Miniature solid state phase detector using MOSFETs is used in a phase lock loop with a sun-bit detector in an integrated data-link circuit. This replaces bulky transformer circuits. It uses an inverter amplifier, a modulator switch, and a buffer amplifier.
Metallic coating materials evaluated for use in transition joints for SNAP-8 transformer reactor assembly
Code transformation task for measuring performance of nonverbal mediation
High temperature cobalt iron alloy for square loop and power transformer applications
Hypersonic turbulent boundary layers transformation to incompressible form
Report applies transformation groups to the solution of systems of ordinary differential equations and partial differential equations. Lies theorem finds an integrating factor for appropriate invariance group or groups can be found and can be extended to partial differential equations.
