Experimental and numerical study on the mitigation of autogenous shrinkage of cementitious material

This study experimentally investigated the effects of surfactants and water-repelling agents on the hydration process, relative humidity, and mechanical properties of Portland cement pastes. Based on the measurement results, the degree of hydration, degree of saturation, capillary tension of autogenous shrinkage, and magnitude of autogenous...

Position-based dynamics simulator of vessel deformations for path planning in robotic endovascular catheterization

A major challenge during autonomous navigation in endovascular interventions is the complexity of operating in a deformable but constrained workspace with an instrument. Simulation of deformations for it can provide a cost-effective training platform for path planning. Aim of this study is to develop a realistic, auto-adaptive, and visually...

Prediction-Based Reachability Analysis for Collision Risk Assessment on Highways

Real-time safety systems are crucial components of intelligent vehicles. This paper introduces a prediction-based collision risk assessment approach on highways. Given a point mass vehicle dynamics system, a stochastic forward reachable set considering two-dimensional motion with vehicle state probability distributions is firstly established. We...

Virtual Operating Room Simulation Setup (VORSS) for Procedural Training in Minimally Invasive Surgery: a Pilot Study

Virtual reality (VR) training is widely used in several minimal invasive surgery (MIS) training curricula for procedural training. However, VR training in its current state lack immersive training environments, such as using head-mounted displays that is implemented in military or aviation training and even entertainment. The virtual...

Co-simulation of energy transition in residential sectors of Chinese lower-tier cities

China is undergoing large changes to tackle carbon dioxide emissions and air pollution. While the top-down governance allows for clear setting of emission reduction targets for industrial sectors and major cities, reducing emissions in residential sectors in smaller (the so-called low-tier) cities remain challenging and often unaddressed. This...

Dynamic traffic assignment model for inland waterway freight transport

Due to the rapid increase of global trade and deepening integration within the European Union (EU), freight transport across the EU has had relatively fast growth. However, constraints of transport infrastructure, interoperability and governance issues do slow down the developments of freight transport. There is a need for transport planning...
