Experimental studies of spatial input devices have focused on demonstrating either the superiority of 3D input devices over 2D input devices, or the superiority of bimanual interaction over unimanual interaction. In this paper, we argue that hybrid interfaces that combine a 3D input device with a 2D input device have received little attention up to now and are potentially very useful. We demons...

In the design and evaluation of speech input/output dialogues for control of PBX features, various issues were encountered which could not be resolved by reference to the available literature. This paper outlines solutions to some generic issues in speech dialogue design in the form of Generic Dialogue Modules. These are descriptions of procedures which may be implemented in a wide range of spe...

We present results concerning the parameter estimates obtained by prediction error methods in the case of input signals that are insuuciently rich when considered locally in time. As is intuitively obvious, the data located in time intervals where the system excitation is poor carry only an incomplete information about the system input-to-output (I/O) dynamics. In noise undermodeling situations...

To account for the input-model and input-parameter uncertainties inherent in many simulations as well as the usual stochastic uncertainty, we present a Bayesian input-modeling technique that yields improved point and confidence-interval estimators for a selected posterior mean response. Exploiting prior information to specify the prior probabilities of the postulated input models and the associ...

We consider a queuing model with the workload evolving between consecutive i.i.d. exponential timers {e q }i=1,2,... according to a spectrally positive Lévy process Yi(t) that is reflected at zero, and where the environment i equals 0 or 1. When the exponential clock e (i) q ends, the workload, as well as the Lévy input process, are modified; this modification may depend on the current value of...

In this paper we provide a rather complete set of passivity suuciency conditions that give asymptotic stabilizability of nonlinear cascades of driving-driven systems. Moreover, we analyze the input-output and input-to-state stability properties of existing stabilization schemes. This allows us to derive the weakest passivity assumption on the driving system that give the required stability. In ...

The transfer function of a linear mechanical system can be defined in terms the quadruplet state-space matrices (A,B,C,D) that identified from input and output measurements with subspace-based identification methods. estimation has been well studied literature both theoretical practical viewpoints. Nonetheless, algorithm for uncertainty quantification its errors resultant parametric is missing ...
