Acoustic control of mouse pointer. This paper describes the design and implementation of a system for controlling mouse pointer using nonverbal sounds such as whistling and humming. Two control modes have been implemented—an orthogonal mode (where the pointer moves with variable speed either horizon[r]

The simulation of power transformer models is
important when analyzing the dynamic behavior of power
systems, in particular, when considering voltage magnitude or
phase regulation controls. This paper reports results of

Large quantities of oil usually remain in oil reservoirs after conventional water floods. A significant part of this remaining oil can still be economically recovered by Water AlternatingGas (WAG) injection. WAG injection involves drainage and imbibition processes taking place sequentially, hence th[r]
