      An analytical solution for rapidly distorted turbulent shear flow in a rotating frame 

      Akylas, Evaggelos; Kassinos, Stavros C.; Langer, A. C. (2006)
      In this study we apply rapid distortion theory to the case of nonstratified homogeneous turbulence that is sheared in a frame that counter-rotates at a rate that matches in magnitude the rotation associated with the mean ...

      Compression molding of semi-concentrated fiber suspensions: Flow and fiber orientation 

      Ahmed, Alauddin; Alexandrou, Andreas N. (Publ by ASME, 1993)
      The focus of this paper is compression molding of semi-concentrated fiber suspensions. During compression molding a premeasured amount of raw material (charge) is placed between two halves of a die. The die is then closed ...

      The contribution of active and inactive structures to the statistics of a turbulent pipe flow 

      Stylianou, F. S.; Kassinos, Stavros C. (2017)
      The current study is a short follow-up to our most recent work (Stylianou et al., 2016), where among other things we have presented an effective criterion suitable for distinguishing large-scale coherent structures with ...

      Injection molding of dilute and semi-dilute fiber suspensions 

      Alexandrou, Andreas N.; Ahmed, Alauddin (Publ by ASME, 1992)
      The focus of this paper is unsteady flow of semi-dilute fiber suspensions in complex geometries. These flows are typical of injection molding problems in which the raw material in granular form, usually plastic resin mixed ...

      Non-stationary texture segmentation using an AM-FM model 

      Pattichis, Marios S.; Christodoulou, Christodoulos I.; Pattichis, Constantinos S.; Bovik, Alan Conrad (1997)
      We present a novel method for segmenting non-stationary textures. Our approach uses a multidimensional AM-FM representation for the texture, and provides the FM features to an SOFM-LVQ neural network system that performs ...

      A nonoverlapping domain decomposition method for Legendre spectral collocation problems 

      Bialecki, B.; Karageorghis, Andreas (2007)
      We consider the Dirichlet boundary value problem for Poisson's equation in an L-shaped region or a rectangle with a cross-point. In both cases, we approximate the Dirichlet problem using Legendre spectral collocation, that ...

      Nucleon generalized form factors with twisted mass fermions 

      Alexandrou, Constantia; Constantinou, Martha; Drach, V.; Jansen, K.; Kallidonis, Christos; Koutsou, Giannis (Proceedings of Science (PoS), 2013)
      We present results on the nucleon form factors, momentum fraction and helicity moment for Nf = 2 and Nf = 2+1+1 twisted mass fermions for a number of lattice volumes and lattice spacings. First results for a new Nf = 2 ...

      Akylas, Evaggelos; Langer, C. A.; Kassinos, Stavros C.; Demosthenous, E. (2007)
      We apply inviscid rapid distortion theory to the limiting hyperbolic case of turbulent plain strain flow in a rotating frame and investigate the dependence of the evolution of the turbulent kinetic energy on the frame ...

      We calculate the fermion propagator and the quark-antiquark Green's functions for a complete set of ultralocal fermion bilinears, Γ [Γ: scalar (S), pseudoscalar (P), vector (V), axial (A) and tensor (T)], using perturbation ...

      Rapid shear of initially anisotropic turbulence in a rotating frame? 

      Akylas, Evaggelos; Kassinos, Stavros C.; Langer, C. A. (2007)
      In the present study, we investigate, using inviscid rapid distortion theory, the evolution of sheared turbulence in a rotating frame as a function of the rotation rate (including stable, transitional, and unstable regimes), ...

      Representing anisotropy of two-point second-order turbulence velocity correlations using structure tensors 

      Bhattacharya, A.; Kassinos, Stavros C.; Moser, R. D. (2008)
      A locally homogeneous representation for the two-point, second-order turbulent velocity fluctuation Rij(x,r) = 〈u′i(x)u′i(x+r)〉 is formulated in terms of three linearly independent structure tensors [Kassinos et al., J. ...
