While alternative energy is the energy of the future, fossil fuels are the energy of right now. Coal, especially, is still heavily relied on for energy production and is a primary source of electricity generation in many countries including the US and China. In fact, world coal consumption is actually increasing year-to-year. Scientists need to be concentrating on how to make alternative energies more widespread, but they also need to make coal a better, more efficient fuel source. Designing systems […]

Spinal cord stimulation (SCS) is a treatment for chronic back pain that has been around for over 40 years. It involves implanting electrodes that apply electric potentials directly to the spine, interfering with the human pain signaling circuitry. The body attempts to send pain signals to the brain, but the electrodes act as a barrier preventing the signals from reaching the brain. Although an overall successful method for treating back pain, researchers have been improving on the design since the […]

Much has been written lately about increasing the energy efficiency of cars. Batteries and fuel cells are very hot topics, and not so long ago I blogged about the University of Michigan’s use of solar cells to fully power a car. Yet, even on the smallest of scales, such as the sensors in your car, improvements are being made. Utilizing a MEMS (Micro Electromechanical System) piezoelectric energy harvester, Alexander Frej and Ingo Kuehne at Siemens Corporate Technology in Munich are […]

Düsensauginfiltration (DSI) is a novel technique for lowering water levels at mining and construction sites while not actually having to transport the water away from these sites. This came to my attention at the latest COMSOL Conference in Stuttgart. There, Ph.D. student Yulan Jin and Assistant Professor Dr. Ekkehard Holzbecher from the Georg-August University in Göttingen, Germany was presenting their research into this groundwater lowering technique.

One of the interesting stories to come out of the latest COMSOL News concerned a couple of great researchers, Dr. Ozgur Yildirim and Dr. Zihong Guo, and how they use simulations in their inventing process. They work in an invention/prototype laboratory in Bellevue, WA for Intellectual Ventures, a global leader in the business of invention.

In these days of globalization, keeping the world connected is imperative. Information needs to pass as freely and quickly as possible in order to keep markets up-to-date with the latest news and to ensure that commerce can be conducted without hindrance (at least of the technical kind). So what do you do – look to the sky? The answer is no; in fact, 99% of this information is carried by undersea cables. These unsung heroes sit at the bottom of […]

How do you simplify a 3D geometry to reduce the computational resources required to model it? Do it in 2D. What if the phenomenon can only be properly simulated in 3D? Find the planes of symmetry and reduce the size, most engineering objects are symmetric in some way. What if there is no symmetry, such as the propagation of random cracks through a steel pipe? Well, as this story from COMSOL News shows, there are other methods, such as using […]

In an earlier blog post, I commented on how acoustic waves are being used in a biomedical setting, to identify malaria in small fluid samples. A more traditional use of piezoelectric devices was written about in the latest COMSOL News. Here, an Italian company, Esaote S.p.A., uses them to produce improved ultrasound imaging systems.
