Priority rules are one of the most promising approaches to aircraft conflict resolution. This paper deals with the problem of priority assignment in autonomous Air Traffic Management with imperfect trajectory prediction. A robust solution is presented that relies on onboard traffic pattern classification using a data base common to all aircraft. The method allows reaching a common consensus in ...

We study the problem of priority inversion in distributed real-time and embedded systems and propose a solution based on a distributed version of the priority inheritance protocol (PIP). Previous approaches to priority inversions in distributed systems use variations of the priority ceiling protocol (PCP), originally designed for centralized systems as a modification of PIP that also prevents d...

It is over 40 years since the first seminal work on priority assignment for real-time systems using fixed priority scheduling. Since then, huge progress has been made in the field of real-time scheduling with more complex models and schedulability analysis techniques developed to better represent and analyse real systems. This tutorial style review provides an in-depth assessment of priority as...

Over 10 years ago, a National Research Council committee led by Jim Pellegrino and Robert Glaser generated the fundamental text on educational assessment titled, Knowing What Students Know: The Science and Design of Educational Assessment (NRC, 2001). In this document, the authors emphasize that assessment is a process of reasoning from evidence, ‘‘a process by which educators use students’ res...

This study describes the analysis of estragole in dry fennel preparations and in infusions prepared from them and an associated safety assessment. A wide range of estragole levels of 0.15-13.3mg/g dry fennel preparation was found. The estragole content in infusions was considerably lower ranging between 0.4 and 133.4μg/25mL infusion prepared from 1g dry material. Infusions prepared from whole f...

This paper focuses on the risks of environmental carcinogenic and/or genotoxic contaminants in food. It describes, for each contaminant studied, the carcinogenicity and genotoxicity, the toxicological reference values, the exposure and the risk characterisation. The compounds studied were classified into 3 categories based on a risk assessment. Effects others than carcinogenicity and/or genotox...

BACKGROUND The emergency medical services program at the College of Applied Medical Sciences, King Saud bin Abdulaziz University for Health Sciences, Riyadh, Kingdom of Saudi Arabia, was adapted from the integrated problem-based learning curriculum of Flinders University, Adelaide, South Australia. PURPOSE The purpose of this article is to discuss the major adaptations required for adoption o...

An independent panel of expert scientists and risk assessors met in Ottawa, Ontario to review a hazard identification and dose-response assessment on carbon disulfide. Health Canada developed the assessment on carbon disulfide as part of the Priority Substances Program under the Canadian Environmental Protection Act. This meeting was conducted by Toxicology Excellence for Risk Assessment (TERA)...
