Abstract During the high-speed flight of aircraft, cabin body will bear aerodynamic loads, engine thrust structural and equipment component mass inertial loads. At same time, thermal loads be generated due to high speed flight. With development hypersonic aircraft technology, demand for multi-field coupling test is more common. Therefore, it necessary carry out technical verification mechanics ...

We show that the two-point cross-correlation of potential-field recordings is proportional to the Green’s function between the two points. This holds under the condition that spatially and temporally uncorrelated quasi-static noise sources exist throughout the volume. Natural fluctuations, such as thermal noise, may occur that satisfy the necessary conditions. When these fluctuations are random...

We demonstrate that the static ground state atom, which interacts with a conformally coupled massless scalar field in the de Sitter invariant vacuum, can obtain a position-dependent energy-level shift and this shift could cause a Casimir-Polder-like force on it. Interestingly no such force arises on the inertial atom bathed in a thermal radiation in the Minkowski universe. Thus, although the en...

Collaborative Filtering (CF) is one of the widely used methods for recommendation problem. The key idea is to predict further the interests of a user (ratings) based on the available rating information from many users. Recently, matrix factorization (MF) based approaches, one branch of collaborative filtering, have proven successful for the rating prediction issues. However, most of the state-o...

Thermal conductivity of superconducting MgB 2 was studied in both the superconducting and the normal state region. The latter is almost equally determined by the electronic-and the lattice contribution to the total thermal conductivity. In the superconducting state, however, the lattice contribution is larger. The electronic thermal conductivity below T c was derived from the experimental data ...

A quantum mechanical path integral derivation is given of a thermal propagator in non-static Gui spacetime. The thermal nature of the propagator is understood in terms of homotopically non-trivial paths in the configuration space appropriate to tortoise coordinates. The connection to thermal emission from collapsing black holes is discussed. Typeset using REVTEX Supported by the Société Académi...

The paper reviews the applicability of Debye-Waller factors and of Lamb factors to the non-resonant and resonant elastic scattering of X-rays, gamma-rays and thermal neutrons, emphasizing temporal aspects in the interactions. The influence of static disorder upon elastic scattering, in particular upon resonance scattering, is likewise treated. The scattering of X-rays, y-rays and thermal neutro...
