vices provide an important abstract layer on top of heterogeneous components (hardware and software) that take part into a grid environment. In this scenario, applications, like sc...
The application of information retrieval techniques in interactive environments requires systems capable of efficiently processing vague queries. To reach reasonable response tim...
We study the complexity of the dynamic partial sum problem in the cell-probe model. We give the model access to nondeterministic queries and prove that the problem remains hard. We...
The CenSSIS Image Database System is a scientific database that enables effective data management and collaboration to accelerate fundamental research. This paper describes the d...
We present a framework which allows the user to access and manipulate data uniformly, regardless of whether it resides in a database or in the file system (or in both). A key issu...
