"Electronics on anything: How Thin Film Electronics can Instrument the World"
11:00-12:00 pm, Singh Center Glandt Forum

Read the Abstract and Bio

Abstract: Silicon electronics have revolutionized the processing and handling of information. The high temperatures required to create crystalline silicon devices, however, has limited the application of crystalline silicon to sensing systems that work in a small and mechanically rigid form factor. The development of inorganic and organic thin film electronics has launched a second revolution in electronics, granting the ability to process electronically active materials at low temperatures. This has allowed for two exciting opportunities: the ability to build electronic devices on the same size scale as the systems they interact with, and the ability to integrate electronic materials on a range of substrates including electronically active and flexible materials. Our group has been working on the hybrid integration of organic semiconductors and SLS laser-recrystallized silicon with active substrates to implement a range of new functionalities. In this presentation, I'll show how thin film electronics and the hybrid integration enabled by new semiconductor systems and process options allows for active and spatially localized control of systems that are typically used in a single element format. These approaches unlock new applications in healthcare, sensing, displays, and communications.

11:00-12:00pm, Raisler Lounge, Towne 225

Read the Abstract and Bio

Abstract: The present day technology falls short in offering autonomous mobile robots that can function effectively and efficiently under unknown and dynamic environmental conditions. Insects and canines, on the other hand, exhibit an unmatched ability to navigate through a wide variety of environments and overcome perturbations by successfully maintaining control and stability. In this talk, Dr. Alper Bozkurt will present how neural stimulation and physiological monitoring systems can be used to wirelessly navigate cockroaches and train dogs to allow for cyber-enabled working animals. These biobots would potentially assist humans in environmental sensing and search-and-rescue applications to pinpoint hazardous material or to find earthquake victims. This is one of the on-going efforts under Integrated Bionic MicroSystems Laboratory (iBionicS Lab) which has a vision to introduce conceptually novel neural engineering methodologies and wearable devices to interface biological organisms with synthetic systems
towards the next generation bionic cyber-physical systems. Such cyber-physical systems would be one of the building blocks of the new era where everything is inter-connected through the Internet of Things.

"In situ TEM Observation Using Active MEMS Devices"
1:30-2:30 pm, Singh Center Glandt Forum

Read the Abstract and Bio

Abstract: My research group has investigated MEMS (micro electro mechanical system) fabrication and microactuators since 1986. Recently, we inserted and operated MEMS devices in the specimen chamber of the transmission electron microscope (TEM). We conducted the tensile and shear testing, and the heat transfer measurement of nano junctions while the junctions were in situ observed by TEM. The tensile testing of a silicon junction of a few nm in diameter showed its extraordinary large plastic deformation. The shear deformation of a silver nano junction exhibited series of sub-nm steps correlated with the crystalline spacing of the material; this is like a miniaturized version of stick-slips during frictional motion. Furthermore, the heat transfer through a short and thin, both in a few nm, silicon junction was much higher than the bulk value because of ballistic heat transfer. Also we have built a MEMS liquid cell in which the growth of a gold electrode by electroplating was observed in real time.

"Fundamental Limitations in Multiagent Coordination"

Read the Abstract and Bio

Abstract: The goal in networked control of multiagent systems is to derive desirable collective behavior through the design of local control algorithms. The information available to the individual agents, either through sensing or communication, invariably defines the space of admissible control laws. Hence, informational restrictions impose constraints on achievable performance guarantees. The first part of this talk will provide one such constraint with regards to the efficiency of the resulting stable solutions for a class of networked resource allocation problems with submodular objective functions. When the agents have full information regarding the resources, the efficiency of the resulting stable solutions is guaranteed to be within 50% of optimal. However, when the agents have only localized information about the resources, which is a common feature of many well-studied control designs, the efficiency of the resulting stable solutions can be 1/n of optimal, where n is the number of agents. Consequently, such schemes in general cannot guarantee that systems comprised of n agents can perform better than a system comprised of just a single agent. The second part of this talk will focus on identifying how augmenting the information to the agents can impact achievable performance guarantees.  While providing the agents with additional information can lead to control designs with improved efficiency guarantees, it turns out that such gains frequently come at the expense of the underlying convergence rates.  Hence, there is an apparent tradeoff between short-term and long-term performance guarantees in multiagent systems and we will characterize this tradeoff in a simple distributed graph coloring problem. The last part of this talk will present some preliminary results on robust mechanisms for social coordination.

"Capturing Light-Fields on Chip: lens-less 3-D imaging in standard CMOS"

Read the Abstract and Bio

Abstract: Whereas traditional image sensors map the intensity of light at a particular plane, significantly more information is present in a field of light rays. In particular, by mapping the distribution of incident angle in a scene, light-field imaging permits passive extraction of 3-D
structure from a single frame.  I will present a new class of pixel, the “angle-sensitive pixel” (ASP) built in a standard CMOS manufacturing process.  ASPs use pixel-scale diffraction gratings built from metal interconnect layers to generate a strongly angle-sensitive light response.

