1. ## 1. Numerical Accident Reconstructions : A Biomechanical Tool to Understand and Prevent Head Injuries

Sammanfattning : Traumatic brain injuries (TBIs) are a major health and socioeconomic problem throughout the world, with an estimated 10 million deaths and instances of hospitalization annually. Numerical methods such as finite element (FE) methods can be used to study head injuries and optimize the protection, which can lead to a decrease in the number of injuries. LÄS MER

2. ## 2. Turbulent jets in confined spaces : application in mixing ventilation: experimental and numerical studies

Sammanfattning : The basis of mixing ventilation is the airflow supply to the room by means of jets initiatedfrom the ventilation diffusers. To avoid the draught problem, the design of mixing ventilationmakes uses the throw term, which is defined as the distance to the supply air terminal inwhich the jet centreline mean velocity is decreased to a given value.

3. ## 3. Heat and Mass Transfer in Built Structures - Numerical Analyses

Sammanfattning : Heat and mass transport processes are often present simultaneously in built structures in building applications. The emphasis of this thesis is to contribute to knowledge about predicting the effects of combined heat and mass transport in built structures. LÄS MER

4. ## 4. The Theory of Polynomial Functors

Sammanfattning : Polynomial functors were introduced by Professors Eilenberg and Mac Lane in 1954, who used them to study certain homology rings. Strict polynomial functors were invented by Professors Friedlander and Suslin in 1997, in order to develop the theory of group schemes. LÄS MER

5. ## 5. 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]

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
