    An option is the right, not the obligation, to buy or sell an underlying asset at a later date but by fixing the price of the asset now. There are European and American styled options. European styled options can be priced using the Black-Scholes equations but American options are more complex and valuable due to the second random process they introduce. Multi-layer perceptrons and support vector ... View full abstract»

  • Fuzzy logic based speed control and slip compensation for rotor time constant variations in a field-oriented induction motor drive

    Publication Year: 2005, Page(s):57 - 62
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (290 KB) | HTML iconHTML

    Indirect field oriented (IFO) induction motor drives can provide fast dynamic torque response and track rapid changes in reference speed and load torques. However the decoupled control of torque and flux is affected due to variations in the rotor electrical time constant. As a result, the drive performance is seriously degraded, unless some form of adaptation is employed. This paper presents an IF... View full abstract»

    One of the tasks of data mining is classification, which provides a mapping from attributes (observations) to pre-specified classes. Classification models are built by using underlying data. In principle, the models built with more data yield better results (are more accurate). However, the relationship between the available data and the performance is not well understood. How much data to use, or... View full abstract»
