举办大型运动会与城市生态环境保护的探讨

研究采用实地考察、文献分析以及生态学、城市规划、环境保护基本原理等。通过研究大型运动会城市生态环境问题的产生、特点和表现，提出举办大型运动会与城市生态环境保护协调措施。认为，大型运动会引起城市生态环境的问题主要表现在：(1)体育场馆设施建设；(2)建材的使用与废弃；(3)城市环境污染；(4)场馆设施与交通能源利用；(5)体育场馆设施赛后利用等。在举办大型运动会中，要确保城市生态环境的可持续发展，一是制定大型运动会城市生态环境保护具体规划，二是促进公众参与，加强城市环境治理。

基于深度强化学习方法的无线多跳网络能量高效机会路由

由于机会路由能够利用无线信道的广播特性和有损特性,因此一直是提高无线网络路由性能的一个很有效的途径。提出一种基于深度强化学习的无线多跳网络能量高效机会路由算法,该算法使得智能体能够通过训练学习最优的路由策略,以通过机会路由的方式减少传输时间,同时平衡能耗延长网络寿命。此外,本算法还可以极大地缓解冷启动问题并获得较好的初始性能。仿真结果表明,与现有算法相比,该算法具有更好的性能。     

The Future of the Past: Archaeology and Anthropology on the World Wide Web

In the final scene of Raiders of the Lost Ark, a crate containing the object of Indiana Jones' quest is wheeled into an immense warehouse for indefinite storage and questionable research access. Unfortunately, this fate is not all that far from reality. Collections of archaeological and ethnographic materials ranging from stone axes, broken potsherds, and carved monuments to baskets, ceremonial masks, and skin canoes have been held by museums collections since the Renaissance. However, their inestimable value and unique conservation and curatorial requirements often conspire to remove them from the reach of all but the most diligent scholars. The potential of the Web to enhance the quality of research on archaeological and ethnographic collections is enormous. This paper will examine ways that one can use the Web to enhance research and improve access to a variety of materials; while there are many other resources for archaeology available on the Web, this paper focusses on museum-related sites. It will also explore the potential of the Web for innovative research strategies. Digitization of catalogs, associated documents, and images to help one locate and study collections and specific artifacts are just one approach. Others include the connection of devices to the Web, such as cameras and microscopes, the creation of virtual reference collections, and the establishment of research networks that will enhance the identification and analysis of material culture. This paper will also consider the role the Web could play in issues of cultural property, contributing to and in many ways intensifying ongoing debates of ownership, curation, conservation, and repatriation of sensitive materials.     

基于概率神经网络的文本自动分类研究

本文提出了将一种径向基网络的重要变形———概率神经网络应用于文本自动分类的研究 ,与常用的K 最邻近法相比 ,具有一定的优势 ,特别是在训练集中各类的训练样本数很不平衡时 ;与BP等其他神经网络相比 ,其特点是需调节的参数少 ,不需确定隐层数、隐层中的神经元数量等网络结构 ,比较容易使用。此外 ,从研究中的不同特征选择的评价函数来看 ,它们对分类有一定的影响 ,应用X2 统计进行特征选择的分类正确率最高 ,其次是文本证据权 ,而期望交叉熵的效果最差 ,说明特征选择在文本自动分类中也是非常重要的。

Update: The Invisible Farmer: securing Australian farm women’s history

This article reviews the Invisible Farmer project – the largest study of Australian women on the land – a third of the way through its three year funding period. It introduces the aims of this collaborative and multidisciplinary project, focusing on the role of records and oral histories in the creation of new narratives, and the task of raising public awareness of the important historical and contemporary contributions made by Australian women farmers. We examine the way digital platforms work to curate records and promote research, and outline the important role that the Australian Women’s Register, a core project of the Australian Women’s Archives Project, will play in achieving outcomes.
