Teleoperated Control of Hydraulic Equipment for Hazardous Material Handling
Traditionally, teleoperation has been an expensive and lengthy process. This thesis shows that by incorporating off-the-shelf technology into a modular design, teleoperation can be developed rapidly and inexpensively. Within six months and a hardware cost of $20k, a group of Virginia Tech students …

Path Prediction and Path Diversion Identifying Methodologies for Hazardous Materials Transported by Malicious Entities
Safe and secure transportation of hazardous materials (hazmat) is a challenging issue in terms of optimizing risk to society and simultaneously making the shipment delivery economical. The most important safety concern of hazardous material transportation is accidents causing multiple causalities. …

A simulation study for hazardous materials transportation risk assessment
All the areas in Canada are subjected to risk by hazardous-materials shipments. Some of these shipments take place locally or regionally, but a large number of them involve inter-provincial movements across significant distances, and this introduces further complications. According to a 1997 report …
