    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lattice codes; mutual information; intensity modulation; noncoherent communications; Direct detection; sphere packing.; infrared communications; free-space optical communications; fiber-optical communications;

    Sammanfattning : With the growing popularity of social media services, e-commerce, and many other internet-based services, we are witnessing a rapid growth in the deployment of data centers and cloud computing platforms. As a result, the telecommunications industry has to continue providing additional network capacity to meet the increasing demand for bandwidth. LÄS MER

  3. 2. Fighting for Aid : Foreign Funding and Civil Conflict Intensity

    Författare :Daniel Strandow; Magnus Öberg; Michael G. Findley; Kristian Skrede Gleditsch; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Aid; foreign aid; foreign assistance; relief; humanitarian; conflict; civil war; civil conflict; geographic concentration; intra-state; violence; military; contest; low-intensity; guerrilla; irregular; conventional; decision theory; contest success function; geo-coding; geo-referencing; territorial control; propensity score; Africa; South of the Sahara; Peace and Conflict Research; Freds- och konfliktforskning;

    Sammanfattning : This dissertation focuses on the sub-national impact of foreign aid on civil conflicts by asking the question: How does foreign aid committed to contested areas affect the intensity of violence in those areas? The main theoretical contribution is to focus on how aid influences warring parties’ decisions to engage in contests over territorial control and how that in turn influences violence intensity. The study introduces two concepts: funding concentration and barriers to exploiting aid. LÄS MER

  4. 3. Extending MRI to the Quantification of Turbulence Intensity

    Författare :Petter Dyverfeldt; Tino Ebbers; Krishna Nayak; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence intensity; cardiovascular disease; blood flow; hemodynamics; magnetic resonance imaging; generalized phase-contrast MRI; turbulent flow; Medical technology; Medicinsk teknik; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : In cardiovascular medicine, the assessment of blood flow is fundamental to the understanding and detection of disease. Many pharmaceutical, interventional, and surgical treatments impact the flow. The primary purpose of the cardiovascular system is to drive, control and maintain blood flow to all parts of the body.

  5. 4. Nederbördsintensitet och andra faktorer som påverkar skyfallsskador

    Författare :Barbara Blumenthal; Lars Nyberg; Jonas Olsson; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; urban flood; rainfall intensity; insured flood loss; flood damage function; GIS; urban översvämning; nederbördsintensitet; försäkringsskador; skadefunktion; GIS; Risk- och Miljöstudier; Risk and Environmental Studies;

    Sammanfattning : I Sverige inträffar många skyfall och intensiva regn under sommarmånaderna. Det finns inga uppenbara geografiska mönster, vilket är en skillnad gentemot älv- eller sjööversvämningar där det vanligtvis är känt vilka områden som kan komma att översvämmas vid en viss vattennivå eller ett visst vattenflöde.

  7. 5. Economic growth, energy consumption and CO2 emissions in Sweden 1800-2000

    Författare :Astrid Kander; Ekonomisk-historiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy intensity; Environmental Kuznets Curve; relative price analyses; standard calculations; technical change; structural changes; energy quality factors; consumers surplus; Social and economic history; forest management; CO2 intensity; Ekonomisk och social historia;

    Sammanfattning : Large transformations of technologies have occurred in the Swedish economy during the last two centuries, resulting in higher income, better quality of products and changing composition of GDP. An agrarian society has given way to an industrial society and lately to a post-industrial phase. LÄS MER
