Radial Velocity Variations of HR 6684
Publications of the Astronomical Society of the Pacific, 1974Photometric and spectroscopic observations of HR 6684 confirm the photometric period of 0.139890 day and show a well-defined velocity variation with an amplitude of 11.3 km sec-1 in the same period.

Radial Velocity Variations in Cool Supergiants
International Astronomical Union Colloquium, 1984AbstractA 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.

Variations of Origin of Radial Artery
Introduction: Radial artery is the smaller terminal branch of brachial artery arising in the cubital fossa, at the level of the neck of radius. This artery is commonly used to do coronary artery angiography, canulation. Aim: To study variations in the origin of radial artery. Various variations in the origin of radial artery were reported earlier, highP. Nikhila Ratna +4 more

Radial variation of lunar crater rim topography
Icarus, 1977The paper presents results of determinations of variations of rim topography as a function of range from the crater rim for a group of morphologically fresh craters. It is found that the rate at which exterior crater topography converges with the surrounding surface is highly variable among different radial directions at individual craters as well as ...

Radial variation of track damage in polycarbonate
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2004Abstract Several authors reported data showing a differentiated structure of ion tracks in some polymers, when analysed at submicroscopic level. Four zones can be distinguished: core, halo, cross-linking and bulk, at least in tracks produced by ions with specific energies higher than 0.2 MeV/n.

On radial variation of bounded analytic functions
Complex Variables, Theory and Application: An International Journal, 1990Given any positive function r(r) defined on [0.1] and tending to 0 as r →1 we prove that there exists a function f in the algebra 4 of functions analytic on the unit disk Δ and continuous on Δ so that for almost all θ This result, together with an old result of A. Zygmund, shows that the sharp radial variation of H x functions is for almost all θ.

Radial variation of functions in Dirichlet‐type spaces
Mathematika, 1997Let \(W\) 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 ...

Variational method for integrating radial gradient field
Optics and Lasers in Engineering, 2014Abstract We propose a variational method for integrating information obtained from circular fringe pattern. The proposed method is a suitable choice for objects with radial symmetry. First, we analyze the information contained in the fringe pattern captured by the experimental setup and then move to formulate the problem of recovering the wavefront ...

The Radial Velocity Variation of Epsilon Cephei
Publications of the Astronomical Society of the Pacific, 1971The 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.
