    • A TOOL BASED ON DL FOR UML MODEL CONSISTENCY CHECKING 
      Simmonds Wagemann, Jocelyn Paola; Bastarrica Piñeyro, María Cecilia; Hitschfeld Kahler, Nancy; Rivas, Sebastían (WORLD SCIENTIFIC PUBL CO PTE LTD, 2008-09)
      Automated consistency checking of UML models becomes necessary as models grow in size and complexity. Since the UML metamodel does not enforce model consistency, there are no fixed guidelines on how to approach the ...
    • Tools for improving feeding strategies in a SBR with several species 
      Gajardo, Pedro; Ramírez Cabrera, Héctor; Rodríguez, Julio C. (Springer, 2014)
      This paper analyzes feeding strategies in a sequential batch reactor (SBR) with the objective of reaching a given (low) substrate level as quickly as possible for a given volume of water. Inside the SBR, several species ...

      Mobile robots are no longer used exclusively in research laboratories and indoor controlled environments, but are now also used in dynamic industrial environments, including outdoor sites. Mining is one industry where ...
    • Topological spin waves in the atomic-scale magnetic skyrmion crystal 
      Roldán Molina, A.; Núñez Vásquez, Álvaro; Fernández Rossier, J. (IOP, 2016)
      We study the spin waves of the triangular skyrmion crystal that emerges in a two-dimensional spin lattice model as a result of the competition between Heisenberg exchange, Dzyalonshinkii-Moriya interactions, Zeeman coupling ...
    • Topological states of non-Hermitian systems 
      Martinez Alvarez, V.; Barrios-Vargas, J.; Berdakin, M.; Foa Torres, L. (Springer Verlag, 2018)
      Recently, the search for topological states of matter has turned to non-Hermitian systems, which exhibit a rich variety of unique properties without Hermitian counterparts. Lattices modeled through non-Hermitian Hamiltonians ...
    • Topological transitions in an oscillatory driven liquid crystal cell 
      Clerc Gavilán, Marcel; Kowalczyk, Michal; Zambra, Valeska (Nature, 2020)
      Matter under different equilibrium conditions of pressure and temperature exhibits different states such as solid, liquid, gas, and plasma. Exotic states of matter, such as Bose-Einstein condensates, superfluidity, chiral ...
