In the present paper, by considering the notion of ideals in $MV$-algebras, we study some kinds of ideals in $MV$-algebras and obtain some results on them. For example, we present definition of ultra ideal in $MV$-algebras, and we get some results on it. In fact, by definition of ultra ideals, we present new conditions to have prime ideals, positive implicative ideals and maximal ideals in $MV$...

SUMMARY Traceability codes are used in schemes that prevent illegal redistribution of digital content. In this Letter, we use Chinese Reminder Theorem codes to construct traceability codes. Both the code parameters and the traitor identification process take into account the non-uniformity of the alphabet of Chinese Reminder Theorem codes. Moreover it is shown that the identification process ca...

Cryptography is the practise and study of techniques for secure communication in the presence of third parties. The necessity and the fact that exchanged messages are exposed to other people during the transmission promoted the creation of encryption systems, enabling just the recipients to interpret the exchanged information. In this paper, a particular cryptosystem called Rabin Cryptosystem i...

This article examines the problem of fast RSA encryption with Chinese Reminder Theorem (CRT) immune against hardware fault cryptanalysis. This type of RSA scheme has been widely adopted as a standard implementation in many applications ranging from large servers to tiny smart cards. However, single error in this scheme can totally break the whole RSA scheme by factoring public modulus. It will ...

because of having good performance in cancelling the clutter echoes, pulsed-doppler radar is the best solution in some applications. in this paper a new algorithm for signal design and signal processing in high prf radar is developed. the robust chinese remainder theorem is the basis for estimating the unambiguous ranges in the proposed algorithm. two high prf pulsed-doppler radars are designed...

Residue Number System is a numerical system which arithmetic operations are performed parallelly. One of the main factors that affects the system’s performance is the complexity of reverse converter. It should be noted that the complexity of this part should not affect the earned speed of parallelly performed arithmetic unit. Therefore in this paper a high speed converter for moduli set {2n-1, ...

PRETRIEVE is a belief-network-based, unsolicited information-retrieval system that performs machine learning based on user feedback. We report here on the document-ordering and document-retrieval performance of PRETRIEVE. We developed a test collection of 410 judgments of document utility in a simulated medical order-entry context. We characterized the validity of these judgments, which were el...
