WebThe term duplex wave describes propagation paths with a double reflection involving a reflecting base boundary and a near vertical feature. The purpose of our study was to examine the possibility of using duplex waves to directly image vertical features. Here, … WebSlight differences in the migrational behavior can produce mutation-specific band patterns. The method is quite popular in genetics for the analysis of extremely polymorphic genes. It is technically simple, although it is far more suitable for providing evidence of larger changes than for point mutations.

This kind of migration and diffraction imaging exploit "neighbouring " phenomena - reflection from a fracture plane ... Webhigher duplex fiber speeds by deploying other techniques such as wave division multiplexing. Designing fiber optic cabling for data centers requires a strategy to balance the cost/benefit of the opto-electronics against the investment choices for fiber optic cabling. One basic trade-off is a choice between parallel and duplex fiber links.
