  1. 1. Circling the Squares : Radical Innovation and Management Control Systems in the Circular Economy

    Författare :Johan Arekrans; Sofia Ritzén; Rafael Laurenti; Johan Frishammar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; circular economy; innovation; innovation management; sustainability; management control systems; cirkulär ekonomi; innovation; innovationsledning; hållbarhet; kontrollmekanismer; Machine Design; Maskinkonstruktion;

    Sammanfattning : An economic system built upon the sale of tangible goods produced using finite resources is inherently unsustainable. The idea of a Circular Economy (CE) as a viable pathway to sustainability has gained considerable attention from academia, policymakers, and the business community. LÄS MER

    Sammanfattning : Vid analys av vattenprover tagna från t.ex. ett vattendrag betäms halten av olika ämnen. Dessa halter är ofta beroende av vattenföringen. LÄS MER

  5. 4. Analysis of Some Methods for Identifying Dynamic Errors-in-variables Systems

    Författare :Mei Hong; Torsten Söderström; Magnus Jansson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; errors-in-variables; least squares; instrumental variable; maximum likelihood; bias compensated least squares; bias eliminating least squares; Frisch scheme; higher-order statistics; accuracy analysis; periodic data; Signal processing; Signalbehandling;

    Sammanfattning : A system where errors or noises are present on both the inputs and the outputs is called an errors-in-variables (EIV) system. EIV systems appear in industrial and agricultural processes, medical sciences, economical systems, biotechnology, as well as in many other areas. LÄS MER

  7. 5. Fast Algorithms for Integral Equations and Least Squares Identification Problems

    Författare :Stefan Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fast algorithms; Integral equations; Least squares; Identification;

    Sammanfattning : This work is concerned with fast algorithms for integral equations and least squares identification problems.The presentation is divided into three parts. In the first part a fast algorithm for solving systems oflinear equations with a matrix that is alm ost Toeplitz is derived and applied to Fredholm integral equations with stationary kernels. LÄS MER
