The Linac-MR Project: Tumor Tracking and Treatment
Not too long ago, my colleague Jennifer wrote a blog post about the Cross Cancer Institute, and the research being conducted there into the design of a new device for treating cancerous tumors. The device, known as the Linac-MR, is revolutionary due to its ability to both image and treat cancer cells simultaneously — a capability that had previously been regarded as near impossible due to the conflicting physics interactions involved. Such a device would allow for extremely precise radiation […]
Optimizing Recloser Performance with Simulation
During snow storms or windy days, a branch might break and short-circuit a power line’s electric current as it falls. The first task of a recloser is to interrupt this short-circuit, i.e. to open or disconnect the affected overhead line from the feeding network source. The second task is to try to re-establish power after a short time by to re-closing the line, taking advantage of the fact that most of the reasons for a short-circuit of an overhead line […]
COMSOL Multiphysics Version 4.4 Released Today
You’ve seen glimpses of our new software release at the COMSOL Conference and perhaps engaged in commentary around it in social media. Today marks the official release of COMSOL Multiphysics version 4.4, and you can now learn about the software updates in detail and download it if you are on subscription.
COMSOL Conference 2013 Bangalore Award Winners
After having excellent poster and oral presentation sessions at the COMSOL Conference 2013 Bangalore, winners for the top papers and posters were announced during the award ceremony. Selecting the best ones was indeed the toughest decision that the Program Committee had to make. It was observed that the presenters had conducted rigorous analyses using COMSOL Multiphysics, and many of them also had experimental validation for their work. Now I would like to congratulate the winners once more, and allow you […]
COMSOL Conference 2013 Bangalore Keynote Sessions
At the COMSOL Conference 2013 Bangalore we had three speakers who delivered each of their keynote talks to a full house. It was an interesting mix, with one speaker each from the government, academic, and corporate backgrounds. Here is a glimpse of what attendees got to listen to.
Flying Under the Radar with Altran Group’s Stealth Antenna Design
The unique properties of radio frequency (RF) electromagnetic radiation enabled countless innovations in recent decades, including the development of radar systems. Depending on the frequency, RF radiation can travel through solid insulating structures, typical atmospheric conditions, clouds, and rain with only minimal losses allowing for its use over long ranges and in varied weather conditions. The aerospace and defense industries have expanded and progressed rapidly as a result of using radar systems for detection and classification tasks to determine if […]
Thermal Insulation with Bubbles is Better
As a nuclear engineer, I’ve attended many thermal engineering classes. Whereas I’ve enjoyed learning techniques to enhance heat transfer, I’ve also found fascinating those applications where it is important to reduce heat transfer using the right choice and combination of materials and shapes. The design of this is vital for many industries, including the building and aerospace industries. Lately, I came across an interesting example of thermal insulation in the most mundane of these things: clothing design. I had to […]
Efficient Solar Panel Design Improves the PV Industry
Solar photovoltaic (PV) cells are semiconductor devices that directly convert solar energy into electricity or voltage using the photovoltaic effect. These PV cells are more commonly known as solar cells, or solar panels, and in 2012 they produced roughly 93 terawatt-hours (TWh) of electricity — enough energy to power over 20 million homes. Because the cells must be directly exposed to the sun’s rays, they are housed outdoors where the panels are affected by the elements. Therefore, the cells must […]
