Software systems today need to dynamically self-adapt against dynamic requirement changes. In this paper we describe RAMSES a reflective middleware whose aim consists of consistently evolving software systems against runtime changes. This middleware provides the ability to change both structure and behavior for the base-level system at run-time by using its design information. The meta-level is...

abstract background and aim: one of the major problems with resin composite restorations is the weakness of bonding between the new and aged composites. since appropriate micromechanical retention is necessary for the repair of aged resin composite restorations, the level of surface roughness after sandblasting can be influential in this regard. considering the diverse composition of available ...

As applications become larger and more complex, it is frequently the case that system components require varying models of computation. The use of different computational models is not well supported by standard object-oriented mechanisms and systems. Typical mechanisms implicitly encapsulate meta-level (i.e., computational) semantics along with the base-level (i.e., domain) behaviour. Objects ...
