A wide range of animal species accumulate objects in, on, and/or around structures they build. Sometimes, these accumulations serve specific functions (e.g. structural or isolating features) are purely incidental, while in other cases the materials deliberately displayed to signalling purposes (extended phenotype signals). In this pilot study, we employed systematic situ observations and camera...

Preface Complex computer-based systems have become an essential part of our society. These complex systems are generally composed of a number of components that act concurrently and interact with each other and the environment of the system concerned. The complexity arises to a great extent from the many ways in which the components of the system can interact. Not surprisingly , means for the d...

In this research, behaviour of clayey soils under triaxial loading is studied using Neural Network. The models have been prepared to predict the stress-strain behaviour of remolded clays under undrained condition. The advantage of the model developed is that simple parameters such as physical characteristics of soils like water content, fine content, Atterberg limits and so on, are used to mode...

Choreographies and Contracts are important concepts in Service Oriented Computing. Choreographies are the description of the behaviour of a service system from a global point of view, while contracts are the description of the externally observable message-passing behaviour of a given service. Exploiting some of our previous results about choreography projection and contract refinement, we show...

The complex systems lying at the heart of ensemble engineering exhibit—and are perhaps even characterised by—emergent behaviour: behaviour that is not explicitly derived from the functional description of the components of the ensemble at the level of abstraction at which they are provided. A typical example from Artificial Life comprises an ensemble consisting of a flock of birds; the componen...

We consider a special correlation function in the isotropic spin-1 2 Heisenberg antiferromagnet. It is the probability of nding a ferromagnetic string of (adjacent) spins in the antiferromagnetic ground state. We give two diierent representations for this correlation function. Both of them are exact at any distance, but one becomes more eeective for the description of long distance behaviour, t...

in this paper, we introduce fractional order of a planar fractional prey-predator system with a nonmonotonic functional response and anti-predator behaviour such that the adult preys can attack vulnerable predators. we analyze the existence and stability of all possibleequilibria. numerical simulations reveal that anti-predator behaviour notonly makes the coexistence of the prey and predator po...

This paper proposes the notion of Specification-Carrying Code as an interaction mechanism for self-assembly of autonomous decentralised software components. Each autonomous software entity incorporates more information than its operational behaviour, and publishes more data than its signature. The idea is to provide separately, for each entity, a functional part implementing its behaviour the t...
