He analyzed recordings of 81 different birds, measuring the difference in frequency between each note and the next and looking for the same intervals used in diatonic, pentatonic, and chromatic scales.
Since receptors on opposite sides of the body experience stimuli of opposite polarities, this procedure is equivalent to measuring the difference in spike times between receptors at different locations on the body evoked by the same stimulus (Hopkins, 1981).
Finally, salt marsh impacts were estimated by measuring the difference in annual loss costs between properties with and without marshes.
Smart phones currently have fingerprint sensors, based on measuring the difference in capacitance between air and human tissue.
A technique that measures the rotational diffusion of fluorophores by measuring the difference in the polarization of excitation and emission light.
The procedure is very accurate and sensitive when measuring the difference in heat capacity between a solvent and a dilute solution of solute in the same solvent.
It was introduced during World War II as Loran (long-range navigation) A, a system that determines position by measuring the difference in the time of reception of synchronized pulses from widely spaced transmitting stations.
The elemental abundance of a particular element can be determined by measuring the difference in the X-ray absorption just above and just below an absorption edge of that element.
We present a novel and high accuracy (±1°) technique for measuring the difference in phase delay between the positive and negative eigenvectors of a twisted nematic liquid crystal spatial light modulator (LCSLM) as a function of applied voltage.
DNIC's analgesia was assessed by measuring the difference in pain ratings between the two thermode procedures, before and after inducing DNIC by a cold pressure test on the opposite arm.
Carnot showed that you could predict the theoretical maximum efficiency of a steam engine by measuring the difference in temperatures of the steam inside the cylinder and that of the air around it, known in thermodynamic terms as the hot and cold reservoirs of a system respectively.
