This paper reports the results of a study performed for the Oregon Department of Energy. The objectives of the study were to characterize the range of radioactive material shipments through the state and to determine the worst radiological hazards which might arise if these shipments were involved in transportation accidents. The direct and indirect radiological hazards were analyzed for worst ...

This paper describes methodologies that may be used to extend the intervals applied to the periodic leakage rate testing of certified type B transportation packagings that are loaded but not immediately shipped. In some cases, the packagings may be held in interim storage for more than 1 year, and the immediate goal is to extend the leakage rate testing interval from 1 up to as many as 5 years....

In recent years the interest in monitoring infrastructures has spread in many application domains, even because of the number of natural disasters and terrorist attacks. This important activity can be seen in the general context of critical infrastructure protection such as the freight train meant for hazardous materials transportation. The design of these systems must answer to several issues:...

hazards in different areas have different effects and consequences. nowadays considering industries vital conditions, it seems necessary to boost organizations confronting uncertainties and risks. one solution for reducing these risks, is increasing agility, stability and flexibility in production process. this study tries to increase organization capabilities in supply chain hazards handing, u...

transportation is by people and for them. it is a process of providing mobility and accessibility for people both as passengers and as consumers of the goods. therefore it is true when today there is an emphasis on the considering transportation the most influential development in every society. regional development cannot properly be happened without enough transportation infrastructure and qu...

− In this paper a cost-effective method for measuring transportation velocity and the velocity profile of a material flow of powdery solids inside a pipe is presented. For the measurement, artificial perturbations are brought into the mass flow and the effects of these perturbations are acquired and correlated at measurement sections. The velocity profile is calculated with the knowledge of the...

The theoretical advantages that Silicon Carbide (SiC) material offers are being realized by using prototype or experimental devices in many different applications ranging from medium voltage to high voltage. The main advantages of using SiC based devices are reduced thermal management requirements and smaller passive components which result in higher power density. An overview of the SiC resear...

Overhead cranes are widely used in industrial applications for material displacing. Many linear or nonlinear control schemes have been proposed for overhead cranes and implemented on electronic systems, but energy efficiency of transportation has seldom been considered in motion planning. This paper aims at finding an optimal solution of motion planning in terms of energy efficiency for overhea...

The aim of this paper is to present a decentralized control architecture for an autonomous transportation system in the manufacturing facility of the future. Each component in the factory (machine, robot, operator...) is represented as an individual agent on the cloud and makes autonomous decisions based on the information exchanged with other agents. Production machines control their own mater...
