This paper presents a new wavelet interpolation Galerkin method for the numerical simulation of MEMS devices under the effect of squeeze film damping. Both trial and weight functions are a class of interpolating functions generated by autocorrelation of the usual compactly supported Daubechies scaling functions. To the best of our knowledge, this is the first time that wavelets have been used a...

{ We develop a framework (employing scaling functions) for the construction of multi-step quasi-Newton methods (for unconstrained optimization) which utilize values of the objective function. The methods are constructed via interpolants of the m + 1 most recent iterates / gradient evaluations, and possess a free parameter which introduces an additional degree of exibility. This permits the inte...

1. Abstract We present an incomplete series expansion (ISE) as a basis for function approximation. The ISE is expressed in terms of an approximate Hessian matrix which may contain second, third and even higher order ‘main’ or diagonal terms, but which excludes ‘interaction’ or off-diagonal terms. From the ISE, a family of approximate interpolating functions may be derived. The interpolating fun...
