To better accommodate the highly disparate length scales encountered in geophysical flows, we have extended EULAG with a solution-adaptive moving mesh capability [1]. The development builds on [2], where the authors set forth a time-dependent curvilinear coordinate formulation of the governing PDEs to enable dynamic mesh adaptivity in EULAG. Here, the anelastic flux-form dynamical core of EULAG...

This paper explores pricing and replenishment policies for a high-tech product in a dual-channel supply chain that consists of a brick-and-mortar channel and an internet channel. The unit cost of the product decreases over its short life cycle. Assuming the manufacturer as the Stackelberg leader, the optimal pricing and replenishment policy is analysed mathematically. It is found that there is ...

in this research we have presented a local model for implementing systems engineering activities in optimized acquisition of electronic systems in electronic high-tech industrial. in this regard, after reviewing the literature and the use of documents, articles and latin books, we have collected system acquisition life cycle models from different resources. after considering the criteria of the...

Numerically studies have shown that the bi-stability and backward bifurcation are not automatically connected in epidemic models. In fact, when a backward bifurcation occurs, the disease-free equilibrium may be globally stable or it may support to a stable limit cycle. In this paper, a continuous epidemic model that incorporates density-dependent treatments is analyzed. It is shown that it supp...

Abstract This study demonstrates the importance of accounting for correlated unobserved heterogeneity to correctly identify relevance career and education fertility decisions. By exploiting individual-level life-cycle information on fertility, from large administrative longitudinal datasets, this paper shows that non-linear panel models produce substantially different results than cross-section...

Large-scale energy storage represents a key challenge for renewable energy and new systems with low cost, high energy density and long cycle life are desired. In this article, we develop a new lithium/ polysulfide (Li/PS) semi-liquid battery for large-scale energy storage, with lithium polysulfide (Li2S8) in ether solvent as a catholyte and metallic lithium as an anode. Unlike previous work on ...
