Aligning CNF- and Equivalence-Reasoning [chapter]

Marijn Heule, Hans van Maaren
2005 Lecture Notes in Computer Science  
Large instances of such CNF formulas cannot be solved in reasonable time if no detection of, and extra reasoning with, these clauses is incorporated.  ...  That is, in solving these formulas, there is a more or less separate algorithmic device dealing with the equivalence clauses, called equivalence reasoning, and another dealing with the remaining clauses  ...  We conclude that aligning Equivalence-and CNF-reasoning as carried out pays off convincingly.  ...

SEMilarity: Towards a Model-Driven Approach to Similarity

Rudi Araújo, Helena Sofia Pinto
2007 International Workshop on Description Logics  
These methods rely on similarity measures that are mainly focused on terminological, structural and extensional properties of the ontologies.  ...  Ontology matching and alignment is an area that deals with this problem by establishing relations (usually equivalence and subsumption relations) between elements in different ontologies.  ...  We observed that relsat performed considerably faster using the following equivalent equation: σ(T 1 , T 2 ) = (2 |C| − mc(cnf(C 1 ))) − mc(cnf(C 2 )) + 2 × mc(cnf(C 1 C 2 )) /2 |C| .  ...

2018 arXiv   pre-print
Furthermore, the experimental setup can be used to quickly characterize the dynamic properties of flowing CNF and thus aid in determining the quality of the dispersion and its usability in material processes  ...  The performance of these new cellulose materials depends on how easily CNF alignment can be controlled with hydrodynamic forces, which are always in competition with a different process driving the system  ...  Acknowledgments The authors acknowledge financial support from Wallenberg Wood Science Center (WWSC) and the Alf de Ruvo Memorial Foundation.

Jatin Sethi, Kristiina Oksman, Mirja Illikainen, Juho Antti Sirviö
2018 Carbohydrate Polymers  
This has been a bottleneck, 15 which is restricting the commercialization of CNF derived products such as nanopapers and CNF 16 reinforced paper sheets.  ...  As a remedy, we suggest an eco-friendly water-based approach that 17 involves the use of sonication energy and lactic acid (LA) to modify the surface of CNFs.  ...  The tensile strength of LA modified CNF nanopaper and reference 324 were equivalent, but that of CNF(0.1M)NaCl drained one was 22% less than both.  ...
