A dropshaft is an energy dissipator connecting two channels with different invert elevations. Detailed air-water flow and acoustic measurements were conducted in a prototype dropshaft under controlled flow conditions, and complemented by a 1:3.1 scale model study. Experimental observations showed three flow regimes with distinct acoustic signatures. Strong flow aeration was recorded in two flow...

The author premises that the emotions as representative states of consciousness have physiological conditions similar to those aroused by the original excitations, and that physical agents which modify the one can, in like manner, modify the other. He then sets forth that this similitude of somatic states helps to establish the physical nature, normal or abnormal, of the mind, and to indicate t...

The effects of acetazolamied on the cerebral circulation and metabolism was previously shown to be due to a raised PCO2 in brain tissue. The effects of the drug on the human electroretinogram (ERG) are investigated in fifteen human volunteer subjects. A significant increase in the b-wave was found. A similitude with the mechanism of acetazolamide administration in brain and retinal tissue seems...

In this paper we propose a system for the recommendation of tagged pictures obtained from the Web. The system, driven by user feedback, executes an abductive reasoning (based on WordNet synset semantic relations) that is able to iteratively lead to new concepts which progressively represent the cognitive creative user state. Furthermore we design a selection mechanism to pick the most relevant ...

Iteration is involved in the fields of dynamical systems and numerical computation and so forth. The computation of iteration is difficult for general functions even for some simple functions such as linear fractional functions . In this paper, we discuss fractional polynomial function and use the method of conjugate similitude to obtain its expression of general iterate of order n under two di...

After light adaptation, all "on-center" ganglion cells in the dark became "red on-center," and all "off-center" cells turned into "red off-center" cells. On a chance basis, this similitude of effect between the rods and the red cones in opponent color cells was not expected. These findings indicate that in the goldfish there is some similarity between the connections of the rods and of the long...

‎We provide a uniform estimate for the $L^1$-norm (over any interval of bounded length) of the logarithmic derivatives‎ ‎of global normalizing factors associated to intertwining operators for the following reductive groups over number fields‎: ‎inner forms of $operatorname{GL}(n)$; quasi-split classical groups and their similitude groups; the exceptional group $G_2$‎. ‎This estimate is a key in...
