A long cylindrical body of circular cross-section and homogeneous density may float in all orientations around the cylinder axis. It is shown that there are also bodies of non-circular cross-sections which may float in any direction. Apart from those found by Auerbach for ρ = 1/2 there are one-parameter families of cross-sections for ρ = 1/2 which have a p-fold rotation axis. For given p they e...

M subshell X-ray production cross sections have been measured for Ma12, Mb1, Mc, M2–N4 and M1–O23 transitions representing all five M subshells. These experimental cross sections have been compared with the ECUSAR theory of Lapicki and four parameter fits are given to the experiment to theory ratios covering the proton and helium ion energy range from 0.5 to 3 MeV on thin W, Au, Pb, Th and U ta...

We present results from NLO QCD calculations on the production of jets in ep collisions at HERA in a continuous range of photon virtuality Q. Special attention is given to the collinear singularities from the virtual photon and the resolved virtual photon component of the cross sections. Comparisons with dijet data from H1 are shown and the infrared sensitivity of dijet cross sections is discus...

We study deeply virtual Compton scattering (DVCS) on a deuteron target. We model the Generalized Quark Distributions in the deuteron by using the impulse approximation for the lowest Fock-space state. Numerical predictions are given for the unpolarized cross sections for the kinematical regimes relevant for JLab and HERMES at HERA. Differential cross sections show the same pattern as for the pr...

Loading effects of aircraft seats in an electromagnetic reverberating environment are investigated. The effects are determined by comparing the reverberation chamber’s insertion losses with and without the seats. The average per-seat absorption cross-sections are derived for coach and first class seats, and the results are compared for several seat configurations. An example is given for how th...

The processes p p (−) → V1V2 +X → l1l̄1l2l̄2 +X, where Vi = W or Z and li denotes a lepton, are calculated to O(αs). Total and differential cross sections, with acceptance cuts imposed on the final state leptons, are given for the Tevatron and LHC center of mass energies. Inclusive and exclusive 0-jet and 1jet cross sections are given. The transverse momenta spectra of the leptons are significant...

PREVIOUS papers1 in this series have dealt with (a) the evaluation of radial wavefunctions, phase shifts, reduced phases, and differential elastic cross sections for scattering by a L-J (12, 6) potential; (b) the resulting velocity dependence of the differential and total scattering cross sections, with attention given to the Jeffreys-Born OB) approximation for the higher-order phases; (c) the ...

Given parallel (n?1)-dimensional cross-sections of an n-dimensional body, one would like to reconstruct the body. The method based upon distance eld interpolation gives a robust solution to this problem in its ability to deal with any topology in any dimension. Still this method may give undesired solutions to the problem if the changes from one cross-section to the next are big relative to the...
