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.

Maintaining a Satellite Link: GTRI Agile Aperture Antenna Technology is Tested on an Autonomous Ocean Vehicle

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.

Spear Phishing: Researchers Work to Counter Email Attacks that Gain Recipients’ Trust

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…)
