CU-Boulder, USCS to lead E-vehicle studies
Oct 17th
COLORADO SPRINGS, Colo. – University of Colorado Boulder faculty will join with University of Colorado Colorado Springs faculty to teach courses in the design and implementation of electric vehicle drivetrains to new and retraining engineers.
The U.S. Department of Energy recently provided a five-year $954,000 grant to UCCS for the development of courses to prepare engineers for careers in developing new technologies for vehicles having electric drivetrains. The master’s-level courses will be taught by both UCCS and CU Boulder faculty members with expertise in batteries, battery controls, and power electronics.
The courses will be available through distance learning technologies such as online courses and, possibly, CISCO Telepresence, in addition to traditional in-person classrooms, making them available to people nationwide.
“There are thousands of engineers who have either been displaced as the U.S. auto industry shifted or who have an interest in learning about creating vehicles of the future,” Greg Plett, professor, UCCS College of Engineering and Applied Science, said. “This program offers them the opportunity to retrain without relocating.”
Plett, the principal investigator on the project, has spent his career working with battery controls and has close relationships to many Colorado-based companies who manufacture batteries or their controls as well as large corporations such as General Motors. Plett is working with General Motors’ engineers on new methods for battery controls in future extended range electric vehicles, beyond the Chevy Volt.
The GATE Center of Excellence in Innovative Drivetrains in Electric Automotive Technology Education will provide students the opportunity to earn a graduate certificate in electric drivetrain technology by taking four courses in battery dynamics, battery controls, power electronics and detailed courses in adjustable alternating current drives. Plans also call for creating options for students in master’s of science in electrical engineering programs at UCCS and CU-Boulder to pursue specialization in fields such as battery controls, taught by UCCS faculty, and vehicle power electronics taught by CU-Boulder faculty members.
CU-Boulder faculty will build upon strengths of the Colorado Power Electronics Center research and education programs, including a highly successful Professional Certification in Power Electronics already offered online by the College of Engineering and Applied Science’s distance education program (http://cuengineeringonline.colorado.edu/)
“This program combines the strengths of the faculty of two CU campuses for the benefit of students,” Plett said.
Plett also believes the collaboration of faculty will lead to new research in battery technology. Battery life and power outputs have long been considered hindrances to the development of electric vehicles including cars, trucks and mass transit vehicles.
Plett envisions that fellowships to reduce the cost of the graduate coursework will be available with 30 to 40 students enrolled annually beginning with the fall 2012 semester.
Working with Plett will be Scott Trimboli, assistant professor, UCCS College of Engineering, and Regan Zane, associate professor, Department of Electrical, Computer, and Energy Engineering, CU-Boulder, and Dragan Maksimovic, professor, Department of Electrical, Computer, and Energy Engineering, CU-Boulder.

CU-Boulder student treated for meningitis
Oct 17th
A 21-year-old female student at the University of Colorado Boulder was diagnosed late on Friday with meningococcal meningitis according to county and university health officials. The student, who is a junior living off campus, is in stable condition at Boulder Community Hospital.
Boulder County Public Health officials are investigating the single case. No other cases of the disease have been confirmed by county or state officials at present.
Meningococcal meningitis is a serious bacterial infection that causes infection of the tissue surrounding the brain and spinal cord. Meningococcal disease may be spread to others; however, this is uncommon.
“Most of those CU community members who have had close contact with this student have already been contacted and offered treatment by Boulder County Public Health,” said Dr. Don Misch, CU-Boulder assistant vice chancellor for health and wellness.
The risk to other people is minimal and is confined to those who have had close contact with the patient. Close contact includes kissing; sharing cigarettes, drinks, glasses or eating utensils; and being exposed to secretions from the nose or throat of the infected person.
“Others, particularly undergraduate students who have never been vaccinated for meningococcal meningitis or have not been vaccinated in the past five years, should consider getting the vaccination,” Misch said. “On a university campus, those at greatest risk in general for meningococcal meningitis are students living in residence halls, so these individuals should especially consider vaccination at Wardenburg Health Center or from their personal health care provider.”
“Vaccination is the most effective way to protect against this severe disease,” said Murielle Romine, Boulder County Public Health communicable disease control program coordinator.
Symptoms of meningococcal meningitis can include fever, severe headache, stiff neck, irritability, sleepiness, nausea, vomiting, rash, disorientation and confusion. A person may be infected for one to 10 days, and most commonly three to four days, before showing any symptoms.
The last reported case of meningococcal meningitis at CU-Boulder was in March 2006. That student, a male, recovered fully.
Those who are interested in getting the vaccination can go to Wardenburg Health Center from 8:30 to 11 a.m. and from 1:30 to 4 p.m. Monday through Friday.
Wardenburg Health Center is open Monday through Thursday from 8 a.m. to 6 p.m., Friday from 8 a.m. to 5 p.m., and Saturday from 9 a.m. to 2 p.m.
Parents of all incoming freshmen receive a letter during the summer with information about the recommendation for immunization.

