Governor Report Template

Previous panel papers have described testing for NERC and WSCC compliance [A] and testing and tuning of governors for compliance and island-mode performance [B]. This paper presents experience with testing of gas turbine plants for NERC and WSCC compliance. Testing has been performed on older analog-electronic and new digital-electronic units. The level of detail used in modeling and model avai...

Summability with a Governor of Integral Order

Analysis of chaotic vibration in a hexagonal centrifugal governor system

In this paper, the periodic, quasi periodic and chaotic responses of rotational machines with a hexagonal centrifugal governor are studied. The external disturbance is assumed as a sinusoid effect. By using the forth order Rung-Kutta numerical integration method, bifurcation diagram, largest Lyapunov exponent and Lyapunov dimension are calculated and presented to detect the critical controlling...

A sense-able microRNA.

In this issue of Genes & Development, Drexel and colleagues (pp. 2042-2047) present a beautiful example of how microRNAs (miRNAs) can regulate tissue-specific gene expression in a biologically relevant setting. They found that miR-791 is expressed in only three types of carbon dioxide (CO2)-sensing neurons in Caenorhabditis elegans, and its primary function there seems to be repression of two t...
