To assimilate satellite-based passive microwave observation over heavy clouds and precipitation into numerical weather prediction (NWP) systems and thus to improve the performance of it has become an intensely studied topic. These attempts rely on the development of a radiative transfer (RT) model that accounts for particle scattering and accurately simulates the observation process at an acceptable...
To hit incoming balls back to a desired position, it is a key factor for table tennis robot to get racket parameters accurately. For modeling the stroke process, a novel model is built based on multiple neural networks. The input data for neural networks are the ball velocity differences during the stroke, and racket parameters are the output data. To reduce the influences from the invalid data, a...
In recent years, a variety of privacy events emerges and bring huge losses. With the in-depth application of data mining, big data, cloud computing and other technology, privacy protection issue becomes more and more challenging. Therefore, we propose a privacy protection mechanism for sensitive group information. A reasonable counterfeit data set is constructed based on cloud model for sensitive...
Anomaly detection in streaming data is of high interest in numerous application domains. In this paper, we propose a novel one-class semi-supervised algorithm to detect anomalies in streaming data. Underlying the algorithm is a fast and accurate density estimator implemented by multiple fully randomized space trees (RS-Trees), named RS-Forest. The piecewise constant density estimate of each RS-tree...
Compared to constraint-based causal discovery, causal discovery based on functional causal models is able to identify the whole causal model under appropriate assumptions. Functional causal models represent the effect as a function of the direct causes together with an independent noise term. Examples include the linear non-Gaussian a cyclic model (LiNGAM), nonlinear additive noise model, and post-nonlinear...
In the paper, the principle of speed governor of synchronous machine is discussed firstly. Based on this, mathematical models of the speed governors of BPA and PSS/E are compared to find the corresponding relationship of the speed governor models between BPA and PSS/E. The corresponding models have been validated by simulation of a single machine infinite bus system and the quantitative analysis of...
This paper studied the needing laws of photosynthetically active radiation through the dry matter accumulation, and a simulation model of peanut dry matter accumulation has been established based on the field experimental data in 2007 and 2008. Then the yield composition simulation model was established according this. The validation with different data sets showed that this model had a good predictability...
