城市家具中信息导视系统的设计

本文从强调城市家具不但具有家具的功能属性,还具有城市信息的传递和导视这一视觉属性的角度出发,论述了信息导视系统的合理化设计对城市家具在环境中视觉作用的影响。并具体从尺度、环境整体和互动结合等几个方面阐述了城市家具中导视系统设计的原则与方法。     

从汤匙到城市

意大利设计史学家罗杰斯认为,设计的每一个元素“从汤匙到城市”都同等重要。20世纪50年代,丹麦著名现代设计大师阿耐·雅各布森设计的丹麦皇家宾馆充分体现了“从汤匙到城市”的设计理念。     

Structural robustness of city road networks based on community

Road network robustness is the ability of a road network to operate correctly under a wide range of attacks. A structural robustness analysis can describe the survivability of a city road network that is under attack and can help improve functions such as urban planning and emergency response. In this paper, a novel approach is presented to quantitatively evaluate road network robustness based on the community structure derived from a city road network, in which communities refer to those densely connected subsets of nodes that are sparsely linked to the remaining network. First, a road network is reconstructed into a set of connected communities. Then, successive simulated attacks are conducted on the reconstructed road networks to test the performance of the networks under attack. The performance of the networks is represented by efficiency and the occurrence of fragmentation. Three attack strategies, including a random attack and two intentional attacks, are performed to evaluate the survivability of the road network under different situations. Contrary to the traditional road segment-based approach, the community-based robustness analysis on a city road network shows distinct structural diversity between communities, providing greater insight into network vulnerability under intentional attacks. Six typical city road networks on three different continents are used to demonstrate the proposed approach. The evaluation results reveal an important feature of the structure of city road networks from a community-based perspective, i.e., that the structure is robust under random failure but fragile under intentional attack. This result is highly consistent in different city road network forms.     

关于“理想城市”的几点感知

在未来的20年,世界城市将以史无前例的速度和规模迅猛扩张。其中正在崛起的亚洲地区,特别是中印两国被认为是最典型的案例。交通拥堵,环境污染,房价飞腾,健康危害,安全弱化,文化丧失等问题造就了多种多样的城市病,离开了人,城市就不付存在。城市的所有问题都是由人而引发,中国城市最缺的不是知识、历史、也不是硬件的基础建设,而是城...     

An edge-based platform for dynamic Smart City applications

A Smart City is a cyber–physical system improving urban behavior and capabilities by providing ICT-based functionalities. An infrastructure for Smart City has to be geographically and functionally extensible, as it requires both to grow up with the physical environment and to meet the increasing in needs and demands of city users/inhabitants. In this paper, we propose iSapiens, an IoT-based platform for the development of general cyber–physical systems suitable for the design and implementation of smart city services and applications. As distinguishing features, the iSapiens platform implements the edge computing paradigm through both the exploitation of the agent metaphor and a distributed network of computing nodes directly scattered in the urban environment. The platform promotes the dynamic deployment of new computing nodes as well as software agents for addressing geographical and functional extensibility. iSapiens provides a set of abstractions suitable to hide the heterogeneity of the physical sensing/actuator devices embedded in the system, and to support the development of complex applications. The paper also furnishes a set of methodological guidelines exploitable for the design and implementation of smart city applications by properly using iSapiens. As a significant case study, the design and implementation of a real Smart Street in the city of Cosenza (Italy) are shown, which provides decentralized urban intelligence services to citizens.
