In this study, the author investigated the relationship between the layout of objects placed on a table and tidying up. The author developed a system that can tidy up through cooperation between a robot and human. For realizing this system, it was necessary to investigate the types of instances in which people think a table top is disorderly. The author conducted an experiment in which particip...

Mass spectrometry (MS) is a powerful tool for measuring biomolecules, but the data produced often difficult to handle computationally because it stored as ragged array. In R, this format typically encoded in complex S4 objects built around environments, requiring an extensive background R perform even simple tasks. However, adoption of tidy [@wickham2014] provides alternate structure that highl...

Noting that the usual ‘propositionally’ based way of composing retrenchments can yield many ‘junk’ cases, alternative approaches to composition are introduced (via notions of tidy, neat, and fastidious retrenchments) that behave better in this regard. These alternatives do however make other issues such as associativity harder. The technical details are presented for vertical composition of ret...

GLANDULAR FEVER, now known as infectious mononucleosis (I.M.), was described in children by Pfeiffer of Wiesbaden in 1889. Byers (1904) wrote of 33 cases in Northern Ireland, which occurred in the age group thirteen months to twenty-five years. An epidemic in a children's ward in Baltimore was reported by Burns (1909). The condition was well reviewed by Tidy and Morley (1921); and in 1923 Tidy ...

Organizations routinely use reported product costs to select their product portfolio. However, these data contain errors because observed cost systems are based on limited information and rely on ad hoc design rules. We employ a numerical experiment to examine the effect of these errors on the quality of the product mix decision and the resulting profit. As decisions change total costs, we cons...

Considerations of the order of magnitude and the symmetry of various intramolecular interactions formthe foundation of molecular spectroscopy. They are related and they together make molecular spectroscopy transparentand tidy. In this chapter, they are discussed starting from the very fundamental. The order of magnitude has not beendiscussed in any previous textbooks of molecular sp...
