For the purpose of filtering road spectrum this paper proposed an adaptive Kalman filtering (AKF) algorithm based on accurate autoregressive (AR) model. The proposed AKF can overcome the disadvantages such as complicated computation process and poor real-time performance when applying normal AKF. The algorithm can implement AKF by adjusting gain matrix Kk on the base of innovation. The process of...
Coordinated animal behavior is abundant in nature, such as the uniform moving phenomenon among bird flocks, the collective evasion maneuvers of fish schools. To explore the appealing inter-individual interaction mechanism governing the abundant biological grouping behaviors, more and more efforts have been devoted to collective motion investigation in recent years. Previous research claims the existence...
The growth and popularity of Web services make personalized recommendation as one of the most important research issues in service computing, which can help service users find the optimal Web services from large functionally equivalent service candidates according to the Quality-of-Service (QoS). Although significant works have been done on improving prediction accuracy by employing collaborative...
In this paper, we introduce a novel block-based multiscale error concealment method using low-rank completion. The proposed method searches for similar blocks and utilizes low-rank completion to recover the missing pixels. In order to make the full use of the hidden redundant information of images, we seek for more similar blocks by building an image pyramid. The blocks collected from the pyramid...
With the rapid increase of growth and development in cloud computing it is clear to see that it is becoming a common trend within the industry leading to the adoption by businesses and Information Technology (IT) users alike. Coupled with this trend comes a vast amount of academic research into the cloud computing industry covering most aspects but still leaving some untouched. There is, however,...
In this paper, using observed data, the characteristics of two different feature of one heavy snowfall in North China region from 25 to 27 February, 2011 are studied. Results show that the heavy snowfall can be divided into two stages. The snowfall happened in same background circulation, but showed two different characteristics. First, the affecting systems of two stages of snowfall are different:...
Ionic liquids constitute a new class of substances that are considered as potential substitutes for many traditional organic solvents in reaction and separation systems. But there is still a lack of transfer data due to the deficiency of research on the flow behavior. In this work, the motion and deformation of single bubbles rising in quiescent ionic liquids were investigated by injecting bubbles...
For the provision of dependable search and rescue capability in dynamic and unpredictable disaster areas, each networked node should have ability to (1) autonomously support and co-operate with each other in a peer-to-peer (P2P) manner to quickly discover and dependably self-configure services available on the disaster area to deliver a real-time capability; (2) modify their behaviours to deliver...
