Work Assignment Planning and Numerical Implementation (systems with single state variable)

4 Março 2026, 13:30 • Rafael Neto Henriques

The session began with a comprehensive review of the work plan for the practical-laboratory classes, focusing on the essential deadlines for each phase of the course assignment. The technical focus then shifted to numerical simulation, specifically explaining how to implement differential equations for systems. The Euler method was introduced as a foundational numerical technique to solve these equations over discrete time intervals. The class concluded with a practical exercise where students implemented this method to simulate dynamic system responses of system with a single state variable.

Feedback Formulation and Physiological Control

4 Março 2026, 10:00 • Rafael Neto Henriques

The first part of the lecture illustrated how feedback between two mutually causal variables can be formulated using differential equations, using Bolie’s minimal model of the Glucose-Insulin system as a primary application. This model demonstrates how principles of mutual causal feedback (e.g., insulin's effect on glucose and vice versa) are combined with inherent feedback terms to describe system dynamics. The second part of the class introduced the broader concept of control in physiological systems, focusing on how various regulatory mechanisms - from intracellular processes to hierarchical organ systems - ensure homeostasis within the human organism.

Combination of simple dynamic models and introduction to feedback foundation - inherent feedback

3 Março 2026, 11:00 • Rafael Neto Henriques

The first part of this lecture provided a review of simple models for dynamic systems with a single state variable, followed by an example of how these basic units are combined to represent more complex physiological structures. The second part introduced fundamental feedback concepts, starting with causal feedback loops in two-state variable systems where mutual causality ensures regulation. Finally, the concept of inherent feedback was explored, illustrating how regulatory effects can be naturally embedded within the differential equations of simple, single-state variable systems even without explicit physical feedback links.
