Thermoplastic Polymer Shrinkage in Emerging Molding Processes
In this paper, in situ experiments have been designed using the full-field deformation technique of Digital Image Correlation (DIC) to characterize non-uniform shrinkage in thermoplastic polymers commonly used in traditional and emerging molding processes. These experiments are capable of characterizing the differences in strains that develop due to thermal gradients and stiction as the polymer...
متن کاملOptimal Offline Compensation of Shape Shrinkage for 3D Printing Processes
Dimensional accuracy is a key control issue in direct 3D printing. Part shrinkage due to material phase changes often leads to final shape deviations, requiring extra postmachining steps for correction. Shrinkage has traditionally been analyzed through finite element simulation and experimental investigations. Systematic models for accuracy control through shrinkage compensation are hardly avai...
متن کاملLocal Shrinkage Rules, Lévy Processes, and Regularized Regression
We use Lévy processes to generate joint prior distributions, and therefore penalty functions, for a location parameter β = (β1, . . . ,βp) as p grows large. This generalizes the class of local-global shrinkage rules based on scale mixtures of normals, illuminates new connections among disparate methods, and leads to new results for computing posterior means and modes under a wide class of prior...
متن کاملHierarchical Shrinkage Priors for Dynamic Regressions With Many Predictors
This paper builds on a simple unified representation of shrinkage Bayes estimators based on hierarchical Normal-Gamma priors. Various popular penalized least squares estimators for shrinkage and selection in regression models can be recovered using this single hierarchical Bayes formulation. Using 129 U.S. macroeconomic quarterly variables for the period 1959 – 2010 I exhaustively evaluate the ...
متن کاملBayesian shrinkage analysis of quantitative trait Loci for dynamic traits.
Many quantitative traits are measured repeatedly during the life of an organism. Such traits are called dynamic traits. The pattern of the changes of a dynamic trait is called the growth trajectory. Studying the growth trajectory may enhance our understanding of the genetic architecture of the growth trajectory. Recently, we developed an interval-mapping procedure to map QTL for dynamic traits ...
