Sentence examples for efficient speeds from inspiring English sources

Its geared turbo fan technology allows different components in the engine to run at varying, more efficient speeds, which, the manufacturer claims, will improve fuel consumption by up to 20 per cent, cut carbon emissions by more than 3,000 metric tons per aircraft per year, and also slash aircraft noise by up to 75 per cent.

An element of the debate is the widespread belief that quadrupeds are constrained to run at optimally efficient speeds within each gait, whereas humans are equally efficient at all running speeds.

A combination of biomechanical and hydrodynamic factors make this an efficient speed at which to travel.

7. The Energy Saving Trust says that the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55-65mph.

The most efficient speed for the Winston team's car is about 34 miles an hour, said Jon Crim, another student and the mechanical specialist for the team.

As a commenter on the Web site LetsRun described the unique challenges of the quarter-mile: "You run through the metabolic stages and have to walk a tightrope between total physical destruction and continued highly efficient speed...

In this paper we focus on the train optimisation model to define energy- efficient speed profiles and the relative energy consumption, assuming train motion parameters as control variables.

To do so, an innovative optimization framework for the definition and the evaluation of energy efficient speed profiles, based on supply design modelling, is proposed.

Misconceptions about speed and travel time provide the potential for more effective communication with the driver about the momentary efficient speed as well as resulting time losses and fuel savings.

The framework operates on two levels: the first level generates energy efficient speed profiles with respect to timetable constraints, infrastructure characteristics and rolling stock features, and the second simulates these speed profiles on the rail network within the specific rail traffic conditions.

A numerical example based on a calibrated simulation model of the suburban S-Bahn S9 line that operates in the Canton of Zurich shows how energy efficient speed profiles can be defined considering the rail traffic influences, thus increasing the quality of the solutions.
