Modules

functions module

Unit conversion and mathematical operation functions.

Mathematical Formulation:

1. Temperature Conversions: a) Kelvin to Celsius:

   \[T_{C} = T_{K} - 273.15\]

   where: - \(T_{C}\) is temperature in Celsius - \(T_{K}\) is temperature in Kelvin

   2. Celsius to Kelvin:

      \[T_{K} = T_{C} + 273.15\]

2. Mathematical Operations: a) Multiplication by Constant:

   \[y = x \cdot c\]

   where \(c\) is the constant factor

   2. Regularization:

      \[y = \max(x, l)\]

      where \(l\) is the lower limit

   3. Addition:

      \[y = \sum_{i=1}^{n} f_i(x_i)\]

      where \(f_i\) are conversion functions

   4. Multiplication:

      \[y = \prod_{i=1}^{n} f_i(x_i)\]

   5. Integration:

      \[y(t) = y(t-\Delta t) + f(x(t)) \cdot \Delta t\]

      where: - \(y(t)\) is the integrated value at time t - \(\Delta t\) is the time step - \(f(x(t))\) is the conversion function
