During wire electrical discharge machining (WEDM), rupture may deteriorate workpieces’ machined surfaces and increase the processing time. However, only a few referenced papers focused on during past decades because of its complexity. In this research, machine learning (ML) technique was applied to analyze relationship between manufacturing parameters chance rupture. Three parameters, including...

background: uterine rupture at the site of a previous cesarean scar is an uncommon but catastrophic complication of pregnancy, which is associated with significant maternal and fetal morbidity and mortality. case presentation: a 30-year old woman at 24th week of gestation and complaint of pain, contractions and spotting was admitted in royan institute in tehran, iran. she had a past medical his...

Carotid atherosclerotic plaques are a major cause of ischaemic stroke. The biomechanical environment to which the arterial wall and plaque is subjected to plays an important role in the initiation, progression and rupture of carotid plaques. MRI is frequently used to characterize the morphology of a carotid plaque, but new developments in MRI enable more functional assessment of carotid plaques...

Background: With an aim to reduce the rates of repeat cesarean section in women with a previous scar, prediction of scar rupture or dehiscence is important. If we could predict the risk of rupture by measuring the scar thickness closer to term, we could pursue a trial of scar safely. Aims: To evaluate the use of ultrasound measured thickness of lower uterine segment as one of the predictors of ...

iran is a major world producer of walnuts and a hub of walnut exports to other countries. walnut harvesting and cracking is still done manually, which increases price and waste. design and development of an effective harvester and walnut crusher is required to reduce costs and wastage. this study determined the mechanical properties of a test apparatus employing two flat jaws using different tr...
