Fault-Tolerance by Graceful Degradation for Car Platoons [PDF]

open access: yes, 2019
The key advantage of autonomous car platoons are their short inter-vehicle distances that increase traffic flow and reduce fuel consumption. However, this is challenging for operational and functional safety.

Anti‐Slip Material‐Based Strategies and Approaches

open access: yesAdvanced Materials Technologies, EarlyView.
This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

Integrating Dynamics and Wear Modelling to Predict Railway Wheel Profile Evolution [PDF]

open access: yes, 2003
The aim of the work described was to predict wheel profile evolution by integrating multi-body dynamics simulations of a wheelset with a wear model. The wear modelling approach is based on a wear index commonly used in rail wear predictions.

Behavioural compensation by drivers of a simulator when using a vision enhancement system [PDF]

open access: yes, 2000
Technological progress is suggesting dramatic changes to the tasks of the driver, with the general aim of making driving environment safer. Before any of these technologies are implemented, empirical research is required to establish if these devices do,

Terahertz Chiral Metamaterials Enabling Broadband Polarization Conversion Using Polarization Guiding Effect

open access: yesAdvanced Materials Technologies, EarlyView.
A broadband terahertz polarization rotator consisting of twistingly stacked silicon–air metagratings is designed based on the polarization guiding effect and experimentally shown to achieve 90° linear polarization rotation for both TE and TM incidences.

Lifestyle behaviour change for preventing the progression of chronic kidney disease: a systematic review

open access: yesBMJ Open, 2019
Objectives Modifying lifestyle can prevent the progression of chronic kidney disease (CKD) but the specific elements which lead to favourable behaviour change are not well understood.

New slip control system considering actuator dynamics [PDF]

open access: yes, 2015
A new control strategy for wheel slip control, considering the complete dynamics of the electro-hydraulic brake (EHB) system, is developed and experimentally validated in Cranfield University's HiL system.

Development of Heat Engines Powered by Twisted and Coiled Polymer Fiber Actuators

open access: yesAdvanced Materials Technologies, EarlyView.
Continuously rotating engines driven by thermally responsive actuating materials can turn waste heat into useful energy. For the first time heat engines operated by twisted and coiled polymer fiber actuators are demonstrated with engine design guided by two simple analytical models.

Bridging the gap between human behaviour and animal welfare: A study on human behaviour change and body condition scoring of suckler cows

open access: yesAnimal Welfare
There are several examples of best animal husbandry practices that are not adopted, leading to animal welfare compromises. Bridging this gap between advice and human behaviour is crucial in helping drive improvements in animal welfare.
