1. 1. Digital Geometry, Combinatorics, and Discrete Optimization

   Författare :Shiva Samieinia; Christer Kiselman; Rikard Bøgvad; Rémy Malgouyres; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Digital geometry; Khalimsky topology; Khalimsky plane; Khalimsky-continuous function; digital straight line segments; discrete optimization; discrete convexity; integral convexity; lateral convexity; marginal function; MATHEMATICS; MATEMATIK; Mathematics; matematik;

   Sammanfattning : This thesis consists of two parts: digital geometry and discrete optimization. In the first part we study the structure of digital straight line segments. We also study digital curves from a combinatorial point of view. LÄS MER

3. 2. Marginal cost pricing of electricity

   Författare :Göran Edsbäcker; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : The discipline is economics and the phenomenon is the power system. The purpose of this system is to produce, transmit and consume electricity in such a way that the sum of consumers' and suppliers' surplus is maximized. This is accomplished by the means of marginal cost pricing. LÄS MER

4. 3. Function and Regulation of B-cell Subsets in Experimental Autoimmune Arthritis

   Författare :Anna-Karin E. Palm; Sandra Kleinau; Susanna Cardell; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; B cells; marginal zone; autoimmune arthritis; spleen; lymph node; antigen presentation; Fc gamma receptor IIb; complement receptors 1 and 2; mast cells; Biologi med inriktning mot molekylär immunologi; Biology with specialization in Molecular Immunology;

   Sammanfattning : B lymphocytes play a significant role in autoimmune arthritis, with their function stretching beyond autoantibody production to cytokine secretion and presentation of autoantigen. However, the involvement and activation of different B-cell subset in the autoimmune response is not fully clear. LÄS MER

5. 4. Modelling Bidding Behaviour in Electricity Auctions : Supply Function Equilibria with Uncertain Demand and Capacity Constraints

   Författare :Pär Holmberg; Nils Gottfries; Chuan-Zhong Li; Mats Bergman; David Newbery; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business and economics; supply function equilibrium; asymmetry; uniqueness; oligopoly; capacity constraint; uniform-price auction; pay-as-bid auction; discriminatory auction; wholesale electricity market; Ekonomi; Business and economics; Ekonomi;

   Sammanfattning : In most electricity markets, producers submit supply functions to a procurement uniform-price auction under uncertainty before demand has been realized. In the Supply Function Equilibrium (SFE), every producer commits to the supply function that maximises his expected profit given the bids of competitors. LÄS MER

7. 5. Essays on Consumption : - Aggregation, Asymmetry and Asset Distributions

   Författare :Mårten Bjellerup; Jan Ekberg; Katarina Juselius; Växjö universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Aggregate consumption; Aggregation; Asymmetry; Wealth distribution; Income distribution; Concavity; Permanent Income Hypothesis; Buffer stock saving; Precautionary saving; consumption; saving; Euler equation; error correction; skew-t distribution; gamma distribution; dispersion; non-linear model; durable goods; nondurable goods; household level data; consumption function; marginal propensity to consume; current resources; consumption expenditure; life-cycle model; univariate test; multivariate test; Sweden; Economics; Nationalekonomi; Economics; Nationalekonomi;

   Sammanfattning : The dissertation consists of four self-contained essays on consumption. Essays 1 and 2 consider different measures of aggregate consumption, and Essays 3 and 4 consider how the distributions of income and wealth affect consumption from a macro and micro perspective, respectively.
