Estimation of the depth-variant seismic wavelet based on the modified unscaled S-transform

Frontiers in Earth Science
Seismic inversion is one of the key techniques used for reservoir characterization. Depth-domain seismic inversion eliminates the cumulative errors associated with depth-to-time and time-to-depth conversions, thus providing geologists and reservoir ...

Fast computation of sine/cosine series coefficients of associated Legendre function of arbitrary high degree and order

Journal of Geodetic Science, 2018
In order to accelerate the spherical/spheroidal harmonic synthesis of any function, we developed a new recursive method to compute the sine/cosine series coefficient of the 4π fully- and Schmidt quasi-normalized associated Legendre functions.

Importance of Initial Vortex Wavenumber‐1 Asymmetries to Tropical Cyclone Intensification: Idealized Numerical Experiments

Geophysical Research Letters
Considerable asymmetries in the tropical cyclones (TCs) inner core are frequently observed during the intensification phase. However, these asymmetric structures are often not well represented in the initialization of most operational forecasting models.

Wavenumber-dependent transmission of subthreshold waves on electrical synapses network model of Caenorhabditis elegans

eLife
Recent experimental studies showed that electrically coupled neural networks like in mammalian inferior olive nucleus generate synchronized rhythmic activity by the subthreshold sinusoidal-like oscillations of the membrane voltage.

Diagnostics and control of wavenumber stability and purity of tunable diode lasers relevant to their use as local oscillators in heterodyne systems [PDF]

Initial operation of the tunable diode lasers (TDL) showed that it was not possible to adjust the wavenumber to one selected a priori in the TDL tuning range.

A Three-Dimensional Range Migration Algorithm for Downward-Looking 3D-SAR with Single-Transmitting and Multiple-Receiving Linear Array Antennas

EURASIP Journal on Advances in Signal Processing, 2010
This paper presents a three-dimensional (3D) range migration algorithm (RMA) suitable for downward-looking 3D-SAR with single-transmitting and multiple-receiving linear array antennas (STMR-LAA).

Lumley's energy cascade dissipation rate model for boundary-free turbulent shear flows [PDF]

True dissipation occurs mainly at the highest wavenumbers where the eddy sizes are comparatively small. These high wavenumbers receive their energy through the spectral cascade of energy starting with the largest eddies spilling energy into the smaller ...

Longitudinal harmonic components in the Martian upper atmosphere observed by SPICAM and their possible tidal origins

Astronomy & Astrophysics
Context. The longitudinal variations of temperature and pressure in the upper atmosphere of Mars provide important observational constraints on atmospheric waves, including thermal tides. Aims.
