The Mystery Behind the Earth’s Magnetic Field Flip
While the earth’s magnetic field typically remains stable, studies have shown that irregular intervals known as geomagnetic reversals have occurred throughout history. Here, we investigate the background behind these flips and how a new study has provided surprising details into the most recent reversal.
Green Energy Management for Communication Systems
The communication network wasn’t designed to carry the amount of traffic that is currently transmitted around the world on a daily basis. With the rapid expansion in data traffic and the exponential growth in high-speed communications, the current network is coming under increasing strain. At Bell Labs, researchers are looking into ways to improve energy efficiency through the use of optimized electronics cooling and energy harvesting technology. Two new energy-savings approaches developed by the group promise significant savings.
Yield Surfaces and Plastic Flow Rules in Geomechanics
In order to ensure safe geotechnical building methods, specific applications require certain foundations and structure reinforcements. Tests are quite expensive to carry out, so simulation can be really useful and even essential. Many numerical models have been developed to give a deep insight into soil behavior. Here, we introduce the most widespread models for soils available in COMSOL Multiphysics and analyze a tunnel excavation example.
Modeling Reacting Flow in Porous Media
For anyone interested in modeling chemical reactions and/or flow through porous media, we have created a video to demonstrate how COMSOL Multiphysics simulation software handles such applications. Consider this your interactive tour of the model documentation for our porous reactor model.
Ada Lovelace Day, Celebrating Women in STEM
Today, many are celebrating Ada Lovelace Day around the world. This day is not a public holiday, but a day to honor women in science, technology, engineering, and mathematics (STEM).
Learning with Technology: 3D Printing in the Classroom
Over the years, the size and cost of 3D printers have decreased, offering new uses for this growing technology. In response to this development, more and more teachers have begun to utilize these devices within their classrooms, helping students learn in a hands-on way.
Blue LEDs Recognized with 2014 Nobel Prize in Physics
Since 1901, the Royal Swedish Academy of Sciences has recognized significant contributions to the field of physics with a Nobel Prize award. This year’s Nobel Prize in physics was presented to a team of scientists from Japan and the U.S., recognizing their work in developing blue light emitting diodes (LEDs). Let’s take a closer look at the innovative research behind this lighting technology.
Accounting for Heat in the Design of Lithium-Ion Batteries
In the performance of lithium-ion batteries, thermal management is an important element to consider. Through modeling and simulation, you can improve the design process by analyzing how heat is transferred within the energy source.
