  1. 16. Assessing the Eco-efficiency of Swedish Crop Farms and the Role of Subsidies : a Directional Distance Function Approach

    Master-uppsats, SLU/Dept. of Economics

    Författare :Therese Ratilla; [2023]
    Nyckelord :Swedish crop farmers; CAP subsidies; FADN; stochastic frontier analysis; multi-output; one-step approach;

    Sammanfattning : The agriculture sector’s contribution to global greenhouse gas (GHG) emissions and its increasing vulnerability to the effects of climate change warrants assessments considering not only on-farm productivity but also the industry’s environmental sustainability. Utilizing the concept of eco-efficiency, this study analyzes the environmental performance of Swedish crop farms by incorporating farm-level GHG emissions as an undesirable output in the production function.

    Sammanfattning : Gaze estimation, a vital component in numerous applications such as humancomputer interaction, virtual reality, and driver monitoring systems, is the process of predicting the direction of an individual’s gaze. The predominant methods for gaze estimation can be broadly classified into intrusive and nonintrusive approaches. LÄS MER

  5. 19. Optimization over nonnegative matrix polynomials

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Daniel Cederberg; [2023]
    Nyckelord :Proximal methods; nonnegative polynomials; Bregman proximal operator; Itakura-Saito distance; spectral estimation; functional connectivity analysis.;

    Sammanfattning : This thesis is concerned with convex optimization problems over matrix polynomials that are constrained to be positive semidefinite on the unit circle. Problems of this form appear in signal processing and can often be solved as semidefinite programs (SDPs). LÄS MER

    Sammanfattning : Battery electric trucks (BETs) offer environmental benefits in terms of reduced carbon emissions and enhanced energy efficiency but have been challenged with economic viability compared to conventional internal combustion engine trucks (ICETs) caused by substantial acquisition costs, limited charging infrastructure, and concerns regarding range and payload capacity.  Previous studies focus on TCO at the vehicle or policy level but overlook the system and firm-level impacts.
