Introduction:In this study, a non-invasive method based on consecutive ultrasonic image processing is introduced to assess time rate changes of the carotid artery wall displacement, velocity and acceleration in the longitudinal direction. The application of these parameters to discriminate healthy and atherosclerotic arteries was evaluated. Methods:Longitudinal displacement rate of common ...

Enhancement of the response of reinforced concrete (RC) beams using fiber-reinforced polymer (FRP) reinforcement bars has become a popular structural technique over the past two decades due to the well-known advantages of FRP composites including their high strength-to-weight ratio and excellent corrosion resistance. Thisstudy presents n...

This paper aims to show the application of site-specific response spectra in analysis buildings that are supported by lightly reinforced precast concrete walls. Previous surveys on load-bearing walls multi-storey low-to-moderate seismic regions have found many existing with a connection reinforcement ratio less than wall ratio. When these subjected reversed cyclic loads, lateral is typically co...

This study intends to examine the behavior of a GRS wall with static footing loading above it, while varying positions footing. For such complex structure, finite element modeling is handy and enables look into various stress/strain developed in numerical model. In view above, series (FEM) simulations using software (Optum G2) performed for analysis wall. The governing parameters, as width (B),...

Background: Cerebral aneurysm disease causes intracranial hemorrhage by rupturing, which can eventually, lead to organ failure or death. For this reason, it is important to anticipate the reasons for rupturing of a cerebral aneurysm from biomechanical point of view. Investigating this disease may even help the physicians to find treatments and predict the patient’s situation. This research was ...
