abstract although flourishing research has been devoted to research on article abstracts, more studies are needed to unpack the relationship between rhetorical moves and their associated linguistic and rhetorical features (e.g., metadiscourse). to underpin this relationship, the current study analyzed a total of 60 research article abstracts written in english by two cultural groups in three di...

the dna microarray is an important technique that allows researchers to analyze many gene expression data in parallel. although the data can be more significant if they come out of separate experiments, one of the most challenging phases in the microarray context is the integration of separate expression level datasets that have gathered through different techniques. in this paper, we present a...

one of the challenging issues in managing the existing large digital image libraries and databases is content based image retrieval (cbir). the accuracy of image retrieval methods in cbir is subject to effective extraction of image features such as color, texture, and shape. in this paper, we propose a new image retrieval method using contourlet transform coefficients to index texture of the im...

objectives: semantic feature analysis was designed to improve lexical retrieval of aphasic patients via activation of semantic networks of the words. in this approach, the anomic patients are cured with semantic information to assist oral naming. the purpose of this study was to examine the effects of semantic feature analysis treatment on anomia of two nonfluent aphasic patients. methods: a si...

Background: Electromyographic (EMG) signal decomposition is the process by which an EMG signal is decomposed into its constituent motor unit potential trains (MUPTs). A major step in EMG decomposition is feature extraction in which each detected motor unit potential (MUP) is represented by a feature vector. As with any other pattern recognition system, feature extraction has a significant impac...

In a prospective clinical trial, the incidence of scrotal tongue in psoriatic patients was studied. One hundred psoriatics and the same number of non-psoriatic individuals were evaluated for the incidence of fissured tongue, age, duration of illness, and clinical types of psoriasis. In this study 49 psoriatic patients (49%) and 28 non-psoriatic persons (28%) had fissured tongue. The most c...

splenic hamartoma is an unusual accidental finding with non-neoplastic feature that may be incidentally diagnosed because of its compression effect on surrounding organs. the predominant pathological feature leading diagnosis is circumscribed, un-encapsulated bulging nodules with focal fibrosis or cyst. the histopathological feature of splenic hamartoma is the positivity for cd8, and occasional...

In this paper, a feature-based technique for the camera pose estimation in a sequence of wide-baseline images has been proposed. Camera pose estimation is an important issue in many computer vision and robotics applications, such as, augmented reality and visual SLAM. The proposed method can track captured images taken by hand-held camera in room-sized workspaces with maximum scene depth of 3-4...

Image registration is a crucial step in most image processing tasks for which the final result is achieved from a combination of various resources. In general, the majority of registration methods consist of the following four steps: feature extraction, feature matching, transform modeling, and finally image resampling. As the accuracy of a registration process is highly dependent to the fe...

Dependency parser is one of the most important fundamental tools in the natural language processing, which extracts structure of sentences and determines the relations between words based on the dependency grammar. The dependency parser is proper for free order languages, such as Persian. In this paper, data-driven dependency parser has been developed with the help of phrase-structure parser fo...
