  • Testing and Comparing the Performance of Cloud Service Providers using a Service Broker Architecture 

    Elango DM; Fowley F; Pahl C (Springer, 2018)
    Service brokers are tools that allow different individual service providers to be integrated. An API can be a mechanism to provide a joint interface. Broker can actually also be use for more than integration. We use a ...
  • There Is No Rose Without A Thorn: An Assessment of a Game Design Experience for Children 

    Dodero, G; Gennari, R; Melonio, A; Torello, S (ACM, 2015)
    Game design is recently conducted at school for eliciting children's design ideas about games for them. However, game design is a complex interaction design task, requiring rather mature cognitive skills. This paper reflects ...
  • Tools for supporting hybrid learning strategies in Open Source software environments 

    Forcheri, P; Dodero, G; Succi, G; Di Cerbo, F (Springer, 2008)
    In this paper, we illustrate how a cooperative learning paradigm may benefit from cutting edge e-learning techniques. We use Web 2.0 resources (especially AJAX) to fulfill requirements for an interactive-constructivistic ...
  • Towards distributed configuration 

    Felfernig A; Friedrich GE; Jannach D; Zanker M (Springer, 2001)
    Shorter product cycles, lower prices, and the production of highly variant products tailored to the customer needs are the main reasons for the proceeding success of product configuration systems. However, today’s product ...
  • Variable block algebraic recursive multilevel solver (VBARMS) for sparse linear systems 

    Carpentieri B; Liao J; Sosonkina M (Bader M [and others], 2014)
    We present and discuss the parallel implementation of a multi-elimination incomplete LU factorization method for solving sparse linear systems. The proposed solver exploits any available block structure during the ...
