We consider a supply chain in which an original equipment manufacturer (OEM) authorizes the remanufacturing business to third-party remanufacturer (TPR). The OEM may make investment hold equity TPR. This operation not only enables share profit of TPR as forward shareholding chain, but also improve production efficiency and consequently benefits whole chain. characterize equilibrium decisions al...
Data mining techniques can be used for discovering interesting patterns in complicated manufacturing processes. These patterns are used to improve manufacturing quality. Classical representations of quality data mining problems usually refer to the operations settings and not to their sequence. This paper examines the effect of the operation sequence on the quality of the product using data min...
effects of important operating parameters on product properties and operation of hdpe slurry reactor
in this article, a complete model for the mixed flow slurry reactor for polymerization of ethylene to high density polyethylene in the presence of ziegler-natta catalyst is presented. in addition to the effects of the multiple active sites, the effect of other important parameters such as the catalyst concentration, co-catalyst, hydrogen, monomer, impurities and pressure on the mass-average and...
The dot product operation is very prevalent in sci-entiic computation and has been incorporated as a primitive operation in some languages. Implementation of the dot product operation by a sequence of IEEE standard multiplications and additions does not prevent substantial error accumulation or warn about catastrophic cancellation. The design of a double precision dot product operation is prese...
A new formula for box-minus operation, which separates the box-minus operation into sign and reliability operations, was derived. Its application in the sum-product algorithm (SPA) was also investigated. Both boxplus operation and box-minus operation were divided into sign operation and reliability operation. The results show that on using the box-minus operation, SPA can be implemented with le...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
