The distance modulus of the Small Magellanic Cloud based on double-mode Cepheids [PDF]

open access: green, 2000
We employ the very recent photometric data of the OGLE project together with stellar atmosphere and linear pulsation models to determine the distance modulus of the Small Magellanic Cloud from its double-mode Cepheids. Based on the requirement of obtaining the same distance modulus DM from the two types of variables (fundamental & first overtone ...

Estimation of track modulus over long distances using artificial neural networks

open access: diamondProcedia Engineering, 2017
Abstract Evaluating the railway track structure and identifying the problematic locations with the urgent need of repair along the thousands of miles of tracks have always been a challenge to the railroad industry. Track foundation modulus (also referred to as the track modulus) is one of the main parameters that affect the track performance, and ...

Some effects of galaxy structure and dynamics on the Fundamental Plane -- II. A Virgo-Fornax distance modulus [PDF]

open access: greenMonthly Notices of the Royal Astronomical Society, 1998
The influence of broken structural homology, and the implied broken dynamical homology, is examined for the Fundamental Plane (FP). Requiring a symmetrical treatment of the FP variables, a bisector method of linear regression was applied, in 3-dimensions, to derive the best FP.

The distance modulus of the Large Magellanic Cloud based on double-mode RR Lyrae stars [PDF]

open access: green, 2000
We use double-mode RR Lyrae (RRd) stars from the MACHO variable star database of the Large Magellanic Cloud (LMC) to estimate its distance, by utilizing photometric data, linear pulsation and stellar atmosphere models. If we set E_(B-V)=0.11 and [M/H]=-1.5 for LMC, we get M-m=18.52 mag, which is in agreement with the value obtained from Galactic ...

Interpretation of Hardness in Pseudobinary Nitrides by Bulk Modulus Estimated from Interatomic Distance

open access: hybridMaterials Science Forum, 2005
Hardness of the pseudobinary transition metal aluminum nitride (T-Al-N) films is improved with increasing the AlN content as far as the B1structure is maintained. A drastic change in the compositional dependence of the hardness corresponds to the phase change of the pseudobinary nitride from B1(NaCl) to B4(wurtzite) structure.
