Computation of optimum reliability acceptance sampling plans in presence of hybrid censoring

The decision regarding acceptance or rejection of a lot of products may be considered through variables acceptance sampling plans based on suitable quality characteristics. A variables sampling plan to determine the acceptability of a lot of products based on the lifetime of the products is called reliability acceptance sampling plan (RASP). This work considers the determination of optimum RASP under cost constraint in the framework of hybrid censoring. Weibull lifetime models are considered for illustrations; however, the proposed methodology can be easily extended to any location-scale family of distributions. The proposed method is based on asymptotic results of the estimators of parameters of lifetime distribution. Hence, a Monte Carlo simulation study is conducted in order to show that the sampling plans meet the specified risks for finite sample size.     

Paint Mesh Cutting

We present a novel progressive painting‐based mesh cut out tool, called Paint Mesh Cutting, for interactive mesh segmentation. Different from the previous user interfaces, the user only needs to draw a single stroke on the foreground region and then obtains the desired cutting part at an interactive rate. Moreover, the user progressively paints the region of interest using a brush and has the instant feedback on cutting results as he/she drags the mouse. This is achieved by efficient local graph‐cut based optimizations based on the Gaussian mixture models (GMM) on the shape diameter function (SDF) metric of the shape. We demonstrate a number of various examples to illustrate the flexibility and applicability of our system and present a user study that supports the advantages of our user interface.

Construction and evaluation of a three-dimensional structure of cytochrome P450choP enzyme (CYP105C1)

The purpose of this work was to develop and carefully evaluateimproved strategies for constructing reliable 3-D models ofP450 isozymes. To this end, a unique combination of steps forbuilding and evaluating a model structure was used to builda homology model of the P450choP isozyme, based on knowledgeof the X-ray structures of P450cam, P450terp, P450BM-3 and P450eryF.Specifically, the reliability of this model was examined bysystematic comparisons of its conformational, energetic, environmentaland packing properties and those of the four reference proteinswith corresponding properties from the database of proteinswith known structures. The results showed that the examinedproperties of this model structure are well within the criteriaestablished for reliable structures and are of nearly as goodquality as those of the reference proteins. In addition, theresult from a 120 ps unconstrained MD simulation of the modelwith structural waters provided evidence that the model is stableat room temperature. This 3-D model can now be reliably usedfor explicit characterization of substrate and inhibitor complexes.Most importantly, although it is envisioned that building modelsfor mammalian P450s will be even more challenging, the stepsdescribed here should be very useful in future constructionof 3-D models of mammalian P450 isozymes.
