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.

Photographing the wave function of the Universe

We show that density fluctuations in standard inflationary scenarios may take the most general non-Gaussian distribution if the wave function of the Universe is not in the ground state. We adopt the Schrödinger picture to find a remarkable similarity between the most general inflaton wavefunction and the Edgeworth expansion used in probability theory. Hence we arrive at an explicit relation bet...

Viewpoint 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 ...

Contrary-to-Duty Obligations

We investigate under what conditions contrary-to-duty (CTD) structures lacking temporal and action elements can be given a coherent reading. We argue, contrary to some recent proposals, that CTD is not an instance of defeasible reasoning, and that methods of nonmonotonic logics are inadequate since they are unable to distinguish between defeasibility and violation of primary obligations. We pro...
