In this paper, two new formulations of the steady-state probability distribution of the number of customers in an M/Er/1 queue system are presented. On one hand, a new recurrent method which is numerically stable and computationally more efficient than the existing ones, in terms of memory and...

An analytic model for the I–V characteristics of a symmetric, undoped, double gate MOSFET is presented. The model is two-dimensional and extends recent work by Chen and Taur. The formulae involve the LambertW function recently used by Ortiz-Conde to obtain threshold voltage approximations of...
