Our objective was to review the
failure rates of varicocele embolization done for male factor infertility at the University of Toronto, Toronto, Ontario, and to examine how these rates compare with those published for varicocele embolization and surgical varicocele repair.
to conduct new safety studies, and prior to that the ASR all-metal hip was recalled by its manufacturer because of high
failure rates.
There was a slightly lower
failure rate for those residents with step 1 USMLE 2-digit scores of 81 to 89; however, US graduates at UPMC had the greatest
failure rates (35.7%; 5 of 14) compared with other resident groups, especially international medical graduates (16.7%; 3 of 18).
For a stage of early failures, it is first necessary to choose a kind of the dependence describing change of mean value of a
failure rate (further--failure rate) of devices in the course time.
The coefficient of determination is 0.51, so that the model explains one-half of the variation in the bank
failure rate. The DW of 2.04 implies the absence of autocorrelation problems.
Table 4 reports correlations of the number of bank failures and the two
failure rate measures with various measures of state-level economic conditions.
Therefore the sensitivity of the yearly mean time to failure to the
failure rates of equipments for SEVEE was not presented in the paper.
For the exponential model, the mean time to failure and standard deviation are readily shown to be the reciprocal of the
failure rate, r (Raheja).
This method defines the failure distribution, failure effect, safe mode, detectability, detection method, and diagnostic coverage (DC), as well as the
failure rate of the components.
The report also disclosed that over half (52 percent) of payment providers experience payment
failure rates of less than one percent, and almost all respondents (90 percent) cite a payments
failure rate under five percent.
The company also points out that Samsung's devices most often submitted for repairs and have a
failure rate of 27.4 percent, followed by Xiaomi with 14.2 percent.
It looks into the individual data points of the most recent data collection to identify more than common statistical averages, such as mean time between failures (MTBF), mean time to maintain (MTTM),
failure rate, and others; the information presented here shows how
failure rates have changed over time, how confidence intervals indicate quality of information, how preventative maintenance actions positively and negatively influence the frequency of failure events, and how
failure rates change as a function of equipment age.
