A novel method to evaluate cleaning quality of oil in shale using pyrolysis pyrogram
Energy Science & Engineering, 2020 Complete and thorough core cleaning is a critical prerequisite for the precise measurements of most rock's petrophysical parameters. In shale, the oil cleaning process, aimed to remove the volatile hydrocarbons, is often complicated by the requirement ...

The effect of data cleaning on record linkage quality [PDF]
BMC Medical Informatics and Decision Making, 2013 Within the field of record linkage, numerous data cleaning and standardisation techniques are employed to ensure the highest quality of links. While these facilities are common in record linkage software packages and are regularly deployed across record linkage units, little work has been published demonstrating the impact of data cleaning on linkage ...
