11. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for NanoscienceAbstract : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.

13. OSL dating of the Mesolithic site Nilsvikdalen 7, Bjorøy, Norway.
University essay from Lunds universitet/Geologiska institutionenAbstract : Luminescence dating is a well-established dating method within geological and archaeological research. However, the use of luminescence dating, and more specifically optically stimulated luminescence (OSL), is currently underutilised in Norwegian archaeology. READ MORE

14. Predictive Maintenance of Servo Guns
University essay from Högskolan i Halmstad/Akademin för informationsteknologiAbstract : This bachelor thesis investigates the possibility of implementing a system to detect defects with extractable data from ABB’s servo guns. By looking at the deflection data i.e., the electrode position at every stroke, multiple methods are applied to investigate the behavior of the data. READ MORE

15. A Graphical User Interface for IR-image-based Process Analysis : A tool for assessing root causes in paperboard variability
University essay from Uppsala universitet/Avdelningen för systemteknikAbstract : Paperboard is produced in a large and complex process where many parameters can affect its quality. The common methods of analysing paperboard quality are through traversing point-like sensors that only measure a very small fraction of the produced paperboard. READ MORE
