ABSTRACT An E-ring is a ring that is naturally isomorphic to the endomorphism ring of its additive group. E-rings with various properties have been constructed in the literature; we now consider superdecomposable E-rings. More generally, we construct superdecomposable algebras A over integral domains R, which are at the same time E(R)-algebra in the sense that the ring of R-endomorphisms of the underlying R-module structure is canonically isomorphic to A. We also establish the existence of arbitrarily large superdecomposable modules over such algebras. 相似文献

Gas separation membrane cascades I. One-compressor cascades with minimal exergy losses due to mixing
In this first part of this two part paper, attention is paid to the one-compressor cascades with minimal exergy loss due to mixing of streams with different compositions. The desire to avoid mixing losses leads to the development of several new binary gas separation process schemes with no exergy losses due to mixing of streams with different compositions. These schemes are simulated and compared with the “series type two unit separation cell” for higher purity/recovery separations, and with other conventional schemes for enrichment or rejection of the more permeable component. These comparisons show that schemes with no mixing losses are much more efficient than conventional schemes in most cases, although they are only marginally more efficient for low pressure side feed schemes with high permeate purity requirements. 相似文献

We generalize Casselman's pairing to p-adic reductive symmetric spaces and study the asymptotic behaviour of certain generalized coefficients. We also prove an analogue of a lemma due to Langlands which allows us to prove a disjunction result for the Cartan decomposition of the p-adic reductive symmetric spaces. 相似文献
