This framework provides scalable land use characterization using Points of Interest (POIs) and non-POI geographic features. Leveraging open-access POI data and hierarchical spatial structures, it generates high-dimensional embeddings that capture spatial and semantic characteristics of land use for areas of interest (AOIs). An OSM-tag-based representation harmonizes diverse data sources, while a neural network language model produces embeddings optimized for multi-scale land use classification across geographic regions. Supervised classification models validate the robustness of AOI embeddings, revealing variations in semantic salience for different land use types. Results demonstrate that combining POIs with non-POI features and tailoring spatial and semantic granularities enhance land use characterization. Future directions include augmenting data and integrating temporal dynamics to improve representational accuracy and capture land use patterns more effectively.

The shells have perforations passing through their inner and outer surfaces. The shells include therein perforated coolant distributor elements coupled to or unitary with the inner surfaces. Each perforated element is in line with a respective shell perforation, which allows coolant to flow into the sphere through the perforations and elements. When bombarded by neutrons, the nested pebbles produce fusion fuel to sustain fusion reactions. The coolant sweeps out the fusion fuel, and cools the breeding spheroids. Pebbles in the blanket are replenished with conveyor systems. A separator extracts the fusion fuel from the blanket coolant. Heat from the walls and the nested pebble bed is extracted by inert gases and then conveyed to a thermal storage and/or a power cycle.

Modern retrofit construction practices use 3D point cloud data of the building envelope to obtain the as-built dimensions. However, manual segmentation by a trained professional is required to identify and measure window openings, door openings, and other architectural features, making the use of 3D point clouds labor-intensive. Automatic point Cloud Building Envelope Segmentation (Auto-CuBES) algorithms can significantly reduce the time spent during point cloud segmentation. The Auto-CuBES algorithm inputs a 3D point cloud generated by commonly available surveying equipment and outputs a dimensioned wire-frame model of the building envelope. By leveraging unsupervised machine learning methods in the Auto-CuBES methods facades, windows, and doors can be identified while keeping the number of calibration parameters low. Additionally, some embodiments of Auto-CuBES can generate a heat map of each facade indicating nonplanar characteristics that are valuable for optimization of connections used in overclad envelope retrofits.

A method for friction pressure welding a top workpiece to a bottom workpiece is provided. The method includes plunging a non-consumable refractory tool into the top workpiece with axial plunge pressure and rotational motion. The friction heat generated by the interaction between the tool and the top workpiece diffuses into the faying joint interface and into the bottom workpiece. Friction heat and applied axial plunge pressure promote diffusion bonding at the faying joint interface, which consolidates as a solid-state weld. This inventive method is suitable for spot welding or continuous linear welding, and each workpiece can be comprised of similar or dissimilar materials.
