1. 36. 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

3. 37. 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.

4. 38. Image Fusion of Infrared and Visible Images for Computer Vision Tasks

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Emil Friðriksson; [2023]
   Keywords : ;

   Abstract : Reliable perception in all type of weather conditions is an integral part of autonomous vehicles. In recent years, infrared cameras have become more accessible resulting in increased research and a handful of publicly available datasets that provide image pairs of infrared and visible images.

5. 39. Urban tree canopy mapping -an open source deep learning approach

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Tobias Rydlinge; [2023]
   Keywords : Geography; GIS; AI; deep learning; urban trees; remote sensing; Earth and Environmental Sciences;

   Abstract : Urban trees have an important role to provide ecosystem services and to make our cities greener and more sustainable. The changing climate and densification of cities make it even more valuable to preserve and investigate in urban trees. READ MORE

6. 40. Focal Spot Optimization Using Spatial Light Modulation and a Phase Retrieval Algorithm

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Robert Petersen; [2023]
   Keywords : Spatial Light Modulation; Phase Retrieval Algorithm; Focal Spot Optimization; Adaptive Optics; Wavefront Sensing; Lasers; Physics and Astronomy; Technology and Engineering;

   Abstract : Aberrations to the wavefront of a laser beam reduce the quality of the focal spot and are generally undesired. This project is aimed at determining the aberrations of laser beams by using a phase retrieval algorithm and to show that it is possible to correct the aberrations with a spatial light modulator to optimize the focal spot.
