  1. 1. Utvärdering av biotopvårdande åtgärder i Grimåsbäcken. En analys av fysikaliska egenskaper och sammansättning av makroevertebrater.

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Björn Andermo; [2024-01-22]
    Nyckelord :Channelized streams; retention; biotope preservation; macroinvertebrates; bottom substrate; woody debris.;

    Sammanfattning : Many streams have been exposed to extensive anthropogenic impact for the benefit of forestry and agriculture. The effects has mainly been channelization characterized by lowered and straightened channels. This homogeneous morphology leads to decreased ability to retain water as well as lost connection to the floodplain. LÄS MER

  3. 2. Do viscous flows slip?

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Björn Sjösvärd; [2023-12-21]
    Nyckelord :Mathematics; partial differential equations; multivectors; Hodge de-compositions; the Stokes equation; Hodge boun;

    Sammanfattning : In this thesis, the Stokes equation is discussed and solved under different boundary conditions. The Stokes equation governs the flow of viscous liquids, for example honey or syrup. The first chapters in the thesis provides an introduction to multivector algebra and analysis, with the aim of presenting the concept of Hodge decompositions. LÄS MER

  4. 3. Connecting with and Supporting Grassroots Innovators - A Comparative Case Study

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Björn Jakobsson; [2023-07-20]
    Nyckelord :Grassroot innovation; innovation hubs; incubation; acceleration; supporting innovators; developing innovation systems;

    Sammanfattning : This paper examined how innovation hubs are identifying and connecting with grassroots innovators, and how they can support grassroots innovators. Grassroots innovators are typically entrepreneurs from poor communities. LÄS MER

  5. 4. The Impact of Share Repurchases on Stock Liquidity During Market Distress

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Björn Landelius; Kasper Lindqvist; [2023-07-04]
    Nyckelord :Share repurchase; Stock liquidity; Market distress; Information asymmetry; Competing market;

    Sammanfattning : Since stock repurchases were first introduced in the late 1960 its growth has been significant. This has led to increasing interest among researchers regarding the motives behind them and their post-effects. While stock repurchase research is extensive, the focus on the effect of stock repurchases on liquidity is limited. LÄS MER

  7. 5. Optimizing Quantum Computer Simulations With Data Compression & GPU Acceleration

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Erik Ljung; Darko Petrov; Felix Bråberg; Björn Forssén; Beata Ringmar; Jonas Hedlund; [2023-03-03]
    Nyckelord :;

    Sammanfattning : Simulating quantum computers involves high memory usage and often long execution times. For that reason the purpose of this project was to analyze whether data compression and GPU acceleration can be used to run simulations with more qubits than previously allowed. LÄS MER
