Brief Biography: Alan Mickelson received a PhD in Electrical Engineering with subject minor in Physics from California Institute of Technology Pasadena, CA, was a Postdoctoral Fellow in Byurakan, Armenia and spent four years at the Norwegian Institute of Technology as a Postdoctoral Fellow and staff member of the Elektroni laboratoriet before coming to Boulder. Alan’s primary research focus is optical nanotechnology, most recently silicon photonics for computer interconnections. Alan had previously worked in integrated optical materials, integrated optical devices for microwave applications, semiconductor laser stabilization as well as fiber optics.
Abstract: Silicon photonics is the most effective technology for moving digital signals back and forth from circuits to optical fibers. Present day applications of silicon photonics are described with some speculation as to what the future may bring. Specific realizations of silicon photonic chips are discussed to introduce the technology. The origins of the integrated optics in silicon are reviewed. The present state of internet scale data communication is discussed to explain the place of silicon photonics devices in data centers. Discussion turns from data centers to high performance computing to big data and onto sensor fusion in the internet of things. Some attention is placed on production of silicon photonics components with a focus on prediction of future development.

Abstract: Establishing a microwave link over sea is fraught with many challenges. Conventional microwave links are limited by line-of-sight distances. Beyond line-of-sight technologies are limited to satellite based solutions or troposcatter based solution. Luckily nature has provided us with evaporation duct over the sea water. The climatology suggests that the duct exists for fairly high percentage of time. We will explore in this presentation the possibility of suitably designing link.

Communication in IoT - Internet of Things (IoT) consists of smart devices that cooperate and communicate among one another to sense, collect and exchange data. The need for communication depends on the applications such as personal information, industry, transportation, logistics, healthcare smart environment etc. The Internet of Things (IoT) technology needs a standardized way of connecting devices to each other and to internet. WiFi or WLAN technology has been playing a crucial role in machine to machine communication. The main demands of IoT communication are ubiquity and reliability. Wireless IoT employ different wireless communication technologies and protocols to connect to each other. They may use short range standard network protocols like IPv6 Low Power Wireless Personal Area Networks, ZigBee, Bluetooth Low Energy, Z-Wave and Near Field Communication (NFC). Low Power Wide Area Network (LPWAN) standard protocols like SigFox and Cellular are also employed. In this lecture, a review of the existing communication techniques will be discussed.

Recent Challenges in Renewable Power Conversion and Grid Interface - World-wide depleting fossil fuel energy reserves and environmental concern are the prime reason why power engineers are shifting towards renewable energy generation. Bulk power generation from renewable energy resources to supply clean and controlled output is an important requirement. In particular, solar and wind power generation accounts for nearly 1.5 % and 2.3 %, respectively, of the net global electricity generation. Due to intermittent nature of renewable energy sources, there is need of energy storage and grid interconnection. Utilizing energy from such distributed energy resources (DER) requires judicious choice of their ratings, locations and control, else it may deteriorate the overall grid system performance, which includes real and reactive power flow, power losses, unbalanced voltage profiles, voltage sag/swell, harmonic distortions etc. Other challenges with DERs involve varying load power demand, instantaneous active and reactive power balance, converters control etc. in grid connected and islanded mode of operation. Challenges with power conversion involves various technology aspects such as extraction of maximum power from the renewable energy systems, DC-DC converters, and inverter control to supply clean and stable AC power. These involve power coordination and control of single and three phase converters in distributed energy resources. Efficient energy storage units and their controls are required to accomplish the power balance. The system study with the renewable power conversion could be further extended for operational scenarios involved in AC/DC microgrids.

Software Defined Wireless Fog-Mesh: Towards a Communication and Computation Infrastructure for Smart Environments - Recently, the ideas of fog and edge computing have been proposed to move the computation near the end devices that produce or consume data. These ideas can easily be utilized for IoT based smart environments. Generally, the practical implementations of smart environments rely heavily on cloud for data processing, analytics and decision making. The data captured by IoT devices is transferred via Internet towards cloud data centers which may introduce unwanted delay in real time scenarios. If we go by the popular predictions regarding number of active IoT devices, the best effort service provided by Internet may become a huge bottleneck. Further, to make the environment IoT friendly, a scalable communication infrastructure is needed which should be cost effective and can sustain the ever increasing number of devices. In this talk I would provide the details of our attempts to build a wireless mesh based fog computing infrastructure for IoT enabled smart environments. The important aspect of our methodology is that it can quickly be deployed for use-cases where smart environment is needed on a temporary basis, such as rock concerts, fairs, sporting events, etc. I would present the challenges we faced while implementing a small scale prototype test-bed where mesh routers are made to act as fog nodes. The talk would also highlight the usage of Distributed Hash Table (DHT) for resource discovery among fog nodes . Also, some directions would be provided to utilize Software Defined Networks (SDN) concepts to dynamically adjust the policies of underlying wireless network according to the context.

Low Carbon Concretes for Sustainable Constructions - India produces more than 100 million cum of concrete in organised sector. Most of the Concrete are rich in cement, either made with Ordinary Portland Cement or small replacements with Fly Ash. Still the preference is towards Normal Portland Cement Concrete. These concrete has high carbon footprints and are un-sustainable. The study explores the possibility of use of GGBS as cement replacement and other steel slag as aggregate replacements to reduce the carbon footprints of various structural concretes. It has been observed that carbon footprints of concrete can be reduced by more than half with these possibilities retaining structural properties and improving the durability characteristics of at the same time.
