Abstract
This paper discusses the mathematical properties of a recently developed mathematical model of a direct contact membrane distillation system. The model consists of two-dimensional advection diffusion system coupled at the boundary. A semi-group framework is used to analyze the model. First, the infinitesimal generator operator and its properties are studied. Then, existence and uniqueness of the solutions are investigated using the theory of operators. Some regularity results of the solution are also established. A particular case showing the diagonal property of the principal operator is studied. However, based on this new partial differential model we formulated our problem of output tracking design for the parabolic distillation system. Using a partial boundary measurement, we first propose an extended state observer to estimate both system state and the disturbance. Then we design a servomechanism and thereafter an output feedback controller. Thus by some regularity for the reference signal and the disturbance vanish, we prove the exponential decay of the output tracking error. Moreover, we show the performance of the control strategy in presence of the measurement noise.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
