Modelling responses to a smallpox epidemic taking into account uncertainty

Mathematical modelling of calcium signalling taking into account mechanical effects

Most of the calcium in the body is stored in bone. The rest is stored elsewhere, and calcium signalling is one of the most important mechanisms of information propagation in the body. Yet, many questions remain open. In this work, we initially consider the mathematical model proposed in Atri et al. [1]. Omitting diffusion, the model is a system of two nonlinear ordinary differential equations (...

A New Heuristic Algorithm for Time-cost Trade-off Problem Taking into Account Monetary Value

Time-cost trade-off is one of the most important subjects in project management and of interest to contractors. The goal of time-cost trade-off is sensivity analysis of project costs to changes in activity duration in order to obtain the best combination of activity duration decrease, in a way that the sum of project costs is minimized. In the heuristics presented in this area, time crashing is...

Taking Uncertainty Into Account. Bias Issues Arisingfiom Parameter Uncertainty in Risk Models

Taking into Account Interval (and Fuzzy) Uncertainty Can Lead to More Adequate Statistical Estimates

Traditional statistical data processing techniques (such as Least Squares) assume that we know the probability distributions of measurement errors. Often, we do not have full information about these distributions. In some cases, all we know is the bound of the measurement error; in such cases, we can use known interval data processing techniques. Sometimes, this bound is fuzzy; in such cases, w...
