Through practical experiments, edge-wear analysis, and the study of archaeological collections, the dissertation explores the complex relationship between style and function in a specific class of artifacts: the Neolithic axe. The results of the three-part approach described above, when applied for instance to thin-butted axes from the Funnel Beaker Culture, indicated that there was no clear-cut c

In 2006, a prohibition on less favourable treatment of workers related to parental leave was introduced in The Swedish Act on Parental Leave. The prohibition was designed on the basis of the rules on discrimination of pregnant workers and workers on maternity leave in the Equal Treatment directive. The Swedish rules do however separate from the EU rules in one crucial respect. While the European U

Yesterday’s sole hardware product is becoming more and more rare. Today, the original products are increasingly surrounded by value adding services, software or control systems, all bundled together to a “total offer”. Christopher (1998) states that it is the totality of the offer which delivers customer value, and that adding value through differentiation and/or service is a powerful means of ach

This thesis deals with numerical simulations of the turbulent combustion process in Homogeneous Charge Compression Ignition (HCCI) engines. An accurate and computationally efficient Large Eddy Simulation (LES) model was developed and used throughout this thesis to investigate the development of in-cylinder turbulence, temperature stratification, onset of auto-ignition, and development of the react

The aim of this study was to evaluate the effect of a new treatment consisting of stretching, posture training, and auricular acupuncture immediately and at a 3-month followup. This method has not been tested previously. From an original pool of 41 potential subjects, we recruited 24 (12 men, 12 women; ages 18-70 years) into this study and divided them from a waiting list into either a treatment g

This dissertation examines the labor market outcomes of a population of natives and immigrants in Sweden from 1968 and until 2001. Previous research has consistently pointed to the importance of an individual’s country of origin, without being able to fully explain why this is the case. The standard approach is to use the country of origin as a way to measure everything occurring prior to migratio

Transitioning into retirement is an under-researched phenomenon in developing countries. Largely, this is linked to a predominance of contexts where –in particular –the rural population remains outside the coverage of any formal pension system. In 2008, China introduced the New Rural Social Pension (NRSP), a program which by now covers the majority of the Chinese rural elderly. This paper examines

Numerous geometric problems in computer vision in- volve the solution of systems of polynomial equations. This is true for problems with minimal information, but also for finding stationary points for overdetermined problems. The state-of-the-art is based on the use of numerical linear algebra on the large but sparse co- efficient matrix that represents the expanded original equation set. In this
