Development of distributed computing systems (DCS) takes an important place in modern scientificand technical literature. Generally, only one the most significant features DCS is discussedin papers, for example, performance, reliability, fault tolerance, energy efficiency andscalability. In this paper authors attempt to overall consider problem design, based on theexample a multi-channel onboar...

Real-world stream data with skewed distributions raises unique challenges to distributed processing systems. Existing workload partitioning schemes usually use a “one size fits all” design, which leverages either shuffle grouping or key strategy for the workloads among multiple units, leading notable problems of unsatisfied system throughput and latency. In this article, we show that based resu...

Friction stir processing was applied for fabricating an aluminum alloy based hybrid nano composite reinforced with nano sized Al2O3 and micro sized graphite particles. A mixture of Al2O3 and graphite particles was packed into a groove with 1 mm width and 4.5 mm depth, which had been cut in 5083 aluminum plate of 10 mm thick. Packed groove was subjected to friction stir processing in order to im...
