  1. 1. Eco-Efficiency of 35 sectors of Sweden: A Stochastic Frontier Analysis

    University essay from Umeå universitet/Nationalekonomi

    Author : Tehmina Batool; [2023]
    Keywords : ;

    Abstract : This paper analyzed the eco-efficiency of 35 sectors in Sweden by using an outputoriented Stochastic Frontier Analysis (SFA) model. In the setup of the model, the total output of each sector was used as a good output, whereas Carbon dioxide (𝐶𝑂2), Nitrogen oxide (𝑁𝑂𝑥) and Carbon monoxide (CO) emissions were used as a bad output.

  4. 3. Inverse source modeling of roll induced magnetic signature

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Erik Thermaenius; [2022]
    Keywords : inverse modeling; inverse; modeling; magnetic; signature; source modeling; tikhonov; roll; magnetic silencing; regularization; regularisation; induction; dipole; dipoles; Helmholtz; inversmodellering; magnetisk; signatur; källmodellering; rullning; rullningsinducerad; regularisering; dipol; dipoler;

    Abstract : Vessels constructed in electrically conductive materials give rise to frequency-dependent, induced magnetic fields when waves of water cause them to roll in the Earth's magnetic field. These fields, typically referred to as roll-induced magnetic vortex fields, are a component of the ship's overall signature, where signature refers to measurable quantities which can reveal or identify objects.

  5. 4. Persistence of Preference- Based Customer Segments : An investigation of cluster evolution

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

    Author : Sara Almström; [2021]
    Keywords : Cluster evolution; Cluster persistence; Customer segmentation; Streaming services; Video-on-demand; Television; Kluster-evolution; Kluster-beständighet; Kundsegmentering; Strömningstjänster; Video-på-begäran; Television;

    Abstract : Clustering is a technology within unsupervised learning with a wide range of applications. Several of these applications use data that change over time, which makes clusters’ persistence of interest. One among these employments of clustering time-variant data is preference based customer segmentation. READ MORE

  6. 5. Hot Commodity? The Commodity Currency Hypothesis and the Financialisation of Commodity Markets

    University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Author : Hannes Ludvigsson; Erik Ekelund; [2021]
    Keywords : Commodity Currency Hypothesis; Exchange Rates; Time Series Analysis; Granger-causality;

    Abstract : Movements in the commodity markets can have profound effects on the global economy by affecting the cost of food, metal, and energy goods. As such, the prospect of predicting commodity price fluctuations, thereby allowing for better inflation control, production planning and even humanitarian aid, has long generated great interest.
