In this paper, we consider a dynamic stochastic inventory model with fixed inventory holding and shortage costs in addition to a fixed ordering cost. WE discuss a sufficient and necessary condition for an (s,S) policy to be optimal in the class of such stochastic inventory models. Furthermore, we explore how such a sufficient and necessary condition can be rewritten when the demand distribution...

Nasta’leeq is a bidirectional, diagonal, non-monotonic, cursive, highly context-sensitive and very complex writing style for languages like Urdu, Punjabi, Balochi and Kashmiri. Each is written in a variant of the Perso-Arabic script. The style is characterized by well-formed orthographic rules that are passed down from generation to generation of calligraphers and old manuscripts. It is present...

ABSTRACT- Drying has been used for the preservation of fruits since ancient times. Dried apricot reduces the damages, weight and volume losses, packaging space, storage and handling costs. In this paper, the effects of hot air dryer on an Iranian apricot cultivar ”Noori” have been investigated. The experiment was conducted at three temperatures (30, 40 and 50oC), three fruit thicknesses (5, 10 ...

apricot belongs to the rosaceae family and is considered as an economically important fruit among others. irregular bearing is a shortcoming in apricot production which is partly due to its limited ecological adaptation. the aim of this study was to investigate the effects of temperature prior to flowering stage on some characteristics as related to flowering organs. in two consecutive years, s...

Predicting Student Performance in Verbal Math Problems Based on Cognitive, Metacognitive, and Affective Factors F. Karimi, Ph.D. A.R. Moraadi, Ph.D. P. Kadivar, Ph.D. R. Kormi Noori, Ph.D. To determine the predictive role of metacognitive, cognitive, and affective factors in solving verbal math problems, a cluster sample of 450 junior high school  students was given ...

The introduction of new materials can significantly improve the performance existing dampers, but constitutive model is difficult to be obtained in a short time, which makes its numerical simulation difficult. Bouc–Wen–Baber–Noori (BWBN) well describe stress-strain relationship materials, and it helpful introduce into simulation. In this paper, high manganese steel material used fabricate buckl...

Hysteretic models with slip are frequently used to predict the non-linear behaviour of many structural systems, for example wood buildings and reinforced concrete structures. A model, called SL model, which can describe the pinching of most practical hysteresis loops perfectly was proposed by Baber and Noori. This model is characterised by control parameters that have to be identified from obse...
