Technical report TR01-03. In this paper, we present a new Content-Based Image Retrieval (CBIR) approach which is based on cluster analysis. A distinguishing aspect of CBIR is that it relies on a visual content representation (metadata) of the images. In order to produce such metadata, we propose...

Lee, Yooshin, Pu, Calton, Liu, Ling

Technical report TR96-10. We propose a query mediation framework to support customizable information gathering across heterogeneous and autonomous information sources. Instead of an integrated (and static) global schema, we propose an adaptive approach to interoperability which allows information...

Nascimento, Mario, Coman, Alexandru, Sander, Joerg

Technical report TR06-24. Wireless sensor networks have received much attention recently. Given their autonomy, flexibility and large range of functionality, they can be used as an effective and discrete means for monitoring data in many domains. Typically the network autonomy implies a limited...

Oliveira, Stanley, Zaiane, Osmar

Technical report TR03-15. In this paper, we address the problem of protecting some sensitive knowledge in transactional databases. The challenge is on protecting actionable knowledge for strategic decisions, but at the same time not losing the great benefit of association rule mining. To...

Goralwalla, Iqbal, Ozsu, M. Tamer, Tansel, Abdullah

Technical report TR94-15. In this paper we describe an implementation of a temporal relational database management system based on attribute timestamping. For this purpose we modify an existing software which supports set-valued attributes. The algebraic language of the system includes...

Szafron, Duane, Schaeffer, Jonathan

Technical report TR94-03. The growth of commercial and academic interest in parallel and distributed computing during the past fifteen years has been accompanied by a corresponding increase in the number of available parallel programming systems (PPS). However, little work has been done to...

Lin, Shu

Technical report TR00-04. Image similarity search is employed to retrieve similar images from a database. Colour features, particularly colour histograms, are extensively utilized to compute the image similarity. This thesis presents a multi-scale representation of image colour histograms that...

Munoz, Adriana

Technical report TR94-01. Objectbase Management Systems are expected to serve data management needs of a wide range of application domains with possibly different query optimization requirements, creating the need of extensibility in the query optimizer to be able to handle the diversity of those...

Zaiane, Osmar, Ammoura, Ayman

Technical report TR00-17. A system, DIVE-ON, was developed for visualizing and interacting with data from distributed data warehouses in an immersed virtual reality environment called a CAVE. The system provides navigation operations, OLAP manipulations, and data selection and filtering...

Cai, Zhipeng, Lin, Guohui, Want, Lusheng, Chen, Zhi-Zhong

Technical report TR08-06. The Capacitated Multicast Tree Routing Problem is considered, in which only a limited number of destination nodes are allowed to receive data in one routing tree and multiple routing trees are needed to send data from the source node to all destination nodes. The goal...
