    摘要: A method for forming a multi-component composite metallic tube, in particular, a bi-component metallic tube, comprises the steps of forming a coextrudable, multi-component billet including an inner component formed from a first metallic material, and an outer component formed from a second metallic material. Notably, explosive bonding is employed for bonding the first and second components to form a metallurgical bond at the interface thereof, thus forming the desired multi-component billet. The multi-component billet is subsequently heated, and coextruded to form a multi-component tubular structure, having a metallurgical bond at an interface between inner and outer layers of the composite metallic tube.

    摘要: General purpose parallel computer, latency reduction MIMD, with multiple processors, and multiple memory address spaces, wherein processors (SPU) are redundantly replicated on each memory (M) bus (C-BUS) and, formed/connected as either master-active or slave-active of the bus and to interface a suitable communication structure (A-S) for transferring among themselves the process context and the bus control, in such a way to execute in turn a unique migrant sequential process per bus (C-BUS), and wherein each processor is also directly and tightly coupled with devoted private buses (P-P) to one corresponding processor of another one bus (C-BUS) in a way to form, between distinct buses (C-BUS), biprocessor pairs (DPU) capable of allowing communication and synchronization of the parallel migrant processes.
