Aluminum electrolytic cell voltage signal is the most important real-time data in the process of aluminum electrolysis. Under normal circumstances, the traditional LMD decomposition of the original voltage signal containing noise in the aluminum electrolytic cell will produce a large error and affect the diagnosis of the failure of the aluminum electrolytic cell. In this paper, an improved LMD decomposition...
This paper presents a control system of feeding paper in fruit-bag machine based on fuzzy parameter self-adaptive PID. First, it put forward the mathematical model of control system according to the design characters. Then, it analyzed the structure and rules of controller and estimated the fuzzy parameters of PID by evaluating fuzzy relations equation. By the theoretical analysis and system??s experimental...
The problem of tag contention is a major obstacle for performance improvement of RFID system. Contention control strategy can increase throughput of the finite shared wireless channel and thus accelerate the identification of large RFID tag populations. This paper presents a novel contention control strategy, interleave binary tree algorithm, that combines the advantages of Aloha algorithm and tree...
In this paper, the E-field distribution in a waveguide partly filled with t issue-simulating liquid at mobile communications frequencies is presented. For the E-field probes calibration in the tissue-simulating liquid, a standing open rectangular waveguide partly filled with tissue-simulating liquid is used in which the E-field can be calculated analytically from input power measurements. It is desirable...
