  1. 6. Evaluation and optimization of cation exchanging materials for life-span optimization of engine oil

    Master-uppsats, Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Författare :Mima Ceco; [2013]
    Nyckelord :cation exchanger; buffering additive; engine oil; total base number; pIH method; inductively coupled plasma atomic emission spectroscopy;

    Sammanfattning : Requirements of high performing engine oil are today necessary since the development of new machinery with modern standardsis a cutting edge technology demanding highly optimized components. One way of increasing the lubricating properties of engineoil is through the addition of antioxidants. LÄS MER

  3. 7. Flödesoptimering i begränsande resurs

    Kandidat-uppsats, JTH, Industriell organisation och produktion

    Författare :Jesper Bergström; Rickard Karlsson; [2012]
    Nyckelord :Logistics; SMED-analysis; Bottleneck; Capacity; Utilization rate; Setup time; Setup time reduction; Process mapping; Process analysis; Logistik; SMED-analys; Flaskhals; Kapacitet; Utnyttjandegrad; Ställtid; Ställtidsre-duktion; Processkartläggning; Processanalys;

    Sammanfattning : Most companies have a bottleneck in their production, that is a constraining re-source. When the demand is higher than the capacity in the constraining resource it is impossible to produce the demanded output. This problem leads to delayed deliveries, unhappy customers and ultimately to decreased revenue. LÄS MER

  4. 8. Identification of paper and influence of its homogeneity in forensic investigations by ICP-AES/MS and other non-invasive spectroscopic techniques

    Master-uppsats, Medicinska fakulteten

    Författare :Doreen-Marie Shamon; [2012]
    Nyckelord :;

    Sammanfattning : The purpose with this thesis was to find out if ordinary office paper was homogenous throughout the sheet in context of organic and elemental content. Two different types of papers were also analyzed, paper towel and corrugated paperboard. LÄS MER

  5. 9. Vattenskärning : Teknologin och dess tillämpningsområden

    Kandidat-uppsats, KTH/Industriell produktion

    Författare :Sami A Österman; Shirish Kumar; [2010]
    Nyckelord :;

    Sammanfattning : Vattenskärning anses generellt vara en mångsidig bearbetningsteknik med en mängd tillämpningsområden. Ren vattenskärning gör det möjligt att skära i mjuka material som gummi, medan tillsatt abrasivmedel tillåter skärning av bland annat stål och keramik. Skärningen lämnar inga restspänningar eller någon värmepåverkan i materialet. LÄS MER

  7. 10. Utveckling av rotationshuvud till CNC-testbänk

    M1-uppsats, Fakulteten för teknik- och naturvetenskap

    Författare :Alexander Hjelm; [2010]
    Nyckelord :;

    Sammanfattning : The thesis was written during an internship at ProCom GmbH in Aachen, Germany. It is a project with the goal to upgrade their already existing three linear axis test bench with two additional rotary axes. The task is to either find an already existing solution or to design, manufacture and install a rotary head on the test bench. LÄS MER
