The imaging algorithm can incorporate new data into the image in a recursive fashion which causes image background noise to diminish over time. 该成像算法能够以递归方式将新的数据融入到成像中,这使成像背景噪声随时间减少。
The concept of technology life circle is introduced in the second model and the profit flow will not diffuse according to single geometric brownian motion. Utilizing dynamic programming approach the model calculates the patent value and investment threshold value with a backward recursive fashion. 第二个模型中引入了技术生命周期的概念,标的资产不再按照单一几何布朗运动变化,模型利用动态规划方法倒推计算出任意时点的专利价值和投资阈值。
