    Dual extremum principles relating to an optimal filter (1980)
    Springer
    Journal of optimization theory and applications 30 (1980), S. 583-588 
    Details
    ISSN: 1573-2878
    Keywords: Filtering theory ; duality theory ; optimal filters ; dual extremum principles
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: Abstract We obtain here a variational principle characterizing an optimal filter. This variational principle is dual to the one obtained by Berkovitz and Pollard in Ref. 2.

    Sharp dual estimates for conductance of an optimal circular cooling fin (1976)
    Springer
    Journal of optimization theory and applications 19 (1976), S. 565-575 
    Details
    ISSN: 1573-2878
    Keywords: Calculus of variations ; heat transfer ; duality theory ; minimax problems ; differential equations
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: Abstract A cooling fin attached to a cylinder of circular cross section is considered. We obtain sharp upper and lower estimates for the maximum heat dissipation under the constraint that the total weight of the fin should not exceed a given bound. It is assumed that the boundary of the cylinder has a constant temperature and that Newton's law of cooling holds.
