  5. 24. Structure and function of relaxins

    Författare :Linda M. Haugaard-Kedström; Johan Rosengren; Torleif Härd; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; relaxin; insulin-like peptide; peptide hormone; peptide synthesis and NMR; Organic Chemistry; Organisk kemi;

    Sammanfattning : The relaxin/insulin superfamily is a group of peptide hormones that consists of ten members in human, namely relaxins 1-3, insulin-like peptides (INSL) 3-6, insulin and insulin-like growth factors (IGF) I-II. These peptides have various functions in the body, such as regulating growth, blood glucose levels,  collagen metabolism, germ cell maturation and appetite. LÄS MER

  7. 25. Multivariable Frequency-Domain Identification of Industrial Robots

    Författare :Erik Wernholt; Svante Gunnarsson; Jan Swevers; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Frequency-domain identification; industrial robots; nonparametric identification; nonlinear gray-box identification; multivariable systems; closed-loop identification; Automatic control; Reglerteknik;

    Sammanfattning : Industrirobotar är idag en väsentlig del i tillverkningsindustrin där de bland annat används för att minska kostnader, öka produktivitet och kvalitet och ersätta människor i farliga eller slitsamma uppgifter. Höga krav på noggrannhet och snabbhet hos robotens rörelser innebär också höga krav på de matematiska modeller som ligger till grund för robotens styrsystem. LÄS MER
