Summary: Ensemble simulation is an important method for handling uncertainties in numerical simulations, and visualization is a promising and powerful analysis method in this field. A new perspective using attribute variable dimension and variable spatial spreading for ensemble data analysis has been proposed, with an interactive framework designed to support uncertainty distribution perception, region selection, and temporal analysis effectively. Feedback from domain experts confirms the efficacy of the framework through analysis of a real-world ensemble simulation dataset.

Summary: A series of recent studies have focused on designing responsive multi-view visualizations, but there are still unresolved questions. This paper presents a framework for designing responsive multi-view visualizations for genomics data. Existing genomics visualization tools rarely support responsiveness. The paper identifies usability issues and discusses approaches to address them, as well as extending the Gosling visualization grammar to support responsive constructs. The study suggests considering different input modalities in future research.

Summary: The study presents a multimodal approach to quantify and visualize fiber orientation and resin-rich areas in carbon-fiber-reinforced polymers manufactured by vacuum infusion. The use of TLGI-XCT provides enhanced contrast between polymer matrix and carbon fibers at lower spatial resolutions, facilitating the assessment of resin-rich areas. The combination of DPC and DFC helps in quantifying resin-rich areas and understanding their distribution patterns within the composite material.

Summary: In this study, we use X-ray computed tomography (XCT) for in-line inspection of aluminum cylinder heads and apply and adapt the probability of detection (POD) methods. By using a simulation tool to generate virtual X-ray radiographs, the need for manufacturing specimens with known defect characteristics is eliminated. The virtual images are analyzed using an automated defect detection method to quantify defects. The hit/miss approach is used to create the defect curves. The results demonstrate the advantages of numerical simulations in quantifying and improving defect detection.

Summary: Inhomogeneous structure with central segregation occurs in commercial twin-roll cast AA 3003 aluminum alloy, where segregations form as manganese, iron, and silicon-rich channels spread in the rolling direction. Diffusion of silicon during annealing leads to the formation and growth of voids due to the Kirkendall effect.

Summary: A new framework is proposed for reconstructing curved fibres from X-ray computed tomography data of glass fibre-reinforced composites. It can detect fibres in a low-dose, low-resolution CT scan, and estimate their parameters directly from a few high-resolution 2D projection images. The framework is validated on both simulated and real data, showing robustness to noise and requiring less than 10 high-resolution projections for accurate estimates. It can also improve existing estimation frameworks based on full 3D scans.
