Determining alloy shrinkage factors is very important for the investment casting process. Casting dimensions can be obtained from numerical simulations of heat transfer and deformation phenomena. The accuracy of the dimensional results depends on heat transfer results. In order to validate heat transfer models, temperature data were obtained during casting of aluminum alloy A356 in shell molds ...

because of important role of development banks in optimal allocation of limited financial resources, their investment efforts must have an objective direction to the achievement of government's strategic goals. in order to get appropriate approaches in its investment, bank of industry and mine (bim) as the only development bank in industry and mine sector, aims to take a general survey amo...

The studies have been carried out with the assistance of Dr. P. S. Tofts, Mr. D. Delpy and Mr. A. Chu of the Department of Medical Physics (UCLSM), and Mr. N.Taylor of Kin...

System-initiated digressive proposals may be used to introduce new and unexpected information into automated telephone services. These digressions may be viewed as particularly pronounced forms of unsolicited interruptions as they contain information not directly related to the caller’s intended activity. In human–human conversation, interruptions are considered to be speech acts which intrinsi...

In 1981, Paris and Wilkie [28] indicated it was an open question whether IΣ0 would satisfy the Second Incompleteness Theorem for Herbrand deduction. We will show that some specially formulated axiomizations for IΣ0 can evade the Herbrandized version of the Second Incompleteness Theorem.

Abstract We consider a coopetitive game model of firms’ behavior in process R&D with entry cost. compare the competitive firms coopetition scenario. In coopetition, engage bargaining to reach binding agreement. find that competition can lead prisoner’s dilemma or chicken between market rivals. The possibility entering agreement resolves above social dilemmas associated behavior. turn, under...
