Optical field profile evaluation on silica high-mesa waveguide for infrared absorption sensing
No full textBreathe sensing system that incorporates waveguide gas cells has been proved to be handy for performing daily breath checks. One critical issue for high-sensitivity breath sensing has been high propagation loss. We previously proposed the utilization of a silica high-mesa waveguide due to its low propagation loss. However, till date, few studies have demonstrated that a certain portion of the propagation light profiles out from the waveguide that contributes to infrared absorption sensing so far. In this study, we provide experimental evidence that a certain portion of the propagation light profiles out on an actually fabricated silica high-mesa waveguide for the first time
Accelerating Evolutionary Computation Using Estimated Convergence Points
No full textⅠ.INTRODUCTION / Ⅱ.CONVERGENCE POINT ESTIMATION / Ⅲ.EFFECT OF ESTIMATED CONVERGENCE POINT FOR ACCELERATING EVOLUTIONARY COMPUTATION / Ⅳ.EXPERIMENTAL EVALUATIONS / Ⅴ.DISCUSSIONS Ⅵ.CONCLUSIONWe use the convergence points estimated by our
proposed method as elite individuals for evolutionary computation
and evaluate the acceleration effect and analyze the effect
and computational cost. The worst individuals in population are
replaced with the convergence points estimated from the moving
vectors between parent individuals and their offspring; i.e. these
convergence points are used as elite individuals. Differential
evolution (DE) and 14 benchmark functions are used in our
evaluation experiments. The experimental results show that use
of the estimated convergence points as elite can accelerate DE
search in spite of the calculation cost of the convergence points.
We finally analyze the components of the proposed estimation
method to improve cost-performance
