The incorrectness of function grading in value engineering has been an essential problem for decades. This paper proposes a new method, where the functions under consideration are ranked in queue according to their importance and then graded quantitatively. By using this method, the reviewers are...
Objective: In addition to pH regulation, Na + /H + exchange (NHE) has been shown to facilitate cell growth and proliferation. However, the effects of long-term inhibition of Na + /H + exchange on cardiac structural and functional remodeling post myocardial infarction (MI) are still controversial....
This paper reports results of research on the stability of a hydraulic servo position system using generalization pulse code modulation (GPCM) and common on/off valves for hydraulic servo control. The describing function was first used to analyze the system's stability, and based on the nonlinear...
