Oblique impact responses of Hybrid III and a new headform with more biofidelic coefficient of friction and moments of inertia

Frontiers in Bioengineering and Biotechnology, 2022
New oblique impact methods for evaluating head injury mitigation effects of helmets are emerging, which mandate measuring both translational and rotational kinematics of the headform. These methods need headforms with biofidelic mass, moments of inertia (

Evaluation of a Curriculum-Based Elementary School BikeSafe Program. [PDF]

J Sch Health
ABSTRACT Background Children in urban areas face elevated risk for bicycle‐related injuries, yet few evidence‐based curricula address bicycle safety for elementary school physical education (P.E.) settings. Methods The BikeSafe Elementary School Curriculum (BESC) is an off‐bicycle, standards‐aligned program for grades 2–5. From August 2024 to May 2025,

What Do Large Language Models Know About Materials?

Advanced Engineering Materials, EarlyView.
If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...

Investigating helmet promotion for cyclists: results from a randomised study with observation of behaviour, using a semi-automatic video system.

PLoS ONE, 2012
IntroductionHalf of fatal injuries among bicyclists are head injuries. While helmet use is likely to provide protection, their use often remains rare.

Evaluating Energy Absorption Performance of Filled Lattice Structures

Advanced Engineering Materials, EarlyView.
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

WPAN and IoT Enabled Automation to Authenticate Ignition of Vehicle in Perspective of Smart Cities

Sensors, 2021
Currently, two-wheelers are the most popular mode of transportation, driven by the majority the people. Research by the World Health Organization (WHO) identifies that most two-wheeler deaths are caused due to not wearing a helmet.

Explaining the Origin of Negative Poisson's Ratio in Amorphous Networks With Machine Learning

Advanced Intelligent Discovery, EarlyView.
This review summarizes how machine learning (ML) breaks the “vicious cycle” in designing auxetic amorphous networks. By transitioning from traditional “black‐box” optimization to an interpretable “AI‐Physics” closed‐loop paradigm, ML is shown to not only discover highly optimized structures—such as all‐convex polygon networks—but also unveil hidden ...
