研究了基于深度强化学习算法的自主式水下航行器(AUV)深度控制问题。区别于传统的控制算法,深度强化学习方法让航行器自主学习控制律,避免人工建立精确模型和设计控制律。采用深度确定性策略梯度方法设计了actor与critic两种神经网络。actor神经网络给出控制策略,critic神经网络用于评估该策略,AUV的深度控制可以通过训练这两个神经网络实现。在OpenAI Gym平台上仿真验证了算法的有效性。

A practical approach to meeting national obligations for sustainable trade under CITES
Abstract Reconciling conservation goals with sustainable resource use requires adaptive management strategies. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) regulates global trade for species listed on Appendix II, partly by requiring member countries (parties) to ensure exports do not damage wild ...

Abstract Content moderation comes with trade‐offs and moral dilemmas, particularly for transnational platforms governing borderline content where the boundaries of acceptability are subject to debate. While extensive research has explored the legality and legitimacy of platformised speech governance in established democracies, few address the ...

通过对激光外调制不同方式的对比分析,重点研究了AOM(声光调制)器件的原理及控制方法,提出了三种可控调制方法,且在控制方面分别进行了对比验证。采用其中的TTL电平(典型值高电平3.5V,低电平0.2V)调控方法,将数字信号经FPGA(现场可编程门阵列)以2FSK(二进制移频键控)方式进行调制编码,调制信号通过AOM加载于激光上,激光通过自由空间传输,借助串口实现了通信速率为115.2kbit/s的数字通信,且该激光外调制通信系统高频载波达到了0.7MHz左右。

Abstract The consumption of harmful commodities drives the noncommunicable disease (NCD) epidemic globally and in Pacific small island developing states. Multisectoral committees are commonly chosen avenues to facilitate policy coherence across government sectors in regulating the commercial determinants of health (CDoH), but these committees often ...

Abstract Prior research in health equity, including food security, indicates that disadvantaged groups, such as women with limited resources, face many obstacles in achieving food security. One of the first of its kind to draw on intersectionality and the social determinants of health frameworks, this study identified and tested gender differences in ...

Potholes, 311 reports, and a theory of heterogeneous resident demand for city services
Abstract Understanding the needs of residents is vital in public administration and management, as this helps officials when making choices on policies and service distribution. Increasingly, cities rely on 311 systems to elicit information from residents on emergent needs in particular policy areas (e.g., road quality, pest control).

Abstract Whether and how remitted clinical depression in postpartum motherhood contributes to poor infant adaptive functioning is inconclusive. The present longitudinal study examines adaptive functioning in infants of mothers diagnosed as clinically depressed at 5 months but remitted at 15 and 24 months. Fifty‐five U. S.
