AIMS To explore the enhancing effect of alcohol consumption on attractiveness ratings, in that few studies on the Beer Goggles effect control the stimuli attractiveness level and researchers have seldom considered extending the effect to stimuli other than faces. METHODS Male and female participants (n = 103) were randomly assigned to alcohol consumption or placebo groups. Both groups were as...

in today’s world the concept of “city” without effective landscape is out of imagination. being focal points for human life and activities, cities have to consider the structure and functions which are influenced by natural systems. in this regard, landscapes are inevitable parts of cities with an essential metabolic role. unlike most countries which don’t have to deal with water shortage as a ...

results there was no significant differences between if and conventional mode regarding visibility of mic (p > 0.05). conclusion although using if caused improved visibility of mic, the difference with conventional mode was not statistically different. patients and methods in this cross-sectional study, 2580 digital panoramic images of 18 to 70-year-old patients were inspected for presence of m...

Around the world, thousands of reservoir dams have flooded valleys and become concrete symbols Anthropocene. These landscapes, as well material or immaterial cultural heritages, were thus became invisible, even though they remain in memories local populations. Today, alternative technologies can enable inhabitants to reappropriate these lost heritages and, a way, make them visible again. 3D dig...

In this paper, we are concerned with computing and maintaining the exact visibility polygon V (q) of a moving point observer q in planar scenes represented by a polygon with holes with complexity of n. We propose an algorithm that applies and computes each change to V (q) in constant time as q moves to a new neighboring position. In fact, in our method changes to V (q), as the observer q moves,...

From-region visibility culling is considered significantly harder than from-point visibility culling, since it is inherently 4dimensional. We present a conservative occlusion culling method based on factorizing the 4D visibility problem into horizontal and vertical components. The visibility of the two components is solved asymmetrically: the horizontal component is based on a novel parameteriz...

Recently available near-infrared interferometric data on late-type stars show a strong increase of diameter for asymptotic giant branch (AGB) stars between the K (2.0 − 2.4 μm) and L (3.4 − 4.1 μm) bands. Aiming at an explanation of these findings, we chose the objects α Orionis (Betelgeuse), SW Virginis, and R Leonis, which are of different spectral types and stages of evolution, and which are...

At each shade point, the spherical visibility function encodes occlusion from surrounding geometry, in all directions. Computing this function is difficult and point-sampling approaches, such as ray-tracing or hardware shadow mapping, are traditionally used to efficiently approximate it. We propose a semi-analytic solution to the problem where the spherical silhouette of the visibility is compu...
