Despite the many touted benefits of nanotechnology, considerable uncertainty exists regarding full-scale production costs, occupational health risks, and future regulatory standards. Monte Carlo models were developed to investigate the implications of these uncertainties on high pressure carbon monoxide (HiPco) processes, a common single wall carbon nanotube (SWNT) production method. The health...

Late effects from the high charge and energy (HZE) ions present in the galactic cosmic rays (GCR) including cancer and the poorly understood risks to the central nervous system constitute the major risks for exploration missions. Methods used to project risk in low Earth orbit (LEO) are viewed as highly uncertain for projecting risks on exploration missions because of the limited radiobiology d...

the issue of successful project management and control is of vital importance in today’s world. although the time and cost of any project is determined in advance, paying less attention to an appropriate control and revision will result in a small chance of reaching those goals. the earned value management method that shows deviation of projects schedules and costs is of the good method for thi...

As a matter of course, power market uncertainties escalation is by product of power industry restructure on one hand and the unrivalled penetration of renewable energies on the other. Generally, the decision making process in such an uncertain environment faces with different risks. In addition, the performance of real power markets is very close to oligopoly markets, in which, some market play...

The design of distribution networks is prone to risks due to the uncertainties associated with factors that change over time. In this paper we present a new method to identify those factors that the structure of a distribution network is most sensitive to. The new method combines simulation and the Taguchi technique to allow a wide range of factor uncertainties to be evaluated without excessive...

Resilient operation of microgrid is an important concept in modern power system. Its goal is to anticipate and limit the risks, and provide appropriate and continuous services under changing conditions. There are many factors that cause the operation mode of micogrid changes between island and grid-connected modes. On the other hand, nowadays, electric vehicles (EVs) are desirable energy storag...

Long-term effects of genetically modified (GM) crops on health, biodiversity and the environment: prioritisation of potential risks and delimitation of uncertainties

This paper investigates the sorts of risks and uncertainties inherent in implementing an e-learning information systems project in Estonia. The study uses a variation of the Delphi study in eliciting the risk factors or items from experienced top management professionals within the organisation. The main objective of the study is to identify the uncertainties or risks in the implementation of t...
