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

   Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

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

   Sammanfattning : 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.

3. 2. Identification of Environmental Plastic Samples from a Caribbean Beach Survey by Near-Infrared Spectroscopy with the MicroNIR and Chemometric Analysis

   Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

   Författare :David Vigren; [2015]
   Nyckelord :MicroNIR; Near-infrared spectroscopy; Chemometrics; Plastic polymer identification; Environmental plastic beach survey;

   Sammanfattning : MicroNIR is a portable near-infrared diffuse reflection spectroscope. Its suitability for identifying environmental plastic polymers was evaluated through a series of performance tests. The plastic samples were collected during a beach survey in the Caribbean. First a reference database was built by analysing a series of reference plastic polymers. LÄS MER
