acoustic reflectance
1reflectance — A measure of reflected acoustic energy as a function of immitance, as in middle ear impedance. * * * re·flec·tance ri flek tən(t)s n the fraction of the total radiant flux incident upon a surface that is reflected and that varies according to the …
2Electro-optical MASINT — is a subdiscipline of Measurement and Signature Intelligence, (MASINT) and refers to intelligence gathering activities which bring together disparate elements that do not fit within the definitions of Signals Intelligence (SIGINT), Imagery… …
3Time-Domain Thermoreflectance — is a method by which the thermal properties of a material can be measured, most importantly thermal conductivity. This method can be applied most notably to thin film materials (up to hundreds of nanometers thick), which have properties that vary …
4Transfer-matrix method (optics) — The transfer matrix method is a method used in optics and acoustics to analyze the propagation of electromagnetic or acoustic waves through a stratified (layered) medium. [Born, M.; Wolf, E., Principles of optics: electromagnetic theory of… …
5Ocean turbidity — Visualisation of the Ocean Turbidity of the ocean just before Hurricane Bob (August 14, 1991) Ocean turbidity is a measure of the amount of cloudiness or haziness in sea water caused by individual particles that are too small to be seen without… …

7Non-invasive intracranial pressure measurement methods — Increased intracranial pressure (ICP) is one of the major causes of secondary brain ischemia that accompanies a variety of pathological conditions, most notably, traumatic brain injury (TBI), stroke, and intracranial hemorrhages. However, aside… …
8Radar MASINT — is one of the subdisciplines of Measurement and Signature Intelligence (MASINT) and refers to intelligence gathering activities that bring together disparate elements that do not fit within the definitions of Signals Intelligence (SIGINT),… …
9Attenuation — This article is about attenuation in physics. For other uses, see Attenuation (disambiguation). In physics, attenuation (in some contexts also called extinction) is the gradual loss in intensity of any kind of flux through a medium. For instance …
10Mimicry — For other uses, see Mimic (disambiguation). Plate from Henry Walter Bates (1862) illustrating Batesian mimicry between Dismorphia species (top row, third row) and various Ithomiini (Nymphalidae, second row, bottom row) In …
