This is the idea that a complex and autopoietic system must relate to its environment, and the internal structure becomes coupled to relevant features of that environment. In complexity terms the environment selects which of the systems attractors becomes active at any time, what is also called situated or selected self-organization.

two cores are brought closer or the interaction distance is increased the coupling increases to a maximum of 100%, and if the fibers are matched, reduces to zero and then begins to increase again. This cyclic coupling function shows a beating of the power from one fiber to the other, the number of beats being dependent on the positioning of the cores. A 3dB, 50/50 coupler is set to mid point of the first upbeat.

The most common coupling fluid in use is DI water. Other fluids can be used but chances are that they will absorb more ultrasound than water and at very high frequencies may cause poor signal levels. The instrument operator must choose a fluid that will not harm the sample or the instrument. Alcohols such as IPA are the next most common fluid.

A T-coil is a device in some hearing aids that allows a hearing aid to pick up low-level magnetic signals from a phone. When a T-coil is used, the microphone on the hearing aid is turned off and the sound from the phone is delivered to the hearing aid via the magnetic signals. Because the microphone is turned off, T-coils help eliminate backgrounds noises and help the user hear only the phone conversation.

This involves the conservation and restoration of the painting’s supporting material. i.e. the canvas, panel, board etc. In some cases this can have deteriorated due to, for example, damp or dry environments, or impact damage. We can repair a canvas that has become too weak to hold the paint on its original plane, or has been torn. These can be held with a supporting canvas and the process is called lining. A split panel can be repaired, or a warped panel straightened.

Yes. And tests indicate Thermapan SIPs are significantly stronger than conventional 2x4 or 2x6 walls.In fact, houses built with Thermapan SIPs have withstood the force of Class 6 hurricanes, such as Andrew, Hugo and Mitch.

Majestic Pools are designed with A-frame and deck support braces (10 GA, bolted with 3/8 inch bolts) every 3 to 4 feet around the perimeter, making the deck an integral part of the pool. Thus, making a self supporting unit. All our competitors use 14 GA supports (lighter) with 1/8 inch screws. The water is the very last thing that goes into our pools, as we do not need the water to hold our walls as many other types of construction do. This is important if you ever have to drain the pool.

Structural soil refers to a group of soil mixes that are designed to be both load bearing AND to support tree growth. Because they are load bearing, they can be used under pavement, including streets. They typically function by using large gravel or similar material that form a lattice work that provides the support needed to hold up pavement. A good topsoil is mixed in and fills the voids between the gravel, providing uncompacted growing space, moisture and nutrients for roots.

A structural fiber is one that is less stretchy than the concrete it is reinforcing. This is measured by the Young's Modulus of Elasticity. To be considered structural, generally you must have a Young's ME greater than 25. There are sophisticated measures, like the ability to strain-harden, that can be considered, but the ME is a good basic parameter for separating the stiff fibers from the stretchy ones.

This is the conversion of light from one axis of a polarization maintaining fiber into the orthogonal axis. It is caused by local stress induced birefringence that shifts the fast and slow axes or in the case of a coupler, a misalignment of the polarization axes in the coupling region. Cascaded components with cross coupling used with long coherence length sources can display amplitude modulation unless they are thermally controlled.

The purpose of the Flexidyne? in the Mini-IMP drive train is to act as a torque limiting, "slip-clutch" device which slips ONLY during initial engine start and most importantly when the engine is accelerating or decelerating through various narrow RPM ranges at which a highly destructive, torsional resonant feedback occurs. At all other engine speeds, the Flexidyne? is "locked up" and operates with no slippage and thus no power loss or heat.

In multi-antenna systems you will always get some mutual coupling between antennas but this can be minimized by ensuring they are exactly 90? to each other and by 'nulling-out'. 'Nulling-out' antennas minimizes the mutual coupling effects and is done by attaching one antenna to an oscilloscope, so that the induced voltage can be read whilst the other antenna connected as normal but with the transmitter on 100%. Moving the antenna to the null position can reduce the induced voltage.

R : Our distributor in your region or country will be pleased to advise you on the sell of coupling gel.

Extensive field testing by ACEEX has shown that the attenuation between phases is minimal. The average data rate degradation that results from crossing phases in the same home is approximately 4%. No additional equipment is required to enable communication between phases. If the powerline characteristics degrade during a session, Powerline product will sense the change and automatically adapt to provide the most reliable connection.

The Hitch-Coupling Tightener (Item # 020.6) reduces vibration by eliminating "play" at the junction between your hitch receiver and the StowAway2 frame. To see how the Hitch-Coupling Tightener installs, please view the Hitch-Coupling Tightener Instructions in PDF or DOC format. This vibration does not affect the performance or safety of the StowAway2 Cargo Carrier, but can be a nuisance on uneven road surfaces. This item is included FREE with any item on a Swingaway frame.

People completing the Structural Integration process have reported improvement with a wide variety of conditions such as: Asthma, bursitis, carpal tunnel syndrome, coccyx injury, fibromyalgia, frozen shoulder, golf elbow, headaches, hip replacement, infertility, knee replacement, kyphosis of the spine, lordosis of the spine, migraines, neck pain, osteoarthritis, plantar fasciitis, post surgery recovery, post delivery recovery, rotator cuff rehabilitation, reflux, sciatica, shin splints, sports i.

Although people often come to Structural Integration seeking relief from their pain, the process of Structural Integration offers so much more. Personal growth, emotional balance, psychological transformation, and increased sense at wellness are the less tangible but often most powerful aspects of the process.

Attenuation, expressed in dB per unit length, is the sum of the power loss along the length of the cable. Coupling Loss is the difference between the power that is contained in the cable and the transmitted power received by a dipole antenna located a fixed distance away.

Answer: Using a magnetic coupling eliminates the rotating propeller shaft and the shaft seal which are the major cause of leaks and failures with traditional thrusters. The propeller shaft seals in use today were all designed for use at or near the surface where the pressure is relatively low - they inevitably fail when subjected to the pressure of typical ROV and AUV operations (100m to 10,000m).
