There has been a dramatic change in the field of field of telelcommunication service. M-ary Quadrature Amplitude modulation and Quadrature Phase shift Keying (QPSK) modulation schemes are considered in Wideband code Division Multiple Access(WCDMA) system. Here we are using MATLAB for simulation and evaluation of BER ( Bit Error Rate )and SNR(Siganl to Noise Ratio). There is analysis of Quadratu...

in this study, the vibration of cracked plates is investigated using the differential quadrature method and experimental modal analysis. the crack, which is assumed to be open, is modeled by the extended rotational spring. with its finite length, the crack divides the plate into six segments. then, the differential quadrature is applied to the governing differential equations of motion and the ...

Abstract—This paper deals with efficient quadrature formulas involving functions that are observed only at fixed sampling points. The approach that we develop is derived from efficient continuous quadrature formulas, such as Gauss-Legendre or Clenshaw-Curtis quadrature. We select nodes at sampling positions that are as close as possible to those of the associated classical quadrature and we upd...

Objectives: ACL reconstruction using hamstring autograft (HA) has been found to have a high re-tear rate in risk patients including those with Pivot shift of 2 or higher and generalized ligamentous laxity (GLL). Because this, the use lateral extra-articular tenodesis (LET) gained traction sports community. Several studies shown lower graft re-tears addition LET is felt by many be necessary when...

In this paper a brief historical survey of the development of quadrature rules with multiple nodes and the maximal algebraic degree of exactness is given. The natural generalization of such rules are quadrature rules with multiple nodes and the maximal degree of exactness in some functional spaces that are different from the space of algebraic polynomial. For that purpose we present a generaliz...

In recent years a number of authors have considered an error analysis for quadrature rules of Newton-Cotes type. In particular, the mid-point, trapezoid and Simpson rules have been investigated more recently ([2], [4], [5], [6], [11]) with the view of obtaining bounds on the quadrature rule in terms of a variety of norms involving, at most, the first derivative. In the mentioned papers explicit...

In this paper, we propose a Modified nested sparse grid based Adaptive Stochastic Collocation Method (MASCM) for block-based Statistical Static Timing Analysis (SSTA). The proposed MASCM employs an improved adaptive strategy derived from the existing Adaptive Stochastic Collocation Method (ASCM) to approximate the key operator MAX during timing analysis. In contrast to ASCM which uses non-neste...
