the process of economic globalization and integration has had a tremendous growth in recent years and the convergence of various economic sectors, including the financial markets is increasingly in the spotlight. this increasing trend has strengthened investors' interests in the subject of convergence among the world's stock markets and investors experimentally show a passion for unde...

Optimum irrigation is very important for nursery stock management of F1-hybrid oil palm (Elaeis guineensis Jacq.), constituting a major production cost. Generally, over watering of nursery stock can be a cause of loss of productivity. The aim of this study was to investigate the physiological and biochemical responses of oil palm nursery stock to reduced soil water content (SWC) and during the ...

W consider the optimal production and inventory control of an assemble-to-order system with m components, one end-product, and n customer classes. A control policy specifies when to produce each component and, whenever an order is placed, whether or not to satisfy it from on-hand inventory. We formulate the problem as a Markov decision process and characterize the structure of an optimal policy...

This study investigates the effect of nursing on the incidence of breast tumors in mice. The A inbred high-cancer line was used as control and newborn young of A stock mothers were removed and fostered by females of the low-tumor C57 Black or CBA lines. It was apparent that the fostered mice and the progeny of the noncancerous fostered animals lived considerably longer than did mice from the ...

Inventory theory provides methods for managing and controlling inventories under different constraints and environments. We consider a class of production/inventory control problems that has a single product and a single stocking location, when a stochastic demand with a known non-stationary probability distribution is given. A control policy for this type of inventory system is the one where t...

The purpose of this paper is to investigate whether stock/flow failures persist in naturalistic decision making environments. A tangible stock/flow experiment is used in this study, which asks participants to pour a certain amount of water into a glass through a funnel in an as short time as possible. Findings are that people on average do not perform better in a tangible stock/flow task than i...

In this paper, we consider a serial two-echelon periodic review inventory system with two supply modes at the most upstream stock point. As control policy for this system, we propose a natural extension of the dual-index policy, which has three base-stock levels. We consider the minimization of long run average inventory holding, backlogging, and both per unit and fixed emergency ordering costs...

Visualization of stock exchange market is one of the prominent applications of information visualization. Although there are several research results which visualize longterm stock price movements, visualization of daytime stock price movements is rare. However, it is a very important application domain, since the fact that there is no statistical method of predicting daytime stock prices indic...
