An accurate and highly-efficient analysis approach is crucial for a designer to evaluate the performance of on-chip networks. To this end, the novel M/G/1/N queuing models that capture various blocking phenomenon of the wormhole switching router are presented to compute the average waiting time accurately. With the M/G/1/N queuing models, this paper then presents the performance analysis algorithm to estimate some key metrics in terms of packet latency, buffer utilization, etc. The comparisons with SystemC simulated results show that the proposed approach with mean errors of 6.9% and 7.8% achieves the speedups of 117 and 101 for single-channel and multi-channel routers respectively. In our design methodology, this approach can direct NoC synthesis process effectively and then can be applied to multi-objective optimizations conveniently to find the best mappings.

In the present work, the TIPS behavior of isotactic polypropylene(iP P)/di-n-butyl phthalate(DBP)/dioctyl phthalate(DOP)/nano-SiO_2 system and the competition relation between liquid–liquid phase separation and polymer crystallization are successfully adjusted by adding nano-SiO_2. The liquid–liquid phase separation temperature of the system increases with increasing nano-SiO_2 content. Besides, iP P crystallization temperature is also changed after adding nano-SiO_2. IPP/nano-SiO_2 blend hollow fiber microporous membrane is prepared via TIPS method. SEM photos show that the membrane exhibits mixed morphology combining cellular structure relating to liquid–liquid phase separation and branch structure originating from polymer crystallization. The relative weight of cellular structure first decreases and then increases with the increase of nano-SiO_2 content. Furthermore, porosity, connectivity among pores and pure water flux of the membrane first increase and then decrease with increasing nano-SiO_2 content. However, mechanical performance of the membrane is improved at all times with increasing nano-SiO_2 content.

The mixed mode Ⅰ/Ⅱ SCC behavior of X-70 pipeline steel in the Xinjiang soil solution was investigated using single edge-notched specimens loaded in anti-symmetric and symmetric four-point bending configurations in laboratory. The results show that a maximum tensile stress criterion provides a good description for the mixed mode Ⅰ/Ⅱ SCC of X-70 pipeline steel in the near neutral pH solution, and the mixed mode TGSCC crack growth rate is larger than that of the mode Ⅰ TGSCC. The magnitude increase of the crack growth rate decreases with the increase of the mode Ⅱ loading.
