A statistical approach to determine the neighborhood function and learning rate in Self-Organizing Maps
(Springer-Verlag Singapore Pte LTD, 1998)
The problem of choosing the neighborhood function and learning rate in Kohonen's Self-Organizing Map (SOM) is generally application dependent, empirical and difficult to analyze. In this paper, a new approach based on the ...
Lichens of the Akşehir District (Konya)
(1998)
Eighty-nine lichen species belonging to 33 genera from Akşehir District of Kenya were determined. Staurothele frustulenta Vainio is a new record for the lichen flora of Turkey.
5-acetylindan aryloxyacetohydrazone derivatives: Synthesis and antituberculosis activity
(1998)
Some 5-acetylindan aryloxyacetohydrazone derivatives were synthesized by reacting 5-acetylindan with aryloxyacetohidrazide derivatives in butanol. The structure of the compounds obtained were performed by using IR, 1H NMR, ...
New approach for determining the coefficient of consolidation, Cv, for normally consolidated kaolinite clay
(International Society Offshore& Polar Engineers, 1998)
in this study, the coefficient of consolidation of kaolinite clay is determined using a newly developed test system. The results of these experiments are compared with results obtained from the conventional oedometer test ...
Synthesis and characterization of some 2-(substituted arylacylthio)thiazolene derivatives
(1998)
In this study, five new 2-(substituted arylacyl-thio) thiazoline derivatives were synthesized by reacting 2-thiazoline-2-thiol with arlacylhalides. The structures of the compounds obtained were elucidated by IR, 1H-NMR, ...
