  1. 1. RF Compressor (SLED) Phase-Modulation to Reduce Peak Fields in the MAX IV Linear Accelerator

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Joel Ekström; [2023]
    Nyckelord :Accelerator; MAX IV; LINAC; Phase-modulation; SLED; Pulse compression; Technology and Engineering;

    Sammanfattning : Modern particle accelerators need strong electric fields in order to produce high energy particles. Such high voltages are typically reached by injecting pulsed radio frequency power through several steps of amplification. At the end, pulse compression is used to further improve the energy gain at the cost of pulse-length. LÄS MER

  3. 2. Cutting emissions with remanufacturing

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Maja Anehagen; [2021]
    Nyckelord :Life cycle assessment; LCA; Remanufacturing; Resource efficiency; Circular economy; Electric and electronic equipment; Hardware manufacturing sector; Earth and Environmental Sciences;

    Sammanfattning : An increase in the use of natural resources is directly associated with an increased environmental impact. It is therefore of importance to lead the manufacturing industry towards a route of material efficiency. Remanufacturing is an industrial process that brings a used product and its components back to like-new or better condition. LÄS MER

  4. 3. Airing Out the Dirty Laundry

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Thomas Hallman; [2019]
    Nyckelord :Demand Side Management; electricity consumption peaks; residential electricity use; grid capacity; Earth and Environmental Sciences;

    Sammanfattning : A variety of demand side management (DSM) methods are needed to ensure electric grid reliability and to integrate increasing shares of renewable energy sources into electricity networks. To investigate whether communal laundry rooms in Stockholm represent a good candidate for employing DSM to reduce the severity of electricity load peaks, tenants are surveyed on their willingness to temporarily lose some laundry schedule availability during typical peak load hours.

  5. 4. Ökad plaståtervinning vs giftfria materialflöden - En analys av ändringen av POPs-förordningen

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Emilia Sevelius; [2019]
    Nyckelord :Circular economy; recycling; chemicals; WEEE; environmental-political goals; POPs recast; contradictions; Earth and Environmental Sciences;

    Sammanfattning : To realize the transition from a linear to a circular economy within the EU, the union has developed environmental-political goals and implemented them through policies that take a product’s whole life cycle into account. Two important objectives that are expressed through these policies are increased recycling and the phasing out of hazardous chemicals such as persistent organic pollutants which have negative effects on human health and sensitive ecosystems.

  7. 5. Skjuvhållfasthetsbestämning i kohesionsjord : en del av ett utvecklingsprojekt för en ny vingförsöksutrustning

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Frida Lundin; [2018]
    Nyckelord :Skjuvspänning; Lera; Vingförsök; Parameterstudie; Nova-log vane;

    Sammanfattning : The report is part of the development project run by Ingenjörsfirman Geotech AB, where some of the field investigations were carried out in collaboration with Bohusgeo AB. The aim of the thesis is to do field investigations with the new Vane Geotech Nova (Nova-vane) equipment, and compare the results with known and proven methods. LÄS MER
