  1. 21. On cutting tool resource management

    Författare :Ana Esther Bonilla Hernández; Tomas Beno; Claes Fredriksson; Leonardo De Chiffre; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CAM programming; Cutting data; Lean; Manufacturing; Material Removal Rate; Optimization; Tool life; Tool utilization; Tool wear; Sustainability; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : The search for increased productivity and cost reduction in machining can be interpreted as desire to increase the Material Removal Rate, , and maximize the cutting tool utilization. The CNC process is complex and involves numerous constraints and parameters; ranging from tolerances to machinability. LÄS MER

  3. 22. Model-Based Verification of Dynamic System Behavior against Requirements : Method, Language, and Tool

    Författare :Wladimir Schamai; Peter Fritzson; Hans Vangheluwe; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Modeling and simulation of complex systems is at the heart of any modern engineering activity. Engineers strive to predict the behavior of the system under development in order to get answers to particular questions long before physical prototypes or the actual system are built and can be tested in real life.

  4. 23. Erkännandets Janusansikte : Det sociala kapitalets betydelse i arbetslivskarriärer

    Författare :Caroline Tovatt; Anders Neergaard; Anna-Liisa Närvänen; Aleksandra Ålund; Lennart Svensson; Linköpings universitet; []
    Nyckelord :Social capital; social networks; recruitment; working life; working life stories; Bourdieu; Socialt kapital; socialt nätverk; rekrytering; arbetsliv; arbetslivsberättelser; kvalitativ forskning; Bourdieu;

    Sammanfattning : I denna studie undersöks de informella processerna i rekryteringen, speciellt innebörden av olika former av socialt kapital. I fokus står de värden som tillskrivs utbildningar, arbetslivserfarenheter och kontakter. Det uttrycks genom frågor som hur, var, vem och varför snarare än om lediga tjänster tillsätts via kontakter.

  5. 24. Life Cycle Assessment and Decision Making: Theories and Practices

    Författare :Henrikke Baumann; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle assessment; LCA practice; LCA methodology; LCA modelling; institutionalisation; LCA procedure; life cycle accounting; LCA; systems analysis; decision making;

    Sammanfattning : Life cycle assessment (LCA) has been in use to a varying extent since the late 1960s. The fact that LCA methodology needs further development is a frequently identified barrier to the further application of LCA. Consequently, the literature with suggestions for improving LCA methodology is extensive. LÄS MER

  7. 25. Causes and consequences of life-history variation : The effects of parasites, glucocorticoids, and environmental conditions in the collared flycatcher (Ficedula albicollis)

    Författare :Kevin Fletcher; Lars Gustafsson; Anders Pape Moller; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Collard flycatcher; Haemosporidian blood parasite; glucocorticoid; life history;

    Sammanfattning : Life-history is the study of all the different stages of life that affect reproductive success and survival between the birth and death of an organism. The reproductive output of an organism is constrained by many things including time, resource, disease agents and environmental conditions. LÄS MER
