A team of Dartmouth researchers has developed a new computational tool to help authenticate works of art, specifically paintings, prints and drawings.
Using high resolution digital images of drawings by Bruegel and some of his imitators, as well as a painting by Perugino, the computer scientists captured data about pen or pencil stroke patterns and other elements that represent an artist’s style or aesthetic signature. This signature was then used to discover consistencies and inconsistencies within a single piece of artwork or among works by the same artist. The study was published in the Proceedings of the National Academy of Sciences (PNAS) Online Early Edition during the week of Nov. 22-26, 2004.
"Similar methods have been used to analyze works of literature, like assigning authorship of different parts of The Federalist Papers to Alexander Hamilton and James Madison," says Hany Farid, Associate Professor of Computer Science and an author on the paper. "We can find things in art work that are unique to the artist, like the subtle choice of words or phrasing and cadence that are characteristic of a certain writer."

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
