    www.bigbandjazzfest.org The Calvin Jones BIG BAND Jazz Festival celebrates 29 years of world-class jazz at the University of the District of Columbia. The Big Band sound returns to UDC as the powerhouse jazz ensembles from the University of the District of Columbia (directed by Allyn Johnson), Howard University (directed by Fred Irby III) and the University of Maryland (directed by Chris Vadala) once again cap off Jazz Appreciation Month with a with a hand-clapping, finger-snapping, foot-stomping good time. Produced by UDC's Jazz Studies Program and the Felix E. Grant Jazz Archives, the festival began in 1987 as part of a citywide tribute to Duke Ellington, and it remains one of the most anticipated events on Washington, DC's jazz calendar. Scholarship Benefit Series. University Auditorium — Theatre of the Arts (Bldg. 46-East). Tickets are $20 (general admission), $15 (seniors), and $10 (students) and can be purchased in advance at the UDC Music Program, Building 46-West or online at InstantSeats.com.

      • Quartz MEMS: Only a Matter of Time!

        Srinivas Tadigadapa The Pennsylvania State University Abstract The extraordinary stability of quartz resonators and accuracy of around 30 ms per year has made them the most ubiquitous time sensors. Micromachining quartz offers various new configurations and advantages for gravimetric, thermal, viscoelastic, and magnetic sensing. Specifically, this talk will demonstrate the applications of micromachined bulk acoustic wave resonators for the systematic investigation of adsorbing films and nanomaterials on their surface. The response of the resonators to various surface loads has been carefully modeled assuming a dynamically forming viscoelastic film under a fluidic overlayer. Micromachined shear wave resonators, have been investigated for their response to organized ferrofluids atop the resonator electrodes. This configuration was capable of achieving magnetic field sensitivities in the nanoTesla range in addition to providing insight into the process of ordered assembly of ferrofluid particles at the interface. Finally the talk will demonstrate thermal sensing capabilities of micromachined quartz resonators. As we will see, no matter the configuration of the sensing application, quartz MEMS are only a matter of time! Biography Srinivas Tadigadapa, is a Professor of Electrical Engineering and Bioengineering at the Pennsylvania State University. He obtained his Ph.D. from Cambridge University, UK in 1994. 1996-2000 he was Vice President of Manufacturing at Integrated Sensing Systems Inc., Michigan and was involved with the design, fabrication, packaging, reliability, and manufacturing of micromachined Coriolis mass flow sensors and pressure sensors. His current research interests include integrated heterogeneous materials based microsystems, bio and chemical sensors, and exploring electric and thermal transport at the micro-nano interfaces. He has been a research fellow at the University of Karlsruhe, Germany and a Visiting Professor at Otto von Guericke University, Magdeburg, Germany, and University College, Cork, Ireland. He has been the recipient of the Alexander von Humboldt fellowship in Germany and the Walton Fellowship by the Science Foundation of Ireland. He is a life fellow of the Cambridge Philosophical Society, Fellow of the Institute of Physics, London, Senior Member of IEEE, and currently serves as an associate editor of the Journals: Measurement Science and Technology and SPIE Journal of Microlithography, MEMS, and MOEMS.

              Robotics @ Maryland's ( http://ram.umd.edu ) Autonomous Underwater Vehicle (AUV) Tortuga 2 successfully drops markers in two cards of the black jack table. This is in the Space Systems Lab's ( http://ssl.umd.edu ) Neutral Buoyancy Research facility. Tortuga 2 is maneuvering between the "cards" of the "black jack table", an objective of this years AUVSI International AUV Competition ( http://auvsi.org/competitions/water.cfm ). It sequentially checks each card and drops a flashing marker in the club (at time 1:07) and diamond (at time 2:28) bins. The robot is under complete autonomous control. The flashing markers are capacitor powered and can be recharged. This work was made possible by the hard work of the vision and AI teams over hours of testing and tuning.

                Robotics @ Maryland's ( http://ram.umd.edu ) Autonomous Underwater Vehicle (AUV) Tortuga follows two sections of an orange pipeline. This is in the Space Systems Lab's ( http://ssl.umd.edu ) Neutral Buoyancy Research facility. This is the height of over a year of work by 20 students at the University of Maryland ( http://www.umd.edu ). At last years 2007 AUVSI International AUV Competition ( http://auvsi.org/competitions/water.cfm ) about 1/5 of the years teams were able to follow any sections of the orange pipe. Only three were able to follow multiple sections as Tortuga has done in the video above. This work was made possible by the hard work of vision team, and our recent addition an additional two thrusters which allows for sideways motion.

                  Robotics @ Maryland's ( http://ram.umd.edu ) Autonomous Underwater Vehicle (AUV) Tortuga seeks and hits a red light underwater. This is in the Space Systems Lab's ( http://ssl.umd.edu ) Neutral Buoyancy Research facility. This video is running at several times normal speed and is from the vehicle's forward camera. This is height of over a year of work by 20 students at the University of Maryland ( http://www.umd.edu ). Only a 1/4 of last years teams were able to hit the red light at the the 2007 AUVSI International AUV Competition ( http://auvsi.org/competitions/water.cfm ).
