Negligence without Fault

Fault lines: resolving clinical negligence claims.

The cost of clinical negligence claims against the NHS in England rose to £1.259bn ($1.9bn, €1.5bn) in the last financial year, and the number of new cases in 2012-13 climbed by 10.8% to more than 10 000. The year before, in 2011-12, the bill breached £1bn for the first time after a 30% rise in claims the previous year, forcing the UK government to pump in an emergency cash injection. The figur...

Fault Location on Compensated Transmission Lines without Current Measurement

This paper presents a novel fault location method for series compensated transmission lines. It is established based on synchronized voltages sampling and Thevenin impedance from both ends of series compensated transmission line. The method is based on the use of phasor measurement units (PMU) technology which is aimed to be independent of current measurements, fault type, fault resistance, fau...

Fault-tolerant Computation without Concatenation

It has been known that error-correction via concatenated codes can be done with exponentially small failure rate if the error rate for physical qubits is below a certain accuracy threshold (probably ∼ 10–10). Other, un-concatenated codes with their own attractive features—e.g., an accuracy threshold ∼ 10—have also been studied. A method to obtain universal computation is presented here which do...

Diagnosability Analysis without Fault Models

This paper addresses the problem of diagnosability analysis, which allows a system designer to anticipate the performance of a model based diagnosis (MBD) algorithm for a given system. Such analysis requires a formal description of the system behavior, called model, which can be very difficult to establish, especially when faults occur in the system. Despite this, all known diagnosability frame...
