This article summarizes the contributions in this special issue on DiffractionLimited Storage Rings. It analyses the progress in accelerator technology enabling a significant increase in brightness and coherent fraction of the X-ray light provided by storage rings. With MAX IV and Sirius there are two facilities under construction that already exploit these advantages. Several other projects ar...

A company requires finances to carry out its target activities and meet demands. That is why finance also called as the “vital blood” of company. Business facilitates multiple operations that lead mission, objectives It can raise from a variety sources must be analysed properly choose best most appropriate accessible method. The could chosen depending on cost, situation, purpose risk associated...

We propose nite sample tests and on den e sets for models with unobserved and generated regressors as well as various models estimated by instrumental variables methods. The validity of the pro edures is una e ted by the presen e of identi ation problems or \weak instruments", so no dete tion of su h problems is required. We study two distin t approa hes for various models onsidered by Pagan (1...

In the framework of perfect loop nests with uniform dependences, tiling has been extensively studied as a source-to-source program transformation. Little work has been devoted to the mapping and scheduling of the tiles on to physical processors. We present several new results in the context of limited computational resources, and assuming communication-computation overlap. In particular, under ...

The Constrained Application Protocol, CoAP, and related extensions are intended to support machine-to-machine communication in systems where one or more nodes are resource constrained, in particular for low power wireless sensor networks. This document defines publishsubscribe and message queuing functionality for CoAP that extends the capabilities for supporting nodes with long breaks in conne...

In this paper we introduce and study credibility-limited improvement operators. The idea is to accept the new piece of information if this information is judged credible by the agent, so in this case a revision is performed. When the new piece of information is not credible then it is not accepted (no revision is performed), but its plausibility is still improved in the epistemic state of the a...

The cache coherence scheme for a scalable distributed shared memory multiproces-sor should be eecient in terms of memory overhead for maintaining the directories, as well as network latency for a memory request. In this paper, we propose a cache coherence scheme which minimizes the memory access delay and at the same time, reduces the directory overhead by using a limited directory scheme. In t...
