    • Efficient distributed load balancing for parallel algorithms 

      Cosenza, Biagio (Universita degli studi di Salerno, 2011-04-29)
      With the advent of massive parallel processing technology, exploiting the power offered by hundreds, or even thousands of processors is all but a trivial task. Computing by using multi-processor, multi-core or many-core ...

    • Flavor mixing in quantum field theory and quantum information 

      Di Mauro, Marco (Universita degli studi di Salerno, 2011-05-10)
      After reviewing the formalism for describing flavor mixing, both in Quantum Mechanics and Quantum Field Theory, some consequences along three different directions are studied. First, it is proposed that flavor mixing can ...

    • Imbedding and compactness results in some function spaces 

      D'Ambrosio, Roberta (Universita degli studi di Salerno, 2011-03-16)
      Nello studio di vari problemi ellittici con soluzioni in spazi di Sobolev S( ) (con o senza peso) definiti su un aperto di Rn, non necessariamente limitato o regolare, spesso risulta necessario stabilire risultati di ...

    • Le potenzialità dell’e-learning nell’apprendimento della matematica 

      Maresca, Giuseppe (Universita degli studi di Salerno, 2011-02-18)
      La tesi indaga e discute le potenzialità dell’e-learning nell’apprendimento della matematica. Oggi la tecnologia dell’informazione e della comunicazione non è più strettamente legata a qualche quadro teorico. In passato ...

    • Multi-biclustering solutions for classification and prediction problems 

      Nosova, Ekaterina (2011-03-19)
      The search for similarities in large data sets has a relevant role in many scientific fields. It permits to classify several types of data without an explicit information about them. Unfortunately, the experimental ...

    • On the verification of parametric and real-time systems 

      Di Giampaolo, Barbara (Universita degli studi di Salerno, 2011-05-06)
      Parametric and Real-Time Systems play a central role in the theory underlying the Verification and Synthesis problems. Real-time systems are present everywhere and are used in safety critical applications, such as flight ...
