1. 26. Detection of nitrous oxide through IR-DFWM in gas flows with future application in ammonia flames

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

   Author : Martin Passad; [2021]
   Keywords : Physics; Optics; Lasers; Environment; Hydrogen; Hydrogen Energy; Ammonia Energy; DFWM; Ammonia; Nitrous Oxide; Ammonia Flame; Ammonia Combustion; Physics and Astronomy;

   Abstract : This thesis report on an investigation into the applicability of mid-infrared degenerate four-wave mixing (IR-DWFM) as a method to detect N\(_2\)O in ammonia flames. DFWM has previously been used for concentration measurements on other molecules, but has never, to the author's knowledge, been applied to measure N\(_2\)O in ammonia flames before. READ MORE

3. 27. Strengthening Efficiency and Safety in Forklift Operations through Autobiographical Design

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

   Author : Nino Khodr; [2021]
   Keywords : Forklifts; Warehouse; Efficiency; E-Commerce; Internet of things.;

   Abstract : Forklift vehicles used for moving pallets and boxes in warehouses, have recently been integrated with Internet of Things (IoT) technology, in effect making forklifts networked and in parts controllable from afar. Human operators now carry out tasks according to instructions displayed on the screen of the IoT-forklift instead of just maneuvering around and executing tasks as they see fit. READ MORE

4. 28. Test setup for LDMX HCal readout

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Joshua Greaves; [2020]
   Keywords : Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

   Abstract : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.

5. 29. Study of reflective and polarization properties of objects found in automotive LiDAR applications

   University essay from Umeå universitet/Institutionen för fysik

   Author : Daniel Tonvall; [2020]
   Keywords : Bidirectional Reflectance Distribution Function; BRDF; Polarization; LiDAR;

   Abstract : In the development of autonomous vehicles, replacing the driver and its perceptive abilities is one of many technical challenges. As a part in solving these challenges, Light Detection And Ranging (LiDAR) is a promising technology. READ MORE

6. 30. Development of Next-Generation Optical Tweezers : The New Swiss Army Knife of Biophysical and Biomechanical Research

   University essay from Umeå universitet/Institutionen för fysik

   Author : Daniel Nilsson; [2020]
   Keywords : optical tweezers; optical fiber tweezers; optical fiber; optical trapping; manipulation; optical force; cell trapping; biophysical; physicochemical; biomechanical; research; next-generation; raman spectroscopy; holographic optical tweezers;

   Abstract : In a time when microorganisms are controlling the world, research in biology is more relevant than ever and this requires some powerful instruments. Optical tweezers use a focused laser beam to manipulate and probe objects on the nano- and microscale. READ MORE
