1. 11. Development and Optimization of Near-infrared spectroscopy

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Amanda Hahlin; [2023]
   Keywords : Near-infrared spectroscopy; NIRS; Textile sorting; Principal component analysis; PCA; Post-consumer end-of-life textiles;

   Abstract : With the growing demand for sustainable options, the existing sorting capacities are limiting the potential for fiber-to-fiber recycling. With the help of near-infrared spectroscopy (NIRS), automated sorting of textiles with high accuracy is possible due to the easy access for polymer identification. READ MORE

3. 12. Prediction of Plastic Fragments in Recycled Paper Using Near-Infrared Spectroscopy

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Fidan Alieva; [2023]
   Keywords : Near-infrared spectroscopy; paper packaging; barrier materials; recycling; multivariate data analysis; Nära-infraröd spektroskopi; pappersförpackningar; barriärmaterial; återvinning; multivariat dataanalys;

   Abstract : Sustainability has gained a lot of attention in the field of research. Researchers and consumers both prioritize sustainability and environmental issues over previously dominant materials, such as plastic. Packaging and disposable items that used to be made of plastic have largely been replaced with paper. READ MORE

4. 13. The use of hyperspectral sensors for quality assessment : A quantitative study of moisture content in indoor vertical farming

   University essay from Mälardalens universitet/Akademin för innovation, design och teknik

   Author : Arezo Ahaddi; Zeineb Al-Husseini; [2023]
   Keywords : Hyperspectral Imaging; lettuce; moisture content; NIR; near-infrared spectroscopy; shelf life; quality assessment; vertical farming; MicroNIR;

   Abstract : Purpose: This research will study how hyperspectral sensoring can assess the moisture content of lettuce by monitoring its growth in indoor vertical farming. Research questions: “What accuracy can be achieved when using hyperspectral sensoring for assessing the moisture content of lettuce leaves grown in vertical farming?” “How can vertical farming contribute to sustainability in conjunction with integration of NIR spectroscopy?” Methodology: This study is an experimental study with a deductive approach in which experiments have been performed using the hyperspectral technologies singlespot sensor and the hyperspectral camera Specim FX17 to collect spectral data.

5. 14. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

   University essay from KTH/Tillämpad fysik

   Author : Alexandros Bampis; [2023]
   Keywords : Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

   Abstract : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. READ MORE

6. 15. 3D Gaze Estimation on Near Infrared Images Using Vision Transformers

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Emil Emir Vardar; [2023]
   Keywords : Gaze estimation; Eye tracking; Vision Transformers ViTs ; Hybrid ViTs; Deep learning; Near-infrared NIR images; Ögonblicksuppskattning; Blickspårning; Vision Transformers ViTs ; Hybrida ViTs; Djupinlärning; Nära-infraröda NIR bilder;

   Abstract : Gaze estimation is the process of determining where a person is looking, which has recently become a popular research area due to its broad range of applications. For example, tools that estimate gaze are used for research, medical diagnosis, virtual and augmented reality, driver assistance system, and many more. READ MORE
