Endmember extraction is a critical step of spectral unmixing. In this paper, a novel endmember extraction algorithm based on evolutionary multi-objective optimization is proposed for hyperspectral remote sensing images. In the proposed method, endmember extraction is modeled as a multi-objective optimization problem. Then the root mean square error between the original image and its remixed image...
In RFID-enabled applications, when a tag is put into use and associated with a specific object, the category-related information (e.g., the brands of clothes) about this object might be preloaded into the tag's memory as required. Since such information reflects the category attributes, all tags in the same category carry the identical category information. To collect this information, we do not need...
Radio Frequency Identification (RFID) technology has been widely used in missing tag identification to reduce the economic loss caused by theft. Although many advanced works have been proposed, they cannot work properly in an open RFID system with unexpected tags. To solve the problem, this paper proposes an order-based missing tag identification protocol (OMTI) that efficiently identifies all missing...
N-1 security criteria is a key principle for distribution operation. However, it is hardly taken into account in modern distribution feeder reconfiguration models, which cannot satisfy security margin demands. To address this fundamental problem, this paper develops a new stochastic reconfiguration method for distribution network considering N-1 security and net loss. Firstly, three indexes-average...
In this paper, the radial pulse waveforms of the same subjects under various contact pressures were measured. Then, the feature points of the pulse wave contours were extracted and the physical parameters were calculated corresponding to different contact pressures. The various trends of parameters, including peripheral augmentation index, peripheral subendocardial viability ratio, and peripheral...
The margin system is the exchange's first line defense against default risk. The margin setting model of stock index futures established adopts improved BP neural network technology, which utilizes Genetic Algorithm (GA) to optimize the weight of BP neural network to expand the search space and enhance learning efficiency and accuracy of the network. Taking Hong Kong Hang Seng Index Future as the...
The problem how to evaluate the provided alternatives and determine a suitable one does exist in the process of distribution network planning. On the basis of the existing methods of multi-attribute decision-making (MADA) and combining non-linear programming with the theory of combination evaluation, this paper for the first time constructs an MADA system based on combination evaluation method for...
The procedure of comprehensive decision-making in urban power system planning is to solve a multi-attribute decision-making (MADM) problem. At present there are many methods for decision alternatives (DA) selection in urban power system planning, such as analytic hierarchy process (AHP) and fuzzy comprehensive judgment, most of which have the defects like large amount of calculation and the big subjective...
A complex system, an industrialized process that invariably involves multiple factors, such as environmental management, human relationship and equipment may result in hazard event. However, the analytical hierarchy process(AHP), provides a methodology for multi-criteria analysis and decision making, can offer decision making support technique to help people prevent the hazard event from taking place...
