Hybrid Linac-MR for Real-Time Image-Guided Radiotherapy
A team of medical physicists at the Cross Cancer Institute in Alberta, Canada has come up with an innovative approach to treat cancer. In affiliation with The Linac-MR Project, the team led by Gino Fallone aims to improve the accuracy of cancer treatment by reducing damage to healthy tissue surrounding a tumor site, while ensuring the tumor receives the intended radiation dose. They are accomplishing this through the development of a hybrid linear particle accelerator (Linac) integrated with magnetic resonance […]
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 […]
Fluid-Structure Interaction (FSI) using COMSOL Multiphysics
Today we have the pleasure of welcoming Nagi Elabbasi of Veryst Engineering as a guest blogger. Read on to see what this COMSOL Certified Consultant has to say about fluid-structure interaction. Two weeks ago I led a webinar on fluid-structure interaction (FSI) using COMSOL Multiphysics. FSI involves coupling between a deformable or moving structure and a surrounding or internal fluid flow. There is a growing number of engineering and scientific problems where a purely structural or purely CFD analysis just […]
Inertial Focusing, a Counterintuitive Approach to Concentrate Cells
Suppose we have a rectangular microchannel containing a laminar flow with Reynolds number Re = 1. Next, let’s randomly distribute suspended particles at the channel’s inlet. Given that there are no external forces acting on these particles, you would intuitively expect that the particles would trace the fluid streamline. However, scientists from Massachusetts General Hospital (MGH) and Veryst Engineering would disagree, and their research findings suggest a completely different pattern than what would be expected. The researchers claim that depending […]
Laser Beam Welding Gets a Magnet Make-Over
Our day-to-day lives are dependent on the safety of technical systems and processes. We blindly trust that reactor vessels withstand the test of time, that the train or ship we’re on does not break down. These metal structures, in turn, rely on accurate welding processes. Here’s where BAM Federal Institute for Materials Research and Testing comes into the picture. BAM researchers have been working on improving upon the high-power laser beam welding process in order to promote safer and more […]
A Multidisciplinary Approach to Electronics Design
Sharp is a powerhouse in the electronics industry, involved in televisions, liquid crystal displays, LED lighting systems, solar cells, multi-function business machines, and many other electronics-based products. One of a global network of Sharp R&D laboratories, Sharp Laboratories of Europe (located in Oxford, England), has been busy researching and developing LED lighting, display technology, microfluidic lab-on-a-chip, and energy systems for incorporation into Sharp’s products.
Thermal Analysis Measures Blistering Heat
If you roast a turkey for dinner and you need to check the temperature, the technology exists to find it. But what happens if the temperature is so hot that a consumer-grade thermometer, or any man-made device, really, would instantly melt and be destroyed? This might not be a common occurrence in your kitchen, but it is a real concern in blast furnaces, where temperatures can reach close to 1,500°C. Simply guessing is far from safe. Luckily, by simulating with […]
A Recipe for Induction Stove Design Using Multiphysics Simulation
When I was little, I used to love spending the night at my grandparents’ house, where I was allowed to watch TV, stay up late, and in the morning, help my grandmother make pancakes. The hardest part was always waiting for her old, slow electric burner to heat up — to my six-year-old self, it seemed to take hours for the burner to become hot enough after we’d finished mixing the batter. Luckily for me, and for other impatient chefs […]
