Abstract: A range-separated short-range DFT (density functional theory) long-range RPA (random-phase approximation) electron correlation method has been derived that is fully optimised with respect to variations in the orbitals and orbital eigenvalues. The method both exhibits… read more here.

DOI: 10.1016/j.conbuildmat.2017.04.130
Abstract: Abstract Cracking is one of the main reasons for asphalt pavement damage. Because of the anisotropism of asphalt mixtures, traditional experimental methods cannot analyze displacement and strain fields accurately. A full-field, noncontact measurement technology—the digital… read more here.

DOI: 10.2174/2352096513999200606224154
Abstract: In Computed Tomography (CT), it is often not possible for the subject to remain stationary during a scan. Unfortunately, a patient motion would result in degraded spatial resolution and image artifacts. It is desirable to… read more here.
