The combination of a disulfonated-dibenzo-24crown-8 ether wheel and a dicationic 1,2-bis(pyridinium)ethane axle yields a neutral [2]pseudorotaxane which in combination with neutral metallic units such as a Cu(II)benzoate paddlewheel or Cu(I)Br unit yields one-dimensional coordination polymers (linear and bent) which are the first examples of charge neutral, metal-organic rotaxane frameworks.

This paper discusses impact of changes in the load size and distribution passenger cars on geometry suspension steering systems. It was found to have a major road safety. The research carried out with four most popular system designs used modern cars, i.e. multi-link both front rear axles, only axle, axle simple design for axles. Eight variants were tests. Changes following wheel parameters ide...

The incorporation of a linear D–π–A “push–pull” chromophore synthesized by Knoevenagel condensation as axle rotaxane is reported.

This paper introduces a method for counting vehicle axles in the video sequence appropriate for use in vision-based automatic vehicle classifiers with narrow field of vision. The procedure is simple, robust to wheel detector errors, and computationally efficient due to the use of the fast Hough transform. It provides a self-test for applicability for detection of cases where it is not applicabl...

Axle bearings of railway car bogies are important parts that support the running cars. It is desirable to detect damage axle at an early state. Therefore, autonomous detection system (ADDS) was developed does not require a power supply nor wiring and notifies bearing vehicle. The ADDS utilized anti-vibration rubber with built-in piezoelectric element wireless transmitter; which installed on box...

In the framework of an ongoing national research project involving the University of Minho, the National Laboratory of Civil Engineering and the New University of Lisbon, different commercial FEM codes (DIANA, PLAXIS and ANSYS) were tested to model the dynamic performance of a high speed train track. Initially a plain strain model is considered in a robin test using experimental data from a wel...
