Research


Current research activities include:

Antennas

  • Design, modeling and prototyping of microwave antennas and circuits
  • Wideband and multi-band printed antenna element design
  • Phased arrays

Bioelectromagnetics

  • Impact of 900MHz and 1.8GHz radiation on biological systems cellular mechanisms
  • Post-processing of MRI data

Fuzzy Sets

  • Theoretical and applied aspects of higher-order fuzzy sets (Intuitionistic Fuzzy Sets, Type-2 Fuzzy Sets etc.)
  • Applications of higher-order fuzzy sets to image processing (Intuitionistic Fuzzy Image Processing - IFIP)

Image Processing

  • Image processing using fuzzy sets theory
  • Image processing using higher-order fuzzy sets
  • Image representation via multidimensional directional bases (Wavelets, Ridgelets, Curvelets, Contourlets etc.)
  • Motion detection and estimation in pixel intensity domain and transform domains.

Propagation

  • Development of deterministic propagation prediction model, based on ray-theory and the Uniform Theory of Diffraction (UTD)
  • Development of progressive propagation prediction strategies for ray-tracing planning tools
  • Development of semi-deterministic propagation prediction models, suitable for urban and indoor environment
  • Identification, and Characterization of the scattering effects, typically encountered in the “urban scene”

Speech Synthesis & Speech Recognition

  • Speech Analysis
  • Prosody Modeling
  • Text-to-Speech Synthesis
  • Statistical Methods for Speech Recognition
