Groundbreaking Ceremony Held for New ECE Building by TOM MOONE
NEWS FOR ECE ILLINOIS ALUMNI AND FRIENDS WINTER 2011 Also in this issue: New Assured Cloud Computing Center to be established at Illinois Groundbreaking Solar Decathlon: Helping students and the world ceremony held Alumnus Michael McCorquodale is the first ECE Engineer for new ECE building in Residence Department of Electrical and Computer Engineering Breaking ground on the future Dear alumni and friends, I have good news! The dream of a new building for our department, after many years of planning and anticipation, is now becoming a reality. Last month’s groundbreaking of the new ECE building marks the beginning of a new era for our department, a department of global influence and impact, thanks to the excellence of its faculty and alumni. And it is this global impact that makes this groundbreaking special not only for our department, our college, our campus, and our university, but also for the state of Illinois, our nation, and the world. Our faculty and our alumni have been among the pioneers of the major technological innovations that are the bedrock of today’s computing and communication technologies. The marvel of the computing technology and the communications infrastructure we enjoy today, and its catalytic role in improving living standards around the globe, would not have been possible without John Bardeen’s invention of the transistor or Jack Kilby’s brilliant idea of the integrated circuit. These Nobel Prize-winning innovations by two giants of the ECE ILLINOIS community have been followed by many more groundbreaking advances by ECE faculty and alumni, advances that inspire and drive our quest for a sustainable future for all. -

An Abstract of A Variability Study of Y Dwarfs: A Spitzer Space Telescope Program by Jesica Lynn Trucks Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Doctor of Philosophy Degree in Physics with concentration in Astrophysics The University of Toledo August 2019 I present the results of a search for variability in 14 Y dwarfs consisting 2 epochs of observations, each taken with Spitzer for 12 hours at [3.6] immediately followed by 12 hours at [4.5], separated by 122{464 days and found that Y dwarfs are variable. We used not only periodograms to characterize the variability but we also utilized Bayesian analysis. We found that using different methods to detect variability gives different answers making survey comparisons difficult. We determined the variability fraction of Y dwarfs to be between 37% and 74%. While the mid-infrared light curves of Y dwarfs are generally stable on time scales of months, we have encountered a few that vary dramatically on those time scales. -

Our dataset incorporates publicly available radial velocities taken with the ELODIE and CORALIE spectrographs, HARPS, and Keck HIRES as well as previously unpublished HIRES velocities. We first quantita- tively assess the validity of the planets thought to orbit GJ 876 by computing the Bayes factors for a variety of different coplanar models using an importance sampling algorithm. We find that a four-planet model is preferred over a three-planet model. Next, we apply a Newtonian MCMC algorithm to perform a Bayesian analysis of the planet masses and orbits using an n-body model in three-dimensional space. -

Could evidence be buried in existing data? To recognize ETI, we first propose criteria discerning life from non-life based on thermodynamics and living systems theory. Then we extrapolate civilizational development to both external and internal growth. Taken together, these two trends lead to an argument that some existing binary stars might actually be ETI. Since these hypothetical beings feed actively on stars, we call them “stellivores”. We present an independent thermodynamic argument for their existence, with a metabolic interpretation of interacting binary stars. The jury is still out, but the hypothesis is testable with existing astrophysical data. Keywords: SETI, Dysonian SETI, Astrobiology, High energy astrophysics, High energy astrobiology, Living systems theory, Stars: binaries: general, Stellivore 1 - Introduction In 1960, Freeman Dyson proposed to search for extraterrestrial intelligence (ETI) by looking for infrared radiation emitted by an artificial biosphere covering a star (Dyson 1960). Unfortunately, despite some searches, the results are negative (Jugaku, Noguchi, and Nishimura 1995; Carrigan Jr 2009; Wright et al. 2014). We thus lack proof or even indication of ETI, a fundamental gap in our knowledge of the universe. -

Naval Engineering and Labor Specialization During the Industrial Revolution
Naval Engineering and Labor Specialization during the Industrial Revolution Darrell J. Glaser Department of Economics United States Naval Academy [email protected] Ahmed S. Rahman Department of Economics United States Naval Academy [email protected] January 2012 1 Abstract This paper explores the roles of capital- and technology-skill complementarities in labor allocation decisions within the U.S. Navy. During the latter 19th century the officer corps was highly specialized, and was split between groups of line and staff officers. This was also a time of dramatic technological changes which affected nearly every facet of naval opera- tions. Specifically, naval technological developments tended to be \engineering-biased," in that they raised the relative importance of engineer-oriented skills. This created a dilemma for the Navy, as it navigated the balance between the benefits of a specialized workforce implementing increasingly complex technologies with rising communication and coordina- tion costs. We first document the extent of capital- and technology-skill complementarities within the navy which fostered greater labor specialization. We then show how the Navy vitiated the specialized human capital of officers by blending the corps. The study offers in- sights into how an industry undergoing wrenching technological changes managed its labor and human capital allocation to help the U.S. become a world class naval power. • Keywords: skilled-labor complementarity, skill-replacing and skill-using technology, labor allocation • JEL Codes: J2, J7, N3, N7, O3 2 1 Introduction This paper explores the effects of capital- and technology-skill complementarities in the U.S. Navy. Specifically, we explore how such complementarities influenced task specialization and labor allocation during the latter 19th and early 20th centuries. -

Explaining the Mysterious Connection Between Physics and Mathematics by Reconciling the Unified Field and Anthropic Principle
Title - Explaining The Mysterious Connection Between Physics and Mathematics By Reconciling the Unified Field and Anthropic Principle Author – Rodney Bartlett Abstract – This is a copy of my entry in the latest essay contest conducted by the Foundational Questions Institute (FQXi). That contest restricts me to 25,000 characters, so I’ve added Notes to the end of the essay (FQXi allows the addition of notes but limits their length to much less than what I want to say). Other excellent essays in FQXi’s current contest will inform readers about the role of Fibonacci numbers and the Golden Ratio in nature [14], as well as referring to the book “Our Mathematical Universe” [9] and the use of pi in a science-fiction book by astronomer Carl Sagan to show that “the universe was made on purpose” [15]. Rather than merely repeat the other essays’ wisdom, I’ll take a different approach. I hope my approach will be novel and original, but only time will reveal where it may lead. I want to show that you can combine the topology (rubber- sheet geometry), binary digits and E=mc^2 of maths with the matter, energy and forces of physics to 1) explain dark energy and dark matter, 2) open up the whole universe and all time to human exploration and creation, 3) show that there’s an infinite, eternal cosmos (not a multiverse) beyond our observable universe, 4) unify gravitation with electromagnetism, the other fundamental forces, and the physical universe; and 5) reconcile the anthropic principle with the unified theories of physics (via a strong version of that principle - that a direct link exists between human existence and the actual form of the laws of nature).
