The model is based on the hypothesis that competition between cropping andchewing regulates instantaneous intake rate in response to changes in the size of bites obtained by the forager.

The grazing behavior,intake rate and diet digestibility of Boer goats grazing in sowed ryegrass pasture in a replicated 2×2 factorial experiment were studied.

Diagnosis method of instantaneous frequency for rotor impact-rub fault of aeroengine;

Ultrasonic signal process method based on instantaneous frequency;

Study of analysis of instantaneous frequency in partial wave method;

Instantaneous power maxima and power spectrum maxima analysis of second heart sounds signals;

The essence of the instantaneous power control in internal mixer is to control the viscosity of mixing material.

This paper presents the mathematical model of the three-level voltage source PWM rectifier and deduces the relationships between instantaneous power and the vectors of the three-level rectifier from the theory of instantaneous reactive power.

Comparative analysis of the instantaneous efficiency about two types of solar collector

Results show that mass area ratio (MAR) is a primary factor to average daily efficiency and instantaneous efficiency curve of tubular solar water heaters is not straight line.
