  1. 1. Explanation and deduction : a defence of deductive chauvinism

    Författare :Henrik Hållsten; Matti Sintonen; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Deductive explanation; Statistical explanation; Chances; Propensities; Probabilities; Sine qua non; Probabilistic causality; Indeterminism; Ideal explanatory text; Explanatory information; Explanatory sketches; Dynamic systems; Chaotic systems; Approximate solutions; Argument generating procedure. Central figures: Hempel; Coffa; Salmon; Railton; Humphreys; Kitcher; Poincaré; Suppes; Lorenz; Hénon.; Theoretical Philosophy; teoretisk filosofi;

    Sammanfattning : In this essay I defend the notion of deductive explanation mainly against two types of putative counterexamples: those found in genuinely indeterministic systems and those found in complex dynamic systems. Using Railton's notions of explanatory information and ideal explanatory text, deductivism is defended in an indeterministic setting. LÄS MER

  3. 2. Determination of stellar ages and star formation histories - a Bayesian approach With an application to nearby F and G stars

    Författare :Bjarne Rosenkilde Jørgensen; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomi; Astronomy; Galaxy evolution; Statistical methods; Stellar evolution; Data analysis;

    Sammanfattning : In order to understand the formation and evolution of the Galaxy it is imperative to know when different components formed. This means at the most basic level that we need to know the ages of stars. The present work demonstrates the many problems inherent in determining the ages of stars through comparison with stellar evolutionary models. LÄS MER

  4. 3. Modeling of inorganic ions in aqueous solution

    Författare :Vidar Aspelin; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molekylsimulering; statistisk mekanik; termodynamik; oorganiska joner; vattenlösningar; Kirkwood-Buff-teori; beräkningar av fri energi; molecular simulation; statistical mechanics; thermodynamics; inorganic ions; aqueous solutions; Kirkwood-Buff theory; free energy calculations;

    Sammanfattning : Essentially all chemical processes and reactions occurring in the environment take place in the presence of ions. In water, ions set the conditions for how other dissolved particles interact. Ions are also directly involved in chemical reactions affecting the climate such as ozone depletion. LÄS MER

  5. 4. Modelling of Solid Oxide Fuel Cells Applied to the Analysis of Integrated Systems with Gas Turbines

    Författare :Azra Selimovic; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; statistical physics; plasma; plasmas; Gaser; fluiddynamik; Termisk teknik; termodynamik; Gases; fluid dynamics; applied thermodynamics; Thermal engineering; Hybrid Cycles; Gas Turbines; Mathematical Modelling; Electrochemistry; Fuel Cells; Solid Oxide Fuel Cells; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; gravitation; statistisk fysik; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; relativity;

    Sammanfattning : Solid oxide fuel cells (SOFCs), working at high temperatures with an incomplete fuel oxidation process, have become an interesting candidate for combination with conventional power generation technology, such as gas turbines, in order to develop power plants that are both functional and efficient. An absolute condition for successful analysis and optimisation of such plants is the existence of reliable simulation tools. LÄS MER

  7. 5. Essays on Household Behavior and Time-Use

    Författare :Daniel Hallberg; Daniel S. Hamermesh; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Time-use; Household behavior; Slutsky matrix; Income-pooling; Household labor supply; Child care; Family economics; Simultaneous equation system; Process benefits; Synchronous leisure; Working hours; Togetherness; Statistical matching; Aggregation bias; House price; Volume of trade; Search; Nationalekonomi; Tidsanvändning; Hushållsbeteende; Slutsky matris; Inkomstsammanslagning; Hushållets arbetsutbud; Barnomsorg; Familjeekonomi; Simultana ekvationssystem; Aktivitetsnytta; Samtidig fritid; Arbetstider; Samhörighet; Statistisk matching; Aggregeringsbias; Huspriser; Omsättningsvolym; Sökning.; Economics; Nationalekonomi; nationalekonomi; Economics;

    Sammanfattning : Essay 1 studies the household's decision to supply labor and tests if the so-called unitary model holds. What is subject to a test is the resulting symmetry of the Slutsky matrix, i.e., that the compensated cross-wage effects are equal. LÄS MER
