Adaptive hypermedia is a new area of research at the crossroads of hypermedia, adaptive systems and intelligent tutoring systems. The goals of this paper are to provide a brief overview of this area and to synthesize a generalized view of the organization of existing adaptive hypermedia systems. We discuss three important questions: why do we need adaptive hypermedia (AH), where can it be usefu...

1. INTRODUCTION The biological immune system is a robust, complex, adaptive system that defends the body from foreign pathogens. It is able to categorize all cells (or molecules) within the body as self or non-self substances. It does this with the help of a distributed task force that has the intelligence to take action from a local and also a global perspective using its network of chemical

Simulation techniques used to generate complex biological models are becoming promising research tools in oncology. Using a general Complex Adaptive Systems model that can be tailored to map various phenomena, here, we describe how this model applies to tumor growth. The multi-agent modeling environment is generated using Netlogo. The stochastic model consists of active objects including normal...

The growing interest in developing adaptive systems has led to numerous proposals for approaches aimed at supporting their development. Some approaches define adaptation mechanisms in terms of architectural design, consisting of concepts such as components, connectors and states. Other approaches are requirements-based, thus concerned with goals, tasks, contexts and preferences as concepts in t...

Overview The analysis of healthcare systems by considering them as complex adaptive systems (CAS) (Holland 2012) is a new and emerging field. The key idea is based on the inherent complexity of healthcare systems—in terms of the dynamics, nonlinearity, and unpredictability (Lipsitz 2012). While healthcare systems are naturally linked with CAS, there has always been a strong need for a compendiu...

After it is argued that philosophers of science have lost their interest in logic because they applied the wrong type of logics, examples are given of the forms of dynamic reasoning that are central for philosophy of science and epistemology. Adaptive logics are presented as a means to understand and explicate those forms of reasoning. All members of a specific (large) set of adaptive logics ar...

Adaptive hypermedia systems are spreading widely in these last years, but each application uses its own models and techniques. What I am studying is the possibility of developing a framework for user modelling in adaptive systems and in particular of creating a library of stereotypes for representing the different dimensions of the user models.
