Effects of Media Non-Uniformity on Electrostatic Transfer in Electrophotography
The effects of spatial non-uniformity in material parameters on the electrostatic transfer of toners from photoreceptors to receiving media are investigated with the charge transport model of dielectric relaxation in the receiver. The parameters considered include intrinsic charge density, charge mobility, charge injection strength and permittivity of the receiving media. The detrimental effect...
متن کاملStress Non-uniformity in Hollow Cylindrical Test Specimens
Different levels of stress non-uniformity usually occur in test specimens of different dimensions and aspect ratios. The effect of the choice of dimensions on the level of stress nonuniformity for hollow cylindrical specimens was studied using a linear elastic analysis during the development of a new hollow cylinder apparatus. Earlier researchers have assumed slightly different variations in th...
متن کاملSensitivity matrix and reconstruction algorithm for EIT assuming axial uniformity.
In electrical impedance tomography (EIT) two-dimensional models continue to be applied despite their known inability to provide correct reconstruction. In this paper, a reconstruction algorithm that assumes a translationally invariant conductivity distribution is described. A more precise forward solver is obtained by taking off-slice currents into consideration. An appropriate sensitivity matr...
متن کاملA multivariate uniformity test for the case of unknown support
A test for the hypothesis of uniformity on a support S ⊂ R is proposed. It is based on the use of multivariate spacings as those studied in Janson (1987). As a novel aspect, this test can be adapted to the case that the support S is unknown, provided that it fulfils the shape condition of λ-convexity. The consistency properties of this test are analyzed and its performance is checked through a ...
متن کاملA Competitive Test for Uniformity of Monotone Distributions
We propose a test that takes random samples drawn from a monotone distribution and decides whether or not the distribution is uniform. The test is nearly optimal in that it uses at most O(n √ log n) samples, where n is the number of samples that a genie who knew all but one bit about the underlying distribution would need for the same task. Conversely, we show that any such test would require Ω...
