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...
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...
Continuously welded rails (CWR) are sensitive to thermal and train loads which could destabilize the track cause buckling. The study of buckling in literature, however, is mostly focused on static analysis CWR tracks under loads. Yet reality, dynamic lateral, vertical longitudinal directions can have a major impact behaviour. Moreover, wheel defects aggravate interaction loads, reduce safety ag...
Abstract The numerical and computation aspects of the Knife-edge Equivalent Contact ( KEC ) constraint lookup table LUT methods are compared in this paper. method implementation uses a penetration-based elastic contact model for flange constraint-based formulation at wheel tread. For method, where an infinitely narrow rail contacts equivalent wheel, regularization tread-flange transition is ado...
GENERALLY, the force of gravity has little or no effect upon the distribution of the various materials within cells, although they may differ considerably in their relative specific gravity. However, by means of the centrifuge forces can be obtained many times greater than gravity, which otherwise exist only on the very largest planets. Because of this fact, the centrifuge has proved to be a ve...
A continuous periodic motion stimulus can sometimes be perceived moving in the wrong direction. These illusory reversals have been taken as evidence that part of the motion perception system samples its inputs as a series of discrete snapshots -although other explanations of the phenomenon have been proposed, that rely on the spurious activation of low-level motion detectors in early visual are...
