The study aimed to explore the model and context of experiential education applying mobile learning. Each learner is unique and carries her/his own values, perspectives, concerns, problems and agendas to the learning environment. According to this scenario, it is important to construct effective learning activities for supporting performance. We evaluated the program of orienteering training, collaborative...
In this paper, a green communication scheme is proposed for a cooperative network wherein two source nodes send data packets to a destination node with the aid of a relay node. There is a trade-off between the time taken and the energy consumed by the system to complete the transmission of the data packets. A mathematical analysis on the expected cost in time and energy by the system are derived....
Objective: To analyze the component law of Chinese medicines for osteonecrosis of the femeral head, and develop new prescriptions for osteonecrosis of the femeral head through unsupervised data mining methods. Methods: Chinese medicine recipes for osteonecrosis of the femeral head were collected and recorded in the database, and then the correlation coefficient between herbs, core combinations of...
A single chip receiver based on super-regeneration incorporates an on-chip slot antenna and digital received data synchronization. A capacitively-loaded standing-wave resonator improves energy efficiency. An all-digital PLL timing scheme synchronizes the received data clock. The prototype 5 GHz receiver, implemented in 0.13 mum CMOS, achieves a data rate of up to 1.2 Mb/s, dissipates 6.6 mW from a...
A fully integrated super-regenerative receiver in 0.13mum CMOS with on-chip quench generation is described. Auto-calibration improves the selectivity of a Q-enhanced filter and the sensitivity of super-regeneration. The prototype consumes 2.8mW, or 5.6nJ per received bit, at 500kb/s, and has a turn-on time of 83.6mus, a channel spacing of 10MHz, and a sensitivity of -90dBm
Super-regeneration is re-examined for its simplicity and power efficiency for low-power, short-range communication. Although previous approaches rely on a high quality off-chip LC-tuned circuit, this paper describes a fully integrated 2.4-GHz ISM band super-regenerative receiver implemented in 130 nm CMOS. Several new design features, that take advantage of digital processing, are proposed. A synthesizer...
