In time-sharing measurement method, system self-calibration is very important to improve detection accuracy. In traditional time-sharing measurement method, system self-calibration is finished by lots of targets coordination from NC machine moving. This self-calibration method not only needs complex motion trajectory but also increases repeatability errors. In this paper, a new system self-calibration...
Ion implantation technology is widely used in semiconductor manufacturing process. Most of install base for high current implanters use deceleration technology to overcome space charge effect especially important for low energy implants. It is necessary to consider the Energy contamination (EC) effects on devices with thinner gate height. This paper use SRIM simulation and dopant profiles, offline...
In this study, to realize a platform independent netvideo architecture, the H.264 AVC standard was chosen as a common communication language inside a cascaded net-video system. And then, a novel load-balancing dispatching scheme was proposed and mathematically discussed to overcome the native bottleneck problems of the system.
In this study, to realize platform independent net-video streaming, H.264 AVC standard is chosen as the communication language inside the streaming system. And then, a novel load-balancing dispatching scheme is proposed and mathematically discussed in the paper to overcome native bottleneck problems generated inside a typical net-video system.
The Source Region of the Yangtze River locates in the Qinghai-Tibet Plateau with an area of 142299 km2, which is especially sensitive to global warming because of its high elevation and cold environment. To assess the land use and land cover changes from 1975 to 2005, we employed remote sensing and GIS technology to monitor the area of land use and land cover at four times (1975, 1990, 2000, and 2005)...
The Source Region of Yellow River locates in the northeast of Qinghai-Tibet Plateau with an area of 131419 km2, which is especially sensitive to global warming because of its high elevation and cold environment. To assess the land use and land cover changes from 1975 to 2005, we employed remote sensing and GIS technology to monitor the area of land use and land cover at four times (1975, 1990, 2000,...
Aiming at low efficiency, low accuracy and other issues existing in large lathes geometric precision detection, the paper proposes a new method of measuring geometric precision of lathes. The method is based on the principle of GPS positioning, Using a laser tracker on four different positions, the coordinates of the same target points with a continuous trajectory could be acquired. By a large number...
This paper focuses on the problem of robust reliable control for a class of uncertain switched systems with disturbances and also with actuator failures among a prespecified subset of actuator. Both state matrix and output matrix contain time-varying norm-bounded parameter uncertainties. The purpose of this problem is to design robust feedback-reliable controllers and a switching law such that the...
The Source Region of Yellow River locates in the hinterland of Qinghai-Tibet Plateau, which is especially sensitive to global environment change because of its high elevation and cold environment. Under the influence of global warming, aeolian desertified land expanded rapidly in this area during the last decades. To assess the trends of aeolian desertification from 1975 to 2005, we employed remote...
In wireless cellular system, providing Quality-of-Service (QoS) control during hand-offs is highly desirable. In this paper, a method to estimate hand-off probability using statistically recorded history data of mobile phone's mobility (connection or hand-off) is proposed. By designing a special statistical database structure and casting a three-layer neural network on the history data, the cellular...
In this paper, a novel large size (50x50 mm2) anodic porous alumina membrane specially used in hemodialysis process is developed. By using a two-step anodization fabrication method, a semi-permeable membrane with nano-sized pores is produced. Comparing with spongy style pores located on polymer membranes, this membrane has straight channel pores. And these pores are uniform in size. Experimental results...
Intact method for flow analysis in a hemo-dialyzer is highly desired for the design of hemo-dialyzer or in the ongoing hemodialysis process. MRI and CT imaging technologies have been widely used as tools for tissue, bone, and cancerous clinical analysis etc. In this paper, CT imaging technology is adopted to describe flow pattern within a hemo-dialyzer. And then, an intact image analysis method trying...
