1 In this paper, we survey the relationship between the similarity measure and dissimilarity measure for fuzzy sets. First, we design a similarity measure using a distance measure for fuzzy sets and prove its usefulness. From this result, we assert that the similarity between two complementary fuzzy sets satisfies the fuzzy entropy definition. We also show(More)
In this paper, we present an algorithm for computing the number of points on the Jacobian varieties of one-dimensional family of genus 3 nonhyperelliptic curves over finite fields. We also provide the explicit formula of the characteristic polynomial of the Frobenius endomorphism of the Jacobian of C : y 3 = x 4 + a over a finite field Fp with p ≡ 1 (mod 3)(More)
Issues about privacy-preserving data mining have emerged globally, but still the main problem is that non-sensitive information or unclassified data, one is able to infer sensitive information that is not supposed to be disclosed. Based on our previous paper [1], we employ PRBAC for privacy preserving data publishing (PPDP). Using an extended role based(More)
With advances in sensor techniques, much research is focused on USN (Ubiquitous Sensor Network) computing services and context analysis service is an important field among them. However, sensor stream data, which is generated from sensors used in many USN domain applications, is too fast to control each of them and the volume is too huge to store the whole(More)
