    Elastic properties of rigid fiber-reinforced composites (1995)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 77 (1995), S. 4349-4360 
    Details
    ISSN: 1089-7550
    Quelle: AIP Digital Archive
    Thema: Physik
    Notizen: We study the elastic properties of rigid fiber-reinforced composites with perfect bonding between fibers and matrix, and also with sliding boundary conditions. In the dilute region, there exists an exact analytical solution. Around the rigidity threshold we find the elastic moduli and Poisson's ratio by decomposing the deformation into a compression mode and a rotation mode. For perfect bonding, both modes are important, whereas only the compression mode is operative for sliding boundary conditions. We employ the digital-image-based method and a finite element analysis to perform computer simulations which confirm our analytical predictions. © 1995 American Institute of Physics.

    Resistivity of boron-doped diamond microcrystals (1998)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 72 (1998), S. 2445-2447 
    Details
    ISSN: 1077-3118
    Quelle: AIP Digital Archive
    Thema: Physik
    Notizen: We describe measurements of the electrical resistivity of micron-size crystallites of boron-doped diamond. Electron-beam lithography was employed for writing sample-specific contacts on small, well-faceted diamond crystals grown by chemical-vapor deposition on silicon substrates. After generating a three-dimensional computer model of the crystallite, a finite-element analysis was used to calculate the internal electrostatic potential distribution. Multiterminal resistance measurements, in conjunction with a computed geometrical factor, enabled the absolute resistivity to be determined. We find that the resistivities obtained from two different crystallites agree to better than 10%. The results are compared with transport measurements on a large-area homoepitaxial diamond film grown simultaneously with the crystallites. This method can be generalized to obtain electrical transport properties of other small, irregularly shaped samples. © 1998 American Institute of Physics.

    DETERMINATION OF POSITION OF A POINT-OBJECT BY TRIANGULATION IN RECTANGULAR COORDINATES (1960)
    Oxford, UK : Blackwell Publishing Ltd
    The @photogrammetric record 3 (1960), S. 0 
    Details
    ISSN: 1477-9730
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Architektur, Bauingenieurwesen, Vermessung
    Notizen: A theory is presented for determining the position of an aerial point-object from observations of its direction from several ground-stations. The criterion under which the position coordinates are determined is that the sum of the squares of the perpendicular distances of the object from the various observed directions to it should be a minimum. The statistical distribution of the observations is considered, and the theory developed for estimating the standard deviations of the object's coordinates. The relevant equations have been programmed for evaluation by the Pegasus electronic computer.

    Analysing partitioning in plants (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Plant, cell & environment 6 (1983), S. 0 
    Details
    ISSN: 1365-3040
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: Abstract. Our understanding of the control of partitioning in plants and crops is confounded by unsatisfactory and incomplete description of the phenomenon. This paper attempts to improve upon this state of affairs by taking a fresh look at the concepts and the terms we use.While the continued usefulness in general discussion of the popular concepts of source, path and sink and of limitation is recognized, for analysing carbon flows we propose a separate, more practicable and higher level form of description based on a pool: process concept. This is similar to those used to describe the flows of other things in nature. In our analysis of competition between pools, the constant properties pool permeance and pool potential determine partitioning which is a function of the single variable plant potential. A simple phenomenological model embodying them is developed. Because our scheme is less demanding of experimental technique than some, its wide application seems feasible, extending even to the analysis of conventional crop growth measurements. The paper concludes by indicating briefly the sorts of physiological factors which could give rise to these phenomenological properties.

    Correction of infra-red gas analyser readings for changes in reference tube CO2 concentration (1978)
    Oxford, UK : Blackwell Publishing Ltd
    Plant, cell & environment 1 (1978), S. 0 
    Details
    ISSN: 1365-3040
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: Abstract The theoretical basis for correcting infra-red gas analyser readings for changes in reference tube CO2 concentration is developed, but in practice the corrections made are empirical. Analyser gain (GA) is related to reference tube concentration (A) in hyperbolic manner. The constants in the equation are determined by plotting 1/GA against A. Calibration and operating procedure for a particular type of analyser are described and a numerical example given.
