We report the observation of quantized rotational states of a diatomic C2 unit in solid endohedral fullerene C(2)Sc(2)@C(84). The rotational transitions induce a periodic line pattern in the low energy Raman spectrum. The rotational constant B and the C-C distance were found to be 1.73 cm(-1) and 0.127 nm, respectively.

Mechanics and control of innovative gyroscopic structural systems are detailed in the paper. By adding controllable spinning wheels to a network of controllable, axially loaded strings and bars, it is shown that the mobility and manipulation of the structural system are enhanced.

Stabilization of Gyroscopic Systems
ZAMM, 2001The authors consider systems of singularly perturbed linear ordinary differential equations which can be considered as equations of linear autonomous gyroscopic systems with stabilizing control. The results in the paper are mainly of methodological interest.

Abstract With the development of low loss single mode optical fiber waveguides, it is possible to construct a gyroscope using optical fibers. The configuration is a multi-turn Sagnac interferometer. Light from an external source is split and injected into the fiber ends, travels in clockwise and counterclockwise directions and is recombined to form ...

Consideration is given to the nonlinear terms in the differential equations governing the motion of gyroscopes under constant acceleration and a “correcting” torque. Unstable oscillations are noted when a correcting torque is present and the nonlinear terms are included.

This paper investigates the dynamics of a novel “multisensor” comprising a two-axis gyroscope and a single-axis linear accelerometer. The theoretical analysis indicates that the gyroscope has two modes of operation, untuned and tuned, offering, respectively, angular rate and angular displacement measurement capability, depending on the damping and ...

The paper examines the performance of a new two axis dynamically tuned gyroscope. Two types of feedback loop are described. In the first design the control force maintains the sensitive element in a near null position and provides a direct measure of the applied rate. Errors arising because of mistuning and damping are evaluated.

Abstract After a brief review of the fundamental kinetic equations of gyroscope motion, the following topics are considered: (a) The erection of an electrically driven gyroscope when an electrical torque is applied. (b) The effect of inequality of the principal moments of inertia normal to the spin axis, on gyroscope motion.
