  1. 1. Robust Water Balance Modeling with Uncertain Discharge and Precipitation Data : Computational Geometry as a New Tool

    Författare :José-Luis Guerrero; Sven Halldin; Stefan Uhlenbrook; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alpha shape; Convex hull; Depth function; Discharge; Hydrological models; Honduras; Model calibration; Parameter-value estimation; Precipitation; Rating curve; Robust; Robustness; Uncertainty estimation; Water resources.; Alfaform; avbördningskurva; djupfunktion; Honduras; hydrologiska modeller; konvext hölje; modellkalibrering; nederbörd; osäkerhetsskattning; parametervärdesskattning; robust; robusthet; vattenföring; vattenresurser; Hydrology; Hydrologi;

    Sammanfattning : Models are important tools for understanding the hydrological processes that govern water transport in the landscape and for prediction at times and places where no observations are available. The degree of trust placed on models, however, should not exceed the quality of the data they are fed with. LÄS MER

  3. 2. Driving rain tightness, intrusion rates and phenomenology of leakages in defects of façades: A new calculation algorithm

    Författare :Lars Olsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; façade details; rain resistance; window-wall interface; EN 12865; protrusion; deficiency; catch area; water flow; obstacle; fenestration; dam; driving rain; water leakage; leakage flow; hole;

    Sammanfattning : This thesis presents the driving rain tightness of façades with façade details as well as the water leakage flows that can be expected. Furthermore, it describes the key mechanisms for water leakage in defects in the outermost layer of external walls. LÄS MER

  4. 3. Multilayer X-ray mirrors for water window wavelengths

    Författare :Fredrik Eriksson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis describes the design, growth and x-ray characterization of normal incidence multilayer x-ray mirrors. The mirrors are intended as condenser optics for soft x-ray microcsopy in the water window.A droplet-target laser-plasma soft x-ray source has been developed to be used in a compact soft x-ray microscope.

  5. 4. Electron-Impact Liquid-Jet Water-Window X-ray Sources

    Författare :Peter Anders Skoglund Lindberg; Hans M. Hertz; Oscar Tjernberg; KTH; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This Thesis describes the development and characterization of a soft x-ray liquidjet-anode electron-impact source. With a water-jet target the primary emission is the O Kα line at 525 eV. This is close to the lower edge of the water-window, a spectral region lacking simple laboratory sources. LÄS MER

  7. 5. System analysis of a PV/T hybrid solar window

    Författare :Henrik Davidsson; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar window; PV T hybrid; building integration; TRNSYS;

    Sammanfattning : A building-integrated multifunctional PV/T solar window was suggested and developed by Andreas Fieber. The solar window is constructed of PV cells laminated on solar absorbers placed in a window behind the glazing. LÄS MER
