Research ArticleOpen accessIn the abstractFactors Affecting the Oxygenation Capacity of Disc Aerators in an Oxidation Ditch SystemAbdel Ghaly, Skai EdwardsProblem statement: The use of aerobic biological methods for the treatment of livestock wastes has resulted in a proliferation of mechanical aeration devices to accomplish the desired treatment. The oxidation ditch system with disc aerators is among the aerobic systems that have been used to treat livestock waste. The main objectives of this study were to investigate the effects of … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 7,539 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Improved Binary Method for Scalar Multiplication in Elliptic Curve CryptographyM. A. Mohamed, M.R. Md Said, K.A. Mohd Atan, Z. Ahmad ZulkarnainProblem statement: Until recently, many addition chain techniques constructed to support scalar multiplication operation have been proposed tailored to limited computational resources. In securing the efficiency of ECC point operation, the combinations of the two basic operations, point addition and doubling are mostly implemented. Using binary method, the operation of doubling depends solely on the length of binary representation itself, … …Journal of Mathematics and Statistics, Vol. 6, Issue 1 · 31 Mar 2010 · 7,712 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Computation Algorithm for a Cryptosystem Based on Lucas FunctionsMohamed Othman, Esam M. Abulhirat, Zulkarnain Md Ali et al.Most of public-key cryptosystems rely on one-way functions. The cryptosystems can be used to encrypt and sign messages. The LUC Cryptosystem is a cryptosystem based on Lucas Functions. The encryption process used a public key which was known publicly and the decryption used a private key which was known only by sender and receiver of the messages. The performance of … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 6,941 accessesView PDFCite
