A new fast static security analysis algorithm, based on the interval analysis theory and probability theory, is proposed to improve the efficiency and accuracy of security analysis during power network interaction. In this paper, the characteristics of network interaction and uncertainty in the interaction process are illustrated firstly. After that the dimension reduction technique is employed in...
WAMS(Wide-area Measurement System) is one of the most potentially effective techniques to damp inter-area low frequency oscillations in power systems. This paper studies the data corruption phenomenon which is ubiquitous in WAMS and establishes the unified model of time-delay and data-loss. Then DTA(Damping Torque Analysis) index considering time-delay and data-loss is deduced based on the previous...
A novel type of plasmonic nanolaser based on coupled nanowires consisting of a gain material and a core/shell metal/dielectric nanowire is proposed. It shows the potential to enable deep-subwavelength lasing with low pump thresholds.
A novel type of coplanar plasmonic laser based on an edge-coupled hybrid plasmonic waveguide is proposed and analyzed theoretically. This structure enables the realization of an air gap between the nanowire and the metal layer that could facilitate enhanced field confinement. By simulating the modal properties and the lasing threshold under different geometric parameters, it is demonstrated that with...
A holey fiber design with a high index nanostructure that can achieve an effective mode area not in excess of 0.3 mum2 and a flat dispersion at the 1.55 mum band is proposed and studied.
User active knowledge contribution is crucial for virtual community development. Social cognitive theory (SCT) argues that individual behavior is influenced by both environment and personal cognition. Based on SCT, this paper analyzed the effect of trust as an environmental factor and self-efficacy, community-related outcome expectation and personal outcome expectation as personal cognitive factors...
A precondition for mobile commerce success is user acceptance. Based on UTAUT that explains user acceptance of information technology, and combined with a special characteristic of mobile technology: contextual offering, we examined the factors significantly affecting mobile commerce user acceptance. We employed questionnaire survey to collect 250 valid papers and analyzed data with SEM software:...
