  1. 1. Design and construction of a contactless excitation and response measurement system

    Master-uppsats, KTH/Industriell produktion

    Författare :Johan Westlund; [2019]
    Nyckelord :Rotor dynamic; Electromagnet; Contactless excitation; LabVIEW; Measurement instruments; Force control; CERS; Rotordynamik; Elektromagnet; Kontaktlös exitation; LabVIEW; Kraftkontroll; CERS;

    Sammanfattning : Manufacturing industry works on Overall Equipment Effectiveness (OEE) to increase the yield and speed of machining. A good knowledge of the machine properties is important to increase the speed while still maintaining stable cutting with low tool usage. LÄS MER

  3. 2. Den svenska officersutbildningen : Gör vi saker rätt eller gör vi rätt saker?

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap; Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Mathias Holmdahl; Daniel Landin; [2019]
    Nyckelord :Perception; Adaptation; Change; Relevance; Uppfattning; Anpassning; Förändring; Relevans;

    Sammanfattning : Att självkritiskt ställa frågan: ”Gör vi saker rätt eller gör vi rätt saker?” är vitalt om man avser förbättra det man gör. Svensk officersutbildning har bedrivits på Militärhögskolan Karlberg sedan 1792 och dess historia har satt sina spår i dagens officersutbildningssystem. LÄS MER

  4. 3. Skin barrier: Extraction and characterization of Stratum Corneum lipids

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Nicolas Velásquez González; [2018]
    Nyckelord :stratum corneum; skin barrier; lipids; physical chemistry; fysikalisk kemi; Chemistry;

    Sammanfattning : The structure and dynamics of isolated Stratum Corneum lipids in different temperatures and hydration conditions was investigated using natural abundance 13 C NMR and X-ray scattering. In order to isolate the lipids a new extraction method was tested. The novel aspect of this method was its ability to extract more lipids from SC. LÄS MER

  5. 4. Study of vibration severity assessment for Machine Tool spindles within Condition Monitoring

    Master-uppsats, KTH/Industriell produktion

    Författare :Eduardo Torres Pérez; [2016]
    Nyckelord :;

    Sammanfattning : Today, machine tools are indispensable for production of manufactured goods. Several industries rely in this equipment to manufacture finished products by removing material through different cutting operations. Automobile, military and aerospace are just examples of industries where machine tools are used intensively. LÄS MER

  7. 5. Evaluation of a Contactless Excitation and Response System (CERS) for process planning applications : An experimental study

    Master-uppsats, KTH/Industriell produktion

    Författare :Laura Montalban; [2016]
    Nyckelord :mechanical vibrations; natural frequencies; damping ratio; chatter; structural dynamic tests; stability lobe diagrams.; mekaniska vibrationer; egenfrekvens; dämpning; chatter; strukturdynamiska tester; stabilitetsdiagram.;

    Sammanfattning : Chatter vibration is a common problem for the manufacturing industry that limits the productivity, accuracy and surface quality of machined parts. This study is focused on the out of process methods, such as Stability Lobe Diagrams (SLD), that ensure the selection of the optimal cutting parameters in which the machining process is stable.
