The Zeckendorf Representation And The Golden Sequence, Martin Bunder, Keith Tognetti Jan 1991

The Zeckendorf Representation And The Golden Sequence, Martin Bunder, Keith Tognetti

Faculty of Engineering and Information Sciences - Papers: Part A

The Zeckendorf representation of a number is simply the representation of that number as the sum of distinct Fibonacci numbers. If the number of terms of this sum is minimized, that representation is unique, as also is the representation when the number of terms is maximized.


Statistical Image Algebra: A Bayesian Approach, Jennifer L. Davidson, Noel A. Cressie Jan 1991

Statistical Image Algebra: A Bayesian Approach, Jennifer L. Davidson, Noel A. Cressie

Faculty of Engineering and Information Sciences - Papers: Part A

A mathematical structure used to express image processing transforms, the AFATL image algebra has proved itself useful in a wide variety of applications. The theoretical foundation for the image algebra includes many important constructs for handling a wide variety of image processing problems: questions relating to linear and nonlinear transforms, including decomposition techniques [9], [5]; mapping of transformations to computer architectures [8], [4]; neural networks [1 1], [6]; recursive transforms [10]; and data manipulation on hexagonal arrays. However, statistical notions have been included only on a very elementary level in [12], and on a more sophisticated level in [2]. In ...


Effect Of Postinfection Application Of Phosphorous (Phosphonic) Acid On The Incidence And Sporulation Of Plasmopara Viticola On Grapevine, T J. Wicks, P A. Magarey, M F. Wachtel, A B. Frensham Jan 1991

Effect Of Postinfection Application Of Phosphorous (Phosphonic) Acid On The Incidence And Sporulation Of Plasmopara Viticola On Grapevine, T J. Wicks, P A. Magarey, M F. Wachtel, A B. Frensham

Faculty of Engineering and Information Sciences - Papers: Part A

Phosphorous acid (H3P03) applied at 1.2 gIL up to 12 days after infection reduced the incidence and severity of Plasmopara vitieola. When applied up to 13 days after infection, H3P03 reduced sporulation. In some experiments, the postinfection activity of H3P03 was better than metalaxyl, while in other experiments it was less effective. Both fungicides applied after infection reduced the incidence and severity of disease on leaves and flower clusters, indicating that postinfection applications should reduce the production of inoculum and the consequent spread of disease within a vineyard. In most cases, the addition of copper oxychloride did not affect ...
