  • Finite element simulations of window Josephson junctions 

    Vavalis, M.; Mu, M.; Sarailidis, G. (2012)
    This paper deals with the numerical simulation of the steady state two dimensional window Josephson junctions by finite element method. The model is represented by a sine-Gordon type composite PDE problem. Convergence and ...
  • Front-paging online newspapers 

    Koutsaftikis, I.; Nanas, N.; Vavalis, M. (2013)
    Online newspapers and magazines still find it difficult to let readers discover and just read news. A plethora of stories on the front (home) page, overuse of complex grids, vast navigation lists and advertising immaturity ...
  • Immune inspired information filtering in a high dimensional space 

    Nanas, N.; Kodovas, S.; Vavalis, M.; Houstis, E. (2010)
    Adaptive Information Filtering is a challenging computational problem that requires a high dimensional feature space. However, theoretical issues arise when vector-based representations are adopted in such a space. In this ...
  • Immune learning in a dynamic information environment 

    Nanas, N.; Vavalis, M.; Kellis, L. (2009)
    In Adaptive Information Filtering, the user profile has to be able to define and maintain an accurate representation of the user's interests over time. According to Autopoietic Theory, the immune system faces a similar ...
  • A knowledge management architecture for 3D shapes and applications 

    Pitikakis, M.; Houstis, C.; Vasilakis, G.; Vavalis, M. (2005)
    In this paper, we present a knowledge-based approach to 3D shape management and service composition, exploiting and extending Web Services and Semantic Web technologies. Semantic Web technology fosters semantic interoperability, ...
  • Large scale simulations for electric energy markets 

    Fainti, R.; Nasiakou, A.; Tsoukalas, E.; Vavalis, M. (2014)
    The aim of this paper is to present the design, an early proof-of-concept implementation and the preliminary experimentation of a simulation platform focused on holistic detailed studies of electric energy markets. The ...
  • Personalised news and scientific literature aggregation 

    Nanas, N.; Vavalis, M.; Houstis, E. (2010)
    Content-based filtering can be deployed for personalised information dissemination on the web, but this is a possibility that has been largely ignored. Nowadays, there are no successful content-based filtering applications ...
  • Providing support for integrated scientific computing: Metacomputing meets the grid and the semantic web 

    Lalis, S.; Houstis, C.; Pitikakis, M.; Vasilakis, G.; Vavalis, M. (2005)
    In this paper, we present an integrated system architecture for metacomputing on top of distributed scientific resources via semantic-driven information management. Our approach is to consider both data and programs as ...
  • Revisiting evolutionary information filtering 

    Nanas, N.; Kodovas, S.; Vavalis, M. (2010)
    Adaptive Information Filtering seeks a solution to the problem of information overload through a tailored representation of the user's interests, called user profile, which constantly adapts to changes in them. Evolutionary ...
  • Semantic based search engine for 3D shapes: Design and early prototype implementation 

    Vasilakis, G.; Pitikakis, M.; Vavalis, M.; Houstis, C. (2005)
    Searching for 3D resources is gradually becoming one of those intriguing research topics that have the potential to shape how users will access and interact with the internet in the years to come. Search engines like Google ...
  • Semantically interoperable three-dimensional scientific objects 

    Pitikakis, M.; Vavalis, M.; Houstis, C. (2012)
    In recent years, digital content of three-dimensional (3D) scientific objects has become widespread and is made available in a plethora of on-line scientific repositories. A systematic and formal approach becomes necessary ...
