This paper proposes a notion of indicative concepts in a transaction database, presents a branch-and-bound optimization algorithm to find a top-N indicative concepts in a space of many local minimum solutions. An indicative concept consists of several general items as primitive events, but has a very small degree of correlation in spite of the generality of component items. We regard those indicative...
Within a carbon constrained world, the proportion of generation from nonconventional renewable energy sources in the generation mix of power systems, is expected to increase substantially. The generation from renewable sources, connected to power networks mostly at distribution level, will change the traditional power flow patterns and produce adverse power fluctuations due to its random nature. Although...
Within the carbon constrained world, virtually unrestricted integration of renewable energy sources into power networks is expected to become common in practice, making power systems to be more ubiquitous[1] in nature, structurally and operationally. Consequently, handling the intermittent and random behavior of renewable generation, thus Load Frequency Control (LFC), would become one of the major...
For RFID tags to proliferate in our day to day life, they will have to offer practical, low cost and secured mechanisms for tag authentication which has been in the midst of researcher's interest for almost a decade. One extension of RFID authentication is RFID tag searching, which has not been given much attention so far. But we firmly believe that in near future tag searching will be a significant...
