  2. 1. Spatial analysis and modeling of urban transportation networks

    Author : Jingyi Lin; Yifang Ban; Sten Henning Hansen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complex networks; transportation systems; network growth; Evolving networks; centrality; urban systems; topology; space syntax; spatial networks; distance effects; gravity laws; planarity; street network patterns; US airline system; China’s aviation system; network efficiency; cellular structure; hierarchy; network representations; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Abstract : Transport systems in general, and urban transportation systems in particular, are the backbone of a country or a city, therefore play an intrinsic role in the socio-economic development. There have been numerous studies on real transportation systems from multiple fileds, including geography, urban planning, and engineering. READ MORE

    Author : Rajib Sinha; Björn Frostell; Maria Malmström; Miguel Brandao; Mujibur Rahman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complex systems modeling; environmental accounting and monitoring; en- vironmental footprint; industrial ecology; pressure-based driver-oriented approach; Modellering av komplexa system; miljöräkenskaper och miljöövervakning; miljöpåverkan; industriell ekologi; flödesbaserad övervakningaktörsorienterad strategi; Industrial Ecology; Industriell ekologi;

    Abstract : Many of the present problems that we are facing arise as unanticipated side-effects of our own actions. Moreover, the solutions implemented to solve important problems often create new problems. To avoid unintended consequences, understanding complex systems is essential in devising policy instruments and in improving environmental management. READ MORE

  6. 4. On intelligent automation systems

    Author : Endre Erös; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automated planning; Automation; testing and coverability.; modeling; virtual preparation and commissioning; robot operating system;

    Abstract : Developing automation systems that are capable of handling dynamic and unpredictable situations is a challenging task, as it requires adapting to a changing environment and managing potentially unforeseen action outcomes. In contrast to traditional automation, where control code is explicitly pro- grammed, a model-based approach might be a more appropriate solution for automating such systems. READ MORE

    Abstract : The production and consumption of information and communication technology (ICT) products and services continue to grow worldwide. This trend is accompanied by a corresponding increase in electricity use by ICT, as well as direct environmental impacts of the technology. Yet a more complicated picture of ICT’s effects is emerging. READ MORE
