During the forming process, sheet metal materials are often stressed to their limits. Computer simulations are used to test how far it is possible to go in production. However, the simulation is only ever as exact as the data on which it is based. Scientists have now developed a virtual test laboratory that allows them to examine different load states for metal materials and determine precise mechanical data.
Researchers used computer modeling to show how cells can feel their way through their surroundings, for example, when a tumor cell invades a new tissue or organ.
A new software system helps robots to more effectively act on instructions from people, who by nature give commands that range from simple and straightforward to those that are more complex and imply a myriad of subtasks.
A new AI tool can create realistic videos from audio files alone -- including speeches by President Obama.
Researchers asked people why they use Facebook, then identified four categories of users.
A ground-breaking new study challenges the assumption that moral decisions are strongly context dependent and cannot be modeled or described algorithmically, finding that human behavior in dilemma situations can be modeled by a simple value-of-life-based model. The research suggests that human moral behavior can be well-described by algorithms and used by machines to manage moral dilemmas on the road.
Whether it's for computer games, motion analysis in sports, or even medical examinations, many applications require that people and their movements are captured digitally in 3D in real-time. Until now, this was possible only with expensive systems of several cameras, or by having people wear special suits. Computer scientists have now developed a system that requires only a single video camera. It can even estimate the 3D pose of a person acting in a pre-recorded video, for instance a YouTube video.
Paris' Cathedral of Notre Dame has a ghost orchestra that is always performing, thanks to a sophisticated, multidisciplinary acoustics research. In the project, computer models use recordings from a live concert held at the cathedral and detailed room acoustic simulations to produce a novel type of audience experience: a virtual recreation of the live performance using spatial audio and virtual reality.
A proposed tax on systemically risky financial transactions could reduce the risk of financial system crashes by spurring financial networks to reshape in more resilient ways, suggests a new report.
A new type of 3-D display could solve the long-standing problem eye fatigue when using VR and AR equipment by greatly improving the viewing comfort of these wearable devices.
Scientists have established 'Cosmowebportal', a unique data center for cosmological simulations. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
A mixed reality system that allows medical practitioners to view and interact with virtual replicas of patients' organs, bones or body parts is being developed by academics.
Imagine walking along a beach on a lovely day. As you turn to continue along the coast path feeling calm and relaxed you suddenly hear your dentist say 'Fine, all done, you can take the headset off now'. For patients at one dental practice in Devon, England, such Virtual Reality encounters are resulting in demonstrably better experiences in the dentist's chair.
Using a sophisticated type of mathematics in a way that it has never been used before in neuroscience, a scientists have uncovered a universe of multi-dimensional geometrical structures and spaces within the networks of the brain. This research has significant implications for our understanding of the brain.
Researchers have simulated the formation of our entire Universe with a large supercomputer. A gigantic catalogue of about 25 billion virtual galaxies has been generated from 2 trillion digital particles. This catalogue is being used to calibrate the experiments on board the Euclid satellite, that will be launched in 2020 with the objective of investigating the nature of dark matter and dark energy.
Researchers have studied how reacting with a smile affects game outcomes, hoping one day to empower virtual humans with this knowledge.
A new system that learns how to grasp objects has been developed by a team of researchers.
Researchers are able to use the radiosensitivity index within a mathematical framework to select the optimum radiotherapy dose for each patient based on their individual tumor biology, outlines a new report.
Virtual Reality (VR) can relieve the sensation of phantom limb pain, report researchers. A new test shows that VR technology can trick the amputee’s brain into thinking that it is still in control of a missing limb.
Engineers are using soft robotics technology to make light, flexible gloves that allow users to feel tactile feedback when they interact with virtual reality environments. The researchers used the gloves to realistically simulate the tactile feeling of playing a virtual piano keyboard.
