Wuhan city is the core city of Wuhan city circle and the major city of the Yangtze River, and the change of water have attracted great attention. Using the techniques of "3S" and landscape ecology, based on 1991 and 2009 Landast TM remote sensing image, integrating with the change of water modeling, transform matrix, the shift of gravity centers and landscape pattern analysis software Fragstats3...
This paper, with the help of global and local spatial autocorrelation methods, analyzed the spatial differences among the level of regional economic development and the economic growth rate in Shandong Province with data of county GDP per capita and GDP per capita growth rate from 1995 to 2007. The results showed that: (1) in the study period, the spatial difference among the county-level economy...
Aiming at the practical requirement of communication equipment training simulation field, in order to develop an 3D equipment training simulation system, a networking based simulation architecture charactered with network-in-loop was presented making reference to basic concept of man-in-loop. Principle and architecture were detailed within this architecture. Key technologies of 3D modeling for equipment...
In this paper, two audio scrambling algorithms, which are efficient and can be used to scramble audio sequence independently, are presented first. Then, a new method which combines the two algorithms together using one more parameter is proposed. Compared with the former two methods, the new method has stronger anti-decryption capability. Experimental results show that this method has the advantage...
The properties of average short-term entropy of audio sequence are discussed in this paper. It is discovered that the changes of average short-term entropy on different scales depict the audio's statistical features well, which can be used to generate zero-watermark of an audio clip. A method of calculating normalized entropy vectors is presented in this paper. To generate the zero-watermark of an...
Jabil is well known as a model of workcell production. In the past few years, Jabil (Guangzhou) starts to apply the workcell production principles in managing a supply chain, resulting in better control on the demand and supply uncertainty among multiple supply chain partners. Here a new supply chain management mode-Workcell-based Supply Chain Management (WSCM) is proposed. The WSCM is customer-centered,...
Adder circuits have been extensively studied. Their formal properties are well known, but the proofs are either incomplete or difficult to find. This short contribution intends to integrate all formal proofs related to adders in a single place and to add the details when necessary. The presentation is accessible to general VLSI designer. Another goal of this study is to put together relevant materials...
Service level agreement based on dynamic IT can make it possible that Business managers can chose by them about IT service them need and service level agreement is composed of chosen service items. So service level can change by the business development. Service level is combination with service items.
A hydrogen sensor based on InGaN/GaN multiple quantum wells (MQWs) was fabricated. A gate dielectric HfTiO was added to stabilize its performance at high temperature. Its hydrogen-sensing properties were studied at high temperatures from 100??C to 500??C. The sensor showed promising hydrogen-sensing properties over a wide temperature range, and could still function beyond 500??C.
BSM Business Service Management analysis requirement from business to IT system specially to software. And help CIO make the strategy of software maintenance. Framework of software maintenance based on BSM has six steps. Maintenance software according to BSM can help CIO to balance IT cost and profit and make software available.
