In this paper, we propose four architectures for intrusion-tolerant database systems. While traditional secure database systems rely on prevention controls, an intrusion-tolerant ...
We explore the execution of queries with client-site userdefined functions (UDFs). Many UDFs can only be executed at the client site, for reasons of scalability, security, confide...
We present a method for hierarchical data approximation using curved quadratic simplicial elements for domain decomposition. Scientific data defined over two- or three-dimensional ...
Accurate noise level estimation is essential to assure good performance of noise reduction filters. Noise contaminating raw images is typically modeled as additive white and Gauss...
