Color segmentation plays an important role as a primary process in the vision system of the robot soccer, since color is an effective and robust visual cue in the complex environment. However, color segmentation suffers natural variations in light and shadows as well as the limitation of calculation due to the real-time robot system. A color transformation is assumed to increase separability among...
Due to the complexity of the power plant production environment, it brings some difficulties to troubleshooting of turbine generator. Although the approach based on neural network has been widely used in fault diagnosis of equipment, the result of fault diagnosis, which is given by the single neural network, is often not ready to determine the fault type for turbine generator. In response to this...
This paper is concerned with robust fault detection problem of nonlinear uncertain networked control systems (NCSs). Two irrelevant Markov chains are introduced to describe Markov data transmission pattern in both from sensors to controller (S/C) part and from controller to actuators (C/A) part, then a Markovian jump system model is established. By employing mode-dependent fault detection filter as...
In terms of energy consumption, the environment surrounding the manufacturing industries has become considerably strict. As a framework containing many production scheduling problems in manufacturing industries, a great deal of researches on the resource-constrained project scheduling problem (RCPSP) has been performed. We have proposed a RCPSP formulation called RCPSP/πRC, which can deal with realistic...

This paper takes the excellent Function Point Analysis (PFA) method as the prototype. The development circumstance combines with Object-Oriented (OO) method. In the experiment of the implement section, the Unified Modeling Language (UML), which can integrate with class diagram and FPA, is chosen as a method. As a result, the proposed method for the effect of estimating function points (FP) has been...
Intelligent Data Analysis (IDA) is one of the most important approaches in the field of data mining, which attracts great concerns from the researchers. Based on the basic principles of IDA and the features of datasets that IDA handles, the development of IDA is briefly summarized from three aspects, i.e., algorithm principle, the scale and type of the dataset. Moreover, the challenges facing the...
Data collection is a very important step and part in the research of energy visualization and analysis. How to make a general, reliable and convenient data collection system is a meaningful and necessary job. In this paper, we introduce a new kind of energy data collection system which is using WiFi module and current transformer. The whole hardware system can be divided into four parts. The first...

With the rapid development of Chinese economy in recent years, the consumption of energy increases greatly. Building energy consumption accounts for a large part of the total consumption. Building energy conservation is an essential and urgent measure to build the conservation-oriented society. In order to obtain the dynamic information of the building energy consumption efficiently and accurately,...
The detection of anomalous trajectory patterns in target tracking is considered here to infer the target's intent which is assumed to be related to the shape of the target's trajectory. The context-free grammar is used to model the trajectory of the target and obtain the mode sequence via the quantification to the state estimate. The modified Earley algorithm is proposed to parse the mode sequence...
This paper aims to the prediction of carbon content in spent catalyst in a continuous catalytic reforming (CCR) plant based on least squares vector machines (LSSVM). When modeling by LSSVM, the problem of optimizing the hyper-parameters draws many researchers' attention. In this paper, a novel hybrid algorithm named IWODE is proposed to deal with it. The algorithm embeds invasive weed optimization...
To guide an autonomous robot in the space of obstacles, an enhanced path planning system including image processing, cluster reduction, path planning and smoothing based on fuzzy inference is proposed in this paper.

In this paper, we extends the existing results on the H∞ control for continuous-time T-S (Takagi-Sugeno) fuzzy systems. A new fuzzy Lyapunov function is considered for ensuring system stability and guaranteed H∞ performance with parallel distributed compensation (PDC).
