1. 1. 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 The current method relies on an outdated Fortran code, which poses challenges when integrating into optimization schemes.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. 2. Evaluation of MPC and PI control on a Tribometer : Design and comparison of control methods for a Pin-on-Disc Tribometer

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

   Author : Ehab Ziad Raheem; Tore Malmström; [2023]
   Keywords : Control Theory; MPC; PI; PI-Cascade; Tribometer; Pin-on-Disc; Reglersystem; MPC; PI; PI-Kaskadreglering; Tribometer; Stift-På-Skiva;

   Abstract : This thesis compares Model Predictive Control (MPC) and Proportional-Integral (PI) control in a pin-on-disc tribometer. The tribometer consists of a geared Direct Current (DC) motor driving a flywheel and a voice coil actuating a pin onto the surface of the flywheel. READ MORE

4. 3. The effect of lactose fines, magnesium stearate, choice of mixer and mixing process on the performance of adhesive mixtures for inhalation

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Gabriela Ponce Aparicio; [2023]
   Keywords : High shear mixing; low shear mixing; lactose fines; coating agent; budesonide; mixing energy; dry powder inhaler; carrier-based formulations; mixing time; adhesive mixtures; pharmaceutical technology; Technology and Engineering;

   Abstract : Dry powder inhaler (DPI) formulation is a major area of interest since they are employed by the healthcare system to treat relevant chronic diseases like asthma. Previous research has established that the manufacturing process and formulation composition are key for the active pharmaceutical ingredient to reach the lungs and achieve therapeutic effects.

5. 4. Werewolves to Are-wolves? Characterising key factors affecting public acceptance of a hypothetical Experimental Wolf Reintroduction in Scotland

   University essay from Lunds universitet/Internationella miljöinstitutet

   Author : Marta Lamorgese; [2023]
   Keywords : Ecosystem Restoration; Rewilding; Large Predator Reintroduction; Wolf Reintroduction; Public Participation; Social Acceptance; Ex-ante Policy Evaluation; Local Stakeholders Engagement; Integrated Landscape Management; Attitude Formation; Social Sciences;

   Abstract : The newest Scottish government Biodiversity Strategy prioritises control of overabundant deer populations. Ecological theory and real-life instances suggest an unorthodox deer management solution: wolf reintroduction (WR). Theoretically, wolves would prey on deer, thus alleviate grazing pressure on Scottish vegetation and help landscapes thrive. READ MORE

6. 5. Control of an Over-Actuated Vehicle for Autonomous Driving and Energy Optimization : Development of a cascade controller to solve the control allocation problem in real-time on an autonomous driving vehicle

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Gianmarco Grandi; [2023]
   Keywords : LTV-MPC Linear Time-Varying Model Predictive Controller ; Trajectory following; Energy consumption; Vehicle stability; Vehicle model; Real-time performance; LTV-MPC Controllo a predizione del modello lineare tempo variabile ; Inseguimento di traiettoria; Consumo energetico; Stabilità del veicolo; Modello del veicolo; Prestazioni in tempo reale; LTV-MPC Linjär tidsvariabel modellförutsägande styrning ; spårföljning; energiförbrukning; fordonsstabilitet; fordonsmodell; prestanda i realtid;

   Abstract : An Over-Actuated (OA) vehicle is a system that presents more control variables than degrees of freedom. Therefore, more than one configuration of the control input can drive the system to a desired state in the state space, and this redundancy can be exploited to fulfill other tasks or solve further problems.
