A Study of Image Indexing Techniques for Multimedia Database Systems
1995
Niu, Youping, Ozsu, M. Tamer, Li, Xiaobo
Technical report TR95-19. The role of indexing in query optimization is well-understood in the database community. Indexes enable efficient access to a subset of a database. There have been many studies on indexing within the context of relational database management systems (RDBMS). The most...

Technical report TR95-13. In this work, we present a uniform behavioral temporal object model which includes a rich and extensible set of types and behaviors to support various notions of time. Our temporal model supports the continuous and discrete domains of time. It also supports various...

Assessing Computational Thinking and Data Literacy: Designing the Callysto Computational Thinking Test (CCTt)
Download2019-01-01
Cutumisu, Maria, Adams, Cathy, Yuen, Connie, Hackman, Leah, Lu, Chang, Samuel, Mark, Chu, Byron
The Callysto Project is a collaborative project by Cybera and the Pacific Institute for Mathematical Sciences (PIMS), with funding from the Government of Canada. It involves the development and assessment of modules that promote data literacy and computational thinking. Using the Jupyter notebook...

Enrollment in Computing Science university programs is at a dangerously low level. A major reason for this is the general lack of interest in Computing Science by females. In this paper, we discuss our experience with using a computer game construction environment as a vehicle to encourage female...

Many computer games use custom scripts to control the ambient behaviors of non-player characters (NPCs). Therefore, a story writer must write fragments of computer code for the hundreds or thousands of NPCs in the game world. The challenge is to create entertaining and non-repetitive behaviors...

The unprecedented growth in numbers of children playing computer games has stimulated discussion and research regarding what, if any, educational value these games have for teaching and learning. The research on this topic has primarily focused on children as players of computer games rather than...

Li, John, Ozsu, M. Tamer, Szafron, Duane
Technical report TR96-12. Modeling moving objects has become a topic of increasing interest in the area of video databases. Two key aspects of such modeling are object spatial and temporal relationships. In this paper we introduce an innovative way to represent the trajectory of a single...

Technical report TR96-03. Most of the work in modeling time in information systems has concentrated on issues such as support for historical information and providing query facilities to manipulate such information. In doing so, some simplistic view of the underling nature of time has been...
