−A newly developed hardness test based on equivalent indentation depth is currently expected to be the only hardness test method that enables seamless evaluations of hardness across different hardness scales in all load ranges from nanoscopic to macroscopic in an industrial friendly manner because the new method is free from the shortcomings of the instrumented indentation method, which require...

PURPOSE To evaluate the reproducibility of central subfield thickness (CST) and volume measurements from optical coherence tomography (OCT) images obtained with Zeiss Stratus and Optovue RTVue, and formulate equations to convert these measurements from RTVue to 'equivalent' Stratus values. METHODS Cross-sectional observational study from 309 eyes of 167 participants with diabetes and at least...

the behaviour of power transformers is very like to ideal ones. their characteristic matrices can not be determined directly, because the elements of the characteristic matrices are either close to infinity or zero. on the other hand, strong coupling between two transformer windings causes the determinant of these matrices to become zero. therefore, conversion of these matrices to each other wi...

Conversion coefficients were calculated for fluence-to-absorbed dose, fluence-to-equivalent dose, fluence-to-effective dose and fluence-to-gray equivalent for isotropic exposure of an adult female and an adult male to tritons ((3)H(+)) in the energy range of 10 MeV to 1 TeV (0.01-1000 GeV). Coefficients were calculated using Monte Carlo transport code MCNPX 2.7.C and BodyBuilder™ 1.3 anthropomo...

Graphics Processing Units (GPUs) is currently a common feature of high performance computing. Languages such as CUDA and Open Computing Language (OpenCL) are such programming models; provide a standard interface for achieving high performance across these GPU devices. However, because of the wide variety of architectural complexities of these GPU devices; often makes difficult to write programs...

To determine quantities for radiation protection against high-energy electrons, such as those from LINAC, the organ dose equivalents and equivalent doses for the human body were calculated using EGS-4 Monte Carlo simulation code and an MIRD-5 mathematical human phantom. Conversion factors for the incident fluence to the organ dose equivalent, to the effective dose and to the effective dose equi...
