Risk management in fast-track projects
This thesis is about risk management in fast-track construction projects. The aim of the study is to identify the risks in the UAE construction industry, understand how they are dealt with, and propose more effective frameworks for risk management in fast-track construction. A mixed method approach …

Development of track-walking DNA nanomotors
Artificial nanowalkers are inspired by bimolecular counterparts from living cells. More than a dozen of nanowalkers have been fabricated and demonstrated by various rectification mechanisms and driving methods, including ratchet and burn-the-bridge for the former and fuels, enzymes, light for the …

Vertical dynamics of railway vehicle-track system
… finite element (FE) model of railway vehicle-track system is developed to study the dynamic interaction between the vehicle and track. The vehicle is represented by a lumped parameter system. The track is modeled as a Timoshenko beam on discrete pad-tie-ballast supports. The tie is considered …
