This paper researches on the inherent characteristic of the fluctuant wind power and its propagation characteristic in a microgrid simulation system. First, the wind power data are non-stationary random signals due to the wind's inherent characteristic, and are hard to describe by function. The non-stationary wind power data are decomposed into the trend part and stationary part by the empirical mode decomposition method. The stationary part is then decomposed into different instantaneous frequency components by Hilbert transform. Second, a low voltage microgrid network is built on the PSCAD/EMTDC, and it is also connected to a medium voltage distribution network. All kinds of components are inputted into the simulation system as the port property of the wind power generation system. The voltage fluctuation of some important buses are inspected and compared when each wind power component is inputted. Last, according to the impact of each component the fragile bus and the key component are found. The fragile bus is an important factor when locating the wind power system, and the key component of the wind power can guide the optimal control strategy which suppresses the fluctuation of wind power, for instance, only considering the key component can be more economic when using energy storage system to suppress the fluctuation.

Identified charged pion, kaon, and proton spectra are used to explore the system size dependence of bulk freeze-out properties in Cu+Cu collisions at sNN=200 and 62.4 GeV. The data are studied with hydrodynamically motivated blast-wave and statistical model frameworks in order to characterize the freeze-out properties of the system. The dependence of freeze-out parameters on beam energy and collision centrality is discussed. Using the existing results from Au + Au and pp collisions, the dependence of freeze-out parameters on the system size is also explored. This multidimensional systematic study furthers our understanding of the QCD phase diagram revealing the importance of the initial geometrical overlap of the colliding ions. The analysis of Cu+Cu collisions expands the system size dependence studies from Au+Au data with detailed measurements in the smaller system. The systematic trends of the bulk freeze-out properties of charged particles is studied with respect to the total charged particle multiplicity at midrapidity, exploring the influence of initial state effects.

We present the measurement of nonphotonic electron production at high transverse momentum (pT>2.5 GeV/c) in p+p collisions at s=200 GeV using data recorded during 2005 and 2008 by the STAR experiment at the Relativistic Heavy Ion Collider (RHIC). The measured cross sections from the two runs are consistent with each other despite a large difference in photonic background levels due to different detector configurations. We compare the measured nonphotonic electron cross sections with previously published RHIC data and perturbative quantum chromodynamics calculations. Using the relative contributions of B and D mesons to nonphotonic electrons, we determine the integrated cross sections of electrons (e++e−2) at 3 GeV/c

The STAR Collaboration at the BNL Relativistic Heavy Ion Collider has measured two-pion correlation functions from p+p collisions at s=200 GeV. Spatial scales are extracted via a femtoscopic analysis of the correlations, though this analysis is complicated by the presence of strong nonfemtoscopic effects. Our results are put into the context of the world data set of femtoscopy in hadron-hadron collisions. We present the first direct comparison of femtoscopy in p+p and heavy ion collisions, under identical analysis and detector conditions.

Land Use / Cover Change (LUCC) is an essential component in the field of regional environmental monitoring and economic development analysis. Its motivation is to get an in-depth understanding of dynamic process, leading causes and evolution mechanism of regional land use change, which provide accurate information for land administration to develop local economic development planning and management. data analysis and processing plays a key role in LUCC. This paper summarizes four kinds of spatio-temporal analysis indexes, including magnitude, velocity, regional differences and inner conversion. Then Lijiang Region is taken as an example, and these four indexes are applied to analyze its land use change. Results reveal numerical and spatial difference in LUCC, and they are accorded with local actual conditions.

Linear discriminant analysis (LDA) is one of the most popular methods for feature extraction and dimensionality reduction, but it may encounter the so called small sample size (SSS) problem when applied to high dimensional data analysis such as face recognition. Many two-stage methods were proposed to solve this problem such as Fisherfaces, Direct LDA and Null space LDA, but they are suboptimal from the perspective of optimization. In this paper we propose a novel two-stage discriminant criterion named Range Space LDA, which projects all samples into the range space of between-class scatter matrix in the first stage and then performs traditional LDA. The effectiveness of our method is verified in the experiments on some benchmark face databases.

The centrality dependence of the charged-particle multiplicity density at midrapidity in Pb-Pb collisions at sNN=2.76 TeV is presented. The charged-particle density normalized per participating nucleon pair increases by about a factor of 2 from peripheral (70%–80%) to central (0%–5%) collisions. The centrality dependence is found to be similar to that observed at lower collision energies. The data are compared with models based on different mechanisms for particle production in nuclear collisions.

A finite element calculation model of corroded RC eccentric compressive members was build using finite element software ANSYS. The model considers the decline of mechanical properties and the effective section of a corroded steel bar, as well as the deterioration of bond character between corroded reinforcement and concrete. The reliability of the finite element model was evaluated by comparing the results of the finite element calculation with the data from experiments. Based on the finite element analysis results, the influence of corrosion degree, the diameter change of the longitudinal reinforcing bars and the spacing change of stirrups on the flexural stiffness were calculated and analyzed.
