In the present paper, we introduce the q-analog of Chlodowsky operators. We study some approximation properties of these new operators, which include the rate of convergence and investigation of the… (More)

Abstract In land seismic surveys, the seismic data are mostly contaminated by ground-roll noise, high amplitude and low frequency. Since the ground-roll is coherent with reflections and depends on… (More)

The present paper deals with the new type of Gamma operators, here we estimate the rate of point wise convergence of these new Gamma type operators L"n for functions with derivatives of bounded… (More)

Abstract Seismic data have still no enough temporal resolution because of band-limited nature of available data even if it is deconvolved. However, lower and higher frequency information belonging to… (More)

In this paper some direct local and global approximation results are obtained for the modified Gamma operators defined by A. Izgi and Buyukyazici (Approximation and rate of approximation on unbounded… (More)

In the present article we investigate both the pointwise convergence and the rate of pointwise convergence of the operators to f(x 0) as (x,λ)→ (x 0,λ 0) in L 1〈 a,b〉 where 〈 a,b〉 is an arbitrary… (More)

In the present paper, we estimate the rate of pointwise convergence of the Chlodowsky type Durrmeyer OperatorsDn(f,x) for functions, defined on the interval (0,bn), (bn ! 1), ex- tending infinity, of… (More)

Abstract In interpretation of seismic data the resolution and smoothness of the envelope of the seismic trace is an important property to have. This paper introduces a new method of envelope… (More)

Time-dependent amplitude and phase information of stacked seismic data are processed independently using complex trace analysis in order to facilitate interpretation by improving resolution and… (More)
