Discovering Concepts Using Spreadsheet Tables

Existing work on knowledge discovery mostly uses natural language techniques to extract entities and relationships from textual documents. However, today relational tables are abundant in quantities, and o‰en contain clean and well-structured data values. So far these rich relational tables have been largely overlooked for the purpose of knowledge discovery. In this work, we study the problem o...

Fourier Analysis Using A Spreadsheet

F or many tasks involving Fourier analysis, a spreadsheet is an excellent tool. Using examples, this article shows that for data sets involving perhaps a hundred points and a few tens of coefficients, a spreadshe& method is practical and quick on perwnal computers such as the Macintosh SE or the IBM PC AT and compatibles. With enhanced hardware such as floating-point co-pmcaasor chips, the numb...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Practical First-order Reliability Computations Using Spreadsheet

ABSRACT: A practical procedure for reliability analysis involving correlated nonnormals was described in Low & Tang (1997), using object-oriented constrained optimization in the ubiquitous spreadsheet platform. Numerical derivatives and iterative search for the design point were automatic. The objective of this paper is to further illustrate the 1997 procedure for two geotechnical problems with...
