  1. 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 Nanoscience

    Author : Qianhui Liu; [2022]
    Keywords : Ambient pressure x-ray photoelectron spectroscopy; Event-averaging; Pd 100 surface structure oscillation; Physics and Astronomy;

    Abstract : 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.

  3. 12. QC upgrade and verification for HS-Lenti RT Activity Kit

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Annie Eriksson; Elisabeth Lööf; Filippa Nilsson; Niklas Eckert Elfving; Sadat Chowdhury; Simon Oscarson; Tove Jonsson; [2022]
    Keywords : ;

    Abstract : The aim of this project was to present a cost-efficient quality control routine to ensure thefunctionality of HS-Lenti RT Activity Kit, an ELISA-based kit produced by Cavidi AB, thatscreens for lentiviruses such as HIV. Two main methods for quality control are presented inthis report; acceptance sampling and Statistical Process Control (SPC). READ MORE

  4. 13. OSL dating of the Mesolithic site Nilsvikdalen 7, Bjorøy, Norway.

    University essay from Lunds universitet/Geologiska institutionen

    Author : Elin Jirdén; [2022]
    Keywords : OSL dating; luminescence; SAR protocol; water content; archaeology; Late Mesolithic; Norway.; Earth and Environmental Sciences;

    Abstract : 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

  5. 14. Predictive Maintenance of Servo Guns

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Joakim Ifver; [2022]
    Keywords : ;

    Abstract : 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

  6. 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 systemteknik

    Author : Sabina Westergren Ahlin; Agnes Höglund; [2022]
    Keywords : paperboard; variability; FFT; Fast Fourier Transform; Fourier transform; app; application; GUI; Graphical User Interface;

    Abstract : 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
