This paper proposes a novel current/voltage sensor fault detection and isolation (FDI) method for wind energy conversion systems (WECSs) based on the power balance principle. The proposed method uses the sensor-measured signals to calculate the imbalanced power in the power converters of a WECS, which is then used as the indicator for sensor fault detection. The fault isolation process is started...
This paper presents a novel approach for performing intuitive 3D gesture-based interaction using depth data acquired by Kinect. Unlike current depth-based systems that focus only on classical gesture recognition problem, we also consider 3D gesture pose estimation for creating immersive gestural interaction. In this paper, we formulate gesture-based interaction system as a combination of two separate...
Currently, the most common way to control an electric wheelchair is to use joystick. However, there are some individuals unable to operate joystick-driven electric wheelchairs due to sever physical disabilities, like quadriplegia patients. This paper proposes a novel head pose estimation method to assist such patients. Head motion parameters are employed to control and drive an electric wheelchair...
Adsorption behavior of chitosan composite fly ash (CCF) in adsorption of reactive brilliant blue wastewater were investigated. CCF was characterized by means of SEM and FTIR. Results showed that particle size of CCF is about 2–15µm. The isothermal adsorption follows the isothermal adsorption model of Langmuir. Enthalpy change at adsorption tempertures in range of 288–318K is −21.97 kJ mol−1, which...
Draw bead geometry parameters have a significant effect to the quality of sheet metal forming. The application of response surface method (RSM), orthogonal experiment design method (OEDM) and dynamic explicit finite element method (FEM) in the optimum design (OD) for draw bead geometry parameters used in drawing procedure of cross member panel, a benchmark of Numisheet'2005, was discussed. The comparison...
The identification problem for circular drawbead geometric parameters was discussed. The application method of genetic algorithm and equivalent drawbead model on identification for circular drawbead geometric parameters from given drawbead restraining force was developed and programmed, in which equivalent drawbead model was used as forward solver and genetic algorithm was adopted to solve the inverse...
Dow Jones Cbn China 600 Inde is a measure of an indicator of the stock which China's domestic investors can invest in. Through the prediction of the Dow Jones Cbn China 600 Inde, we can predict the future development trend of China's Stock Market. In this paper, we established prediction models based on "most updated" GM(1,1) model and grey dynamic neutral network. The Dow Jones Cbn China...
Binary semantic relation extraction is particularly useful for various NLP and Web applications. Currently Web-based methods and Linguistic-based methods are two types of leading methods for semantic relation extraction task. With a novel view on integrating linguistic analysis on local text with Web frequent information, we propose a multi-view co-clustering approach for semantic relation extraction...
The V-detector generation algorithm is a kind of negative selection algorithm (NSA) inspired by biological immune system (BIS). In this paper, V-detector generation algorithm is simply introduced. The problem that V-detector generation algorithm can not meet the change of parameters in significant level is also pointed out. This problem will cause instable algorithm performance. In the meantime, it...
This paper describes the qualitative simulation modeling applied to a supply chain management. The main objective is to use complex system modeling methods to model the SCM (supply chain management) and then to determine the main parameters which have influence on the performance of the SCM. In this paper, the time series of the demand information from the customers will be analyzed and the forecasting...
