In this paper, we generalize the capacity-scaling techniques in the design of algorithms for the maximum flow problem. Since all previous scaling max-flow algorithms use only one scale factor of value 2, we propose introducing a double capacity-scaling to imp rove and generalize them. The first capacity scaling has a variable scale factor β and the second uses the value 2. We show that, for dif...

[1] Climate sensitivity (l) is usually defined as a deterministic quantity relating climate forcings and responses. While this may be appropriate for evaluating the outputs of (deterministic) GCM’s it is problematic for estimating sensitivities from empirical data. We introduce a stochastic definition where it is only a statistical link between the forcing and response, an upper bound on the de...

Indefinite symmetric matrices that are estimates of positive definite population matrices occur in a variety of contexts such as correlation matrices computed from pairwise present missing data and multinormal based theory for discretized variables. This note describes a methodology for scaling selected off-diagonal rows and columns of such a matrix to achieve positive definiteness. As a contra...

We present exact results for a lattice model of cluster growth in 1D. The growth mechanism involves interface hopping and pairwise annihilation supplemented by spontaneous creation of the stable-phase, +1, regions by overturning the unstable-phase, −1, spins with probability p. For cluster coarsening at phase coexistence, p = 0, the conventional structure-factor scaling applies. In this limit o...

A scaling technique of numbers in residue arithmetic with the flexible selection of the scaling factor is presented. The required scaling factor can be selected from the set of moduli products of the Residue Number System (RNS) base. By permutation of moduli of the number system base it is possible to create many auxiliary Mixed-Radix Systems (MRS). They serve as the intermediate systems in the...

A radiometric and geometric processing system has been developed as part of the Advanced Land Image(r) Assessment System (ALIAS). A derivative of the ALIAS processing system has also been implemented operationally at EROS to generate Advanced Land Imager (ALI) Level 1 radiometrically and geometrically corrected data products. This system replaces the “calibration pipeline” previously used to ge...

an analytical equation of state was applied to calculate the thermodynamic properties for argon.the equation of state is that of song and mason. it is based on a statistical-mechanical perturbationtheory of the hard convex bodies and can be written as fifth-order polynomial in the density. thereexist three temperature-dependent parameters: the second virial coefficient, an effective molecularvo...
