A Survey on Fractal Antennas
Abstract: Modern communication systems demand antennas with (1) compact size, (2) low profile, and (3) multi or broadband characteristics without altering antenna properties moreover, if possible enhancement should obtain. “The Fractal Antenna” operates at all ideal characteristics. So the present paper considers different fractal geometries, and its operation as antenna

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 …
