Quaternary adder, subtractor and multiplier using quaternary multiplexer
International Journal of Electronics, 1987Multiplexers, as in the case of binary, are very useful building blocks in the development of quaternary systems. The use of quaternary multiplexer (QMUX) in the implementation of quaternary adder, subtractor and multiplier is described in this paper. Quaternary coded decimal (QCD) adder/subtractor and quaternary excess-3 adder/subtractor realization ...

, 2019 More than 100 years of continuing research into the Quaternary of Egypt has produced numerous publications. In the last twenty years, Quaternary studies have witnessed great advances in both theories and methodologies, and the pace of archaeological research has accelerated as a new generation of researchers joined in expounding the different ...

Abstract We review the historical purposes and procedures for stratigraphical division and naming within the Quaternary, and summarize the current requirements for formal partitioning through the International Commission on Stratigraphy (ICS). A raft of new data and evidence has impacted traditional approaches: quasi-continuous records from ocean ...

Abstract Minnesota was affected by Laurentide ice lobes of different provenance. Lake Agassiz drained through Minnesota. Tills in Minnesota are correlated on the basis of their lithologic and mineralogic composition. A number of dating methods along with weathering horizons and truncated paleosols have been used to strengthen correlations in pre-MIS ...
