  1. 1. A Novel Method for Measuring Low Energy Excitations with BLS

    University essay from Uppsala universitet/Materialfysik

    Author : Christopher Borchert; [2024]
    Keywords : ;

    Abstract : This report presents the work done on an optical setup combining Raman and BLS spectroscopy and discusses the achieved improvements of the system. After some general optimization and minor redesigning, a new alternative beam path was implemented. READ MORE

  3. 2. Circular economy of spare parts and data-driven analytics - “Unlocking Sustainable Value: Analyzing Buyback Policy Circularity Performance in Volvo Group’s Reverse Supply Chain - A Renault Trucks Case Study”

    University essay from Göteborgs universitet/Graduate School

    Author : Vladyslav Zahladko; [2023-07-20]
    Keywords : closed-loop supply chain; reverse logistics; buyback policy; circular economy; performance measurement; supply chain analytics;

    Abstract : To address the current environmental challenges, companies are steadily shifting from a linear to a circular model in their daily operations. This process implies supplementing the traditional forward logistics with a reverse flow, enabling the reuse, remanufacturing, and recycling of existing products. READ MORE

  4. 3. Laser Metrology for assembly of ATLAS ITk-Strips

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Jonathan Arvin; Johannes Berg Wallin; Hugo Eskner; Olof Lindman Jardfelt; [2023]
    Keywords : Laser metrology; ATLAS; Inner Tracker ITk ; Micro Epsilon;

    Abstract : The ATLAS detector at CERN's Large Hadron Collider has been instrumental in scientific discoveries,including the Higgs particle. As part of the High Luminosity (HL) upgrade, the current Inner Detector (ID) isbeing replaced by the new IInner Tracker (ITk), and Uppsala University is collaborating with industrypartner NOTE to produce around 700 modules for the ITk.

  5. 4. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Douglas Björkengren; [2023]
    Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

    Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

  6. 5. Prediction of Reverberation Time in Office Spaces by Investigation of the Scattering Factor in Odeon

    University essay from KTH/Teknisk akustik

    Author : Viktor Söderlund; [2023]
    Keywords : Scattering Factor; Reverberation Time; Odeon; Sabine; Arau-Puchades; Spridningsfaktor; Efterklangstid; Odeon; Sabine; Arau-Puchades;

    Abstract : Accurate estimations of the reverberation time of furnished office spacesis essential as an acoustic consultant. A time efficient way to predict thefurniture’s effect is to investigate it by software modelling. The room acousticsoftware Odeon is suitable for doing this. READ MORE
