      Numerical and semi-analytical solutions of viscoplastic Poiseuille and Couette flows 

      Chatzimina, Maria K. (Πανεπιστήμιο Κύπρου, Σχολή Θετικών και Εφαρμοσμένων Επιστημών / University of Cyprus, Faculty of Pure and Applied Sciences, 2009-01)
      Η παρούσα διατριβή περιλαμβάνει τις αριθμητικές και ημι-αναλυτικές λύσεις ιξωδοπλαστικών ροών Poiseuille και Couette. Αρχικά επιλύουμε αριθμητικά διάφορες ροές διακοπής ρευστών Bingham χρησιμοποιώντας το ομαλοποιημένο ...

      On comparing several spectral densities 

      Fokianos, Konstantinos; Savvides, A. (2008)
      We investigated the problem of testing equality among spectral densities of several independent stationary processes. Our main methodological contribution is the introduction of a novel semiparametric log-linear model that ...

      On the stability of the simple shear flow of a Johnson-Segalman fluid 

      Georgiou, Georgios C.; Vlassopoulos, Dimitris (1998)
      We solve the time-dependent simple shear flow of a Johnson-Segalman fluid with added Newtonian viscosity. We focus on the case where the steady-state shear stress/shear rate curve is not monotonic. We show that, in addition ...

      Optimum immigration policies based on linear quadratic theory 

      Tzortzis, I.; Charalambous, Charalambos D. (2010)
      In this paper, it is demonstrated that the Theory of Linear Quadratic is applicable in deriving optimum immigration policies, while maintaining population and immigration levels close to certain pre-specified reference ...

      Planar investigation of the seismic response of ancient columns and colonnades with epistyles using a custom-made software 

      Papaloizou, Loizos; Komodromos, Petros I. (2009)
      Abstract: In this paper, the dynamic behavior of multi-drum columns and colonnades with epistyles under earthquake excitations is examined through planar numerical simulations. A specialized software application, developed ...

      Some aspects of the one-dimensional version of the method of fundamental solutions 

      Smyrlis, Yiorgos-Sokratis; Karageorghis, Andreas; Georgiou, Georgios C. (2001)
      The method of fundamental solutions (MFS) is a well-established boundary-type numerical method for the solution of certain two- and three-dimensional elliptic boundary value problems. The basic ideas were introduced by ...

      Study of an adaptive fuzzy controller based on the adaptation of relative rule weights 

      Sekercioglu, Y. Ahmet; Pitsillides, Andreas; Egan, Gregory K. (1994)
      An adaptive fuzzy controller models the qualitative control actions of a human operator. It is applicable to systems for which explicit mathematical models are not easily obtainable. Qualitative control actions are modeled ...

      Target cascading in vehicle redesign: A class VI truck study 

      Kim, H. M.; Kokkolaras, M.; Louca, Loucas S.; Delagrammatikas, G. J.; Michelena, N. F.; Filipi, Z. S.; Papalambros, P. Y.; Stein, J. L.; Assanis, D. N. (2002)
      The analytical target cascading process is applied to the redesign of a U.S. class VI truck. Necessary simulation and analysis models for predicting vehicle dynamics, powertrain, and suspension behaviour are developed. ...

      The Toda lattice is super-integrable 

      Agrotis, Maria A.; Damianou, Pantelis A.; Sophocleous, Christodoulos (2006)
      We prove that the classical, non-periodic Toda lattice is super-integrable. In other words, we show that it possesses 2 N - 1 independent constants of motion, where N is the number of degrees of freedom. The main ingredient ...
