Beam combining techniques have become an important tool in design of high-power highbrightness laser systems [1]. Maximum power that can be obtained from single high-power amplifiers is usually limited by thermal distortion of active medium and beam quality degradation in solid-state lasers or non-linear effects and active fiber damage in fiber lasers. Beam combining offers an alternative solut...

An ultrastructural study has been undertaken on the equatorial (sensory) region of the rat muscle spindle. Two kinds of intrafusal muscle fibers, a nuclear bag fiber and a nuclear chain fiber, have been identified in this region on the basis of fiber diameter, nuclear disposition, and M-band appearance. The large-diameter nuclear bag fiber contains an aggregation of tightly packed vesicular nuc...

Fiber Bragg gratings inscribed with a femtosecond laser using the point-by-point (PbP) technique have polarization dependent grating strength (PDGS) and exhibit birefringence. In this paper we quantify the dependence of these two properties on the ellipticity, position in the core and size of the micro-voids at the center of each refractive index modulation. We demonstrate that the effective mo...

Textile composites describe a broad range of polymer composite materials with textile reinforcements, from woven and non-crimp commodity fabrics to three dimensional textiles. In a general manner textile composites are based on textile preforms manufactured by some textile processing technique and on some resin infiltration and consolidation technique. Due to the complex three-dimensional struc...

this thesis is going to delineate the concept of the reader as implied in 18th century literary theory; based on the study of the major reader oriented elements of criticism of the age-taste, the sublime, and aesthetic pleasure-its aim is to explain what sott of reader is implied and what kind of response on the part of the reader is proposed in 18th century english literary theory and aestheti...

To manufacture a high-performance structure made of continuous fiber reinforced plastics, Liquid Composite Molding processes are used, where liquid resin infiltrates the dry fibers. For good infiltration quality without spots, it is important to predict flow correctly. Knowledge local permeability an essential precondition for mold-filling simulations. In our approach, intra-bundle parallel and...

There has been considerable interest recently in the development of fiber-optic sensors based on in-fiber Bragg gratings (FBG's), which can be written into Ge-doped fibers by use of a transverse holographic method.' The use of such elements for distributed strain or temperature sensing in advanced composite or other structural elements and their use as inline reflectors in interferometric syste...
