Dvorak keyboard layout | EPFL Graph Search

Dvorak ˈdvɔːræk is a keyboard layout for English patented in 1936 by August Dvorak and his brother-in-law, William Dealey, as a faster and more ergonomic alternative to the QWERTY layout (the de facto standard keyboard layout). Dvorak proponents claim that it requires less finger motion and as a result reduces errors, increases typing speed, reduces repetitive strain injuries, or is simply more comfortable than QWERTY. Dvorak has failed to replace QWERTY as the most common keyboard layout, with the most pointed-to reasons being that QWERTY was popularized 60 years prior to Dvorak's creation, and that Dvorak's advantages are debated and relatively small. However, most major modern operating systems (such as Windows, macOS, Linux, iOS, Android, ChromeOS, and BSD) allow a user to switch to the Dvorak layout. The layout can be chosen for use with any hardware keyboard, regardless of printed characters on the keyboard. Several modifications were designed by the team directed by Dvorak or by ANSI. These variations have been collectively or individually termed the Dvorak Simplified Keyboard, the American Simplified Keyboard or simply the Simplified Keyboard, but they all have come to be known commonly as the Dvorak keyboard or Dvorak layout. Dvorak was designed with the belief that it would significantly increase typing speeds with respect to the QWERTY layout by alleviating some of its perceived shortcomings, such as: Many common letter combinations require awkward finger motions. Some common letter combinations are typed with the same finger. (e.g. "ed" and "de") Many common letter combinations require a finger to jump over the home row. Many common letter combinations are typed with one hand while the other sits idle (e.g. was, were). Most typing is done with the left hand, which for most people is not the dominant hand. About 16% of typing is done on the lower row, 52% on the top row and only 32% on the home row.

Wind farm power density optimization according to the area size using a novel self-adaptive genetic algorithm

Fernando Porté Agel, Nicolas Otto Kirchner Bossi

This work studies the power density (PD) optimization in wind farms, and its sensitivity to the available area size. A novel genetic algorithm (PDGA) is introduced, which optimizes PD and the turbine layout, by self-adapting to the PD and to the solutions ...
