  1. 6. Extremal eigenvalues and geometry of quantum graphs

    Författare :Andrea Serio; Pavel Kurasov; Annemarie Luger; Evans Harrell; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum graphs; spectral estimates; trace formula; Euler characteristic; Mathematics; matematik;

    Sammanfattning : This thesis consists of four papers concerning topics in the spectral theory of quantum graphs, which are differential operators on metric graphs.In paper I we present a family of graphs with an arbitrary number of cycles for which a certain eigenvalue upper estimate is sharp.

  3. 7. Simulation Modelling of a Shift to Service-Based Offerings : Resource efficiency and operational implications in the context of the circular economy

    Författare :Raphael Wasserbaur; Tomohiko Sakao; Erik Sundin; Steve Evans; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource efficiency; resource effectiveness; circular economy CE ; sociotechnical systems; systems thinking; simulation; product service system PSS ; system dynamics;

    Sammanfattning : The unsustainable levels of resource use and emissions of our economies and their threat to future generations are core issues of our time. The circular economy (CE) conceptualises a different type of economy that is restorative and regenerative by design and aims to keep products, components and materials at their highest utility and value at all times, distinguishing between technical and biological cycles.

  4. 8. Relatedness through kinship : the importance of family co-occurrence for firm performance

    Författare :Evans Korang Adjei; Urban Lindgren; Rikard Eriksson; Rodrigo Basco; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; proximity dimension; agglomeration economies; family; family co-occurrence; family firm; region; firm performance; regional development; entrepreneurial capital; localized learning; Sweden; Social and Economic Geography; kulturgeografi;

    Sammanfattning : The aim of the thesis is to analyse the effects of family co-occurrence and past familial relationships (inherited entrepreneurial abilities) on firm performance. This aim is motivated by the contemporary arguments that social relations (e.g. family ties) are important in the analysis of today’s space economy. LÄS MER

  5. 9. Edge Precoloring Extension of Trees

    Författare :Fikre Bogale Petros; Carl Johan Casselgren; Armen Asratian; Lars-Daniel Öhman; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Given a set of k colors and a graph G with a subset S of precolored edges (a partial k-edge coloring of G), we consider the problem of determining whether G has a proper edge coloring of G with the same k colors (an extension of the partial coloring) where the colors of edges in S are not changed. If such a coloring exists, then the partial k-coloring is called extendable. LÄS MER

  7. 10. Why should physicians read? : Understanding clinical judgement and its relation to literary experience

    Författare :Rolf Ahlzén; Martyn Evans; Jane Macnaughton; Karlstads universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Is literary experience of any practical relevance to the clinician? This is the overall question addressed by this investigation, which starts by tracing the historical roots of scientific medicine. These are found to be intimately linked to a form of rationality associated with the scientific revolution of the 17th century and with “modernity”. LÄS MER
