Optimizing network software to advance scientific discovery

High-performance computing (HPC)—the use of supercomputers and parallel processing techniques to solve large computational problems—is of great use in the scientific community. For example, scientists at the U.S. Department ...

Engineers develop concept for hybrid heavy-duty trucks

Heavy-duty trucks, such as the 18-wheelers that transport many of the world's goods from farm or factory to market, are virtually all powered by diesel engines. They account for a significant portion of worldwide greenhouse ...

Mystery of negative capacitance in perovskite solar cells solved

On the verge of outcompeting current thin-film solar cells, perovskite solar cells seem to embody an ideal solar cell with high efficiency and low cost. However, they have poor long-term stability, which remains a challenge. ...

Team predicts the useful life of batteries with data and AI

If manufacturers of cell-phone batteries could tell which cells will last at least two years, then they could sell only those to phone makers and send the rest to makers of less demanding devices. New research shows how manufacturers ...

Students design 3-D-printed optical mapping system

Two School of Engineering and Applied Science students designed a 3-D-printed system for optical mapping, a leading tool in cardiac electrophysiology used to study arrhythmia mechanisms. The system can be implemented for ...

A robotic leg, born without prior knowledge, learns to walk

For a newborn giraffe or wildebeest, being born can be a perilous introduction to the world—predators lie in wait for an opportunity to make a meal of the herd's weakest member. This is why many species have evolved ways ...

Engine

An engine is a mechanical device that produces some form of output from a given input. An engine whose purpose is to produce kinetic energy output from a fuel source is called a prime mover; alternatively, a motor is a device which produces kinetic energy from other forms of energy (such as electricity, a flow of hydraulic fluid or compressed air). A motor car (automobile) has a starter motor and motors to drive pumps (fuel, power steering, etc) – but the power plant that propels the car is called an engine. The term 'motor' was originally used to distinguish the new internal combustion engine -powered vehicles from earlier vehicles powered by a steam engine (as in steam roller and motor roller).

Military engines included siege engines, large catapults, trebuchets and battering rams.
