The aim of this study is to investigate the relationship between intraluminal appearances of coronary plaques and left coronary bifurcation angle and plaque components using coronary CT virtual intravascular endoscopy (VIE). Fifty patients suspected of coronary artery disease undergoing coronary CT angiography were included in the study. The left bifurcation angle in patients with diseased left...

This experimental study evaluated the possible effects of textual input- based enhancement on the acquisition of passive form on Iranian pre-intermediate EFL learners. Sixty Iranian EFL learners at the pre-intermediate level of proficiency were randomly assigned into three groups; two experimental group and one comparison group. The first experimental group received passages in which the passiv...

Providing a satisfactory visual experience is one of the main goals for present-day electronic multimedia devices. All the enabling technologies for storage, transmission, compression, rendering should preserve, and possibly enhance, the quality of the video signal; to do so, quality control mechanisms are required. These mechanisms rely on systems that can assess the visual quality of the inco...

tūbā et le sens de la nuit  publié en 1987 est un roman de šahrnūs pārsipūr, la romancière contemporaine. ce roman se classe d’emblé, non seulement, parmi les romans d’apprentissage mais aussi, dans la lignée des romans-fleuves. nous ignorons si l’écrivaine a créé cette forme romanesque malgré elle ou si elle en était consciente. dans notre étude, nous essayerons, à l’aide d’une nouvelle lectur...

In this paper, a novel contrast enhancement technique for contrast enhancement of a low-contrast satellite image has been proposed based on the singular value decomposition (SVD) and discrete cosine transform (DCT). The singular value matrix represents the intensity information of the given image and any change on the singular values change the intensity of the input image. The proposed techniq...

Image Enhancement is one of the most important and complex techniques in image processing technology. The main aim of image enhancement is to improve the visual appearance of an image, or to offer a “better transform representation of the image. Various types of images like medical images, satellite images, aerial images and real life photographs suffer from different problems like poor contras...

To test theories of orientation selectivity in primary visual cortex (V1), we have done experiments to measure the dynamics of orientation tuning of single neurons in the V1 cortex of macaque monkeys. Based on our dynamics results, we propose that a V1 cell's orientation selectivity is generated mainly by both tuned enhancement and global suppression. Enhancement near the preferred orientation ...

This study set out to explore whether different input enhancement tasks as implicit instruction techniques had any significant impact on the intake of causative verbs in English as a foreign language among Iranian EFL learners. For this purpose, three intact classes consisting of 75 male and female intermediate L2 learners were randomly divided into three conditions: simultaneous grammar consci...

This study explored the efficacy of visual input enhancement, specifically essay enhancement, for facilitating deaf college students' improvement in English grammatical knowledge. Results documented students' significant improvement immediately after a 10-week instructional intervention, a replication of recent research. Additionally, the results of delayed assessment documented students' signi...
