These scalar elliptic equations related to singular potentials, together with the corresponding elliptic systems, arise naturally in a wide range of physical fields and various economical prototypes [9].
Because these microchannels are fabricated using the foundry-based micromachining process, they present opportunities for economical prototyping and have great potential for integration with other microfluidic devices for system-level applications, such as DNA chip and lab-on-a-chip.
Especially, nozzle based techniques offer new opportunities thanks to the efficient usage of material and economical advantage in prototyping and single/small series component production.
By facilitating rapid, economical, low-risk prototyping, CFD modelling has already revolutionised research and development of devices such as stents, valve prostheses, and ventricular assist devices.
There is a broad social message in the largest piece on view, "Fly's Eye Dome," an adaptation of Buckminster Fuller's last geodesic dome, which offers a prototype for economical, ecologically sound and sturdy housing anywhere in the world.
The prototype proved economical in service as it used 10 percent less coal than the N class, but used 11 percent more water.
The exemplars themselves need not be stored in memory giving prototype theory an economical advantage.
A PEM cell converts 30% of the energy in its fuel into useful work, compared with barely 20% for an internal combustion engine, so Toyota is confident that even its early models will be at least 50% more economical than petrol engines.Both these prototypes are now on display at the Tokyo Motor Show.
Effective and economical arrangements of rotors are investigated with reference to prototype tall structures.
With an estimated prototype cost of US$3000, our system provides an economical solution, compared with the more expensive ones currently available.
