  1. 1. Design challenges of privacy controls for IoT systems

    Författare :Tomasz Kosinski; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internet of Things IoT ; usable privacy and security; voice assistants;

    Sammanfattning : The Internet of Things (IoT), based on single-purpose internet-connected devices, becomes more and more pervasive. It is increasingly adopted by private households and hospitality industry, providing services such as security, monitoring or voice assistance via the "cloud". LÄS MER

  2. 2. Comparative Assessment of Fuel-Based Systems for Space Heating

    Författare :Åsa Karlsson; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; Energy research; cogeneration; district heating; electric heating; external cost; carbon dioxide mitigation; detached houses; fossil fuels; Energy systems; bioenergy;

    Sammanfattning : Replacing fossil fuels by biofuels and increasing energy efficiency are often considered to be options for reducing the net emission of greenhouse gases. This thesis presents the results of analyses of energy efficiency, emission and cost of whole energy system chains, from the natural resource to the end user when heating detached houses in a Swedish context.

  3. 3. Cognitive and Self-Adaptive SoCs with Self-Healing Run-Time-Reconfigurable RecoBlocks

    Författare :Byron Navas; Ingo Sander; Johnny Öberg; Michael Hübner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In contrast to classical Field-Programmable Gate Arrays (FPGAs), partial and run-time reconfigurable (RTR) FPGAs can selectively reconfigure partitions of its hardware almost immediately while it is still powered and operative. In this way, RTR FPGAs combine the flexibility of software with the high efficiency of hardware. LÄS MER

  4. 4. Complex methods of inquiry: structuring uncertainty

    Författare :PETER BEDNAR; Institutionen för informatik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; information system; Contextual Analysis; Contextual Dependencies; Systems Approaches; Systems Thinking; Organizational change; Complex adaptive systems; Uncertainty management; Organizational Emergence; Change Management; Organizational Learning; Human Activity Systems;

    Sammanfattning : Organizational problem spaces can be viewed as complex, uncertain and ambiguous. They can also be understood as open problem spaces. As such, any engagement with them, and any effort to intervene in order to pursue desirable change, cannot be assumed to be just a matter of ‘complicatedness’. LÄS MER

  5. 5. Development and evaluation of methods for control and modelling of multiple-input multiple-output systems

    Författare :Fredrik Bengtsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Input-output scaling; Modeling; Fiber length; Tensile Index; Hold-input; Decentralized control; Gramian based measures; Delays; LQG control; TMP; Uncertain data sets; Unreliable communication links; MIMO systems; Control configuration selection; Linear regression; Freeness; Shives; CTMP;

    Sammanfattning : In control, a common type of system is the multiple-input multiple-output (MIMO) system, where the same input may affect multiple outputs, or conversely, the same output is affected by multiple inputs. In this thesis two methods for controlling MIMO systems are examined, namely linear quadratic Gaussian (LQG) control and decentralized control, and some of the difficulties associated with them.
