Conventionally, frequency tuning is achieved by changing the capacitance of a tank using varactor. However, it is more power efficient to minimize the capacitance of the tank and adjust the inductance for frequency variation. Therefore, the need for a variable inductor arises.A novel integrated vari.....

This is about a new scheme for driving reflective bistable cholesteric displays (BCDs). It relies on fast switching from the planar state to the focal conic (FC) state, the two stable states in BCDs. The new scheme allows BCDs be driven using simpler electrical wave forms, and also making line add.....

Color liquid crystal displays (LCD) are usually made by putting color filters onto the individual pixels. These color filters are resins with color pigments. Full color displays can be made by a combination of the red, green and blue primary colors. This coloring scheme is the predominant technology.....

Almost all soil slopes on land are initially unsaturated in nature. In order to determine the factor of safety of unsaturated slopes accurately, it is essential to calculate transient seepage and hence pore water pressures in the soil. To do so, one has to measure the so-called soil-water characteri.....
