This paper presents the results of a study using a simple model to investigate the impacts of basic architecture characteristics on the spread of failures through a system-of-system after an initial failure occurs.
Buzna et al. (2006) proposed a synthetic model to simulate the dynamic spreading of failures in networked systems and analyzed the system properties under different circumstances.
Every day 50% of its registered users log in at least once – and as news spread of its failure, more and more tried to log in, making the problem worse.
Adepts uses a directed graph representation to model the spread of the failure through the system, presents algorithms for determining appropriate responses and monitoring their effectiveness, and quantifies the effect of disruptions through a high level survivability metric.
In the meantime, measures that may forestall the emergence and spread of DP failures along the China Myanmar border include vector avoidance and control measures, proper dosing of DP in children (who clear piperaquine more rapidly than adults), and the use of primaquine to prevent transmission.
Taken any more seriously than that, box office pre-release punditry can be a dangerous tool for one studio to spread a narrative of failure based on nothing more than a random prediction.
This was, let's face it, not so much a tactical blunder as a systemic collapse, a story of failure spreading back up the arm.
Fair or not, once the reputation of failure spreads into consumers' psyches, it can be difficult to overcome, though hexes are broken all the time since the public's memory can be fickle.
As the United States and Canadian governments put it in November in their report on the blackout, these relays helped spread a "cascade" of failures, reducing "the potential time in which grid operators might have identified the growing problem and acted constructively to contain it".
6, 9– 12 With a 5-year distant relapse rate of 30 40%, the occurrence of systemic metastatic spread remains the predominant mode of failure and limits long-term prognosis.
The wildfire spread of violence, the initial failure of the police to contain it, the slow early response of political leaders and the cruelty of the attacks have left the nation shaken and wrung by an embittered debate about whom and what to blame.
