This paper is based on the controversies which the existing empirical researches on the impact of the basic factors affecting energy efficiency, have in index selection and direction, using the method of meta-regression to analyze the related domestic empirical studies comprehensively. We conducted a study on the differences of research design, data characteristics, time span and the index sele...

The modeling and analysis of degradation data have been an active research area in reliability engineering for assessment system health management. As the sensor technology advances, multivariate sensory are commonly collected underlying process. However, most existing on requires a univariate index to be provided. Thus, constructing is fundamental step modeling. In this paper, we propose novel...
