An alternative algorithm for a sliding window ULV decomposition
(Springer Wien, 2006)The ULV decomposition (ULVD) is an important member of a class of rank-revealing two-sided orthogonal decompositions used to approximate the singular value decomposition (SVD). The ULVD can be modified much faster than the ... -
Analysis of Thermal Environmental Effects on Precast, Prestressed Concrete Bridge Girders: Temperature Differentials and Thermal Deformations
(Multi-Science Publ Co Ltd, 2012)AASHTO specifications provide vertical thermal gradients for the thermal design of precast, prestressed concrete bridge girders. However, the thermal behavior of the girders pertains to not only vertical thermal movement ... -
An application of Ritt-Wu's zero decomposition algorithm to the pseudo null Bertrand type curves in Minkowski 3-space
(Springer Heidelberg, 2011)The Bertrand curves were first studied using a computer by Wu (1987). The same problem was studied using an improved version of Ritt-Wu's decomposition algorithm by Chou and Gao (1993). This paper investigates the same ... -
Applications of q-calculus in operator theory
(Springer New York, 2013)The approximation of functions by linear positive operators is an important research topic in general mathematics and it also provides powerful tools to application areas such as computer-aided geometric design, numerical ... -
Approximation by (p, q)-Baskakov-Durrmeyer-Stancu Operators
(Springer Basel Ag, 2018)The present paper deals with the Stancu-type generalization of (p, q)-Baskakov-Durrmeyer operators. We investigate local approximation, weighted approximation properties of new operators and present the rate of convergence ... -

(Springer, 2016)The main goal of this paper is to introduce Durrmeyer modifications for the generalized Szasz-Mirakyan operators defined in (Aral et al., in Results Math 65:441-452, 2014). The construction of the new operators is based ... -
Approximation by q Baskakov Beta operators
(Springer Heidelberg, 2011)In the present paper we introduce the q analogue of the Baskakov Beta operators. We establish some direct results in the polynomial weighted space of continuous functions defined on the interval [0, a). Then we obtain ... -
Approximation of functions of two variables by certain linear positive operators
(Springer India, 2007)We introduce certain linear positive operators and study some approximation properties of these operators in the space of functions, continuous on a compact set, of two variables. We also find the order of this approximation ... -
