Photographing a Time Interval
A method of measuring time intervals by a single observer proposed by Crowell[3] is extended to the more general case when the events separated by the time interval take place at two points characterized by the same y=y' space coordinates. We show that time dilation and time contraction can take place or even an inversion in the time succession can be detected.

between species, but between different segments on the same animal. They have limbs specially adapted for walking, eating, grooming, swimming, mating, sensing the surrounding environment, brooding young, spearing prey, scraping surfaces and even snapping to make noise. Lobsters provide a good example of the limb diversity that can exist on even a single individual — the thoracic and abdominal a...
متن کاملViewpoint Selection for Photographing Architectures
This paper studies the problem of how to choose good viewpoints for taking photographs of architectures. We achieve this by learning from professional photographs of world famous landmarks that are available on the Internet. Unlike previous efforts devoted to photo quality assessment which mainly rely on 2D image features, we show in this paper combining 2D image features extracted from images ...
متن کاملAntioxidant Defences in Planktonic Crustaceans Exposed to Different Underwater Light Irradiances in Andean Lakes
In freshwater environments direct biological effect of ultraviolet radiation (UVR) result from absorption of specific wavelengths by macromolecules and alteration of biochemical processes. Indirect effects are related to UVR interaction with water and dissolved organic carbon to form chemically reactive species (ROS: reactive oxygen species). Zooplankton photoprotection includes mycosporine-lik...
متن کاملOn techniques for stabilising and photographing skulls.
The design and use of a small light portable craniostat is described. Made of clear polystyrene, with adjustable pegs of the same material, the device is small, light, unbreakable and easily portable. It facilitates rapid and stable positioning of skulls in any position for study of photography.
