—Precision irrigation in fuzzy control system based on crop water stress acoustic monitoring was designed in the paper. Moreover, conventional double fuzzy control model was found to carry out two work mode, normal irrigation and precision irrigation, which aims to both ensure normal growth of crops and achieve effective water-saving. Since five input(More)
OBJECTIVES To evaluate the feasibility of dose-modulated retrospective ECG-gated thoracoabdominal aorta CT angiography (CTA) assessing abdominal aortic intimal flap motion and investigate the motion characteristics of intimal flap in acute aortic dissection (AAD). MATERIALS AND METHODS 49 patients who had thoracoabdominal aorta retrospective ECG-gated CTA(More)
A wireless video communication system applied to plant disease control is introduced in this paper. The system is used to acquire and transmit the field plant image or video data for subsequent monitoring and diagnosis. It is based on the DSP TMS320DM642 and nRF24L01 single chip 2.4GHz radio transceiver. It has two data compress and transmission tactics to(More)
A computerized and automatic precision irrigation system based on estimation of crops water stress with acoustic emission (AE) technique was developed in the modern greenhouse. The system can automatically acquire the real-time AE signals and transpiration data from tomato crop respectively with AE sensor and electronic balance, The system also can(More)
α-Catenin is an important molecule involved in the maintenance of cell-cell adhesion and a prognostic marker in cancer since its expression is essential for preventing cancer metastasis. However, the mechanism that leads to the downregulation of α-catenin in cancer progression remains unclear. The present study revealed that lipopolysaccharide (LPS)-induced(More)
OBJECTIVE To explore the clinical value of low-dose prospectively electrocardiogram-gated axial dual-source CT angiography (low-dose PGA scanning, CTA) in patients with pulsatile bilateral bidirectional Glenn shunt (bBDG) as an alternative noninvasive method for postoperative morphological estimation. METHODS Twenty patients with pulsatile bBDG (mean age(More)
The character of gas moving and air flow in heading laneway of underground coal mine was analyzed. Moreover, conventional double fuzzy control model was found to carry out two work mode, normal ventilation and gas discharging. In order to enhance the learning capabilities of the system to the environment, self-learning fuzzy model for auxiliary fan was(More)
RFID technology, USB communication technology, on-line battery internal resistance monitoring technology and virtual instrument host computer scheme with database technique was adopted to establish an original VRLAB detection and maintenance system, whilst the software and hardware design was completed. Current system has solved the problem of wasting time(More)
