  1. 31. On the estimation of ligand binding affinities

    Författare :Samuel Genheden; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; binding affinities protein-ligand complexes; host-guest complexes; MM GBSA; MM PBSA; LIE; PDLD s-LRA; alchemical methods; sampling; solvation; drug design;

    Sammanfattning : A method to accurately estimate the binding affinity of a small molecule to a receptor would be indispensable in numerous fields. For instance, most drugs exert their action by binding to a macromolecule target. Thus, a lot of time and resources could be saved in drug design by predicting affinities by computer programs.

  3. 32. Estimation of Nonlinear Greybox Models for Marine Applications

    Författare :Fredrik Ljungberg; Martin Enqvist; Svante Gunnarsson; Håkan Hjalmarsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : As marine vessels are becoming increasingly autonomous, having accurate simulation models available is turning into an absolute necessity. This holds both for facilitation of development and for achieving satisfactory model-based control. LÄS MER

  4. 33. Analyses and Applications of the Peaceman--Rachford and Douglas--Rachford Splitting Schemes

    Författare :Erik Henningsson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Splitting methods are widely used as temporal discretizations of evolution equations. Such methods usually constitute competitive choices whenever a vector field can be split into a sum of two or more parts that each generates a flow easier to compute or approximate than the flow of the sum.

  5. 34. Proportionalitetsbegreppet i den svenska gymnasiematematiken – en studie om läromedel och nationella prov : [The Concept of Proportionality in the Swedish Upper Secondary School Mathematics – a Study of Textbooks and National Examinations]

    Författare :Anna L.V. Lundberg; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Proportion; upper secondary school; textbooks; national course tests; curriculum; ATD; The anthropological theory of the didactics; missing value; numerical comparison; Qualitative prediction and comparison Nyckelord sv : Proportionalitets begreppet; proportionalitet; Matematik A; gymnasiet; läromedel; nationella prov; läroplaner; Lpf 94; ATD; reguladetri; saknat värde; missing value; numerical comparison; Qualitative prediction and comparison;

    Sammanfattning : Proportionalitet är ett centralt begrepp i skolmatematiken. Begreppet introduceras i de lägre stadierna och återkommer i så gott som samtliga kurser från årskurs 9 tillsista kursen på gymnasiet. Det övergripande syftet med denna studie är att undersöka hur det matematiska begreppet proportionalitet hanteras i den svenska gymnasieskolan. LÄS MER

  7. 35. Power System Damping - Structural Aspects of Controlling Active Power

    Författare :Olof Samuelsson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics and Electrical technology; controller interaction; mode controllability; mode observability; mechanical equivalent; linear differential-algebraic equations; modal analysis; active power; power system damping; electro-mechanical oscillations; Elektronik och elektroteknik; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Environmental and economical aspects make it difficult to build new power lines and to reinforce existing ones. The continued growth in demand for electric power must therefore to a great extent be met by increased loading of available lines. LÄS MER
