Operators on Single Valued Trapezoidal Neutrosophic Numbers and SVTN-Group Decision Making [PDF]
Neutrosophic Sets and Systems, 2018 In this paper, we first introduce single valued trapezoidal neutrosophic (SVTN) numbers with their properties. We then define some operations and distances of the SVTN-numbers.

Solving the difference initial-boundary value problems by the operator exponential method [PDF]
, 2000 We suggest a modification of the operator exponential method for the numerical solving the difference linear initial boundary value problems. The scheme is based on the representation of the difference operator for given boundary conditions as the ...

Tracking Contaminant Transport Backwards with an Operator-Splitting Method
Mathematics, 2023 Recovering the past movement of a contaminant plume from measurements of its current values is a challenging problem in hydrology. Moreover, modeling the movement of a contaminant plume backwards is an ill-posed problem due to the unstable and non-unique

A Data-Driven Approximation of the Koopman Operator: Extending Dynamic Mode Decomposition [PDF]
, 2014 The Koopman operator is a linear but infinite dimensional operator that governs the evolution of scalar observables defined on the state space of an autonomous dynamical system, and is a powerful tool for the analysis and decomposition of nonlinear ...

Generalized dilatation operator method for non-relativistic holography
Physics Letters B, 2014 We present a general algorithm for constructing the holographic dictionary for Lifshitz and hyperscaling violating Lifshitz backgrounds for any value of the dynamical exponent z and any value of the hyperscaling violation parameter θ compatible with the ...

SPEECH/PAUSE SEGMENTATION METHOD BASED ON TEAGER ENERGY OPERATOR
Модели, системы, сети в экономике, технике, природе и обществе, 2022 Background. Speech segmentation into voiced, unvoiced sections and pauses is the key task for the majority of speech applications. This is especially important in systems for assessing human psycho-emotional state by speech, since duration of voiced ...

Noncommutative optimal control and quantum networks [PDF]
, 2006 Optimal control is formulated based on a noncommutative calculus of operator derivatives. The use of optimal control methods in the design of quantum systems relies on the differentiation of an operator-valued function with respect to the relevant ...

International Journal of Applied Mathematics and Computer Science, 2015 A new very high-order finite volume method to solve problems with harmonic and biharmonic operators for onedimensional geometries is proposed. The main ingredient is polynomial reconstruction based on local interpolations of mean values providing ...
