Solitons, Self-Induced Transparency,
and Modelocking in Quantum Cascade Lasers

href="http://www.cs.umbc.edu/people/faculty/sergei-nirenburg/">Professor Curtis Menyuk
University of Maryland, Baltimore County

1:00-2:15pm Friday, 18 March 2011, ITE 227, UMBC

Standard semiconductor lasers operate in a limited wavelength range, below about 4 microns. Quantum cascade lasers (QCLs) that operate in the mid-IR and far-IR have important applications to medicine, environmental sensing, and national security. While short pulse lasers (~100 fs) are available for standard semiconductor lasers, that is not the case for QCLs. Standard passive modelocking is hard to do in QCLs because of their long coherence times and short gain recovery times. We propose a fundamentally different approach, based on the self-induced-transparency (SIT) effect, that turns these weaknesses into strengths. Solitons, modelocking, and SIT are all reviewed at the beginning of the talk.

Curtis R. Menyuk was born March 26, 1954. He received the B.S. and M.S. degrees from MIT in 1976 and the Ph.D. from UCLA in 1981. He has worked as a research associate at the University of Maryland, College Park and at Science Applications International Corporation in McLean, VA.

A Cognitive Architecture for
Simulating Bodies and Minds

Professor Sergei Nirenburg
University of Maryland, Baltimore County

1:00-2:15pm Friday, 18 February 2011, ITE 227, UMBC

This talk is an overview of a cognitive architecture that supports the creation and deployment of intelligent agents capable of simulating human-like abilities. The agents, have a simulated mind and may also be supplied with a simulated body. These agents are intended to operate as members of multi-agent teams featuring both artificial and human agents. The agent architecture and its underlying knowledge resources and processors are being developed in a sufficiently generic way to support a variety of applications. In this talk we briefly describe the architecture and two proof-of-concept application systems we have developed within it: the Maryland Virtual Patient (MVP) system for training medical personnel and the CLinician’s ADvisor (CLAD).We organize the discussion around four specific aspects of agent capabilities implemented in MVP and CLAD: physiological simulation, knowledge management and learning, decision-making and language processing.

This is joint work with Marjorie McShane and Stephen Beale, with contributions from Jesse English, Ben Johnson, Bryan Wilkinson and Roberta Catizone.

The UMBC CSEE Department invites applications for a non-tenure track, full-time lecturer position to teach a variety of undergraduate computer science courses.

Charles Croom, of Lockheed Martin will talk about "The State of Cyber Security 2011" at the UMBC Visionaries in IT Forum at 8:00am on Wednesday, February 23rd at the BWI Airport Marriott. The event is free but registration requested.

Croom joined Lockheed Martin Information Systems & Global Solutions as Vice President of Cyber Security Solutions in October of 2008. In this capacity, he shapes the corporation’s cyber security strategy with insight from his 35 years of distinguished service, leadership, and technology experience from the U.S. Air Force. He co-chaired a National Security Telecommunications Advisory Committee Task Force on “Strengthening Government and Private Sector Collaboration” which issued a May 2009 report recommending that the President direct the establishment of a Joint Coordinating Center. He currently serves on the Boards of the National Cyber Security Alliance (NCSA) and the Internet Security Alliance (ISA).

Croom retired as a U.S. Air Force Lieutenant General, Director of the Defense Information Systems Agency (DISA), and the Commander of the Joint Task Force for Global Network Operations in September 2008. While at DISA, he led a worldwide organization of more than 6,600 military and civilian personnel to serve the information technology and telecommunications needs of the President, Secretary of Defense, Joint Chiefs of Staff, combatant commanders, and other Department of Defense stakeholders.

The UMBC Center for Women and Information Technology (CWIT) will hold the second Bits & Bytes event on February 20-21, 2011 for academically talented young women who are juniors in high school and excel in math and science. This year's event is sponsored by Northrop Grumman and is intended to engage local high school girls in the college atmosphere and expose them to the possibilities open to them in Engineering or IT majors in college.

Along with in-depth exposure to life as a college student and UMBC as an institution, the students will participate in an Engineering or IT design competition and will interact with current college students involved in the CWIT Scholars Program, including staying overnight in a residence hall on campus and attending a college class with one of the CWIT students.

GPU Computing: Past, Present, and Future

Dr. David Luebke
Director of Research, NVIDIA Corporation

1:00-2:15pm Friday, 4 February 2011, ITE 227

Modern GPUs have outgrown their graphics heritage in many ways to emerge as the world's most successful parallel computing architecture. The GPUs that consumers buy to play video games provide a level of massively parallel computation in a single chip that was once the preserve of supercomputers. The raw computational horsepower of these chips has expanded their reach well beyond graphics. Today's GPUs not only render video game frames, they also accelerate astrophysics, video transcoding, image processing, protein folding, seismic exploration, computational finance, radioastronomy, heart surgery, self-driving cars – the list goes on and on.

When thinking about the future of GPUs it is important to reflect on the past. How did this peripheral grow into a processing powerhouse found everywhere from medical clinics to radiotelescopes to supercomputers? Why the graphics card and not the modem, or the mouse? Have GPUs really outgrown graphics and will they thus evolve into pure HPC processors? (hint: no)

This talk is intended as a sort of "state of the union" for GPU computing. I'll briefly cover the dual heritage of GPUs, both in terms of supercomputing and the evolution of fixed function graphics pipelines. I'll discuss "computational graphics", the evolution of graphics itself into a general-purpose computational problem, and how that impacts GPU design and GPU computing. Finally I'll describe the important problems and research topics facing GPU computing practitioners and researchers.

David Luebke helped found NVIDIA Research in 2006 after eight years on the faculty of the University of Virginia.
