"The 150th birthday of Maxwell Equations"
10:00 am, Towne 337
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!

Professor, University of Wisconsin-Madison
"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

"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.

"How Complex Endeavors go Wrong"
Read the Abstract and Bio

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.

Managing Architect, Altera
"Subversive Innovation"
11:00-12:00 pm, Towne 337
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.

"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.
