  1. 16. Simulation of Quantum Cascade Lasers

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Author : Zakaria Mohamed; [2023]
    Keywords : Quantum Cascade Lasers; Simulations; Numerical Methods; Computational Models; Heterostructures; Physics and Astronomy;

    Abstract : This thesis aimed to contribute to the improvement of Quantum Cascade Lasers (QCLs) by focusing on the effective determination of quantum levels in these devices. The current method relies on an outdated Fortran code, which poses challenges when integrating into optimization schemes. READ MORE

  3. 17. 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. 18. Electrolyte filling process parameter study for a hard case prismatic lithium-ion battery : Understand the influence of vacuum pressure curve on the filling cycle to device a method to optimise the cycle time.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Rajath Alva Kotekunja; [2023]
    Keywords : Lithium ion batteries; electrolyte filling; cycle time; non destructive method;

    Abstract : Lithium ion Batteries (LIB) as electrochemical energy storage systems are key alternatives to fossil fuels and enable the storage of energy from alternate renewable resources due to low weight, High energy density and long lifetime. Batteries have become a dominant consumer electronics in the past two decades[1]. READ MORE

  5. 19. Quality Control in Aluminium Profiles : Non-destructive Methods using Non-linear Ultrasonic

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Viktor Svensson; Robin Raymundsson; [2023]
    Keywords : Acoustic; defect; detection; harmonic; Akustisk; defekt; detektion; överton;

    Abstract : When aluminium profiles are manufactured, defects may arise, especially when theprofiles are manufactured through extrusion. During the extrusion process, thesedefects occur on parts of the extruded material because of contaminates that needto be found. READ MORE

  6. 20. Simulations and modeling of light propagation in biological tissue

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

    Author : Emma Hjörneby; [2023]
    Keywords : Technology and Engineering;

    Abstract : The GASMAS technique has previously proven useful for examining and measuring the oxygen concentration in the lungs of preterm infants. GASMAS can distinguish absorption by one gas from the bulk absorption of the surrounding media, and can provide an instant, non-invasive and non-destructive way of examining lungs, and diagnosing dangerous conditions such as pneumothorax.
