Fourier Cosine Differential Quadrature Method for Beam and Plate Problems
, 2011 In this paper, we combined the Fourier cosine series and differential quadrature method (DQM) in barycentric form to develop a new method (FCDQM), which is applied to the 1D fourth order beam problem and the 2D thin isotropic plate problems. Furthermore,

Combined Metasurface and Metamaterial Passive Transmit Lens and Receive Array for 3 T
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Metasurfaces (MSs) and metamaterials (MMs) can reduce transmit field nulls caused by wavelength effects at higher MR field strengths. We present a layered MM and MS resonant structure that improves transmit field performance when used as a combined slab (i.e., the metaslab), while also operating as a receive array.

Near Surface Geophysics, EarlyView.Abstract This study focuses on characterising a strong and unexpected anomaly observed during an electromagnetic induction (EMI) survey conducted on the chalk cliff plateau at Sainte‐Marguerite‐sur‐Mer, in the Normandy region, France. The site was selected for a long‐term study of chalk cliff coastal erosion that began in 2017 and has been studied for ...

Latin American Journal of Solids and StructuresAs a first endeavor, bending analysis of tapered nano wires with circular cross section is investigated. In this research, nonlocal elasticity theory based on Euler-Bernoulli beam theory is used to formulate the equations. Differential quadrature method (
