EPFL researchers have developed a numerical model that can re-create the state of Switzerland's Rhône Glacier as it was in 1874 and predict its evolution until the year 2100. This is the longest period of time ever modeled in the life of a glacier, involving complex data analysis and mathematical techniques. The work will serve as a benchmark study for those interested in the state of glaciers and their relation to climate change. The Laboratory of Hydraulics, Hydrology and...

Supercomputers simulate products and manufacturing processes with-in minutes. In the Computer Aided Robust Design CAROD project, Fraunhofer researchers are developing new methods and software that significantly improve the quality of the virtual components. Trucks drive thousands of kilometers through Europe every month, taking oranges from Greece to Scandinavia, delivering Spanish vegetables to German wholesalers, and collecting milk from farms in the region to take it to central dairies. To...

With the aid of computerized image analysis, it may be possible in the future for radiologists to feel images with the help of a three-dimensional mouse. Erik Vidholm at Uppsala University has been involved in developing the new technology, which makes it easier to diagnose and plan the treatment of cancer, for instance. Computerized image analysis can be used to determine the size of organs like the liver, or to construct three-dimensional models of organs when surgery or radiation is being...

ORLANDO, Fla. -- A loud boy launches spit balls at a classmate. Another kid slumps in his seat, oozing apathy and his desire to be anywhere else. Other students laugh mockingly and make inappropriate sounds as the rookie teacher faces his worst classroom nightmare. It's no easy job to regain control and coax the students into writing an essay about what they did last weekend. Fortunately for the teacher, it was only a computer simulation. The children are a mix of virtual humans projected on...

Making good business and production decisions isn't as straightforward or intuitive as it used to be because today's global market and business environment is exceedingly more complex. "When Henry Ford started making Model Ts, the goal was mass production. "He wanted to stamp out thousands of the same thing and didn't have to change the basic setup once it worked," says Young-Jun Son, an assistant professor in Systems and Industrial Engineering (SIE) at The University of Arizona. "In that...

The San Francisco Bay region has a 25 percent chance of a magnitude 7 or greater earthquake in the next 20 years, and a roughly 1 percent chance of such an earthquake each year, according to the "Virtual California" computer simulation. The Virtual California approach to earthquake forecasting is similar to the computer models used for weather forecasting, said John Rundle, director of the UC Davis Computational Science and Engineering Center, who has developed the model with colleagues from...

COLUMBUS, Ohio -- Oil companies could soon harness the power of distant supercomputers to tackle problems such as where to place equipment and how to clean up oil spills. For decades, the industry has used computers to maximize profit and minimize environmental impact, explained Tahsin Kurc, assistant professor of biomedical informatics at Ohio State University. Typically, companies take seismic measurements of an oil reservoir and simulate drilling scenarios on a local computer. Now...

Large-scale computer simulations have pinpointed a tiny change in molecular structure that could account for drug resistance in Streptomices pneumoniae, the organism that causes childhood pneumonia and claims 3.5 million lives a year, mainly in developing countries. Such knowledge could be invaluable in designing new drugs that are effective against the drug resistant strain. Experiments to find out how changes at the molecular level are causing this resistance are difficult and, so far,...

Scientists at the University of Chicago and Argonne National Laboratory have constructed a computer simulation that allows them to study the relationship between biochemical fluctuations within a single cell and the cell's behavior as it interacts with other cells and its environment. The simulation, called AgentCell, has possible applications in cancer research, drug development and combating bioterrorism. Other simulations of biological systems are limited to the molecular level, the...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
