The pheromone trail decay coefficient
([rho]) and pheromone amount ([phi]) have an important impact on the performance of ACO (Mehdi, Nasser, Mohammad, 2009).
i] [member of] [0, 1] is the decay coefficient
of i's emotion intensity (see Section 2.
The major factors in predicting the service life of concrete structures exposed to chloride environment are chloride content at the surface of the concrete, critical chloride content for corrosion of reinforcing steel, the diffusion coefficient, and diffusion decay coefficient
of chloride ions.
d] is the decay coefficient

From the kinetics fitting of the DOC temporal variation in Figure 1 b, the global decay coefficient

2] concentration data thereby linearizing the exponential decay curves for each room and then perform linear regression to identify the decay coefficient
(which is the slope of the transformed decay line) for each room.
This is contrary to what is normal where yield coefficient must be positive and decay coefficient
negative based on the model equation.
S] have been evaluated from the Lineweaver and Burk, double reciprocal plot, the decay coefficient
d] is a damage decay coefficient
