A novel complex background suppression based dim point target detection algorithm is presented in this study. Comparing with existing spatial-filter-based background suppression algorithms, the nucleus similarity degree (NSD) of each pixel is analyzed first, then the complex background is predicted by fusing results of two different predictors, and the complex background is removed by subtracting...
This article is about the technology of using Otsu algorithm to binary the license plate image. Meanwhile, the author presents the theory of Otsu algorithm, and the theories of binarization method to deal with gray-scale image of the license plate. Then the results of the license plate image binarization based on MATLAB are presented.
As you know, service quality is a comprehensive annotation to test the satisfaction of a service, or quality of service. The paper introduces the service quality technical model and the web site client multimedia Service Quality. Then we can help you establish a complete information model of service quality.
Analysis and research of information and Internet protocol version RIP authentication key does not match the two common faults, And propose solutions to improve the packet transmission efficiency and reduce message latency.
To some extent, the paper analyzes the principle of hierarchical reconstruction of the impact of the robot. Image recognition is given to the affine point from the image reconstruction of the corresponding instance of calculated measures, which is a measure of the corresponding affine point reconstruction needs of the most basic structural information, such as metric reconstruction of seculars reflection...
Human coronavirus (HCoV) NL63, a newly discovered coronavirus, has been associated with acute lower respiratory tract infections (ALRTI). We detected HCoV-NL63 via reverse transcriptional PCR (RT-PCR) in eight out of 878 respiratory specimens freshly collected from hospitalized children with ALRTI between April 2006 and March 2008 in Children’s Hospital of Chongqing Medical University. Peak of HCoV-NL63...
Rapid development of the Intelligent Transportation Systems (ITS) has greatly increased the traffic safety. In order to improving the safety status caused by drink driving in China, a questionnaire study was conducted with drink driving behaviors in Beijing to help understand the attitude, subjective norm, perceive behavioral control and intentions of drink driving in Beijing using the theory of planned...
Relevance feedback is an iterative search technique to bridge the semantic gap between the high level user intention and low level data representation. This technique interactively determines a user's desired output or query concept by asking the user whether certain proposed 3D models are relevant or not. For a relevance feedback algorithm to be effective, it must grasp a user's query concept accurately...
Relevance feedback is an iterative search technique to bridge the semantic gap between the high level user intention and low level data representation. This technique interactively determines a user's desired output or query concept by asking the user whether certain proposed 3D models are relevant or not. In the past, most research efforts in 3D model retrieval field have focused on designing algorithms...
E-commerce is an increasingly important channel for retailing commerce and business transactions. In order to solve the problems for lacking of both realistic for the goods presentation and the friendly interaction with user on the traditional E-commerce Websites, showing goods in a 3D circumstance and applying 3D retrieval tool are very useful in E-Commerce system. In this paper, we present X3D technique...
A new algorithms based on discrete Hopfield network(DHNN) are proposed to blindly detect multi-value signals in this paper. Based on the relationship between received signals and projection operator of transmitted signals, the paper will construct new optimization performance functions to blindly detect signals, A quadratic programming performance functions with alphabet constraints is mapped to energy...

Each year, there are kinds of new diseases or natural disasters that break out around the world. And, the emergency logistics system plays an important role in the process of fighting against these diseases and natural disasters. How to evaluate and optimize the emergency logistics system in contingencies is becoming the hot researching topic. This article establishes the set pair analysis model (SPAM)...
A Constant-gm CMOS operational amplifier with rail-to-rail input common-mode voltage range has been designed. The input stage is based on two pairs of single p-channel differential pairs and two identical n-channel source followers as DC level shifters, which realizes rail-to-rail input swing. To attain a constant-gm over the whole common-mode input range, the compensation circuit which is based on...
As the typical application of intelligent transportation system (ITS), highway tunnel surveillance and control system (HTSCS) is the critical system to improving the transportation safety and efficiency of highway tunnel. In this paper, a HTSCS performance assessment model which employs failure rate (probability of top events) as the performance index based on fault tree analysis (FTA) method is presented...
Container terminal and other related enterprises have formed a service chain spontaneously because of market mechanism, but the cooperation along the chain is loose due to the lack of relevant service supply chain theories. In order to introduce some best practices from manufacturing to service processes, this paper proposed a totally new perspective-container-terminal-centered logistics service supply...
MgXZn1-XO, a ZnO-based ternary compound, has been recognized as a promising material to be used in UV light emitting devices, UV laser diodes and UV detectors. In this paper, a batch of MgxZn1-xO films were fabricated using radio frequency sputtering on glass substrates with a Mg0.32Zn0.68O target. Then the structure and the optical properties of these films after being treated at different annealing...
In order to investigate the effects oxygen defect on the electronic structure of SnO2, the structural change, band structure, density of states, and electron density difference of (11macr0) surface of SnO2 in the rutile lattice phase were performed by the first-principles calculation of plane wave ultra-soft pseudo-potential technology based on the density function theory. The calculated conclusions...
After time-based competition was put forward in 1988, total cycle time has long been recognized as an important metric for assessing the performance and competitiveness of a supply chain. Total cycle time management paradigm of supply chain is a managerial philosophy. Total cycle time management seeks to reduce total time required to perform all the activities that occur in the entire supply chain...
This paper analyzes the problems of channel coordination in multistage supply chain systems, which is dynamically constructed based on customer demand. Firstly, the abstract agent model and the supply chain systems based on multiagent systems are proposed. Secondly, we analyze the optimal product price and optimal production/order quantity of the centralized supply chain systems, and on the basis...
