Based only on its appearance in imagery, this program uses close-range 3D terrain analysis to produce training data sufficient to estimate the traversability of terrain beyond 3D sensing range. This approach is called learning from stereo (LFS). In effect, the software...

An algorithm was developed to generate crop yield predictions from orbital remote sensing observations, by analyzing thousands of pixels per county and the associated historical crop yield data for those counties. The algorithm determines which pixels...

AEGSE Virtuoso Charting is an application that enables animated, real-time charting of telemetry streams of data from a rover. These automatically scaled charts are completely interactive, and allow users to choose the variables that they want to monitor. The charts can process...

A voice-command human-machine interface system has been developed for spacesuit extravehicular activity (EVA) missions. A multichannel acoustic signal processing method has been created for distant speech acquisition in noisy and reverberant environments....

Weather forecasting, hurricane tracking, and atmospheric science applications depend on humidity sounding of atmosphere. Current instruments provide these measurements from ground-based, airborne, and low Earth orbit (LEO) satellites by measuring radiometric temperature on the flanks of the 183-GHz water...

A differential SiGe oscillator circuit uses a resonant ring-oscillator topology in order to electronically tune the oscillator over multi-octave bandwidths. The oscillator’s tuning is extremely linear, because the oscillator’s frequency depends on the magnetic tuning of a YIG sphere, whose...

Yesterday, after unveiling Creo, PTC's soon-to-arrive design application suite, the company arranged for a panel of analysts to address attendee questions about the product. The roundtable included Marc Halpern, Research VP at Gartner, Sanjeev Pal, Research Manager at IDC, and John MacKrell, a senior consultant at...

There was a bit of a crowd lining up near Boston's Park Plaza this morning, and if it wasn't for all the business-casual attire, you may have thought another Apple Store was opening up down the street. The event was actually PTC's unveiling of its new product suite: Creo. Here's the quick rundown: Creo is a suite...

This week's Question of the Week addresses another technical development from Google. In early October, the search giant announced that it has been testing robotic cars on U.S. city streets. The vehicles, equipped with a complex array of sensors and cameras that allowed them to steer around...

This week's Question of the Week addresses home foreclosures. Several major home lenders, including JP Morgan Chase and Bank of America, have suspended foreclosures in parts or all of the country because of sloppy paperwork and improper oversight of the many loans that went bad. Some say, absent...

This week's Question of the Week addresses Google TV. Engineers are putting the finishing touches on Google TV, a software platform that aims to bring the complete Internet experience to television sets. Expected in stores later this month, the Google TV device has a remote-control keyboard/pointing device...

This week's Question of the Week concerns a recent Gallup poll that revealed that a majority of Americans (57%) say they have little or no trust in the mass media to report the news fully, accurately, and fairly. Sixty-three percent of respondents perceived bias. What do...
