Growing older is an inevitable part of life, and with it, our body slowly begins to show that. I recently started wearing eye glasses because my eyesight is weakening. It’s a little unnerving, but I am comforted by the ever-improving technology being produced. My hearing is still fully intact, but the same cannot be said for 17% (36 million) of American adults who report some degree of hearing loss. In most cases, regular hearing aids are sufficient in treating hearing […]

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.

Wind turbines are an expensive investment and once they’re up, they’re up. An article from last year’s COMSOL News points to how modeling can also help in remedying problems, if it’s too late to have built the perfect design from the beginning. With wind turbines, noise is of course the problem.

I had previously blogged about Thermal Cloaking, which uses layers of aluminum and paper to create an anisotropic structure and cloak a desired object. This differs from the “traditional” type of cloaking, of light and electromagnetic waves, which make use of metamaterials or layered structures that impose a negative refractive index to make the cloaked object appear transparent.

While you may think that the prevalence of lightning strikes, would be a reason for not wanting wind turbines in your backyard, noise is apparently another reason. While this has become less of a problem in recent years, the noise is still there, and is always there whenever the wind blows.

Many devices live with a dry, technical name that either basically says what the device does, or is an acronym of that dry, technical name. Very few get a nickname that sticks to become the industry standard.
