To get the best care for her three autistic children, Mandi Larkin would drive three hours from her family’s home in Tifton, Ga., to Marcus Autism Center in Atlanta. The drive to and from Atlanta was exhausting. Missed work, missed school and the long drive were constant sources of stress. (more…)
Today’s modeling and simulation (M&S) software provides indispensible tools for systems engineering challenges. Such programs allow investigators to experiment with “what-ifs” by adjusting design parameters and examining potential outcomes.
A team from the Georgia Tech Research Institute (GTRI) has produced an advanced web-based tool that lets physically separated participants collaborate on model-based systems engineering projects. Known as the Framework for Assessing Cost and Technology (FACT), the program utilizes open-source software components to allow users to visualize a system’s potential expense alongside its performance, reliability and other factors.

Antenna technology originally developed to quickly send and receive information through a software-defined military radio may soon be used to transmit ocean data from a wave-powered autonomous surface vehicle. The technology, the lowest-power method for maintaining a satellite uplink, automatically compensates for the movement of the antenna as the boat bobs around on the ocean surface.
The Agile Aperture Antenna technology developed by the Georgia Tech Research Institute (GTRI) is expected to provide a more reliable and faster method of transmitting video, audio and environmental data – such as salinity, temperature, fluorescence and dissolved oxygen – from an ocean vehicle to land via satellite.

The email resembled the organization’s own employee e-newsletter and asked recipients to visit a website to confirm that they wanted to continue receiving the newsletter. Another email carried an attachment that said it contained the marketing plan the recipient had requested at a recent conference. A third email bearing a colleague’s name suggested a useful website to visit.
None of these emails were what they pretended to be. The first directed victims to a website that asked for personal information, including the user’s password. The second included a virus that launched when the “marketing plan” was opened. The third directed users to a website that attempted to install a malicious program. (more…)
A device designed by engineers at the Georgia Tech Research Institute (GTRI) is part of the Hurricane Imaging Radiometer (HIRAD), an experimental airborne system developed by the Earth Science Office at the NASA Marshall Space Flight Center in Alabama.
Known as an analog beam-former, the GTRI device is part of the radiometer, which is being tested by NASA on a Global Hawk unmanned aerial vehicle. The radiometer measures microwave radiation emitted by the sea foam that is produced when high winds blow across ocean waves. By measuring the electromagnetic radiation, scientists can remotely assess surface wind speeds at multiple locations within the hurricanes. (more…)
