11. Computational problems in evolution : Multiple alignment, genome rearrangements, and tree reconstruction
Sammanfattning : Reconstructing the evolutionary history of a set of species is a fundamental problem in biology. This thesis concerns computational problems that arise in different settings and stages of phylogenetic tree reconstruction, but also in other contexts. LÄS MER
12. Arbetarrörelsen, Folkets Hus och offentligheten i Bromölla 1905-1960
Sammanfattning : The purpose of this dissertation is to analyze the People’s House in Bromölla as an arena for a plebeian public sphere. More specific, the analysis revolves around how the labour movement created a plebeian public sphere, the construction of the very arena and the activities there, including study circles, labour library, theatre plays, film showings, dance evenings and other amusements as parts of adult education among the working class people.

13. Skolans matematik : En kritisk analys av den svenska skolmatematikens förhistoria, uppkomst och utveckling
Sammanfattning : I argue that common beliefs regarding mathematics originate in the practices of elementary mathematics instruction rather than in science. While learning how to solve mathematical problems in school, we come to believe that mathematics has a set of properties in itself, for instance that it is useful in everyday life, even though this is not necessarily so.

14. Optimization of Structures in Contact
Sammanfattning : This dissertation addresses the problem of developing theory, algorithms and computational methodology for optimization of structures in contact. Three particular research problems are studied: (i) developing efficient and reliable optimization algorithms for solving structural optimization problems including contact, (ii) creating more realistic state problems for structures in frictional contact, and (iii) developing computational methodology for shape optimization of structures in frictionless contact.

15. Extreme points of the Vandermonde determinant and phenomenological modelling with power exponential functions
Sammanfattning : This thesis discusses two topics, finding the extreme points of the Vandermonde determinant on various surfaces and phenomenological modelling using power-exponential functions. The relation between these two problems is that they are both related to methods for curve-fitting. LÄS MER
