New methods of degradations on the pavement’s surface, such as top-down cracking and delamination, caused by repeated passage heavy vehicles led to questions about impact contact between tire pavement. In fact, increase service life structures, future road design must have a precise knowledge consequences parameters state stress deformation in this paper, tractive rolling under effect friction ...

AIMS Early left ventricular (LV) dysfunction in asymptomatic patients with severe aortic regurgitation (AR) may go undetected due to the lack of a sufficiently sensitive diagnostic tool. Ultrasonic strain/strain rate (S/SR) imaging should now provide such sensitivity in detecting early dysfunction in regional LV systolic deformation. The aim of this study was to understand and define the change...

conclusions echocardiography and 2d speckle tracking strain imaging shows improvements in left ventricular deformation indices in atrioventricular reentrant tachycardia (avrt) and atrioventricular nodal reentrant tachycardia (avnrt) patients for the mean systolic strain and strain rate at 24 hours and the three-month follow-up. in spite of the normal lvef, even during sinus rhythm, deformation ...

During the last few decades, the continued growth and expansion of stress echocardiography in daily clinical practice has led to the search and development of new and more quantitative technologies in an attempt to reduce the subjectivity of wall motion analysis by conventional visual method. (1) The evaluation of coronary flow reserve by Doppler echocardiography and myocardial deformation para...

Atrophy of the brain due to the death of neurons in Alzheimer’s Disease (AD) is well observed in longitudinal structural magnetic resonance images (MRIs). This thesis focuses on developing a biophysical model able to reproduce changes observed in the longitudinal MRIs of AD patients. Simulating realistic longitudinal MRIs with atrophy from such a model could be used to evaluate brain morphometr...

Roll forming process is used for manufacturing sheet metal parts by successive bending and creating the final shape with gradual deformation. In this article, deformation of a pre-punched sheet due to the roll forming process was studied. Two main defects in the roll forming process are ovality of holes and bow defect. The ovality of the hole is influenced by the process parameters including sh...

Using language of dg PROPs we give a new short proof of existence of star products on (formal) germs of Poisson manifolds.

BACKGROUND Assessment of left (LV) ventricular function is one of the most important tasks of cardiovascular magnetic resonance (CMR). Impairment of LV deformation is a strong predictor of cardiovascular outcome in various cardiac diseases like ischemic heart disease or cardiomyopathies. The aim of the study was to provide reference values for myocardial deformation derived from the CMR feature...
