Academic Color Generation in Morpho Wings and Possible Replication Methods Structural colors have special properties that differ from colors produced by pigments. These include intensity patterns that change under different orientations and brilliant sparkling or glistening on the surface.
Academic Hill Model Simulation and Functional Electrical Stimulation While some have characterized the wrist as a second order system, the focus here is fitting a more complex fourth order model that accurately represents observed responses and muscle activity [1].
Academic Improving Brain Computer Interface Prediction by Measuring Eye Position and Focus Eye tracking devices allow patients with locked-in syndrome to communicate by tracking eye movement through infrared sensing. Can we use this in conjunction with BCIs to improve accuracy?
Academic Brain-Computer Interface: Motor Neuron Simulation Movements of the human body have been shown to correlate to neurons in the motor cortex of the brain and spinal cord.
Academic Simple State Space Model of a Pendulum This is the first post of a series that will build on simple pendulum dynamics to investigate different control laws and how model uncertainty affects the linear model approximation. Pendulum Model We will start by deriving the equations of motion for the simple pendulum shown below. The mass $m$ is
Academic Feedback Linearization - Its Performance and Limitations The goal is to design a feedback control law that perfectly cancels the nonlinear term in the pendulum dynamics. For this simple example, the derivation is straightforward and the performance difference is easily observed.
Academic Testing Full State Feedback Controller on Nonlinear Pendulum Dynamics We'll observe the response of a simple nonlinear pendulum by using a control law derived from linear analysis and test its performance.
Academic Simple Inverted Pendulum: Linear State Feedback Control We will start with that linear model and introduce a control $u$ proportional to the torque at the attachment point.
