2014 The longitudinal magnetoresistance is calculated in the quantum limit in the case of a point like interaction between electrons and donors. We account for the influence of the bound states on 03C3zz The position and width of donor states are derived, and the effects of collision broadening are discussed.

This paper presents analytical results on longitudinal power profile estimation (PPE) methods, which visualize signal evolution in optical fibers at a coherent receiver. The PPE can be formulated as an inverse problem of the nonlinear Schrödinger equation, where coefficient (and thus power) is reconstructed from boundary conditions, i.e., transmitted and received signals. Two types methods are ...

Lattice Boltzmann equations using multiple relaxation times are intended to be more stable than those using a single relaxation time. The additional relaxation times may be adjusted to suppress non-hydrodynamic modes that do not appear directly in the continuum equations, but may contribute to instabilities on the grid scale. If these relaxation times are fixed in lattice units, as in previous ...

Methods for calculating Available Transfer Capability (ATC) of the transmission systems may be grouped under Static and Dynamic methods. This paper presents a fast dynamic method for ATC calculations, which considers both Transient Stability Limits and Voltage Stability Limits as terminating criteria. A variation of Energy Function Method is used to determine the transient stability limit and t...

Placing column lap-splice in the locations of possible nonlinear deformation may adversely affect the structures response to strong ground motions. Localization of damage in splice zone may change the structural response and prevent the load redistribution and development of a uniform pattern of nonlinear excursions among the various members. Validated by existing laboratory experiments, this s...
