Sliding Mode Control (SMC) is a powerful robust nonlinear control technique that has been intensively developed during last 35-40 years. In this talk, the concept of a sliding variable and a sliding surface will be discussed. The Lyapunov’s function-based existence condition for the sliding mode will be presented. The concept of equivalent control and its role in sliding mode control as well as in state- and parameter- observers will be reviewed. The continuous sliding mode control algorithms as well as recently developed higher order sliding mode control will be considered.

The Application of a New Magnetic Resonance Imaging Technique, Tissue Specific Imaging,
to Brain Imaging in Multiple Sclerosis
Magnetic resonance imaging (MRI) is currently the method of choice for anatomical exams in the central nervous system, since it offers excellent soft tissue contrast. However, despite being very sensitive to even small tissue differentiation, it lacks specificity, making it difficult to uniquely associate MRI changes with specific underlying pathology.
The talk will discuss the application of a new anatomical MRI technique, Tissue Specific Imaging (TSI), to brain imaging in Multiple Sclerosis. TSI gives three images, one for each major brain tissue type (gray matter, white matter and cerebrospinal fluid). By combining the information from three images, instead of just one, TSI offers a new way to characterize tissue and lesions. The proposed technique is sensitive to early tissue differentiation, but at the same time is able to distinguish more advanced tissue damage, thus combining sensitivity and specificity in tissue characterization.
Vasiliki N. Ikonomidou received both the diploma in electrical engineering and the Ph.D. in electrical and computer engineering from the Aristotle University of Thessaloniki, Greece. Since 2003 she has been with the National Institute of Neurological Disorders and Stroke, National Institutes of Health (Bethesda), where she is currently a research fellow in the neuroimmunology branch. Her research interests include signal processing, experiment optimization, development and diagnostic applications of magnetic resonance imaging.

Transformers Beyond EPACT 2005 Contribute to Energy and Sustainability Initiatives
EPACT 2005 came into effect on January 1, 2007. It sets NEMA TP1 as national minimum energy efficiency requirements. Legislation was required to prevent the market from continuing to deliver very low efficiency transformers, whose life cycle cost exceeded first cost by a factor of 20 times or more.
However, this minimum requirement falls far short of low lifecycle cost according to extensive Department of Energy analysis. This presentation looks at energy efficiency as an economical source of green power, reviews extensive field data collected on transformer loading, load profile, age, efficiency and power quality. It reviews DOE transformer analysis and proposed efficiency classes, and shows the energy and environmental benefits to moving transformers to low lifecycle cost. Other topics covered include the transformer's impact on energy and power quality, characteristics of a high performance transformer, transformers and LEED, contributions to sustainability initiatives and green purchasing policies, an energy savings and payback calculator, energy monitoring, and protection and control for high performance buildings as well as using building systems as tools to teach sustainability.
Philip Ling, P.E. is vice president of technology at Powersmiths International Corp. He is a LEED Accredited Professional who has been active in the fields of power quality and transformer efficiency for the past 15 years, giving seminars, publishing over two dozen papers and presenting at technical conferences across North America. He sits on the advisory council for the Association for the Advancement of Sustainability in Higher Education, which represents over 150 colleges and universities across the country. In 2000, Philip received a national award for technology leadership in energy efficiency from Natural Resources Canada.

Solid-state Ultra Violet Optical Sources and Their Application Towards Low Cost, Lightweight Biological Agent Detectors
Many devices to detector aerosolized biological agent exploit the fact that fluorophores within the bio-agent particle fluoresce when exposed to ultraviolet light. Historically, these detectors have used UV lasers as the excitation source. Recently, the Defense Advanced Research Project Agency's (DARPA) Semiconductor Ultra Violet Optical Sources (SUVOS) program and others have developed light emitting diodes (LED) based on GaN that are capable of producing output deep into the UV. Compared to lasers, these LEDs are small, low power, and inexpensive. These devices, when incorporated into a detector can lead to a low cost, low power, lightweight bio detection capability. The TAC-BIO program is an attempt to explore the feasibility of using these LEDs within a bio detector and to determine the potential performance bands from such a detector. This talk will describe the TAC-BIO development effort, how these emerging LEDs are being used for this application, key findings, and future development needs in the UV LED area that could have bearing on bio detection programs.
David W. Sickenberger received a B.A. in chemistry from the University of Maryland in 1975. He was worked in both the commercial and government sectors. He has over 30 years experience with the development and testing of C/B detectors. He is currently the team leader for CB System Integration group at the Edgewood Chemical Biological Center where he is developing the next generation of reagentless detectors for aerosolized biological agents. This includes a program to develop a low cost, low power, lightweight biological agent detector based on emerging solid-state ultraviolet sources. The end product has application for both the Department of Defense as well as Department of Homeland Security.

Development of Long Wave Infrared HgCdTe
on Alternate Substrates
HgCdTe is the material of choice for infrared focal plane arrays. Hg1-xCdxTe bandgap varies from -0.3 eV (HgTe) to 1.6 eV (CdTe). Thus Hg1-xCdxTe semiconductor devices cover the infrared spectrum from short wavelength (lambda 1-3 micron) to very long wavelength (lambda > 14 micron). High quality molecular beam epitaxy (MBE) grown Hg1-xCdxTe devices are currently available. However, the producibility of HgCdTe epilayers on alternative substrates and the yield for complex device architectures is still below desired values. The lower than desired yield has been attributed to defects resulting from the growth process and processing induced damage.
Infrared detector performance parameters have been shown to be extremely sensitive to threading dislocation density. This is particularly prominent for long and very long wavelength infrared detectors because of the very narrow band gap and the subsequent sensitivity to defects with energy levels that fall in the mid gap region. The electrical properties of a processed semiconductor depend on the density of surface states and their distribution in energy. Surface depletion or accumulation layers dramatically affect the infrared metallization and passivation processes. In this presentation, current techniques to improve both the growth and processing of HgCdTe infrared detectors will be discussed.
J. David Benson is a research physicist in the science and technology division of the U.S. Army Communications-Electronics Command, Research Development and Engineering Center, Night Vision and Electronics Sensors Directorate at Fort Belvoir, Virginia. Dr. Benson is responsible for the initiation, direction, accomplishment and reporting of applied research involving night vision and electronic sensors technologies, which relate to aviation, land combat, the individual soldier and other mission areas. His primary responsibility is for the lithography and fabrication of HgCdTe and related materials for infrared detectors. He is responsible for the planning and conducting leading edge research in detector fabrication processes for third generation focal plane arrays.
Dr. Benson holds a doctorate in physics from Georgia Tech, where he specialized in solid-state semiconductor physics.
