AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The oligomerization of activated D- and L- and racemic guanosine-5'-phosphoro-2-methylimidazole on short templates contg. D- and L-deoxycytidylate has been studied. Results obtained with D-oligo(dC)s as templates are similar to those previously reported fo ...
A review and discussion, with 42 refs. Base pairing in p-RNA (b-D-ribopyranosyl-(4'->2')-oligonucleotides) is not only stronger than in DNA and RNA, but also more selective in the sense that it is strictly confined to the Watson-Crick mode. Homopurine sequ ...
This dissertation studies the problems to solve in order to use the invocation paradigm to express replicated object communication in fault-tolerant distributed systems. The ultimate goal is to define abstractions which achieve replication encapsulation, i ...
This paper presents the semi-passive replication technique -- a variant of passive replication -- that can be implemented in the asynchronous system model without requiring a membership service to agree on a primary. Passive replication is a popular replic ...
Replication is a key mechanism for developing fault-tolerant and highly available applications. In this paper, we present a replication framework for replicating CORBA objects, that combines the active and passive replication techniques. We show how we hav ...
Replication is an area of interest to both distributed systems and databases. The solutions developed from these two perspectives are conceptually similar but differ in many aspects: model, assumptions, mechanisms, guarantees provided, and implementation. ...
Replication is a powerful technique for increasing availability of a distributed service. Algorithms for replicating distributed services do however face a dilemma: they should be (1) efficient (low latency), while (2) ensuring consistency of the replicas, ...
This paper presents the semi-passive replication technique -- a variant of passive replication -- that can be implemented in the asynchronous system model without requiring agreement on a primary (usually done using a membership service). Passive replicati ...
A distributed algorithm comprises a collection of sequential-code entities, which are spread over different computers connected to a network. The process of designing a distributed algorithm is influenced by the assumptions we make on the computational env ...
A well accepted technique to ensure reliability in a distributed system is to replicate every object which performs critical processing. However, it is not easy to achieve replication, i.e to enable a replicated object to communicate with other objects, ju ...
