High-tech industry has become a key component of international competitiveness of one country. This paper analyses the general development of China's high-tech industry and compares it with strong competitive high-tech industries of other countries. And then this paper reveals major problems and challenges faced by China's high-tech industry and also provides strategies for high-tech industry per...
This paper propose a method to deal with the complex nonlinear characteristics, which was caused by the uncertainty of the unknown. As the received signal strength is low in Non line-of-sight environment, the proposed algorithm can be used to process and predict the unknown nodes position by maximum likelihood estimation method. Furthermore, experimental results show that the mobile target tracking...
In this paper, An Average Differential Transmitted Reference (ADTR) Ultra-Wideband impulse radio (UWB IR) system is proposed. The proposed scheme has low complexity and is no need to waste resources for transmitting reference signal. The performance of the proposed system conditioned on a multipath channel is analyzed and simulated. The results show that the proposed system gives a better performance...
A novel scheme for ultra wideband (UWB) transceiver based on decision feedback using average differential transmitted reference (ADTR) is proposed in this paper. The system that averages multiple previous data pulses to form a cleaner template can reduce the noise level, but it does not need to transmit any reference signals before data-modulated waveforms. Furthermore, a combination of direct sequence...
The ankle represents one of the most complex bone structures in human body and the overall ankle motion is therefore complicate. In addition, motion analysis of ankle is a key issue in ankle rehabilitation and in developing an ankle rehabilitation device. Based on the analysis of the structure of ankle and its motion, this paper proposed two types of motion modes of ankle, according to the modes,...
The recent advances in wireless sensor technologies (e.g., Mica, Telos motes) enable the economic deployment of lightweight sensors for capturing data from their surrounding environment, serving various monitoring tasks, like forest wildfire alarming and volcano activity. We propose a novel query called thresholded range aggregate query (TRA), which retrieves the IDs of the sensors for which the average...
