When a target is marked by a designator, the beam is invisible and does not shine continuously. Instead, a series of coded laser pulses, also called PRF codes (pulse repetition frequency), are fired at the target.
List of episodes. " Brother's Little Helper " is the second episode of the eleventh season of the American animated television series The Simpsons. It first aired on the Fox network in the United States on October 3, 1999. In the episode, Bart floods the school gymnasium and the schoolyard, which prompts the school's principal Seymour Skinner ...
In the United States a longer duty cycle is used, 50% for battery -powered buoys (20 seconds on, 20 seconds off) and 75% for on-shore beacons. Ramarks are wide-band beacons which transmit continuously on the radar bands without having to be triggered by an incoming radar signal.
The ORF Finder (Open Reading Frame Finder) is a graphical analysis tool which finds all open reading frames of a selectable minimum size in a user's sequence or in a sequence already in the database. This tool identifies all open reading frames using the standard or alternative genetic codes.
Spellbound. (2002 film) Spellbound is a 2002 American documentary that was directed by Jeffrey Blitz. The film follows eight competitors in the 1999 Scripps National Spelling Bee. The film received positive reviews and won several awards, including a nomination for the Academy Award for Best Documentary Feature .
At very low energies, space charge has a large effect on a particle beam and thus becomes hard to calculate. See below for a list of programs that can handle low energy space charge forces. Synchrotron radiation effects. Can simulate the effect of synchrotron radiation emission on the particles being tracked.
Monte Carlo N-Particle Transport Code. Monte Carlo N-Particle Transport ( MCNP) [2] is a general-purpose, continuous-energy, generalized-geometry, time-dependent, Monte Carlo radiation transport code designed to track many particle types over broad ranges of energies and is developed by Los Alamos National Laboratory.
An example of a stabilizer code is the five qubit [[,,]] stabilizer code. It encodes k = 1 {\displaystyle k=1} logical qubit into n = 5 {\displaystyle n=5} physical qubits and protects against an arbitrary single-qubit error.

Refractive index. A ray of light being refracted through a glass slab. In optics, the refractive index (or refraction index) of an optical medium is a dimensionless number that gives the indication of the light bending ability of that medium. Refraction of a light ray. The refractive index determines how much the path of light is bent, or ...
