We analyze the impacts of vindictive bidding behaviors in the non-decreasing sponsored search auction. The bidding behaviors are classified into malicious, selective, conservative, and rational actions based on the vindictiveness degree. Given different vindictive bidding behaviors, we evaluate variance of the revenue of the search engine provider (SEP) and advertiser¡¦s profit. According to the experiment,...
We demonstrate pulsewidth tunable Q-switched erbium fiber lasers using in-line high extinction ratio (> 30 dB) abrupt-tapered fiber Mach-Zehnder block filter and tunable Fabry-Perot filter in laser cavity. The pulsewidth can be tuning over 78ns~23ms.
A Lagrange multiplier optimization method to the inverse design problems for complex LPGs was developed in the present study. For the first time, an EDFA gain flattening LPG is successfully synthesized by the proposed algorithm.
An evolutionary programming method for synthesizing advanced fiber gratings is developed. Two practical design examples including dispersion-less FBGs with shorter grating-length and gain flattening LPGs for entire EDFA band are demonstrated for the first time.
