This masterbatch material blender incorporates a rotary conveyor having openings therein that receive and retain predetermined amounts of virgin plastic material and color concentrate in one position of movement of the conveyor and discharge same to the extruder in yet another position of movement thereof. Furthermore, such conveyor is adapted to control yet another reciprocable metering and transfer mechanism that similarly controls the addition of reprocessed material to the batch by way of the same measuring and transferring device.

The flexibility of VoIP in general and of Voice Over Internet in particular

Fir s t, we dis cus s the meaning of context in computing. Second, the data s our ces compos ing the context ar e l is ted and defined. A definition of the meaning of Context Awar e s er vice is al s o pr ovided. Our des ign is bas ed on thes e definitions , and tar geted to pr ovide Context-Awar e s er vices to mobil e us er s. The key-featur e of the ar chitectur e is the expl icit or ientation towar d wor king in a condition wher e dir ect knowl edge of the us er s tate is minimal. I ts power r es ides in the capabil ity to infer the us er context fr om indir ect infor mation. This featur e is cal l ed Context-bas ed Content Engine (CCE) and is des igned to eas e its integr ation with exis ting s y s tems s uch as a ty pical tel ecom oper ator por tal. Our s er vice or iented des ign coul d be impl emented by s ever al pr ogr amming fr amewor k.

In 2006 the UDDI cloud, a registries federation managed by IBM, HP, Microsoft and SAP, was shut down with the end of the UDDI business registry (UBR) project. UDDI is still widely adopted for private registries. Isolated public registries are quite rare and an UDDI coordination mechanism is still missing. In

A quantitative study of the Linux kernel [1] responsiveness to hardware interrupts has shown a huge variance in experimental results, however, we argue that a careful selection of the modules inserted in the kernel can greatly reduce this variance and produce a much more predictable system. In this paper, we focus on one of the major sources of unresponsiveness in the kernel, namely the presence of nonpreemptible code sections, and we quantify its effects with a series of micro-benchmarks. Our extensive set of experiments allowed us to identify which Linux kernel’s modules can cause erratic behavior with respect to the responsiveness of the Linux kernel to hardware interrupts. 1

The typical environment required by Grid computing is complex, heterogeneous, and highly dynamic. The autonomous and flexible behavior provided by software agents meets various Grid requirements. In this paper we present the design and the implementation of a Grid architecture built over an agent based framework called AgentService. In this work we highlight the advantages in using the services of an agent oriented framework to develop a Grid application.
