SIAM Journal on Applied Mathematics, Vol. 79, No. 6 (2019), pp. 2663-2687 (25 pages) We analyze sound propagation in a waveguide filled with a random medium modeled by small-amplitude spatial and ...

Handheld devices can scan the lower limbs of a patient and 'listen' to the blood flow, providing vital early indication of problems that could lead to strokes or heart attacks. But inexperience or ...

Aerodynamic optimisation is of paramount importance in improving the design of aircrafts, automobiles as well as turbomachinery to reduce energy consumption and improve energy production efficiency.

Testing a total artificial heart To observe real-time blood flow in an artificial heart in the MRI, researchers at Linköping University built a full-scale model of the human circulatory system.

Though Doppler seems relatively simple to implement in ultrasound, analog performance in the latest systems has much higher, more-difficult-to-achieve specifications than standard black-and-white ...
