  1. 1. Non-Invasive Monitoring of Architectural Heritage

    Författare :Jenny Hällström; Bebyggelsevård; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; remote sensing; lidar; laser-induced fluorescence; documentation; hyperspectral; non invasive; non destructive; sustainable maintenance; conservation planning; monitoring; Coliseum; architectural conservation; restoration; Övedskloster; deterioration; Lateran Baptistery; stone; brick; thematic mapping; in situ; imaging; biodeteriogens;

    Sammanfattning : The on-site documentation and examination of architectural heritage has presented challenges for traditional analysis methods in the form of, among other things, large complex structures, sites and environmental conditions. In recent years there has been growing interest in assessing progressing deterioration processes and material analysis, with an emphasis on sustainable conservation and maintenance planning. LÄS MER

  3. 2. Structural health monitoring using modern sensor technology : long-term monitoring of the New Årsta Railway Bridge

    Författare :Merit Enckell; Håkan Sundqvist; Daniele Inaudi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Health Monitoring; bridges; sensory technology; fibre optics; concrete.; Building engineering; Byggnadsteknik;

    Sammanfattning : Structural Health Monitoring (SHM) is a helpful tool for engineers in order to control and verify the structural behaviour. SHM also guides the engineers and owners of structures in decision making concerning the maintenance, economy and safety of structures. LÄS MER

  4. 3. Treeline dynamics in short and long term perspectives : observational and historical evidence from the southern Swedish Scandes

    Författare :Lisa Öberg; Bengt-Gunnar Jonsson; Leif Kullman; Ulf Segerström; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Betula pubescens ssp. czerepanovii; Picea abies; Pinus sylvestris; climate change; monitoring; treeline advance; clones; megafossils; immigration; Holocene; cryptic refugia; Swedish Scandes; Terrestrial ecology; Terrestrisk ekologi;

    Sammanfattning : Against the background of past, recent and future climate change, the present thesis addresses elevational shifts of alpine treelines in the Swedish Scandes. By definition, treeline refers to the elevation (m a.s.l. LÄS MER

  5. 4. Quality Assessment and Monitoring of Maternal Referrals in Rural Tanzania

    Författare :Andrea Barnabas Pembe; Elisabeth Darj; Pia Olsson; Lennarth Nyström; Anders Carlstedt; Albrecht Jahn; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Quality; maternal referral; counselling; monitoring; rural; Tanzania; Reproductive health; Reproduktiv hälsa; International Health; Internationell hälsa;

    Sammanfattning : An efficient referral system is essential in providing access to emergency obstetric care at higher levels of care by supporting antenatal and delivery services in the primary level of care facilities (PLCF). The aim of this thesis was to assess community and health service factors affecting the quality of maternal referrals in rural Tanzania. LÄS MER

  7. 5. Lessons Learned in Structural Health Monitoring of Bridges Using Advanced Sensor Technology

    Författare :Merit Enckell; Johan Silfwerbrand; Konrad Bergmeister; KTH; []
