The optimal amount per week was 1 to 2.4 hours, the optimal frequency was less than or equal to 3 times per week and the optimal speed was "slow" or "average". [15] A recent meta-analysis on running/jogging and mortality, including more than 230,000 participants found that runners were at 27% lower risk of death than non-runners, during 5.5-35 ...
In other words, going between periods of efficient acceleration and gliding gives an overall efficiency that is usually higher than when cruising at a constant speed. Computer calculations have predicted that in rare cases (at low speeds where the torque required for cruising at steady speed is low) it's possible to double (or even triple) fuel ...
“According to research, only 2.5% of people can multitask successfully,” says time management strategist Kelly Nolan. “So there’s a 97.5% chance you, the person reading this, cannot ...
Choice of design depends on the goals: when designing a compiler, if fast compilation is the key priority, a one-pass compiler is faster than a multi-pass compiler (assuming same work), but if speed of output code is the goal, a slower multi-pass compiler fulfills the goal better, even though it takes longer itself. Choice of platform and ...
Therefore, making part A to run 2 times faster is better than making part B to run 5 times faster. The percentage improvement in speed can be calculated as = (). Improving part A by a factor of 2 will increase overall program speed by a factor of 1.60, which makes it 37.5% faster than the original computation.
The researchers claimed in 2015 that the leaf-like cells generated 47 percent more electricity than those without folds. Image credits: Sasha Weilbaker #8 Bullet Trains
On the faster speedways and superspeedways used by NASCAR and ARCA, two or more vehicles can race faster when lined up front-to-rear than a single car can race alone. The low-pressure wake behind a group's leading car reduces the aerodynamic resistance on the front of the trailing car, allowing the second car to pull closer.
