Quantifying Safety of Laser-Based Navigation

IEEE Transactions on Aerospace and Electronic Systems, 2019
In this paper, a new safety risk evaluation method is developed, simulated, and tested for laser-based navigation algorithms using feature extraction (FE) and data association (DA). First, at FE, we establish a probabilistic measure of separation between features to quantify the sensor's ability to distinguish landmarks.

Non‐Additive Criteria Assessment in Sustainability Evaluation of High Entropy Alloys: A Toxicity‐Weighted Framework

Advanced Engineering Materials, EarlyView.
Sustainability assessment requires methodologies that appropriately distinguish between additive and non‐additive material properties. A toxicity‐weighted scoring system is developed and applied that accounts for the disproportionate influence of highly toxic constituents through nonlinear weighting functions, providing more realistic estimates than ...

Navigating Paramedics' Safety

International Journal of Paramedicine
Background: Ambulance drivers are more likely to be involved in fatal or injury collisions compared to other professional drivers. Study Objective: This study is a retrospective study aimed to describe factors involved in paramedics’ collisions. Method: Spanning over 10 years of data (2010-2019) from a paramedic agency covering Montreal (Qc, Canada),

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).
