Estimations of daylight factors, used to calculate energy savings, typically do not consider occupants’ use of window blinds. The data indicate that such estimations should include some assessment of window blind usage, because over half of the window area is usually occluded in some way by blinds. It appears that many occupants purposely use window blinds to sunlight from penetrating their wor...

a survey on the cause of blindness in iran was carried out among 870 blinds from all parts of the country. 305 people with the same cause, 27 with different causes were blind from both eyes and 538 were blind from one eye. in present paper the first ten causes of blindness is pointed out and these causes are compared in the three different zones of ten countries, also the cause of blindness in ...

Venetian blinds play an important role in controlling daylight in buildings. Automated blinds overcome some limitations of manual blinds; however, the existing automated systems mainly control the direct solar radiation and glare and cannot be used for controlling innovative blind systems such as split blinds. This research developed an Illuminance-based Slat Angle Selection (ISAS) model that p...

People increasingly need to work collaboratively across a distance. Although telecommunication technologies offer sophisticated audioand video support, signaling awareness of the remote parties’ availability in a videoconferencing environment is still not uniformly agreed upon. The opening and closing of blinds in a collocated office environment however sends a strong signal about privacy, avai...

~ T M C ~ . R a p t o r diet is most commonly measured indirectly, by analyzing castings and prey remains, or directly, by observing prey deliveries from blinds. Indirect methods are not only time consuming, but there is evidence to suggest these methods may overestimate certain prey taxa within raptor diet. Remote video surveillance systems have been developed to aid in monitoring and data col...

The finger motions and quickness of braille reading were investigated by way of recording the finger tip pressure on the braille and its time process. Subjects were separated into two groups. One group consisted of 5 experienced blinds and the other group consisted of 5 blinds who were beginners in braille reading. The comparison of obtained results from two groups gave some evidence for the fo...

Alleles causing colour-blindness are present in humans at non-negligible levels, and it is not yet understood how colour-blindness is maintained, since colour-vision probably provides a selective advantage, e.g. when foraging. We show that after dark-adaptation colour-blinds had lower light perception thresholds than colour-normals (0.44 log-units), which may give a selective advantage under sc...
