In this article, we propose an original method for providing fault tolerance in multi-agent systems through replication. Our method focuses on building an automatic, adaptive and predictive replication policy to solve the resource allocation problem of determining where agents must be replicated to minimize the impact of failures. This policy is determined by taking into account the criticality...

The exploration of quantitative variation in complex traits such as gene expression and drug response in human populations has become one of the major priorities for medical genetics. The International HapMap Project provides a key resource of genotypic data on human lymphoblastoid cell lines derived from four major world populations of European, African, Chinese and Japanese ancestry for resea...

Influenced by generative and intentional learning methodologies, the Web Resource Collaboration Center (WRCC) was developed to provide a structure and forum for lifelong learning activities by empowering learners to build their own Web-based knowledge bases and support systems. The WRCC – written entirely in Perl – enables learners to collaboratively build comprehensive knowledge base systems t...

Multiple applications executing concurrently on a multicore system interfere with each other at different shared resources such as main memory and shared caches. Such inter-application interference, if uncontrolled, results in high system performance degradation and unpredictable application slowdowns. While previous work has proposed application-aware memory scheduling as a solution to mitigat...

In this paper, we present a dynamic bandwidth allocation strategy based on renegotiation. This strategy consists in exploring the unused resources in the network, allocating them to flows whose required bandwidth is greater than the one that was attributed to them at call admission time. These applications, which are non delay sensitive, can be admitted by the CAC (Call Admission Control) with ...

The purpose of the online resource presented here, POPcorn (Project Portal for corn), is to enhance accessibility of maize genetic and genomic resources for plant biologists. Currently, many online locations are difficult to find, some are best searched independently, and individual project websites often degrade over time-sometimes disappearing entirely. The POPcorn site makes available (1) a ...

In recent years there is a need for a security infrastructure for our ubiquitous digital life without using Public key infrastructure and shared session key cryptography algorithms. Since the system scales up, the peer to peer approach is attractive to Distributed Computing Environment due to increase in large amount of resources. The resources in such environment possess different characterist...

BACKGROUND Lifelines is a prospective population-based cohort study investigating the biological, behavioral and environmental determinants of healthy ageing among 167,729 participants from the North East region of the Netherlands. The collection and geocoding of (history of) home and work addresses allows linkage of individual-level health data to detailed exposure data. We describe the reason...

In shared resource environments, usage data is necessary to identify utilization of the infrastructure by users. Many cloud platforms recently started to collect measurements for use of resources that can be applied to billing and monitoring. Understanding utilization and performance through these measurements is crucial in the infrastructure in order to provide better cloud provisioning, syste...
