  1. 26. Dealing with uncertainty

    Författare :Jonas Clausen Mork; John Cantwell; Till Grüne-Yanoff; Terje Aven; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; safety factor; safety margin; uncertainty factor; uncertainty function; uncertainty; information; risk; risk assessment; risk management; epistemology; science; reasoning;

    Sammanfattning : Uncertainty is, it seems, more or less constantly present in our lives. Even so, grasping the concept philosophically is far from trivial. In this doctoral thesis, uncertainty and its conceptual companion information are studied. Axiomatic analyses are provided and numerical measures suggested. LÄS MER

  3. 27. Influence of Water on Coarse Granular Road Material Properties

    Författare :Jonas Ekblad; Ulf Isacsson; Hervé Di Benedetto; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Highway Engineering; Granulat materials; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : Even though the practical experience of using coarse unbound granular materials is extensive, detailed knowledge on the mechanical and hydraulic behavior is to a large extent lacking. Regarding influence of water on mechanical properties, this is even more pronounced. LÄS MER

  4. 28. Advancements in Firefly Luciferase-Based Assays and Pyrosequencing Technology

    Författare :Jonas Eriksson; KTH; []
    Nyckelord :bioluminescence; osmolytes; glycine betaine; thermostability; firefly luciferase; inorganic pyrophosphatase; inorganic pyrophosphate; Pyrosequencing technology; secondary DNA-structures; Sequenase; Klenow-polymerase; reaction rates; temperature;

    Sammanfattning : Pyrosequencing is a new DNA sequencing method relying on thesequencing-by-synthesis principle and bioluminometric detectionof nucleotide incorporation events. The objective of thisthesis was improvement of the Pyrosequencing method byincreasing the thermal stability of firefly luciferase, and byintroducing an alternative DNA polymerase and a new nucleotideanalog.

  5. 29. Effects of trace elements in biodiesel on the performance of diesel oxidation catalysts in heavy-duty vehicles

    Författare :Jonas Granestrand; Lars Pettersson; Todd J. Toops; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Oxidation catalyst; heavy-duty vehicles; catalyst deactivation; biodiesel; NAP-XPS; XANES; Phosphorus; alkali metals; Pt Pd Al2O3; Chemical Engineering; Kemiteknik;

    Sammanfattning : To reduce net greenhouse gas emissions, a shift towards adoption of biofuels is ongoing in the transport sector. Heavy-duty diesel vehicles are equipped with aftertreatment equipment, comprising of catalysts and filters, and how this equipment is affected by the use of biofuels is not yet fully understood.

  7. 30. Continuous time Graphical Models and Decomposition Sampling

    Författare :Jonas Hallgren; Timo Koski; Blazej Miasojedow; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Two topics in temporal graphical probabilistic models are studied. The topics are treated in separate papers, both with applications in finance. The first paper study inference in dynamic Bayesian networks using Monte Carlo methods. A new method for sampling random variables is proposed. LÄS MER
