  1. 41. Continuous-Time Models in Kernel Smoothing

    Författare :Martin Sköld; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; deconvolution; errors-in-variables; continuous time; dependent data; bandwidth selection; asymptotic variance; Density estimation; kernel smoothing; size bias.; Mathematics; Matematik;

    Sammanfattning : This thesis consists of five papers (Papers A-E) treating problems in non-parametric statistics, especially methods of kernel smoothing applied to density estimation for stochastic processes (Papers A-D) and regression analysis (Paper E). A recurrent theme is to, instead of treating highly positively correlated data as ``asymptotically independent'', take advantage of local dependence structures by using continuous-time models.

  3. 42. Atom-Diatom Scattering. From Potential Energy Surfaces to Rate Constants

    Författare :Erik Abrahamsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is about the theoretical study of collisions between atoms and diatomic molecules. It might seem like a trivial problem, but in reality it is a highly complex process. Despite, or because of, their apparent simplicity, these processes are of importance for a broad area of science.

  4. 43. Flow and Compression of Granulated Powders : The Accuracy of Discrete Element Simulations and Assessment of Tablet Microstructure

    Författare :Ann-Sofie Persson; Göran Frenning; Göran Alderborn; Marie Wahlgren; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Discrete Element Method; Granule; Flow; Angle of Repose; Discharge Rate; Shear; Rolling friction; Compression; Elastic deformation; Microstructure; Degree of compression; Tensile strength; Galenisk farmaci; Pharmaceutics;

    Sammanfattning : Simulations are powerful and important tools for gaining insight into powder processes. Ultimately, simulations have the potential to replace experiments. Thus, accurate models and insight into the essential factors for descriptions of powder behaviour are required. LÄS MER

  5. 44. Nucleotide-Dependent Processes in the Thylakoid Lumen of Plant Chloroplasts

    Författare :Björn Lundin; Cornelia Spetea Wiklund; Zach Adam; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plant; chloroplast; thylakoid; nucleotide; PSII; PsbO; Biology; Biologi;

    Sammanfattning : Plants, algae and photosynthetic bacteria are able to harvest the sunlight and use its energy to transform water and carbon dioxide to carbohydrate molecules and oxygen, both important to sustain life on Earth. This process is called photosynthesis and is the route by which almost all energy enters the biosphere. LÄS MER

  7. 45. Hydrogeological Methods in Geotechnical Engineering: Applied to settlements caused by underground construction

    Författare :Jenny Persson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; excavation; tunnel; hydrogeology; consolidation; pumping test; Groundwater; inflow rate; settlement; transmissivity; pore pressure; clay;

    Sammanfattning : Improvement in the infrastructure in urban areas generally involves underground construction with tunneling and deep excavations. One important consideration when constructing in cities founded on soft soil is settlement resulting from groundwater drawdown. The potential cost of excessive settlement in these projects is immense. LÄS MER
