  1. 26. The effect of imperfect resource conversion and recurring perturbations on byproduct cross- feeding chains in digital communities

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Filippa Frejborg; [2021]
    Keywords : byproduct cross-feeding; cross-feeding interactions; digital evolution; digital organisms; gut microbiome; recurring perturbations; resource conversion;

    Abstract : The gut microbiome plays a vital role in human health. Disturbances of this microbial system is associated with diseases such as obesity and inflammatory bowel disease. In populations of microbial species, many organisms partake in byproduct cross-feeding interactions, where byproducts from one organism are consumed by other microbes. READ MORE

    University essay from SLU/Dept. of Animal Environment and Health

    Author : My Strömgren; [2021]
    Keywords : betningsbeteende; brand; nötkreatur; naturbete; obränt bete; bränt bete;

    Abstract : Habitats worldwide have undergone changes which have had effects on the living conditions for many species. Some landscapes have opened up due to agriculture, others have changed into fragmented monocultural habitats due to forestation. READ MORE

  4. 28. Learning a Reactive Task Plan from Human Demonstrations : Building Behavior Trees using Learning from Demonstration and Planning Constraints

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Oscar Gustavsson; [2021]
    Keywords : Behavior Trees; Learning from Demonstration; Robotics; Robot learning; Human-robot interaction; Beteendeträd; Inlärning från Demonstrationer; Robotik; Robotinlärning; Människa- robotinteraktion;

    Abstract : Robot programming can be an expensive and tedious task and companies may have to employ dedicated staff. A promising framework that can alleviate some of the most repetitive tasks and potentially make robots more accessible to non-experts is Learning from Demonstration (LfD). READ MORE

  5. 29. Model verification and common mode current analysis of grid connected three phase two level converters

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Simon Lindvall; Richard Haraldsson; [2021]
    Keywords : active filter; EMC; EMI; converter; common mode; differential mode; shunt active filter; parasitic elements; Technology and Engineering;

    Abstract : In this Master’s thesis an in-depth model of a shunt active filter for high frequency analysis is constructed. The purpose is to enable analysis of higher frequency behavior reaching 1MHz. Using the high frequency model, common mode currents can be simulated. READ MORE
