Simultaneous Multithreading Fau Tolerance Processor

Transient fault detection mechanism is added to simultaneous muhithreading architecture. By exploiting both ILP (Instruction l~evel Parallelism) and TLP (Thread Level Parallelism), Simultaneous Multithreading(SMT) Fault Tolerance Processor can be expected to achieve better tradeoff between performance and hardware cost than traditional Fault Tolerance Processors. Detailed simulations of 3 of SPEC95 benchmarks show that executing two redundant programs on the fault-tolerant microarchitecture takes only 40%-61% longer than running a single version of the program. The new instruction fetch algorithm enhances the performance by 0. 4%～1% to most of the benchmarks we choose randomly.     

Initiating, growing and cracking of hydrogen blisters

The growing process of a hydrogen blister in a wheel steel was observed in situ with an optical microscope, and the fracture surfaces formed from broken blisters on a wheel steel and bulk metallic glass were investigated. The initiating, growing, cracking and breaking of hydrogen blisters are as follows. Supersaturated vacancies can increase greatly during charging and gather together into a vacancy cluster （small cavity）. Hydrogen atoms become hydrogen molecules in the vacancy cluster and hydrogen molecules can stabilize the vacancy cluster. The small cavity becomes the nucleus of hydrogen blister. The blister will grow with entering of vacancies and hydrogen atoms. With increasing hydrogen pressure, plastic deformation occurs first, the hydrogen blister near the surface extrudes, and then cracks initiate along the wall of the blister with further increasing hydrogen pressure. A cracked blister can grow further through propagating of cracks until it breaks.

Synthesis, characterization and properties of diamidodisilanes and azocyclosilane

Organosilicon compounds have been widely researched and have the maximum species besides hydrocarbons. In the progress of the research work, many scientists pay attention to the organic silicon compounds that have vari-ety reactive functional groups[1,2]. The difunctional disi-lanes are very active; they could react with not only the compounds containing reactive hydrogen atoms, but also the reactive polymers. Therefore, the disilanes with di-functional groups could be used as disilane substit…
