1. 1. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Kaibin Wen; [2023]
   Nyckelord :Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography; Additiv tillverkning; värmeöverföring; infraröd termografi; ytjämnhet; finita elementmetoden;

   Sammanfattning : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. LÄS MER

3. 2. EMC-Optimized Transparency: Reducing Electromagnetic Emissions in Surveillance Camera Domes

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Fabian Sondh; Erik Hansson; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : Electromagnetic compatibility (EMC) is a crucial aspect to product development. Companies need to make sure their products live up to the standards that exists around the world. One way of reducing electromagnetic emissions is to shield the product, using some conducting material, for instance, copper. LÄS MER

5. 4. 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.

7. 5. Focal Spot Optimization Using Spatial Light Modulation and a Phase Retrieval Algorithm

   Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

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

   Sammanfattning : 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.
