Fig. 1. Phase portrait of System (1) with a constant dilution rate u(t) = D ∈ (µ(s in ), µ(¯ s)) (case ii of Proposition 1)
Fig. 2. How to choose D in one region (see Section V-A). A, thin lines: one can choose any D ∈ (D(y), D(y)); dashed lines: it is impossible to fulfill Conditions (5-6), given that D(y) > D(y)); B: ψ(y) represents the lower bound for y (limit case).
Fig. 3. Trajectories (magenta lines) with Control law (4) under uncertain mea- mea-surements (A2) for various initial conditions in the phase portrait
Fig. 5. Trajectories with Control law (4) when Conditions (5) or (6) are not fulfilled

AM2 model [1] to integrate SMP production and degradation. The mass balance equations are proposed in considering a new reaction network taking into account certain assumptions

Perspectives of this work include (i) model extension to constant flux and variable TMP filtration and, its validation using other experimental informative data, where

unconstrained planner would set monopoly distortions to zero, so C would reach its highest possible value, (1 — a) /a, and the planner would have a greater incentive to choose

From a mathematical point of view, this problem can be formulated as a time optimal control problem with state and control constraints, where the control variable (T 1 , T 2 , ρ 1 , ρ

given initial conditions, the goal is to define a feeding policy in order to reach a given substrate concentration with a completely full reactor in a minimal amount of time),

Results of solving a matrix of factors determine the cost of restructuring unstable macroeconomic systems with a balanced growth rate.. Knowing the cost of optimal

In particular, the camera frame rate is relatively low (around 30Hz) and, in addition, vision data processing can take a significant amount of time, espe- cially on small UAVs

We have solved the problem of rendering globally asymp- totically stable positive equilibrium points of a model of chemostat with a growth function of Haldane type, the
