Texture Measurements Using the New Neutron Diffractometer HIPPO and their Analysis Using the Rietveld Method

In this paper we describe the capabilities for texture measurements of the new neutron time-offlight diffractometer HIPPO at the Los Alamos Neutron Science Center (LANSCE). The orientation distribution function (ODF) is extracted from multiple neutron time-of-flight histograms using the full-pattern analysis first described by Rietveld. Both, the well-established description of the ODF using sp...

A posteriori $ L^2(L^2)$-error estimates with the new version of streamline diffusion method for the wave equation

In this article, we study the new streamline diffusion finite element for treating the linear second order hyperbolic initial-boundary value problem. We prove a posteriori $ L^2(L^2)$ and error estimates for this method under minimal regularity hypothesis. Test problem of an application of the wave equation in the laser is presented to verify the efficiency and accuracy of the method.

Neutron Star Mass Measurements

There are now about fty known radio pulsars in binary systems, including at least ve in double neutron star binaries. In some cases, the stellar masses can be directly determined from measurements of relativistic orbital eeects. In others, only an indirect or statistical estimate of the masses is possible. We review the general problem of mass measurement in radio pulsar binaries, and criticall...

Performance based assessment of offshore wind turbine platform using the constrained new wave method

The purpose of this study is to provide a more accurate and practical method than static and spectral methods to assess the offshore wind turbines that are loaded with both wave and wind time history, the structure is evaluated by increasing the load intensity in successive steps to the stage of failure and the performance of the platform in different wave patterns are investigated. In this stu...
