Government Debt as Insurance against Macroeconomic Risk Is there a role for debt beyond curing overaccumulation of capital? Does dynamic efficiency and the infeasibility of debt Ponzi schemes eliminate any Pareto-improving role for a government in a competitive economy with complete markets? Is there an optimal maturity structure of public debt? Using a stochastic Diamond OLG model, we tackle t...

We introduce a robot-safety device system attended by two di erent repairmen. The twin system is characterized by the natural feature of cold standby and by an admissible “risky” state. In order to analyse the random behaviour of the entire system (robot, safety device, repair facility), we employ a stochastic process endowed with probability measures satisfying general steady-state di erential...

The behaviour in terms of robustness during turn-off of power IGBT modules is presented. The experimental characterisation is aimed to identify the main limits during turn-off in power IGBT modules in typical hard switching applications. In this paper an experimental characterization of high power IGBT modules at output currents beyond RBSOA, at high junction temperatures and under different dr...

WHO defines Safe Injection, as an injection that does no harm to recipients; does not expose the health care worker to any risk; and does not result in waste that is dangerous for the community. In India, 300 crore injections are given in an year out of which 180 crore are unsafe; diseases transmitted through unsafe injection practices include hepatitis B: 21million, hepatitis C: 2 million, and...

Intrusion detection systems are fundamentally passive and fail–open. Because their primary task is classification, they do nothing to prevent an attack from succeeding. An intrusion prevention system (IPS) adds protection mechanisms that provide fail–safe semantics, automatic response capabilities, and adaptive enforcement. We present FLIPS (Feedback Learning IPS), a hybrid approach to host sec...
