effect of different fruit position on postharvest quality of f1 hybrid redfleshed watermelon hi-u 16 was examined. in this study only one main vine was trained and maintained. the plants were allowed to set three fruits naturally at the first (8th - 11th nodes), second (13th - 16th nodes) and third (18th - 21th nodes) position. fruits were harvested at 35 days after anthesis. fruit weight, diam...

In this research, two risk hedging strategies, the option contract and the advance purchase discount contract, are investigated within a manufacturer–retailer two-echelon supply chain context. This study offers three contributions. First, the optimal decisions under the two contracts from the perspectives of both the manufacturer and the retailer are determined. Second, circumstances under whic...

Picking and put-away operations must be executed quickly and eeciently in warehouses within multi-echelon supply chains. The ability to perform these picking and put-away tasks in a timely fashion is a function of the distance the workers must travel within the warehouse. Two analytic methods for estimating the labor requirements associated with these activities are presented. The rst method is...

let $ m , n in mathbb{n}$, $d$ be a division ring, and $m_{m times n}(d)$ denote the bimodule of all $m times n$ matrices with entries from $d$. first, we characterize one-sided submodules of $m_{m times n}(d)$ in terms of left row reduced echelon or right column reduced echelon matrices with entries from $d$. next, we introduce the notion of a nest module of matrices with entries from $d$. we ...

In this paper‎, ‎we decide to select the best center nodes‎ ‎of radial basis functions by applying the Multiple Criteria Decision‎ ‎Making (MCDM) techniques‎. ‎Two methods based on radial basis‎ ‎functions to approximate the solution of partial differential‎ ‎equation by using collocation method are applied‎. ‎The first is based‎ ‎on the Kansa's approach‎, ‎and the second is based on the Hermit...

February 21, 2017 Abstract Recently, an idling mechanism has been introduced in the context of distributed first order methods for minimization of a sum of nodes’ local convex costs over a generic, connected network. With the idling mechanism, each node i, at each iteration k, is active – updates its solution estimate and exchanges messages with its network neighborhood – with probability pk (p...

Clark and Scarf [1960] characterize optimal policies in a two-echelon, twolocation inventory model. We extend their result to the infinite-horizon case (for both discounted and average costs). The computations required are far easier than for the finite horizon problem. Further simplification is achieved for normal demands. We also consider the more interesting case of multiple locations at the...
