#### On None Approach to Equilibrium in Compartmental Systems

(University of Texas at Arlington, 1981-04)

The question of convergence of a solution of a compartmental system
to an equilibrium point, as t -> °°, is of considerable interest [1-6]. Although it was not explicitly stated, the remarks in [1] seem to suggest that ...

#### The Role of Nonreal Eigenvalues in the Identification of Cycles in a Compartmental System

(University of Texas at Arlington, 1983-11)

The paper concerns the relationship between the cycles in the graph of a compartmental system and the modes of the impulse response function associated
with an input-output experiment. Suppose that there is at least one ...

#### Stochastic Parameters in Compartmental Systems

(University of Texas at Arlington, 1980-05)

Let [see pdf for notation] denote the
probability that a particle in compartment j
will reach (or enter) compartment i. We present
several formulas for obtaining the [see pdf for
notation] in terms of the ...

#### Extension of Compartmental Parameters to Blocks of Compartments with Application to Lipoprotein Kinetics

(University of Texas at Arlington, 1983-02)

Suppose that the compartments of a compartmental model are separated into blocks (sets of compartments). In general, the blocks can not be regarded as compartments but it may be possible to construct a "condensation model," ...

#### Remarks on Bellman's Structural Identifiability

(University of Texas at Arlington, 1985-03)

This paper remarks on unidentifiable compartmental systems. Emphasis is placed on detecting properties of the system directly from the compartmental diagram without resort to complicated analysis. New concepts are introduced. ...

#### On Washout in Nonlinear Compartmental Systems

(University of Texas at Arlington, 1981-04)

Let x(t) be a solution of a compartmental system. If, for some compartment j, x (t) -> 0 as t -> °°, then we say that compartment
j washes out. We show that a compartment washes out if it always reaches (along a fixed ...

#### On Approach to Equilibrium in Nonlinear Compartmental Systems

(University of Texas at Arlington, 1981-02)

A closed compartmental system is a set of nonnegative interdependent functions,
[see pdf for notation]
such that their sum is constant. The functions can represent populations, masses or concentrations, depending on the ...

#### Structural Identification of Large Systems by Reduction to Subsystems: VLDL Triglycerides

(University of Texas at Arlington, 1982-05)

Experiments are performed for identification purposes,
i.e. to identify the values of unknown paprameters from data. In the event that one or more parameters can not be identified, the cause could be the result of a variety ...
