In recent years the demand for small cellular handsets has grown substantially and the need for still smaller handsets continues to increase. Planer inverted-F antenna (PIFA) designs have received attention since they are compact. Although smaller sizes PIFA are needed, the design of compact antenna.....

Sulfur dioxide is one of the major components of acid rain emitted into the atmosphere resulting from fuel combustion and ore roasting process. The need for sulfur dioxide removal has been demonstrated, but the high cost of existing processes has prevented the wide application of sulfur dioxide remo.....

The alignment behavior of the liquid crystal layer of a liquid crystal display (LCD) determines most of its optical properties. The alignment direction and pretilt angles are determined by the alignment layers in contact with the liquid crystal layer itself and cannot be varied. Some traditional way.....

Cyclin-dependent kinases (Cdks) are key regulatory enzymes in the eukaryotic cell cycle. The activation of a Cdk depends on its association with its specific cyclin partner. The activity of these enzymes is further regulated by an intricate system of protein-protein interactions and phosphorylation......

Low-dropout regulator is a commonly used component in the power management integrated circuits for portable electronic devices. Conventionally, the stability of the regulator was achieved by frequency compensation such as dominant-pole compensation and pole-zero cancellation. However, this limits th.....
