A bit serial architecture is used which reduces the interconnect complexity in fully parallel low density parity check (LDPC) decoder. This can achieve better error correcting performance when the code length is moderate. By using a new approximation to the check update function in the Minsum decoding algorithm, the implementation is simplified. This new check update rule finds only the absolute minimum...
We aim to develop an expert system (ES) to the farmers in Meghalaya state for managing rice diseases. The rice diseases prevailing in this area were identified and confirmed after discussion with the domain experts and interacting with the farmers through structured interview schedule. The diagnosed rice diseases were Blast (Pyricularia grisea), Brown Spot (Drechslera oryzae), Sheath Rot (Sarocladium...
Public Key Cryptosystem came into existence after 1975. Since then a large number of research has been conducted in this area. It is based on number theory and exploits the features of computationally hard problems, namely integer factorization, discrete logarithmic problem to name a few. In this paper we describe a public-key cryptosystem. The basis of the design is derived from first version of...
