We investigate the large deformation and extreme load-management capabilities of a soft topologically polarized kagome lattice mapped to cylindrical domain through problem wheel rolling on an irregular surface. test surface–lattice interaction experimentally by subjecting 3D-printed topological prototype localized distributed boundary loads. This investigation reveals dichotomy in force transfe...

A cyclodextrin ring was face-selectively transferred between two stations linked by a 2-methylpyridinium group on an axle molecule.

Abstract This document reports a probabilistic approach for residual fatigue life predictions of cracked railway axle with allowance variability the input data. A NASGRO formulation was used such purpose, its main parameters considered as uncorrelated random variables varying in given ranges. load spectrum order to take into account actual loading conditions that these components undergo. The p...

Bicycles have been recognized for their advantages such as low environmental impact, health improvement, and maintenance of transportation function in times disaster, demand bicycles is increasing social conditions change. The pedaling a conventional bicycle nowadays turns crank to rotate the front gear, which transmitted rear gear by chain, axle wheel. Since require human power pedal, structur...

There is a need for vehicles to maneuver when there are traffic jams, overcome narrow streets and various obstacles. This leads increased requirements dynamism maneuverability of vehicles.
 The authors present the results development research steering control vehicle, which provides maneuverability. Such circumstances significantly affect increase in wheeled vehicles, including tractors, u...

[2]- and [3]-rotaxanes with a tetraphenoxy perylene diimide core were synthesized. Hydrogen bonding between the wheel and the imide changes the optical properties of the perylene chromophore: the absorption and fluorescence spectra are red-shifted. The decay times of the rotaxanes are shorter in comparison with that of the axle. Single molecule fluorescence measurements reveal relatively narrow...

Over the past twenty years; road traffic (both passenger and freight) has grown significantly in Pakistan. Higher axle loads and repetitions have resulted in premature rutting of flexible pavements. Rutting, in the form of shear flow is a typical distress that mainly attributed to increased tire pressure, high temperature and heavy axle loads. Consequently, National Highway Authority (NHA), Pak...
