    Modal disparity and its experimental verification by Issa, Jimmy

    Published 2008
    “…For a given structure, the concept of modal disparity describes the structure's ability to generate significant changes in the mode shapes by some type of on-the-fly structural modification. In the present study we consider a vibrating beam that experiences a controlled stiffness change, induced by the activation and deactivation of an electromagnetic brake that causes a spatially localized change in the bending stiffness. …”

    Attacking ElGamal based cryptographic algorithms using Pollard's rho algorithm by El-Kassar, A. N.

    Published 2005
    “…El-Kassar et al. and El-Kassar and Haraty modified the ElGamal public-key encryption scheme from the domain of natural integers, Z, to two principal ideal domains, namely the domain of Gaussian integers, Z[i], and the domain of the rings of polynomials over finite fields, F[x], by extending the arithmetic needed for the modifications to these domains. In this work we implement the classical and modified ElGamal cryptosystem to compare and to test their functionality, reliability and security. …”

    Analysis of the two microsatellite repeat polymorphisms of the factor VIII gene in the Turkish population by El Maarri, Osman

    Published 1998
    “…The additional use of the two microsatellite repeat polymorphisms with the previously established informative markers has been accepted as the most effective strategy in DNA diagnosis by linkage analysis for the assessment of haemophilia A carriers and affected fetuses in the Turkish population. The modifications adopted in this study for the multiplex PCR analysis of the microsatellite repeat polymorphism eliminated the use of radioactivity and sequencing gels, reducing cost and labour.…”
