Lineage

This URL provides the access to the most recent output from the database. The output is being overwritten as often as possible.

This data set was output from J-CORES database by using its complete Bulk Export function Version 1.9.9 from 2019-09-11T04:29:30Z till 2019-09-11T04:30:03Z. The specification of the outputs is available to be referred. Bulk Export gives a file bulk.csv with various attachment files (e.g. image files). Files bulk-something.csv are generated by picking some kinds of data from bulk.csv. Files something.zip consist of bulk-something.csv and related attachment files. Files bulk-something.csv are in character encoding UTF-8 with line ending characters CRLF. The database has a flexibility to store numerical/text values and attached files for user-defined parameters, which are output into User-Defined Parameter column group in bulk.csv.

According to a vendor's comment, "LET should at least reach values of 50 (even with difficult samples like sediments), better more than 100. If LET values are not higher than 4 when measuring sediments, this means that the contact between probe and sample is insufficient." If the highest LET value of the iterative measurements is 4 and over, the data is evaluated as "Qualified" and low quality measurement results (LET <4) are excluded from the average of thermal conductivity. In case the highest LET value of the iterative measurements is lower than 4, the data is evaluated as "Unqualified" and the average of all measurements is given as the thermal conductivity.
