  2. 1. Aspects of lung mechanics during mechanical ventilation

    Author : Magni Gudmundsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute respiratory failure; Acute respiratory distress syndrome; Mechanical ventilation; Transpulmonary pressure; Expiratory time constant; Esophageal pressure;

    Abstract : Background: One of the most common diagnoses in the intensive care unit is acute respiratory failure. In its most severe form it is called acute respiratory distress syndrome and often requires mechanical ventilation. READ MORE

  4. 2. Fabrication, characterization, and modeling of metallic source/drain MOSFETs

    Author : Valur Gudmundsson; Per-Erik Hellström; Yee-Chia Yeo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallic source drain; contact resistivity; Monte Carlo; NiSi; PtSi; SOI; UTB; tri-gate; FinFET; multiple-gate; nanowire; MOSFET; CMOS; Schottky barrier; silicide; SALICIDE;

    Abstract : As scaling of CMOS technology continues, the control of parasitic source/drain (S/D) resistance (RSD) is becoming increasingly challenging. In order to control RSD, metallic source/drain MOSFETs have attracted significant attention, due to their low resistivity, abrupt junction and low temperature processing (≤700 °C). READ MORE

  5. 3. Defence capabilities of human intestinal epithelial cells

    Author : Anna Fahlgren; Sten Hammarström; Marie-Louise Hammarström; Gudmundur Gudmundsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; intestine; mucosa; epithelium; antimicrobial; defensins; glycocalyx; ulcerative colitis; Crohn´s disease; celiac disease; Immunologi; Immunology; Immunologi; immunologi; Immunology;

    Abstract : The epithelial cells lining the intestinal mucosa separate the underlying tissue from components of the intestinal lumen. Innate immunity mediated by intestinal epithelial cells (IECs) provides rapid protective functions against microorganisms. Innate immunity also participates in orchestrating adaptive immunity.

  6. 4. Toward fully automatic earthquake detection and processing for tomography in the Hengill area

    Author : Frederic Wagner; Ari Tryggvason; Ólafur Gudmundsson; Roland Roberts; Steven Gibbons; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earthquake detection; local-earthquake tomography; Iceland; induced seismicity; geothermal activity; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Abstract : This thesis focuses on the automation of seismic data analysis, in particular, event detection, quality assessment of detected events, and preparation of an earthquake catalogue for seismic tomography.The developed event detector uses back-propagation and stacking of a seismic trace attribute with a known velocity model to detect and locate events.

  7. 5. Seismicity and crustal structure in Iceland

    Author : Claudia Abril; Ólafur Gudmundsson; Vala Hjörleifsdóttir; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earthquake relocation; local earthquake tomography;

    Abstract : The main goal of this Ph.D. thesis is to improve locations of earthquake hypocenters and to resolve heterogeneous crustal structure and its effects on travel times. The data and case studies are drawn from the Icelandic national SIL network and the temporary NICE project deploy-ment in the Tjörnes Fracture Zone. READ MORE
