When the distribution of lifetimes is 2-parameter exponential, Balasooriya [6] provided a failure-censored reliability sampling-plan to save test time. This paper extends the Balasooriya sampling plan to the Weibull distribution and provides a limited failure-censored reliability sampling plan (LFCR) to do life testing when test facilities are scarce. The -expected test time of the LFCR is comp...

This study presents a sub-Nyquist sampling model using compressed sensing (CS) as a new signal processing framework to acquire and reconstruct sparse signals. High-speed periodic signals were sampled using low frequency sampling circuit and reconstructed via CS recovery algorithm, resulting in a high equivalent sampling frequency. This prototype system is able to capture repetitive waveforms at...

Network frequency variations cause a dramatic performance decay in repetitive controller-based shunt active power filters. This problem may be solved by adapting the sampling period in order to keep the ratio between the network period and the sampling period at a constant value. However, these changes may yield closed-loop instability. The introduction of a precompensator that forces the plant...

Skip-lot sampling plans have been widely used in industries to reduce inspection efforts when products excellent quality records. This paper provides an economic model based on SkSP-2 with the double plan as a reference plan. The various combinations of producer level and consumer by minimizing both producer’s consumer’s risk discussed. Numerical examples are provided confirm application propos...

In the present study, a group-acceptance sampling plan was presented when lifetime of an item followed alpha power transformation-inverted perks distribution. The median is used as quality index to attain design parameters, such acceptance number and minimum group size, which are determined test termination consumer risk specified. operating characteristic values both graphically in form tables...

In this paper, a reliability acceptance plan is developed assuming that the lifetime of a product follows the generalized Rayleigh distribution with known value of the shape parameter. We obtain test termination ratio by considering the producer’s risk for given values of the sample size and the acceptance number. A comparison of proposed sampling plan has been made with an existing acceptance ...

In this paper, we develop a comprehensive framework forre-optimization of a large and useful set of queries, called repetitive queries. Repetitive queries refer tothosequeries that are likely to be used repeatedly or frequently in the future. Theydeserve more optimization efforts than ordinary ad hoc queries. In this research, weidentify statistics, called sufficient statistics,that are suffici...
