      Computational predictions of the tensile properties of electrospun fibre meshes: Effect of fibre diameter and fibre orientation 

      Barocas, V. Η; Stylianopoulos, T.; Bashur, C. A.; Goldstein, A. S.; Guelcher, S. A. (2008)
      The mechanical properties of biomaterial scaffolds are crucial for their efficacy in tissue engineering and regenerative medicine. At the microscopic scale, the scaffold must be sufficiently rigid to support cell adhesion, ...

      The Effect of Head Rotation on the Geometry and Hemodynamics of Healthy Vertebral Arteries 

      Aristokleous, Nicolas; Seimenis, Ioannis; Georgiou, Georgios C.; Nicolaïdes, Andrew N.; Anayiotos, Andreas S. (2015)
      The geometric and hemodynamic characteristics of the left and right vertebral arteries (LVA, RVA) of six healthy volunteers were investigated for the supine (S) and the prone position (P) a common sleeping posture with ...

      Effect of posture change on the geometric features of the healthy carotid bifurcation 

      Aristokleous, Nicolas; Seimenis, Ioannis; Papaharilaou, Yannis; Georgiou, Georgios C.; Brott, B. C.; Eracleous, Eleni A.; Anayiotos, Andreas S. (2011)
      Segmented cross-sectional MRI images were used to construct 3-D virtual models of the carotid bifurcation in ten healthy volunteers. Geometric features, such as bifurcation angle, internal carotid artery (ICA) angle, ...

      Estimation of rotational frequency responses 

      Mottershead, J. E.; Kyprianou, Andreas; Ouyang, H. (2003)
      Rotational frequency response functions are potentially valuable for structural damage detection but are difficult to obtain because of the practical problems of applying a pure moment. In the literature various indirect ...

      Impact of head rotation on the individualized common carotid flow and carotid bifurcation hemodynamics 

      Aristokleous, Nicolas; Seimenis, Ioannis; Georgiou, Georgios C.; Papaharilaou, Yannis; Brott, B. C.; Nicolaïdes, Andrew N.; Anayiotos, Andreas S. (2014)
      This paper aims at evaluating the changes that head rotation poses on morphological and flow characteristics of the carotid bifurcation (CB) and on the distribution of parameters that are regarded as important in atherosclerosis ...

      A mechanistic approach in defining inelastic rotation capacity of RC columns 

      Megalooikonomou, K. G.; Pantazopoulou, Stavroula J.; Tastani, S. P. (National Technical University of Athens, 2017)
      When a reinforced concrete (RC) column is subjected to lateral sway as a result of earthquake action, the large strain demand in the end sections is supported by development of strains in the anchorage. This causes the ...

      The method of fundamental solutions for stationary heat conduction problems in rotationally symmetric domains 

      Smyrlis, Yiorgos-Sokratis; Karageorghis, Andreas (2006)
      We propose an efficient boundary collocation method for the solution of certain two- and three-dimensional problems of steady-state heat conduction in Isotropie bimaterials. In particular, in two dimensions we consider the ...

      Rapidly sheared homogeneous stratified turbulence in a rotating frame 

      Kassinos, Stavros C.; Akylas, Evaggelos; Langer, C. A. (2007)
      Rapid distortion theory is applied to stratified homogeneous turbulence that is sheared in a rotating frame. Insight into the stabilizing and destabilizing effects of the combined stratification and frame rotation is gained ...

      A simplified structure-based model using standard turbulence scale equations: computation of rotating wall-bounded flows 

      Kassinos, Stavros C.; Langer, C. A.; Kalitzin, G.; Iaccarino, G. (2006)
      Two linear eddy-viscosity models, the v2-f and k-ω models, have been combined with an algebraic structure-based algorithm for the evaluation of the Reynolds stresses. This closure was originally designed as an integral ...
