    Contour plotting from arbitrarily spaced data points within a region of arbitrary space
    (Australian Atomic Energy Commission, 1975-10) Davidson, MR
    A triangular mesh with data points as vertices is determined. Points on the contours are calculated by linear interpolation along triangle sides. Allowance for general boundary shapes gives the method applications in physics and engineering.

    Software implementation of the knapsack public key cryptographic system
    (Australian Atomic Energy Commission, 1981-12) Davidson, MR; Backstrom, RP
    A software implementation of the Merkle and Hellman public key crytographic system is described. The corresponding subroutines KEYGEN, ENCRYPT, DECRYPT are designed for convenient use on the AAEC central computer and provide the means for more secure disk storage of data.

    A theoretical study of mass transfer between tissue and blood at the apex of a branched blood vessel
    (Australian Atomic Energy Commission, 1978-01) Davidson, MR
    Simplified model of diffusion of inflammatory products, controlled by shear dependent permeability of the endothelium, is proposed to account for the localisation of a medial gap (caused by tissue breakdown) at a bifurcation apex, the endothelial barrier being intact at this stage. For the later stage where the artery wall is broken, a diffusion boundary layer model is proposed which predicts that, in a particular case, the diffusion flux through the break is about 400 times larger than the flux which would exist if the wall was intact at that point, and at least 40 times the down-stream flux for a shear stress of 300 dynes/cm2.
