In cases of power outages the communication of organizations responsible for recovery work (emergency services, public administration, energy network operators) to the public poses several challenges, primarily the breakdowns of many communication infrastructures and therefore the limitations of the use of classical communication media. This paper surveys technical concepts to support crisis co...

This paper discusses the application of machine learning to the design of power system blackout prediction criteria, using a large data base of random power system scenarios generated by Monte-Carlo simulation. Each scenario is described by temporal variables and sequences of events describing the dynamics of the system as it might be observed from realtime measurements. The aim is to exploit t...

During re-entry into earth’s atmosphere, a spacecraft suffers from loss of communication with the ground control station, known as communication blackout, due to formation of plasma around the re-entry spacecraft. This paper presents the theory and analysis of the communication blackout and its mitigation using static magnetic field method. The interaction between electromagnetic waves and plas...

BACKGROUND Little is known about how power outages affect health. We investigated mortality effects of the largest US blackout to date, 14-15 August 2003 in New York, NY. METHODS We estimated mortality risk in New York, NY, using a generalized linear model with data from 1987-2005. We incorporated possible confounders, including weather and long-term and seasonal mortality trends. RESULTS D...

In this paper, installment options on the underlying asset which evolves according to Black-Scholes model and pays constant dividend to its owner will be considered. Applying arbitrage pricing theory, the non-homogeneous parabolic partial differential equation governing the value of installment option is derived. Then, penalty method is used to value the European continuous installment call opt...

Wireless data services are fundamental in ubiquitous networks. In wireless data networks, the TCP congestion mechanism can mistake a wireless channel error or blackout for congestion on the route. Several wireless TCP protocols have been proposed considering TCP performance degradation in wireless systems. However, these protocols are too complex to deploy in wireless systems. In this paper, we...
