Mathematical models of structural optimization were established for the cam wave generator  then a conceptual model  by integrally taking its static and dynamic performance into consideration  which satisfied the model acted by four concentrated forces  while the dynamic optimum design was carried out. The topology optimization of the cam wave generator was performed based on artificial material density method  was obtained. And the size optimization of the cam wave generator was also executed based on the zero-order method in software Ansys after setting up its parameterized model. The optimized results indicate that its final volume declines to 1284.217mm3 from its 1397.830mm3  which reduced by 42.18% than the original volume of cam (2221.224mm3). Simultaneously  the static analysis and modal analysis were implemented  and the results show that the static and dynamic performance complies with the design requirements  proving that the results of dynamic optimum design are reasonable. The optimized results in paper are realizable in engineering. And the study method provides not only a reference to decreasing design mass and lowering inertia of the cam wave generator  but also an important basis of lightweight design of harmonic gear drive. 2011 IEEE.

Based on the modified coupled-wave theory  the emission characteristics  including threshold gain  photon density distribution in the cavity  and external differential quantum efficiency for second-order DFB lasers are investigated. Numerical simulation results show that for given device structure with wavelength of 1.55 m  the feedback coupling coefficient and the surface radiation coupling coefficient of the second-order grating have great influence on the emission characteristics of the device. By choosing different duty cycles of the grating  we can change the two coupling coefficients  which affect the emission characteristics. For an overall consideration  an optimal duty cycle of 0.43 is chosen. The optimized results show that the device works without degeneracy modes and spatial burning hole. Besides  the side-mode suppress ratio (SMSR) and external differential quantum efficiency reach as high as 42 dB and 47%  respectively. 2010 SPIE.

The immobilization of antibodies on solid surface has been widely studied in elucidating immunoassay and in developing immunosensor. In this paper  FITC-labeled goat anti-human IgG were covalently immobilized on 3-aminopropyltriethoxysilane (APTES) and glutaraldehyde (Glu) to modify the distal end of a fiber-optic probe. The higher density and stability of FITC-labeled goat anti-human IgG could be obtained on the fiber surface modified with APTES-Glu than that on the non-modified fiber surface by evanescent excited fluorescence spectroscopy. Furthermore  red shift of the FITC fluorescence dye emission peak was observed on different fiber surface  exhibiting different interaction between FITC- labeled antibody and surface. Finally  under these conditions antigen-antibody reaction was investigated as an immunosensor. Detection limit of the evanescent wave optic-fiber biosensor is 10ng/ml.
