abstract. let r be a 2-torsion free ring with identity. in this paper, first we prove that any jordan left derivation (hence, any left derivation) on the full matrix ringmn(r) (n  2) is identically zero, and any generalized left derivation on this ring is a right centralizer. next, we show that if r is also a prime ring and n  1, then any jordan left derivation on the ring tn(r) of all n×n up...

Bridging relations are frequently used to provide engineering aerodynamic predictions in the transitional regime between free-molecular and continuum ows. Such predictions are important for mission studies of high-speed planetary entry vehicles to provide accurate analysis of trajectory dynamics, vehicle stability, and landing footprint. However, empirical parameters in these bridging relations...

Bridging fault extraction and analysis are crucial to deriving high quality bridging fault test generation. As state-of-the-art designs integrate millions of logic gates into a VLSI circuit, a run-time and memory eecient bridging fault extraction approach must be developed to cope with the design complexity. In this paper, a hierarchical bridging fault analyzer-FAULTAN is described. In FAULTAN,...

This paper presents the micromechanical modeling of fiber bridging constitutive law of a discontinuous fiber reinforced composite (DFRC) under cyclic loading. Fiist, the derivation of fiber bridging constitutive law under monotonic loading is briefly reviewed to highlight he approach to obtain the bridging stress carried by randomly distributed discontinuous fibers. Second, the relation between...
