We propose relaxing the restricted form of faithful rounding used in prior 32-bit Logarithmic Number System (LNS) implementations. Unrestricted faithful rounding yields a three-to six-fold savings in VLSI ROM size (or four-to six-fold savings in FGPA table size) with only modest increase in error. This can be acceptable for the DSP and multimedia applications in which the non-standard LNS is a ...

This paper introduces a high level language that allows for the specification and manipulation of solver independent models and allows for easily generating complex solvers in the Comet language. As Constraint Programming (CP) techniques have increased in complexity, it has become more di cult and time consuming to implement models that take advantage of state-of-the-art modeling techniques and...

A logarithmic residue is a contour integral of the (left or right) logarithmic derivative of an analytic Banach algebra valued function. Logarithmic residues are intimately related to sums of idempotents. The present paper is concerned with logarithmic residues and sums of idempotents in the Banach algebra generated by the compact operators and the identity in the case when the underlying Banac...

The logarithmic model offers new tools for image processing. An efficient method for image enhancement is to use an affine transformation with the logarithmic operations: addition and scalar multiplication. We define some criteria for automatically determining the parameters of the processing and this is done via mean and variance computed by logarithmic operations. keywords : logarithmic image...

In logarithmic conformal field theory, primary fields come together with logarithmic partner fields on which the stress-energy tensor acts non-diagonally. Exploiting this fact and global conformal invariance of two-and three-point functions, operator product expansions of logarithmic operators in arbitrary rank logarithmic conformal field theory are derived.
