In the world of database architecture, the need to dynamically create complex objects conflicts with the demand for subsecond response time. Oracle's answer to this dilemma is the materialized view.

Improvements in three-dimensional (3D) scanning have enabled quick and accurate scanning of 3D objects, including cultural heritage objects, as 3D point cloud data. However, conventional ...

Trees and other plants lead the way: they produce cellulose themselves and use it to build complex structures with extraordinary mechanical properties. That makes cellulose attractive to materials ...

3D printing is super cool, but it's also super slow -- it would take 115 days to print a detailed, multimaterial object about the size of a grapefruit. A new method allows printing with up to 8 ...

The object scale of a small object scene changes greatly, and the object is easily disturbed by a complex background. Generic object detectors do not perform well on small object detection tasks. In ...

Researchers from ETH Zurich and the Swiss Federal Laboratories for Materials Science and Technology (Empa) have set a new world record: they 3-D printed complex objects with higher cellulose content ...

(Nanowerk News) Researchers from ETH Zurich and the Swiss Federal Laboratories for Materials Science and Technology (Empa) have set a new world record: they 3D printed complex objects with higher ...

The proposed technique employs two novel approaches: dual 3D edge extraction and opacity–color gradation, to enhance the clarity of 3D scanned objects. Recent advances in three-dimensional (3D) ...

Taking advantage of molecules that switch states when exposed to particular wavelengths of light, researchers have developed a 3-D printing method that can make precise objects in a matter of minutes.

Complex field imaging, which captures both the amplitude and phase information of input optical fields or objects, can offer rich structural insights into samples, such as their absorption and ...

Imaging buried objects Left: artistic impression of metal spheres buried in small glass beads; centre: conventional ultrasound image; right: the new technology can precisely determine the positions of ...
