Isotonicity

Isotonicity

 

relative constancy of osmotic pressure in the fluid media and tissues of the body, a result of the maintenance at a given level of the concentrations of electrolytes, proteins, and other substances.

Isotonicity is one of the body’s most important physiological constants, which are ensured by mechanisms of self-regulation. Deviation of osmotic pressure from the normal physiological level (≈76–0.81 meganewtons per sq m, or 7.6–8.1 atmospheres) leads to the disruption of metabolic processes between the blood and the interstitial fluid.

The study guide does not contain written information about isotonicity; however, students can complete a rendering of this state on the second page of the study guide.
As demonstrated in literature [6], isotonicity is a sufficient and necessary condition for Bellman-Ford and Dijkstra's algorithm to find minimum weight paths, so routing protocols based on Bellman-Ford and Dijkstra's algorithm may not find minimum weight path between a pair of nodes when using BP2BG as routing metric.
To ensure the validity of the DEA model specification, an isotonicity test (according to Golany and Roll (1989)) was conducted.
Using Affine Arithmetic the bounds on the worst case circuit behavior are calculated and the global minimum of sizing problem is determined due to inclusion isotonicity. Beside analog domain, Affine Arithmetic models can also be used in Digital Signal Processing (DSP) applications to represent errors introduced by calculations in floating-point arithmetic [34, 35].
To ensure the validity of the DEA model specification, an isotonicity test (Avkiran, 1999) was conducted; the test involves the calculation of all inter-correlations between inputs and outputs for identifying whether increasing amounts of inputs lead to greater outputs.
