Researchers at Penn State developed a new marking scheme that can identify the originator of spam, viruses, and illegal file-sharing messages with high accuracy. The approach uses border routers to mark packets with identifying numbers, allowing for efficient traceback of malicious content.
The US Army has awarded UCSD a five-year grant to develop innovative wireless networking technology for tactical environments. The project aims to create cross-layer algorithms and new antenna technologies to enhance network adaptability and resilience in the face of enemy jamming and eavesdropping attempts.
Researchers from Penn State have developed an approach that improves existing local area networks and shows copper wire is a competitive option for new installations. The scheme jointly codes and decodes signals, eliminating crosstalk and achieving high bit error rates.
Researchers at Penn State have developed a new type of sensor that can detect hydrogen levels with incredible sensitivity. The titania nanotube sensors are 200 times more sensitive than previously used materials and offer several advantages, including high response rates and minimal interference from other gases.
Researchers Jody O'Sullivan and Pierre Moulin have developed a theory that sets fundamental limits on the amount of information that can be reliably hidden in various data types. This breakthrough has significant implications for security applications, including detecting forgery and intercepting terrorist messages.
Researchers have captured an unusual sprite-like blue jet over Puerto Rico, exhibiting characteristics of both blue jets and sprites. The event's unique features include a branching conical shape and hot spots, which are similar to those seen in computer models but not fully explained.
A new book series, interCONNECTIONS, aims to capture the attention of girls ages 8-11 and maintain their interest in math and science. The series features interactive, modular toys/boardgames that bring intangible concepts to life through metaphors and physical connections.
Only about a third of engineering schools in the US require all students to take an ethics course, according to UMass professor Karl Stephan. This lack of emphasis on ethics raises concerns about the impact of technology on society and the need for engineers to consider the ethical implications of their work.
Two Stanford University scientists argue that large amounts of water ice are unlikely on the Moon, suggesting an alternative explanation involving the reaction of lunar dust with hydrogen and oxygen. They propose that the Lunar Prospector crash could produce a plume of water vapor and hydroxyl ions without ice being present.
Kansas State University has expanded its Experimental Engineering Model with an $800,000 NSF grant, providing college-level engineering students with real-world experience and skills in a manufacturing environment. The program aims to equip graduates with industry-relevant traits, such as communication and teamwork.
Researchers are developing a non-destructive testing technique that can detect cracks in materials and welds under extreme conditions. This technology is being adapted for use in space to test the International Space Station and other structures, reducing the need for costly repairs.
Researchers at Virginia Tech are developing a low-power, high-data-rate wireless communications device that uses a new type of computer-based radio. The Changeable Advanced Radio for Inter-Operable Telecommunications (CHARIOT) will automatically adapt to different standards, enabling seamless communication.
