  • The acoustic characterisation of Chua’s chaos circuit 
    Doncean, Gheorghe (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2015)
    Chua’s circuit has multiple applications - in politics, economics, telecommunications, technical physics, nanomaterial synthesis, biology - and is of interest thanks to the multitude of adjustment parameters in simulation ...
  • Chromatic kinetics in thermal field 
    Doncean, Gheorghe (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2014)
    The first section of the paper outlines the thermal kinetics of the thermoelectric cell and defines the thermistor as the heating element during the isothermal period. The paper then focuses on uniform wetting and heating ...
  • Colorimetric characterisation of trichromatic RGB digital images. I. comparative HSL colour features 
    Doncean, Gheorghe (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2013)
    The linear and uniform RGB colour space can include up to 255 x 255 x 255 = 16,581,375 colours, far exceeding the capabilities of the human eye in the 400 - 700 nm wavelength interval. In colour rendering technique, each ...
  • Colorimetric characterisation of trichromatic RGB digital images. II. CIE colorimetric characteristics 
    Doncean, Gheorghe (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2013)
    In performing the colour analysis of a particular colour, according to the CIE standards, the CIE xy, CIE ab and CIE uv colour diagrams are used, as derived from the corresponding XYZ, Lab and Luv colour spaces. They ...
  • Colour spaces in scientific research 
    Doncean, Gheorghe (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2012)
    Colour is an individual visual perception that is dependent upon numerous factors. Colour cannot be measured directly unlike the mass of a body or its geometric characteristics (length, width, height). Using the key ...
  • Conditions for obtaining uniform plasma in atmospheric electrical discharge with double barrier (D-DBD) 
    Doncean, Gheorghe (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2014)
    Constructive solutions are presented for a double barrier for plasma-chemical reactor designed to treat multiple: fluid, thin planar dielectric materials etc. In order to obtain a uniformly distributed plasma workload ...
  • Globular laser in/on DBD plasma 
    Doncean, Gheorghe (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2015)
    The paper presents the characteristics of the globular laser generated under resonance conditions. It highlights the diameter and internal architecture featuring spokes and rolling surfaces, depending on whether contact ...
  • Physical and chemical characteristics of water in a microwave field and mass transfer during the drying of dense textiles 
    Doncean, Gheorghe (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2012)
    Microwave drying provides economic advantages based on optimised energy consumption and productivity deriving from the changes in physical and chemical properties of water in a microwave field: heating rate, as influenced ...
