Empirical Findings from an Ascending Stair Evacuation Exercise in a Subway Station

Crowd simulations have proven to be a valuable numerical tool for evacuation analysis. There is series of research and empirical evacuation studies for infrastructures and buildings. In contrast to research on evacuation via descending stairs, little attention has been given to ascending stairs, but they are an important criterion, especially in subway stations with high passenger frequencies. In this paper, we present the findings from an evacuation exercise in a subway station with long ascending stairs. The empirical findings showed an increasing walking time on the ascending stairs during evacuation. Also, the flow rate differs with higher flow rates at the beginning of the stairs and lower values at the end of the stairs. The mechanism behind these results has still to be investigated, but the findings already provide an interesting basis for modelling and validating evacuation simulations over long ascending stairs

Integrated Simulation-based Framework for Parametric Open Space Design with Focus on Sustainable Mobility and Climate Resilience

Recent advances in the application of computational design show great potential in the holistic assessment of design scenarios. To tackle the challenges of climate change and urbanisation, we need intelligent planning methods to design sustainable urban development and resilient open spaces. Therefore, this paper presents an integrated simulation-based framework for parametric urban design with focus on sustainable mobility and climate resilience. Precisely, aspects from mobility, water management and microclimate are used for the evaluation of open space planning. The result is the framework including interfaces and the exemplary application to real-world scenarios in Aspern at Nelson Mandela Square

Homogeneous and heterogeneous catalysts for multicomponent reactions

[EN] Organic synthesis performed through multicomponent reactions is an attractive area of research in organic chemistry. Multicomponent reactions involve more than two starting reagents that couple in an exclusive ordered mode under the same reaction conditions to form a single product which contains the essential parts of the starting materials. Multicomponent reactions are powerful tools in modern drug discovery processes, because they are an important source of molecular diversity, allowing rapid, automated and high throughput generation of organic compounds. This review aims to illustrate progress in a large variety of catalyzed multicomponent reactions performed with acid, base and metal heterogeneous and homogeneous catalysts. Within each type of multicomponent approach, relevant products that can be obtained and their interest for industrial applications are presented.The authors wish to gratefully acknowledge the Generalitat Valenciana for the financial support in the project CONSOLIDER-INGENIO 2010 (CSD2009-00050)Climent Olmedo, MJ.; Corma Canós, A.; Iborra Chornet, S.

Mind the gap: Boarding and alighting processes using the social force paradigm calibrated on experimental data

Rudloff C, Bauer D, Matyus T, Seer S. Mind the gap: Boarding and alighting processes using the social force paradigm calibrated on experimental data. In: 14th International IEEE Conference on Intelligent Transportation Systems (ITSC). Piscataway, NJ: IEEE; 2011: 353-358.One of the few possibilities to increase the capacity of train lines is to make boarding and alighting more efficient. So far expensive experiments were needed to evaluate the effect of proposed changes to the train setup. This paper shows that a simulation model based on the social force paradigm and calibrated on measured data promises that in future simulations could be used to test new scenarios in a cheap and fast way
