eighteen primiparous rabbit does comprising of six per breed of new zealand white (nzw), chinchilla (cc) and dutch belted (db). they were randomly allocated to three rebreeding interval groups of 7, 14 and 21 days postpartum. three breeding males, one per breed were used giving a total of 21 rabbits. significant (p

In modern large-scale storage systems, locally repairable codes(LRCs) improve the repair efficiency when node failure occurs. This work discusses several new methods for constructing LRCs with small localities using generator and parity-check matrices approach. Many have been found, all distance-optimal (d-optimal) or best-known (BK). Based on newly obtained known results, a database presenting...

We investigate how sensitive Gallager’s codes are, when decoded by the sum-product algorithm, to the assumed noise level. We have found a remarkably simple function that fits the empirical results as a function of the actual noise level at both high and low noise levels. A linear code may be described in terms of a generator matrix G or in terms of a parity check matrix H, which satisfies Hx = ...

Since the introduction of public key cryptography in the 70’s [1], many cryptosystems have been proposed and many cryptographic schemes have been broken. The most used cryptosystems rely on number theory problem like the factorization problem [3] and the discrete logarithm over suitable group [2]. The McEliece cryptosystem [5] and the Neiderreiter variante [6] rely on coding theory, they are on...

We report the empirical performance of Gallager's low density parity check codes on Gaus-sian channels. We show that performance substantially better than that of standard convolu-tional and concatenated codes can be achieved; indeed the performance is almost as close to the Shannon limit as that of Turbo codes. A linear code may be described in terms of a generator matrix G or in terms of a pa...

osteoporosis is considered as an important public health problem especially in postmenopausal women. there are some hypotheses support the contributory effect of pregnancy and lactation on osteoporosis later in life. high calcium demand during pregnancy and lactation and low estrogenic state support those hypotheses. numerous studies have investigated on the issue but there is no consensus abou...

Reversible logic is one of the emerging fields of research in the areas of low power computation, Optical information processing, Fault tolerant system, bio information, quantum computation and nanotechnology. ALU is the most vital component of any processing system and need to consume as much less energy as possible in the mean while must be resistant to faults. In this paper the design of a f...
