Elastic anti-plane shear waves can be refracted negatively when they are transmitted across an interface between a homogeneous substrate and transverse periodic laminate. To achieve pure negative refraction, the frequency of source should lower than upper limit second transition zone harmonic spectrum An effective way to control location zones is consider canonical configuration for laminate, c...

We study the dynamics of viscoelastic materials coupled by a common cohesive interface (or, equivalently, two single domains separated prescribed crack) in anti-plane setting. ...

Abstract With the development of modern surveying and mapping technology, 3D laser scanners are increasingly used for building dip scanning. Building inclination characteristics analyzed using three-dimensional point cloud data binary linear regression. It can easily intuitively obtain building. This method extracted Angle from point, line, plane, surface, other angles. Then, a matching based o...
