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...

Figure 1: The manipulation of nutrient enrichment along elevational gradients. We considered three components of bacterial biodiversity: alpha, beta and gamma diversity29. Alpha diversity referred to the local bacterial species richness in each microcosm. Beta diversity referred to the community differentia...
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 ...

Derivation of a potential temperature that is conserved in saturated adiabatic ascent eliminates the need to include latent heat source terms in the time-dependent thermodynamic equation. An analogous variable that is conserved for a cloud in adiabatic ascent can be determined that relates temperature ...
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 ...
The effect of temperature on the photosynthetic rate was analyzed using a thermodynamic model (Alexandrov and Yamagata 2007). Here, the gross photosynthetic rate (GP), is treated as a latent variable, which is assumed to be equal to the sum of the net photosynthetic rate (NP) and the dark...
