Accurate localization is crucial for wireless ad-hoc and sensor networks. Among the localization schemes, component-based approaches specialize in localization performance, which can properly conquer network sparseness and anchor sparseness. However, such design is sensitive to measurement errors. Existing robust localization methods focus on eliminating the positioning error of a single node. Indeed,...
Digital assets are strategic resources to provide content service and market competition for media organizations, and it is of important significance to set up management and operation model based on the value increment of digital assets. This paper first puts forward the value chain model of the media business based on digital asset management. It then sets forth key resource and core business process...
Crop is often suffered from drought in semi-arid rainfed agriculture area. Diagnosis of crop drought status is critical for prediction of agriculture drought in this area. Two experiments were conducted for find out spr-wheat canopy spectral characters measurement in different water control status in field in 2007 and 2008, and the experiment included two cultivars and four levels of drought. Hyperspectral...
Background: CD44v6 is a splice variant of CD44 (CD44v) could probably promote cancer cells to adhere to vascular endothelium and base membranes and enhancing the invasion and metastasis of colonic carcinomas. Heat shock protein 72 (HSP72) as a molecular chaperone has been confirmed to overexpress in epithelial carcinoma cells. There may be a possible correlation between the expression of HSP72 and...
Focusing on the function shortage and low productivity of existing testing equipment in the semiconductor rectifier bridge manufacture procedure, we designed a master-slave structure testing system. In this system, a PC acts as host processor, and several distributing local single chip micro controllers(SCMs)act as slave processors. The SCMs mainly perform classification and testing each rectifier,...
A new and practical solution, Quantum-behaved Particle Swam Optimization (QPSO) algorithm, is applied to Aeroengine maximum thrust optimization implemented for some turbo fan engine. Simulation is carried out under different altitudes and velocities and shows that thrust can be increased by 7%~9%, 3%~5% more than by Particle Swam Optimization (PSO) algorithm. The influence of initial values on PSO...
An automatic image processing method is proposed to extract vocal fold vibrations from high-speed digital imaging. Extracted regular vocal fold vibrations contribute to periodic voices, and irregular vocal fold vibrations contribute to aperiodic voices. The effects of image resolutions are investigated. This study combines the features of both image and voice signal processing and provides a valuable...
This paper proposes an improved estimation of distribution algorithm(EDA) based on a class of nested Archimedean copulas which is constructed with Lévy subordinators(LNAcopula-EDA). Utilizing of Lévy subordinators, a class of nested Archimedean copulas has been conveniently constructed. In order to exploit EDA to solve high-dimensional continuous optimization problem, we fully use of the capability...

Simultaneous optimization of LDD and Anti-punch-through implant conditions for ESD performance of very large width silicided output driver nMOSFET without snapback mode of operation is reported. Physical mechanisms responsible for performance improvement and device sensitivity to pulse rise time, with little or no dependence on TLP pulse width are detailed.
Biosensors based on SPR (surface plasma resonance) are attracting more and more attention from academic and industry communities. Its principle was interpreted. A novel detector based on SPR was presented for Chromatography. Associated with ion chromatography system, it was employed to detect separation behavior of mixture including glucose, fructose and galacitiol. Experimental results demonstrated...
Intensity-modulated surface plasmon resonance (SPR) array sensor based on polarization control was introduced and the impacts of incident angle, gold firm thickness, polarizer angle, wavelength and data processing on its sensitivity and measuring range were analyzed. It was concluded that in an easily controllable measurement range, an appropriate parameter selection can be set and produce high sensitivity...
Pub/Sub Systems is well suitable for asynchronous exchanging information in distributed systems. However, owing to the existence of numerous communication participants from diverse organizations under an anonymous communication mechanism, the semantic heterogeneous issue in event-matching is fundamental. It affects the accuracy and comprehensiveness of event matching. But most existing content-based...
To construct a recombinant vaccine alpha-fetoprotein (AFP)-heat shock protein (HSP70) complex, and study its ability to induce specific cytotoxic T lymphocyte (CTL) response and its protective effect against AFP-producing tumor. A recombinant vaccine was constructed by conjugating mouse heat shock protein 70. By way of intracutaneous injection, mice were primed and boosted with recombinant vaccine...
There are three kinds of blood vessel systems in liver and these different kinds of vessels are typically visible in each phase of contrast enhanced liver CT Data. In order to merge the different information into one image, image registration should be applied. In this paper, a hybrid image registration for different phases of contrast enhanced liver CT data was studied. Firstly, a rigid registration...
In wireless sensor networks, mobile sensors are often employed for enhancing the sensing coverage and detection accuracy. Current approaches assume mobile sensors with the capability of arbitrary movement. The usage of such sensors with unlimited mobility, however, requires complicated sensor manufactures and high intelligence of movement which are practically unrealistic in many practical applications...
CT and MR images have been used in the liver disease treatment. In order to merge the different information into one image, image registration and data fusion must be adopted. In this paper, image registration and data fusion for MR and CT images of liver was studied. Firstly, the maximization of mutual information method was proposed to register the images. Then, some optimization algorithms, such...
Audio-visual automatic speech recognition (ASR) is a hotspot in field of human-computer interaction (HCI).

A novel speech segmentation approach combining Otsupsilas method with traditional short-time energy and zero-crossing rate (ZCR) based method was proposed. The experimental...
Localization is crucial for wireless ad hoc and sensor networks. As the distance-measurement ranges are often less than that of the communication range for many ranging systems, most communication-dense wireless networks are often localization-sparse. Consequently, most existing algorithms fail to provide accurate localization supports. In order to address this issue, by introducing a concept of component...
