For five years, Mishra & Koehler conducted an experiment to understand educators’ development of rich technology uses as well as helping them develop their teaching with technology. As a result of this work, they arrived at the Technological, Pedagogical, Content Knowledge (TPCK) model in 2008, later renamed to TPACK.
A useful macroscopic model that combines an electric field with DLA was developed by Niemeyer, Pietronero, and Weismann in 1984, and is known as the dielectric breakdown model (DBM). [ 7 ] Although the electrical breakdown mechanisms of air and PMMA plastic are considerably different, the branching discharges turn out to be related.
Typically, materials used for pattern making are wood, metal or plastics. Wax and Plaster of Paris are also used, but only for specialized applications. Sugar pine wood is the most commonly used material for patterns, primarily because it is soft, light, and easy to work.

Kerr effect (or quadratic electro-optic effect, QEO effect): change in the refractive index proportional to the square of the electric field. All materials display the Kerr effect, with varying magnitudes, but it is generally much weaker than the Pockels effect; electro-gyration: change in the optical activity. Electron-refractive effect or EIPM
The pattern playback [1] [2] is an early talking device that was built by Dr. Franklin S. Cooper and his colleagues, including John M. Borst and Caryl Haskins, at Haskins Laboratories in the late 1940s and completed in 1950. There were several different versions of this hardware device.
Patterns may be drafted on paper or in a computer program designed for patternmaking. Most of the time, in modern American samplerooms, the patternmaker pulls an existing pattern (or block) and makes a modified copy of it to match the new style, either on paper or on computer.
The Jacquard machine (French:) is a device fitted to a loom that simplifies the process of manufacturing textiles with such complex patterns as brocade, damask and matelassé. [3] The resulting ensemble of the loom and Jacquard machine is then called a Jacquard loom .
