An analysis of transport phenomena for multi-solid particle systems at higher reynolds numbers by a standard karman—pohlhausen method—I Momentum transfer

Using the concentric spheres free surface model and a standard 4th polynomial Karman—Pohlansen method, the dimensionless tangential stress distribution, and the dimensionless pressure distribution around a solid sphere in a swarm, and the viscous, form and total drag coefficient for multi-solid particle systems were computed numerically at higher Reynolds numbers. The void function obtained from the drag coefficient for multiparticle system was comparative to the experimental data. The friction factor for multi-particle systems so computed agreed with the experimental data of packed and distended beds.     

No More Stopping

The dissolution of the conventional breaking points in the construction and completion phases of a building's delivery has blurred ‘the distinction between the production of design intent and the transmission of information’. Here Richard Garber , Director of the School of Architecture at the New Jersey Institute of Technology (NJIT), advocates that architects should use this as an opportunity to widen their remit, gaining agency and with it responsibility and the financial rewards to practice. Here he draws from the examples of UNStudio, GLUCK+ and his own New-York based practice, GRO Architects.     

天津港和横滨港发展环境及开发利用比较研究

天津港和横滨港皆以建设现代化国际港口为目标,但其发展条件、产业特征、发展理念和所处的发展阶段存在诸多差异.本文通过对上述两港的区位、自然条件、政策支撑等对外发展环境以及土地利用、功能布局、产业发展等对内开发利用两方面进行比较,总结了横滨港口发展的经验,以期为天津港未来的发展提供可供参考的借鉴.     

Type? What Type? Further Reflections on the Extended Threshold

Michael Hensel draws a parallel between the present and a moment in the early 1990s when typology seemed poised to come to the fore. He highlights how despite a promising start this interest slipped away and was supplanted by an obsession with topography and highly complex surfaces, leading to a primacy of the individual built form over the urban.     

Site/Non-Site: Extending the Parameters in Contemporary Landscape

As the world teeters on the verge of environmental collapse, landscape architecture has taken on a new significance offering a longed-for sanctuary for our increasingly urbanised lives. Here, in his introduction to the issue, guest-editor Michael Spens explains how by taking its impetus from land art, landscape architecture, as an expanded field, transcends the conventional confines of site. This renders it possible to read architecture ‘as landscape, or as non-landscape, as building becomes non-site’ and the ‘site indeed materialises as the work per se’.

The Wastewater Disposal System of the City of Yokohama, Japan

Modern sewerage system construction in the City of Yokohama dates from 1950. During the ensuing years, the City actively promoted such construction. The first sewage-treatment plant was commissioned in 1962, and the City's percentage of sewered population (including treatment services) reached 85% in March 1990.
This paper describes the outstanding development and record of the wastewater disposal system in Yokohama (which must be ranked ahead of other Japanese cities in this area), as well as the organization, technology, administrative and financing efforts that made this development possible. It also explains the notable features of these works, which include Japan's first fully-fledged centralized sludge treatment, improvement of combined sewerage systems, industrial effluent control, effective use of sewage effluent and sludge, and sewer user charges. In addition, it presents comments on the future tasks for the 21st century, including advanced wastewater treatment and the integrated information system on water environment.     

A Field Guide to Radical Post-Modernism

Sean Griffiths, Charles Holland and Sam Jacob of FAT curate and classify the work of a diverse and international grouping of Radical Post-Modern architects. They range from the recently defunct Foreign Office Architects (FOA), known for their proclivity for pattern and ornament, to Tokyo-based Atelier Bow-Wow who are rigorous in their pursuit of the ordinary. They run the gamut of the highly figurative, as exemplified by Melbourne-based practice ARM, to the expressive austerity of Swiss architect Valerio Olgiati.

An analysis of transport phenomena for multi-solid particle systems at higher reynolds numbers by a standard Karman—Pohlhausen method—I Mass transfer

Using the velocity profiles, based on the concentric spheres free surface model and a standard 4th polynomial Karman—Pohlhausen method in Part 1, the diffusion equation was solved numerically at higher Reynolds numbers. The mass transfer rate for multi-solid particle systems so computed agreed with the exprerimental data of single solid spheres, and packed and fluidized beds at higher Reynolds numbers.     

基于用户测评的导医助手语音交互设计研究

目的 通过研究门诊导医助手的交互程度、音调、性别对拟人化程度、有效性、满意度的影响,为未来导医场景及更多公共场合的语音助手的形象与话术设计提供参考。方法 让12位被试在模拟导医场景下与不同交互程度、音调、性别的语音助手进行对话任务,通过绿野仙踪测试法(Wizard of Oz)进行实验。使用七分李克特量表获取拟人化程度、有效性、满意度评分并进行开放性访谈,再通过弗里德曼检验(Friedman Test)、威尔克尔森符号秩检验(Wilcoxon Signed Rank Test)与最小二乘回归分析对结果进行量化分析,以探索用户对导医助手的形象与话术偏好。最后根据研究结果,对导医系统展开了多模态用户界面的设计实践。结果 在导医场景下,用户更偏好交互程度高的导医助手,音调为女低音或男高音的导医助手评分更高,用户对导医助手的性别没有明显偏好。导医助手的用户满意度随着拟人化程度的增加而增加。结论 对于公共场合的语音交互设计,应深入调研各类用户的偏好,设计出更受用户喜爱的语音助手,并发挥出多模态用户界面的优势。     

The Grand Work of Fiction: The Detail as Narrative

A practising architect and Professor at the University of Virginia School of Architecture, Edward Ford is the leading expert on the architectural detail and the author of three seminal books on the subject. Here Ford explains that, though the decision ‘to abstract or to articulate’ architecture ‘may be largely subconscious’, it is never ‘arbitrary’. For ‘in the well-designed building, it is done in the service of the creation of a larger narrative, a unity of vision’.
