Generalized gravity-gradient mitigation scheme

چکیده

A major challenge in high-precision light-pulse atom interferometric experiments such as tests of the weak equivalence principle is uncontrollable dependency phase on initial velocity and position atoms presence inhomogeneous gravitational fields. To overcome this limitation, mitigation strategies have been proposed, however, valid only for harmonic potentials or small branch separations more general situations. Here we provide a formula anharmonic perturbation including local effects that vary length scales much smaller than spatial extent probed by originate, e.g., from buildings surround experiment. Furthermore, our results are applicable to interferometer geometries with arbitrary separation allow compensation Coriolis rotating reference frames.

A collusion mitigation scheme for reputation systems

Reputation management systems are in wide-spread use to regulate collaborations in cooperative systems. Collusion is one of the most destructive malicious behaviors in which colluders seek to affect a reputation management system in an unfair manner. Many reputation systems are vulnerable to collusion, and some model-specific mitigation methods are proposed to combat collusion. Detection of col...

dimensional gravity for generalized

A brief survey of the renormalizability of four dimensional gravity for generalized Kodama states. Abstract We continue the line of research from previous works in assessing the suitability of the pure Kodama state both as a ground state for the generalized Kodama states, as well as characteristic of a good semi-classical limit of general relativity. We briefly introduce the quantum theory of f...

Generalized conjugate gradient squared

The Conjugate Gradient Squared (CGS) is an iterative method for solving nonsymmetric linear systems of equations. However, during the iteration large residual norms may appear, which may lead to inaccurate approximate solutions or may even deteriorate the convergence rate. Instead of squaring the Bi-CG polynomial as in CGS, we propose to consider products of two nearby Bi-CG polynomials which l...

The Generalized Reparameterization Gradient

The reparameterization gradient has become a widely used method to obtain Monte Carlo gradients to optimize the variational objective. However, this technique does not easily apply to commonly used distributions such as beta or gamma without further approximations, and most practical applications of the reparameterization gradient fit Gaussian distributions. In this paper, we introduce the gene...

Generalized Conjugate Gradient Squareddiederik

The Conjugate Gradient Squared (CGS) is a well-known and widely used iterative method for solving non-symmetric linear systems of equations. In practice the method converges fast, often twice as fast as the Bi-Conjugate Gradient (Bi-CG) method. However, during the iteration large residual norms may appear, which may lead to inaccurate approximate solutions or may even deteriorate the convergenc...
