一种无先验地图的移动机器人导航方法

为了提高移动机器人在复杂环境下的无先验地图导航算法模型训练速度及导航成功率,提出一种基于深度确定性策略梯度(deep deterministic policy gradient, DDPG)的移动机器人导航方法。利用2D激光雷达的均匀分布测距信息,降低环境噪声的干扰及高维度环境信息的计算量;采用人工势场法构建移动机器人从初始位置到目标点过程的奖励函数;通过Actor-Critic网络结构提高模型训练的稳定性和泛化能力。实验结果表明,提出的方法具有模型训练速度快、导航成功率高及泛化能力强等优点。

Two new marine species from South Korea with remarks on the family Stylochidae (Acotylea,Polycladida, Plathelminthes)

Two new species of acotylean Polycladida are described from Korea, Munseoma maculata gen. et sp. nov., Callioplanidae, and Crytostylochus koreensis sp. nov., Stylochidae. Munseoma maculata is characterized by a small free prostatic vesicle but only indistinctly cut off from the ejaculatory duct; a Lang's vesicle is present. Crytostylochus koreensis possesses a prostatic vesicle with tubular lining of radial arrangement. Each papillate tube is connected via a glandular duct to a single extra‐vesicular gland attached to the muscular wall of the prostatic vesicle. That morphological feature forces discussion of the relationships within the family Stylochidae. Consequently, type material of other stylochids deposited in the museums of Hamburg, Vienna, and Stockholm was borrowed to investigate the genital organs and, in particular, the interior lining of the prostatic vesicle. Based on these analyses, two new types of prostatic lining are defined, the polyglandular type and the monoglandular type. The monoglandular type is defined as having an oval to elongate prostatic vesicle with tubular lining and extra‐vesicular glands. Each extra‐vesicular gland is connected via a glandular duct with a single tube. The polyglandular type is defined as having a mostly roundish oval prostatic vesicle with long‐fingered extensions, more or less horizontally directed distad, and numerous extra‐vesicular glands. Each long‐fingered extension is connected via several glandular ducts of extra‐vesicular glands. Based on these new characters, the family Stylochidae is newly defined.     

商业路线价深度修正系数表编制中平均深度百分率法的应用

商业路线价深度修正系数表的编制一直以来就存在很大的主观性和随意性，这使编制出的修正系数表与实际相差很大，在实际工作中也没有实用性，本文总结实际工作中的一点经验，提出在商业路线坐深度修正系数表编制中运用平均深度百分率法，以期共同探讨。     

Judgemental revision of sales forecasts: The relative performance of judgementally revised versus non-revised forecasts

The judgemental revision of sales forecasts is an issue which is receiving increasing attention in the forecasting literature. This paper compares the performance of forecasts after revision by managers with that of the forecasts which were accepted by them without revision. The data set consists of sales forecasting data from an industrial company, spanning six quarterly periods and relating to some 900 individual products. The findings show that, in general, the improvements made by managers bring the forecast errors of revised forecasts more into line with non-revised forecasts, but the change is often marginal, and the best result is equivalence between revised and non-revised forecasts.
