  2. 1. Systems Modeling Approaches to Physical Resource Management : An Industrial Ecology Perspective

    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

  4. 2. ForSyDe-Atom: Design of Heterogeneous Embedded Systems : Taming Complexity with Layers, Atoms and Patterns

    Author : George Ungureanu; Ingo Sander; Reinhard von Hanxleden; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; system design languages; modeling; simulation; synthesis; embedded systems; cyber-physical systems; domain specific languages; systemdesignspråk; modellering; simulering; syntes; inbyggda system; cyberfysiska system; domänspecifika språk; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : The design of embedded systems is inherently complex for two main reasons. Firstly, it entails the combined knowledge and results from a vast set of mature, well-established, yet separate disciplines, such as electrical engineering, computer science, mechanical engineering, etc. READ MORE

  5. 3. Industrial Ecology Approaches to Improve Metal Management : Three Modeling Experiments

    Author : Rajib Sinha; Björn Frostell; Maria Malmström; Amir Rashid; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system dynamics; element flow analysis; industrial ecology; product systems; end-of-life; DPSIR; pressure-based driver-oriented approach; environmental management; Industrial Ecology; Industriell ekologi;

    Abstract : A linear model of consumption − produce-use-dispose − has constantly increased the pressure on the environment in recent decades. There has been a great belief that technology will solve the problem, but in many cases it is only partly contributing to the solution. For a full solution, the root causes of problems need to be identified. 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

  7. 5. Prediction of Mobile Radio Channels : Modeling and Design

    Author : Torbjörn Ekman; Rodney Vaughan; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systemteknik; mobile radio channel; fading; channel model; channel estimation; channel prediction; power prediction; Systemteknik; Systems engineering; Systemteknik; Signal Processing; signalbehandling;

    Abstract : Prediction of the rapidly fading envelope of a mobile radio channel enables a number of capacity improving techniques like fast resource allocation and fast link adaptation. This thesis deals with linear prediction of the complex impulse response of a channel and unbiased quadratic prediction of the power. READ MORE
