The Sliding-Aperture Transform and Its Applicability to Deep-Level Transient Spectroscopy
Applied Sciences, 2022 A mathematical method is presented for the extraction of defect parameters from the multiexponential decays generated during deep-level transient spectroscopy experiments. Such transient phenomenon results from the ionization of charge trapped in defects

Excitation of zero-frequency magnetic field-aligned currents by ionospheric heating [PDF]
Annales Geophysicae, 2011 Time-dependent, three-dimensional numerical simulations of the reduced MHD model describing shear Alfvén waves in the magnetosphere provide an interesting prediction superficially similar to results of several ionospheric heating experiments conducted

Metal Matrix Composite Solar Cell Metallization
E3S Web of Conferences, 2017 Advanced solar cells are moving to ever thinner formats in order to save mass and in some cases improve performance. As cells are thinned, the possibility that they may fracture or cleave due to mechanical stresses is increased. Fractures of the cell can

A Comparison of Sporadic-E Occurrence Rates Using GPS Radio Occultation and Ionosonde Measurements
Remote Sensing, 2022 Sporadic-E (Es) occurrence rates from Global Position Satellite radio occultation (GPS-RO) measurements have shown to vary by a factor of five between studies, motivating the need for a comparison with ground-based measurements.

Characterization of vortex-shedding regimes and lock-in response of a wind turbine airfoil with two high-fidelity simulation approaches [PDF]
Wind Energy ScienceIn this work, the vortex-induced vibration (VIV) phenomenon affecting a wind turbine airfoil section at 90° incidence is analysed with two numerical approaches, a two-dimensional (2D) setup of the airfoil, simulated using the unsteady Reynolds-averaged ...

Ionospheric Research from Space Vehicles [PDF]
Space Science Reviews, 1963 Previous to the advent of artificial satellites, our knowledge of the ionosphere was limited principally to the interpretation of data from the classical ground-based ionosonde and a few rocket measurements of ionizing radiation, electron density and ion composition, all applicable to altitudes below the F2 peak.
