A statistical comparison of VHF techniques to study clear-air vertical velocities in the lower atmosphere using the Jicamarca radar
(American Geophysical Union, 1998-11)
We compare two types of VHF vertical velocity measurement techniques using a special configuration of the Jicamarca 50-MHz radar antenna. Zenith (vertically directed single-beam) techniques and spaced antenna (SA) techniques ...

Assessment of Three Spectroscopic Techniques for Rapid Estimation of Calcite in Copper Ore
(IEEE, 2010)
This paper presents the assessment of three spectroscopic techniques, i.e., Raman spectroscopy (RS), ultraviolet fluorescence (UVF) spectroscopy, and energy-dispersive X-ray diffraction (ED-XRD), for measuring calcite ...
Versatile and easy-to-assemble measurement system for impedance-based structural health monitoring
(2011-12-01)
In this paper we present a versatile and easy-to-assemble measurement system for structural health monitoring (SHM) based on the electromechanical impedance (EMI) technique. The hardware of the proposed system consists ...

Acoustic measurement of the bubble Sauter mean diameter d32
(Pergamon-Elsevier Science, 2016)
The importance of gas dispersion variables on the flotation process has led to the development of techniques that allow measuring and monitoring them in flotation. In the case of bubble size, the most used methods are based ...
Comparison of impression techniques and double pouring by dental cast's accuracy. Preliminary clinical-lab trial
(2019-01-01)
Aim: This study compared impression techniques and double pouring by means of cast's accuracy. Methods: For each patient (n=10), impressions from right maxillary canine to first molar were made with acrylic resin trays and ...
Pilot tone aided measurements to extend the bandwidth of radio frequency applications
(Elsevier B.V., 2016)
A technique to extend the effective measurement bandwidth of a non-coherent vector receiver is presented. This bandwidth extension technique relies on the use of a pilot signal (known a priori), which is added on the signal ...
