Mixed-Criticality with Integer Multiple WCETs and Dropping Relations: New Scheduling Challenges

Scheduling Mixed-Criticality (MC) workload is a challenging problem in real-time computing. Earliest Deadline First Virtual Deadline (EDF-VD) is one of the most famous scheduling algorithm with optimal speedup bound properties. However, when EDF-VD is used to schedule task sets using a model with additional or relaxed constraints, its scheduling properties change. Inspired by an application of MC to the scheduling of fault tolerant tasks, in this article, we propose two models for multiple criticality levels: the first is a specialization of the MC model, and the second is a generalization of it. We then show, via formal proofs and numerical simulations, that the former considerably improves the speedup bound of EDF-VD. Finally, we provide the proofs related to the optimality of the two models, identifying the need of new scheduling algorithms

A Case of Gout from Imperial Rome (1st-2nd Century AD)

The study of pathological alterations in ancient skeletal remains may contribute to the reconstruction of the history of diseases and health conditions of ancient populations. Therefore, in recent research palaeopathology provides an important point of view in bioarchaeology and medicine. This work describes the bone alterations observed in the skeleton of an adult woman found during archaeological excavations in the greatest necropolis of the Imperial Age in Rome. The skeletal remains showed some pathological anomalies and the most evident alterations consisted of multiple osteolytic lesions involving mainly the small bones of the feet, which presented round cavitations and scarce signs of bone repair. Differential diagnosis suggests that this individual was affected by gout, probably associated with hypothyroidism that determined her short stature
