The study is focused on the development of an automation platform performing data mining works on telemetry database for computer systems. Very common computer systems encounter failures in an unexpected manor. It is therefore valuable to have prognostics task for computer systems to minimize the situation of unexpected system failure. Data acquisition schemes employing telemetry techniques are considered...
This paper proposes a methodology that incorporates the process of attribute reduction in rough sets into crossover in genetic algorithms (GAs). We develop two algorithms on the basis of the methodology. The first one selects the crossover points either by attribute reduction or randomly; the second one selects the points only by attribute reduction and no crossover otherwise. We study 0/1 knapsack...
For each positive integer n, let Tn be a random rooted full binary tree having 2n-1 vertices. We can view H(Tn), the entropy of Tn, as a measure of the structural complexity of tree Tn in the sense that approximately H(Tn) bits suffice to construct Tn. We analyze some random binary tree sequences (Tn : n = 1,2...) for which the normalized entropies H(Tn)/n converge to a limit as n rarr infin, as well...
Many studies have explored the use of tactile cues, however they were confined to the unilateral display device. Although lots of bilateral haptic devices have been developed to provide a guiding force on an input handle, however, a vibrotactile stimuli has not been tried to present directional information on the handle. This research introduces an attempt to combine a tactile display with an input...
For many real time information fusion systems, one way to reduce the computational complexity is to establish safe decision threshold, and only those above the safe thresholds are considered in decision making. Pignistic probability transform is a useful tool for decision making by mapping belief functions to probabilities to improve decision credibility and reduce computational complexity as well...
We demonstrate a novel technique for generation and transmission of IR-UWB signals over 100 metres 50-mum core GI-POF. IR-UWB pulses are made by linearly combining two 3rd-order derivatives of Gaussian pulses with different pulse-shaping factors.
Two similarity measures between strings are proposed. This correspondence also describes an experiment performed to illustrate the inadequacy of a commonly used measure.
