Refinement of the Nacrite S T R U C T U R E

Nacrite crystals from a vug within a matrix ofdickite at Red Mountain near Silverton, Colorado, have a = 8.906(2), b = 5.146(1), c = 15.664(3)/~,,/3 = 113.58(3) ~ V = 657.9(3)/~3, and space group Cc. The structure was solved by direct methods to determine phase angles, followed by electron density maps to locate all atoms. Refinement by least-squares ceased at R = 4.5%. Each 7/~ layer has struc...

نگاشت های R - s - پیوسته

کلاس جدیدی از نگاشتهای پیوسته، به نام نگاشت های R - s - پیوسته ، معرفی میشود. ارتباط میان R - s - پیوستگی با پیوستگی و انواع دیگری ازپیوستگیهای قوی که تاکنون معرفی شده اند، بررسی میشود. سپس ویژگیهای نگاشتهای R - s - پیوسته مورد مطالعه قرار میگیرد.

In recent years, several new architectures have been developed for supporting multimedia applications such as digital video and audio. However, quality-of-service (QoS) routing is an important element that is still missing from these architectures. In this paper, we consider a number of issues in QoS routing. We first examine the basic problem of QoS routing, namely, finding a path that satisfi...

This paper reviews both theoretical and empirical studies of financial transmission rights (FTRs) in the major U.S. wholesale power markets and provides a simple illustrative two-stage model to study the competitive behaviors of electricity generators (wholesale power sellers) and load serving entities (LSEs)(wholesale power buyers) and the welfare effects of FTRs in the restructuring U.S. whol...
