Using lorem ipsum to focus attention on graphic elements in a webpage design proposal

* Reynolds, John C. Using category theory to design implicit conversions and generic operators.

Using this design, Crewe demonstrated the ability to image atoms using annular dark-field imaging.

Using its inventory of easy-to-service Ford mechanicals built up during World War II and bodywork of Allard's own design, three post-war models were introduced: the J, a competition sports car ; the K, a slightly larger car intended for road use, and the four seater L. Sales were fairly brisk for a low-volume car, and demand was high for cars in general, which led to the introduction of several larger models, the M and N.

Using a hull mounted gun, the M3 design was produced quicker than if a turret mounted gun design had been manufactured.

High platform design ( Using outside steps to avoid having a level entry from the platform ) is troublesome.

Using heuristic evaluation prior to user testing will reduce the number and severity of design errors discovered by users.

Using E-Cash and other modern cryptographic methods, it is possible to design systems that do not know where individuals are, but are still able to enforce fares.

Using much of its old on-screen appearance design features, it went from a basic blue setting to a more orangish-gold setting.

Using previous results to design further decisions and experiments is a central concept of adaptive management.
