Acceptance sampling had become an essential practical tool for quality assurance application, closely related with incoming inspection. Acceptance sampling plans provide the decision rule for product acceptance to meet the preset product quality required by the vendor and the buyer. As today’s modern paradigm of quality improvement, reduction of variance from the target value is the guiding pri...

The area under the curve (AUC) can be associated with the therapeutic or toxic effect of a drug. The limited sampling model (LSM) is an approach that is gaining popularity due to its simplicity for the estimation of AUC using 1-3 blood samples. The aim of the present simulation study was to compare the performance of LSM for various hypothetical drugs with that of the naive trapezoidal method (...

Repetitive control (RC) scheme presents an attractive solution to achieve excellent steady-state tracking error and low total harmonic distortion (THD) for periodic signals. RC can produce extremely large gains at fundamental and each harmonic frequency of reference signal to achieve all harmonics suppression. However, a DC-AC inverter always has uneven THD distribution, e.g. THD concentrates a...

A sequence r1, r2, . . . , r2n such that ri = rn+i for all 1 ≤ i ≤ n, is called a repetition. A sequence S is called non-repetitive if no block (i.e. subsequence of consecutive terms of S) is a repetition. Let G be a graph whose edges are coloured. A trail is called non-repetitive if the sequence of colours of its edges is non-repetitive. If G is a plane graph, a facial non-repetitive edge-colo...

in this research, a new control policy for the acceptance sampling problem is introduced. decision is made based on the number of defectives items in an inspected batch. the objective of the model is to find a constant control level that minimizes the total costs, including the cost of rejecting the batch, the cost of inspection and the cost of defective items. the optimization is performed by ...

This study presents a compressed sensing (CS) based sampling approach for repetitive ultrasonic signal. Proposed system considers recovering ultrasonic signal with high equivalent sampling frequency from samples captured using analog-to-digital converter (ADC) clocked at a rate lower than Nyquist rate. A basis function is constructed to realize ultrasonic signal sparse representation, which pav...

OBJECTIVES Although antiretroviral therapy (ART) effectively suppresses HIV-1 replication, it does not eradicate the virus and ART interruption consistently results in rebound of viraemia, demonstrating the persistence of a long-lived viral reservoir. Several approaches aimed at reducing virus persistence are being developed, and accurate measurements of the latent reservoir (LR) are necessary ...

Fourteen commercial leek fields with first and second generation Leek moth, Acrolepiopsis assectella Z., (LM) injury were sampled during 1986 in The Netherlands. For both generations, plant injury was more prevalent in the perimeter of the field than in interior portions. A sequential sampling program for use in making treatment decisions for LM was developed. An economic analysis of the value ...

Control of critical dimension (CD) variation is of extreme importance in modern semiconductor manufacturing processes. To be controlled, the nature of CD variation must be understood. This paper outlines a method for characterizing systematic spatial variation by means of dense electrical linewidth measurements, including actual sample data. In addition, since exhaustive sampling is prohibitive...

J. Econ.Entomol.89(6): 1468-1476 (1996) ABSTRACT Sequential sampling plans were developed for use in recommending control of European corn borer, Ostrinia nubilalis (Hiibner), in potato, Solanum tuberosum L., fields based on the distribution of damaged stems. Likelihood ratio tests indicated that the betabinomial distribution (aggregated) provided a better fit than the binomial (random) when th...
