We revisit the problem of estimating center symmetry θ an unknown symmetric density f. Although Stone (1975), Van Eeden (1970), and Sacks (1975) constructed adaptive estimators in this model, their depend on external tuning parameters. In effort to reduce burden parameters, we impose additional restriction log-concavity construct truncated one-step which are under assumption. Our simulations in...

Climate change enforces the implementation of sustainable industrial production with a special focus on pollution reduction, resource management, and energy savings. These goals are addressed by designing advanced control methods using solution an adequately formulated optimization problem. Heat exchangers represent particularly energy-demanding plants that challenging from controller design po...

This paper considers a multi-period, multi-product inventory-routing problem in a two-level supply chain consisting of a distributor and a set of customers. This problem is modeled with the aim of minimizing bi-objectives, namely the total system cost (including startup, distribution and maintenance costs) and risk-based transportation. Products are delivered to customers by some heterogeneous ...
