THE IDEALS OF AN IDEAL EXTENSION [PDF]
Journal of Algebra and Its Applications, 2010 Given two unital associative rings R ⊆ S, the ring S is said to be an ideal (or Dorroh) extension of R if S = R ⊕ I, for some ideal I ⊆ S. In this note, we investigate the ideal structure of an arbitrary ideal extension of an arbitrary ring R. In particular, we describe the Jacobson and upper nil radicals of such a ring, in terms of the Jacobson and ...

Fabrication and Simulation of an E-Vehicle [PDF]
E3S Web of ConferencesAn electric vehicle is one that is powered by on-board electric sources and is driven by electric motors. Electric vehicles have emerged only because of the rise in cost of fuels and pollution.

Ideal spatial adaptation by wavelet shrinkage
, 1994 SUMMARY With ideal spatial adaptation, an oracle furnishes information about how best to adapt a spatially variable estimator, whether piecewise constant, piecewise polynomial, variable knot spline, or variable bandwidth kernel, to the unknown function ...

The multiplier ideals of a sum of ideals [PDF]
Transactions of the American Mathematical Society, 2001 We prove that if a _ \underline {\mathbf {a}} , b _ ⊆ O X \underline {\mathbf {b}}\subseteq \mathcal {O}_X are nonzero sheaves of ideals on a complex smooth variety

Bone grafts: which is the ideal biomaterial?
Journal of Clinical Periodontology, 2019 Bovine xenograft materials, followed by synthetic biomaterials, which unfortunately still lack documented predictability and clinical performance, dominate the market for the cranio-maxillofacial area. In Europe, new stringent regulations are expected to

Principal Ideals in the Ideal Lattice [PDF]
Proceedings of the American Mathematical Society, 1972 We show that there cannot be a definition of “principal elements” in the theory of multiplicative lattices so that the notion of principal elements concurs with the notion of principal ideals when interpreted in the ideal lattices of rings.
