Analysis methods of noise extraction from CT images [PDF]
Journal of Electrical and Electronics Engineering, 2009 This paper presents a comparativeanalysis of the efficiency of certain filters used forextracting the noise from CT (Computer Tomography)images. Appreciation of filtration methods is based onthe use of mean squared error and direct visualizationof the ...

Advanced Engineering Materials, EarlyView.A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation
