  1. 16. Adaptive Concrete 3D Printing Based on industrial Robotics

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Ruiming Hu; [2021]
    Nyckelord :Additive Manufacture; 6-Axis Robot; Point Cloud; Self-Compensation; Additiv tillverkning; 6-axlig robot; punktmoln; självkompensation;

    Sammanfattning : Additive manufacturing, also known as 3D printing is the construction of a three-dimensional object from 3D CAD model. The process includes that material depositing, joining or solidifying using computer control. It is getting widely used in many fields, such as architecture and civil engineering, industry and even medical fields. LÄS MER

  3. 17. Systems of linear nonautonomous differential equations - Instability and eigenvalues with negative real part

    Kandidat-uppsats, Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Författare :Jenny Riesbeck; [2020]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : For an autonomous system of linear differential equations we are able to determine stability and instability with classical criteria, by looking at the eigenvalues. If the system is stable, all the eigenvalues have negative real part and if the system is unstable, there exist at least one eigenvalue with positive real part. LÄS MER

  4. 18. Location decisions regarding forest plantations in Brazil : Which aspects are important to actors in the Brazilian tree industry?

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Katarina Nilsson Lannerstedt; [2020]
    Nyckelord :Eucalyptus; sustainable development; land use; decision-making; policy; legislation; independent forest certification; economic sustainability; environmental sustainability; social sustainability;

    Sammanfattning : Brazilian productive forest plantations and sustainability is a continuous subject of debate, since such forest plantations constitute an increasing proportion of the Brazilian forest cover, and because of documented instances where some establishments have resulted in negative impacts on local ecosystems and communities. Meanwhile, balancing economic, environmental and social sustainability is becoming an important concern in industrial decision-making given the increasing importance of the global sustainability goals.

  5. 19. Robotic Hand Controlled by Glove Using Wireless Communication

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :MEHNAZ KAZI; MICHELLE BILL; [2020]
    Nyckelord :Mechatronics; Robotic Hand; Wireless Control; Mekatronik; Robothand; Trådlös Kontroll;

    Sammanfattning : The interest in the research and development of humanoid robots has been steadily growing in recent years. The application of such robotic systems are many and wide. In this bachelor’s thesis in mechatronics one such robotic system was built in the form of a hand. LÄS MER

  7. 20. Utveckling av ett pressverktyg

    Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Delic Nihad; [2020]
    Nyckelord :Pressverktyg; Produktionsteknik;

    Sammanfattning : I detta arbete undersöks det om det går att plastiskt forma en tunn plåt där ett tredimensionellt kärl formas med hjälp av ett pressverktyg, därefter undersöks möjligheten att förenkla tillverkningssättet som ska leda till bättre arbetsförhållande för maskinoperatör. Det nuvarande kärlet tillverkas på ett föråldrat sätt, där deloperationer utförs separat av varandra på flera manuella pressar, vilket orsakar hög arbetsbelastning på pressoperatören. LÄS MER
