the history of monetary policy in iran, judging by their performance in keeping the value of the currency, maintaining a steady growth in the gross domestic product, faltering investment, show that monetary policy has not been a portrait of consistent successes, to say the least. as a result of the recent studies two rules have emerged as guideline for policy makers: taylor rule and mccallum ru...

governing is in need of various regulations which can be of different property from the primary decree due to the necessities, expediencies and interventional conditions.  considering the factor of “the entity of rule”, “the function of rule” and “the process of changing legal decree to the rule”, it can be understood that the entity of rule and legal decision particularly in view of criterion ...

contrary to majority of islamic jurists, those who believe in singularity of reality and a certain rule in disagreement cases, in opinion of some of the scholars, the truth and the rule is plural and all of the jurist(modjtahedin) are just. imam mohammad ghazzali is one of these scholars. in his opinion, the theory of proscription (takteah) is incorrect and contradictory. with the exception of ...

The concept of process capability was proposed in early 1970 with the introduction of ‘capability ratio’ by Juran, a world known quality expert. Thereafter almost 40 years have been passed and many indices such as Cp, Cpk and Cpm were developed for measuring process performance. However, many researchers, for example, Kotz and Johnson [1-2] raised concerns about the application of the diversifi...

Solidification rate of the casting affects greatly on the microstructure, quality as well as the mechanical properties of the casting. In centrifugal castings solidification rate is faster compared to gravity casting but still solidification depends on various process parameters like, die wall temperature, pouring temperature of the molten metal, wall thickness of the die and also rotational sp...

A three-dimensional mathematical and physical model coupling with the heat transfer and the flow of molten metal in the centrifugal casting of the high speed steel roll was established by using CFD software FLUENT. It can be used to analyze the distribution of the temperature filed and the flow filed in the centrifugal casting under the gravity, the electromagnetic stirring force and the centri...

This paper describes an industrial application of case-based reasoning (CBR) in the aluminium die-casting industry: the setting of parameters of a pressure diecasting machine for a specific die. As well as describing the application, the paper shows how the system has evolved. The use of cases has given the system a flexibility which has enabled it to be used in ways that were not foreseen at t...
