Mathematical Modeling Of Color Perception Using Differential Equation, Siavash Pooretemad

Student Research Symposium

Color perception begins in the retina, where three cone types (L, M, S) detect light and initiate neural signals. These signals are processed by horizontal and bipolar cells to form opponent color channels: red-green (RG), yellow-blue (YB), and light-dark (LD). Perception is not solely based on physical input but also shaped by neural adaptation and context.

This project models color perception using a differential equation approach, simulating how color contrast and adaptation emerge from interactions between photoreceptors and lateral inhibition.

We hypothesize that a system of differential equations can model how retinal cone cells respond to and process light intensity, …

Dataset: Compositional Analysis And Hydrothermal Liquefaction Of A High-Ash Microalgae Biofilm, Jacob Watkins, Hamza Abdellaoui, Elise Barton, Clayton Lords, Ronald C. Sims

Biological Engineering Student Research

This dataset contains biochemical composition data and hydrothermal liquefaction (HTL) yield results for a high-ash microalgae biofilm which was cultivated in effluent from a mesophilic anaerobic digester using polyethylene rotating algae biofilm reactors (RABRs). These data were originally collected for use in a techno-economic analysis of biocrude, biodiesel, and bioplastic production from algae that was cultivated using RABRs for municipal wastewater reclamation.

Biochemical data for the microalgae biomass includes bulk protein, measured both using the Bradford protein assay and by multiplying total N; carbohydrate content, measured using a 3-methyl-2-benzothiazolinone hydrazone / dithiothreitol (MBTH/DTT) assay; total lipid content, measured using a …
