The research hypothesis of this study revolves around employing Multi-Criteria Decision Analysis (MCDA) techniques, particularly the Analytical Hierarchical Process (AHP), to optimize technology selection in metal additive manufacturing. The data collected and analyzed includes the results of the survey and criteria evaluation relevant to the decision-making process, such as reliability, finishing of the part after printing, complexity of post-processing, sustainability of the process, user preferences, machine price, manufacturing cost, and productivity. The AHP methodology involves constructing a hierarchy structure wherein the goal or objective, criteria, and alternatives are systematically organized. Pairwise comparisons are then made among criteria and alternatives, using a relative importance scale ranging from 1 to 9. These comparisons are recorded in a positive reciprocal matrix, which is then normalized to obtain numerical weights for decision-making. The priority vector or normalized principal eigenvector is computed, representing the relative importance of criteria, and the maximum eigenvalue is determined. Finally, a global ranking of decision alternatives is analyzed based on additive aggregation and normalization of the sum of local priorities of criteria and alternatives.

Background Microarray experiments offer a potent solution to the problem of making and comparing large numbers of gene expression measurements either in different cell types or in the same cell type under different conditions. Inferences about the biological relevance of observed changes in expression depend on the statistical significance of the changes. In lieu of many replicates with which to determine accurate intensity means and variances, reliable estimates of statistical significance remain problematic. Without such estimates, overly conservative choices for significance must be enforced. Results A simple statistical method for estimating variances from microarray control data which does not require multiple replicates is presented. Comparison of datasets from two commercial entities using this difference-averaging method demonstrates that the standard deviation of the signal scales at a level intermediate between the signal intensity and its square root. Application of the method to a dataset related to the β-catenin pathway yields a larger number of biologically reasonable genes whose expression is altered than the ratio method. Conclusions The difference-averaging method enables determination of variances as a function of signal intensities by averaging over the entire dataset. The method also provides a platform-independent view of important statistical properties of microarray data.

The Everyday Itinerary Dataset is the first public-use dataset in the Dunham's Data series, a unique data collection created by Kate Elswit (Royal Central School of Speech and Drama, University of London) and Harmony Bench (The Ohio State University) to explore questions and problems that make the analysis and visualization of data meaningful for dance history through the case study of choreographer Katherine Dunham. It is a manually curated dataset of Katherine Dunham's touring from 1937-1962, encompassing Dunham's daily locations, travel, and performances. This dataset tracks geographic location and, less comprehensively, the accommodation in which Dunham stayed each night; the theatres, nightclubs, television studios, and other places where she and the company performed; the modes of transportation used when travel occurred; additional transit cities through which she passed; and whether or not Dunham was likely to be in rehearsals or giving public performances. Dunham's Data: Digital Methods for Dance Historical Inquiry is funded by the United Kingdom Arts and Humanities Research Council (AHRC AH/R012989/1, 2018-2022) and is part of a larger suite of ongoing digital collaborations by Bench and Elswit, Movement on the Move. The Dunham's Data team also includes digital humanities postdoctoral research assistant Antonio Jiménez-Mavillard and dance history postdoctoral research assistants Takiyah Nur Amin and Tia-Monique Uzor.
