Telephone Whistle Alarm

Flights of fear: a mechanical wing whistle sounds the alarm in a flocking bird.

Animals often form groups to increase collective vigilance and allow early detection of predators, but this benefit of sociality relies on rapid transfer of information. Among birds, alarm calls are not present in all species, while other proposed mechanisms of information transfer are inefficient. We tested whether wing sounds can encode reliable information on danger. Individuals taking off i...

Neural Network Tools for Alarm Generation in the Telephone Network Traffic Management

Real-time network traffic management is becoming more and more crucial in Telecommunications. In this paper, we propose a modular system based on neural networks, designed to help the operator for performing diagnosis at different levels of the network. In particular, we focus on local alarm generation at the secondary transit centres of a telephone network. We finally consider some future exte...

Centralized Detection of Pre-alarm State in Telephone Network of Electric Power Utility

In this paper we consider the mixed telephone network of electric power utility consisting of IP, ISDN and Power Line Carrier links. Very important demand in the network is high availability. The central detector of IP and ISDN link failure (pre-alarm) is presented. The detector function is based on the prolonged response time of the network in the case of IP and ISDN link failure. We define un...

Blowing the Whistle

Leniency clauses, offering cartelists legal immunity if they blow the whistle on each other, is a recent anti-trust innovation. The authorities wish to thwart cartels and promote competition. This effect is not evident, however; whistle-blowing may enforce trust and collusion by providing a tool for cartelists to punish each other. We examine the impact of leniency law, and other rules, theoret...
