NASA Model Provides 3-D View of L.A. Earthquake

On March 28, residents of Greater Los Angeles experienced the largest earthquake to strike the region since 2008. The magnitude 5.1 quake was centered near La Habra in northwestern Orange County about 21 miles (33 kilometers) east-southeast of Los Angeles, and was widely felt throughout Southern California. There have been hundreds of aftershocks, including one of magnitude 4.1.Scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif., have developed a model of the earthquake, based on the distribution of aftershocks and other seismic information from the U.S. Geological Survey.A new image based on the model shows what the earthquake may look like through the eyes of an interferometric synthetic aperture radar, such as NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR). JPL scientists plan to acquire UAVSAR data from the region of the March 28 quake, possibly as soon as this week, and process the data to validate and improve the results of their model. The UAVSAR flights serve as a baseline for pre-earthquake activity. As earthquakes occur during the course of this project, the team is measuring the deformation at the time of the earthquakes to determine the distribution of slip on the faults, and then monitoring longer-term motions after the earthquakes to learn more about fault zone properties.

Engineers Design Software Tools to Secure Tactical Smartphones

Suraj Kothari's talk of smartphone security quickly took a turn toward sabotage and worst-case scenarios. What happens, he asked, if a soldier's smartphone is hacked for its GPS data? What happens if an attacker drains the battery in a general's phone and essential communication is cut off? Or, what happens if a hacked phone provides false information during a military mission?

Air And Missile Defense System To Get Smarter Software

When a missile is launched against an enemy target, it would be nice to have a lot of good information about that target. But when "decision makers push the fire button, they may have very little data, and sometimes not timely enough data," said Col. Rob Rasch Jr., project manager, Integrated Air and Missile Defense Project Office, or IAMD, at Redstone Arsenal, Ala. "Nowhere in the current Army architecture is there a way to share information from all of our various sensors and weapons to have better integrated coverage," he pointed out, referring to situational awareness for those operating Patriot and other missile defense systems like those used for short-range air defense.

Driving Simulator Helps Engineers Calculate Human Factor

Simulations are an important development tool in the automobile and utility vehicle. The properties of vehicle components, such as how they respond in an accident, their reliability, or their energy efficiency can be investigated using simulations before the first component is manufactured. Researchers developed an interactive driving simulator using RODOS (robot-based driving and operation simulator) with which realistic interaction between human and vehicle can be analyzed.

What They Didn’t Teach You in Engineering School About Heat Transfer

Until recently, the commercial software available for CFD typically has been geared towards specialists, limiting its widespread use. Besides being expensive, these tools have either been difficult, cumbersome or time-consuming to use. As a result, engineering analysis for applications such as heat transfer traditionally have been carried out by specialists in analysis departments, separate from mainstream design and development departments.
