    Forskning redogoĢˆr foĢˆr att foĢˆretag som boĢˆrsnoteras i genomsnitt underprissaĢˆtts. Syftet med studien var att undersoĢˆka skillnaden i underprissaĢˆttning mellan innovativa- och icke-innovativa foĢˆretag i samband med boĢˆrsnoteringar paĢŠ marknadsplatserna Aktietorget och StockholmsboĢˆrsen. Populationen bestod av 258 foĢˆretag som boĢˆrsnoterades mellan 1 januari 2006 och 10 april 2018. Studien tog stoĢˆd i teorin om informationsasymmetri samt signalteorin foĢˆr att foĢˆrklara underprissaĢˆttningen hos foĢˆretagen. Sambanden undersoĢˆktes genom en OLS- regression bestaĢŠende av en enkel- och en multipel regression. Resultatet visade att innovativa foĢˆretag underprissatts mer aĢˆn icke-innovativa foĢˆretag och var statistiskt signifikant foĢˆr den enkla regressionen. Studiens resultat tolkades delvis i enlighet med tidigare forskning och indikerade att informationsasymmetrin var hoĢˆgre foĢˆr innovativa foĢˆretag.

    On-line Powerplant Control using Near-InfraRed Spectroscopy : OPtiC-NIRS, REPORT 2021:746

    Near InfraRed Spectroscopy (NIRS) offers rapid on-line analysis of biomass feedstocks and can be utilized for process control of biomass- based combined heat and power plants. Within the OPtiC-NIRS project we have carried out a full-scale on-site testing of different NIRS for online powerplant control at the facilities of MaĢˆlarenergi and Eskilstuna StraĢˆngnaĢˆs Energi och MiljoĢˆ.Ā  The project has been focused on developing and testing robust NIRS soft-sensors for fuel higher heating value and composition (incl. moisture, components such as recycle wood and glass, different type of plastics and ash) and combining them with dynamic models for on-line feed-forward process monitoring and control. Expected benefits include reduced risk of agglomeration and pollutant emissions formation as well as improved production control. A longer-term potential and ambition is to be able to identify the fossil content in municipal waste fuel, which can hopefully be addressed in a follow-up study.Ā These are the results and conclusions of a project, which is part of a research programme run by Energiforsk.
