In this work, an investigation has been made in to the performance of latent variable MPC (LV-MPC) in the specific application of reactor temperature control of an exothermic batch process. The paper analyzes the LV-MPC control law derivation and its performance within a batch application. The...
Latentqh=100 LMTDh=40−10ln40/10 =121.6°F Thus, WLMTD=1404018.2+10021.6 =20.5°F 3. If the T plot vs Q plot is curved, a linear approximation can be constructed for an LMTD calculation instead of using the divided segment approach 9.10.7.5 Approach (Δt2) The Approach is an econo...
We define as a quasi-order parameter the absolute average latent variable z, which enables us to predict the critical temperature. One can define a latent susceptibility and use it to quantify the value of the critical temperature Tc(L) at different lattice sizes and that these values suffer ...
The present study explored the association between temperature and both the transmissibility and the severity of COVID-19 from early 2020 to early 2021. We used the effective reproduction number(Rt), defined as the mean number of secondary cases generated by a single primary case, to quantify th...
In the background of increasing depth of metal mining, the issue of airflow temperature field during the construction of ultra-deep shaft is very important, in view of the fact that there is still very little research related to this content at home and
However, these physical processes exhibit weaker feedback with humidex heatwave variability across the two distinct modes, indicating the complexity of these interactions involving intensified cloud cover, surface humidity, and latent heat release due to significant atmospheric moisture injected into the ...
Currently, the temperature reference is the International Temperature Scale of 1990 (ITS-90), described in Preston-Thomas (1990). It consists of 17 defined fixed temperature points within the range of 0.65–1358 K, which are mostly defined as triple points and freezing points of certain ...

This method is known as the partial least squares approach to structural equation modelling and allows for the estimation of complex cause-effect relationship models with latent variables47, which was especially suitable for our experimental data with strong environmental gradients. Five latent variables ...
