Implementing Mixed-criticality Systems Upon a Preemptive Varying-speed Processor [PDF]

Leibniz Transactions on Embedded Systems, 2014
A mixed criticality (MC) workload consists of components of varying degrees of importance (or "criticalities"); the more critical components typically need to have their correctness validated to greater levels of assurance than the less critical ones ...

FlexPRET: A processor platform for mixed-criticality systems [PDF]

2014 IEEE 19th Real-Time and Embedded Technology and Applications Symposium (RTAS), 2014
Mixed-criticality systems, in which multiple tasks of varying criticality execute on a single hardware platform, are an emerging research area in real-time embedded systems. High-criticality tasks require spatial and temporal isolation guarantees for independent verification, and the task set should efficiently utilize hardware resources.

Mixed-Criticality Scheduling with Dynamic Redistribution of Shared Cache [PDF]

, 2017
The design of mixed-criticality systems often involves painful tradeoffs between safety guarantees and performance. However, the use of more detailed architectural models in the design and analysis of scheduling arrangements for mixed-criticality systems

Mixed-Criticality Scheduling of Sporadic Task Systems [PDF]

, 2011
We consider the scheduling of mixed-criticality task systems, that is, systems where each task to be scheduled has multiple levels of worst-case execution time estimates. We design a scheduling algorithm, EDF-VD, whose effectiveness we analyze using the processor speedup metric: we show that any 2-level task system that is schedulable on a unit-speed ...

Learning-Oriented QoS- and Drop-Aware Task Scheduling for Mixed-Criticality Systems

Computers, 2022
In Mixed-Criticality (MC) systems, multiple functions with different levels of criticality are integrated into a common platform in order to meet the intended space, cost, and timing requirements in all criticality levels.

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Broadband criticality of human brain network synchronization [PDF]

, 2009
Self-organized criticality is an attractive model for human brain dynamics, but there has been little direct evidence for its existence in large-scale systems measured by neuroimaging. In general, critical systems are associated with fractal or power law

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.
