This paper introduces a new dynamical model which enhances the relationship between face movements and speech acoustics. Based on the autocorrelation of the acoustics and of the face movements, a causal and a non-causal filter are proposed to approximate dynamical features in the speech signals. The database consisted of sentences recorded acoustically, and by using a Qualisys system to capture...

This paper addresses some of the issues involved in modeling the domain of turbojet engine operation. A causal model based on the relationships between engine parameters has been developed and used to implement an engine simulation. The implementation includes a facility for explaining the results of the simulation.

The coding problem for wiretap channels (WTCs) with causal and/or non-causal channel state information (CSI) available at the encoder (Alice) decoder (Bob) is studied, particularly focusing on achievable secret-message secret-key (SM-SK) rate pairs under semantic security criterion. One of our main results summarized as Theorem 3 inner bounds SM-SK pairs, which follows immediately by leveraging...

This article presents an integrated model of contentious nationalist activity, with structure, politics, and action assuming equal roles in an interdependent causal system. The model is tested using simultaneous equation systems on 130 ethno-nationalist groups from 1990 to 1998. The results confirm the vital, indirect role of grievances and group identity on protest and the powerful direct and ...
