In movies or on TV, a wheel can seem to rotate backwards, due to the temporal subsampling inherent in the recording process (the wagon wheel illusion). Surprisingly, this effect has also been reported under continuous light, suggesting that our visual system, too, might sample motion in discrete "snapshots." Recently, these results and their interpretation have been challenged. Here, we investi...

The fact that a perceptual experience akin to the familiar wagon-wheel illusion in movies and on TV can occur in the absence of stroboscopic presentation is intriguing because of its relevance to visuo-temporal parsing. The wagon-wheel effect in continuous light has also been the source of considerable misunderstanding and dispute, as is apparent in a series of recent papers. Here we review thi...

Let S be a set of n points in Rd in general position. A set H of k-flats is called an mk-stabber of S if the relative interior of any m-simplex with vertices in S is intersected by at least one element of H. In this paper we give lower and upper bounds on the size of minimum mk-stabbers of point sets in Rd and in general position. We study mainly mk-stabbers in the plane and in R3.

Original scientific paper This paper presents the S-N approach to fatigue failure analysis of welded joints that integrates well with finite element modelling. Goodman's criterion and fatigue criterion based on the equivalent stress range were used for the analysis of the fatigue failure. Goodman's criterion and fatigue criterion based on the equivalent stress range, for determining fatigue saf...

Central Appalachia residents present unique healthcare challenges. This vulnerable population faces poor health status and low access to health care. 'The Health Wagon' was established to innovatively enhance access to health care for the poor and marginalized rural population of Central Appalachia. This article describes the operations of the Health Wagon, a full mobile medical clinic, in deli...

The wagon flow scheduling plays a very important role in transportation activities in railway bureau. However, it is difficult to implement in the actual decision-making process of wagon flow scheduling that compiled under certain environment, because of the interferences of uncertain information, such as train arrival time, train classify time, train assemble time, and flexible trainsize limit...

Quentin Skinner is an intellectual historian known for his pioneering work on early-modern European political thought. He was educated at Bedford School and Gonville and Caius College, Cambridge. Author of such works as The Foundations of Modern Political Thought (1978) and Visions of Politics (2002) he served as the Regius Professor of History at the University of Cambridge, and currently as t...

An articulated covered wagon design was developed. The feature is that the body-bearing elements are made of circular pipes. This technical solution it possible to reduce tare weight while ensuring strength conditions. Mathematical simulation dynamic loading developed carried out under main operating In calculations observed quantities, an application symmetry with regard longitudinal axis used...

The use of fibre reinforced composite materials is one method by which the lightweighting rail vehicles can be achieved. However, issue impact damage, amongst other challenges, limits their safety certification. This accentuated high levels loading a vehicle may subjected to during service. paper addresses significance pre-tension on large structures, specifically for redesign pressure vessel f...
