Optimistically replicated systems provide highly available data even when communication between data replicas is unreliable or unavailable. The high availability comes at the cost...
Abstract. This paper presents a new approach to inverse consistent image registration. A uni-directional algorithm is developed using symmetric cost functionals and regularizers. I...

Signatures detect changes to the data objects. Numerous schemes a known, e.g., the popular hash based SHA-1 standard. We propose a nov scheme we call algebraic signatures. We use ...
