22Metamaterial — Negative index metamaterial array configuration, which was constructed of copper split ring resonators and wires mounted on interlocking sheets of fiberglass circuit board. The total array consists of 3 by 20×20 unit cells with overall dimensions …
23Quartz crystal microbalance — A quartz crystal microbalance (QCM) measures a mass per unit area by measuring the change in frequency of a quartz crystal resonator. The resonance is disturbed by the addition or removal of a small mass due to oxide growth/decay or film… …
24Solid solution strengthening — is a type of alloying that can be used to improve the strength of a pure metal. The technique works by adding atoms of one element (the alloying element) to the crystalline lattice another element (the base metal). The alloying element diffuses… …
25Lamé parameters — In linear elasticity, the Lamé parameters are the two parameters * λ, also called Lamé s first parameter . * μ, the shear modulus or Lamé s second parameter .which in homogenous, isotropic materials satisfy Hooke s law in 3D,:sigma=2mu varepsilon …
26Nonimaging optics — (also called anidolic optics)[1][2] is the branch of optics concerned with the optimal transfer of light radiation between a source and a target. Unlike traditional imaging optics, the techniques involved do not attempt to form an image of the… …
27Tire — This article is about tires used on road vehicles, including pneumatic tires and solid tires. For railroad tires, see railway tires. For other uses, see tire (disambiguation) or tyre.Tires, or tyres (in American and British English, respectively) …
28Glass transition temperature — The glass transition temperature, T g, is the temperature at which an amorphous solid, such as glass or a polymer, becomes brittle on cooling, or soft on heating. More specifically, it defines a pseudo second order phase transition in which a… …
29T. V. S. R. Appa Rao — T.V.S.R. Appa Rao is a scientist from India. He is an Emeritus Scientist with over 40 years of experience in Research Development in the areas of structural analysis design, testing, and failure investigations including those due to natural… …
30Diastolic dysfunction — refers to an abnormality in the heart s (i.e. left ventricle s) filling during diastole. Diastole is that phase of the cardiac cycle when the heart (i.e. ventricle) is not contracting but is actually relaxed and filling with blood that is being… …
