( 1990 ) carried out a radial velocity ( Doppler shift of spectral lines ) study of the star in April and May 1988, which showed variability with a frequency of the order of a few microhertz, the highest peak corresponding to 4. 3 μHz ( 2. 7 days ) with an amplitude of 60 ms < sup >− 1 </ sup >, with a frequency separation of ~ 5 μHz.

Tau Ceti was a target of a few radial velocity planetary searches, which have failed to find any periodical variations attributable to planets.

Most radial engines use overhead poppet valves driven by pushrods and lifters on a cam plate which is concentric with the crankshaft, with a few smaller radials, like the Kinner B-5 and Russian Shvetsov M-11, using individual camshafts within the crankcase for each cylinder.

However, very few were delivered with the radial tires because of manufacturing problems encountered by supplier B. F. Goodrich.

Most Pectinidae have radial ribs and concentric ridges, although a few are smooth.

The AAPS exploits the high stability of the University College of London Echelle Spectrograph ( UCLES ) to obtain the few meters per second precision in measurements of the radial ( line-of-sight ) velocities of stars necessary to detect the reflex Doppler motion induced by the presence of a planet.

Although radial symmetry is usually given as a defining characteristic of radiates, a few members of the class Anthozoa, which are now considered as the most basal and oldest group of cnidarians, are actually bilateral symmetric.

# Build non-sticky frame lines attached to supporting objects and a few initial radial lines.

In an environment with few or no directional cues ( for instance, a circular environment surrounded by black curtains ), place fields will tend to have a fixed radial position, but the entire set of place fields may rotate around the maze as predicted by a theory that rats are slowly losing their orientation.

At VLF frequencies the resistance of the soil becomes a problem, and the radial ground system is sometimes raised and mounted a few feet above ground, insulated from it, to form a counterpoise.

Applications of control methodology have helped make possible space travel and communication satellites, safer and more efficient aircraft, cleaner auto engines, cleaner and more efficient chemical processes, to mention but a few.

Many early aircraft engines ( and a few in other applications ) had the crankshaft fixed to the airframe and instead the cylinders rotated, known as a rotary engine design.

The LH Torana was one of the few cars worldwide engineered to occupy four -, six-and eight-cylinder engines.

Since very few actual implementations of heat engines exactly match their underlying thermodynamic cycles, one could say that a thermodynamic cycle is an ideal case of a mechanical engine.

This technique is limited to the few engines and software tools that support it.

Heat-engine-powered generators are nearly universal, ranging from small engines producing only a few kilowatts to utility-scale generators with ratings up to 800 megawatts.

A few early gas engines had double-acting cylinders, but otherwise effectively all internal combustion engine pistons are single-acting.

Relatively few of the wiki engines currently in use were created after 2006.

General Motors did not succeed in having a Wankel engine meeting both the emission requirements and having good fuel economy, so in 1974 the company canceled its development, although GM claimed having solved the fuel economy problem and having obtained engines with a duration above 530, 000 miles ; unfortunately they just published a few papers on the results of their research.

Mistral claims to have overcome the challenges of fuel consumption inherent in the rotary, at least to the extent that the engines are demonstrating specific fuel consumption within a few points of reciprocating engines of similar displacement.

Although the rule still applies, the visible fuselage " waisting " can only be seen on a few aircraft, such as the B-1B Lancer, Learjet 60, and the Tupolev Tu-160 ' Blackjack ' — the same effect is now achieved by careful positioning of aircraft components, like the boosters and cargo bay on rockets ; the jet engines in front of ( and not directly below ) the wings of the Airbus A380 ; the jet engines behind ( and not purely at the side of ) the fuselage of a Cessna Citation X ; the shape and location of the canopy on the F-22 Raptor ; and the image of the Airbus A380 above showing obvious area rule shaping at the wing root, which is practically invisible from any other angle.
