Frequent itemsets which are quite useful in many applications always suffer from their huge number and information redundancy. Frequent closed itemsets that provide a minimal and lossless presentation of all frequent itemsets are a solution to the problem. In past years, frequent closed itemsets mining (FCIM) has been extensively studied and many effective FCIM algorithms have been proposed. CHARM...
Since the highly conflicting evidence could not be combined effectively through D-S evidence theory, a novel D-S data fusion method based on evidence quality is introduced in this paper. The concrete algorithm for the reliability of observer and the measure of quality function value based on observer reliability are proposed. In the data fusion, adopting the measure of evidence quality, the collected...
Psychological contract received wide interest among researchers from different countries and became an ideal framework in the study of the employment relationship. In this study, we focused on the impact of organizational behavior on psychological contract breach in China. We conducted an in-depth questionnaire survey to 512 MBAs and senior managements in Zhejiang enterprises. By applying structural...
This paper presents a new method to select a segment-to-segment matching by analysing signature verification, accordingly curve segments used in signature verification and the regional feature contained in the curve segment are picked-up and the regional features are selected by ant colony optimization (ACO) algorithm and genetic algorithms(GAs). Namely, features selected are first encoded into chromosome,...
Second life is a popular Internet virtual system these days. This paper is to introduce the core features of second life and the libraries in it, hence further discuss the value and the service for libraries in second life.
A novel low-pass filter (LPF) with sharp cutoff frequency response and wide rejection bandwidth is proposed in this paper. The proposed LPF is composed of microstrip coupled-line hairpin unit, semicircle defected ground structures (S-DGS) and semicircle stepped-impedance shunt stubs (S-SISS). Sharp roll-off skirt and good out-of-band rejections are achieved as demonstrated in both simulation and experiment.
This paper introduced the domain of a sentence group. A domain is described with conceptual symbols in linguistic conceptual space. The domain of a sentence group can be extracted from words and their roles in the semantic structure of a sentence. Four kinds of relationships between the conceptual symbols of domains were discussed. These relationships are also helpful to confirm the domain of a sentence...
