Cladding definition

Such a behavior of the total field is observed provided that the beam power is smaller than a definite value P which depends on the waveguide width (for a = 1.8pm, P 8). The spatial dynamics of a light beam with P > Pi is more complicated because nonlinear self-effects in radiation field increase so that the formation of soliton-like light beams propagating in the waveguide cladding is observed. 

Ivan Cantrell had been ordered to land his plane on a remote part of the city s aerodrome. Soldiers had surrounded the vehicle as they touched down, nervous men in ill-fitting khaki uniforms, squeezing the stocks of rifles which had been antique back in their grandfathers time. But dotted among them were several Confederation Navy Marines, clad in sleek one-piece suits which seemed like an outgrowth of rubbery skin. And their dull black weapons were definitely not obsolete. Louise suspected a single... 

The factors promoting corrosion of aluminium alloys are complex and interrelated. They often operate synergistically, making prediction of corrosion difficult. In wet storage of aluminium clad spent fuel, there are a number of corrosion mechanisms involved. The most important mechanisms as related to spent nuclear fuel are briefly discussed here. Other details and definitions related to aluminium corrosion can be found in the normative publications and ISO standards provided therein. 

Identification of the different barriers against radioactive releases (RRs), for PWRs typically the fuel cladding, the reactor vessel and primary coolant system boundaries and the containment/confinement) Identification of the possible challenges to each of these barriers Definition of a set of plant specific safety functions that are representative of the status/safety margins of each of the barriers Development of a tool — flow diagram, procedure, electronic system — to continuously monitor the status and challenges to each of the safety functions ... 

In the absence of material dispersion, pulse spreading on single-mode circular fibers is proportional to the distortion parameter D, as expressed by Eq. (13-18). To calculate this quantity for the clad power-law profiles, we first rearrange the definition as... 

The general profile n R) of a circular fiber has the form of Eq. (14-1)l If we consider fibers with a uniform cladding of index n, and recall the definition of... 

For the special case of the step profile, when n = in the core and n = in the cladding, the definition of A inside the back cover leads to... 

We relate the modal parameters to the propagation constants by equating real and imaginary parts in the definitions inside the back cover and retaining only the lowest-order terms in each case. In terms of the core and cladding power absorption coefficients, and a, defined in Eqs. (6-10) and (6-19), respectively, and the power attenuation coefficient y of Table 11-2, page 232, we obtain...
