Technical report TR92-20. Workstations have been in use for more than a decade now. Although a network of workstations represents a large amount of aggregate computing power, there is a need for software that can harness this power for single, distributed applications. Enterprise is an...

Technical report TR98-01. In this paper we present a type system that combines inclusion and parametric polymorphism with behaviors (multi-methods) and precise function typing. Type declarations allow user-definable variance specification of type parameters and user-definable subtyping between...

Peters, Randal J., Ozsu, M. Tamer, Szafron, Duane, Lipka, Anna

Technical report TR93-01. The establishment of a formal object model provides a theoretical foundation to investigate other objectbase features such as query processing. In this report, we present an extensible uniform behavioral object query model for the TIGUKAT(*) object management system. ...

Technical report TR92-14. Object-oriented computing is influencing many areas of computer science including software engineering, user interfaces, operating systems, programming languages and database systems. The appeal of object-orientation is attributed to its higher levels of abstraction for...

Character behaviours in computer role-playing games have a significant impact on game-play, but are often difficult for story authors to implement and modify. Many computer games use custom scripts to control the behaviours of non-player characters (NPCs). Therefore, a story author must write...

Technical report TR96-02. Video modeling has become a topic of increasing interest in the area of multimedia research. One of the key aspects in the video medium is the temporal relationship between video frames. In this report1 we propose a tree based model for specifying spatial and temporal...

Technical report TR03-13. Parallel programming is seen as an effective technique to improve the performance of computationally-intensive programs. This is done at the cost of increasing the complexity of the program, since new issues must be addressed for a concurrent application. Parallel...
