The unusual self-organising behaviour of a glycosteroidal bolaphile.
نویسندگان
چکیده
In this communication we report on the self-organising properties of a novel asymmetric bolaphile composed of sugar and steroidal units. The material was found to exhibit unusual phase changes in that it formed a cubic phase upon heating, whereas upon cooling it formed a lamellar phase. This change in property was ascribed to kinetic versus thermodynamic behaviour at the phase transition to the liquid.

Engineering Self-Organising Emergent Systems with Simulation-based Scientific Analysis
The goal of engineering self-organising emergent systems is to acquire a macroscopic system behaviour solely from autonomous local activity and interaction. Due to the non-deterministic nature of such systems, it is hard to guarantee that the required macroscopic behaviour is achieved and maintained. Before even considering a self-organising emergent system in an industrial context, e.g. for Au...
متن کاملDesigning and controlling trustworthy self-organising systems
A self-organising system can arrange itself and modify its behaviour without receiving specific instructions to do so. Such systems are common in nature: flocks of birds responding to wind changes or a colony of ants structuring itself in response to a threat. But self-organisation is not only seen in nature – increasingly, artificial systems such as robots, mobile networks and software service...
متن کاملAnalysing an Evolved Robotic Behaviour Using a Biological Model of Collegial Decision Making
Evolutionary robotics can be a powerful tool in studies on the evolutionary origins of self-organising behaviours in biological systems. However, these studies are viable only when the behaviour of the evolved artificial system closely corresponds to the one observed in biology, as described by available models. In this paper, we compare the behaviour evolved in a robotic system with the colleg...
متن کاملA Generic Framework for the Engineering of Self-Adaptive and Self-Organising Systems
This paper provides a unifying view for the engineering of self-adaptive (SA) and self-organising (SO) systems. We first identify requirements for designing and building trustworthy self-adaptive and self-organising systems. Second, we propose a generic framework combining design-time and run-time features, which permit the definition and analysis at design-time of mechanisms that both ensure a...
متن کاملMothers’ Self-Efficacy Regarding Dietary Behaviour and Physical Activity of Preschool Children
Background Obesity constitutes a crucial health issue during preschool period and has an impact on children regardless their ethnic backgrounds. The purpose of the study was to examine the self-efficacy perceptions of mothers and potential differences and correlations with dietary behaviour and physical activity of their preschool children in Finland. Materials and Methods: The sample for this...
