Pedestrian Interaction Modelling: Leveraging Trajectory Prediction for Belief Representation

Autonomy in traffic (e.g., autonomous vehicles) could potentially benefit mobility, safety, accessibility and sustainability. However, the realisation of these advancements is highly dependent on how effective these autonomous vehicles interact with vulnerable road users such as pedestrians. Before we can understand how pedestrians will interact...

Parametric investigation of railway fastenings into the formation and mitigation of short pitch corrugation

Short pitch corrugation has been a problem for railways worldwide over one century. In this paper, a parametric investigation of fastenings is conducted to understand the corrugation formation mechanism and gain insights into corrugation mitigation. A three-dimensional finite element vehicle–track dynamic interaction model is employed, which...

Short pitch corrugation mitigation by rail constraint design

Short pitch corrugation is a quasi-periodic rail defect that induces a high level of noise and accelerates track degradation. This paper proposes a methodology to mitigate short pitch corrugation by rail constraint design, including four steps. In Step 1, corrugation is numerically reproduced by employing a three-dimensional (3D) finite...

Selecting Robots to Take Over Tasks in Hospitality Settings: Joining Two Research Fields

Robotic assistance for work processes in the hospitality industry is receiving increased attention both in the hospitality industry and in academic research. Unfortunately, academic literature about hospitality robotics is currently disjointed, making it hard for hospitality professionals to decide which processes to target, and which...

Characterization and mitigation of wheel-rail impact at a singular rail defect

Wheel-rail impact, which arises from structural discontinuities and short-wave defects, becomes more serious with higher train speeds and larger axle loads. The large impact load can accelerate the deterioration of vehicle-track components and induce a high level of impact noise. This paper aims to better understand the characteristics of...

An interactive design tool for urban planning using the size of the living space as unit of measurement

In urban planning, a common unit of measurement for population density is the number of households per hectare. However, the actual size of the households is seldom considered, neither in 2D nor in 3D. This paper proposes a method to calculate the average size of the household in existing urban areas from available open data and to use it as a...

An interactive model among potential human risk factors: 331 cases of coal mine roof accidents in China

In order to explore optimal strategies for managing potential human risk factors, this paper developed an interactive model among potential human risk factors based on the development processes of accidents. This model was divided into four stages, i.e., risk latency stage, risk accumulation stage, risk explosion stage and risk residue stage....

SimDelta global: Towards a standardised interactive model for water infrastructure development

The research project ‘SimDelta’ builds on novel internet technology to support the development of the Rhine-Meuse delta water infrastructure. It has three goals: education, organisation of research and design studies, and stakeholder polling. A current question is how the SimDelta technology could be made transferable to systems outside Europe,...

WoodWeaver: Fabricating curved objects without moulds or glue

design a single free-form curved surface and to fabricate it based on the bending deformation characteristics of the material. The system also indicates an invalid shape; that is, one that will break upon bending deformation. The user can then design a valid shape with this information. We also develop an optimal Dukta pattern that is the...
