energy, due to its increasing usage in various broad areas has been maintained as a vital factor in economic growth and development of societies. meanwhile, natural gas is considered as one of the most important energy sources. therefore, the efficiency and the productivity of the gas companies are crucial to be assessed. numerous examples from industrial multistage processes including internal...

The history of technological developments affects the way we can provide services to customers quickly. One methods industrial Control Systems is statistical process control method (SPC) for short-term production. This review aims explain some advantages SPC method, namely in terms monitoring multistage processes and fault diagnosis has become a necessity. by Entering control. hybrid approaches...

The choice of an interconnection network for a parallel computer depends on a large number of performance factors which are very often application dependent. We propose a performance evaluation and a comparison methodology. This methodology is applied to a recently introduced class of interconnection networks (Multistage Chordal Ring Based multistage interconnection network). These networks are...

In this work we provide equations to precisely calculate the asymptotic weighting of multistage detectors satisfying the individually and jointly LMMSE criteria in the projection subspace for scenarios with unequal powers. Additionally, a general expression of the SINR achievable at the filter output as system size grows large is derived. Such equation can be applied to any multistage detector....

All-optical multistage interconnection networks are desirable for overcoming the limitations of optical signal regeneration in switching systems. We present a new implementation of the perfect-shuffle interconnection pattern that is coupled with an all-optical switching element, forming a complete stage of a multistage network. Switching is performed with birefringent calcite crystals and a fer...

Numerous combinatorial optimization problems (knapsack, maximum-weight matching, etc.) can be expressed as subset maximization problems: One is given a ground set $$N=\{1,\dots ,n\}$$ , collection $$\mathcal {F}\subseteq 2^N$$ of subsets thereof such that $$\emptyset \in \mathcal {F}$$ and an objective (profit) function $$p:\mathcal {F}\rightarrow \mathbb {R}_+$$ . The task to choose $$S\in max...
