A Dual Learning Model for Vehicle Trajectory Prediction

open access: yesIEEE Access, 2020
Automated vehicles and advanced driver-assistance systems require an accurate prediction of future traffic scene states. The tendency in recent years has been to use deep learning approaches for accurate trajectory prediction but these approaches suffer ...

Accident investigation [PDF]

open access: yes, 1979
Aircraft accident investigations are discussed with emphasis on those accidents that involved weather as a contributing factor. The organization of the accident investigation board for air carrier accidents is described along with the hearings, and ...

Jet Substructure by Accident [PDF]

open access: yes, 2013
We propose a new search strategy for high-multiplicity hadronic final states. When new particles are produced at threshold, the distribution of their decay products is approximately isotropic.

On the Deformation Behavior of Metastable CrMnNi Steels Processed by Directed Energy Deposition in Different Temperature Regimes

open access: yesAdvanced Engineering Materials, EarlyView.
In the present study, metastable CrMnNi steels with varying chemical compositions and a concomitantly altered stacking fault energy are processed via directed energy deposition and afterwards tested via tensile tests at different temperatures. The present study shows the influence of the manufacturing process on the elemental deformation mechanisms for

Assessing self-reported risky behavior among two-wheeled vehicle users: an exploratory analysis comparing e-bikers to other riders

open access: yesEuropean Transport Research Review, 2021
The current deployment of e-bikes in large cities all over the world raises new road safety problems. The shared features of e-bikes and other types of two-wheelers, notably in terms of size and maneuverability, can lead to common road safety issues and ...

Development of accident prediction model by using artificial neural network (ANN) [PDF]

open access: yes, 2011
Statistical or crash prediction model have frequently been used in highway safety studies. They can be used in identify major contributing factors or establish relationship between crashes and explanatory accident variables.

Predicting the cost of the consequences of a large nuclear accident in the UK [PDF]

open access: yes, 2017
Nuclear accidents have the potential to lead to significant off-site effects that require actions to minimise the radiological impacts on people. Such countermeasures may include sheltering, evacuation, restrictions on the sale of locally-grown food, and

Sonication‐Assisted Palladium Nanogaps in a Capacitive Structure: A Tunable and Reliable Solution for Sensitive Hydrogen Monitoring

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a capacitive hydrogen sensor with a simple structure and process. Sonication‐induced Pd nanogaps modulate the effective electrode area in response to hydrogen concentration, resulting in capacitance changes within a range predefined by physical parameters.

No inflammatory effects after acute inhalation of barium sulfate particles in human volunteers

open access: yesBMC Pulmonary Medicine, 2022
Background Most threshold limit values are based on animal experiments. Often, the question remains whether these data reflect the situation in humans. As part of a series of investigations in our exposure lab, this study investigates whether the results
