Complete shaking force and shaking moment balancing of spatial multibody systems with open kinematic chains [PDF]
This paper deals with a solution for the problem of full shaking force and shaking moment balancing of spatial multi body systems with open kinematic chains. Firstly, the general conditions for complete dynamic balancing of spatial multibody systems are

We consider the problem of attitude stabilization for a low Earth orbit satellite having only electromagnetic actuation. Such a satellite is not fully actuated, as the control torque is the cross-product of magnetic moment due to magnetorquers and the ...

Embry truncated complex moment problem
Let T be a cyclic subnormal operator on a Hilbert space H with cyclic vector x0 and let γij:=(T*iTjx0,x0), for any i,j∈N∪{0}. The Bram–Halmos’ characterization for subnormality of T involved a moment matrix M(n).

Observer Design for a Variable Moment of Inertia System
Variable moment of inertia systems are common, and a popular laboratory system of this type is the “ball-and-beam”. Such systems are, however, nonlinear and often unstable. Efficient control requires full state information (or at least partial velocities)

The analysis of medium-sized arrays of complex elements using a combination of FDTD and reaction matching [PDF]
The analysis of medium-sized arrays of complex antenna elements by means of a full-wave technique often requires impractical amounts of computer power. Nevertheless, it is essential that all the mutual couplings between elements are taken into account. A

Comparative study on the mechanical mechanism of confined concrete supporting arches in underground engineering. [PDF]
In order to solve the supporting problem in underground engineering with high stress, square steel confined concrete (SQCC) supporting method is adopted to enhance the control on surrounding rocks, and the control effect is remarkable.

A Gimballed Control Moment Gyroscope Cluster Design for Spacecraft Attitude Control
This paper addresses the problem of singularity avoidance in a cluster of four Single-Gimbal Control Moment Gyroscopes (SGCMGs) in a pyramid configuration when used for the attitude control of a satellite by introducing a new gimballed control moment ...

Data for indirect load case estimation of ice-induced moments from shaft line torque measurements
During ice navigation, blade measurements of ice-induced moments on ship propellers, are challenged by the harsh operating environment. To overcome this problem, shaft line measurements are performed inboard, and the required propeller loads are ...
