The results of the railway track quality assessment, obtained as part diagnostics during its operational phase, are used by construction manager to plan repair activities. aim infrastructure is maintain longest possible good condition structure, most often represented a stable geometry quality. In case low economic efficiency assurance structure through improvement diagnosed parameters, accordi...

We report on the fabrication of a superstructure Bragg grating in a planar polymer substrate. Based on a twofold illumination process an integrated waveguide and a superstructure Bragg grating are subsequently written into bulk polymethylmethacrylate by UV-induced refractive index modification. The measured reflected spectrum of the superstructure Bragg grating exhibits multiple reflection peak...

Some stimuli are perceived as unitary patterns, and others as dual or plural patterns. Such 'unity-and-variety' phenomena are explained by various process approaches of perception, such as the global precedence hypothesis, the preattentive orientation detection assumption, and the recognition-by-components model. However, these three approaches, which will be discussed in this paper, each expla...

In classical sociology, there is a sharp separation between the superstructure reflecting cultural ideals and the concrete Structural Base (SB). The authors hypothesize a Doxical Superstructure (DS) in its own space at a higher level, containing concepts such as completeness, necessity and possibility associated with abstract concepts like beliefs, ethics, knowledge, relations and science. The ...

In view of the weak isolation and shock absorption effect ordinary bearings at present, a new track damping negative-stiffness device was designed based on principle negative stiffness. The stiffness applied to base isolation, system proposed in which track-type NSD common layer were connected parallel. had characteristics clear force transmission, simple structure, self-resetting ability. theo...

This paper presents an approach to dynamic component composition that facilitates creating new composed components using existing ones at runtime and without any code generation. The dynamic abilities are supported by extended type notion and implementation based on additional superstructure provided with its Java API and corresponding JavaBeans components. The new component composition is perf...

BACKGROUND Change theories provide an opportunity for organizational managers to plan, monitor and evaluate changes using a framework which enable them, among others, to show a fast response to environmental fluctuations and to predict the changing patterns of individuals and technology. The current study aimed to explore whether the change in the public accounting system of the Iranian health ...
