Characterization of the Fiber Orientations in Non-Crimp Glass Fiber Reinforced Composites using Structure Tensor

This dataset contains data, notebooks and code used in the publication: [1] Jeppesen, N., V.A. Dahl, A.N. Christensen, A.B. Dahl, L.P. Mikkelsen, Characterization of the fiber orientations in non-crimp glass fiber reinforced composites using structure tensor. <em>IOP Conf. Ser.: Mater. Sci. Eng.</em> <strong>942</strong>, 012037, https://doi.org/10.1088/1757-899X/942/1/012037, 2020 If you reference this dataset, please also consider referencing the paper above. HF401TT-13_FoV16.5_Stitch.zip contains an X-ray CT scan of a non-crimp glass fiber composite sample saved in the TXM file format. HF401TT-13_FoV16.5_Stitch.txm.nii contains a cut-out of the TXM data, where air around the sample has been removed and the result has been saved in the NIfTI file format. The two notebooks, <em>StructureTensorFiberAnalysisDemo</em> and <em>StructureTensorFiberAnalysisAdvancedDemo</em> rely on the NIfTI scan data, HF401TT-13_FoV16.5_Stitch.txm.nii. They demonstrate how to do structure tensor orientation analysis on the data. The HF401TT-13_FoV16.5_Stitch notebook use the TXM scan data, HF401TT-13_FoV16.5_Stitch.zip. It can be used to recreate the results of the published experimental results. To run the notebooks, the Python file, structure_tensor_workers.py, must be in the same directory as the notebook. By default, the notebooks expect the following folder structure: /notebooks: Folder with the notebooks and Python files.<br> /originals: Folder with the data (TXM/NIfTI files).<br> /tmp: Folder for temporary files and output generated running the notebooks.<br> /notebooks/figures: Folder for exporting figures as files (only needed if you want to save figures as files).本数据集包含发表文献[1]中使用的实验数据、代码与Notebook脚本： [1] Jeppesen, N., V.A. Dahl, A.N. Christensen, A.B. Dahl, L.P. Mikkelsen. 利用结构张量（structure tensor）表征非卷曲玻璃纤维增强复合材料的纤维取向[J]. *IOP会议系列：材料科学与工程（IOP Conf. Ser.: Mater. Sci. Eng.）*, **942**, 012037, 2020. https://doi.org/10.1088/1757-899X/942/1/012037 若引用本数据集，请同时引用上述发表文献。 `HF401TT-13_FoV16.5_Stitch.zip` 为采用TXM文件格式存储的非卷曲玻璃纤维复合材料样品的X射线计算机断层扫描（X-ray CT）扫描数据。 `HF401TT-13_FoV16.5_Stitch.txm.nii` 为该TXM扫描数据的裁剪子集，已移除样品周围的空气背景，并以NIfTI文件格式存储。 两款Notebook脚本，分别为*StructureTensorFiberAnalysisDemo*与*StructureTensorFiberAnalysisAdvancedDemo*，以`HF401TT-13_FoV16.5_Stitch.txm.nii`的NIfTI扫描数据为输入，演示如何对该数据开展结构张量取向分析。另有一款名为`HF401TT-13_FoV16.5_Stitch`的Notebook脚本，以`HF401TT-13_FoV16.5_Stitch.zip`中的TXM扫描数据为输入，可用于复现该发表文献中的实验结果。 若要运行上述Notebook脚本，需将Python文件`structure_tensor_workers.py`放置在与Notebook脚本相同的目录下。默认情况下，Notebook脚本预期的目录结构如下： - `/notebooks`：存储Notebook脚本与Python文件的目录 - `/originals`：存储原始数据（TXM与NIfTI文件）的目录 - `/tmp`：存储运行Notebook脚本时生成的临时文件与输出结果的目录 - `/notebooks/figures`：用于将生成的图片导出为文件的目录（仅当需要将图片保存为文件时需要）
