  W pracy dokonano analizy 24 linii widmowych atomu i jonu ołowiu, przy użyciu metody diagramów Kinga. Połączenie danych pomiarowych otrzymanych z badań fizyki jądrowej z danymi spektroskopii optycznej pozwoliło na analizę przesunięć izotopowych linii widmowych niezależnie od modelu teoretycznego. W wyniku czego, rozdzielono efekt masy od efektu objętościowego i otrzymano szereg danych spektroskopowych stanowiących bogatą bazę doświadczalną...

  - Year 2009

  Support for modularity allows complex ontologies to be separated into smaller pieces (modules) that are easier to maintain and compute. Instead of considering the entire complex ontology, users may benefit more by starting from a problem-specific set of concepts (signature of problem) from the ontology and exploring its surrounding logical modules. Additionally, an ontology modularization mechanism allows for the splitting up of...
