    Notes: [Auszug] The rapid increase in Pseudomonas (Burkholderia) cepacia infection in cystic fibrosis (CF) patients suggests epidemic transmission, but the degree of transmissibility remains controversial as conflicting conclusions have been drawn from studies at different CF centres. This report provides the ...

    Notes: [Auszug] Trichromatic vision in primates is achieved by three genes encoding variants of the photopigment opsin that respond individually to short, medium or long wavelengths of light. It is believed to have originated in simians because so far prosimians (a more primitive group that includes lemurs and ...

    Arbitrary FIR Filter Synthesis Using a Neural Network (1998)
    Springer
    Neural processing letters 8 (1998), S. 9-13 
    Details
    ISSN: 1573-773X
    Keywords: neural network evolutionary optimization ; arbitrary FIR filter synthesis ; eigenproblem
    Source: Springer Online Journal Archives 1860-2000
    Topics: Computer Science
    Notes: Abstract We propose a neural network to synthesize an arbitrary FIR filter in a least square sense. The network can evolve to its steady-states or equilibrium points from any initial state in the magnitude of the circuit's time constant. Under the steady-state, the output of the network is just our designed FIR filter coefficient if a real, symmetric, and positive-definite matrix calculated by the design specifications is directly used as the synaptic strength matrix.

    An Efficient Approach for Computing the RCS of Electrically Large Targets (1999)
    Springer
    International journal of infrared and millimeter waves 20 (1999), S. 2139-2147 
    Details
    ISSN: 1572-9559
    Keywords: Parametric surfaces ; Physical optic ; Radar cross section
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract This paper presents a method for the computation of the monostatic radar cross section (RCS) of electrically large conducting objects modeled by a new kind of parametric surfaces based on trigonometric functions using physical optic (PO) technique. The PO integral on the parametric surfaces is calculated using nine point Gaussian integration. The geometric description using the parametric surfaces is simpler than that using NURBS surfaces. Good agreement with geometric optics (GO) predictions at a millimeter-wave frequency is obtained. RCS results show that the parametric surfaces for the description of objects can be used in RCS computation.

    A Scheme for Analyzing the RCS of a Scale Model Beyond the Size Measureable in the Range of Millimeter-Wave (2000)
    Springer
    International journal of infrared and millimeter waves 21 (2000), S. 1589-1601 
    Details
    ISSN: 1572-9559
    Keywords: radar cross section ; scattered field
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The problem of obtaining the radar cross section (RCS) of a scale model too large to measure in the range of millimeter-wave by measurement is investigated. This topic, to the best of our knowledge, has been little investigated due to its complexity. A scheme named RCS part measurement and synthesis to this problem is developed in this paper. This method combines measurement with theoretical calculation. The first step in using the method is that a scale model is partitioned into several parts measurable. Then the contributions of the sections and shadow region shadowed by all other parts are removed from the measured RCS data of every part. Finally, the scattered fields of all the parts are synthesized to obtain the total RCS of the scale model by means of the technique of relative phase synthesis. A result is presented to illustrate the utility of this scheme.
