This paper experimentally demonstrates a saw-tooth diffuser/nozzle valveless micropump. The saw-tooth diffuser/nozzle pipe is fabricated on chrome glass substrate using MEMS technology. A PMMA material is used to manufacture the pump chamber. The vibration of piezoelectric cantilever drives PDMS diagram to do reciprocating motion. It has been shown that the steady flow rate of the saw-tooth diffuser/nozzle...
We present a novel security monitoring framework for intrusion detection in IaaS cloud infrastructures. The framework uses statistical anomaly detection techniques over data monitored both inside and outside each Virtual Machine instance. We present the architecture of our monitoring framework and describe the implementation of the real-time monitors and detectors. We also describe how the framework...
The segmentation of Chinese words from text documents is one of important contents of Chinese information processing. After every segmentation of Chinese words is obtained by the Chinese word rough segmentation by maximum match and ambiguity detection algorithms, each word in every rough segmentation is tagged by Viterbi algorithm according to HMM model of part-of-speech tagging. At last, each rough...
This paper analyzes data differences among different scale road networks and points out that topology matching is improper in multi-scale road networks. In order to build relation among identical entities from different scale road networks, this paper concludes that geometry matching, attributes matching and composite matching methods should be adopted. Because a great amount of uncertainties exist...
It is to study a new hierarchical intelligent control system in the vehicle's steering antilock brake stability fields in this paper. A layered control system consisting of the execution layer and the cooperation layer is designed. On the execution layer, optimal sliding mode controller based on genetic algorithms is designed for the automotive brake controller. Optimal sliding mode controller based...
To make mass distributed heterogeneous data resources in all areas share and manage easier. The database grid service is proposed. It devotes integrating database into Grid environment with grid service. A deep research was taken on the grid service development tools GDT(Grid Development Tools) and GT4(Globus Toolkit V4.0) which is a services container. A integrated development environment was built...
It is reported that circulating miRNAs are potential new biomarkers for diagnostic and other clinical applications. To study the varieties of plasma miRNAs expression, we investigated maternal plasma miRNAs expression profiles using SOLiD sequencing technology. The results showed that the distribution and abundance of specific miRNAs in plasma are varying during physiological pregnancy process. We...
For the uncertainties of the vehicle steering system, a method of equal control is used. The equal control input is calculated based on the certain part of the steering system, and a RBF network is used to apply the switch control input by compensating the uncertainties. The simulated results show that the twitter using the method presented in the paper is smaller than the strategy using fixed control...
Detecting the intrusion usually depends on predicting the regular data traffics in wireless sensor networks. However, in fact, the data traffics are certainly affected by noise. In this paper, the theory of wavelet threshold is adopted to remove noise to increase the forecast accuracy of data traffics in WSN. Several numerical simulation verified that the forecasting precision is high, and achieved...
The industry-university-research cooperation system is a complex system, which has self-organization trait once the system is established that is same to other dissipative structure systems. The cooperation system evolution process includes three stages and has a complex structure. The industry-university-research cooperation system is a system includes many subsystems. The stabilization and mutual...
This paper puts forward a new improved perception algorithm based on solution region by analyzing the pattern's solution geometric characteristic in space. The algorithm could find a better solution vector in solution region on condition that the pattern's linearity is separable. Otherwise, it indicates the linearity isn't separable. That is, it can discern that the solution region doesn't exist....
Considering the current status of college students practice teaching, this paper proposes the necessity and importance of the Universities building research-based practice teaching base, which discussed some methods and measures for building research-based practical base. For the selection of research subjects in the research-based practical teaching, this paper proposed that from the teachers of...
Using the multi-objective hybrid simulated annealing algorithm, this paper optimal design the three-phase induction motor. Typical examples of optimization show the efficiency and feasibility of this method.
Schema matching is a difficulty in many database application domains, e.g., data integration, E-business, data warehousing and semantic query processing. We can get correct schema mapping by mining the semantics of elements from the elementspsila own information (e.g., elementspsila names and elementspsila data types and domains), data instances and structure information. But in fact, most existing...
The product-harm crisis management affects consumerspsila purchasing behavior and it is important for the enterprise to evaluate the effect and understand the evolution. In academic field, may scholars have paid their attention to the subject, but most of existing researches assume that all consumers have the non-differential purchasing behavior, which is unacceptable for diverse personality in the...
