Shortly after 9.30pm on 13 July, in the middle of a heatwave, a series of errors and malfunctions caused all of the city's generators to shut down.
But federal records show that many serious episodes are caused by factors for which utilities are responsible, including pipeline corrosion, operator errors and malfunctioning equipment.
For example, efficiency could be expressed in terms of minimizing costs for diffusing information [59, 60], robustness could be represented by the presence of redundant connections that link the same groups and reliability by the ability of the network to well-react to errors and malfunctioning [61 63].
Some interviewees felt that adequate training by the hospital and manufacturers on the use of a current or new medical device for new staff and continuous education on how to operate a medical device would help the end-user to understand the medical device functionality and to recognize potential errors and malfunctions associated when used on a patient.
And there are the "risk-assessment" studies that find nuclear power quite safe in statistical terms, failing as these studies do to account for extreme events of nature as well as human error and technical malfunction.
The input uncertainties associated with the observer error and the malfunctioning of the input devices are modeled by interval type-2 fuzzy MFs instead of crisp numbers.
Through the constructing of the residual generator, the FD design scheme is converted to an H ∞ filtering problem in order that the error between residual and malfunction is minimized at the H ∞ level.
From its start on Oct. 7, the campaign has been marked by targeting mistakes, pilot errors and equipment malfunctions that have caused civilian deaths, though the Pentagon has said the mistakes have been far fewer, with fewer casualties, than the Taliban have alleged.
Both teams later complained about officiating errors and the malfunctioning game clock.
Gross errors are outliers (process leaks and malfunction) or bias (systematical offset).
