In this work, we demonstrate examples about uses of practical image processing techniques over a new interpretation of power quality event data. Power quality event data are 1D da...
A novel and highly efficient algorithm of multiplicarionfree binary arithmetic coding is proposed. Our proposed method relies on simple table lookupsfor performing the computation...
With recent advances in temporal and spatiotemporal databases, user demands are becoming more complex. As a result, simple queries are replaced by complex multitemporal query scen...
