Abstract The concept of fuzzy set has been extended by neutrosophic sets to represent whose elements have different degrees membership characterized a truth-membership function, an indeterminacy-membership function and falsity-membership function. It is usually assumed that these functions are linear, hence excluding the possibility non-linearity in many decision-making situations. From alterna...

Power systems face adequacy risks because of the high integration renewable energy. It is urgent to develop efficient methods for power system operational reliability assessment. Conventional assessment cannot achieve real-time risk computational complexity and long calculation time. The mainly caused by a large number optimal flow (OPF) calculations. To reduce complexity, this paper transfers ...

OBJECTIVES Occupational exposure assessment is a major task in industrial hygiene studies. Although statistical analyses for magnitudes and variations of exposures to various types of working populations based on existing data sets are extensive, relatively few discussions on study designs appear in the literature, especially for sample size determination and number of repeated measurements. ...

Relative importance of regressor variables is an old topic that still awaits a satisfactory solution. When interest is in attributing importance in linear regression, averaging over orderings methods for decomposing R2 are among the state-of-theart methods, although the mechanism behind their behavior is not (yet) completely understood. Random forests—a machinelearning tool for classification a...

A relatively simple shake-flask system for determining CO2 evolution was developed to assess the ultimate biodegradability by soil and sewage micro-organisms of chemicals which enter the environment. Linear alkylbenzene sulfonates (LAS) were used as model compounds to evaluate the method and were found to undergo substantial biodegradation in this dilute system. At the 30 mg/liter test concentr...
