  1. 21. Single Photon LSCM in the NIR Range

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Klara Wallenbro; [2022]
    Nyckelord :LSCM; NIR; SNSPD; LSCM; NIR; SNSPD;

    Sammanfattning : In this thesis a near-infrared laser scanning confocal microscope (NIR-LSCM) is built to operate with optimal performance at 1550nm in combination with simultaneous LED light imaging at 970nm. For detection, a camera equipped with a complementary metal oxide semiconductor (CMOS) sensor and a superconducting nanowire single photon detector (SNSPD) are used for the LED part and the LSCM part, respectively.

  3. 22. Dye sensitzation effects on lanthanide upconversion nanoparticles

    Kandidat-uppsats, KTH/Fysik

    Författare :Dag Albin Bäck; Andreas Jörgensen; [2022]
    Nyckelord :Dye sensitization; lanthanide upconversion nanoparticles; upconversion nanoparticles; UCNP; IR806;

    Sammanfattning : In this report we studied the properties of the dye IR806 and possible mechanisms of the dye sensitization effect on ytterbium-erbium co-doped upconversion nanoparticles. We found that the dye IR806 has two primary emission peaks in the NIR spectral range at around 850 nm and at around 950 nm. LÄS MER

  4. 23. Life cycle analysis and comparison of climate impact for two alternative floor systems for increased weight in high-rise timber buildings

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Nir Kedem; [2022]
    Nyckelord :Life cycle assessment; LCA; Anavitor; Environmental impact; Building materials; Timber; Concrete; Gravel; Adding weight system.;

    Sammanfattning : The aim of this Master Thesis is to investigate and quantify the climate impact for two floor system alternatives for the Cederhusen project, that is the 8 floors timber-based buildings located at Sankt Eriksplan in Stockholm. The overall motivation for this study is the fact that the construction industry is a major contributor to the total amount of the global greenhouse gas emissions. LÄS MER

  5. 24. Contrastive Multimodal Image Representations for Deformable Image Registration

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Love Nordling; [2022]
    Nyckelord :;

    Sammanfattning : Image registration is the process of finding correspondences between images of the same or of similar scenes. Multimodal image registration is the specific case where the images are captured with different imaging systems. LÄS MER

  7. 25. Real-time characterization of fuel by Near-Infrared spectroscopy : Quantitative measurements of moisture content, ash content, heating value, and elemental compositions in solid biofuel mixtures

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Kajsa Edlund; Ali Ahmad Shahnawazi; [2021]
    Nyckelord :NIR; spectroscopy; solid biofuel mixtures; moisture content; ash content; heating value; elemental composition; boiler; CHP pant; CCS; CO2; emissions; NIR; spektroskopi; fasta biobränsleblandningar; fukthalt; ask innehåll; värmevärde; elementär komposition; panna; kraftvärmeverk; CCS; CO2; utsläpp;

    Sammanfattning : The global energy demand supplies mainly from fossil fuels, which is neither sustainable nor environmentally friendly and aims to global warming. Therefore, both more investments in renewable energy sources such as bioenergy are required, as well as new technologies such as carbon capture and storage (CCS) to handle the emissions from existing combined heat and power (CHP) plants.
