  1. 1. Epitaxy of group III-nitride materials using different nucleation schemes

    Författare :Rosalia Delgado Carrascon; Vanya Darakchieva; Daniela Gogova; Alice Hospodková; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Group III-nitride materials, gallium nitride (GaN), aluminum nitride (AlN) and indium nitride (InN) have direct band gaps with band gap energies ranging from the infrared (InN) to the ultraviolet (GaN) and to the deep ultraviolet (AlN) wave-lengths, covering the entire spectral range from 0.7 eV to 6.2 eV upon alloying.

  3. 2. System-Wide Impacts of Distributed Generation on Power System Operation : Data-Driven Approaches to Addressing the Challenges of Integrating Distributed Generation

    Författare :Tin Rabuzin; Lars Nordström; Marjan Popov; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; data-driven modelling; distributed generation; dynamic equivalencing; islanding detection; reduced order modelling; datadriven modellering; detektion av ödrift; distribuerad generation; dynamisk modellering; reducerad ordningsmodellering; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Deployment of distributed generation (DG) is happening at an increasing rate driven by both the need for the reduction of humanity's carbon footprint and economic opportunities. The trend of increasing penetration levels of DG has also introduced interdependence between the responsibilities of system operators and the owners of the generating units. LÄS MER

  4. 3. Energy systems studied of biogas : Generation aspects of renewable vehicle fuels in the transport system

    Författare :Mimmi Magnusson; Per Alvfors; Umberto Desideri; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; biogas; biomass; energy system; first-generation biofuels; renewable vehicle fuels; second-generation biofuels; supply- and demand-side measures; third-generation biofuels; transport system;

    Sammanfattning : The transport sector is seen as particularly problematic when concerns about climate change and dependency on fossil energy are discussed. Because of this, bioenergy is strongly promoted for use in the transport sector, both on a European level and nationally in Sweden. LÄS MER

  5. 4. Christianity, Generation and Narrative : Religious Conversion and Change in Sidama, Ethiopia, 1974–2012

    Författare :Erik Egeland; Magnus Lundberg; Kajsa Ahlstrand; Dena Freeman; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Christianity in Ethiopia; Conversion Narratives; Religious Change; Modernity; Social Generation; Sidama; SNNPRS; Southern Ethiopia; Missionsvetenskap; Studies of Missions;

    Sammanfattning : This study presents narratives concerning religious conversion and change in Evangelical-Pentecostal Christian communities in the Sidama zone, Southern Ethiopia. The study is based on narrative data collected through field research, which mainly focuses on the period 1974–2012. LÄS MER

  7. 5. Integrated Code Generation

    Författare :Mattias Eriksson; Christoph Kessler; Andreas Krall; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datalogi;

    Sammanfattning : Code generation in a compiler is commonly divided into several phases: instruction selection, scheduling, register allocation, spill code generation, and, in the case of clustered architectures, cluster assignment. These phases are interdependent; for instance, a decision in the instruction selection phase affects how an operation can be scheduled. LÄS MER
