Mobility and reduction of industrial activity time is one of the major requirements raised to modern systems of automation. One of the most effective ways of achievement of this purpose is vertical integration with use of wireless technologies. The lab set – model of vertical integration for data gathering from the intellectual Profibus РА sensor, Profibus DP data transmission, controllers conf...

Some personal reminiscences of Olga Taussky-Todd

Olga - a conversational agent with gestures

The Olga project has developed an animated agent interface for information services. The interface combines a graphical interface, spoken dialogue and an animated 3D ‘human-like’ character for multimodal input and output. The interaction is intelligently managed using techniques derived from spoken dialogue but extended for the graphical modality. The Olga agent is innovative in combining a spo...

Timoshenko Systems with Indefinite Damping

We consider the Timoshenko system in a bounded domain (0, L) ⊂ R1. The system has an indefinite damping mechanism, i.e. with a damping function a = a(x) possibly changing sign, present only in the equation for the rotation angle. We shall prove that the system is still exponentially stable under the same conditions as in the positive constant damping case, and provided a = ∫ L 0 a(x) dx > 0 and...
