Abstract The measurement of the macroscopic properties a neutron star, whether in binary or an isolated system, provides us with key opportunity to place stringent constraint on its equation state. In this paper, we perform Bayesian model selection wide variety star equations state using multi-messenger observations. particular, (i) use mass and tidal deformability measurements from two merger ...

With the rapid development of UAVs (Unmanned Aerial Vehicles), abnormal state detection has become a critical technology to ensure flight safety UAVs. The position and orientation system (POS) data, etc., used evaluate UAV status are from different sensors. traditional model ignores difference POS data in frequency domain during feature learning, which leads loss key information limits further ...

Applications of multi-state approach to the reliability evaluation of systems composed of independent components are considered. The main emphasis is on multi-state systems with degrading components because of the importance of such an approach in safety analysis, assessment and prediction, and analysing the effectiveness of operation processes of real technical systems. The results concerned w...

in this study, a new stochastic model is proposed to deal with a multi-product, multi-period, multi-stage, multi-site production and transportation supply chain planning problem under demand uncertainty. a two-stage stochastic linear programming approach is used to maximize the expected profit. decisions such as the production amount, the inventory level of finished and semi-finished product, t...

In recent years, pricing and coordination among manufacturers, suppliers, retailers in multi-level supply chains (SCs) have attracted researchers’ attention. Product can be considered one of the main aspects management SCs. The lack a proper strategy leads to low sales numbers, customers, market share, profit. present study aimed at modeling optimal SC, including retailers, where customers plac...

in this research, we address the application of uncertaintyprogramming to design a multi-site, multi-product, multi-period,closed-loop supply chain (clsc) network. in order to make theresults of this article more realistic, a clsc for a case study inthe iron and steel industry has been explored. the presentedsupply chain covers three objective functions: maximization ofprofit, minimization of n...
