Study of April 27, 2011, tornadoes affirms theories about the causes

KKnuppAMSFellowTN

The atmosphere in the southeastern U.S. was primed for disaster in late April 2011. Conditions were almost perfect for a massive outbreak of tornado spawning storm cells.

Over a four-day period - April 25 through April 28 - at least 356 tornadoes were spun out of a series of atmospheric disturbances that affected an area from northeastern Texas to New York; 199 of those tornadoes, including the deadliest and most powerful, hit Alabama and surrounding states on April 27, 2011, killing 361 people, leaving another 2,700 injured and causing an estimated $4 billion in damage.

UAH president tours new Army manned/unmanned systems lab

MA4A9753Small

UAH President Robert Altenkirch toured a new Manned/Unmanned Collaborative Systems Integration Laboratory in Olin B. King Technology Hall on campus on Tuesday, Oct. 1.

The culmination of efforts that began in 2009, the $80,000 lab is a UAH/Army partnership and was built for the cost of materials alone by the America's Army Game Studios, said Dr. Thomas W. Davis, chief of the weapons branch of the U.S. Army's Research, Development and Engineering Command (RDECOM) at the U.S. Army Research Laboratory. The new lab will utilize data collected from UAH student players, who have grown up with video games, to develop warfighter systems to build effective teaming, decision making and performance, said Dr. Davis.

6th Wernher von Braun Memorial Symposium coming

VBtn

The sixth Wernher von Braun Memorial Symposium will be held by the American Astronautical Society (AAS) Oct. 7-10 in Chan Auditorium of the Business Administration Building on the campus of UAH.

"The symposium is an excellent way to draw together experts in the field, who then have the opportunity to exchange information and together envision the future of space exploration," said Dr. Ray Vaughn, UAH vice president for research. "It's a great way for the leaders in their fields to communicate with each other, touch base on developments and plan what's next."

Lasers key to UAH team’s asteroid defense system

IMG 9270ThNail

A space-based laser system proposed to NASA by UAH researchers could be a cost-effective way to nudge small asteroids away from a collision course with Earth.

With the February meteor explosion in Russia heightening U.S. government interest in how asteroid collisions with Earth can be prevented, the UAH scientists say using their system against smaller asteroids will provide practical scientific data needed to scale it up to defend against very large asteroids.

UAH student invited to be guest lecturer at Space-X

Aero Space_EngineeringTN

The same type of white noise you hear from a TV set, properly applied, could prevent a rocketry catastrophe.

That's attracted the interest of Space-X to a UAH graduate student's innovative new approach to suppressing combustion instabilities in rocket engines.

John Bennewitz, a Von Braun Propulsion Scholar at the UAH Propulsion Research Center who is working with advisor Dr. Robert Frederick, will be a visiting lecturer at Space-X's facility in Hawthorne, Calif., on Friday, Sept. 27, where he will tell employees of the firm that designs, manufactures and launches advanced rockets and spacecraft about his efforts in applying band-limited white noise to neutralize combustion instabilities.

UAH students to present at astronautical conference in Beijing

beijingTN

Presenting your research at a major conference is intimidating for anyone, let alone a student who is just starting out in their academic career. Now imagine doing it in a foreign country in front of the biggest names in your field.

But that's exactly what six students from The University of Alabama in Huntsville (UAH) will be doing later this month, when they attend the 2013 International Astronautical Congress (IAC) in Beijing, China, from Sept. 23 to 27.

Community-involved retailers profit from it, study says

Tim Landry_3TN

Getting immersed in the community and fostering a community atmosphere among customers aids a retailer's bottom line, whether the business is small and locally owned or a large global chain, according to research co-authored by a UAH associate professor of marketing.

The lead article in the summer issue of the Journal of Marketing Theory and Practice demonstrates how retailers benefit from employment of four social functions associated with development of community - socialization, mutual support, social participation and social control. ("The Development of Core Retailer Community Functions"; Todd J. Arnold, Elten Briggs, Timothy D. Landry, Tracy Suter; Journal of Marketing Theory and Practice, Vol. 21, No. 3, Summer 2013) And fostering community is a huge chunk of the retail equation.

UAH's miniature satellite, ChargerSat-1, receives send-off before space launch

chargersatframeTN

Members of the Huntsville space exploration community were invited to a Bon Voyage reception for the ChargerSat-1 yesterday. Designed and constructed by the Space Hardware Club (SHC), a student-run organization at UAH, the miniature satellite will be launched into space on November 4.

SHC member Mark Becnel, who will graduate from UAH this December with a master's degree in Aerospace Engineering, delivered a few words about the satellite, its history, and its upcoming trip to the gathered audience.

UAH device gives scientists front-row seat to lightning strikes

Bitzer TN2

A device developed at UAH has become a valuable tool in researchers' quest to determine how lightning is spawned in clouds, to map strikes from beginning to end and to better predict severe weather.

The Huntsville Alabama Marx Meter Array (HAMMA) sensor literally resides under a large inverted metal salad bowl to protect the electronics from rain. A modern electronic reinvention of a sensor first developed in the 1950s, it detects the radiated electric field in the atmosphere when lightning strikes.
