    Sammanfattning : Historical demographic research is central to understanding past human behaviours and traits, such as fertility, mortality and migration. An essential part of historical demography is conducting longitudinal analyses at the micro-level, which involves the detailed follow-up of individuals over long time periods throughout their lives.

    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Sammanfattning : In industrial settings, machines such as trucks, hydraulic pumps, etc. are widely distributed at different geographic locations where sensors on machines produce large volumes of data. The data produced is stored locally in autonomous databases called log databases. LÄS MER

  4. 4. PERFORMANCE VISUALIZATION OF URBAN SYSTEMS

    Författare :Tim Johansson; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion;

    Sammanfattning : The planning, construction, management and use of our built environment are affected by diverse social, economic and environmental factors. Sustainable urban development is dependent on the understanding of the complex relations between the built environment, the social activities that take place over time and the interaction with the natural environment.

  5. 5. Spatial Analysis and Modeling for Health Applications

    Författare :Lars Skog; Yifang Ban; Matthew Smallman-Raynor; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Sweden; spatial analysis; spatial modeling; spatio-temporal spread; epidemiology; pandemic; walkability; health; Russian influenza; Asian influenza; A H1N1 pdm09; GWM; climate factors;

    Sammanfattning : Despite the benefits of applying methods of geographic information science (GIScience), the use of such methods in health service planning and provision remains greatly underutilized. Spread of epidemic diseases is a constant threat to mankind and the globalization of the world increases the risk for global attacks from multi-resistant bacteria or deadly virus strains. LÄS MER
