The purpose of this study paper is to examine the potential for increasing efficiency solar water heaters by using novel design ideas. A qualitative examination previously published material combined with development a computer-aided (CAD) model heater SolidWorks as part research project, which uses mixed-methods approach. draws attention relevance factors, materials, and combinations in optimi...

This paper presented a new structure for the CMOS power amplifiers as more effective trend to amplify radio frequency (RF) signals compared polar PA's by using envelope removal and restoration (EER) technique. Polar PA offers high-efficiency RF-modulated linear signal amplification. However, these need high uniformity between amplitude phase of modulated signals. The last translates promptly in...

In this paper, we propose a new algorithm, which utilizes the enhancement layer prediction to further improve the coding efficiency of current Fine Granularity Scalability (FGS) defined in MPEG-4. The proposed algorithm adaptively uses (1) the previously reconstructed enhancement layer macroblock after motion compensation along with (2) current reconstructed base layer macroblock and (3) the co...
