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...
Based on the transportation mode of high-speed trains and mid-speed trains operating on the same line, considering the delay time of different level trains influence the total late time differently and setting the double control parameters, the mathematical model of the train traffic control is built. According to the theory of genetic algorithm, the sectionalized structural optimization for chromosome...
Based on the governing equation of seepage, we investigates the influence of consolidation stress on unsaturated seepage in soil slope, considering the relationships among stress and strain, saturated permeability coefficient and soil porosity, and combining the consolidation stress and Soil-water characteristic curve, put forward a numerical method which couples the unsaturated seepage and stress...
Website quality is crucial for acquiring user satisfaction and e-commerce website success. Based on TAM and information system success model, we analyze the effect of website quality on user satisfaction. Website quality includes three dimensions: system quality, information quality and service quality. These dimensions affect user satisfaction through perceived ease of use, perceived usefulness and...
Due to perceived high risk in the first transaction and Internet low switching cost, building consumer initial trust is crucial for online vendors. Extant research has often examined determinants of initial trust from the perspectives of TAM and trust transference, and seldom considered the initial trust building from dual-routes. Drawing on ELM, we analyzed the different effect of argument quality...
Mobile service providers often invest heavily on attracting new customers. If these new customers cannot be transformed into loyal ones, service providers will bear great loss. To improve user repurchase behavior, service providers can take measures to directly promote user repurchase on the one hand. On the other hand, they need to curb users' switching behavior. From these two perspectives, this...
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 hybrid power system with a PV energy conversion system is proposed with lead-acid batteries based long-term storage units and ultracapacitors based fast-dynamic storage units in a DC-coupled structure. It is necessary and important to manage the powers among those different power sources. A power management algorithm is proposed for this hybrid power system by taking into account the characteristics...
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:...
User acceptance of mobile service is the first step for enterprises to successfully implement mobile commerce. Extant research has tried to explain user acceptance of mobile commerce based on TAM and neglected the impact of usage cost, enjoyment and social evaluation on user behavior. Based on the theory of perceived value,this paper examines the impact of perceived value on user acceptance behavior...
