A riderless bicycle can automatically steer itself so as to recover from falls. The common view is that this self-steering is caused by gyroscopic precession of the front wheel, or by the wheel contact trailing like a caster behind the steer axis. We show that neither effect is necessary for self-stability. Using linearized stability calculations as a guide, we built a bicycle with extra counte...

We demonstrate how we can take advantage of employee information and digital traces of interaction in order to provide personalized recommendations of content to enterprise users. In particular, we focus on the cold start problem encountered when a service lacks relevant data to base recommendations. Our recommendation service – Steer – first seeks out user preference data. In the absence of su...

FlexRay, as a communication protocol for automotive control systems, is developed to fulfill the increasing demand on the electronic control units for implementing systems with higher safety and more comfort. In this work, we study the impact of radiation-induced soft errors on FlexRay-based steer-by-wire system. We injected the soft errors into general purpose register set of FlexRay nodes to ...

A high degree of reliability is a basic necessity for all critical elements of a vehicle. This is particularly true for the systems used to control or steer the vehicle. Numerous steer by wire (x-by-wire) concepts were developed over the years, but for a variety of reasons, none were ever implemented. Most of them considered only standard single microcontroller system architectures with a low d...

Organic steer production demand several decisions concerning grazing strategy, feeding level in the winter and factors as slaughter weight and length of the fattening period. The production can be difficult to optimise, therefore the objective of this study was to describe a model developed to optimise the fattening and slaughter strategy of steer production concerning economy at an individual ...

This paper describes a method for controlling a vehicle steer-by-wire system. It gives a novel control structure for the steer-by-wire system to implement steering functions and to improve the vehicle handling performance. The paper focuses on the implementation of various steering functions by applying control design methods. Some vehicle test results are included.
