Considering a sensor network deploying a large number of nodes, a new joint recovery algorithm is proposed for multiple sensor signal. The number of measurements at each sensor can be reduced in the case of efficient sensing by using proposed algorithm. Reducing measurement number of sensor is an efficient approach to decrease the energy consumption and extend lifetime of sensor networks. In this...
Seven triterpenoid saponins, including four new compounds, catunarosides A–D (1–4), and three known compounds, swartziatrioside (5), aralia-saponin V (6), araliasaponin IV (7) were isolated from the stem bark of Catunaregam spinosa, a Chinese mangrove associate. Their structures were elucidated on the basis of their spectral data and hydrolysis experiments. The antifeedant activities of compounds...
The advantages of the problem-based learning mode which was used in the personnel training of information technology was introduced. And its' specific process was described in details. The influence factors of PBL teaching effect were analyzed. The solutions which were based on information and communication technology (ICT) were raised to improve the effect. In practice, according to a variety of...
In the design of Viterbi Decoder of punctured convolutional codes, the SST method is used to reduce power consumption in this paper. Moreover, the punctured vector table is optimized by hard wire logic, thus reducing the area required by the system. Effective operation of adjustment is used to reduce the word length of path metric memory. At the same time, this algorithm can also help reduce operation...
