|||||||||||||||||||||||||||||||Abstract In this paper, the researcher proposes a modi ed new method to rank L-R fuzzy numbers. The modi ed method uses a defuzzi cation of parametrically represented fuzzy numbers that have been studied in [20]. This parameterized defuzzi cation can be used as a crisp approximation with respect to a fuzzy quantity. In this article, the researcher uses this defuzz...

Cleaning validation (CV) is a Good Manufacturing Practices (GMP) requirement in manufacturing of drug substances and drug products. Liquid Chromatography with UV detection is a common choice for cleaning verifi cation studies for most drugs at sensitivity levels of approximately 20–50 ng/mL. For highly potent drugs, CV methods to reach sensitivity levels of low ng/mL can be implemented using UV...

The interplay between identi cation of a predictor and the convexity of an associated optimization-based control problem is studied. The reason for the appearance of nonconvexity is investigated and a method to favour convexity of the optimization-based control problem in the identi cation problem is suggested. Further, a parametrization which makes the identi cation problem tractable is propos...

In our previous work, an effective preconditioning scheme that is based upon constructing least-squares approximation cardinal basis functions (ACBFs) from linear combinations of the RBF-PDE matrix elements has shown very attractive numerical results. The preconditioner costs O(N2) flops to set up and O(N) storage. The preconditioning technique is sufficiently general that it can be applied to ...

This paper describes two new bunsetsu identi cation methods using supervised learning. Since Japanese syntactic analysis is usually done after bunsetsu identi cation, bunsetsu identi cation is important for analyzing Japanese sentences. In experiments comparing the four previously available machinelearning methods (decision tree, maximum-entropy method, example-based approach and decision list)...

This article introduces a new method of a decision tree construction. Such decision tree is constructed with the usage of additional cuts that are used for a veri cation of cuts in tree nodes during the classi cation of objects. The presented approach allows the use of additional knowledge contained in the attributes which could be eliminated using greedy methods. The paper includes the results...

in concentration of hydrogen peroxide, first, the solution should be quite pure, and then, it concentrate with methods such as vacuum distillation and cooling crystallization, because impurities in the hydrogen peroxide solution in high concentrations are causing decomposition of this substance; that is very dangerous. the purpose of this article is separation of chromium and magnesium cations ...

in this study, a multi-objective genetic algorithm (moga) is utilized to extract interpretable and compact fuzzy rule bases for modeling nonlinear multi-input multi-output (mimo) systems. in the process of non- linear system identi cation, structure selection, parameter estimation, model performance and model validation are important objectives. furthermore, se- curing low-level and high-level ...
