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.

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.

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.

Today, guest blogger and Certified Consultant Mark Yeoman of Continuum Blue shares a numerical modeling example for RFID applications. We’ll look at how we can make use of COMSOL Multiphysics® simulation software to determine the operating read range of a passive RFID tag powered by a reader’s interrogating field. Additionally, we will look at how we can maximize this operating range by optimizing the tag’s antenna design.

The first stop of the COMSOL Conference 2014 has now come and gone. The event brought together over 320 simulation practitioners from the worldwide multiphysics community to the unique setting of Churchill College in Cambridge, U.K. I would like to thank everyone who made the trip and to share with you some photos from the conference.

People are always asking how the performance of COMSOL Multiphysics® simulation software will improve on a parallel system, especially now that large multi-core desktop computers are relatively inexpensive and it’s easy to rent time on cloud services like the Amazon Elastic Compute Cloud™. It turns out, though, that it’s not always possible to get faster performance just by throwing more hardware at the problem. To understand why, let’s take a conceptual look at computers and the algorithms COMSOL® software uses.
