Purdue University engineers have developed a system that will enable employees to search huge industry databases of parts created with computer-aided design, or CAD, software, such as this image. Before a CAD part can be searched, its three-dimensional shape must be converted into "voxels," or volume elements, and then the system uses complex software algorithms to convert the voxels into a simplified "skeletal graph" based on "feature vectors," or numbers that represent a parts shape. The system then searches for these simplified skeletal graphs. (Purdue Research and Education Center for Information Systems in Engineering, School of Mechanical Engineering)
Here is another example of CAD parts contained in company databases. Purdue University engineers have developed a system that will enable employees to search huge industry databases for such parts.

Researchers at Purdue University have developed the first system capable of searching a company’s huge database of three-dimensional parts created with computer-aided design software.
Such "parts search engines" could save time and millions of dollars annually by making it easier for companies to "reuse" previous designs, benefiting from the lessons learned in creating past parts.
"Designers spend about 60 percent of their time searching for the right information, which is rated as the most frustrating of engineers’ activities," said Karthik Ramani, a professor of mechanical engineering and director of the Purdue Research and Education Center for Information Systems in Engineering. "The whole power of computers is lost if you are not able to retrieve and ’reuse’ what you have created in the past."

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).
The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
