MODELING DAHLIA `ROYAL DAHLIETTA YELLOW' TEMPERATURE DEPENDENT DEVELOPMENT RATE

Mathematical Modeling of the Temperature-Dependent Growth of Living Systems

In this investigation a non-equilibrium thermodynamic model of the temperature dependent biological growth of a living systems has been analyzed. The results are derived on the basis of Gompertzian growth equation. In this model, we have considered the temperature dependent growth rate and development parameter. The non-equilibrium thermodynamic model is also considered for exploring the variat...

Modeling Temperature-Dependent Development of Glyphodes pyloalis (Lepidoptera: Pyralidae)

Development of Glyphodes pyloalis Walker was studied under laboratory conditions at constant temperatures of 12, 16, 20, 24, 28, 30, 32, and 36 °C. No development occurred at 36 °C. Although eggs hatched at 12 ºC, no larvae were capable of developing to adult stage. At 16 ºC, survival rate was low (4%) and prepupal stage lasted 101.68 ± 11.03 d. Larvae completed development through six stadia a...

Modeling Rate-dependent Hysteresis in Piezoelectric Actuator

Hysteresis of a piezoelectric actuator is ratedependent. Most hysteresis models are based on elementary rate-independent operators and are not suitable for modeling actuator behavior across a wide frequency band. This work proposes a rate-dependent modified PrandtlIshlinskii (PI) operator to account for the hysteresis of a piezoelectric actuator at varying frequency. We have shown experimentall...

A synthesis of the temperature dependent development rate for the obliquebanded leafroller, Choristoneura rosaceana

The obliquebanded leafroller, Choristoneura rosaceana (Harris) (Lepidoptera: Tortricidae), is a serious pest of apples and other tree crops throughout North America. A review of temperature dependent development and models show that five different lower thresholds for development are published and used as the basis of heat-driven phenology models. We present a small lab data set of C. rosaceana...
