Incorporating the effect of the photon spectrum on biomass accumulation of lettuce using a dynamic growth model.

Cultivation studies in specialty crop optimization utilize models to estimate the fresh and dry mass yield. However, the spectral distribution and photon flux density affect plant photosynthetic rate and morphology, which is usually not incorporated in plant growth models. In this study, using data for indoor-grown lettuce () cultivated under different light spectra, a mathematical model that incorporates these effects is presented.

Comparing the mathematical models of Lighthill to the performance of a biomimetic fish.

The mathematical models for the performance of aquatic animals developed by M Lighthill are compared with the experimental performance of a biomimetic fish. The equations developed by Lighthill are evaluated at steady-state conditions. Equilibrium velocity and mechanical efficiency are calculated using Lighthill's mathematical model and compared with experimental results.
