first principle calculations were performed using density functional theory within the local spin density approximation (lsda) to understand the electronic properties of au(100)+tbt system and compare the results with au(100) and bulk au properties. band structure, the total dos and charge density for these materials are calculated. we found that the homo for au(100)+tbt becomes broader than au...

this paper describes the development of a fuzzy decision support system (fdss) for the assessment of risk in e-commerce (ec) development. a web-based prototype fdss is suggested to assist ec project managers in identifying potential ec risk factors and the corresponding project risks. a risk analysis model for ec development using a fuzzy set approach is proposed and incorporated into the fdss....

presence of risks and uncertainties inherent in project development and implementation playssignificant role in poor project performance. thus, there is a considerable need to have an effective riskanalysis approach in order to assess the impact of different risks on the project objectives. a powerful riskanalysis approach may consider dynamic nature of risks throughout the life cycle of the pr...

Abstract. Oceanic dissolved inorganic carbon (TC) is the largest pool of that substantially interacts with atmosphere on human timescales. TC increasing through uptake anthropogenic dioxide (CO2), and seawater pH decreasing as a consequence. Both exchange CO2 between ocean response are governed by set parameters interact chemical equilibria, collectively known marine carbonate system. To invest...
