  1. 1. Pollen-based quantitative reconstruction of land-cover change in Europe from 11,500 years ago until present - A dataset suitable for climate modelling

    Författare :Anna-Kari Trondman; Marie-José Gaillard; Chris Caseldine; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pollen data; REVEALS model; model testing; land vegetation; land-cover; Holocene; Europe;

    Sammanfattning : The major objective of this thesis was to produce descriptions of the land vegetation-cover in Europe for selected time windows of the Holocene (6000, 3000, 500, 200, and 50 calendar years before present (BP=1950)) that can be used in climate modelling. Land vegetation is part of the climate system; its changes influence climate through biogeophysical and biogeochemical processes. LÄS MER

  3. 2. Efficient Means for Platform-Based Development – Emphasizing Integrated, Information-Rich System Models

    Författare :Stellan Gedell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; function-means model; product families; product model; design rationale; integral model; platform-based design; reuse; systems theory; complete; consistent; product development; configurable component;

    Sammanfattning : Competition in the automotive industry is fierce, which in recent years has been demonstrated by some of the companies’ struggle to survive. A significant challenge is posed by the market’s ever-increasing expectations of new and impressive products, while maintaining profitability. LÄS MER

  4. 3. Pollen productivity estimates and pollen-based reconstructions of Holocene vegetation cover in Northern and temperate China for climate modelling

    Författare :Furong Li; Marie-José Gaillard; Mary E. Edwards; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climate; pollen-vegetation relationships; relative pollen productivity; REVEALS model; anthropogenic land-cover change; Holocene; China; Paleoecology; Paleoekologi;

    Sammanfattning : Model projections of future climate change require that coupled climate-vegetation models are developed and validated, i.e. these models should be able to reproduce past climate and vegetation change. Records of pollen deposited in lake bottoms and peat bogs can provide the information needed to validate these models. LÄS MER

  5. 4. Simulations of Coastal Atmospheric Dynamics and Transport Processes

    Författare :Ragothaman Sundararajan; Dimitris Melas; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; coastal atmosphere; dynamics; transport; Lagrangian particle dispersion model; mesoscale model; turbulence; Geovetenskap; Earth sciences; Geovetenskap; Meteorology; meteorologi;

    Sammanfattning : The marine atmosphere can be highly variable in space and time, and the coastal terrain plays a crucial role in influencing its properties. These, in turn, determine the atmospheric transport in the coastal zone. LÄS MER

  7. 5. Model-Integrated Engineering of Smart Energy Distribution Systems

    Författare :Nikolai Galkin; Valeriy Vyatkin; Chen-Wei Yang; Tatiana Liakh; Joao Martins; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : Model-Based Systems Engineering (MBSE) is a method that is used to support analysis, design, independent verification, and validation inherent in the development of software and hardware systems. MBSE applications are present in many areas of our daily lives, including manufacturing, robotics, healthcare, automation, etc. LÄS MER
