Kutta (2S-DIRK) method which is an inherently "oscillation-free" numerical integration method. In order to bring out full accuracy of the 2S-DIRK method, supplementary numerical techniques are required for the representation of voltage sources, current sources and switches. This paper illustrates these techniques with numerical examples.

The seventh order Taylor series approximation is very close to the theoretical value of the function even if it is computed far from the point around which the Taylor series was computed (i.e., (x = pi/2) and (a = 0)). The most common Taylor series approximation is the first order approximation, or linear approximation tuitively, for "smooth" functions the linear …

Representation of a lumped model consisting of a voltage source and a resistor. The lumped-element model (also called lumped-parameter model, or lumped-component model) is a simplified representation of a physical system or circuit that assumes all components are concentrated at a single point and their behavior can be described by idealized mathematical models.
capacitors on the systems are negligent, whereas changing the inductor causes the output to change. The salient features of this algorithm are the inclusion of the parameter variation in the RLC. 1.

difference between the two methods for mitigation of numerical oscillations is that the first is applied in the numeric solution, and the second method is applied directly in the line model.

What is State Space Representation. For state models, the equations are set up into a set of first-order differential equations in terms of chosen state variables, and the outputs are stated in these same state variables. Since the variable elimination is not an integral part of this method, state models can be obtained easily.
Numerical methods are used by engineers and scientists to solve problems. However, numerical methods are just one step in solving an engineering problem.

fast signals, the capacitor "looks" like a short-circuit. But after a while the capacitor''s reservoirs fill, the current stops, and we notice that there really is a break in the circuit. For slow signals, a capacitor "looks" like an open circuit. What is fast, and what is slow? It depends on the capacitor and the rest of the circuit.
