Karlsruhe Institute of Technology (KIT) scientists will demonstrate several research projects at the upcoming CeBIT conference. In KIT’s language-to-language translation device, automatic language recognition is combined with automatic translation and language synthesis technologies. The system serves as an automatic interpreter of lectures and parliamentary debates. It recognizes and translates language in real time and can be read as a continuously output text or heard over loudspeakers or smartphones. KIT researchers also have developed a system, based on the principle of electromyography, which enables people to speak soundlessly and still to be understood by a conversational partner. Meanwhile, the KIT Institute for Cryptography and Security developed a system that enables mobile users to generate a joint secret that can be used for encoding communications. The system creates a “joint key” for communication partners from the interferences of the radio transmission channel. KIT researchers also have developed Semantic Media Wiki, an extension of the Media Wiki software that enables users to typify cross references within a Wiki.

Information technology (IT) needs to be taught a different way in schools if the industry is to deepen its talent pool, experts in the United Kingdom said during a recent e-Skills event. British Computer Society CEO David Clarke says that although young people are more connected than anyone else in society, they view IT as boring in school because it is taught in a secretarial manner. Students are trained to copy the teachers’ instructions, but they prefer to learn in groups and work on practical tasks, Clarke says. The Confederation of British Industry’s (CBI’s) Lizzie Holman says the same problem exists at the degree level. CBI statistics show that 64 percent of science, high technology, and IT employers believe students do not receive relevant content for the workforce. Europe faces a potential shortage of 384,000 information and communication technology practitioners by 2015, according to the European Commission.

The Obama administration has declassified part of its plan to improve the security of cyberspace in an attempt to cultivate greater collaboration between government and civilian groups. More cooperation between the private sector and the U.S. National Security Agency is the centerpiece of the Comprehensive National Cybersecurity Initiative (CNCI). The declassified abstract of the plan reveals that the U.S. Department of Homeland Security will operate a new security system, called Einstein 3, that analyzes email and other data traffic into and out of federal networks. CNCI also urges merged oversight of federal spending on research and development in cybersecurity, with a particular focus on “leap-ahead” technology. Although the initiative acknowledges that traditional security approaches “have not achieved the level of security needed,” it says the federal government is now outlining “grand challenges” for the research community to help solve the most difficult problems.

Florida State University (FSU) researchers have discovered four crystals that possess properties which could lead to the development of a new generation of computer chips and other information storage devices. “We identified these four crystals as ‘multiferroic,’ meaning that they are simultaneously ferromagnetic and ferroelectric in nature when cooled to a specific temperature,” says FSU professor Naresh Dalal. Multiferroic crystals could be used to create high-powered computer memories that could hold far more information than is currently possible, says FSU professor Sir Harold Kroto. “Theoretically, it might be possible to design devices that are much smaller and faster than the ones we use today to store and transmit data,” Kroto says. The researchers say that electronic devices using multiferroic crystals would have far less environmental impact than devices used today. “The four new multiferroic crystals that we have identified all substitute other, less toxic metals for lead, which is a potent neurotoxin,” Dalal says.

Purdue University researchers have developed a device that uses microring resonators to convert laser pulses into bursts of pulsating radio-frequency signals that avoid interference. The researchers say the technology could eliminate the need for wires when transferring data in homes, offices, and cars. The technology could enable all communications to be transmitted from a single base station, says Purdue professor Minghao Qi. Similar technology could eventually be developed to both transmit and receive signals. The key factor in making the breakthrough practical is that the pulses transmit radio frequencies of up to 60 gigahertz, which does not require a license in the United States. The unlicensed band also is permitted globally, which would allow the system to be implemented worldwide. The system’s tiny silicon microring resonators filter out certain frequencies and allow others to pass. The microring filter can be tuned by heating the rings, which causes them to change and filter out different frequencies.
