Functional Modeling of Astrocytes in Synchronization of Neuronal Cells

Mahmoud Amiri; Fariba Bahrami; Mahyar Janahmadi

Volume 4, Issue 2 , June 2010, Pages 83-96

  Based on the neurophysiologic findings, astrocytes provide not only structural and metabolic supports for the nervous system but also they are active partners in neuronal activities and synaptic transmissions. In the present study, we improved two biologically plausible cortical and thalamocortical neural ...  Read More

Assessment of Time, Frequency, and Wavelet Packet Transform Features Extracted from EEG for Sleep Staging using Self Organizing Maps (SOM)

Faride Ebrahimi; Mohammad Mikaili

Volume 4, Issue 2 , June 2010, Pages 97-108

  Different biological signals including EEG, EOG, and EMG are recorded in sleep labs to diagnose sleep disorders. Data recorded during sleep is usually analyzed by sleep specialists visually. Since the sleep data is usually recorded for a long time period- namely a whole night- its visual inspection and ...  Read More

Kinematical Modeling of the Writing Process using Model Predictive Control

Mehdi Borjkhani; Farzad Towhidkhah

Volume 4, Issue 2 , June 2010, Pages 109-122

  Writing is one of the high practiced and complex movement skills of human. Most of the proposed models for writing are bottom-up models, and therefore they could not reflect the biological aspects of movements in this process. Also there is not any model for illustrating the role of different parts of ...  Read More

Real-Time Classification of Surface Electromyogram Signal using Correntropy

Mohammad Mehdi Ramezani; Ahmad Reza Sharafat

Volume 4, Issue 2 , June 2010, Pages 123-134

  In this paper, we propose a novel approach for classification of surface electromyogram (sEMG) signal with a view to controlling myoelectric prosthetic devices. The sEMG signal generated during isometric contraction is modeled by a stochastic process whose probability density function (PDF) is non- Gaussian ...  Read More

Comparison of Function Features using Modified DTW for Dynamic Signature Verification

Saeed Rashidi; Ali Fallah; Farzad Towhidkhah

Volume 4, Issue 2 , June 2010, Pages 135-148

  Many methods are introduced for estimating the similarities or differences of time signals. One of theses methods, DTW algorithm, is also a utility for other domains including classification, data mining and matching regions between two time signals. DTW algorithm minimizes points distance between two ...  Read More

Analysis of Echocardiography Images using Manifold Learning

Parisa Gifani; Hamid Behnam; Zahra Alizadeh Sani

Volume 4, Issue 2 , June 2010, Pages 149-160

  Dimensionality reduction is an important task in machine learning, to simplify data mining, image processing, classification and visualization of high-dimensional data by mitigating undesired properties of high-dimensional spaces. Manifold learning is a relatively new approach to nonlinear dimensionality ...  Read More

Evaluation of Electromagnetic Radiations (1.5 Tesla) Effect on Liver Functional Tests and Histometery of Liver in Adult Male Rats

Jafar Ai; Saeed Sarkar; Mohammad Ali Oghabian

Volume 4, Issue 2 , June 2010, Pages 161-166

  Various reviews have shown that strong electromagnetic fields have negative effects on human health. This study focused on the effect of MRI radiation on liver functional test histometery of liver in adult male rats. For this purpose, we used an MRI device that could produce 1.5 T electromagnetic radiations, ...  Read More