An appropriately chosen mosaic of ASPs provides a much richer description of incoming light and does so in a computationally compact format, similar to the Gabor filters used in many image-processing applications.  I will discuss several applications for arrays of ASPs, including digital light-field photography, lensless far-field imaging, and near-field lensless 3-D imaging of fluorescent microscale sources.

"Neuroengineering the Next Decade"

Read the Abstract and Bio

Abstract: One of the grand challenges in neural engineering is the lack of reliable low-power miniaturized wireless telemetry. Wires affect behavior and fundamentally alter measurements. Wireless capability doesn’t broadly exist today for wide neuroscience community, at rates and channel counts needed, compromising scientific discovery and therapeutic outcomes. Biosignal transducer systems require not just sensing, but also actuation, and closed-loop control.

This talk will address the above challenges, starting with devices for translational animal studies, including wireless neural activity monitoring of brain-injured rats and initial work towards body-powered devices. Findings from animal studies provide key insights into the design of heavily size/energy-constrained wireless neuromodulation technology for human memory restoration.

"Problems in Biologic Imaging: Opportunities for Signal Processing"
12:00-1:00 pm, Towne 337

Read the Abstract and Bio

Abstract: In recent years, the focus in biological sciences has shifted from understanding single parts of larger systems, sort of vertical approach, to understanding complex systems at the cellular and molecular levels, horizontal approach. Thus the revolution of "omics" projects, genomics and now proteomics. Understanding complexity of biological systems is a task that requires acquisition, analysis and sharing of huge databases, and in particular, high-dimensional databases. Processing such huge amount of bioimages visually by biologists is inefficient, time-consuming and error-prone. Therefore, we would like to move towards automated, efficient and robust processing of such bioimage data sets. Moreover, some information hidden in the images may not be readily visually available. Thus, we do not only help humans by using sophisticated algorithms for faster and more efficient processing but also because new knowledge is generated through use of such algorithms. The ultimate dream is to have distributed yet integrated large bioimage databases which would allow researchers to upload their data, have it processed, share the data, download data as well as platform-optimized code, etc, and all this in a common format. To achieve this goal, we must draw upon a whole host of sophisticated tools from signal processing, machine learning and scientific computing. I will address some of these issues in this presentation, especially those where signal processing expertise can play a significant role.

"Future Directions for Silicon Radio Frequency Electronics"
Read the Abstract and Bio

Abstract: Growth in mobile communication and computing technologies over the past two decades has been driven by innovations in system architectures, software technology, and silicon integration. Analog/RF circuit innovations relevant to developing more efficient infrastructure, conserving energy, and delivering better health care are described in this talk.

Advanced CMOS is the enabling technology for radio frequency circuits designed into almost all low-cost electronic products sold today. The feat of doubling the number of transistors on a silicon IC every 18 months is projected to continue until we reach a gate length approaching 5nm (projected in ~ 2020-2030 by the ITRS). However, continued scaling presents the designer with different transistor behavior with each generation, as the transistor’s electrical characteristics are affected by evolutionary changes in fabrication. Circuit and systems designers must therefore develop scalable designs that can adapt to a dynamic technology platform.

Three examples from recent research into the design of adaptive, wideband, and scalable high-frequency electronics aimed at emerging applications are described in this talk. Wireless silicon sensors capable of measuring position and velocity accurately are needed for intelligent traffic managment schemes. A recently developed mm-wave FMCW radar transmitter IC incorporates the phase-locked loop, digitally controlled oscillator, PA, and calibration circuits in 65nm CMOS. The ADPLL performs autonomous calibration and closed-loop DCO gain linearization in order to output a GHz-speed triangular chirp with high sweep linearity. The transmitter achieves excellent in-band/ out-of-band phase noise performance, ultra-low reference spur levels (-74 dBc), and is scalable to future technology nodes. Scenarios for improving health care often require low-power radios to monitor patients remotely. In the second example, a low-power, autonomous FM ultrawideband transceiver and power management unit that transfers data reliably at 100kbit/s and includes full on-chip digital calibration of the transceiver is described. Finally, fiber-optic technologies in the internet backbone are migrating towards coherent modulation schemes to increase data throughput. A silicon electronic driver capable of producing the 6Vp-p output required to drive a Mach-Zehnder optical modulator is presented. Based on a distributed amplifier architecture, the novel input interface enables performance competitive with III-V semiconductor technologies (i.e., 15ps rise-fall times at 10Gb/s) but on a silicon IC platform capable of full transceiver integration.

Bio: John R. Long received the B.Sc. in Electrical Engineering from the University of Calgary in 1984, and the M.Eng. and Ph.D. degrees in Electronics from Carleton University in Ottawa, Canada, in 1992 and 1996, respectively.

Abstract: In the 1980s Model Predictive Control (MPC) became the algorithm of choice in the process industries for demanding multi-variable applications involving constraints. Today's vastly more powerful computational resources and a series of new algorithms have made these tools suitable for problems of essentially any size and time scale. I will describe the road taken and illustrate the effectiveness with industrial examples from the automotive and power electronics domains and the industrial energy sector. In the final part of the lecture I will suggest topics of future research.

