Thin Structures Segmentation Using Anisotropic Neighborhoods

Bayesian and probabilistic models are widely used in image processing to handle noise due to various alteration phenomena. To benefit from the spatial information in a tractable way, Markov Random Fields (MRF) are often assumed with isotropic…

[Technical Report] Multi-frequency calibration for DOA estimation with distributed sensors

In this work, we investigate direction nding in the presence of sensor gain uncertainties and directional perturbations for sensor array processing in a multi-frequency scenario. Specically, we adopt a distributed optimization scheme in which…

Study of structural, magnetic properties and bandgap of spinel Co1−xFe2+xO4 ferrite

Co1−xFe2+xO4 (x = 0.0–0.8) spinel nano ferrite dry gel powders were synthesized by sol gel auto-combustion method. Synthesized samples were investigated by using X-ray diffraction (XRD), magnetic measurements, Ultraviolet–visible (Uv–Vis); Fourier…

Wiring networks diagnosis using time-domain reflectometry and support vector machines

An efficient diagnosis method dedicated to embedded wiring network based on reflectometry technique is developed in this study. The proposed methodology is based on the two complementary steps. In the first step, the time-domain reflectometry (TDR)…

Markov switching autoregressive modeling of wind power forecast errors

Forecast errors constitute the main hurdle to integrating variable renewable energies into electrical power systems. Errors are inherent to forecasting, although their magnitude varies significantly with respect to both the method adopted and the…
