The synthesis of a peptide-containing lasso molecular switch by a self-entanglement strategy is described. The interlocked rotaxane molecular machine consists of a benzometaphenylene[25]crown-8 (BMP25C8) macrocycle surrounding a molecular axle. This molecular axle contains a tripeptidic sequence and two molecular stations: a N-benzyltriazolium and a pH-sensitive anilinium station. The tripeptid...

Usually, vehicles driven under diierent road conditions are subjected to various forces and moments. An uneven input force originating from road surface could be one of the major load aaecting ride comfort or body vibration. In order to investigate the ride and handling characteristics of a tandem axle truck, a three dimensional mathematical model is developed, and the equations of motion for t...

Significant errors of train axle generators (tachometers) are due to wheel slip and slide. In this paper, an algorithm is designed to compensate for these errors. The algorithm identifies the wheel slip and slide by examining the variation of the processed vehicle longitudinal acceleration. Whenever wheel slip/slide is identified, then the vehicle speed is adjusted if a certain condition is met...

The synthesis of the first halogen bonding [3]rotaxane host system containing a bis-iodo triazolium-bis-naphthalene diimide four station axle component is reported. Proton NMR anion binding titration experiments revealed the halogen bonding rotaxane is selective for nitrate over the more basic acetate, hydrogen carbonate and dihydrogen phosphate oxoanions and chloride, and exhibits enhanced rec...

In the paper we address a problem of controlling an oscillating motion with a robot. As the object we have selected a yo-yo. Yo-yo is a toy made of two discs connected with a short thin axle, which can be moved up and down by moving a string tied to the axle. Although it is very easy to play with yo-yo for a human, designing a control system for a robot is quite a challenge. We present a simpli...

We describe the preparation of a compound whose molecules consist of two metal sandwich stands carrying tentacles with affinity to metal surfaces and holding an axle that carries a dipolar or a nonpolar rotator. The dipolar rotor exists as three pairs of enantiomers, rapidly interconverting at room temperature. When mounted on a gold surface, each molecule represents a chiral altitudinal rotor,...

In this paper, the kinematic model of an autonomous mobile robot system consisting of a chain of steerable cars and passive trailers with axle-to-axle hitching is examined and converted into a multi-input chained form using dynamic state feedback. Some of the methods which have been proposed for steering two-input chained form systems are generalized to multi-chained systems, and then applied t...
