Title The effect of illumination and stage of tide on the attachment of barnacle cyprids Type Journal Article
Year 1947 Publication The Biological Bulletin Abbreviated Journal (up)
Volume 93 Issue 3 Pages 240-249
Keywords animals
Abstract 1. The cyprid larvae of Balanus improvisus were found to settle in a diurnal rhythm with maximum numbers attaching during daylight hours.

2. No consistent pattern of vertical distribution of the cyprids was found.

3. The normal diurnal cycle in rate of attachment of barnacle cyprids was nullified by the use of artificial illumination over the collecting surfaces at night.

4. The magnitude of the cyprid collection on the artificially illuminated surfaces was equal to the collection on the sun-illuminated surfaces in daylight.

5. The intensity of artificial light necessary to produce large cyprid attachments at night was of an order as low as 1 footcandle at the water surface.

6. No correlation was found between the quantity of artificial light at night and the numbers of cyprids attached.

7. The highest rate of cyprid attachment relative to the phase of the tide was found to occur when the waters of upper Biscayne Bay were sampled at the collecting station. This body of water reached the sampling station at low tide and was characterized by a high cyprid population.

Title The daily activity patterns of mayfly nymphs (Ephemeroptera) Type Journal Article
Year 1968 Publication Journal of Zoology Abbreviated Journal (up)
Volume 155 Issue 2 Pages 201-221
Keywords Animals
Abstract Nymphs of Baëtis rhodani (Pictet), Ephemerella ignita (Poda), Ecdyonurus venosus (Fabricius), Rhithrogena semicolorata (Curtis), and Heptagenia lateralis (Curtis) showed a similar endogenous rhythm of activity under conditions of natural illumination, continuous light and continuous darkness; and were most active at night when they moved from the lower to the upper surface of the stone. The nymphs were positively thigmotactic and negatively phototactic in flowing water, but these taxes and the endogenous activity rhythm of all species except Heptagenia lateralis changed markedly when the flow of water ceased.

Title A New Light Control Method with Charge Induction of Moving Target Type Journal Article
Year 2019 Publication IEEE Sensors Journal Abbreviated Journal (up)
Volume 19 Issue 16 Pages
Keywords Lighting; Instrumentation
Abstract Intelligent lamp control system has been widely studied all over the world because of its energy saving and social effect. In this paper, a new intelligent lamp control method based on charge induction for moving target is proposed. The detection model is established with the surface charge induction and verified by a luggage detection experiment. The intelligent lamp control system using the detection method is carried out. The performance of the system demonstrates that the proposed method can detect the moving target at any orientation whatever with or without occlusion and the detection distance can reach more than 3 m for the pedestrian.
