1. 6. 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. 7. 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. 8. 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. 9. Towards a Reliable and Valid Analysis of VO2m Off-Kinetics

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Hrafnkell Þráinsson; [2022]
   Keywords : Sports Technology; Near-infrared spectroscopy; Muscle oxidative capacity; Occlusion; Software; Automation; Idrottsteknologi; Near-infrared spectroscopy; Muskulaturens oxidativa förmåga; Ocklusion; Programvara; Automatisering;

   Abstract : Non-invasive methods to evaluate skeletal muscle oxidative capacity have beenemerging as a viable substitute for invasive methods in recent years. One ofthose methods utilises near-infrared spectroscopy (NIRS) to calculate V O2mrecovery off-kinetics following an exercise. READ MORE

6. 10. Structural and Functional Brain Changes due to Pregnancy and Early Postpartum Period: A Systematic Review

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Sanne Lövgren; [2022]
   Keywords : pregnancy; brain; structural; functional;

   Abstract : A big part of the female population experience pregnancy and giving birth. Evidence from animal studies indicates numerous adaptations in the brain throughout pregnancy and the postpartum period. The effects on the human brain are not as well studied, which is problematic due to the complexity of comparing species. READ MORE
