Chaos and complexity in measles models: a comparative numerical study.

Development of Fluency, Accuracy, and Complexity in Productive Skills of EFL learners across Gender and Proficiency: A Chaos Complexity Approach

This study was an attempt to investigate the developmental rate of fluency, accuracy and complexity among 12 EFL learners within the framework of chaos complexity theory. To carry out this study, 6 female and 6 male participants in two levels of proficiency (pre-and upper-intermediate) were put in two classes taught by the same teacher and following the same course. Every two months (for a peri...

Chaos/Complexity Theory and Education

Sciences exist to demonstrate the fundamental order underlying nature. Chaos/complexity theory is a novel and amazing field of scientific inquiry. Notions of our everyday experiences are somehow in connection to the laws of nature through chaos/complexity theory’s concerns with the relationships between simplicity and complexity, between orderliness and randomness (Retrieved from http://www.inc...

A MULTI-OBJECTIVE OPTIMIZATION MODEL FOR PROJECT PORTFOLIO SELECTION CONSIDERING AGGREGATE COMPLEXITY: A CASE STUDY

Existing project selection models do not consider the complexity of projects as a selection criterion, while their complexity may prolong the project duration and even result in its failure. In addition, existing models cannot formulate the aggregate complexity of the selected projects. The aggregated complexity is not always equal to summation of complexity of projects because of possible syne...

Discretization of a fractional order ratio-dependent functional response predator-prey model, bifurcation and chaos

This paper deals with a ratio-dependent functional response predator-prey model with a fractional order derivative. The ratio-dependent models are very interesting, since they expose neither the paradox of enrichment nor the biological control paradox. We study the local stability of equilibria of the original system and its discretized counterpart. We show that the discretized system, which is...
