In order to enhance the efficiency in the process of image fusion, a novel fusion algorithm of infrared and visible images is proposed. First of all, fast finite shearlet transform (FFST) on both the infrared image and the visible image is performed to get a low frequency sub-band and a certain amount of high frequency sub-bands. Then, the Sum Modified Laplacian (SML) fusion algorithm is used for...
Aiming at multi-focus color image fusion, An image fusion algorithm based on the Canny edge detection is proposed. Firstly, the color image is converted into grayscale image, then, the Canny edge detection algorithm is used to detect the edge of grayscale image to obtain the corresponding edge image. Secondly, the area of the two edge images is compared and the isolated point is removed. The stripes...
The thermal resistance of different region in the AlGaAs/GaAs HEMTs is measured in a large temperature range by the pulsed switching electrical method. The thermal resistance of the chip solders and base can be measured, respectively, through the cooling response curve processed by the structure method. As the temperature increases, the total thermal resistance increases by 50% from −20 °C to 150...
The development of information technology brought a new prospect for the network study, the adaptive learning has been possible to meet learner's individual requirements. The learning based on case may provide the simulation situation for the learner, but the adaptive learning takes on the both superiority of the Case-based Learning and simulation situation. It take the case as the study object, shields...
Logistics network design is an important strategic decision. With the development of globalization, more companies outsource their logistics and the third-party logistics companies have become the mainstream. So how to design a reasonable logistics network is important to both manufacturers and 3PL. this article analyses the situation of 3PL and provides a model in logistics network design. Finally,...
China's old-age security system is facing more and more serious challenge from aging population. So it is important to study the feasibility of implementing the reverse mortgage (RM) business in China. This paper compares two types of RM pricing models (non-redeemable RM and redeemable RM), under taking account of borrowers' uncertain expectation. Through theoretical analysis and empirical simulating...
Capital structure has been the focus of the study and theoretical circles, and the optimal capital structure is one of the most important content, this paper attempts to determine the optimal capital structure through fuzzy comprehensive evaluation method. It claims that the optimal capital structure of enterprises should be a region, if an enterprise is not in such a region, it is supposed to adjust...
U.S. financial crisis in 2008 made the deficiencies in risk management of new Basel II exposed. In August 2008 the Basel Committee proposed in the “economic capital model of practice” that it will evolve the framework that assesses the banks' economic capital into the Pillar 2 of Basel II. China is introducing economic capital management system in accordance with the requirements of Basel's new agreements...
The development of mobile devices and the public key infrastructure (PKI) have improved the rapid development of mobile e-commerce. However, there exits some challenges such as limit computing capacity for PKI-based secure transactions. This paper presents a new system architecture which includes client, mobile operator, service provider, certificate authority and so on. On this basis, the protocols...
The widespread usage of the Web and the Internet-as information and communication technologies (ICTs)-is a recent important public sector innovation. Most e-government systems are web applications based on B/S mode. However, these applications have problems such as poor expansibility and bad interoperability. The article proposes the architecture of e-government system based on SOA, which can improve...
Reverse logistics is becoming more important in over all industry area because of the environmental and business factors. Planning and implementing a suitable reverse logistics network could bring more economic profits, customers' satisfaction, and a nice social picture for companies. In the e-commerce environment, reverse logistics indicated some new characteristics, such as intensive, collaborative...
Automatically extraction model, which is based on shape, spectrum, texture and other characteristics information, achieves a better effect in the information extraction of the buildings, but it is difficult to identify the building further. Therefore, this paper proposes we should consider the spatial association features and semantic features characteristic of the objectives when identifying the...
With development of RS and GIS, research in land use is a hotspot at present. Using RS images in 1986 and 1996 as data source; synthesizing to carry on land use classification of Xian Tao city. The law of land use changes is: cultivated land area has been declining; woodland is in a little growing magnitude; water and unused land grow to the high trend. Comprehensive index of Xiantao land use increases...
The quantitatively researching urban spatial characteristic is very helpful for urban management and planning. The process and characteristics of urban expansion are analyzed with fractal dimension and compactness based on spatial morphologic measurement. Yiwu city is selected as a study case with 4 Landsat remote sensing images abstracted in 17 years, including 1986, 1991, 1997, and 2002. The spatial...
The multi-band orthogonal frequency division multiplexing (MB-OFDM) scheme is a promising candidate proposal for the high rate ultra-wideband (UWB) wireless personal area networks (WPAN) (IEEE 802.15.3a) physical layer standard. Focusing on the system simulation and performance comparison between two different modulation techniques, we design a high rate MB-OFDM UWB system with convolutional code...
