Previous studies identified comorbidities as predictors of older driver performance and driving pattern, while the direct impact of comorbidities on road crash risk in elderly drivers is still unknown. The present study is a cross-sectional aimed at investigating the association between levels of comorbidity and crash involvement in adult and elderly drivers. 327 drivers were stratified accordi...

BACKGROUND Low and middle-income countries carry over ninety per cent of the burden of injury related mortality and disability. Motorcycles are gradually becoming a major mode of transportation in Cameroon and other African countries in the absence of an organized public transport. Consequently, the contribution of motorcycle crash to injury-related deaths seems to be on the rise. Currently, da...

Most states currently use ranking procedures to identify intersections with safety concerns. One objective of a state intersection ranking procedure is to provide a reliable start to the prioritization of safety improvements. For efficiency purposes, it is crucial to have a ranking system that identifies intersections with the most severe safety concerns. Otherwise, potentially hazardous inters...

Although speed is considered to be one of the main crash contributory factors, research findings are inconsistent. Independent of the robustness of their statistical approaches, crash frequency models typically employ crash data that are aggregated using spatial criteria (e.g., crash counts by link termed as a link-based approach). In this approach, the variability in crashes between links is e...

The publication of the pivotal state machine replication protocol PBFT laid foundation for a body BFT protocols. We introduce probabilistic model evaluating protocols in presence dynamic link and crash failures. is derived from communication pattern, facilitating an adaptation to other replicas captured used derive success probability execution. To this end, we examine influence failure rates a...

• The 2020 U.S. stock market crash stems from its own systemic instability. COVID-19 merely served as the spark of crash. Bubble for stocks with different cap levels have distinct temporal profiles. Stock sectors middle and small suffer greater losses. We employed log-periodic power law singularity (LPPLS) methodology to systematically investigate in equities total capitalizations through four ...

Failure detectors of the class denoted Pt eventually suspect all crashed processes in a permanent way (completeness) and ensure that, at any time, no more than n− t−1 alive processes are falsely suspected (accuracy), n being the total number of processes. This paper first shows that a simple combination of such a failure detector with a two-step communication pattern can provide the processes w...

This paper investigates the design of fault-tolerant TDMA-based data aggregation scheduling (DAS) protocols for wireless sensor networks (WSNs). DAS is a fundamental pattern of communication in wireless sensor networks where sensor nodes aggregate and relay data to a sink node. However, any such DAS protocol needs to be cognisant of the fact that crash failures can occur. We make the following ...

This paper presents a new method for designing vehicle structures for crashworthiness using surrogate models and a genetic algorithm. Inspired by the classifier ensemble approaches in pattern recognition, the method estimates the crash performance of a candidate design based on an ensemble of surrogate models constructed from the different sets of samples of finite element analyses. Multiple su...
