    A numerical study of the Belousov-Zhabotinskii reaction using Galerkin finite element methods (1983)
    Springer
    Journal of mathematical biology 16 (1983), S. 251-260 
    Details
    ISSN: 1432-1416
    Keywords: Travelling fronts ; Parabolic system ; Galerkin finite element methods ; Wave speeds
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Mathematics
    Notes: Abstract The Belousov-Zhabotinskii reaction has been modelled by Field and Noyes [5] as a pair of nonlinear parabolic equations. Previous studies of these, both theoretical and numerical, have assumed wave solutions travelling with constant velocity leading to a simplification of the mathematical model in the form of a system of ordinary differential equations. In the present study a finite element Galerkin method is used directly on the original parabolic system for a range of parameter values.

    Method of quasilinearization and positivity of solutions in abstract cones (1977)
    Springer
    Journal of optimization theory and applications 22 (1977), S. 353-372 
    Details
    ISSN: 1573-2878
    Keywords: Quasilinearization methods ; abstract spaces ; differential equations ; inequality theory
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: Abstract In this paper, the method of quasilinearization is extended to differential equations in Banach spaces using abstract cones. Frequently, it is useful to apply this technique to a comparison system. Several applications are given indicating the flexibility obtained by appropriate choice of the comparison system and cone.

    Synthesis, Properties and Performance of the High Explosive ANTA (1994)
    Weinheim : Wiley-Blackwell
    Propellants, Explosives, Pyrotechnics 19 (1994), S. 174-179 
    Details
    ISSN: 0721-3115
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: 3-Amino-5nitro-1,2,4-triazole(ANTA) was prepared and evaluated in terms of insensitivity and performance. The material is very insensitive to impact and moderately so to thermal stimuli. Performance was found to be inferior to 1,3,5-triamino-2,4,6-trinitrobenzene (TATB). The best synthesis of ANTA is a three-step route using commercially available 3,5-diamino-1,2,4-triazole.

    Nitroureas 1. Synthesis, scale-up and characterization of K-6 (1994)
    Weinheim : Wiley-Blackwell
    Propellants, Explosives, Pyrotechnics 19 (1994), S. 232-239 
    Details
    ISSN: 0721-3115
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: The synthesis and characterization of 2-oxo-1,3,5-trinitro-1,3,5-triazacyclohexane (K-6), a cyclic dinitrourea, is described. The laboratory synthesis was scaled-up to provide 1.6 kilograms of crystalline K-6 which was used for performance testing. K-6 was formulated with 5% Viton A and pressed to 96.5% theoretical maximum density (TMD). Performance measurements in the form of front surface velocity measurements (tantalum plate push) and 1-inch cylinder expansion experiments indicate K-6 will out-perform HMX by 4% at early volume expansions. Thermal response and shock sensitivity experiments on K-6 are also described.
