In this study, a series of laboratory tests were performed on 25 water samples obtained from the high‐altitude glacier‐fed water resources of Gilgit‐Baltistan Pakistan. The variations in the measured physico‐chemical parameters were found as follows: conductivity 62–989 (µS/cm), turbidity 0.94–10.86 (NTU), pH 6–8.4, TDS 40–830 (mg/L), hardness 30–305 (mg/L), Ca2+ 35–135 (mg/L), K+ 2–12.2 (mg/L), Mg...
In this paper, we propose an enhanced jk-nearest neighbor (jk-NN) algorithm for online signature verification. The effect of its main parameters is evaluated and used to build an optimized system. The results show that the jk-NN classifier improves the verification accuracy by 0.73–10% as compared to a traditional one-class k-NN classifier. The algorithm achieved reasonable accuracy for different...
