We show that a particular noncommutative geometry, sometimes called angular or $\rho$-Minkowski, requires the spectrum of time be discrete. In this space variable is not commuting with in cylindrical coordinates. The possible values can take go from minus infinity to plus infinity, equally spaced by scale noncommmutativity. Possible self-adjoint extensions "time operator" are discussed. They gi...
A fourth order formulation of the displacement discontinuity method (DDM) is proposed for the crack analysis of brittle solids such as rocks, glasses, concretes and ceramics. A fourth order boundary collocation scheme is used for the discretization of each boundary element (the source element). In this approach, the source boundary element is divided into five sub-elements each recognized by a ...
