Mixed-criticality networks for adaptive systems

29th Digital Avionics Systems Conference, 2010
A crucial aspect of mission-critical vehicles is their reaction to environmental or system-internal changes. Ideally, the new situation is autonomously assessed and the vehicle's behavior is adapted accordingly. Modern mission-critical vehicles realize a network-centric design approach, for one reason because it follows the inherent requirements of ...

Four-wave mixing critical slowing down

Optics Communications, 1991
Abstract Four-wave mixing with cross-polarised pump beams is known to produce infinite phase conjugate reflectivities at a coupling strength of ΓL =4 in the undepleted pumps approximation. Theoretical results presented here show that within this approximation an effective grating time constant also tends to infinity at this coupling strength i.e ...

Implementing Mixed Criticality Systems in Ada

2011
Many safety-critical embedded systems are subject to certification requirements. However, only a subset of the functionality of the system may be safety-critical and hence subject to certification; the rest of the functionality is non safety-critical and does not need to be certified, or is certified to a lower level.

Smart Certification of Mixed Criticality Systems

2005
High integrity applications, such as those performing safety or security critical functions, are usually built to conform to standards such RTCA DO-178B [1] or UK Def Stan 00-55 [2]. Typically such standards define ascending levels of criticality each of which requires a different and increasingly onerous level of verification.

Specifying Fault-Tolerant Mixed-Criticality Scheduling

© The Author(s), under exclusive license to Springer Nature Switzerland AG 2024. This paper extends the ideas behind rely-guarantee conditions to cope with the specification of real-time schedulers that support Fixed Priority (FP) scheduling. The sporadic task model is considered in which tasks with defined minimum periods and worst-case execution ...
