duty cycle

[′düd·ē ‚sī·kəl]
(communications)
The product of the pulse duration and pulse repetition frequency of a pulse carrier, equal to the time per second that pulse power is applied. Also known as duty factor.
(electronics)
(engineering)
The time intervals devoted to starting, running, stopping, and idling when a device is used for intermittent duty.
The ratio of working time to total time for an intermittently operating device, usually expressed as a percent. Also known as duty factor.
(metallurgy)
The percentage of time that current flows in equipment over a specific period during electric resistance welding.
(nucleonics)
The fraction of time during which a pulsed accelerator beam is on target, usually expressed as a percent. Also known as duty factor.

duty cycle

(1) A machine's rated capacity to continuously perform work under normal conditions. It generally applies to mechanical devices such as printers, in which case it would indicate the number of pages that can be printed per month without a problem.

(2) The ratio of a device operating versus cooling down. An 80% duty cycle means that it is capable of running 80% of a specified time period and turned off for the remainder.

In MDA-SMAC protocol, data transmission can be repeated within a scheduling period, and the duty cycle of the micro-cycle can be adjusted according to buffer queue length.
Taking percent time on critical events such as braking, on torque curve operation (using 100% of available torque), idling and power take off also add to the attributes of the duty cycle - for example, a heavy haul application would have a lot more percent time on torque curve vs a light load application.
5(b) shows the PWM voltage and the current data acquired from the oscilloscope at a 200 Hz PWM frequency and 50% duty cycle.

The efficiency was found by measuring the DC output voltage, the output current, the DC input voltage, and the input current for each duty cycle for different frequencies.
We select a string as a chromosome to symbolize a solution to the energy-efficient duty cycle design problem.
The duty cycle could be set from 0.1% to 99.9% in 0.1% steps.
With increasing duty cycle, momentum in the trailing region is maintained to a higher degree since the tail is thicker.
In this paper we present a generic strategy for the duty cycle development for different types of NRMM vehicles.
The change in current dI as a function of the duty cycle can be measured theoretically, by simulation, and/or experimentally.
TRANSITION WITH PRE-CALCULATED STEADY-STATE DUTY CYCLE
the traffic, in our design we adapt the data traffic (i.e., the duty cycle) according to the energy available in the storage device; hence, the capability of adjusting the duty cycle of operation of the WSN node helps to extend the endurance of a batteryless operation.