CU-BOULDER SPACE SCIENTISTS READY FOR ORBITAL INSERTION OF MERCURY SPACECRAFT
Mar 15th
March 15, 2011
NASA’s MESSENGER mission, launched in 2004, is slated to slide into Mercury’s orbit March 17 after a harrowing 4.7 billion mile journey that involved 15 loops around the sun and will bring relief and renewed excitement to the University of Colorado Boulder team that designed and a built an $8.7 million instrument onboard.
“In 2004, this milestone seemed like it was a long, long way away,” said Senior Research Associate William McClintock, a mission co-investigator from CU-Boulder’s Laboratory for Atmospheric and Space Physics. “But here we are at last, poised to help solve some of the many tantalizing mysteries about Mercury.”
The smallest of the solar system’s four rocky planets, Mercury is about two-thirds of the way nearer to the sun than Earth and has been visited by only one other spacecraft, NASA’s Mariner 10, in 1974 and 1975. CU-Boulder scientists say learning what makes the hot, rocky planet tick will help them better understand the formation and evolution of planetary systems.
The refrigerator-sized spacecraft is carrying seven instruments — a camera, a magnetometer, an altimeter and four spectrometers. Designed and built by CU-Boulder’s LASP, the Mercury Atmospheric and Surface Composition Spectrometer, or MASCS, is a power-packed, 7-pound instrument that will make measurements of Mercury’s surface and its tenuous atmosphere, called the exosphere.
MASCS breaks up light like a prism, and since each element and compound has a unique spectral signature, scientists can determine the distribution and abundance of various minerals and gases on the planet’s surface and exosphere, said McClintock. “We now know Mercury’s exosphere is constantly changing,” he said.
During a 2009 MESSENGER flyby of Mercury, MASCS detected magnesium, an element created inside exploding stars, clumped in the exosphere. The team determined magnesium, sodium and potassium and several other kinds of atoms flying off Mercury’s surface were being accelerated by solar radiation pressure to form a gigantic tail of material flowing away from the sun, said McClintock.
“All of the instruments on MESSENGER had to be extremely light, which stretched our imaginations and creativity,” Lankton said. “We have learned a lot, and wound up getting a lot of bang for our buck.”
LASP Director Daniel Baker, also a co-investigator on the MESSENGER mission, is studying Mercury’s magnetic field and its interaction with the solar wind, including violent “sub-storms” that occur in the planet’s vicinity. Since Mercury is the closest planet to the sun, MESSENGER is equipped with a large sunshade and heat-resistant ceramic fabric to protect it, said Baker.
“The three successful flybys of MESSENGER past Mercury have already rewritten the textbooks about the sun’s nearest neighbor,” Baker said. “We are pleased by all we have learned about the space environment of the planet. But we think there is so much more to learn — we’ve probably just scratched the surface, so to speak.”
Baker said the orbit insertion of Mercury will be celebrated by all of LASP, including a solar science team that saw its $28 million instrument crash into the sea March 4 due to problems with a NASA-contracted launch vehicle. “A very important aspect of LASP is that it is like a big family,” Baker said. “Everyone shares the joys of success and the sorrow of failure, which has been a blessedly rare occurrence in our history.”
“We have all of our appendages crossed for a successful orbit insertion,” said LASP’s Mark Lankton, program manager for MASCS. “MESSENGER is part of NASA’s Discovery Program, and I’d be surprised if we don’t continue to be surprised. Once we are in Mercury’s orbit we are going to be getting a bounty of new data every day.”
Dozens of undergraduates and graduate students will be involved in analyzing data as information and images begin pouring back to Earth from MESSENGER, dubbed “the little spacecraft that could” by LASP scientists. “This mission is going to be a field day for students, not only at CU-Boulder, but for students all over the world,” said Baker.
CU-Boulder’s LASP is the only space institute in the world to have designed and flown instruments that have visited or are en route to every planet in the solar system. LASP also has a student-built dust-counting instrument on NASA’s New Horizons Mission, launched in 2006 to Pluto and now approaching the orbit of Uranus.
“LASP has some of the best people in the world pursuing great science, great engineering, wonderful mission operations, and superb administrative and managerial achievement,” said Baker. “When such a team is given the facilities and resources to thrive, the sky is the limit. But it all starts with our people, including our students.”
The data will be sent via NASA’s Deep Space Network to the Applied Physics Laboratory at Johns Hopkins University — which is managing the mission for NASA — where mission scientists, including researchers and students at LASP’s Space Technology Building at the CU Research Park, will access it electronically, he said.
Sean Solomon from the Carnegie Institute of Washington in Washington, D.C., is the chief MESSENGER scientist.

Located at 1234 Innovation Drive on CU-Boulder’s East Campus, LASP is hosting an open house March 17 to celebrate the MESSENGER spacecraft’s insertion into orbit around Mercury. Doors will open at 5:30 p.m. Lankton will give a talk on the mission and Clark Chapman of the Southwest Research Institute in Boulder will give a talk on Mercury beginning at 6 p.m. NASA’s broadcast of the orbit insertion — a 15-minute maneuver — will take place beginning at 6:45 p.m.
