Secondary data sources can provide valuable information about environmental releases during chemical manufacturing. However, the often facility-level nature of the data challenges their utility for modeling specific processes and can impact the quality of the resulting inventory. First, a thorough data ...
the consumer's risk is too big.Two improved plans were given.Converting subsystem test data into system test data,the second sampling plan is replaced with a third sampling plan;Bayes sampling plan with test data of s...
Furthermore, our secondary endpoints were the predictive values of PET/CT, MRI, and combined PET/CT and MRI to predict ALN burden in five groups, including patients with 0, 1, 2, 1–2 (low burden), and 0–2 (indicator for SLNB) [7] positive ALNs on imaging. These predictive values...
Time required for dynamically migrating services from the faulty standby or secondary node in a cluster NOTE: In this scenario, performance data in some periods is lost due to service migration. The service migration efficiency is 20,000 collection units per minute. A small number of alarms rep...
By statistical analysis to a large number of data collected from the reliability test of 120km/h raising speed wagon,this paper,based on the theory of reliability engineering,elaborated the reliability of the tested wagon in the field of running safety,maintenance support,failure mode effect and ...
an no data of any kind is replicated to another region by Microsoft. While this failover option requires a bit more effort, it enables faster failover, and you are in control of choosing secondary regions. If you want to implement client-side disaster recovery for Azure Event Grid topics, ...
AnalyticDB for PostgreSQL also uses the triplicate storage technology of disks to ensure data reliability. The system switches over to a secondary node when the primary node fails and recovers a node when the node fails. This ensures high availability. You can also restore data by using the ...
For a significance level of 0.05 and a power of 80%, the required sample size is 55 subjects. We add an additional 5 subjects to account for potential dropouts, missing data, or issues during data collection. For the secondary analysis, a sample size of 55 subjects allows us to detect a...
The invention discloses a power supply reliability-oriented secondary optimization evaluation model for the reliability of a power distribution network. The evaluation model comprises a smallest isolation area sub-model, a failing area influence sub-model and a load area statistical sub-model, wherein...
