Ziegler Wax Embryo Models

Three-dimensional anatomical models have long been essential to the learning of science and lend a sense of ?control? to those practicing in the field. As the development of embryology [4] grew in importance during the late 1800s, so did the need for models to show intricate details of embryos. Embryologists such as Wilhelm His [5], Ernst Haeckel [6], and Oscar Hertwig all initially constructed...

Pid Controller Design by Modified Ziegler-nichols Method

The paper presents PID controller design using modification of the Aström and Hägglund’s generalized Ziegler-Nichols rules. The design procedure consists in shifting the plant critical point into a specific point. Its position is defined by desired performance specification in term of achieving maximum overshoot and specified settling time of the closed-loop response or phase margin. The method...
