Novel methods for improving compression efficiency by compressing and encoding images are proposed in this patent. The image to be compressed is partitioned into blocks, which will then be individually analyzed to determine suitability for discrete wavelet transform pre-processing. The blocks are al.....

An economical and versatile approach is developed to construct photonic structures using well-established solution-based deposition and post-deposition modification techniques. Without sophisticated and expensive vacuum equipment or control systems, such an approach can achieve elaborate periodic mi.....

Axial mode helix antennas are used as RFID base station antennas but the number of winding of helix antennas are at least 10, making them too high for use as base station antennas. To address the problem, an integrated wire elliptical helical antenna with novel cuboids dielectric resonator loading f.....
