Abstract. The aim of this monograph is to present a comprehensive survey of results about existence, multiplicity, perturbation from symmetry and concentration phenomena for the quasi-linear elliptic equation nX i,j=1 Dx j (aij(x, u)Dx i u) + 1 2 nX i,j=1 Duaij(x, u)Dx i uDx j u = g(x, u) in Ω, where Ω is a smooth domain of Rn, n ≥ 1. Under natural assumptions on th

A Multi-Perspective Framework for Method Integration

The development of large and complex systems necessarily involves many people - each with their own perspective on the system, defined by their skills, responsibilities and expertise. This is particularly true for composite systems, that is, systems which deploy multiple component technologies. The intersections between perspectives however, are far from obvious because the knowledge within each is represented in different ways. Furthermore, because development may be carried out concurrently by those involved, different perspectives may be at different stages of elaboration, and may be subject to different development strategies. The problem of how to guide and organise systems development in this setting, we term the "multiple perspectives problem". This thesis focuses on the specification and design of software-based systems. In particular, it addresses the problem of method integration in this setting, which is viewed as an instance of the multiple perspectives problem. The thesis ..
