This paper deals with the existence of solutions a p-biharmonic pseudo parabolic partial differential equation logarithmic nonlinearity in bounded domain. We prove global weak using Faedo-Galerkin method and applying concavity approach, that blow up at finite time. Further, we provide maximal limit for blow-up

We compute the non-linearity of Boolean functions with Gröbner basis techniques. Moreover, we extend our approach to classify functions with maximum non-linearity.

Introduction of new communication standards makes specifications given to RF surface and bulk acoustic wave (SAW/BAW) devices tougher and tougher. For example, futher improvement of the device linearity is demanded without increasing the device size. Nevertheless, it is still unclear where and how the non-linearity occurs. For finding origin(s) of the very weak non-linearity, its measurement sy...
