Assessing Brain Pathophysiology through Non-Linear Analysis of MEG in Ιdiopathic Generalized Epilepsy Cases
Non-Linear Analysis MEG IGE
2013/1/29
Background: Non-linear signal analysis has proven to be a technique that is capable of revealing qualitative and quan- titative differentiations between different dynamical systems (biological or othe...
Two-Dimensional Orthogonal Filter-Banks and Wavelets with Linear Phase
Filter banks linear phase symmetry 2-D wavelets wavelets
2010/1/7
Two-dimensional (2-D) compactly supported, orthogonal wavelets and filter banks having linear phase are presented. Two cases are discussed: wavelets with two-fold symmetry (centrosymmetric) and wavel...

Study of age-related changes in postural control during quiet standing through Linear Discriminant Analysis
age-related changes postural control Linear Discriminant Analysis
2010/2/25
These results show that the analysis of features computed from the displacement of the COP are of great importance in studies trying to understand the ageing process. In particular, the LDA-value show...
Non-linear dielectric spectroscopy of microbiological suspensions
Non-linear dielectric spectroscopy microbiological suspensions
2010/2/25
Contrary to previous assertions, no repeatable dielectric non-linearity was exhibited in the bulk suspensions tested under the field and frequency condition reported with this recently designed analyz...
Progressive Magnetic Resonance Image Reconstruction Based on Iterative Solution of a Sparse Linear System
Image Reconstruction Sparse Linear System
2009/9/8
Image reconstruction from nonuniformly sampled spatial frequency domain data is an important problem that arises in computed imaging. Current reconstruction techniques suffer from limitations in their...
Experimental Investigation of Angular Stackgram Filtering for Noise Reduction of SPECT Projection Data: Study with Linear and Nonlinear Filters
SPECT Projection Data Nonlinear Filters
2009/9/7
We discuss data filtering prior to image reconstruction. For this kind of filtering, the radial direction of the sinogram is routinely employed. Recently, we have introduced an alternative approach to...
A Penalized Linear and Nonlinear Combined Conjugate Gradient Method for the Reconstruction of Fluorescence Molecular Tomography
Fluorescence Molecular Tomography A Penalized Linear
2009/9/7
Conjugate gradient method is verified to be efficient for nonlinear optimization problems of large-dimension data. In this paper, a penalized linear and nonlinear combined conjugate gradient method fo...
Clustering-Based Linear Least Square Fitting Method for Generation of Parametric Images in Dynamic FDG PET Studies
Parametric Images Dynamic FDG PET Studies
2009/9/7
Parametric images generated from dynamic positron emission tomography (PET) studies are useful for presenting functional/biological information in the 3-dimensional space, but usually suffer from thei...
Development of an Internal Observation System for Biological Samples Using a Linear Micro-slicer
automation image processing internal constituents 3D visualization
2009/6/9
An image scanner (contact image sensor) was attached in the system to obtain 2-dimensional images from the sliced sample, not from the sliced section. By using an image scanner called a micro-slicer i...
A two-dimensional mathematical model of non-linear dual-sorption of percutaneous drug absorption
non-linear dual-sorption percutaneous drug absorption
2010/2/26
Based on the various values of the parameter, C, conclusions are drawn about (1) flow rate of the drug in different regions of the skin, (2) shape of the concentration profiles, (3) the time required ...
