Impact of Duty Cycle Variation on WSNs [PDF]

open access: yes2009 3rd International Conference on New Technologies, Mobility and Security, 2009
Wireless Sensor Networks (WSNs) operate with varying duty cycles to meet their application-specific criteria such as the availability, reliability, and the life expectancy of the system. This variation in duty cycle consequently affects the system characteristics including the interference and collision of signals.

A Simple BATSE Measure of GRB Duty Cycle [PDF]

open access: yes, 2000
We introduce a definition of gamma-ray burst (GRB) duty cycle that describes the GRB's efficiency as an emitter; it is the GRB's average flux relative to the peak flux.
