If the "Autosave" functionality is enabled in the configuration dialogue wxMaxima acts like mobile apps that backup the file every few minutes and save it on closing.
wxMaxima confuguration 대화 상자에서 '자동 저장' 기능을 활성화하면 wxMaxima는 몇 분마다 파일을 백업하고 닫을 때 저장하는 모바일 앱처럼 작동합니다.

Temperature effects_maturity
In the CEB-FIP Model Code 90 , maturity is a concept used to predict the rate at which concrete gains strength based on temperature and time. Eq. (2.1-87) is used to calculate the maturity-adjusted time t_T$ $ , which accounts for the effects of temperature on concrete's strength development. \( S=\int d^{4} x\left(\frac{R}{2 \kappa}\right) \) begin{eqation} S=\int d^{4} x\left(\frac{R}{2 \kappa}\right) end{equation} Definition of Equation (2.1-87): The maturity-adjusted time tTt_T tT is calculated as: tT=∫t0texp[QR(1T0−1T(τ))]dτt_T = \int_{t_0}^{t} \exp \left[ \frac{Q}{R} \left( \frac{1}{T_0} - \frac{1}{T(\tau)} \right) \right] d\tau tT=∫t0texp[RQ(T01−T(τ)1)]dτ$$ Where: tTt_T tT = maturity-adjusted time (in days) tt t = real elapsed time (in days) t0t_0 t0 = start time for the calculation (usually 0) QQ Q = activation energy for hydration process, typically around 33,500 J/mo...
