Kinematical & Chemical Characteristics of the Thin and Thick Disks
I discuss how the chemical abundance distributions, kinematics and age distributions of stars in the thin and thick disks of the Galaxy can be used to decipher the merger history of the Milky Way, a typical large galaxy. The observational evidence points to a rather quiescent past merging history, unusual in the context of the ‘consensus’ cold-dark-matter cosmology favoured from observations of...
متن کاملEdge Crack Studies in Rotating FGM Disks
This article focused on the stress analysis of an edge crack in a thin hallow rotating functionally graded material (FGM) disk. The disk is assumed to be isotropic with exponentially varying elastic modulus in the radial direction. A comprehensive study is carried out for various combinations of the crack length and orientation with the different gradation of materials. The effect of non-unifor...
متن کاملString-Wrapped Rotating Disks
Let the centers of a finite number of disjoint, closed disks be pinned to the plane, but with each free to rotate about its center. Given an arrangement of such disks with each labeled + or −, we investigate the question of whether they can be all wrapped by a single loop of string so that, when the string is taut and circulates, it rotates by friction all the (+)-disks counterclockwise and all...
متن کاملRotating Relativistic Thin Disks
Two families of models of rotating relativistic disks based on TaubNUT and Kerr metrics are constructed using the well-known “displace, cut and reflect” method. We find that for disks built from a generic stationary axially symmetric metric the “sound velocity”, (pressure/density)1/2, is equal to the geometric mean of the prograde and retrograde geodesic circular velocities of test particles mo...
متن کاملCharacteristics of soft magnetic composite material under rotating magnetic fluxes
This paper reports the measurement of magnetic properties of the soft magnetic composite material SOMALOY 500 in a square sample under different patterns of flux density with 2D magnetic excitations. The test system, principle of measurement, magnetic power loss calculation, and methods of correction for misalignment of H surface sensing coils are presented. The experimental results show that a...
