IMPROVING THE CIRCUITRY OF HIGH-PRECISION HIGH-SPEED ACOUSTO-OPTIC LASER INTERFEROMETERS OF DISPLACEMENTS WITH FREQUENCY MATCHING OF COMPONENT BLOCKS AND DOUBLE HETERODYNING AT PHOTOTRANSFORMATION STAGE

The article discusses the development of the circuitry of acousto-optic (AO) laser displacement interferometers (LDI) and the values of resolution and speed of controlled displacements achieved by them.The issues of frequency matching of blocks of AO LDI are discussed: AO modulator, photodetector device (FDD) and frequency generator.The features of

Gas condensate is one of the most different fluids in reservoir simulation due to retrograde condensation in case of pressure reduction.In this kind of fluids, two phenomena named negative inertia and positive coupling, become significant in the high velocity zone around the wellbore.In Floor Mirrors this study, a modified black oil simulator is de

Abstract Background To compare two approaches to Ingredient Scoops the statistical analysis of the relationship between the baseline incidence of adverse events and the effect of medical emergency teams (METs).Methods Using data from a cluster randomized controlled trial (the MERIT study), we analysed the relationship between the baseline incidence

The Julian and Tuvalian lithologic column in the Oslica area starts with dolomitic breccias with limonitic groundmass and with a bauxite giving evidence of areal expose on the boundary between Cordevolian and Julian.Afterwards, precepitation of carbonate rocks followed.In the lithological Sticker interval where the limestone breccias predominate, o
