This specification establishes the performance requirements for surge suppressors used on shipboard ac power circuits that may consist of a single circuit element or may be a hybrid device using several suppression devices. The surge suppressor shall be a protective device for limiting voltage tr...

1.1 This practice covers a uniform protocol for evaluating the performance of systems used to detect releases of regulated substances from underground storage tank systems or facilities. This practice applies to users, manufacturers, vendors, government regulators, and others using or concerned w...

Proportion resonant(PR) controllers are able to achieve zero steady-state error for AC input signals and are widely used for simplifying control systems in the stationary reference frame. However, power decoupling in the stationary reference frame with a PR controller has not been investigated thoro...

Automatic gain control (AGC) has been used in many applications. The key features of AGC, including a steady state output and static/dynamic timing response, depend mainly on key parameters such as the reference and the filter coefficients. A simple model developed to describe AGC systems based on s...

A novel and efficient method for decomposing a signal into a set of intrinsic mode functions (IMFs) and a trend is proposed. Unlike the original empirical mode decomposition (EMD), which uses spline fits to extract variations from the signal by separating the local mean from the fluctuations in the ...
