  1. 1. Independent Project in Chemical Engineering and Materials Engineering : A literature study of powder-based additive manufacturing

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Daniel Feldt; Petra Hedberg; Asker Jarlöv; Elsa Persson; Mikael Svensson; Filippa Vennberg; Therese You; [2018]
    Nyckelord :Additive manufacturing; selective laser melting; electron beam melting; binder jetting; stainless steel; tool steel; nickel alloys;

    Sammanfattning : The focus of this literary study was additive manufacturing (AM) and the purpose was to find general trends for selected materials that have been additively manufactured and compare them to results from other reviews. The raw materials studied were stainless steels 316L, 17-4 PH, 15-5 PH and 420, as well as tool steel H13 and nickel alloys 625, 718 and Hastelloy X. LÄS MER

  4. 3. CFD simulations of Luleälven : An examination of CFD as a tool forevaluating restoration possibilities of regulated dredgedrivers

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Mikael Hedberg; [2018]
    Nyckelord :CFD; Riverine Grayling; Restoration; River; Regulated;

    Sammanfattning : Dredged rivers remain from when lumber was floated downriver for processing and shipping purposes. This has left parts of some rivers in Sweden with shallow rocky beaches and deep central furrows. Restoration efforts of dredged unregulated rivers has shown positive results for fish populations.

  5. 4. Säker arbetsmiljö med visuell planering

    Uppsats för yrkesexamina på grundnivå, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Mikael Johansson; John Hedberg; [2017]
    Nyckelord :Lean; visuell planering; 5s; arbetsmiljö; arbetsmiljöverket; säkerhetskultur; SAM;

    Sammanfattning : Arbetsmiljö är något som står högt på agendan i byggbranschen idag. Produktionen ökar dessutom stadigt och sysselsättningen ökar inom branschen. Trots en hög prioritering av arbetsmiljöarbetet sker det för många byggarbetsplatsolyckor idag. LÄS MER

  7. 5. Train Localization and Speed Estimation Using On-Board Inertial and Magnetic Sensors

    Master-uppsats, Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Erik Hedberg; Mikael Hammar; [2015]
    Nyckelord :signal processing; railway tracks; trains; localization; speed estimation;

    Sammanfattning : Positioning systems for trains are traditionally based on track-side infrastructure, implying costs for both installation and maintenance. A reliable on-board system would therefore be attractive. Sufficient reliability for on-board systems is likely going to require a multi-sensor solution. LÄS MER
