Abstract In conventional sampling plans, the rate of fraction faulty items is supposed and fixed, but in some practical situations, this value not fixed fuzzy. To attain real flexible value, we used transmuted Weibull distribution a fuzzy environment. Fuzzy based on set theory. According to our investigation, acceptance The improvement research evaluate vague portion malfunctioning ( $$\tilde{p...

OBJECTIVE: To describe the sampling plan and estimation methods used to collect and analyze data in the survey Sexual Behavior and Perceptions of the Brazilian Population concerning HIV/Aids in 2005. METHODS: The study presents the decisions that were made concerning population defi nition, strata of interest to the survey and to the sampling plan, main procedures for data analysis and sample p...

CIRCA is an architecture for real-time intelligent control. The CIRCA planner can generate plans that are guaranteed to maintain system safety, given certain timing constraints. To prove that its plans guarantee safety, CIRCA relies on formal verification methods. However, in many domains it is impossible to build 100% guaranteed safe plans, either because it requires more resources than availa...

Objective: Some theories state that a deficiency in cognitive control makes people more vulnerable to the occurrence of repetitive negative thoughts. The present study was done to investigate the association between cognitive control based on switching and inhibition and repetitive thinking of rumination and worry and major depressive disorder and generalized anxiety disorder. Methods: Thirty ...

The sampling plan for the mean for correlated data is studied. The Operating Characteristic (OC) of the variable sampling plan for mean for correlated data are calculated and compared with the OC of known σ case.
