A fast non-convex low-rank matrix decomposition method for potential field data separation is presented. The singular value of the large size trajectory matrix, which also a block Hankel obtained using randomized algorithm in matrix-vector multiplications are implemented with minimal memory storage. This integrated into \begin{docum...

This paper studies a model of social contest between two large groups, in which individual agents can choose whether or not to actively support their group. They become active supporters if they expect their group to win with a sufficiently high probability. The identity of the winner is decided according to a deterministic social rule that is a function of the groups’ strengths and activity ra...

Abstract In order to approximate Gibbs energy functions, a semi-automated framework is introduced for binary and ternary material systems, using Calphad databases. To generate formulations by means of second-order polynomials, the includes precise approach. Furthermore, an optional extensional step enables modeling systems in which direct generation leads unsatisfactory results representation t...

Edge enhancement is a frequently used transformation of potential field data. Its goal to sharpen the position subsurface structures. Here we propose new method enhance edges sources causing anomalies called normalized Harris filter (NHF), which based on and amplitude balance. Three synthetic data sets are evaluate performance proposed approach. The presented approach provides better estimation...

this paper presents numerical calculations for podded propulsion system using vortex theory and potential panel method. the method discretizes the surface boundary of the body (propeller +pod+strut) and obtained the vortex and propeller surface and potential on strut and pod. a model propeller and strut are considered for these calculations and the results of pressure distribution, flow field a...
