A new deghosting method based on the generalized triangulation is presented. First, two intersection points corresponding to the emitter position are obtained by utilizing two azimuth angles and two elevation angles from two jammed 3-D radars (or 2-D passive sensors). Then, hypothesis testing based ...

Mechanical failure modes leading to cracks or breeches in proton exchange membrane fuel cells are driven by mechanical forces associated with swelling from water uptake and shrinkage from dehumidification. To determine the magnitude of compressive mechanical stress imposed by water swelling in a pro...

Traditional data envelopment analysis (DEA) theory assumes that decision variables are regarded as inputs or outputs, and no variable can play the roles of both an input and an output at the same time. In fact, there exist some variables that work as inputs and outputs simultaneously and are called ...

Tangible augmented reality (TAR) technology opens a novel realm which integrates the computergenerated elements into the real word. Its applications into design education have been explored with a limitation to this entire area. TAR offers an innovative learning space by merging digital learning mat...

With respect to security, the use of various terminals in the mobile Internet environment is problematic. Traditional terminal testing methods cannot simulate actual testing environments; thus, the test results do not accurately reflect the security of terminals. To address this problem, we designed...
