this study was an attempt to investigate iranian and spanish intermediate nonnative english learners’ request strategies to their faculty. to this aim, 74 (50 iranian and 24 spanish) nonnative english intermediate learners participated in this study. a discourse completion test (dct) was used to elicit the request strategies used by the participants. the findings suggested the participants empl...

Background and Objectives: A blood distribution network orchestrates distribution of safe blood products to hospitals. Blood shortage and blood wastage are two important factors which may affect efficiency of blood distribution network. Service delivery time is another factor that refers to the time interval between blood request by a hospital and transfusing it to the patient....

One of the major challenges of cloud computing is the management of request-response coupling and optimal allocation strategies of computational resources for the various types of service requests. In the normal situations the intelligence required to classify the nature and order of the request using standard methods is insufficient because the arrival of request is at a random fashion and it ...

This paper presents speculative TCP connection admission, a mechanism for improving sub-optimal request distribution decisions in cluster-based servers. Overloaded server nodes in the cluster speculatively accept incoming requests only to offload them to less-loaded nodes. Speculative admission uses connection endpoint migration, a technique that allows server-side connection endpoints to be ar...
