2009: ECE/WTI Reseach Group Reports on Ad-hoc Mobile Wireless Networks

ECE Prof. and Gilhousen Telecommunications Chair Richard Wolff and other researchers from the MSU ECE and Computer Science departments and the Western Transportation Institute (WTI) recently collaborated on a project with the Hot Springs County (Wyo.) Sheriff’s Department to investigate how Mobile Ad-hoc Networks (MANETs) could be applied to rural public safety. The group's report to the sponsor, the U.S. Department of Homeland Security, demonstrated that in situations with limited conventional network access, a MANET could be effectively used to provide communications at the site of a public safety incident or to extend backbone connectivity over a larger geographic region.

2009: Research Postcard: Cobleigh Hall

Lidar beam and lunar corona

In this photograph taken by Prof. Joe Shaw, a lidar (light detection and ranging) beam is emitted through the roof port in Cobleigh Hall. The lidar is used to detect the properties of tiny dust, smoke, water, and ice particles suspended in the atmosphere high overhead.

The moon in the photograph is surrounded by a corona--a set of colored rings around the moon (or sun) that occurs when light is diffracted by nominally spherical cloud particles. This kind of display almost always is created by tiny liquid water droplets, but can sometimes be caused by unusually small ice crystals.

The lidar data can be used to distinguish between clouds of water droplets and ice crystals based on the properties of the reflected laser pulses.


2009: Research Postcard: Deer Lodge, Montana

Grant-Kohrs Ranch acoustical monitor site

The National Park Service is sponsoring a special acoustics project, directed by ECE Department Head Prof. Rob Maher, to assess and evaluate the baseline soundscape at Grant-Kohrs Ranch National Historic Site, located just north of Deer Lodge, Montana. Grant-Kohrs (GRKO) is a working cattle ranch commemorating the heritage of cowboys, stock growers, and cattle ranchers in the history of the American West during the 19th and 20th centuries.

Montana State University and GRKO staff are implementing a year-long acoustical study of the natural, cultural, and community sounds that comprise the ambient acoustic environment of the historic site.

The audio measurements will establish an acoustic "baseline" to help park managers understand the seasonal variation in sounds at the ranch due to wildlife, livestock, ranch operations, and ranch visitors. The audio measurements will also help assess the level of noise attributable to external sound sources in the vicinity of the historic site, such as highway traffic, aircraft, and recreational activities, and the potential impact of community growth on the acoustical integrity of the visitors' experience. One of the results will be a 365 day long MP3 recording of the site: that will be 8,760 hours of audio! More information: GRKO Sound Project.

2008: NASA Awards Research Grant for High Spectral Resolution Lidar

The National Aeronautics and Space Administration (NASA) has awarded a new grant to a team consisting of MSU ECE Professors Kevin Repasky (PI) and Joe Shaw (Co-PI), MSU Physics Prof. John Carlsten (Co-PI), and Visiting Professor John Reagan (Co-PI) of the University of Arizona. The project is entitled Development of a Novel High Spectral Resolution Lidar for Studies of the Effects of Aerosols on the Earth's Climate System, and is funded under the NASA Experimental Program to Stimulate Competitive Research (EPSCoR) program administered by NASA Headquarters in Washington, DC.

The research project involves the design, construction, and evaluation of a High Spectral Resolution Lidar system for measuring aerosols in the Earth's atmosphere. Lidar, an acronym for light detection and ranging, is a technique that shines a specially formulated laser beam into the atmosphere overhead and detects the properties of the light that bounces back at different altitudes from suspended particles in the air. This remote-sensing technique allows the researchers to learn more about the properties and characteristics of the atmosphere, and ultimately how the atmospheric composition affects global climate.

The EPSCoR award provides $750,000 for a three-year period beginning 9/1/08. The MSU team will work closely with researchers from the NASA Langley Reseach Center in Virginia, including Dr. Christopher Hostetler, Dr. Jonathan Hair, and MSU alumnus Dr. Michael Obland. Four MSU graduate students and two undergraduate students will also be supported by the project.

2008: Research Postcard: Mauna Loa Observatory, Hawaii

optics research in Hawaii

Aloha, Montana! ECE doctoral student Andrew Dahlberg, Prof. Joe Shaw (PI), and post-doc Nathan Pustare pictured with their tripod-mounted all-sky polarization imaging system located 11,135' (3,394m) above sea level at the Mauna Loa Observatory (MLO) on the island of Hawaii. Prof. Shaw's project is sponsored by the Air Force Office of Scientific Research.

The detection system acquires images of the sky polarization, which depends strongly on aerosol content. The term aerosol refers to the presence of tiny solid and liquid particles suspended in the air, such as dust, smoke, and chemical compounds. The MLO is a desirable location to conduct optical calibration experiments because of the very low aerosol content in the atmosphere over Hawaii.

The polarization imaging experiments run from mid-May through June 5, 2008.
