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

    Författare :Rajib Sinha; Björn Frostell; Maria Malmström; Amir Rashid; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Miniaturised Microwell-based Cell Assays

    Författare :Emilie Weibull; Helene Andersson Svahn; Albert van den Berg; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microwell; miniaturisation; high-resolution imaging; high-throughput; cell culture; single-cell; clone; heterogeneity; antibiotic susceptibility testing; concentration gradient; interfacing; microchannels; cell retrieval;

    Sammanfattning : Cell heterogeneity in genetically identical cell populations is becoming a well-known and important phenomenon in cell biology. Current methods commonly utilise population-based analysis founded on averaged result. Hence there is a need for high-throughput cell assays on the single-cell level. LÄS MER

  4. 3. Towards Correct and Efficient Program Execution in Decentralized Networks: Programming Languages, Semantics, and Resource Management

    Författare :Karl Palmskog; Mads Dam; Rocco De Nicola; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; distributed objects; decentralization; implementation correctness; network protocols; object mobility; Computer Science; Datalogi;

    Sammanfattning : The Internet as of 2014 connects billions of devices, and is expected to connect tens of billions by 2020. To meet escalating requirements, networks must be scalable, easy to manage, and be able to efficiently execute programs and disseminate data. The prevailing use of centralized systems and control in, e.g. LÄS MER

  5. 4. Entrepreneurship at the limits

    Författare :Lena Olaison; Daniel Hjorth; Bent Meier Sørensen; Denmark Copenhagen Business School; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ledarskap; entreprenörskap och organisation; Ledarskap; entreprenörskap och organisation;

    Sammanfattning : This PhD dissertation is based on four published articles. It operates within the processual view of entrepreneurship studies (Steyaert, 1997), which draws on process philosophy to develop research strategies (Sørensen, 2005). The research has been guided by two strategies for understanding entrepreneurship: ‘moving’ (e.g. LÄS MER

  7. 5. Horizontal Slot Waveguides for Silicon Photonics Back-End Integration

    Författare :Maziar A. M. Naiini; Mikael Östling; Jörge Schulze; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon photonics; slot waveguides; grating couplers; CMOS tech- nology; high-k; ALD; germanium photodetectors; graphene photodetectors; pho- tonic integrated circuits;

    Sammanfattning : This thesis presents the development of integrated silicon photonic devices. These devices are compatible with the present and near future CMOS technology. High-khorizontal grating couplers and waveguides are proposed. LÄS MER
