The current study examined on-line behavior recategorization as a mechanism underlying corrections for contextual influences in dispositional inferences. After watching an initial comparison video that portrayed either a successful or unsuccessful performance on a spatial ability task, cognitive load and no load participants watched and made real-time ratings of a target performance. The compar...

The short-term load forecasting is an important method for security dispatching and economical operation in electric power system, and its prediction accuracy directly affects the operating reliability of the electric system. So the global optimization ability of particle swarm optimization (PSO) algorithm and classification prediction ability of support vector machine (SVM) are combined in ord...

in the current engineering practices, buildings are commonly designed for an effective lifetime of 50 years. this lifetime can increase the cost of buildings with short lifetimes and can reduce the safety level of buildings with large lifetimes. in this paper, a “service-life factor” has been defined. applying this factor into the nominal values of live, earthquake, wind, and snow loads, the ef...

Multiple voltage conversion ratio (VCR) recursive switched-capacitor (SC) dc–dc converters, based on several basic 2:1 are widely used for on-chip power supplies due to their flexible VCRs higher energy efficiency. However, conventional multiple VCR SC converters usually have one or more unused some VCRs, which results in lower density and chip area wastage. This article presents a new converte...
