Introduction Recently I have seen many examples of a type of architecture that was new to me. Half of the demonstrations at OOPSLA’97 were examples of this architecture. I have not found any descriptions of this architecture, yet the number of systems that I have seen indicates that it is widely used. This architecture leads to extremely extensible systems, often ones that can be extended by no...

Digital libraries are fast expanding into the role of independent educational entities that aspire not only to complementing traditional classroom teaching, but also allow open electronic learning for distance and continued education. These multifaceted roles can be realized only if the course content and the related content management system are versatile enough to be captured into any individ...

SPSPR (S-Strategy, P-Business Processes, S-ICT Services, P-ICT Processes, R-ICT Resources) is a layered framework that is used to represent the relationship between business management and ICT management in the context of cloud computing. This research article applies the advanced object-oriented techniques and develops a fundamental object-oriented SPSPR-Model including four basic design patte...

Robot localization and mapping algorithms commonly represent the world as a static map. In reality, human environments consist of many movable objects like doors, chairs and tables. Recognizing that such environment often have a large number of instances of a small number of types of objects, we propose an alternative approach, Model-Instance Object Mapping that reasons about the models of obje...

For economic reasons aircraft performance is pushed towards its physical limitations. As far as ight control is concerned, it is required to thoroughly investigate ight system dynamics, i.e., the interaction between ight dynamics (including airframe structural exibility) and ight systems (consisting of actuators/motivators and controls). Computational handling of this interaction is best taken ...

A system with a Dynamic Object Model allows the types of objects to change at runtime. This includes adding new types, changing existing ones, and changing the relationships between types. Taken together, all types and their relationships form a domain-specific model. Underlying such a dynamic object model is a framework that acts much like a domain-specific modeling language. Dynamic Object Mo...
