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...

Low precision arithmetic, in particular half (16-bit) floating point is now available commercial hardware. Using lower can offer significant savings computation and communication costs with proportional energy. Motivated by this, there has been a renewed interest mixed iterative refinement schemes for solving linear systems A x = b , new variants of GMRES-based have developed. Each variant give...

Design and manufacturing technology of high pressure multistage pumps which are commonly utilized in oil and gas industries, used to be imported from foreign companies. Due to international sanctions against I. R. Iran, it started to be designed and launched domestically. Nowadays all production lines including design, manufacturing and testing of these pumps have been performed by Iranian expe...

Depth filters used in multistage filter systems adeptly clean the intake air of gas turbines, preventing damage and increasing performance. However, estimation their service life is based on empirical data and/or standardized testing procedures, e.g., ISO 16890. By applying synthetic test dusts at constant reference humidity, these procedures do not reflect application-typical loading condition...

This research aims to examine the effect of some social and cultural factors (identity, self-esteem, religious commitments and normative pressure) on generation gap and younger people's compatibility with their parents. In terms of research methodology, this is a cross-sectional study and regarding data collection method, it has drawn upon a questionnaire. The statistical population includes th...
