Synthetic circuit elements of higher order with current conveyors

Asia-Pacific Conference on Circuits and Systems, 2003
The design of a synthetic element of higher-order immittance function using transformation circuits is described. A new current conveyor structure for low x-terminal input impedance has been used and its model has been presented. PSpice simulation of a third-order Chebyshev lowpass filter is included.

Rendering higher order finite element surfaces in hardware

Proceedings of the 1st international conference on Computer graphics and interactive techniques in Austalasia and South East Asia - GRAPHITE '03, 2003
Graphics hardware is becoming flexible enough to move more than just the traditional rendering pipeline off the CPU and onto the graphics card. We demonstrate a technique for rendering nonlinear (quadratic in our case) finite element boundaries, deflected by a vector field value and colored by a scalar field value.

Two-Dimensional Higher Order Elements

2014
The triangular elements with quadratic and cubic shape functions in terms of the local area coordinates are presented and coordinate transformation law with the associated Jacobian matrix calculations are given in the chapter. As an application, the Field problem in two dimensions is considered and employing the quadratic triangular element, the ...

Union-Preserving Transformations of Higher Order Surface-Elements

American Journal of Mathematics, 1947
1. Curve-element transformations of the union-preserving type. In 1943, Kasner and De Cicco began the study of transformations in the plaie and in space from differential elements of order n into those of first order.' We have termed such a correspondence union-preserving if it converts every union into a union.
