  1. 11. Redox models in chemistry : A depiction of the conceptions held by secondary school students of redox reactions

    Författare :Lise-Lotte Österlund; Margareta Ekborg; Anders Berg; Christiane Funk; Astrid Bulte; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; science education; redox reaction; model; inorganic chemistry; organic chemistry; biochemistry; students conceptions; textbook; Other chemistry; Övrig kemi; didactics of chemistry; kemididaktik;

    Sammanfattning : According to previous research, students show difficulties in learning redox reactions. By the historical development different redox models exist to explain redox reactions, the oxygen model, the hydrogen model, the electron model and the oxidation number model. LÄS MER

  2. 12. Effect Oriented Planning in Military Mission Support Systems : Models and Heuristic Approaches

    Författare :Kristian Lundberg; Kaj Holmberg; Torbjörn Larsson; Stefan Engevall; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Today there are many aspects of model based planning, probably much more than for just 20 years ago. Today data is not the problem, data is everywhere, but the big issue is to understand how to gain advantage of data in decision making - a growing focus is now on modeling!This work is devoted to this task and can be seen as a three part study.

  3. 13. Connect : Modelling Learning to Facilitate Linking Models and the Real World trough Lab-Work in Electric Circuit Courses for Engineering Students

    Författare :Anna-Karin Carstensen; Jonte Bernhard; Christian Kautz; Linköpings universitet; []
    Nyckelord :Engineering Education; Engineering Education Research; Key concepts; Labwork; Laplace Transforms; Learning; Learning of a Complex Concept; Learning to model; Modelling learning; Models; Practical Epistemologies; Threshold concepts; Variation Theory;

    Sammanfattning : A recurring question in science and engineering education is why the students do not link knowledge from theoretical classes to the real world met in laboratory courses.Mathematical models and visualisations are widely used in engineering and engineering education. LÄS MER

  4. 14. Linear models for multiscale materials simulations : Towards a seamless linking of electronic and atomistic models for complex metal oxides

    Författare :Akshay Krishna Ammothum Kandy; Peter Broqvist; Jolla Kullgren; Eddie Wadbro; Ben Hourahine; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Force fields; Electronic structure calculations; CCS; DFTB; CCS Q; repulsive fitting; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : Multiscale modelling approaches, connecting data from electronic structure calculations all the way towards engineering continuum models, have become an important ingredient in modern materials science. Materials modelling in a broader sense is already amply used to address complex chemical problems in academic science, but also in many industrial sectors. LÄS MER

  5. 15. Dynamic Abstraction for Interleaved Task Planning and Execution

    Författare :Per Nyblom; Patrick Doherty; Lars Karlsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Artificial Intelligence; Dynamic Abstraction; Task Planning; Automatic Model Construction; Meta-modelling; Computer science; Datavetenskap;

    Sammanfattning : It is often beneficial for an autonomous agent that operates in a complex environment to make use of different types of mathematical models to keep track of unobservable parts of the world or to perform prediction, planning and other types of reasoning. Since a model is always a simplification of something else, there always exists a tradeoff between the model’s accuracy and feasibility when it is used within a certain application due to the limited available computational resources.
