a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
We read with interest the article by Duszańska et al. [1] entitled ‘Predictors of successful iatrogenic pseudoaneurysm compression dressing repair’ recently published in the journal. The authors suggested that compression dressing repair (CPR) might serve as an alternative method of femoral pseudoaneurysm (FPA) management in patients with low forward and reverse velocities of the flow in pseudo...
introduction: the cholinergic system plays an important role in learning and memory. administration of either extracts of crocus sativus (saffron) or its constituent, crocin, reduced ethanol-induced memory impairment. based on the above findings, we investigated the effect of crocin in antagonizing spatial learning and memory impairment induced by scopolamine, a cholinergic receptor antagonist,...
When somebody asks me, what I do in science, I call myself a specialist in mathematical physics. As I have been there for more than 40 years, I have some definite interpretation of this combination of words: " mathematical physics. " Cynics or purists can insist that this is neither mathematics nor physics, adding comments with a different degree of malice. Naturally, this calls for an answer, ...
OBJECTIVE Notwithstanding its widely perceived advantages, laparoscopic appendectomy has not yet met with universal acceptance. The aim of the present work is to illustrate retrospectively the results of a case-control experience with laparoscopic versus open appendectomy carried out at our institution. METHODS Between January 1993 and November 2000, 555 patients (M:F = 210:345; mean age 25.2...
istorical Aspect In 1827 Robert Adams was probably the first person to recognize Atrial Fibrillation (AF) clinically as a sign of mitral stenosis. Hope in 1839 identified irregular pulse in association with mitral stenosis. Etienne Marcy in 1863 published a tracing of atrial fibrillation from a patient with mitral stenosis. Arthur Cushney described it in 1899. Initially AF was termed as Deleriu...
