Title:"Smart Cities - Challenges and Opportunities"
Abstract- Good evening, John. Just a reminder that you haven't had five to seven servings of fruits and vegetables today,'' says the fridge. ``I'll be happy to cook some vegetables for you,'' adds the oven. ``Yes, and in the meantime, perhaps you can jog for 20 minutes,'' chimes in the treadmill. It is the year 2025, and our lives are run by smart machines. Future smart cities will exploit powerful technologies such as artificial intelligence, robotics, and autonomous vehicles to improve the quality of life and reduce the burden of urban living on humans. As evolving, (almost) living organisms, smart cities will afford their citizens comprehensive health monitoring and preventive health care, distributed work environments with telepresence, and vast communication networks. This presentation examines possible trends in the development of smart cities.

Abstract: Communication of data on electrical wires between chips is fast gaining prominence in the electronics industry. Because most of the components of the transmitter and the receiver of such links are analog, rather than digital, they don’t benefit as much from Moore’s law. On the other hand, the need to transmit data ever faster calls for higher rates of transmission over existing electrical wires. Since in this type of communication noise is highly frequency dependent, higher transmission rates lead to much higher noise, and therefore a much higher growth of power consumption than linear. The industry has long recognised this problems as the “Interconnect bottleneck”. Fundamental solutions to this important problem have remained elusive, however.
A look at the capacity of these channels reveals that today we are only transmitting at anywhere between 1% to 4% of the capacity. Therefore, at least on the surface, there is a lot to be gained by applying methods from communication theory to this problem. However, unlike many other systems such as wireless, DSL, satellite, or optical communication, the constraints on the chip-to-chip communication system are very different: transmission rates are typically 1000 times those encountered in wireless communication. On the other hand, the energy consumed for the transmission and recovery of each bit is about 1000 times less than what is customary in wireless. Also, latency requirements are extremely stringent, allowing only latencies up to very few nanoseconds. Therefore, it is not possible to use fancy processing methods.
In this talk I will introduce a new modulation scheme for chip-to-chip communication which we call chordal codes. These codes are somewhat reminiscent of spatial MIMO systems, and provide a first step towards a better utilisation of the available communication bandwidth between chips. Current implementations of systems based on these codes show a large reduction of total power of the communication PHY and a large increase of the communication speed compared to other classical system.

Abstract: When Smith, Pendry and others started tinkering with split-ring resonators (SRR) for realizing double negative media, little did we know then that these earlier ground breaking works ushered the beginning of a completely different perspective on designing of all types of electromagnetics-based systems. The SRR, or any other resonator that has dimensions much smaller than the wavelength were used as the building blocks for single and double negative media and even near-zero media. While these exotic media enabled cloaking and design of dispersion-controlled media, the applications were largely limited. The concept of a building block, however, might hold the key to a much larger class of designs and applications. Back in the seventeenth century, Huygens conceived the idea of elementary sources as forming the radiated or scattered field. His extraordinary perception of the mechanism of the wave phenomenon preceded the full-fledged development of Maxwell equations by more than 150 years. While Huygens work was an attempt to understand the wave phenomenon through analysis, we pose the question of whether we can extend the concept of building blocks or elementary sources to synthesize electromagnetics based radiating systems. If all things in nature are composed of identical building blocks, can we conceive of a similar construction of electromagnetics systems in general?
In this talk, I will focus on the importance of understanding what is meant by metamaterial, metasurface particles or electrically-small resonators in general. Unlike building blocks used for other physical systems that are not founded on the action-at-a-distance phenomena, the electrically-small resonators, or electromagnetic Legos are more intriguing as their strong coupling needs to be tailored to ensure their desired operation. Several new designs of electromagnetics systems from lenses, to sensors and antennas will be discussed in details covering a broad range of activities conducted in my research group at Waterloo. Focusing on the concept of a building block will naturally reignite strong interest in understanding the fundamental physical phenomenon of radiation and hopefully would lead to asking important questions that were considered of secondary importance in earlier times.

Title:"Information At The Core Of Creation"
Abstract: The purpose of this talk is to describe the role of information and its processing apparatus in various and biological systems such as second law of thermodynamics, photosynthesis, black-holes and universe. I begin with a discussion on the relation between logical information (Shannon) and physical information (boltzman) and argue that information can be lost, but it cannot be destroyed. Taking advantage of general relativity, Special relativity and quantum mechanics, I'll discuss that the universe can be realized as a computational machine with 10120 operations on 1090 bits over its 10 billion years of existence. I'll also describe a fascinating process namely quantum walk as oppose to random walk , in quantum biological systems such as photosynthesis and describe the fundamental algorithm based on quantum walk that miraculously speeds up the exciton energy transfer, created by absorbing a photon to creation-center.
I will close my discussion on a philosophical note that the creation of "information" may indeed have superseded the creation of physical, chemical and biological processes and systems.
