Ground registration of data from an airborne Multifrequency Microwave Radiometer (MfMR)
The agricultural soil moisture experiment was conducted near Colby, Kansas, in July and August 1978. A portion of the data collected was taken with a five band microwave radiometer. A method of locating the radiometer footprints with respect to a ground based coordinate system is documented. The procedure requires that the airplane's flight parameters along with aerial photography be acquired simultaneously with the radiometer data. The software which documented reads in data from the precision radiation thermometer (PRT Model 5) and attaches the scene temperature to the corresponding multifrequency microwave radiometer data. Listings of the programs used in the registration process are included
On Seismic Waves (Third Paper)
In two previous papers under the present title 1) 2) the authors have presented data on bodily waves. The present paper contains the corresponding data on surface waves (including seismic sea waves), the magnitude and energy of earthquakes, and miscellaneous topics.
The seismograms used were those studied in the previously published investigations; the numbers assigned to individual shocks are as given in the previous papers
Ground registration of data from an airborne scatterometer
A portion of the data for the agricultural soil moisture experiment, conducted near Colby, Kansas, was collected from four scatterometers mounted on an aircraft. A method is outlined for locating the scatterometer footprints with respect to a ground-based coordinate system. The method requires the airplane's flight parameters along with aerial photography acquired simultaneously with the scatterometer data. Listings of the programs used in the registration process are included
On Seismic Waves (Second Paper)
In a first paper under the present title the authors have presented a body of data on travel times. The present paper contains the
corresponding data on amplitudes, periods, velocities, etc., for bodily
waves. It is intended to present data on surface waves in a third paper
Field-Effect Devices Utilizing LaAlO-SrTiO Interfaces
Using LaAlO-SrTiO bilayers, we have fabricated field-effect devices
that utilize the two-dimensional electron liquid generated at the bilayers'
{\textit n}-type interfaces as drain-source channels and the LaAlO layers
as gate dielectrics. With gate voltages well below 1\,V, the devices are
characterized by voltage gain and current gain. The devices were operated at
temperatures up to 100\,{\deg}C.Comment: to be published in Applied Physics Letter
