Electron Acceleration for X-ray Production Using Paired Pyroelectric Crystals
The exposure of pyroelectric crystals to a heating cycle in near-vacuum conditions has been shown to be a viable method of producing x-rays. The z-negative face of the crystal forms a positive charge as the crystal heats, and a negative charge as it cools. The opposite is true for the z-positive face. Literature has shown that this charge is great enough to accelerate electrons to energies of u...
متن کاملAlternatives for providing highly reliable access to X . 25 networks
Public and private packet-switching networks (PSNs) are being developed or planned throughout the world-for example in Canada (DATAPAC), the U.S. (TELENET), France (TRANSPAC), the U.K. (EPSS), Japan (DDX), Spain, Netherlands and others. 7 Such an explosive development of data communications services is one of the means for attaining the near-perfect availability required from future distributed...
متن کاملModeling Paired Ordinal Response Data
About 25 years ago, McCullagh proposed a method for modeling univariate ordinal responses. After publishing this paper, other statisticians gradually extended his method, such that we are now able to use more complicated but efficient methods to analyze correlated multivariate ordinal data, and model the relationship between these responses and host of covariates. In this paper, we aim to...
متن کاملPaired Accelerated
The geometrical and quantum mechanical basis for Davies' and Unruh's acceleration temperature is traced to a type of quantum mechanical (\achronal") spin. Its existence and deenition are based on pairs of causally disjoint accelerated frames. For bosons the expected spin vector of monochromatic particles is given by the \Planckian power" and the \r.m.s. thermal uctuation" spectra. Under space-t...
متن کاملPaired- and induced paired-domination in (E, net)-free graphs
A dominating set of a graph is a vertex subset that any vertex belongs to or is adjacent to. Among the many well-studied variants of domination are the so-called paired-dominating sets. A paired-dominating set is a dominating set whose induced subgraph has a perfect matching. In this paper, we continue their study. We focus on graphs that do not contain the net-graph (obtained by attaching a pe...
