Confirmation of Two Cyclotron Lines in Vela X-1 [PDF]

, 2002
We present pulse phase-resolved X-ray spectra of the high mass X-ray binary Vela X-1 using the Rossi X-ray Timing Explorer. We observed Vela X-1 in 1998 and 2000 with a total observation time of ~90 ksec.

Measurements of Shear Wave Velocity for Collapsible Soil

Geotechnics
This paper examines the effects of collapsible soil structure on shear wave velocity. The study attempts to simulate hydraulic fill sand deposits, which represent a natural soil deposition process that can result in a collapsible soil structure. A series

Early Dynamical Evolution of the Solar System: Pinning Down the Initial Condition of the Nice Model [PDF]

, 2010
In the recent years, the "Nice" model of solar system formation has attained an unprecedented level of success in reproducing much of the observed orbital architecture of the solar system by evolving the planets to their current locations from a more ...

Intelligent Model for Dynamic Shear Modulus and Damping Ratio of Undisturbed Marine Clay Based on Back-Propagation Neural Network

Journal of Marine Science and Engineering, 2023
In this study, a series of resonant-column experiments were conducted on marine clays from Bohai Bay and Hangzhou Bay, China. The characteristics of the dynamic shear modulus (G) and damping ratio (D) of these marine clays were examined.

Model Dependence of the Properties of S11 Baryon Resonances

, 2003
The properties of baryon resonances are extracted from a complicated process of fitting sophisticated, empirical models to data. The reliability of this process comes from the quality of data and the robustness of the models employed.

A Synthesis Approach for Reproducing the Response of Aircraft Panels to Turbulent Boundary Layer Excitations [PDF]

, 2010
Random wall-pressure fluctuations due to a Turbulent-Boundary Layer (TBL) are a feature of the air flow over an aircraft fuselage under cruise conditions, creating undesirable effects such as cabin noise annoyance.
