Recent improvements in Hurricane Imaging Radiometer’s brightness temperature image reconstruction
NASA MSFCs airborne Hurricane Imaging Radiometer (HIRAD) uses interferometric aperture synthesis to produce high resolution wide swath images of scene brightness temperature (Tb) distribution at four discrete C-band microwave frequencies (4.0, 5.0, 6.0 ...

A theoretical study on resistance of electrolytic solution: Measurement of electrolytic conductivity
We propose a theoretical approach to determine the conductivity of electrolytic solution using sine waveform voltage as a triggering signal. The approach is based on the acquisition of the complex impedance in two-electrode conductance cell by analyzing ...

Solution of 3D contact problems using spline interpolation
A three-dimensional elastic contact problem is examined. It is assumed that the displacements and deformations are small and the supposed zone of the contact domain must be single-connected, and surrounded by a smooth closed curve.
