  • An expert system to automate the classification of parts on a single system design documentation

    Modern CAD systems now allow automate most of the stages of design and technological preparation of production . But there is a number of routine procedures. This article is about the details classification operation analysys .
     A review of existing solutions has shown that there are two ways to classify the details. The first - a “manual” characteristics of the classifier, assignment. This is the major method. The second is the expert system "Klassifikator" from the AsconCo., which is based only on the verbal description of the parts and the user selected one of parts from the existing. So that the function of user is to provide the recognition of images patterns.  These methods of pattern recognition  systems are successfully solve complex image recognition task . Analysis of methods of recognition led to the selection of the neural network method for classification of items.
    We want you to use expert system consists of a Hamming neural network emulator and the semantic model of knowledge representation with direct output to solve the problem of classification of parts.
    This combination of neuro-cybernetics and information approach to the creation of an expert system can either automatically determine a part characteristic by its image , or in a semi-automatic mode, prompting the missing information from user.  

    Keywords: expert system, pattern recognition, computer-aided design, neural network classification characteristic details.

  • Catalyst-free thermal synthesis of ZNO nanocrystals from zinc vapor by low temperature

    ZnO nanorod arrays have been synthesized on silicon wafers by chemical vapor deposition (CVD) technique with different  temperature modes, without metal catalyst.  With this method   vertically aligned ZnO nanostructures  were grown at the quite low temperatures.  Modification of the method allowed to place silicon substrates in areas with different  ratios of concentrations of the molecules in the vapor phase. Photoluminescence spectroscopy and electron microscopy studies have shown that morphologies and optical properties of nanorods depends on different ratios of concentrations of the molecules in the vapor phase.

  • Pulsed laser deposition of ZnO nanostructures

    The arrays of ZnO nanorods were obtained on the sapphire substrates by means of pulsed laser deposition under the high pressure of argon. The conditions of synthesis were optimized, and their influence on the morphology of  ZnO nanostructures were revealed. It is shown that the concentration of oxygen vacancies in ZnO nanorods can be changed by regulation of the synthesis temperature from 850 to 915 °. This process can be controlled by the ratio of intensities of the photoluminescence emission in the visible and ultraviolet regions. So, it allows to create nanostructures for UV photodetectors or chemosensors depending on the temperature choice.
