Based on the knowledge of dimensional and mass features a forwarder, model was developed to assess its mobility during timber forwarding uphill in safe eco-efficient way. The is based position forwarder’s centre gravity, declared payload length loaded timber, as well gradeability for traction characteristics vehicle. connects two research approaches, (1) vehicle–terrain approach (distribution a...

We examine a rod piston-rotaxane system, where the positions of several mobile rings on the axle are controlled by an external force acting on one of the rings. This allows us to access the translational entropy of the rings. For a simple rotaxane molecule with an axle that has uniform ring-axle interactions along its length, the molecule behaves like a miniature piston filled with a one-dimens...

Finite element method in pavement analysis is a type of mechanistic analysis that has widely been used by road and transportation engineers these days. This method is used with related programs such as ABAQUS/CAE which is one of the powerful software on this task. Modeling in this software has been developed from 2D static models to 3D dynamic models which are closer to reality due to the more ...

Weigh-in-motion (WIM) devices record vehicle axle loads on highways. WIM data include loads, inter-axle spacings, classification, gross weights, length, and travel speed. Pavement design, management, performance studies all require data, directly as a spectrum or indirectly standard axles. In 2016, 132 were operating California’s highway network, one of the densest best-maintained clusters in U...
