  1. 1. Neutron Irradiation Techniques

    Författare :Julius Scherzinger; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actinide Be; fast-neutrons; NE-213 liquid scintillator; He-4 scintillators; pulse-shape discrimination; Cf-252; absolute detection efficiency; neutron irradiation; Fysicumarkivet A:2016:Scherzinger;

    Sammanfattning : The He-3 “crisis” has become a fact in the last decade and large scale neutron detectors based on He-3 technologies have become unaffordable. This new He-3 reality has resulted in a major effort worldwide to develop replacement neutron-detector technologies. LÄS MER

  3. 2. In Vivo Diffuse Reflectance Spectroscopy of Human Tissue : From Point Measurements to Imaging

    Författare :Erik Häggblad; Göran Salerud; Tomas Strömberg; Maurice C. G. Maurice C. G. Aalders; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical engineering; Medicinsk teknik;

    Sammanfattning : This thesis presents the non-invasive use of diffuse reflectance spectroscopy (DRS) to provide information about the biochemical composition of living tissue. During DRS measurements, the incident, visible light is partially absorbed by chromophores but also scattered in the tissue before being remitted. LÄS MER

  4. 3. Energy Efficiency in Residential Buildings in Mozambique - Measurements and Simulations

    Författare :Gabriel Auziane; Byggproduktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy; Building; Measurements; Simulations; DEROB-LTH; Mozambique; Subtropical and Tropical climates; Energy efficiency; PV system; Electrical energy savings.;

    Sammanfattning : Mozambique, situated in south-east Africa, has sub-tropical and tropical climate and plenty of natural resources for energy production. The country is however poor, and only about 25% of the population has access to electricity from the grid. LÄS MER

  5. 4. Measurements, Analysis Techniques and Experiments in Sound and Vibration : Applied to Operational MRI Scanners and in Remote Laboratories

    Författare :Imran Khan; Lars Håkansson; Ingvar Claesson; Josef Ström Bartunek; Gustavo R. Alves; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Noise Control; Remote Laboratories; Sound and Vibration Measurements; Vibration Analysis; Vibration Transmission;

    Sammanfattning : High quality noise and vibration measurements outside of a laboratory environment on real life structures and applications are not trivial. True boundary and operating conditions enforce unique challenges on the measurements. Measurements in hazardous situations such as high magnetic fields, and high temperature environments, etc. LÄS MER

  7. 5. Design of Functional Structures and Measurement Techniques for Electromagnetic Waves

    Författare :Johan Lundgren; Teoretisk elektroteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional structures; frequency selective structures; polarization selectivity; metasurface; near-field measurements; antenna measurements; scattering measurement; power density; random media;

    Sammanfattning : Electromagnetic fields exist all around us. Through evolution, nature has developed tools to interact and use these fields, where our eyes are a spectacular example. Humans have a long history of developing structures and objects of their own to alter and interact with these fields. LÄS MER
