Dempster Shafer theory of evidence (DS theory) and possibility theory are two main formalisms in modelling and reasoning with uncertain information. These two theories are inter-related as already observed and discussed in many papers (e.g. [DP82,DP88b]). One aspect that is common to the two theories is how to quantitatively measure the degree of conflict (or inconsistency) between pieces of un...

Uncertainty importance measures typically reflect the degree to which uncertainty about risk and reliability parameters at the component level influences uncertainty about parameters at the system level. The definition of these measures is typically founded on a Bayesian perspective where subjective probabilities are used to express epistemic uncertainty; hence, they do not reflect the effect o...

Hydroxamic acids are salt free, organic compounds with affinities for cations such as Fe, Np and Pu and have been identified as suitable reagents for the control of Pu and Np in advanced nuclear fuel reprocessing. The results of a UV-visible-near IR spectrophotometric study of the 1:1 and 2:1 complexes formed between formoand acetohydroxamic acids (FHA, AHA) and Np(IV) ions are interpreted usin...

The study of new energy carriers for sustainable energy conversion processes is a hot research area. Among the potential energy carriers one finds biogas, containing a large fraction of methane, which attracts high interests worldwide. However, to be more useful, e.g., concerning storage and transportation, conversion of gaseous methane fuel into liquid fuel like methanol is desired. The conven...

Paper and garden waste is one of the types that can be found in big cities Indonesia, which Depok City. Garbage collectors recycle not all paper into new products. In addition, also garbage, wastes produced every day from gardening activities. This study aimed to analyze potential for reducing use used as RDF analyzes quality based on parameters water content, ash density, calorific value resul...

Uranium is an important carbon-free fuel source and environmental contaminant that accumulates in the tetravalent state, U(IV), in anoxic sediments, such as ore deposits, marine basins, and contaminated aquifers. However, little is known about the speciation of U(IV) in low-temperature geochemical environments, inhibiting the development of a conceptual model of U behavior. Until recently, U(IV...

based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. however, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. to resolve this problem, hybridization of the fuel cell and energy storage device...
