• #### High fidelity numerical study of nonlinear impact wave propagation: methods, analysis, and applications ﻿

(2014-11-06)
Various systems and structures are subjected to impact loading in industrial and military applications. Many of these impact loads have very high magnitudes and very short durations, resulting in high frequency content. ...
• #### High frequency radio heating of the ionosphere ﻿

(1971)
In this work the effect of a high frequency radio wave incident upon the ionosphere is studied. The changes in the ionospheric parameters are derived, A particular case is examined, namely, the values found for conditions ...
• #### High hardness in the biocompatible intermetallic compound β-Ti3Au ﻿

(2016)
The search for new hard materials is often challenging, but strongly motivated by the vast application potential such materials hold. Ti3Au exhibits high hardness values (about four times those of pure Ti and most steel ...
• #### High ionic strength narrows the population of sites participating in protein ion-exchange adsorption: A single-molecule study ﻿

(2014)
The retention and elution of proteins in ion-exchange chromatography is routinely controlled by adjusting the mobile phase salt concentration. It has repeatedly been observed, as judged from adsorption isotherms, that the ...
• #### HIGH LATITUDE FIELD ALIGNED CURRENTS ﻿

(1983)
Horizontal ionospheric conduction currents are driven by magnetic field-aligned currents generated in the Earth's magnetosphere. Traditional ideas about field-aligned currents imply that most of the higher latitude set of ...
