  1. 1. Mapping Primary Production for the West African Sahel with Satellite Data

    Författare :Jonathan Seaquist; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical geography; Sahel; CENTURY; Monte Carlo; GPP; transpiration; LUE; CLAVR; PAR; compositing; MVC; geostatistics; noise; NDVI; NOAA AVHRR; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Sammanfattning : A light Use Efficiency (LUE) model is developed that allows the mapping of total growing season Gross Primary Production (GPP) for the West African Sahel, using the Normalized Difference Vegetation Index (NDVI) together with other data. Image quality may be poor in monthly NDVI maximum value composites as shown by an improved geostatistical noise estimation technique. LÄS MER

  3. 2. Evaluating Tropical Upper-tropospheric Water in Climate Models Using Satellite Data

    Författare :Marston Sheldon Johnston; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ECHAM6; Humidity; Climate; CAM5; IWC; Clouds; EC-Earth;

    Sammanfattning : Measuring and simulating moist processes in the tropical upper troposphere are difficult tasks. Humidity in this region of the atmosphere is mainly supplied by deep convection and, problems with simulated convection areknown to be a major contributor to uncertainties in climate model projections.

  4. 3. Towards a Multi-OS Architecture for Consistent User Interface Experience

    Författare :Tobias Holstein; Gordana Dodig-Crnkovic; Christian Berger; Elina Vartiainen; Manh Tien Tran; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : Vehicles have greatly changed over the last decades. Originally, they were used as a means of transportation, and their drivers were solely engaged in the driving task. In modern cars the user, i.e. LÄS MER

  5. 4. Upscaling Organic Electronic Devices

    Författare :Abdellah Malti; Xavier Crispin; Ananth Dodabalapur; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Conventional electronics based on silicon, germanium, or compounds of gallium require prohibitively expensive investments. A state-of-the-art microprocessor fabrication facility can cost up to $15 billion while using environmentally hazardous processes. LÄS MER

  7. 5. Level-set methods and geodesic distance functions

    Författare :Ola Nilsson; Ken Museth; Hamish Alan Carr; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The work in this thesis focuses on efficient implementations of level-set methods and geodesic distance functions. The level-set method is a grid based design that inherits many favorable traits from implicit geometry. LÄS MER
