Unsharp Degrees of Freedom and the Generating of Symmetries [PDF]

open access: yes, 1999
In quantum theory, real degrees of freedom are usually described by operators which are self-adjoint. There are, however, exceptions to the rule. This is because, in infinite dimensional Hilbert spaces, an operator is not necessarily self-adjoint even if

Interval type-2 fuzzy logic system for diagnosis coronary artery disease

open access: yesCommunications in Science and Technology, 2016
Coronary artery disease (CAD) is a disease that has been the deadliest disease in Indonesia. The ratio of cardiologists over potential patients is not appropriate either.

A Deep Spatio-Temporal Fuzzy Neural Network for Passenger Demand Prediction [PDF]

open access: yes, 2019
In spite of its importance, passenger demand prediction is a highly challenging problem, because the demand is simultaneously influenced by the complex interactions among many spatial and temporal factors and other external factors such as weather.

Uncertainty Analysis of the Adequacy Assessment Model of a Distributed Generation System [PDF]

open access: yes, 2012
Due to the inherent aleatory uncertainties in renewable generators, the reliability/adequacy assessments of distributed generation (DG) systems have been particularly focused on the probabilistic modeling of random behaviors, given sufficient informative

Centroid of an Interval Type-2 Fuzzy Set: Continuous vs. Discrete

open access: yesIngeniería, 2011
Karnik-Mendel algorithm involves execution of two independent procedures for computing the centroid of an interval type-2 fuzzy set: the first one for computing the left endpoint of the interval centroid (which is denoted by cl), and the second one for ...
