the present work reports and discusses the results of a 3d simulation of the injection molding process of a rubber compound that includes the mold flling stage and  material curing, using the computer code is developed in “udf” part of the fluent 6.3 cae software. the data obtained from a rheometer (mdr 2000) is used to characterize the rubber material in order to fnd the cure model parameters ...

In practice, manufacturing systems are never perfect and may have low quality outputs. Therefore, different decisions such as reprocessing, sale at lower prices or diminishing are made according to industry and market. This paper investigates the importance of supply chain coordination through developing two models in centralized decision-making for an imperfect quality manufacturing system wit...

The production of seed by both selfing and outcrossing, or mixed mating, may be selected for under conditions of variable pollinator availability. Seed production was examined following experimental manipulations of perfect and pistillate flowers of the gynomonoecious plant Silene noctiflora. Style excision experiments in a greenhouse demonstrated that autonomous selfing occurs in the perfect f...

Maze is a place that has many paths with tortuous are misleading and full of dead ends can be viewed as grid graph. A non-perfect maze cycle. This research produces an algorithm form size m×n which two types bias. The first bias the composition percentage horizontal vertical partitions. second number cycles. created in this study was generated by modifying Prim’s use Fisher-Yates used random se...

A graph is strongly perfect if every induced subgraph H has a stable set that meets nonempty maximal clique of . The characterization graphs by forbidden subgraphs not known. Here we provide several new minimal non-strongly-perfect graphs.
