We present new diagnostic metrics to probe the dynamical state of galaxy clusters. These novel rely on computation power spectra matter and gas distributions their cross-correlation derived from cluster observations. This analysis permits us cross-correlate fluctuations in distribution, inferred high-resolution lensing mass maps Hubble Space Telescope (HST) data, with those emitted X-ray surfac...

One of the most important problems for distribution companies is to find the best locations for depots and to find proper routes for transportation vehicles and to optimize supply network. This study intends to develop a model for the problem of location-routing in post offices. So, a new Bi-Objective Location-Routing Problem for Locating Town Post Office and Routing Parcels is defined. This pr...
