Curve Fitting

See a model fit

A natural cubic spline, refit live — the same kind of curve-fitting behind every model this practice builds.

Click to place a measurement. The curve refits every time.

State-Space Models

Multidomain state-space

Different physics, same governing form: $$\dot{x}(t) = Ax(t) + Bu(t), \quad y(t) = Cx(t) + Du(t)$$

u(t) R L C v_C i →

State: capacitor voltage v_C (V) and current i (A) — response to a 1 V step.

m k c x

State: displacement x (m) and velocity ẋ (m/s) — response to a 1 N step. Stiffer k → smaller steady-state x.

T_amb R C T

State: temperature T (°C), driven by heat flow through R — response to a 1°C ambient step.

Our Approach

  
Philosophy

  

    Nous Engineering treats complexity as something to eliminate, not
    manage. A model that's actually right tends to look deceptively simple
    once it's finished — the redundant terms are the first thing to go.
    That standard holds whether the system is electrical, mechanical,
    thermal, or structural, because the underlying discipline is the same.
