Abstract Backward wave oscillators represent a class of tunable sources of electromagnetic radiation that do not require a resonant cavity to satisfy the oscillation condition.In the optical regime, the Backward Wave Optical Parametric Oscillator (BWOPO) relies on a a nonlinear interaction to provide the positive feedback required for oscillation,
It seems there is a scope to study how we can find the fuzzy reliability of two-stage weighted-k-out-n.This paper studies Regulators the fuzzy reliability of two-stage weighted-k-out-of-n model with components in common.Algorithms are developed to calculate the system fuzzy reliability, and generate the minimal cuts and minimal paths of two-stage w
The paper investigates the influence of structural components of a composite material on the strain values measured by using an embedded optical fiber with Bragg gratings.The effect of composite plies and intermediate epoxy layers on the Memory transfer of deformations from the measured object to the optical fiber was studied taking into account va
The hydrolate byproduct resulting from the industrial essential oil extraction of Spanish purple garlic has been studied Floor Mats against the root-knot nematode Meloidogyne javanica by in vitro and in vivo bioassays.The essential oil, the hydrolate and its organic fraction caused high mortality of juveniles, suppressed egg hatch, and reduced nema
Modern domestic and international standards, regulators of the aviation fuel industry, considering the negative impact of the presence of mechanical impurities and water in aviation fuel on the performance and life cycle of aircraft engines, Shirts fuel metering equipment, fuel systems of aircraft (A/C), as a threat factor for flight safety, impose
