introduction in remote sensing studies, especially those in which multi-spectral image data are used, (i.e., landsat-7 enhanced thematic mapper), various statistical methods are often applied for image enhancement and feature extraction (reddy, 2008). principal component analysis is a multivariate statistical technique which is frequently used in multidimensional data analysis. this method atte...

Content description has become a topic of interest for many researchers in the audiovisual field [1][2]. While manual annotation has been used for many years in different applications, the focus now is on finding automatic contentextraction and content-navigation tools. An increasing number of projects, in some of which we are actively involved, focus on the extraction of meaningful features fr...

Based on the accumulated data, FTIR spectroscopy seems to be a highly sensitive tool in cervical cancer diagnosis. We, therefore, employed this technique in a screening type of research here in Tehran. The purpose of this study was to look for the spectral pattern differences between normal and malignant cervix samples in Iranian women. Through formal and informal announcements, all gynecology ...

Introduction: Quantitative assessments of the effects induced by repetitive transcranial magnetic stimulation (rTMS) are crucial to develop more efficient and personalized treatments. Objectives: To determine the spectral powers of different subbands of EEG correlated with treatment response to rTMS.   Materials and Methods: the spectral powers of different...

Introduction: Purkinje Cell (PC) output displays a complex firing pattern consisting of high frequency sodium spikes and low frequency calcium spikes, and disruption in this firing behavior may contribute to cerebellar ataxia. Riluzole, neuroprotective agent, has been demonstrated to have neuroprotective effects in cerebellar ataxia. Here, the spectral analysis of PCs firing in control, 3-acety...
