Technical report TR98-02. In this paper we present a model that supports a clean separation between the concepts of interface, implementation, and representation. We present several problems that are difficult to solve in the absence of such separation and describe how the proposed model can be...

Technical report TR03-14. Identifying the destination or localization of proteins is key to understanding their function and facilitating their purification. A number of existing computational prediction methods are based on sequence analysis. However, these methods are limited in scope, accuracy...

Technical report TR93-04. The Enterprise programming environment supports the development of applications that run concurrently on a network of workstations. This paper describes the object-oriented components of Enterprise, implemented in Smalltalk-80, and their seamless integration with ...

Technical report TR03-05. Modern sequencing technology now permits the sequencing of entire genomes, leading to thousands of new gene sequences in need of detailed annotation. It is too time consuming to predict the properties of each protein sequence manually and to organize the results of many...

Technical report TR95-25. Declarative query languages are an important feature of database management systems and have played an important role in their success. As database management technology enters the multimedia information system area, the availability of special-purpose query languages...

The traditional approach to implementing interactions between a player character (PC) and objects in computer games is to write scripts in a procedural scripting language. These scripts are usually so complex that they must be written by a computer programmer rather than by the author of the game...

Technical report TR04-05. Recently, some researchers have argued that generative design patterns (GDPs) can leverage the obvious design re-use that characterizes traditional design patterns into code re-use. This paper provides additional evidence that GDPs are both useful and productive. ...

Technical report TR96-05. In this paper we consider various spatial relationships that are of general interest for retrieving data from multimedia databases. We present a unified representation of spatial objects for both topological and directional relations. Such a representation is based on...

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...
