    Sammanfattning : The presence of computer technologies in our daily life is growing by leaps and bounds. One of the recent trends is the use of mobile technologies and cloud services for supporting everyday tasks and the sharing of information between users. LÄS MER

  3. 2. Managing uncertainties through efficient calculation of transients and harmonic propagation in power systems

    Författare :Oscar Lennerhag; Math Bollen; Jan Lundquist; David Thomas; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Overvoltages; harmonics; uncertainties; stochastic methods; Electric Power Engineering; Elkraftteknik;

    Sammanfattning : The electric power system is undergoing changes including large-scale introduction of renewable energy sources together with HVDC/FACTS, changes in the network such as increased amount of high voltage cables, industrial electrification, and changes in the load composition. These changes will impact the system in different ways and lead to challenges that must be addressed to facilitate planning, dimensioning, and operation of the system in a secure and economical way.

  4. 3. Pathways to future cropland : Assessing uncertainties in socio-economic processes by applying a global land-use model

    Författare :Kerstin Engstrom; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; land-use and land cover change; socio-economic modelling; scenarios; uncertainties;

    Sammanfattning : Global agricultural production almost tripled within the last five decades. The production increase wasbased on expanding cropland and pastures, as well as the intensification of agriculture, including increased use ofhigh yielding crop varieties, machinery, irrigation, artificial fertilisers, and pesticides.

  5. 4. Are uncertain uncertainties useful? : towards improved quality assessment of spatial data

    Författare :Britt-Inger Rönnbäck; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture; Arkitektur;

    Sammanfattning : A decision is usually based on some kind of information. In the decision- taking phase it is important to know the extent to which the information about the different alternatives that are to be decided on is reliable. LÄS MER

  7. 5. INDIVIDUAL GENETIC RESEARCH RESULTS : Uncertainties, Conceptions, and Preferences

    Författare :Jennifer Viberg Johansson; M G Hansson; Pär Segerdahl; Sophie Langenskiöld; Marion McAllister; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Incidental findings; genetic risk information; research participants; risk perception; free choice; framing; conceptions of genetic risk; making sense of genetic risk; preferences for genetic risk information;

    Sammanfattning : This thesis contributes to the ethical discussion on how to handle incidental findings in biomedical research using sequencing technologies from a theoretical and an empirical perspective. Study I and II are theoretical studies that used conceptual analysis. LÄS MER
