the last decades, the nonholonomic control systems have attracted lots of interest, but little has been done in the nonholonomic control systems with rheonomous affine kinematic model constraints. In this paper, we structure the nonlinear control systems of the nonholonomic control systems with rheonomous affine kinematic model constraints for the first time, and propose an adaptive control system for the tracking control of the nonholonomic control systems with rheonomous affine kinematic model constraints. Finally, a numerical example is provided to demonstrate the potential and effectiveness of the method. © Sila Science. All Rights Reserved.

As a clean energy, wind energy plays a more and more important role in the energy structure. Each uncertainty, intermittent and wind farm and other aspects of the wind to make use of wind energy difficulties. In order to solve these difficulties and to study the wind power laws, and better utilization of wind energy. we establish a new CFGM(1,1) model by combining the Linear Regression Model with FGM(1,1) appropriately in this paper. By means of CFGM(1,1), we have a higher prediction accuracy. © Sila Science. All Rights Reserved.

Because of the important technological and economic impacts of wind speed on wind power generation and the increasing as a renewable energy source in many countries of wind power, providing accurate wind speed prediction algorithms has become increasingly significant to the planning of wind speed plants, the scheduling dispatchable generation and tariffs in the day-ahead electricity market and the operation of power systems. In this paper, a strategy, which adopts ARFIMA-EGARCH model is presented for wind speed forecasting. The results show that ARFIMAEGARCH model, which combines both the long memory time series and the conditional heteroscedastic processes, possesses higher accuracy than the classical approach towards wind forecasting. © 2013 Trade Science Inc. - INDIA.

The mechanism of the cycloaddition reaction between the interstellar molecules ketenimine and HCN was investigated employing the second-order Møller-Plesset perturbation theory (MP2) method in order to understand better the reactivity of the nitrogenous cumulene ketenimine with the carbon-nitrogen triple bond compound HCN. Geometry optimizations and vibrational analyses were performed for the stationary points on the potential energy surfaces of the system. The calculated results showed that five-membered cyclic carbene intermediates could be produced through pericyclic reaction processes between ketenimine and HCN. Through subsequent H-transfer processes, the carbene intermediates could isomerize to pyrazole and imidazole compounds. The present study is helpful in the understanding of the formation of prebiotic species in interstellar space.

Pentadiagonal Toeplitz systems of linear equations arise in many application areas and have been well studied over the past years, the invertibility of nonsingular pentadiagonal Toeplitz matrices has been quitely investigated in different fields of applied linear algebra. In this study, we provide a necessary and sufficient condition on which pentadiagonal Toeplitz matrix, present an algorithm for calculating the determinant of a pentadiagonal Toeplitz matrix and propose a fast algorithm for computing the inverse of a pentadiagonal Toeplitz matrix. © 2013 Asian Network for Scientific Information.

In this study, we establish a new MSTV-EGARCH model to study the wind power laws. By using the new model, we study the probability distribution function of wind power Variations and propose a root transformation method. The probability distribution of wind power can be transformed into a normal distribution. © 2013 Asian Network for Scientific Information.

Equipping steel tower atop building structural system at the top of high-rise buildings is applied increasingly. However, the earthquake disasters indicate that under seismic effect, the tower on the roof reacts strongly to the earthquake, and the gazebo is damaged greatly under the condition that major structure has no earthquake damage. Based on analyzing the characteristics and application methods of ETABS software, for engineering projects, the paper uses ETABS software and simplified calculation method to calculate and make comparison analysis on steel tower atop building structure. The analysis results indicate that the method established in the paper has higher accuracy, which can meet the engineering requirements. © (2014) Trans Tech Publications, Switzerland.

Higher gear-grinding accuracy can be obtained by using a flat-faced grinding wheel (FGW) and a generating method. However, the phenomenon of interfering with the adjacent tooth will happen when an unsuitable outer-edge width of the FGW is dressed. In order to optimise the shape of the FGW and further improve its rigidity and grinding accuracy, studies on the relative motion trajectory of the FGW, the correlations of the maximum outer-edge width (wmax) with the head frame setting angle (HSA, αy) and the adjustment quantity (E) in the feed direction were conducted. Finally a motion simulation and a grinding experiment verified the reasonability of the mathematical model and several improved measures to achieve interference free and rigid gear grinding were obtained. The results have important significances on formulation of scientific ultra-precision gear-grinding processes. Copyright © 2015 Inderscience Enterprises Ltd.

In this paper, we design a frame to automatically select CPU or GPU environment and establish four general parallel foundation libraries. First, the system general foundation library and mathematical foundation library are built on basis of the research on GPU parallel characteristics, CUDA programming technology and the serial algorithm of forward and preserved amplitude evaluation. Then, according to these two support libraries, we establish the forward general foundation library and preserved amplitude evaluation general foundation library, following several optimization strategies and criterions. Finally, accuracy and time experiments are taken to evaluate the two types of general parallel foundation libraries. It is showed the speedup has reached more than 10 times under the same accuracy. © 2016 IEEE.
