چکیده
We describe a modiied Sag-Szekeres multidimensional quadrature algorithm and discuss its implementation as a general-purpose library procedure on serial and parallel architectures. Examples illustrate its eeectiveness for both smooth and singular integrands.

Investigation of Effect of Number of Lifters on Performance of Pilot-Scale SAG Mills Using Discrete Element Method
The number of lifters of mill shell liners, mill rotation speed, and filling percentage of grinding media are three of the most important parameters influencing the charge behavior and the trajectory of ball motion inside the SAG mills, and consequently, their performance. In this paper, the milling operation of pilot-scale SAG mills using the discrete element method (DEM) is investigated. Firs...
متن کاملExact Implementation of Multiple Initial Conditions in the DQ Solution of Higher-Order ODEs
The differential quadrature method (DQM) is one of the most elegant and useful approximate methods for solving initial and/or boundary value problems. It is easy to use and also straightforward to implement. However, the conventional DQM is well-known to have some difficulty in implementing multiple initial and/or boundary conditions at a given discrete point. To overcome this difficulty, this ...
متن کاملA Simple and Systematic Approach for Implementing Boundary Conditions in the Differential Quadrature Free and Forced Vibration Analysis of Beams and Rectangular Plates
This paper presents a simple and systematic way for imposing boundary conditions in the differential quadrature free and forced vibration analysis of beams and rectangular plates. First, the Dirichlet- and Neumann-type boundary conditions of the beam (or plate) are expressed as differential quadrature analog equations at the grid points on or near the boundaries. Then, similar to CBCGE (direct ...
متن کاملA New Control for Series Compensation of UPQC to Improve Voltage Sag/Swell
Voltage sag/swell is one of the most frequently power quality problems which affects the power systems with sensitive loads. The unified power quality conditioner (UPQC) is capable of mitigating the effect of voltage sag/swell at the load or point of common coupling (PCC). In this paper, a new control of UPQC is proposed based on combining the sag detection and voltage injection established on ...

One of the important power quality issues is voltage sag. The voltage sag can generate many undesirable effects on electrical equipment. The major effect of voltage sag on electrical machine is torque pulsations after and during voltage sag. In this paper, using a simple theoretical analysis called stator flux trajectory method, producing manner of the torque pulsations and the impact of ...
