TL;DR: In this article, the lattice constant for aluminum, iron, nickel, copper, molybdenum, palladium, silver, tungsten, platinum, gold, lead and bismuth was determined within 1 percent (03 percent for W) for aluminum.
Abstract: The lattice constant $a$ has been determined within 01 percent (03 percent for W) for aluminum, iron, nickel, copper, molybdenum, palladium, silver, tungsten, platinum, gold, lead and bismuth, by direct comparison with NaCl, $a(\mathrm{NaCl})=2814$A As pure samples as could be obtained were used, from 9955 percent for Ni to 999995 percent for tungsten, and in many cases commercially pure samples were also measured for comparison The results for the purest samples are summarized in Table XIII The density from the x-ray data is in each case (except Al and Ag) greater than the density of the bulk metal as given in the literature, the difference being rather large for Mo (1021 vs 91), for Pd (1225 vs 119) and W (1932 vs 1877) For pure W remarkably sharp lines were obtained For Bi a piece of a single artificial crystal was used

TL;DR: Several polynomial time algorithms finding “good,” but not necessarily optimal, tours for the traveling salesman problem are considered, and the closeness of a tour is measured by the ratio of the obtained tour length to the minimal tour length.
Abstract: Several polynomial time algorithms finding “good,” but not necessarily optimal, tours for the traveling salesman problem are considered. We measure the closeness of a tour by the ratio of the obtained tour length to the minimal tour length. For the nearest neighbor method, we show the ratio is bounded above by a logarithmic function of the number of nodes. We also provide a logarithmic lower bound on the worst case. A class of approximation methods we call insertion methods are studied, and these are also shown to have a logarithmic upper bound. For two specific insertion methods, which we call nearest insertion and cheapest insertion, the ratio is shown to have a constant upper bound of 2, and examples are provided that come arbitrarily close to this upper bound. It is also shown that for any n≥8, there are traveling salesman problems with n nodes having tours which cannot be improved by making n/4 edge changes, but for which the ratio is 2(1−1/n).

TL;DR: In this paper, a light source comprising a phosphor composition and a light emitting device such as an LED or a laser diode was proposed, which can produce white light with pleasing characteristics such as a color temperature of 3000-6500° K, a color rendering index of about 83-87, and a device luminous efficacy of about 10-20 lumens per watt.
Abstract: The invention relates to a light source comprising a phosphor composition and a light emitting device such as an LED or a laser diode. The phosphor composition absorbs radiation having a first spectrum and emits radiation having a second spectrum and comprises at least one of: YBO3:Ce3+,Tb3+; BaMgAl?10?O17:Eu?2+, Mn2+?; (Sr,Ca,Ba)(Al,Ga)?2?S4:Eu?2+?; and Y?3?Al5O12-Ce?3+?; and at least one of: Y?2?O2S:Eu?3+,Bi3+; YVO?4:Eu3+,Bi3+; SrS:Eu2+; SrY2S4:Eu2+; CaLa?2?S4:Ce?3+?; and (Ca,Sr)S:Eu2+. The phosphor composition and the light source together can produce white light with pleasing characteristics, such as a color temperature of 3000-6500° K, a color rendering index of about 83-87, and a device luminous efficacy of about 10-20 lumens per watt.

Journal ArticleDOI
TL;DR: In this article, the authors reviewed recent progress made in the development of polymer dielectrics with high energy storage density, which can potentially lead to significant weight and volume reduction in polymer film capacitors.
Abstract: Polymer film capacitors are critical components in many high-power electrical systems. Because of the low energy density of conventional polymer dielectrics, these capacitors currently occupy significant volume in the entire electrical system. This article reviews recent progress made in the development of polymer dielectrics with high energy storage density, which can potentially lead to significant weight and volume reduction in polymer film capacitors. The increase in energy density is achieved through two approaches, namely (a) the development of novel polymers with high electric polarization and optimized dielectric responses and (b) the development of nanocomposites containing polymer matrixes with high breakdown strength and inorganic nanofillers with high polarization. Promising progress has been made through both strategies, resulting in a maximum energy density of >30 J/cm3, which is at least 5 times higher than those of conventional polymer dielectrics. The state-of-the-art manufacturing method...

TL;DR: Incomplete failure data consisting of times to failure on failed units and differing running times or unfailed units are called multiply censored as discussed by the authors, and data on units operating in the field, for example, are usually multiply censored.
Abstract: Incomplete failure data consisting of times to failure on failed units and differing running times or unfailed units are called multiply censored. Data on units operating in the field, for example, are usually multiply censored. Presented in this paper ..
