Redundant system with three two-degree-of-freedom (2-DOF) inertial sensors is one of the possible candidates for the UAV inertial sensor redundancy management system. In the conventional FDI techniques using hardware redundancy, at least four 2DOF inertial sensors are needed to detect and isolate the faulty sensor. Since two input axes of 2-DOF inertial sensors are mechanically correlated with ...

Structural failures in recent earthquakes and hurricanes have exposed the weakness of current design procedures and shown the need for new concepts and methodologies for building performance evaluation and design. A central issue is proper consideration and treatment of the large uncertainty in the loadings and the complex building behavior in the nonlinear range in the evaluation and design pr...

In high-density sensor networks, scheduling some sensor nodes to be in the sleep mode while other sensor nodes remain active for monitoring or forwarding packets is an effective control scheme to conserve energy. In this paper, a Coverage-Preserving Control Scheduling Scheme (CPCSS) based on a cloud model and redundancy degree in sensor networks is proposed. Firstly, the normal cloud model is a...

For redundant robot kinematics we construct an extended Jacobian inverse that approximates the Jacobian pseudo-inverse. Our construction relies on the approximation of codistributions associated with the Jacobian pseudo-inverse by an integrable codistribution, spanned by differentials of certain functions that serve as components of the augmenting kinematics map in the extended Jacobian inverse...

In this paper, we show the redundancies of multiset topological spaces. It is proved that $(P^star(U),sqsubseteq)$ and $(Ds(varphi(U)),subseteq)$ are isomorphic. It follows that multiset topological spaces are superfluous and unnecessary in the theoretical view point.

Partitioning the pupil reduces the degree of baseline redundancy, and therefore improves the quality of images that can be obtained from the system. A practical realization of this approach uses an aperture partitioning element at an aft optics pupil of the optical system. This paper describes the design, implementation and testing of a new aperture partitioning element that is completely refle...

We present a general holistic theory for the organization of complex networks, both human-engineered and naturally-evolved. Introducing concepts of ‘value’ of interactions and ‘satisfaction’ as generic network performance measures, we show that the underlying organizing principle is to meet an overall performance target for wide-ranging operating or environmental conditions. This design or surv...

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...

These instructions give you guidelines for preparing papers for the journal Engineering Letters. Use this document as a template if you are using LaTeX. Motion tracking and object recognition often use cameras that are mounted in motion platforms like pan-tilt units, linear tables and even robots. Tracking can be automated by visually servoing the platform’s degrees-of-freedom (DOF) thus keepin...
