Self-similarities in Hilbert Envelope Energy Regions on Motion Waveforms Application in Detecting Motion Irregularities in Video Frames
Abstract: This paper introduces self-similar Hilbert envelope energy regions that are commonly found in oscillating spectral curves. The time-varying amplitudes and peak value frequencies in typical spectral curves reflect the response of a system to external stimuli. A Hilbert envelope is a smooth curve connected between spectral curve peak values. Each peak value on an envelope curve at time identifies an envelope-bounded region with interior area (called Hilbert envelope energy region …

EGT Margin of A Jet Engine – Cause, Impact, Improvement & Simulation Theory
Abstract: When an engine runs, it produces heat and there is a range of temperature in the engine chamber. For Jet Engines, when it starts, temperature starts increasing within a range. At various durations of the engine run, there is some temperature. Higher the thrust, higher the heat temperature. This temperature is called Exhaust Gas Temperature (EGT). There is a maximum allowed gas temperature for each type of engine and the …
