Ultimate Fast Gyrosynchrotron Codes

چکیده
The past decade has seen a dramatic increase of practical applications the microwave gyrosynchrotron emission for plasma diagnostics and three-dimensional modeling solar flares other astrophysical objects. This break-through turned out to become possible due apparently minor, technical development Fast Gyrosynchrotron Codes, which enormously reduced computation time needed calculate single spectrum, while preserving accuracy computation. However, available fast codes are limited in that they could only be used factorized distribution over energy pitch-angle, distributions electrons or pitch-angle number predefined analytical functions. In realistic simulations, these assumptions do not hold; thus, free from mentioned limitations called for. To remedy this situation, we extended our work with an arbitrary input function radiating electrons. We accomplished by implementing described numerically-defined array. addition, removed several improved treatment free-free component. Ultimate Codes presented here allow combination analytically numerically defined distributions, offers most flexible use codes. illustrate code few simple examples.

Turbo - codes : the ultimate error control codes ? by A . Burr
Turbo-codes have attracted a great deal of interest since their discovery in 1993. This paper reviews the reasons for this, in particular their attainment of the ultimate limits of the capacity of a communication channel. The paper describes the two fundamental concepts on which they are based: concatenated coding and iterative decoding. This latter is the real ‘turbo-principle’, which is the r...
متن کاملUltimate Codes: Near-Optimal MDS Array Codes for RAID-6
As modern storage systems have grown in size and complexity, RAID-6 is poised to replace RAID-5 as the dominant form of RAID architectures due to its ability to protect against double disk failures. Many excellent erasure codes specially designed for RAID-6 have emerged in recent years. However, all of them have limitations. In this paper, we present a class of near perfect erasure codes for RA...
متن کاملFast Implementation of the Ultimate Opening
We present an efficient implementation of the ultimate attribute opening operator. In this implementation, the ultimate opening is computed by processing the image maxtree representation. To show the efficiency of this implementation, execution time is given for various images at different scales. A quasi-linear dependency with the number of pixels is observed. This new implementation makes the...
متن کاملFast Projective Reconstruction: Toward Ultimate Efficiency
We accelerate the time-consuming iterations for projective reconstruction, a key component of self-calibration for computing 3-D shapes from feature point tracking over a video sequence. We first summarize the algorithms of the primal and dual methods for projective reconstruction. Then, we replace the eigenvalue computation in each step by the power method. We also accelerate the power method ...
متن کاملFalcon Codes: Fast, Authenticated LT Codes
In this paper, we introduce Falcon codes, a class of authenticated error correcting codes that are based on LT codes [23] and achieve the following properties, for the first time simultaneously: (1) with high probability, they can correct adversarial symbol corruptions in the encoding of a message, and (2) they allow for very efficient encoding and decoding times, even linear in the message len...
