  1. 21. A comparative cost analysis of conventional wrought steel and powder metallurgy (PM) gear manufacturing technologies

    Författare :Babak Kianian; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gear manufacturing; Manufacturing cost analysis; Powder metallurgy PM ; Press and sintering P S ; Wrought steel conventional gear manufacturing; Decision support system DSS ; Sustainability; Sustainable production SP ; Automotive Industry;

    Sammanfattning : The transportation industry landscape is going through a massive transformation due to trends such as autonomous and electrified vehicles. The electrification trend has already started to display its ample influence on the automotive industry. LÄS MER

  3. 22. History Reduction Techniques for Simulation of Additive Manufacturing and Physically based Material Modeling

    Författare :Andreas Malmelöv; Andreas Lundbäck; Bijish Babu; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : In this thesis, finite element (FE) simulations of additive manufacturing (AM) and physically based material modeling are presented. AM is a process where the component is built layer-wise. LÄS MER

  4. 23. Adhesion and Friction - a Study on Tactility

    Författare :Kenneth Duvefelt; Ulf Olofsson; Emile Van Der Heide; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesion; finger; friction; humidity; material; model; tactile friction; tactility; Machine Design; Maskinkonstruktion;

    Sammanfattning : Although we are surrounded by hundreds of surfaces we can still distinguish them from each other simply by touch. The tactile information, interpreted by our brain and given by our fingers, is precise, but to put words to the sensation is very difficult — is it smooth, sticky or harsh? We do not only perceive surfaces differently, we also describe them in our own way. LÄS MER

  5. 24. Interactions of methane and carbon monoxide with platinum - Supported catalysts and chemical sensors

    Författare :Elin Becker; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Periodic operation In situ spectroscopy; XAS; CO; Sensing mechanism; Low-temperature activity; XANES; Pt; Environmental catalysis; Support material; CH4; Chemical sensors;

    Sammanfattning : This thesis aims at increasing the understanding of the interactions of methane and carbon monoxide with platinum in connection to catalysis and sensor technology for emission control. Specifically, the low-temperature oxidation of methane and carbon monoxide over supported platinum catalysts and the sensor response mechanism towards CO of platinum-based chemical field effect sensors were studied.

  7. 25. ”Man vill ju klara sig själv” : Studievardagen för studenter med Asperger syndrom i högre utbildning

    Författare :Ann Simmeborn Fleischer; Mats Granlund; Berth Danermark; Margareta Adolfsson; Anders Möller; Jönköping University; []
    Nyckelord :Asperger syndrome; Higher education; everyday student-life; support; catch-22; struggle; alienation; stigmatization; dramaturgical perspective; university; relatives; coordinator; disability; Code set; ICF; Asperger syndrom; högre utbildning; studievardag; studenter med Asperger syndrom i behov av stöd; stöd; moment-22; kamp; alienation; stigmatisering; dramaturgi; högskola; universitet; anhöriga; samordnare; Code set; ICF; kommunikationsverktyg;

    Sammanfattning : SammanfattningSedan början av 2000-talet har det skett en markant ökning av studier gällande barn och ungdomar och Autism. Dock är det så att den mesta forskningen fortfarande är inom det medicinska området. Endast ett fåtal av studierna rör vuxna med Asperger syndrom (AS) som studerar på högskola/universitet. LÄS MER
