Complex adaptive systems (CAS) modeling has become a common tool to study the behavioral dynamics of agents in a broad range of disciplines from ecology to economics. Many modelers have studied structure’s importance for a system in equilibrium, while others study the effects of perturbations on system dynamics. There is a notable absence of work on the effects of agent interaction pathways on ...

Statistical physics has accustomed us to mathematical descriptions of systems with a large number of components. The thermodynamic properties of ideal gases were understood as early as the end of the 19th century, while those of solids were understood at the beginning of the 20th century. In both cases, two important properties make modeling easy: B These are systems in which all of the compone...

disconnects and defects in care – such as duplication, poor integration between services or avoidable adverse events – are costly to the health system and potentially harmful to patients and families. for patients living with multiple chronic conditions, such disconnects can be particularly detrimental. lean is an approach to optimizing value by reducing waste (eg, duplication and defects) and ...

Basic evidences on non-profit making and other forms of benevolent-based organizations reveal a rough partition of members between some pure consumers of the public good (free-riders) and benevolent individuals (cooperators). We study the relationship between the community size and the level of cooperation in a simple model where the utility of joining the community is proportional to its size....

We argue that socio-technical systems can be understood as complex adaptive systems, that is, systems containing component sub-systems interacting such that they co-evolve This viewpoint may allow us to understand more clearly the factors that underlie the complexities of socio-technical systems, and allows for a new approach to systems design predicated on unpredictable adaptive processes. Sys...

Macrobehaviors in complex adaptive systems are highlevel behaviors that arise from a combination of low-level interactions and characteristics of individuals. Over time, individuals participating in these complex systems make choices that influence the behavior of other individuals. These types of interactions are present in both human and computational systems. For example, complex interactive...

This paper, will explore potential contributions from the study of complexity theory to the area of pervasiveness of information systems. It offers insights for enriching traditional approaches of information system design that could lead to better framework for supporting pervasiveness in complex environment. Complex environment makes new problems for pervasiveness because it is hard for users...

A flexible-joint robot manipulator is a complex system because it is nonlinear, multivariable, highly coupled along with joint flexibility and uncertainty. To overcome flexibility, several methods have been proposed based on flexible model. This paper presents a novel method for controlling flexible-joint robot manipulators. A novel control law is presented by compensating flexibility to form a...
