Aiming at the uncertainty between evaluation samples and standards in of water environment carrying capacity, a five-element connection coefficient model for capacity based on set pair analysis theory is constructed, partial method subtractive potential are used. The development trend state was analyzed, used dynamic HJ City. results show that city 2015-2021 grades IV III, poor, but overall dev...

in this paper we introduce the concept of weakly prime ternary subsemimodules of a ternary semimodule over a ternary semiring and obtain some characterizations of weakly prime ternary subsemimodules. we prove that if $n$ is a weakly prime subtractive ternary subsemimodule of a ternary $r$-semimodule $m$, then either $n$ is a prime ternary subsemimodule or $(n : m)(n : m)n = 0$. if $n$ is a $q$-...

A neuro-fuzzy system based on a radial basis function network and using support vector learning is considered for non-linear modeling. In order to reduce the number of fuzzy rules, and improve the system interpretability, the proposed method proceeds in two phases. Firstly, the input-output data is clustered according to the subtractive clustering method. Secondly the parameters of the network,...

Amethodology for automatically identifying and clustering semantic features or topics in a heterogeneous text collection is presented. Textual data is encoded using a low rank nonnegative matrix factorization algorithm to retain natural data nonnegativity, thereby eliminating the need to use subtractive basis vector and encoding calculations present in other techniques such as principal compone...

The reaction of species in solutions flowing laminarly (without turbulent mixing) inside capillaries was used as the basis for a broadly applicable method of microfabrication. In this method, patterning occurs as a result of transport of reactive species to interfaces within the capillary by laminar flow. A wide range of chemistries can be used to generate structures with feature sizes of less ...

We consider varieties of pointed lattice-ordered algebras satisfying a restricted distributivity condition and admitting a very weak implication. Examples of these varieties are ubiquitous in algebraic logic: integral or distributive residuated lattices; their {·}-free subreducts; their expansions (hence, in particular, Boolean algebras with operators and modal algebras); and varieties arising ...

Economists and neuroscientists often explain game playing by assuming that humans try to predict the opponent's behavior on the basis of her past choices. We try to question this assumption in a Prisoner's Dilemma Game by using a methodology which we call the “subtractive behavioral method”. Our aim is to investigate which task features make participants attend to the opponent's behavior or, on...

A micromethod involving the use of fluorescent derivatives of 1-dimethylaminonaphthalene-5-sulphonyl chloride (Gray & Hartley, 1963) has been used in a parallel study of the structure of peptide C8Pla (as defined by Ambler, 1963) of the Pseudomonas cytochrome c-551. The basis of the method was a modification of the phenyl isothiocyanate procedure for the removal of the N-terminal residue (Edman...

In this paper, we propose a novel method, called local nonnegative matrix factorization (LNMF), for learning spatially localized, parts-based subspace representation of visual patterns. An objective function is defined to impose localization constraint, in addition to the non-negativity constraint in the standard NMF [1]. This gives a set of bases which not only allows a non-subtractive (part-b...
