In this research, a new acceptance sampling plan for a truncated life test is presented, assuming that the quality characteristic follows the power Lomax distribution. The operating characteristic function values are calculated for the proposed sampling plan, jointly with the optimal sample size and the producer’s risk for a selection of distribution parameters. Furthermore, a comparative study with other sampling plans is introduced to demonstrate the advantages of the proposed plan

In this manuscript, a group acceptance sampling plan (GASP) is developed when the lifetime of the items follows odd generalized exponential log-logistic distribution (OGELLD), the multiple number of items as a group can be tested simultaneously in a tester. The design parameters such as the minimum group size and the acceptance number are derived when the consumer’s risk and the test termination time are specified. The operating characteristic (OC) function values are calculated (intended

This paper has given the structure, operating principle, and force analysis of electric power steering (EPS) system aimed at a type of forklift. Combing with forklift operating characteristic, three variable power characteristics curve based on steering wheel torque, real-time speed, and load is designed, so is the three dimensional diagram of forklift power gradient by using fuzzy rule. The dynamic model of EPS system and two-degree-of-freedom linear model of forklift dynamics are established

. Categorical variables were tested by Fisher’s exact test. The Mann-Whitney U test was used for the comparison of stiffness, velocity and VI values between pleomorphic adenomas and Warthin tumors. The Spearman correlation analysis was used to evaluate the relationship between the VI values, the lesion area in mm2, and stiffness and velocity values. The statistical significance level was defined as 0.05. A receiver operating characteristic (ROC) curve analysis was performed to determine the best cut-off

Approximation (RMSEA). Satorra-Bentler correction for χ2 was used regardless non-normality of the data.
The Receiver-Operating Characteristic (ROC) was performed to obtain specificity, sensitivity and cut-off point. The ROC analysis was obtained by comparing the NDDI-E scores between those with and without depression based on the MINI items. Between group differences in NDDI-E score were also examined and were used as indication of validity of NDDI-E. Considering the non-normal distribution of the NNDI-E

-wave elastography were compared with biopsy and histological results. Results: The comparison between the results of shear-wave elastography and those of biopsy was performed by receiver operating characteristic analysis, which suggested an optimum cut-off tissue elasticity value of 50 kPa, in agreement with earlier studies aimed at distinguishing between benign and malignant tissue. However, the diagnostic selectivity (and thus the diagnostic power) was poor (area under the curve 0.527, which

(for expected counts < 5) for binary outcomes and Wilcoxon rank-sum test for ordinal outcomes. Next, we calculated conditional probabilities for each of the studies separately using a conservative cut-off point of ≥ 180 for the CBCL-BP profile. We subsequently combined the data from the four studies and used receiver operating characteristic (ROC) curves to examine the ability of the CBCL-BP profile to identify those with and without a structured interview diagnosis of BP-I disorder.
