This paper provides an insight into the usability of our Universal Interaction Controller (UIC), a user interface device designed to support interactions in ubiquitous computing environments equipped with multiple heterogeneous displays. The results are presented of a user study we undertook to test the intuitiveness of Ukey, our UIC input device, comparing it to a wireless gyroscopic mouse, as...

In this paper, application of Sliding Mode Control (SMC) technique for an Active Magnetic Bearing (AMB) system with varying rotor speed is considered. The gyroscopic effect and mass imbalance inherited in the system is proportional to rotor speed in which this nonlinearity effect causes high system instability as the rotor speed increases. Transformation of the AMB dynamic model into regular sy...

Physicists and engineers are making technical progress toward the creation of intercontinental quantum networks. But if they succeed, what new applications will a quantum Internet enable? This paper presents a series of potential uses, some fairly well-established and some highly speculative. The entanglement generated by a quantum network will be useful both as a digital computational resource...

We report a new type of phononic crystals with topologically nontrivial band gaps for both longitudinal and transverse polarizations, resulting in protected one-way elastic edge waves. In our design, gyroscopic inertial effects are used to break the time-reversal symmetry and realize the phononic analogue of the electronic quantum (anomalous) Hall effect. We investigate the response of both hex...

We consider a shape optimization problem in rotordynamics where the mass of a rotor is minimized subject to constraints on the natural frequencies. Our analyis is based on a class of rotors described by a Rayleigh beam model including effects of rotary inertia and gyroscopic moments. The solution of the equation of motion leads to a generalized eigenvalue problem. The governing operators are no...

The nonlinear system of equations of relativistic Lorentz electrodynamics (LED) is studied in a “gyroscopic setup” in which the Lorentz electron is assumed to remain at rest, leaving the electromagnetic fields and the particle spin as the only dynamical degrees of freedom. The global existence and uniqueness of this gyroscopic spin-plus-field dynamics in unbounded space is proven. It is further...

In this paper we derive a nonlinear control law for stabilization of the Furuta pendulum system with the pendulum in the upright position and the rotating rigid link at rest at the origin. The control law is derived by first applying feedback that makes the Furuta pendulum look like a planar pendulum on a cart plus a gyroscopic force. The planar pendulum on a cart is an example of a class of me...

In this paper, the feasibility of a Control Moment Gyroscope (CMG) as balance assistance device is investigated. An inverted pendulum is used as experimental set-up. Our initial results show that it is possible to maintain balance within a 4 degrees range from vertical.

This article presents a novel fuzzy identification method for dynamic modelling of quadrotor unmanned aerial vehicles. The method is based on a special parameterization of the antecedent part of fuzzy systems that results in fuzzy-partitions for antecedents. This antecedent parameter representation method of fuzzy rules ensures upholding of predefined linguistic value ordering and ensures that ...
