A potentially serious problem with current payment systems is that their underlying hard problems from number theory may be solved by either a quantum computer or unanticipated future advances in algorithms and hardware. A new quantum payment system is proposed in this paper. The suggested system makes use of fundamental principles of quantum mechanics to ensure the unconditional security witho...

The unified power quality conditioner (UPQC) is being used as a universal active power conditioning device to mitigate both current and voltage harmonics at a distribution side of power system network. This paper emphasis enhancement of power quality by using UPQC with fuzzy logic controller (FLC) and proportional-integral (PI) controller. The main purpose of the proposed (FLC) is capable of pr...

In the current information age, the dominant method for information search is by providing few keywords to a search engine. Keyword search is currently one of the most important operations in search engines and numerous other applications. In this paper we propose a new text indexing technique for improving the performance of keyword search. Our proposed technique not only speeds up searching o...
