Dataspelande inte orsak till dåliga skolresultaten

Vi forskare som står bakom den här artikeln har tidigare kritiserat debatten kring nät- och dataspelsberoende för att vara missvisande. Vi menar att nättid eller dataspelande i sig inte har något att göra med vare sig försämrade studieresultat eller rubbad dygnsrytm. Forskningen har på senare år antytt att överdrivet dataspelande bör ses som ett uttryck för underliggande problem, på samma sätt som

Modeling of plasticity at large strains

This thesis is concerned with various aspects of the constitutive modeling of plasticity. Both theoretical issues and issues related to the numerical implementation of the constitutive models are addressed. An approach to the modeling of kinematic hardening plasticity when large strains are present, taking the microstructure into account, is developed. Kinematic hardening is modeled using a varia

Soft and Hard Mesons in Chiral Perturbation Theory

This thesis deals with Chiral Perturbation Theory (ChPT), an effective field theory for the strong force used to describe meson interactions. The work done can be split in two parts. The first one is on ChPT in its standard formulation. This theory has been very successful so far in describing low energetic processes. However, it is still not entirely clear how much it can be trusted for precision

Simple is Better? - An Experiment on Requirements Prioritisation

The process of selecting the right set of requirements for a product release is highly dependent on how well we succeed in prioritising the requirements candidates. There are different techniques available for requirements prioritisation, some more elaborate than others. In order to compare different techniques, a controlled experiment was conducted with the objective of understanding differences
