中国建筑话语中的“文脉”(1980年代-1990年代)

对"文脉"一词进入中国建筑话语的历史作出概览式的回顾,并分别以"阙里宾舍"和"西单商业大楼"为例,从设计者的自述与建筑界的评论入手,探讨1980年代末到1990年代初"文脉热"兴起的可能原因。指出对"复古主义"的批判和创作有"民族特色"建筑的愿望是"文脉"一词背后潜在的诉求,同时,也警醒地看到,基于特定时代背景,中国建筑界对西方后现代主义等建筑思潮不可避免地片面理解和吸收,也造成了"文脉"逐渐丧失了其本应具有的批判性与创造力。     

Extracting Low-Frequency Spatio-Temporal Patterns in Ambient Power System Data Using Blind Source Separation

Wide-area techniques provide a powerful tool to extract spatio-temporal patterns from high-dimensional datasets and can be used for event detection and visualization, data fusion, stability assessment, and coherency analysis. In this paper, a novel blind source separation-based approach for extracting low-frequency spatio-temporal patterns from measured ambient power system data is proposed and a spatio-temporal visualization index is also suggested. This methodology combines a nonlinear hierarchical neural network with a Blind Source Separation (BSS) technique. The neural network allows reducing noise and removing the nonlinear relations among data (preserve dynamic features of interest), while the BSS technique permits extracting spatial and temporal patterns. In addition, the proposed approach takes advantage of the latest techniques in nonlinear estimation of non-stationary time series. Finally, application examples of the proposed framework on real test cases recorded from an actual power system by Phasor Measurement Units (PMUs) are presented. The obtained results show that the temporal patterns can be used for extracting and identifying the low-frequency oscillation modes and the spatial patterns can be used for identifying modes with the most contribution in original data. Compared to other BSS approaches, the proposed method has shown to be better for the analysis of real ambient data.     

Generating video animation from single still image in social media based on intelligent computing

Bringing a single still image into reality is a challenging topic in computer animation because the driven and structural information in single still image is inadequate. In this paper, we present an image animating method for enhancing single still image in social media with virtual realistic and animated motions without prior information. We imitate the interaction between the active objects in an image and their neighboring passive objects. The existing actions in the image and the virtual specified force are employed to animate the active objects. Observing that the change between two subsequent motions of the active objects derives a motion tendency, we can calculate a virtual driving force based on the motion tendency. By virtue of the virtual driving force, the stochastic motion texture is used to animate the passive objects. Finally, the convolutional neural network is employed to optimize the virtual motion animations. In this way, the proposed method produces visually natural results while guaranteeing motion harmony between active objects and passive objects. To demonstrate the applicability and rationality of virtual animation driving force, our method generates several animations from still images in Social Media.

海宝山区滨江带开发设计构想

上海宝山区滨江带地理区位优越、历史文化底蕴深厚但土地利用空间结构较为分散、内部功能混杂。宝山区滨江带开发设计应强化其文化、休闲、娱乐、旅游、商务、航运功能,结合滨江区时尚住宅的开发和国际航运中心的建设,形成多方位展示都市风采的旅游风景带,同时,通过对滨水空间的功能、空间、景观、环境、设施等多方面所进行的综合性设计,创造生动、优美、富于特色的城市滨水空间形象,把宝山建设成为世界级的具有宝山特色的滨水胜地。

协调·突破──浅谈文化娱乐中心与城市的关系

文化娱乐中心不是孤立的建筑单体，而是城市的有机构成部分．其设计应从全局出发综合多种客观因素，不仅要考虑与人的关系还要研究与城市的总体关系从城市的硬件（公建设施、基础设施等）到软件（传统文脉、环境特性等）方面着手来进行规划设计，才能创造出与城市深深相融的具有个性的空间场所．本文通过理性分析和国内外一些实例来探讨中心与城市二者的互动关系。
