Digital image correlation was used to measure the full-field deformation of paperboard and handsheet tensile specimens. The correlation technique was able to accurately measure strain in regions 0.6 by 0.6 mm. Results showed the variation of strain to be much larger than has been previously reported. For machinemade paperboard tested in the cross-direction, the variation of strain increased thr...

PURPOSE To determine the feasibility of using magnetic resonance imaging (MRI) to non-invasively measure strain in the aortic wall. MATERIALS AND METHODS Cine phase contrast MRI was used to measure the velocity of the aortic wall and calculate changes in circumferential strain over the cardiac cycle. A deformable vessel phantom was used for initial testing and in vitro validation. Ultrasonic ...

For financial investment with a pre-specified investment target, the risk can be regarded as the uncertainty of the earliest target reaching time. As a refinement of this new perspective of risk measure, we introduce a new risk measure which is the extra time cost between the current time and the earliest time that the investment achieves the target or beats the benchmark at some confidence lev...

This research work presents the study on fracture behavior of Al6061 with graphite particulate composite produced by the stir casting technique. The materials selected for the proposed work is Al6061 and graphite particles. Compact tension (CT) specimens were utilized to determine fracture toughness for different thickness of composite. In the present work, optimizing the parameters of the comp...

AIMS Left ventricular ejection fraction (EF) is a suboptimal measure of ventricular function. Recent mathematical modelling of left ventricular contraction has shown that the EF is determined by both myocardial shortening (strain) and by end-diastolic wall thickness. Increasing end-diastolic wall thickness resulted in augmented radial wall thickening. This may result in a significant 'overestim...

background: happiness as one of the main positive health indicators has drawn more attention in recent years among policy makers and health system managers. there are few studies performed to measure happiness in population-based settings in iran. in response to this need, our study tends to assess iranians subjective happiness in tehran, capital city of iran. m aterials and methods: present st...

Abstract Especially in the insurance industry interest rate models play a crucial role, e.g. to calculate company’s liabilities, performance scenarios or risk measures. A prominant candidate is 2-Additive-Factor Gaussian Model (Gauss2++ model) —in different representation also known as 2-Factor Hull-White model . In this paper, we propose framework estimate such that it can be applied under neu...

BACKGROUND While most Direct laryngoscopy leads to dental injury in 25-39% of cases. Dental injury occurs when the forces and impacts applied to the teeth exceed the ability of the structures to dissipate energy and stress. The purpose of this study was to measure strain, (which is the change produced in the length of the tooth by a force applied to the tooth) strain rate, and strain-time integ...
