A spectral wave model coupling a quadtree-adaptive discretisation of the two spatial dimensions with a standard discretisation of the two spectral dimensions is described. The implementation is greatly simplified by reusing components of the Gerris solver (for spatial advection on quadtrees) and WAVEWATCH III (for spectral advection and source terms). Strict equivalence between the anisotropic ...

electronic health record (ehr) is a repository of patient health information shared among multiple authorized users. as a modern method of storing and processing health information, it is a solution for improving quality, safety and efficiency of patient care and health system. however, establishment of ehr requires a significant investment of time and money. while many of healthcare providers ...

This paper extends the concept of an array of THz resonant elements to sets of distributed elements that can be used as the rows of an array.

Dynamic behavior of a circular shaft with geometrical nonlinearity and constant spin, subjected to periodic axial load is investigated. The case of parametric combination resonance is studied. Extension of shaft center line is the source of nonlinearity. The shaft has gyroscopic effect and rotary inertia but shear deformation is neglected. The equations of motion are derived by extended Hamilto...
