These waterwheels generally used the energy of moving streams, but tidal mills also appeared in the 11th century.
In the present study the automatic sampler was attached to the moving stream of grain in the end of a short mixer.
"Amateur scholars will attempt to put stakes in a moving stream.
The most common mining technique in that era involved shovelling earth into a wooden trough, called a sluice box, then directing a swiftly moving stream of water over it, in the hope of washing away everything but gold.
On the basis of a series of engineering experiments aimed at gathering data on the forces acting on wing shapes in a moving stream of air (1887 91), Langley had concluded that "mechanical flight is possible with engines we now possess".
Water and solutes pass through pores in the surface epithelium of the mucosa by active transport and solvent drag; i.e., solutes are carried in a moving stream of water that causes an increased concentration of solute on the side of the membrane from which the water had originally come.
Charts of the probability that a bacterium will have a given orientation, at three different positions in the moving stream of water, are plotted based on experimental data (solid lines) and mathematical models (dashed lines), showing how well the two agree.
The targeted works presented in this section provide empirical support to further explore and develop novel Deep Learning algorithms and architectures for analyzing large-scale, fast moving streaming data, as is encountered in some Big Data application domains such as social media feeds, marketing and financial data feeds, web click stream data, operational logs, and metering data.
Then there's mechanical turbulence, which occurs when physical structures such as mountains and buildings disrupt wind currents, much like a boulder causes ripples in a moving stream.
Following Hill's classical representation of the flow field within a stationary droplet in a uniformly moving stream by a single ring-vortex, a modified stream function is introduced that represents a stationary droplet by two ring-vortices that are situated at the stagnation-point of two counterflow jets.
