To better identify the objects in remote sensing images, the multispectral images with high spectral resolution and low spatial resolution, and the panchromatic images with high spatial resolution and low spectral resolution need to be fused. Many fusion techniques are discussed in the recent years to obtain images with high spectral resolution and also high spatial resolution. In this paper an image fusion technique, based on integrating both the Intensity-Hue-Saturation (IHS) and the Discrete Wavelet Frame Transform (DWFT), is proposed for boosting the quality of remote sensing images. A panchromatic and multispectral image from Landsat-7(ETM+) satellite has been fused using this new approach. Experimental results show that the proposed technique improves the spectral and spatial qualities of the fused images. Moreover, when this technique is applied to noisy and de-noised remote sensing images it can preserve the quality of the fused images. Comparison analyses between different fusion techniques are also presented and show that the proposed technique outperforms the other techniques.

In this paper a parametric lineal model of heading is obtained, using a remote experimentation platform for marine vehicles. This platform has an in-scale fast-ferry physical model, TF-120 which is autonomous and has all the elements required to emulate a real vessel. The physical model is controlled remotely from a PC using Wi-Fi communications. The tests for the data acquisition with the platform for marine vehicles were carried out in the surroundings of the Bay of Santander. The parametric model identified is used to design a PID controller for heading autopilot and a simulation of this system is performed in Simulink.

In this work, different relaxations applicable to an MPC problem with binary control signals are compared. The relaxations considered are the QP relaxation, the standard SDP relaxation and an alternative equality constrained SDP relaxation. The relaxations are related theoretically, and both the tightness of the bounds and the computational complexities are compared in numerical experiments. The result is that for long prediction horizons, the equality constrained SDP relaxation proposed in this paper provides a good trade-off between the quality of the relaxation and the computational time.

This paper introduces a new Motion-SPM (Smart Power Modules)module in Single In-line Package(SIP), which is a fully optimized intelligent integrated IGBT inverter module for up to 1kW low power motor drive applications. This module offers a sophisticated, integrated solution and tremendous design flexibilty. It also takes advantage of pliability for the arrangement of heat-sink due to two types of lead forms. It utilizes non-punch-through (NPT) IGBT with a fast recovery diode and highly integrated building block, which features built-in HVICs and a gate driver that offer more simplicity and compactness leading to a reduced costs and high reliability of the entire system. This module also provides technical advantages such as the good thermal performances through IMS (Insulated Metal Substrate), the high latch immunity. This paper provides an overall description of the Motion-SPM in SIP as well as actual application issues such as electrical characteristics, circuit configurations and power ratings. © 2008 IEEE.

In this paper the realization and implementation of a multi-controller scheme made of a finite set of linear multiple-input-multiple-output controllers, possibly having different state dimensions, is considered. The problem of bumpless switching between the active controller acting in closed-loop and another controller in the set of controllers waiting to take over the control loop is addressed. A non minimal parametrization of the set of controllers such that all controllers share the same state variables is presented, and it is shown that such a parametrization guarantees bumpless switching between any two controllers within the controller set. © 2007 EUCA.

Strain sensing method based on the measurement of the reflected bandwidth from tapered fiber grating

Guangdianzi Jiguang/Journal of Optoelectronics Laser 2007年第5期18卷 600-602页

We demonstrate the feasibility to make a temperature-independent strain sensor by measuring the bandwidth of the reflected light from the tapered fiber grating (TFG). This simple and low-cost sensor approach has a considerable potential, particularly application to strain sensing in the smart structures. The experimental results show that the method is suitable for distribution measurement, and it can restrain the influence of source fluctuation.

This paper presents a design method of control systems such that a designer can flexibly take account of tradeoffs between evaluated uncertainty ranges and the level of control performance. The problem is reduced to a BMI problem and approximately solved by LMIs. The convergence of the proposed approximation is proved in a modified sense. A numerical example shows the effectiveness of the proposed method in comparison with the standard robust control.

Data Modeling is an essential first step for data preparation in any data mining procedure. Conventional entity-relational (E-R) data modeling is lossy, irreproducible, and time-consuming especially when dealing with unstructured image data associated with complex systems like the human brain. We propose a methodological framework for more objective E-R data modeling by eliminating the structured content-dependent metadata associated with the unstructured data. The proposed method is applied to epilepsy-related image data and a system called the human brain image database system (HBIDS) is developed accordingly. Supported with navigation, segmentation, data fusion, and feature extraction modules, HBIDS provides a content-based support environment (C-BASE). Such an environment potentially provides an unlimited (ad hoc) query support with a reproducible and efficient database schema. Switching between different modalities of data, while confining the feature extractors within the object(s) of interest, HBIDS yields anatomically specific query results. The price of such scheme is large storage requirements and relatively high computational cost. Examples of navigation through unstructured image data and content-based retrieval are presented in this paper. The results show the potential of HBIDS in content-based data management for decision support systems in real life medical applications. © 2007 IEEE.

According to the Gestalt principals, in this paper, we model features for measuring the attraction degree between couples of image components, and grouping areas in trademark images are recognized. This investigation would be used for content-based image retrieval from the view of mirroring human perception for images. The features of proximity, shape similarity, closure, and good continuation are extracted from every combination of two components in an image. After that, according to results of the judgments, a grouping pattern for the query is fixed. Besides, changing combination of the features, the proposed method can output plural grouping patterns. In the experiments, we have evaluated the proposed method on 74 test images comparing between outputs by the proposed method and grouping patterns for the test images obtained from results of questionnaires by 104 participants.
