A set of techniques used in image processing that allow better viewing between the lighter and darker areas of an image. A study by Raquel Gil Rodríguez, Javier Vázquez-Corral and Marcelo Bertalmío, researchers of the Image Processing for Enhanced Cinematography (IP4EC) research group.

A new uncrackable security system created by researchers at King Abdullah University of Science and Technology (KAUST), the University of St Andrews and the Center for Unconventional Processes of Sciences (CUP Sciences) is set to revolutionize communications privacy.

Researchers working on an Army-funded project have developed an algorithm to simulate how electromagnetic waves interact with materials in devices to create equipment more efficiently and accurately. The algorithm could be used in a wide range of fields -- from biology and astronomy to military applications and telecommunications.

Thanks to the implementation of advanced random access schemes using efficient, low complexity algorithms. According to a study published in International Journal of Satellite Communications and Networking of which one of its authors is Giuseppe Cocco, a researcher at the DTIC and at the German Aerospace Center (DLR).

Scientists have for the first time shown that it is possible to detect the propagation of seismic waves on the seafloor using submarine telecommunications cables. According to their observations, this existing infrastructure could be used to detect earthquakes, as well as swell and underwater noise.

A University of Illinois-based team of engineers has found that the model currently used to predict heat loss in a common semiconductor material does not apply in all situations. By testing the thermal properties of gallium nitride semiconductors fabricated using four popular methods, the team discovered that some techniques produce materials that perform better than others. This new understanding can help chip manufacturers find ways to better diffuse the heat that leads to device damage and decreased device lifespans.

A team of scientists from the Advanced Manufacturing Technologies Center of the National Technology Initiative (NTI) of Peter the Great St. Petersburg Polytechnic University (SPbPU) developed a mathematical model of an 'endoprosthesis-skeleton' system. Special attention was paid to the geometry and internal structure of hip bones.
