1. 1. Modelling the transient response of windings, laminated steel coresand electromagnetic power devices by means of lumped circuits : With special reference to windings with a coaxial insulation system

   Författare :Pär Holmberg; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Transient response; frequency response; electromagnetic transient analysis; circuit modeling; eddy currents; skin effect; windings; coils; magnetic cores; cables; electric machines; rotating electric machines; transformers; Fysik; Physics; Fysik; Electricity; Esp The Study Of Transients and Discharges; elektricitetslära; ssk studiet av transienter och urladdning;

   Sammanfattning : Electromagnetic transients impinging on electromagnetic power devices - such as electric machines, transformers and reactors - can stress the design severely. Thus the magnitudes of the transients are often decisive for the design of the devices. Further, the operation of a device can be transient in itself. LÄS MER

4. 3. 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

5. 4. Synthesis of Molecular Probes for Exploring the Human Consciousness, 5-HT7 Ligands and Salvinorins

   Författare :Pär Holmberg; Anders Karlén; Adolf Gogoll; Anette Johansson; Christer Sahlberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; serotonin system; opioid system; selective 5-HT7 agonist; 3-aminchromans; salvinorin A; selective kappa opioid receptor; mental disorders; consciousness; regioselective oxidation; enzymatic kinetic resolution; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi;

   Sammanfattning : In this study, we have addressed the serotonergic and the opioid system within the CNS. Both systems are of outmost importance in the etiology of disease states, especially mental disorders. LÄS MER

7. 5. A Co-Simulation Tool Applied to Hydraulic Percussion Units

   Författare :Håkan Andersson; Daniel Leidermark; Kjell Simonsson; Joakim Holmberg; Pär Jonsén; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In this dissertation, a co-simulation tool is presented that is meant to comprise a more comprehensive environment for modelling and simulation of hydraulic percussion units, which are used in hydraulic hammers and rock drills. These units generates the large impact forces, which are needed to demolish concrete structures in the construction industry or to fragment rock when drilling blast holes in mine drifting. LÄS MER
