PASADENA, Calif. – The space-based technology that lets GPS-equipped motorists constantly update their precise location will undergo a major test of its ability to rapidly pinpoint the location and magnitude of strong earthquakes across the western United States. Results from the new Real-time Earthquake Analysis for Disaster (READI) Mitigation Network soon could be used to assist prompt disaster response and more accurate tsunami warnings.

The new research network builds on decades of technology development supported by the National Science Foundation, the Department of Defense, NASA and the U.S. Geological Survey (USGS). The network uses real-time GPS measurements from nearly 500 stations throughout California, Oregon and Washington. When a large earthquake is detected, GPS data are used to automatically calculate its vital characteristics, including location, magnitude and details about the fault rupture. (more…)

Space Weather Forecast: Sunspotty, With an Increasing Chance of Solar Storms

The past few months have seen a spate of solar flares – bringing spectacular views of the northern lights as far south as Seattle – along with media speculation that the electrical activity could disrupt power grids, satellites or ground airplanes.

John Sahr, a UW professor of electrical engineering who studies the upper atmosphere, is the regional go-to guy for such questions. We found some time in Sahr’s busy schedule (he’s also the UW’s associate dean of undergraduate academic affairs and a part-time zombie hunter) to get his read on the space weather forecast. (more…)

AUSTIN, Texas — A systematic analysis of power usage in microprocessors could help lower the energy consumption of both small cellphones and giant data centers, report computer science professors from The University of Texas at Austin and the Australian National University.

Their results may point the way to how companies such as Google, Apple, Intel and Microsoft can make software and hardware that will lower the energy costs of very small and very large devices. (more…)

*IBM completes acquisition of Emptoris to expand Smarter Commerce initiative*

ARMONK, N.Y., – 01 Feb 2012: IBM today announced it has completed its acquisition of Emptoris Inc. The acquisition expands IBM’s cloud-based analytics offerings that provide supply chain intelligence leading to better inventory management and cost efficiencies.

Emptoris solutions bring more intelligence to procurement and supply chain operations with spend, supplier and contract management for Smarter Commerce. Smarter Commerce helps organizations that are struggling to meet the demands of a rapidly changing market. The acceleration in online connectivity and speed, combined with the explosion of information and unprecedented access to it, is reshaping globally interconnected commerce systems. This new digital marketplace requires companies to respond rapidly to customer demands by automating their buying, marketing, selling and service processes. (more…)

Some Dating Websites Do Not Remove GPS Data From Photos, CU-Boulder Students Find

While the majority of dating websites do a good job of managing the privacy of their users, a class research project at the University of Colorado Boulder’s Leeds School of Business found that 21 of 90 dating websites the class examined did not properly remove location data from pictures uploaded by their users.

As a result of people taking more photographs with cameras and cell phones containing Global Positioning System chips, some dating website profile pictures contain GPS coordinates showing where a picture was taken, said Associate Professor Kai Larsen, who taught the class on Privacy in the Age of Facebook. When such information is not removed by the dating website, commonly available tools can be used to detect the location of a person’s residence or other locations frequented by the user. (more…)

Some Earthquakes Expected Along Rio Grande Rift in Colorado And New Mexico, New Study Says

The Rio Grande Rift, a thinning and stretching of Earth’s surface that extends from Colorado’s central Rocky Mountains to Mexico, is not dead but geologically alive and active, according to a new study involving scientists from the University of Colorado Boulder’s Cooperative Institute for Research in Environmental Sciences.

“We don’t expect to see a lot of earthquakes, or big ones, but we will have some earthquakes,” said CU-Boulder geological sciences Professor Anne Sheehan, also a fellow at CIRES. The study also involved collaborators from the University of New Mexico, New Mexico Tech, Utah State University and the Boulder-headquartered UNAVCO. The Rio Grande Rift follows the path of the Rio Grande River from central Colorado roughly to El Paso before turning southeast toward the Gulf of Mexico. (more…)

MU Engineers Developing Military Applications for Smartphones

COLUMBIA, Mo. – Tracking military targets? The University of Missouri’s College of Engineering has an app for that.

Engineers from the MU College of Engineering, with funding from the U.S. Army/Leonard Wood Institute, have enhanced popular smartphones to be able to find and track targets. In addition, the engineers have developed ad hoc networks so that soldiers can relay smartphone information without using the internet. (more…)

*Ecological changes from lakebed may have led to two different populations of once-related steelhead trout*

A catastrophic landslide 22,500 years ago dammed the upper reaches of northern California’s Eel River, forming a 30-mile-long lake which has since disappeared. It left a living legacy found today in the genes of the region’s steelhead trout.

Using remote-sensing technology known as airborne Light Detection and Ranging (LiDAR) and hand-held global-positioning-systems (GPS) units, scientists recently found evidence for a late Pleistocene, landslide-dammed lake along the river. (more…)
