On the Usability of Probably Approximately Correct Implication Bases
We revisit the notion of probably approximately correct implication bases
from the literature and present a first formulation in the language of formal
concept analysis, with the goal to investigate whether such bases represent a
suitable substitute for exact implication bases in practical use-cases. To this
end, we quantitatively examine the behavior of probably approximately correct
implication bases on artificial and real-world data sets and compare their
precision and recall with respect to their corresponding exact implication
bases. Using a small example, we also provide qualitative insight that
implications from probably approximately correct bases can still represent
meaningful knowledge from a given data set.Comment: 17 pages, 8 figures; typos added, corrected x-label on graph
Interaction between sodium chloride and texture in semi-hard Danish cheese as affected by brining time, dl -starter culture, chymosin type and cheese ripening
Reduced NaCl in semi-hard cheeses greatly affects textural and sensory properties. The interaction between cheese NaCl concentration and texture was affected by brining time (0â28 h), dl-starter cultures (C1, C2, and C3), chymosin type (bovine or camel), and ripening time (1â12 weeks). Cheese NaCl levels ranged from <0.15 to 1.90% (w/w). NaCl distribution changed during ripening; migration from cheese edge to core led to a more homogeneous NaCl distribution after 12 weeks. As ripening time increased, cheese firmness decreased. Cheeses with reduced NaCl were less firm and more compressible. Cheeses produced with C2 were significantly firmer than those produced with C1; cheeses produced with C3 had higher firmness and compressibility. In NaCl reduced cheese, use of camel chymosin as coagulant resulted in significantly higher firmness than that given using bovine chymosin. Overall, cheese NaCl content is reducible without significant textural impact using well-defined starter cultures and camel chymosin
Investigation of the Suppression of the Narrow Channel Effect in Deep Sub-Micron EXTIGATE Transistors
A suppression of the narrow channel effect for deep sub-micron CMOS transistors when using a novel device architecture called EXTIGATE has recently been shown. This work compares the narrow channel effect in the EXTIGATE and in conventional shallow trench isolated MOS transistors by means of three-dimensional coupled process and device simulation. The 3D simulation analysis shows that the bird's beak shaped thickening of the gate oxide and the sharply terminated gate electrode at the edge of the active area which are typical for the EXTIGATE technology play an important role in the suppression of the narrow channel effect
