking a different direction from the last three decades. Chips with tens of billions of transistors and hundreds of cores are expected to be the future of scaling. These chips will achieve performance through parallelism and application specific optimized cores. This trend will use superior technologies to integrate more cores on a chip rather than to push the frequency envelope as in the past. It is expected that every aspect of design and analysis will need to be modified to accommodate this new platform and trend. There is a clear need for new CAD tools and design methodologies that are very different from existing tools in both their focus and scope. This talk will delve into the specific challenges with respect to both design and CAD that is required for these many core chips. The talk will also provide an overview into the market and technology factors guiding and driving this trend. Attendees will be provided with insight into both present and future research vectors to support this nascent exponential.
Abstract DL2: Challenges for Electronics Design in the Nano-Scale
Semiconductor technologies exhibited explosive growth in complexity and speed over the last two decades. Since the early 1980s, the device sizes have scaled down from few micrometers to tens of Nano-meters and the operating frequencies have increased from a few megahertz to several gigahertz. Also, the spacing between devices and interconnect have dramatically decreased due to the continuous scaling down of the technology feature size. These trends have led to issues and challenges in the design and analysis of high performance integrated circuits that previous generations did not exhibit. Most of these issues are at the circuit and interconnect (physical) levels. Also, these issues are expected only to increase in importance in future generations of integrated circuits. This talk will overview the most important challenges for electronics design in the nano-scale.

Abstract:
Energy is one of the top priorities in the world and smart grids are the centerpiece of this energy focus. Grid design, control and stability are the main objectives of smart grid technology in order to enhance the voltage stability of electric power distribution systems during faulty conditions and disturbances. Analysis and benefits of implementing smart grids based on multi-agent systems (MAS) show that it is a suitable technology for the complex and highly dynamic operation of a power system network. The existing power grid suffers from the lack of pervasive and effective communications, monitoring, fault diagnostics, and automation control, which further increase the possibility of a region-wide system breakdown due to the cascading effect that can be initiated by a single fault. Currently, for the power system, voltage control systems are centralized and operated through a central computer which supervises the output of all generators and adjusts optimally the voltage set points of these generators. This centralized regulation algorithm must know the whole network configuration and therefore for a large-scale power system, it may become difficult to perform a centralized control system. This motivates us to study and find efficient and secure voltage control mechanism in a power system by identifying the most appropriate controls based on decentralized and distributed control. This presentation firstly presents a definition and vision of the smart grid and its key areas including: Sensing and Measurement, Advanced Control Methods, Advanced Components and Integrated Communications. Secondly, an optimal electrical network graph partitioning technique is presented that divides a power network into appropriate regions to eventually prevent the propagation of disturbances and minimize the interaction between these regions. The optimized number of partitions is found based on the bus voltage sensitivity to the disturbances being applied to the loads in each region. A number of representative buses which are labeled as pilot buses are established and these are identified in each region displaying the critical point for secondary voltage control. The graph theory applied to this situation has the ability to simplify and decompose large connected power networks.
