Social influence has been a widely accepted phenomenon in social networks for decades. In this paper, we study influence from the perspective of structure, and focus on the simplest group structure — triad. We analyze two different genres of behavior: Retweeting on Weibo1 and Paying on CrossFire2. We have several intriguing observations from these two networks. First, different internal structures...
This paper proposes a practical and effective method base on weather patterns for producing 15-minutes short-term prediction of photovoltaic generation with a prediction horizon of 24 hours. Two different radiation prediction models are examined for two different weather patterns. In the clear sky model, the surface radiation is predicted by calculating the cutting plane instantaneous intensity of...
Based on the requirement of improvement of the mechanical equipment maintenance and support, and considering the actual demand prediction and decision-making problem of equipment maintenance and support, the stochastic service system theory was used in this paper. The basic principle, distribution rules, representation methods, main models and measurement indicators of the stochastic service system...
This article firstly presents an analysis and survey regarding the traditional evaluation and forecasting model on fuzzy time series. lt is pointed out that the maximum Subordination degree method and Subordination degree-Weighted average method is not suitable to attribute space usually, and a new evaluation model is proposed. The empirical study show that the new evaluation model is better able...
This paper proposes a robust model predictive control (MPC) scheme to asymptotically stabilize an uncertain linear plant with polytopic model uncertainty description. Quadratic robust stability constraints are explicitly imposed as contractive constraints on the predicted state at each sampling time. The feasibility of these constraints can be detected either off-line or at the first step of on-line...
