摘要: This paper reports on the problem of simultaneously estimating neutron density and reactivity while operating a nuclear reactor. It is solved by using a bank of Kalman filters as an estimator and applying a probabilistic test to determine which filter of the bank has the best performance....
A quantitative description of transition-metal bonding has beenobtained through combined analysis of 9(1) K X-ray and 13(1) Ktime-of-flight neutron diffraction data. It is shown that a simplevalence-orbital model is too crude an approximation adequately todescribe the electron-density distribution...
Apparatus for quantitatively measuring the concentration of a first element or a material containing the first element in a sample (3) containing the first element and other element or elements comprises source (1) yielding neutrons having energy sufficient to produce first gamma -rays by neutron in...
Uranium is the only known element that features a charge-density wave (CDW)and superconductivity. We report a comparison of the specific heat ofsingle-crys... B Mihaila,CP Opeil,FR Drymiotis,... - 《Physical Review Letters》 被引量: 31发表: 2006年 Neutron-diffraction study of the charge...
aneutron logging, density logging and acoustic logging (in case when GWL curves are available). Such GWL suite enabled to define the lithology and porosity of carbonate rocks (dolomite and limestone) and terrigenous rocks. 中子采伐,密度采伐和音响采伐 (,万一,当GWL曲线是可利用的)。 这样GWL随员...
We revisit the problem of radial pulsations of neutron stars by computingfour general-relativistic polytropic models, in which "density" and "adiabaticindex" are involved with their discrete meanings: (i) "rest-mass density" or(ii) "mass-energy density" regarding the density, and (i) "constant...
The neutron scattering and single-crystal synthesis work at Rice was supported by US NSF-DMR-2100741 and by the Robert A. Welch Foundation under grant no. C-1839, respectively. The ARPES work at Rice was supported by the U.S. Department Of Energy (DOE) grant no. DE-SC0021421, the ...
Magnetic structure analysis began with the birth of neutron diffraction, and in itself constitutes one of the unrivaled applications of neutron scattering. The development of this tool has been driven, like many measurement and analysis schemes, by the advent and advancement of computers. Symmetry ana...
