边境棕地: 后工业及后冲突棕地景观

The Demilitarized Zone (DMZ) landscape between the Democratic People’s Republic of Korea and the Republic of Korea is currently the most dangerous and heavily fortified territory in the world and has produced a series of continuously linked brownfield lands on a divided Korean Peninsula through the continued intense presence of military troops and equipment, a significant amount of defense infrastructure, and pollutant buildup over the last seventy years. The political and social reunification of the two Koreas may occur in the coming years and any work in the future to address the landscape of a unified peninsula would be required to carry out in the DMZ. The work includes a complete characterization of the land area and water bodies and the existing military infrastructure and abandoned equipment, with the proposed remediation of soils, groundwater, and drainage systems as well as the concerns of brownfield land reuse, adding new industrial manufacturing to the area, the increase of tourism into the region, and the development of both traditional and new forms of regional energy generation. The brownfields in the DMZ can be considered an extreme version of the more conventional post-industrial sites that are addressed in other urban or ex-urban venues through the methods and conventions of brownfield regeneration. Or indeed it may become a new type of brownfield site — the “brownfield border” — with its own characterization, on-site pollutants, and methods to address its ongoing remediation and reuse programs. The intention of this paper is to examine the DMZ through a recent academic study carried out through a graduate design studio at Harvard University focused on the outcomes of unification on the Korean peninsula, the remediation of border landscapes as a new type of brownfield practice, and potential planning and design of alternative futures.     

Gehry Partners' Fondation Louis Vuitton: Crowdsourcing Embedded Intelligence

The complexity of the mass-customised forms of Gehry Partners' new art museum in Paris, the Fondation Louis Vuitton pour la création, has taken high-definition simulation techniques and embedded intelligence to a new level. Tobias Nolte and Andrew Witt of Gehry Technologies describe how the realisation of the Fondation required the development of a 3D concurrent design system that could synchronise hundreds of participants. This self-optimisation system has enabled both ‘intricate collaboration and unprecedented engineering’. The benefits have been far reaching, ranging from the detailing of tolerances to material constraints.     

Entrepreneurship in Architectural Robotics: The Simultaneity of Craft,Economics and Design

What do Odico Formwork Robotics, RoboFold, Machineous, ROB Technologies and GREYSHED share in common? They are all architectural robotics startups. Jelle Feringa , Chief Technology Officer at Odico, places the phenomenon of the architectural robotics entrepreneur in a historical and cultural context while highlighting the very practical role startups are poised to play in bridging the gap between academic research and industry, by providing the building industry with much needed new software tools.     

Functional reliability analysis of Safety Grade Decay Heat Removal System of Indian 500 MWe PFBR

Passive systems are increasingly deployed in nuclear industry with an objective of increasing reliability and safety of operations with reduced cost. Methods for assessing the reliability of thermal-hydraulic passive systems, that is systems with moving working fluid, address the issues in natural buoyancy-driven flow that could result in a failure to meet the design safety limits under accident scenarios. This is referred as design functional reliability. This paper presents the results of functional reliability analysis carried out for the passive Safety Grade Decay Heat Removal System (SGDHRS) of Indian Prototype Fast Breeder Reactor (PFBR). The analysis is carried out based on the overall approach reported in the Reliability Methods for Passive System (RMPS, European Commission) project. Functional failure probability is calculated using Monte-Carlo method and also with method of moments.
