INSTRUCTION SET ARCHITECTURE AS A LEVER FOR BETTER SECURITY, PERFORMANCE AND EFFICIENCY IN GENERAL PURPOSE PROCESSORS In general purpose processors, the instruction set architecture changes little over time, to maximize software compatibility. In this talk, I make the case that abandoning that approach can provide big gains in…

NANO-PHOTONICS, PLASMONICS, AND MEMRISTOR We have enjoyed the great successes of “Moore’s law” for more than four decades. They have mainly been fueled by the semiconductor industry. Although the end of the roadmap may be getting closer, it is just the start of a new era when we will leverage the billions of dollars that have been…

MINIATURIZED SOURCES OF ULTRASHORT OPTICAL PULSES AND HIGH SPECTRAL PURITY MICROWAVE SIGNALS A train of ultrashort optical pulses is comprised of a large number of laser tones oscillating synchronously. This equally-spaced array of frequencies, called an optical frequency comb, has found applications in the generation of high…

Nano-Optics for Highly Localized EM Fields and Some Applications This presentation describes studies of optical phenomena at the nanoscale for coupling electromagnetic waves into bright, sub-diffraction-limited spots. In particular, we investigate optical and infrared antennas designed to strongly resonate with radiation. The gain…

UAVs vs. Natural Autonomous Vehicles (NAVs) -- Are We Closing the Gap? There have been many significant advancements in UAV technology over the past 10-15 years.  In this presentation, we will step back and evaluate how well we are really doing in this area by comparing performance of UAVs with those of Natural Autonomous Vehicles…

Sparse Sampling for Active Learning of Multi-Source and Multi-Modal Environments Consider a field of interest from which you can only collect a few observations.  From these observations, we wish to find a target's location. Such a problem arises in military surveillance, environmental monitoring, cyber-security, medical diagnosis…

Unstructured (Big) Image Data Challenges Multimodal, unstructured data is ubiquitous: from consumer devices such as smart phones to scientific imaging, we encounter this data constantly, everywhere. The data is voluminous, accounting for a significant part of the digital data (one could speculate this to be >90%) generated…

Analysis and Design of Large Multi-Agent Swarms Through Continuum Approximations Self-organization is a pervasive phenomenon in nature, which has inspired the development of multi-robot systems that can mimick their biological counterparts. As we consider larger groups of robotic swarms, new theoretical challenges appear that are…
