A new approach to multipath correction of constant modulus signals

, 1983
An adaptive digital filtering algorithm that can compensate for both frequency-selective multipath and interference on constant envelope modulated signals is presented.

High-modulus, high-conductivity nanostructured polymer electrolyte membranes via polymerization-induced phase separation.

Nano letters (Print), 2014
The primary challenge in solid-state polymer electrolyte membranes (PEMs) is to enhance properties, such as modulus, toughness, and high temperature stability, without sacrificing ionic conductivity.

Size dependence of Young's modulus in ZnO nanowires.

Physical Review Letters, 2006
We report a size dependence of Young's modulus in [0001] oriented ZnO nanowires (NWs) with diameters ranging from 17 to 550 nm for the first time. The measured modulus for NWs with diameters smaller than about 120 nm is increasing dramatically with the ...

On the generalized modulus

The Ramanujan Journal, 2016
The generalized modulus has numerous applications in geometric function theory and analytic number theory. In this paper, we study the monotonicity and convexity of the generalized modulus and obtain sharp functional inequalities for this function. Our results are the extensions of some well-known inequalities of the modulus of the Grotzsch ring.

The elastic modulus for bone

Journal of Biomechanics, 1974
Abstract The elastic moduli for human and bovine bone specimens were determined by compression and tension tests and compared. No statistically significant difference was found between the moduli determined in the two loading modes.

Mechanical properties of shale-gas reservoir rocks — Part 2: Ductile creep, brittle strength, and their relation to the elastic modulus

, 2013
We studied the elastic moduli, ductile creep behavior, and brittle strength of shale-gas reservoir rocks from Barnett, Haynesville, Eagle Ford, and FortSt. John shale in a series of triaxial laboratory experiments.

The relations between the shear modulus, the bulk modulus and young's modulus for polycrystalline metallic elements

Materials Science and Engineering, 1980
Abstract The experimental values available in the literature for the shear modulus, the bulk modulus and Young's modulus of polycrystalline f.c.c., b.c.c. and h.c.p. metallic elements were critically evaluated. It was shown that simple relations exist between the elastic moduli of polycrystalline metals: G/E = a, G/B = b, and E/B = c.

Variable-modulus orthodontics

American Journal of Orthodontics, 1981
Traditionally, orthodontists have varied the size of the wire in order to produce a range of light to heavy forces. A new approach to force control in presented which allows wire size to remain relatively constant and the material of the wire is selected on the basis of clinical requirements.