"Subversive Innovation"

Read the Abstract and Bio

Abstract: Being effective in an engineering organization is not easy. In this talk, I will share my observations on why it is hard and offer my advice on how to be effective without losing your mind, your enthusiasm, or your job. I call this "subversive innovation" because the machinery of a technology enterprise is frequently and almost specifically constructed to prevent innovation. If you don't get permission to do something innovative, sometimes those innovations have to be subtle, hidden or disguised.

I put this talk together as part of a technical leadership series at Altera in 2013 and have adapted it for a broader audience. I may offer some vague examples from my experience in Field Programmable Gate Arrays, but most of the discussion is applicable to any large technology enterprise. I have tried to make the talk entertaining and applicable, and would love to collect more specific ways to be subversive innovator.

Bio: Herman Schmit received his undergraduate degree from the Moore School of Electrical Engineering in 1987. For 4 years, he resisted the temptation to swipe a tube from the ENIAC, which was left like junk in the hall of the Moore building. He received his PhD from Carnegie Mellon in 1995. From 1995 to 2003 he was an Assistant and Associate Professor at CMU. Since 2003 he has worked in Silicon Valley, first at two semiconductor startups, and most recently as the FPGA fabric architect at Altera Corporation.

Abstract:Why was Admiral Nelson able to win at Trafalgar, while, almost two hundred years later, the United States was unable to rescue its hostages from Iran? An important part of the answer to this question lies in the management, or “Command and Control,” of complex endeavors. We examine 20 situations, from the First World War to the present time, including military operations and responses to natural disasters and terrorist attacks. All have been characterized as experiencing ‘Command and Control failures.’ We identify three categories of failures: (1) failures attributable to a priori structural defects in enterprise approach, or a mismatch between the enterprise approach and the mission; (2) failures attributable to an inability to communicate, because of shortfalls in technology and system design, or because of physical impossibility; and, (3) behavioral failures to communicate or interact. Different enterprise approaches, of varying degrees of centralization, have different failure propensities. For example, a collective that is distributed, but not properly integrated, may sometimes be more adversely affected by communication failures than a traditional hierarchy. Traditional hierarchies, on the other hand, may be stymied by overly constrained information flows and patterns of interaction. Enterprise agility, meaning the ability to reconfigure the enterprise and its approach to meet the needs of the problem at hand, is paramount.

"FPGA Architecture and Design"
2:00-3:00 pm, Towne 337
Read the Abstract and Bio

Abstract: Field-Programmable Gate Arrays are flexible hardware devices that fall between dedicated hardware devices such as an ASIC and software programmable devices like a CPU or GPU. FPGAs are used by a wide range of end applications in communications and networking, radar, industrial control devices, and high-performance compute acceleration. In this talk I will overview the architecture of an FPGA - the logic, memory and I/O blocks, programmable routing for joining them together, and some of the interesting software algorithms used for programming FPGAs. I will show some of the more interesting recent changes and trends in FPGAs and some of the challenges going forward for FPGAs and all forms of integrated circuits. Finally, I will spend some time describing the role of industrial research and development for those who are interested in careers in FPGAs or related fields of hardware and software design.

"Active Crowdsourcing"
Read the Abstract and Bio

Abstract: Human experts are crucial to data analysis, but may often be the information bottleneck in data analysis tasks. I will discuss new theory and algorithms that enable machines to learn efficiently from human experts, using a minimal amount of human interaction. The models so learned then inform the understanding of human cognition and the design of better algorithms for data processing. I will focus on active learning from human experts based on adaptively crowdsourcing training data o a pool of people. Rather than randomly selecting training examples for labeling, active crowdsourcing sequentially and adaptively selects the most informative examples for human evaluation, based on information gleaned from previous human feedback. By making optimal use of human expert judgment, these active learning method can speed up the training of a variety of machine learning algorithms. TBD

"The 150th birthday of Maxwell Equations"

Read the Abstract and Bio

Abstract: In this Colloquium the 150th birthday anniversary of Maxwell Equations is celebrated, and their accomplishments over these 150 years commented. The presentation has been designed for a scientific audience, but not necessarily familiar with electromagnetic phenomena.

In the late seventeenth and eighteenth century, mysterious electric and magnetic different phenomena were exciting curiosity of people, and also interest of some scientists. Their investigation, essentially performed in France and UK, was formalised by two laws, Biot & Savart and Faraday equations.

And then James Clerk Maxwell entered in the arena: a dark penumbra suddenly changed to brilliant light, theoretical results from his new equations were experimentally confirmed, and successive applications implemented.

This Colloquium presents the romance of Maxwell equations, created and not derived from preliminary experiments, and the successive steps of their usage for a number of applications that changed, and are still changing our physical and social life. At the end of the Colloquium, a just one minute additional comment is added: no detail is given here, to hide a thrilling conclusion!
