Iran is worried about the contagion effect of the Saudi military intervention in Yemen, that is, Tehran fears the experience, once successful, may be repeated elsewhere in the Middle East, particularly Syria, hence its stiff opposition and harsh reactions to it.

Technological change and users: An actor-network perspective on the digitalization of video surveillance

This paper discusses aspects of technological change and the path towards institutionalization of new innovations, with a focus on how users matter and are part of the co-construction of such change. An empirical example from the security industry is used to illustrate how two distinct phases in the analog-to-digital shift in video surveillance technology have had very different outcomes with resp

Impersonation - reproduction of speech

The present paper is a study of one impersonator and one of his voice imitations in order to find out how he changes his own voice and speech behaviour in order to get close to the target voice. Preliminary results from the auditory and the acoustic analysis, focusing on speech style and intonation pattern, will be presented.

Temperature control of a utility system for an Open Plate Reactor

A new reactor type has been designed by Alfa Laval AB,the open plate reactor (OPR). It combines good mixing with high heat transfer capacity. With the new open plate reactor, highly exothermic reactions can be produced using more concentrated reactants. In the paper, the reactor type is presented and a model from first principles is derived. The paper concerns the control properties of the platere

Designing Bandwidth-Efficient Stabilizing Control Servers

Guaranteeing stability of control applications in embedded systems, or cyber-physical systems, is perhaps the alpha and omega of implementing such applications. However, as opposed to the classical real-time systems where often the acceptance criterion is meeting the deadline, control applications do not primarily enforce hard deadlines. In the case of control applications, stability is considered
