We propose a new vertical handoff method in which the number of signaling and registration processes is lowered as a result of reduced utilization of home agent and correspondent nodes while users are mobile. Throughput performance of the integrated network is improved by reducing handoff delays and packet losses. Special conditions such as boundary condition also considered. Performance and delay...
This paper deals with the problem of output feedback robustly passive control for parameter uncertain systems with time-varying delay. The parameter uncertainties are norm-bounded. We provide a dynamic output feedback controller that guarantees the closed-loop systems strongly robustly stable with strictly passive for all admissible uncertainties. Delay-dependent sufficient conditions for the existence...
In this paper, a novel proportional-integral (PI) switching surface is introduced for determining the synchronization performance of systems in the sliding mode motion. Based on the sliding mode controller, the system is established by a robust control scheme which guarantees the occurrence of a sliding motion of error states even when the parameter uncertainty and external disturbance are present...
During the process of pluralistic fertilization model construction, the unreasonable ratio of nitrogen, phosphorus and kalium easily results in the deviation of fertilizing model. This paper has proposed an adaptive algorithm of fertilization model fitting based mixed intelligent computing of GP/GA, and solved the issue of structure and parameters optimization of adaptive fertilization model. This...
Image segmentation is a technique that partitioned the input image into prerequisite semantic unique regions. Segmentation should stop as object of interest in an application is isolated. The ultimate goal is to make the image more simplified one and that to get more meaningful to analyze. Number of segmentation techniques are available but none of them satisfy the global properties and thus remain...
In this study, we propose that optimization of the input pulse results in a high-speed response and rebound suppression for solenoids. This input is given by two impulse voltage responses. The first impulse response rapidly drives the solenoid plunger, and the second suppresses the rebound that occurs upon reaching the reference position. In the past, these pulse timings have been determined by trial...
A cross-coupled model predictive controller for multi-axis coordinated motion systems is presented by incorporating cross-coupled strategy into the model predictive control architecture. The control law is generated by minimizing a cost function for the augmented system model in which the synchronization errors are embedded. Simulation and experimental results conducted on a high-precision positioning...
In this paper, we propose an efficient and effective method to solve undersampled problem of linear discriminant analysis (LDA) by performing orthogonalization procedure only once in the difference space. Since in the proposed method, the optimal discriminant vectors are immediately obtained by performing orthogonalization procedure once on difference vectors, the efficiency is improved greatly compared...
In this paper presents an authentication protocol for challenge-response exchange in smart card. Cryptographic authentication is necessary to protect branded goods from forgery. Existing protocols do not include cryptographic authentication mechanisms.Therefore, a new approach for authentication is proposed in this paper. Because of the limited computing power, low die- size and low- power requirements,...
This paper focuses on the combination of intelligent, technical and time series techniques. It is necessary to use intelligent series to predict the process of stock price change and deduct the price patterns. In most of the applied intelligent methods, the predictions don't come through. In this project not only the newest intelligent techniques, which are neural and fuzzy nets, are used, but also...
In this paper the time-delay neural networks (TDNNs) have been implemented in detecting the damage in bridge structure using vibration signature analysis. A simulation study has been carried out for the incomplete measurement data. It has been observed that TDNNs have performed better than traditional neural networks in this application and the arithmetic of the TDNNs is simple.
In this paper, a distributed data mining tool that suitable for distributed and isomeric database environment of intelligent control system by borrowing ideas from architecture of grid is introduced. It can also perform incremental data mining based on history mining result. This tool makes full use of metadata of each kind of resources. The resources associated in the data mining are all packed into...
In this paper, to cope with highly nonlinear behavior of a flexible link robot dynamic, a Lyapunov based nonlinear output feedback control strategy directly based on tip position and strain gauge measurements is investigated. Effectiveness and performance of the controller in vibration suppressing and fast motion duration tracking capability is shown through simulation.
This paper presents the design of an autonomous surface vehicle (ASV) used for marine environment monitoring or hydrologic survey. A catamaran is used to improve stability against waves, and the shape of high-speed ship is exploited to reduce the resistance. The characteristics of resistance, electric motor and propeller are optimally matched, so that the battery power is saved and the endurance is...
The weight in TOPSIS approach (technique for order preference by similarity ideal solution - TOPSIS ) is given by experts or decision makers. The value of weight would be influenced by expertspsila subjective judgments. A slight difference in value of weight may result in diversity of order of alternatives. In this paper, a Bayesian method for decision of weight for MADM model with interval data is...
Decision tree based on hiberarchy decomposition is a kind of improved ID3 algorithm. It splits the training set by choosing different key attributes in different layers according to the correlation between classes and attributes. Compared with traditional ID3 algorithm, its rules are simpler and more general. This paper uses the hiberarchy decomposition methods as well as the C4.5 algorithm and makes...
In the field of VAV air-conditioning system (variable air volume, VAV) control theory and practical study, the paper analyzed the methods used by the China's VAV control procedures including static pressure control, variable pressure control and total air volume control, and compared the strengths and weaknesses among them. Based on the analyzing, according to the current VAV control's situation and...
This paper provided a new approach of bridging Web 2.0 technologies and traditional ePortfolio systems to enhance educational benefits to individual users as well as learning community. Reasons for promoting constructive social learning in education were analyzed. Related design problems in current e-learning systems were discussed. The design and development processes for a social learning enhanced...
Here we have presented an alternate ANN structure called functional link ANN (FLANN) for image denoising. In contrast to a feed forward ANN structure i.e. a multilayer perceptron (MLP), the FLANN is basically a single layer structure in which non-linearity is introduced by enhancing the input pattern with nonlinear function expansion. In this work three different expansions is applied. With the proper...
