Preface

Abstract: We analyzed the attributes of software defects, and proposed a method of positive and negative association rules based on multiple minimum supports to research on software defects. The application in the software indicated that this method can discover rules of higher quality, fewer errors and conflicts without suffering from combinatorial explosion and missing some less-supported or recessiveness rules.

Abstract: The electronic transport properties are the basis for investigations on silicon carbide nanotube (SiCNT), which are suitable to develop novel nanometer electronic devices. The electronic transport properties of Single-Walled (8, 0) SiCNTs with antisite defects are investigated with the method combined Non-Equilibrium Green’s function with density functional theory. Results show that the similarity on electronic transport properties of the nanotube with different defects is high. Under a bias value greater than 1.0 V, a nearly exponential relationship between the bias and the current is achieved, which originates from more orbital participating in its transport properties caused by the increase of the bias.
