The following topics are dealt with: intelligent system design; neural networks, AI and expert systems; evolutionary computation; genetic algorithms; natural language processing & machine translation; artificial life and artificial immune systems; rough and fuzzy rough set; gray system and cloud computing; cognitive radio and computer vision; pattern recognition and machine learning; fuzzy system...
The mechanism of aircraft skin corrosion is studied and a corrosion detection algorithm based on wavelet analysis is proposed. First of all, the magneto-optic image is decomposed by the wavelet analysis. In the next place a feature vector is assigned whose components represent energy in each sub-image. Lastly, a 1-nearest neighbor method classifier is applied to classify the proceeding feature vector...
This paper introduces an attribute reduction method based on the characteristics of consistent approximation space (CAS) of rough set. The proposed method can be used to fuse alarm signals from different kinds of fire sensors using decision rules derived from a sample data in CAS with the data classification features of CAS. The experiment results of an example data set show that this method can fuse...
This paper proposed a digital offset self-calibration technique for the flash converter of an ultra high-speed folding and interpolating ADC. The chip is processed in 0.18-μm CMOS technology. The measured results show that the digital calibration technique can efficiently improve the ADC characteristics.
Peer-To-Peer (P2P) and Mobile Ad hoc Networks (MANETs) share the same key concepts of self-organization and decentralization, and both aim to provide connectivity in a completely decentralized manner. Routing algorithms for MANETs can potentially benefit from the combination with P2P overlay routing algorithms. Some efforts have been made to integrate P2P overlay into MANETs, but all work is based...
Toxic heavy metals in soil are global problems, due to their hazards to ecosystem and human health. There are seldom researches on risk early warning system of heavy metal pollution. In this paper, a framework of early warning system for pollution risk of heavy metals in soil , combining remote sensing technology and geographic information system. Its purpose is to enable the user of the warning system...
In the paper, a Hendricks Mean Value Engine Model is established by using SIMULINK. At the same time, a fuzzy neural network is designed. The AFR is simulated under transient conditions. The simulation result shows that: With no controller, when throttle degree is changed intensively, the AFR errors are large, With the FNN controller, the AFR errors can be controlled to a narrow range, and the system...
Owing to providing a novel insight for the signal and image processing, compressed sensing (CS) is considered as a promising method for such fields. Successful applications of CS depend mainly on the accuracy and speed of the reconstruction algorithms. Essentially, CS reconstruction process belongs to a discrete inverse problem with finite unknown variables, methods that ensure the numerical stability...
As the greenhouse's control technology is still unpopular in Chinese farm due to its cost and poor control performance, this text introduces a simple temperature & humidity controller based on MIMO fuzzy system. It is made of the single chip ATMAGE, the integrated temperature & humidity senior SHT10 and the driver circuit. It applies fuzzy theory to control the equipment, automatically adjust...
How to discover the services that satisfy the needs of request from the large-scale Grid services repository is a key application of Grid. This paper proposes a method of Grid service discovery based on Grid service ontology index description and ontology matchmaking. It provides a service discovery process by using ontology parser to extract ontology from a service request, and filters many irrelevant...
An improved image signature is proposed and extracted. Firstly, a color information based ICM(Intersecting Cortical Model) image signature is presented. Then a new object feature named SRIC(Silhouette Rotate Interceptive Curve) is described. After these researches, a more distinguishable image signature algorithm based on ICM combined with SRIC is proposed and realized. The Contrast experimentation...
In a complex environment radar plot is often changing dramatically, non-uniform, discontinuous, uncertain and containing lots of false alarms. It is difficult for tracking system to form tracks in such complex environment. Traditional track formation methods can not accurately determine the size of track initiation gate and select specific initiation criteria. In this paper, an intelligent information...
After a brief discussion on the dynamic and geometric orbit determinations, the observation model, dynamic model and Kalman filter for a geostationary (GEO) satellite orbit determination are introduced. A robustly adaptive Kalman filter based on variance component estimation is proposed for orbit determination of a maneuvered GEO satellite. The main idea is to use robust estimation to resist the influence...
