      Learning from the current status of agile adoption 

      Kapitsaki, Georgia M.; Christou, Marios Andreas (2015)
      Software processes have evolved significantly since the first formal appearance of software engineering. The academia and the industry have introduced, embraced or rejected various methodologies that are more or less ...

      Numerical investigation of the nonlinear heat diffusion equation with high nonlinearity on the boundary 

      Christou, Marios Andreas; Sophocleous, Christodoulos; Christov, Christo I. (2008)
      A nonlinear heat diffusion problem is considered when the thermal conductivity and heat capacity are nonlinear functions of the temperature. At one of the boundaries a highly nonlinear condition is imposed involving both ...

      Numerical similarity reductions of the (1+3)-dimensional Burgers equation 

      Christou, Marios Andreas; Sophocleous, Christodoulos (2011)
      We consider the (1+3)-dimensional Burgers equation ut = u xx + uyy + uzz + uux which has considerable interest in mathematical physics. Lie symmetries are used to reduce it to certain ordinary differential equations. We ...

      Numerical solutions of boundary value problems for variable coefficient generalized KdV equations using Lie symmetries 

      Vaneeva, Olena O.; Papanicolaou, N. C.; Christou, Marios Andreas; Sophocleous, Christodoulos (2014)
      The exhaustive group classification of a class of variable coefficient generalized KdV equations is presented, which completes and enhances results existing in the literature. Lie symmetries are used for solving an initial ...

      On the classification of similarity solutions of a two-dimensional diffusion-advection equation 

      Demetriou, Ellie; Christou, Marios Andreas; Sophocleous, Christodoulos (2007)
      We consider the two-dimensional diffusion-advection equation ut = Duyy - frac(d k, d u) ux. We present the classification of Lie symmetries of this equation. For the case k(u) = u2 we give the complete list of similarity ...

      Similarity reductions of the (1 + 3)-dimensional Burgers equation 

      Christou, Marios Andreas; Ivanova, Nataliya M.; Sophocleous, Christodoulos (2009)
      We consider the (1 + 3)-dimensional Burgers equation ut = uxx + uyy + uzz + uux which has considerable interest in mathematical physics. We complete the list of similarity reductions that are obtained from the Lie symmetries ...

      Where is Scrum in the current Agile world? 

      Kapitsaki, Georgia M.; Christou, Marios Andreas (SciTePress, 2014)
      A variety of methodologies in software processes exist nowadays with the Agile software development having gained significant ground since the introduction of the Agile manifesto in 2001. Scrum is a representative Agile ...
