Computation or Revolution

The connection between technology and society today remains as compelling as in Le Corbusier's time, with views from social commentators, scientists and economists habitually polarising around the adverse or positive impact of technological change. Tracing the roots of computation and robotics back to the Second World War, Philippe Morel of EZCT Architecture & Design Research redefines the position of artificial intelligence, robots and computation in architecture, highlighting the potential of computers to perform precise calculations – and outperform human intelligence in almost every way.

Integrating engineering design and analysis using a multi-representation approach

With the present gap between CAD and CAE, designers are often hindere in their efforts to explore design alternatives and ensure product robustness. This paper describes the multi-representation architecture (MRA)—a design-analysis integration strategy that views CAD-CAE integration as an information-intensive mapping between design models and analysis models. The MRA divides this mapping into subproblems using four information representations: solution method models (SMMs), analysis building blocks (ABBs), product models (PMs), and product model-based analysis models (PBAMs). A key distinction is the explicit representation of design-analysis associativity as PM-ABB idealization linkages that are contained in PBAMs.The MRA achieves flexibility by supporting different solution tools and design tools, and by accommodating analysis models of diverse discipline, complexity and solution method. Object and constraint graph techniques provide modularity and rich semantics.Priority has been given to the class of problems termedroutine analysis—the regular use of established analysis models in product design. Representative solder joint fatigue case studies demonstrate that the MRA enables highly automated routine analysis for mixed formula-based and finite element-based models. Accordingly, one can employ the MRA and associated methodology to create specialized CAE tools that utilize both design information and general purpose solution tools.Nomenclature MRA multi-representation architecture - SMM solution method model - ABB analysis building block - PM product model - PBAM product model-based analysis model - ABB-SMM transformation - idealization relation between design and analysis attributes - PM-ABB associativity linkage indicating usage of one or more _i eislab. eislab. gatech. edu.

真空滤油机在特高压南阳开关站高抗绝缘油处理中的改进

ABB滤油机在绝缘油处理过程中,为了防止分离器和冷凝器中的绝缘油溢出损坏真空泵,当达到极限油位时必须及时停机并加以清除,然后才能再次投入使用,这在一定程度上影响了绝缘油处理的效率。针对这一问题,对ABB滤油机进行了改进,在分离器和冷凝器下方加装小型泄油器,在分离器和冷凝器油位达到极限位置时通过泄油器及时排出,从而保证了滤油机工作的连续性,很好地解决了上述问题。通过1 000 kV南阳开关站高抗绝缘油滤油的实践检验,证明提出的ABB滤油机改进方法是可行的。
