PSO优化多核RVM的模拟电路故障预测

针对模拟电路健康管理的特点，提出了一种基于PSO优化多核RVM的模拟电路故障预测方法。利用参数分析得到电路的输出频域响应作为特征，计算其与电路无故障标准响应的欧氏距离来表征电路元件健康值，将多个核函数线性组合，并用PSO优化多核RVM参数后的模型实现对各个时间点元件的健康值变化轨迹进行预测。仿真结果表明，该方法在小样本情况下，预测效果优于单一核函数的RVM模型，适用于健康管理中实时预测，具有较好的实用性。     

Semantic content-based image retrieval: A comprehensive study

The complexity of multimedia contents is significantly increasing in the current digital world. This yields an exigent demand for developing highly effective retrieval systems to satisfy human needs. Recently, extensive research efforts have been presented and conducted in the field of content-based image retrieval (CBIR). The majority of these efforts have been concentrated on reducing the semantic gap that exists between low-level image features represented by digital machines and the profusion of high-level human perception used to perceive images. Based on the growing research in the recent years, this paper provides a comprehensive review on the state-of-the-art in the field of CBIR. Additionally, this study presents a detailed overview of the CBIR framework and improvements achieved; including image preprocessing, feature extraction and indexing, system learning, benchmarking datasets, similarity matching, relevance feedback, performance evaluation, and visualization. Finally, promising research trends, challenges, and our insights are provided to inspire further research efforts.

让环境融入设计用心灵感受自然——克里斯多夫·英恩霍文及其合伙人事务所作品解读

可持续发展的建筑设计的核心不是简单的技术上的节能、环保,而是更深层次对自然的尊重和对人性的关怀。生态技术已经从物理人性化发展到生理、心理人性化的阶段。在设计实践中,我们应当把更多的时间和精力用于研究隐藏在形式背后的(文化上的和技术上的)更深层的内涵,研究设计与生活的关系。     

人性视角下的城市形象建设——以济南为例

目前，我国的城市正进入高速发展时期，城市形象建设也成为打造城市品牌、寻求城市特色的主要手段之一。然而，受传统的城市规划理论与技术所限，以及缺乏人性关怀等的原因，我国的城市形象建设存在盲目攀高、过分追求“新、特、奇”等现象，城市的原有个性和特色逐渐消失。应从人性角度出发，注重发掘城市的景观特质，创造丰富多变、富有人情味的城市景观，以满足人们日益丰富、多元化的需求，塑造与众不同的城市形象。     

改进相关反馈技术在CBVR人体动作识别中的应用研究

针对CBVR人体动作识别问题,提出利用相关反馈技术与其它技术相结合。首先,分析了从视频中提取人类行为并将其表示成特征集的方法;然后研究了各种基于内容的视频检索方法;最后,将这些技术进行组合得到基于相关反馈技术的最优CBVR人体动作识别方法。在三个行为数据库中(包括UCF运动,UCF视频网站和HOHA2)评估了由上述几种技术组合而成的性能,实验结果为开发高效的基于内容的视频检索系统提供了有益的借鉴。     

Viewpoint: Information systems research strategy

This article^1,2 has two aligned aims: (i) to espouse the value of a strategic research orientation for the Information Systems Discipline; and (ii) to facilitate such a strategic orientation by recognising the value of programmatic research and promoting the publication of such work. It commences from the viewpoint that Information Systems (IS) research benefits from being strategic at every level, from individual researcher, to research program, to research discipline and beyond. It particularly advocates for more coordinated programs of research emphasising real-world impact, while recognising that vibrant, individual-driven and small-team research within broad areas of promise, is expected to continue forming the core of the IS research ecosystem. Thus, the overarching aim is the amplification of strategic thinking in IS research – the further leveraging of an orientation natural to the JSIS community, with emphasis on research programs as a main strategic lever, and further considering how JSIS can be instrumental in this aim.
