Tip-based nanolithography provides a flexible nano-lithographic technology. The tip fabrication is the main challenge of the technology. The combination of reactive ion etch and electrochemical machining provides a cost-efficient method for tip fabrication with nanoscale tip openings. In this paper, we investigated the effects of different photoresist thicknesses and electrochemical machining times...
ZigBee is widely used in many fields for its low cost, low power. This paper discussed the network topology, device type and protocol architecture about ZigBee protocol and introduced CC2530 chip. Then we used Z-Stack protocol stack for networking and did some tests based on the previous content, such as the network communication distance and packet loss rate test. Test results show, ZigBee networking...
This paper introduces a tunnel procedure based on the virtual network card. The data through the tunnel are encrypted by using the open source library OpenSSL. Through this program we can implement an intelligent home control center VPN system base on Android that can protect the information which collected by wireless sensors at home on the Internet.
An information system for the individual care management was proposed in this paper, which is an embedded physiological data acquisition system based on ATMEL9260 utilizing the combination of wearable physiological detecting technology, sensor technology, electronic technology and network technology. It realized continues and long-term detection of physiological data, contributing to real-time monitoring...
This paper is aimed to illustrate a framework of the design of call center service management system which is used to help call center's managers to manage call center's service level. It introduces the architecture of call center service management system which is based on Pentaho business intelligence Platform, and the key technologies on data analysis, such as OLAP. This framework first integrates...
This paper proposed a new face recognition method based on texture features of gray-level co-occurrence matrix (GLCM). The feature vector is constructed based on GLCM texture features using hybrid projection function in nonsubsampled contourlet transform domain. The experimental results on CMU PIE database demonstrate the efficacy of the new method.
This paper obtains with conventional 2D displays and vision principle, firstly, this paper obtained the relationship between 3D display and conventional 2D resolution by an elaborate and detailed analysis and calculation, then it concluded the universal design method about the freedom of stereoscopic display, the law about general design of Fusion Table. Finally, using fusion table described in this...
Wireless HART technology provides a robust wireless protocol for the full range of process measurement, control, and asset management applications. Wireless HART is a wireless mesh network communications protocol for process automation applications.
This paper describes the basic principles that using adaboost arithmetic to achieve face detection, through OPENCV software, selects the expansion of the harr-like characteristics and achieves the training of face detection classifier. Finally, we analyze how the number of the classifiers affects the results of the experiments, and then we give a more appropriate general size for the samples after...
Deposition of amyloid-β peptide (Aβ) in the diabetic brain is poorly understood. Low-density lipoprotein receptor related protein 1(LRP1) at the blood–brain barrier (BBB) is critical for regulation of Aβ homeostasis in the brain. In this study, we used streptozotocin-induced diabetic mice to observe the expression of LRP1 at the BBB by Western blot and immunocytochemical analysis, and to study in...
With the interface from words to graphic, the quality of application program is more and more depend on the degree which the graphic interface feat the taste of the users. So if we can predict the users' taste of the style of application program, our work must be more popular. Now with the help of BP-neural network we can do it because of its strong capacity of prediction.
Based on a parametric planar rotation updated algorithm and the deflation technique, a blind signal extraction method is proposed in underdetermined mixtures. While extracting one, source signal from the mixtures and keeping size of the mixtures, a separated signal is concealed from the mixtures using the deflation technique. This procedure is repeated for the deflated mixtures until all source signals...
A kind of adaptive PID control algorithm is analyzed, and the drawbacks of the existing algorithms are commented. As an improvement, a neural network intelligent control algorithm based on one-step prediction is developed. Result show that the new control method is more adaptable to the control of time-varying and nonlinear control systems.
