Abstract: Global marine vertical deflection is essential for understanding Earth's internal mass and density distribution and improving the long-term inertial navigation accuracy of underwater ...

Four years ago, NASA purposely smashed a spacecraft into a small asteroid to see if they could deflect it—a test to prove humanity could protect Earth from threatening space rocks.

Introduction The importance of conducting qualitative research alongside clinical trials of complex healthcare interventions is well established. There are various ways in which these two ...

Abstract: The conventional aperture-integration surface-integration (AI-SI) method is enhanced for radome analysis in the transmitting mode. First, a quad-tree-based scheme is proposed to discretize ...
