    Representing an ordered set as the intersection of super greedy linear extensions (1987)
    Springer
    Order 4 (1987), S. 293-311

    ISSN: 1572-9273

    Notes: Abstract A linear extension [x 1〈x2〈...〈xt] of a finite ordered set P=(P, 〈) is super greedy if it can be obtained using the following procedure: Choose x 1 to be a minimal element of P; suppose x 1,...,x i have been chosen; define p(x) to be the largest j≤i such that x j〈x if such a j exists and 0 otherwise; choose x i+1 to be a minimal element of P-{ x 1,...,x i} which maximizes p. Every finite ordered set P can be represented as the intersection of a family of super greedy linear extensions, called a super greedy realizer of P. The super greedy dimension of P is the minimum cardinality of a super greedy realizer of P. Best possible upper bounds for the super greedy dimension of P are derived in terms of |P-A| and width (P-A), where A is a maximal antichain.

    Measurement of Thermal Diffusivity of Thermal Control Coatings by the Flash Method Using Two-Layer Composite Sample1 (2000)
    Springer

    Notes: Abstract The thermal diffusivity of brittle coatings cannot be measured by the flash method directly because of the difficulty of preparing free-standing samples. Adopting the flash method using a two-layer composite sample, it is possible to measure thermal diffusivity if the radiant pulse is well defined and good thermal contact on the interface of the composite sample can be ensured. Using an equilateral trapezoidal pulse of an Nd-glass laser measuring the dimensionless temperature history of the rear face of the sample, we determined the thermal diffusivity of thermal control coatings in the temperature range of 80 to 200°C. The results for different thicknesses of substrate showed that the thermal contact resistance of the interface can be neglected.

    Thermal Diffusivity Measurement of Diamond Films1 (2000)
    Springer
    International journal of thermophysics 21 (2000), S. 479-485

    ISSN: 1572-9567
    Keywords: diamond ; film ; flash method ; thermal diffusivity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract This paper discusses the short-pulse-flash method developed for thermal diffusivity measurements on thin films. Two kinds of CVD diamond film have been prepared, and their thermal diffusivity in the perpendicular direction has been measured with this method. The measurement errors caused by the surface coating are discussed.

    Measurement of thermal diffusivity by the flash method for a two-layer composite sample in the case of triangular pulse (1986)
    Springer

    Notes: Abstract A method for measuring thermal diffusivity in one of the layers of a two-layer composite sample has been described. The heat transfer problem of a two-layer sample associated with pulse thermal diffusivity measurements has been analyzed for two cases: exponential and square-wave pulses. According to our measurements, a triangular heat-pulse function approximates reasonably well the output of the Nd-glass laser. In this paper, an expression is derived for the temperature transient at the rear face of two-layer sample being subjected to a triangular heat-pulse input on the front face. The analytical solution of the problem forms the basis of our method of data reduction. This solution has been programmed for computer processing of the data. The method described here has been successfully tested by limited measurements on copper and iron.
