Radial variation of functions in Dirichlet‐type spaces

Mathematika, 1997
Let \(W\) be a positive, increasing and continuous function on \([1,\infty)\) for which (1) \(\sum (W(n))^{-1} =\infty\). A function \(H\) is defined initially on \((0,\pi)\): \[ H(x)= \int_1^{\pi/x} \bigl(W(t) \bigr)^{-1} dt+ \int_1^{\pi/x} \bigl(W (t)\bigr)^{-1 /2} dt\int^\infty_{\pi/x} t^{-1} \bigl(W(t) \bigr)^{-1/2}dt, \] and then extended as an ...

Radial yield variations in semiconductor wafers

IEEE Circuits and Devices Magazine, 1987
Detailed examination of yield data from several different products in two different technologies and two different wafer sizes has shown a pronounced radial dependence. In all cases, the yield profile has a distinct knee starting at about 10 mm from the wafer periphery, dropping steeply within the final 5 mm.

Radial porosity variations in packed beds

AIChE Journal, 1958
AbstractThe radial variation of void fraction in randomly packed beds of spheres, cylinders, Raschig rings, and Berl saddles was investigated. After packing, the beds were filled with paraffin, which was then allowed to solidify. Slabs were cut from the bed, and annular rings were removed by two different experimental techniques.

Effects of radial conductivity variation on the Ponomarenko dynamo

Physical Review E
We study the effects of conductivity variation on the Ponomarenko dynamo. Taking monotonically increasing, decreasing and sinusoidally varying radial profiles, we study the kinematic dynamo problem. The threshold of the dynamo, given by the critical magnetic Reynolds number Rm_{c}, is found to strongly depend on the form of conductivity variation near ...

Radial and Tangential Variation of Deuterium in Hailstones

Journal of the Atmospheric Sciences, 1975
Abstract Radial variations of deuterium content are measured in nine large hailstones from three storms; of tritium content in one of the nine; and tangential variations of deuterium content in a wet-growth layer in five of the nine. Crystal size and air bubble content are noted as well.

VARIATIONS OF STENOSING TENOSYNOVITIS AT THE RADIAL STYLOID PROCESS

The Journal of Bone & Joint Surgery, 1951
At operation, variations have been observed in the relation of the abductor pollicis longus and the extensor pollicis brevis and the aberrant tendon, one to the other. The area of stenosis has also been found to vary.

Radial Velocity Variations in Cool Supergiants

International Astronomical Union Colloquium, 1984
AbstractA survey of F, G, and W supergiants has been carried out with the DAO radial velocity spectrometer, an efficient instrument for detecting low-amplitude velocity variations in cool stars. Observations of 78 stars over five seasons show generally good agreement with OORAVEL results for spectroscopie binaries.

The Radial Velocity Variation of Epsilon Cephei

Publications of the Astronomical Society of the Pacific, 1971
The radial velocity variation of E Cephei was measured on three nights and found to have a variable amplitude. A beat phenomenon is a likely explanation.

Radial variations of G on the galactic scale

Eighth Canadian conference on general relativity and relativistic astrophysics, 1999
We consider the idea of replacing the gravitational constant G by a function depending on the surrounding medium and whose variation would be noticeable on the galactic scale. Such a function in newtonian dynamics allows one to explain the flat region of the rotation velocity curves of many galaxies, without the dark matter hypothesis.
