The design variables included wall thickness, lengths of sections, and taper angle.
Both experimental tests and finite element modelling are employed to determine the influences of pertinent geometry parameters of hollow tube and foam filler, including wall thickness, and structure length on the compressive behaviour of the compound tubes.
The structural and electrical properties studied include wall thickness, binding energy, curvature energy, band gap, work function, charge transfer etc. Curvature energy calculations show that the all the nanotubes follow classical elasticity theory.
Such analysis is further complicated by the need of a precise description of the three-dimensional geometry of the aneurysm (including wall thickness) and boundary conditions.
The associated design variables include the wall thickness and length of each segment composing the column.
Suspicious features include increased wall thickness (>3 mm), increased signal intensity on T2-weighted images (Fig. 11b) and progressive enhancement of the bile ducts (due to the fibrotic component of the tumour) following intravenous administration of gadolinium.
With physiological aging, the LV undergoes monotonic structural changes that include increased wall thickness, chamber diameter, and mass [ 6- 8].
Furthermore, the optical properties of gold nanocages can be tailored by modulating the nanostructure geometric parameters including size, wall thickness and wall porosity.
Variables measured on M-mode echocardiography including LV wall thickness, LV chamber dimensions, and systolic and diastolic function were analyzed as described previously [ 24].
Progressive RV remodeling, including increased wall thickness and myocardial hypertrophy as well as interstitial fibrosis, represents the main characteristics of pulmonary arterial hypertension (PAH) besides the pulmonary vascular remodeling and vasoconstriction processes in the lungs of affected patients [ 18].
