This paper describes two adaptive algorithms for dead reckoning in Distributed Interactive Simulation (DIS). The first algorithm is based on the control mechanism of adaptive adjustment of threshold level and the second on automatic selection of extrapolation equation. Since a fixed threshold cannot adequately handle the dynamic relationships between moving entities, a multi-level threshold sch...

An adaptive threshold computation method for pilot symbol assisted iterative channel estimation in coded OFDM systems is considered. The proposed threshold computation method is based on calculating a particular threshold for each data packet in order to select the reliable decoder output symbols to improve the system bit error rate performance. The adaptive threshold computation approach utili...

The enhanced abilities of online retailers to learn about their customers’ shopping behavior have increased fears of dynamic pricing, a practice in which a seller sets prices based on the estimated buyer’s willingness-to-pay. However, among online retailers, a deviation from a one-price-for-all policy is the exception. When price discrimination is observed, it is often in the context of custome...

This paper presents an algorithm for adaptive determination of the dead timeduring transient arcing faults and blocking automatic reclosing during permanent faults onoverhead transmission lines. The discrimination between transient and permanent faults ismade by the zero sequence voltage measured at the relay point. If the fault is recognised asan arcing one, then the third harmonic of the zero...

In this paper we examine a technique to improve the performance of serial, matched-filter acquisition in directsequence spread-spectrum packet radio communications. Each packet transmission includes an acquisition preamble, and the preamble sequence is changed at the boundaries of predefined time epochs based on a pseudorandom sequence generator. The acquisition algorithm considered in this pap...
