Clinical assessment of arterial stiffness [PDF]
, 2010 Increased arterial stiffness is associated with ageing, cardiovascular disease diabetes and renal failure. The aims of this thesis were to investigate the reproducibility of a tissue Doppler imaging (TDI) based ultrasound system to calculate indices of ...

Pulse, 2013 Stiffness of large arteries has been long recognized as a significant determinant of pulse pressure. However, it is only in recent decades, with the accumulation of longitudinal data from large and varied epidemiological studies of morbidity and mortality associated with cardiovascular disease, that it has emerged as an independent predictor of ...

Immersion and Invariance Control for an Antagonistic Joint with Nonlinear Mechanical Stiffness [PDF]
, 2010 Tendon controlled robots with nonlinear mechanical tendon stiffness are becoming more and more popular. With the appropriate actuation, the joint position and the stiffness between motor and link side can be prescribed at the same time. In this paper,

Assessing the Role of Longitudinal Variability of Vertical Track Stiffness in the Long-Term Deterioration [PDF]
, 2016 The performance of the railway system in terms of dynamic loading is depending mainly on the track support conditions. Usually, the track stiffness is used as the main parameter to describe the support conditions and is defined as the ratio of the load ...

Stability of fixed-fixed shallow arches under arbitrary radial and vertical forces [PDF]
Инженерно-строительный журнал, 2020 In the present paper the planar stability of fixed-fixed shallow circular arches is investigated. The arches are made of linearly elastic, functionally graded material and are subject to a concentrated radial or vertical dead force at an arbitrary ...
