Abstract With projected temperature increases and extreme events due to climate change for many regions of the world, characterizing impacts these emerging hazards on water distribution systems is necessary identify prioritize adaptation strategies ensuring reliability. To aid decision-making, new insights are needed into how system reliability climate-driven heat will change, proactive mainten...
Center for Wireless Communications, University of California San Diego 9500 Gilman Drive – La Jolla, CA 92093-0407, USA – fax: +1-619-534-2486 e-mail: [email protected] – http://www-cwc.ucsd.edu/~zorzi Abstract— In this paper, we present an analytical framework for the computation of the outage probability, the outage duration and the frequency of outage. A Markov description is assumed for th...
Determining whether power outages have significant fertility effects is an important policy question in developing countries, where blackouts are common and modern forms of family planning are scarce. Using birth records from Zanzibar, this study shows that a month-long blackout in 2008 caused a significant increase in the number of births 8 to 10 months later. The increase was similar across v...
Dynamic, mobile platforms offer the opportunity to analyze robustness to satellite outages due to aircraft maneuvers or other real-world situations where interruptions in continuity, in particular, can potentially be problematic. And real-time implementation serves to demonstrate the state of readiness of the algorithm to meet its intended purpose—providing high-integrity navigation for aircraf...
Nuclear power plants must be regularly shut down in order to perform refueling and maintenance operations. The scheduling of the outages is the first problem to be solved in electricity production management. It is a hard combinatorial problem for which an exact solving is impossible. Our approach consists in modelling the problem by a two-level problem. First, we fix a feasible schedule of the...
