This paper represents a long-standing collaboration between Robert Fildes and Brian Kingsman who sadly died before it could be completed. This paper proposes a methodology for examining the effect of demand uncertainty and forecast error on lot sizing methods, unit costs and customer service levels in MRP type manufacturing systems. A number of cost structures were considered which depend on th...

PURPOSE To assess the efficacy of high-frequency ultrasound biomicroscopy (UBM) in improving the accuracy of phakic intraocular lens (pIOL) sizing by increasing the incidence of acceptable postoperative vault. SETTING Multiple private practices, United States. DESIGN Evaluation of diagnostic test or technology. METHODS This prospective multicenter clinical study evaluated eyes having pIOL...

a shortcut procedure as quick, easy-to use method for design and simulation of multicomponent batch distillation is used to predict the operating condition of recovering xylene from solvent in an existing batch distillation column in benzol refinery. the procedure can be used to investigate the effect of the operating parameters on the operation of column for three possible modes of batch disti...

Demand response (DR) can be very useful for an industrial facility, since it allows noticeable reductions in the electricity bill due to the significant value of energy demand. Although most industrial processes have stringent constraints in terms of hourly active power, DR only becomes attractive when performed with the contemporaneous use of battery energy storage systems (BESSs). When this o...

In a dynamic environment, companies face the challenge of increasing customer requirements. Today’s customers expect fast delivery affordable and to their needs tailored products. As result, need act more flexible thus move away from pure make-to-stock make-to-order productions described in literature. Shifting order decoupling point in-between processing strategies such as assemble-to-order ca...

Increasing traffic on the Internet and intranets has raised demands for high-speed, large-scale and cost-effective computer networking techniques. ATM connectionless service provides high-speed, highly scalable, and flexible services because connectionless networks are constructed logically over high-speed ATM networks. This paper described the self-sizing operation for high-speed, large-scale ...

Thermoplastic towpregs are convenient and scalable raw materials for the fabrication of continuous fiber-reinforced thermoplastic matrix composites. In this paper, the potential to employ epoxy and styrene-acrylic sizing agents was evaluated for the making of carbon fiber thermoplastic towpregs via a powder-coating method. The protective effects and thermal stability of these sizing agents were...

BACKGROUND Transcatheter closure of a secundum atrial septal defect (ASD) has become an effective method for surgical treatment. In this study, we evaluated the feasibility and accuracy of intracardiac echocardiography (ICE) for sizing ASDs compared with conventional methods. METHODS Between January 2004 and December 2006, 270 patients underwent transcatheter closure of secundum ASD by using ...
