You don't have to look far to become aware of the effect that service-oriented architecture (SOA) is having on software systems. Vendors are aggressively marketing hardware, software, tools, and services that support SOA implementation within organizations as diverse as the Department of Defense, banks, federal agencies, manufacturing companies, and health(More)
OBJECTIVE To determine the association between human milk (HM) intake and risk of necrotizing enterocolitis (NEC) or death among infants 401 to 1000 g birth weight. STUDY DESIGN Analysis of 1272 infants in the National Institute of Child Health and Human Development Neonatal Network Glutamine Trial was performed to determine if increasing HM intake was(More)
Standards have been instrumental in achieving the significant level of systems interoperability we rely on in almost every domain. Many organizations are betting on the ability of standards to provide unprecedented end-to-end systems interoperability with partner organizations. Our experience suggests that the expectation of what can be achieved with(More)
In commercial-off-the-shelf (COTS) multi-core systems, the execution times of tasks become hard to predict because of contention on shared resources in the memory hierarchy. In particular, a task running in one processor core can delay the execution of another task running in another processor core. This is due to the fact that tasks can access data in the(More)
AADL is a modeling language to design and analyze High-Integrity Distributed and Real-time systems. Embedded sub-languages published as AADL annexes extend an AADL model to enhance analysis. The behavior annex specifies the behavior of an AADL application model. Thus, an implantation of this annex allows to perform behavior analysis. In addition, as there(More)
Over the past decade, the complexity of new and acquired systems of systems has increased dramatically. Until now, research has mainly focused on the properties of systems of systems. Recently, paradigms such as service oriented  architecture (SOA) and Grid computing are being adopted to implement systems of systems. Additionally, techniques(More)
Traditional hard real-time scheduling algorithms require the use of the worst-case execution times to guarantee that deadlines will be met. Unfortunately, many algorithms with parameters derived from sensing the physical world suffer large variations in execution time, leading to pessimistic overall utilization, such as visual recognition tasks. In this(More)
