In contrast, a non-Lyapunov framework is employed here to derive new and more general L2-stability conditions in the frequency domain. These conditions have the following features:i) They are expressed in terms of the positive definiteness of the real part of matrices involving the transfer ...
Absolute frequency measurement of an I-2 stabilized Nd : YAG optical frequency standard A frequency (in-)stability of 2.5×10τhas been measured in the optical domain against a hydrogen maser. The measured (in-)stability decreases to 1×... GD Rovera,F Ducos,JJ Zondy,... - 《Measurement...
However, the energy in the haptic system is not directly measurable, but estimated from some measured quantities such as force and velocity; therefore, the estimated energy is occasionally inaccurate. To resolve this problem, a new observer, working in the frequency domain, is proposed in this ...

In this study, 12 subjects provided gait information over various surfaces while wearing an IMU. Instabilities were determined by comparing frequency domain data over less stable surfaces to frequency domain data of neural network (NN) models representing the normal gait for any given participant. ...
