61Frieze group — A frieze group is a mathematical concept to classify designs on two dimensional surfaces which are repetitive in one direction, based on the symmetries in the pattern. Such patterns occur frequently in architecture and decorative art. The… …
62SMA connector — SMA ( SubMiniature version A ) connectors are coaxial RF connectors developed in the 1960s as a minimal connector interface for coaxial cable with a screw type coupling mechanism. The connector has a 50 Ω impedance. It offers excellent electrical …

64Statically indeterminate — In statics, a structure is statically indeterminate when the static equilibrium equations are not sufficient for determining the internal forces and reactions on that structure.Based on Newton s laws of motion, the equilibrium equations available …
65Maximum length sequence — A maximum length sequence (MLS) is a type of pseudorandom binary sequence. They are bit sequences generated using maximal linear feedback shift registers and are so called because they are periodic and reproduce every binary sequence that can be… …
66Polymer solar cell — Polymer solar cells are a type of organic solar cell: they produce electricity from sunlight. A relatively novel technology, they are being researched by universities, national laboratories and several companies around the world. Device physics… …
67Optical axis gratings — (OAGs) are gratings of optical axis of a birefringent material. In OAGs, the birefringence of the material is constant, while the direction of optical axis is periodically modulated in a fixed direction. In this way they are different from the… …
68Brake-by-wire — Drive by wire technology in automotive industry replaces the traditional mechanical and hydraulic control systems with electronic control systems using electromechanical actuators and human machine interfaces such as pedal and steering feel… …
69Oscillator Toda — is special kind of nonlinear oscillator; it is vulgarization of the Toda field theory, which refers to a continuous limit of Toda s chain, of chain of particles, with exponential potential of interaction between neighbors cite journal|… …
70Self-pulsation — takes place at the beginning of laser action.As the pump is switched on, the gainin the active medium rises and exceeds the steady state value. The number of photons in the cavity increases, depleting the gain below the steady state value, and so …
