Theory and Applications of Self-Tuning Regulators

This paper reviews work on self-tuning regulators. The regulator algorithms, their theory and industrial applications are reviewed. The paper is expository—the major ideas are covered but detailed analysis is given elsewhere.

First attempt to monitor atmospheric glyoxal using differential absorption lidar

Glyoxal (CHOCHO), as an indicator of photochemical “hot spots”, was for the first time the subject of a differential absorption lidar (DIAL) campaign. The strongest absorption line of glyoxal in the blue wavelength region – 455.1 nm – was chosen as the experimental absorption wavelength. In order to handle the effects of absorption cross-section variation of the interfering gas – nitrogen dioxide

Have children become negotiators?

Abstract. The source material consists of interviews with twenty Scandinavian children aged seven and eight. The interviews focus on two issues: first, the way in which the children describe their participation at home in decisions about food and meals; and second, children's housework. The qualitative data has been supplemented with various quantitative studies: we consider the children’s attitud
