The Low Latency Fault Tolerance (LLFT) system provides fault tolerance for distributed applications, using the leader-follower replication technique. The LLFT system provides application-transparent replication, with strong replica consistency, for applications that involve multiple interacting processes or threads. The LLFT system comprises a Low Latency Messaging Protocol, a Leader-Determined...

As more and more applications with dynamic files are introduced in peer-to-peer (P2P) systems, file consistency maintenance becomes important. In this paper, we propose a novel file consistency maintenance algorithm, called Update P ropagation Through Replica Chain (UPTReC), for decentralized and unstructured peer-to-peer (P2P) systems. UPTReC provides a probabilistically guaranteed file consis...

The Teens, Manga and Digitally Produced Replicas Project, which brings together archaeologically charged replicas, members of the ‘youth generation community’ manga cartoons, forms part PhD research at Institute Archaeology. broadly aims to address a need for increased access investment in understandings heritage teens with use 3D print replicas through driven active engagement object-based lea...

Content Delivery Networks (CDN) design entails the placement of server replicas to bring the content close to the users, together with an efficient and content aware request routing. In this paper we address the problem of dynamic replica placement to account for users demand variability while optimizing the costs paid by a CDN provider and the overall performance of the distributed replica ser...

Most of the frequent techniques in text mining are based on the arithmetic scrutiny of a idiom, either word or slogan. Arithmetical scrutiny of a term incidence captures the consequence of the term within a manuscript only. However, two provisos can have the similar regularity in their documents, but one term contributes more to the connotation of its sentences than the further term. Thus, the ...

We find a new solution of the renormalization group for the Potts model with ferromagnetic random valued coupling constants. The solution exhibits universality and broken replica symmetry. It is argued that the model reaches this universality class if the replica symmetry is broken initially. Otherwise the model stays with the replica symmetric renormalization group flow and reaches the fixed p...

Fault tolerance schemes for mobile agents to survive agent server crash failures are complex since developers normally have no control over remote agent servers. Some solutions modify the agent server platform, e.g. a replica of the mobile agent is injected into stable storage upon its arrival at an agent server. However in the event of an agent server crash the replica remains unavailable unti...
