Finite size scaling in the solar wind magnetic field energy density as seen by WIND [PDF]

, 2002
Statistical properties of the interplanetary magnetic field fluctuations can provide an important insight into the solar wind turbulent cascade. Recently, analysis of the Probability Density Functions (PDF) of the velocity and magnetic field fluctuations

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Effect of Internal Waves on the Hydrodynamics of a Mediterranean Sea Strait

Journal of Marine Science and Engineering
In the present work, the effects of wind- and tide-induced internal waves in the Rio-Antirio Strait in western Greece were studied by using three-dimensional numerical simulations.

Fluctuating wind and wave simulations and its application in structural analysis of a semi-submersible offshore platform

International Journal of Naval Architecture and Ocean Engineering, 2019
A semi-submersible offshore platform always operates under complex weather conditions, especially wind and waves. It is vital to analyze the structural dynamic responses of the platform in short-term sea states under the combined wind and wave loads ...

Transport of Solar Wind Fluctuations: A Two-Component Model

, 2011
We present a new model for the transport of solar wind fluctuations which treats them as two interacting incompressible components: quasi-two-dimensional turbulence and a wave-like piece.

High-latitude observations of impulse-driven ULF pulsations in the ionosphere and on the ground [PDF]

, 2003
International audienceWe report the simultaneous observation of 1.6?1.7 mHz pulsations in the ionospheric F-region with the CUTLASS bistatic HF radar and an HF Doppler sounder, on the ground with the IMAGE and SAMNET magnetometer arrays, and in the ...

Influence of Solar Wind Parameters on Pickup Ion Beam Instabilities Upstream of Mars: Linear Analysis

The Astrophysical Journal
Linear instability analysis is performed to investigate the influence of solar wind parameters on instabilities driven by a cool pickup ion beam distribution, which is believed to excite the proton cyclotron waves upstream of Mars.

A two-parameter wind speed algorithm for Ku-band altimeters [PDF]

, 2002
Globally distributed crossovers of altimeter and scatterometer observations clearly demonstrate that ocean altimeter backscatter correlates with both the near-surface wind speed and the sea state.

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.
