Coupling efficiency in optical fibers is influenced by the numerical aperture, as a higher numerical aperture typically allows for more efficient coupling of light into the fiber core. A larger numerical aperture enables the fiber to capture more light, which helps to improve the efficiency of light transmission into the fiber. Thus, a higher numerical aperture can lead to better coupling efficiency in optical fibers.

Thermal coupling refers to the transfer of heat between different components of a system. In the context of a heater, efficient thermal coupling ensures that heat is effectively transferred from the heating element to the surrounding environment. Poor thermal coupling can result in heat loss and reduced efficiency of the heater, as more energy is required to maintain the desired temperature.

coupling is a computer program, which is meant for the maintenance of the cohesion , coupling is inversely proportional to cohesion. When coupling and cohesion is combined then it acts as support to the high readability and maintainability of a computer program.

in certain power amplifiers(cls A,cls C etc.) the output sometimes not directly taken. rather it's coupled with transformer and then transferred power is applied to the load..this is transformer coupling.....
there are two main reasons to do so
1. in order to increase the efficiency.(exmpl: efficiency of class A power amplifier increase by almost 25%)
2.in order to get smooth i.e; distortion less output..

RC COUPLING :-
is the most Commonly used Coupling Between the two stages of a cascaded or
multistage amplifier because it is cheaper in cost and Very compact circuit
and provides excellent frequency response.
TRANSFORMER COUPLING :-
Impedence Coupling results in more efficient amplification
because no signal power is wasted in Inductor L.
Such Coupling has the drawback of being larger, Heavier and Costlier than the RC COUPLING.
Impedence Coupling is rarely used beyond audio range .

All automatic transmissions use something called a "torque converter". It is a fluid coupling that utilizes a turbine blade to increase efficiency. It takes the place of a clutch in a manual transmission car to allow the engine to continue running while the vehicle is stopped. If you explained why you are asking the question it may make it easier give a meaningful answer.

half coupling used to take branch from header ie: 2" header to 3/4' branch.
where full coupling used to connect to straight pipe. ie: 2" to 2" pipe connection.

It is a fluid coupling using a viscous (thicker type) fluid, similar to the coupling between the drive and driven impeller of an automatic transmission in a car.

The female coupling connects to the engine (nozzles have female couplings, engine apparatus usually has male connections), so the male coupling always points towards the fire. With that, if you're following a hose, say out of a building, you would want to find the male coupling and follow the hose behind the male coupling.

A chain in polythene can terminate by coupling through a reaction that involves the joining of two polymer chains. This coupling reaction can occur during the polymerization process or be induced post-polymerization through the use of coupling agents. Termination by coupling can lead to the formation of branched or cross-linked structures, altering the properties of the polythene material.

DC coupling on the input/output will always give higher gain because AC coupling involves inserting a capacitor, which adds impedance and augments the signal. AC coupling is sometimes necessary though, for such purposes as eliminating DC offset on the base of a transistor, or eliminating a DC offset in a single supply opamp circuit.

Aliphatic amines do not typically give coupling reactions due to their limited aromatic character, which is necessary for coupling reactions to occur effectively. Aromatic amines are more likely to undergo coupling reactions because they possess a delocalized pi system that stabilizes the intermediates formed during the coupling process.

Scoop coupling is nothing but a fluid coupling works based on the hydro dynamic principle.
Scooping is the collecting the oil from the working chamber(space between pump wheel and turbine wheel) which will effects the transmission.

Using the cosine law of illumination, if two cables are laid at right angles, since cos 90 = 0, the coupling will be the lowest possible.
If the two cables are laid parallel, the coupling will be maximum.
Be aware that shielding or twisting of cable pairs reduces the coupling effect.
