• Spam classification methods besed on users e-mail communication graphs

  Publication

  • H. Krawczyk
  • R. Brendel

  - Year 2006

  W artykule poddano analizie grafy zbudowane w oparciu o logi serwerów pocztowych. Węzły grafów reprezentują nadawców i odbiorców wiadomości e-mail natomiast krawędzie przedstawiają procesy wymiany wiadomości e-mail. Analiza grafów pozwala na znalezienie korelacji pomiędzy topologią grafów a relacjami pomiędzy użytkownikami serwisu pocztowego. W oparciu o te relacje zaproponowano algorytm klasyfikujący wymieniane wiadomości e-mail...

  - PHYSICAL REVIEW LETTERS - Year 2014

  In this Letter we give a set of necessary and sufficient conditions such that quantum players of a two-party xor game cannot perform any better than classical players. With any such game, we associate a graph and examine its zero-error communication capacity. This allows us to specify a broad new class of graphs for which the Shannon capacity can be calculated. The conditions also enable the parametrization of new families of games...

• The cohomological span of LS-Conley index

  Publication

  • J. Maksymiuk

  - JOURNAL OF DIFFERENTIAL EQUATIONS - Year 2015

  In this paper we introduce a new homotopy invariant – the cohomological span of LS-Conley index. We prove the theorems on the existence of critical points for a class of strongly indefinite functionals with the gradient of the form Lx+K(x), where L is bounded linear and K is completely continuous. We give examples of Hamiltonian systems for which our methods give better results than the Morse inequalities. We also give a formula...

• On the hardness of computing span of subcubic graphs

  Publication

  • R. Janczewski

  - INFORMATION PROCESSING LETTERS - Year 2016

  In the paper we study the problem of finding ξ-colorings with minimal span, i.e. the difference between the largest and the smallest color used.

• Test loading of the longest span arch bridge in Poland

  Publication

  • M. Malinowski
  • M. Miśkiewicz

  - Year 2009

  Bridge structures undergo thorough examination during test loading before they come into use. The aim of the examination is to check the correctness of the working structure and construction design assumptions. Test loading on the bridge is preceded by examination specification. This paper describes computational model and test loading results carried out during examibation of the bridge over the Vistula within the bypass of Puławy...
