Popular Abstract in Swedish Genom århundradena har ingenjörskonsten och naturvetenskapen genomsyrats av en önskan att förstå och kontrollera den materia som omger oss. All materia, till exempel träd, byggnader och mobiltelefoner, består av olika slags atomer som är arrangerade i en mängd olika strukturer. Från människans första försök att tillverka redskap genom att manipulera flintstenar och metaThis thesis investigates different methods for treating strongly correlated systems, and discusses their respective strengths and weaknesses. Many of the results presented in this thesis come from comparing the different methods and approximations to exact results. Paper I: We studied the real-time dynamics of a trapped fermion gas, as it expands after removal of a trapping potential. Paper II: We

The university programmes are basically nationally based, developed from the historical needs of specific need of a society. The Bologna process is challenging the educational market mainly at post-graduate level. The exchange of students is still limited to a reduced number of curious and ambitious persons, many with a high interest for cultural exchange – the ‘exotic dimension’. Individual caree

We investigate whether acquiring more education when young has long-term effects on risk-taking behavior in financial markets and whether the effects spill over to spouses and children. There is substantial evidence that more educated people are more likely to invest in the stock market. However, little is known about whether this is a causal effect of education or whether it arises from the corre

Many animals, and all plants and fungi, produce vegetative offspring, i.e. descendant individuals that originate from mitotic, rather than meiotic, cell lineages. Many animals, and all plants and fungi, produce vegetative offspring, i.e. descendant individuals that originate from mitotic, rather than meiotic, cell lineages. The overall purpose of this work is to increase our understanding of the e

This paper proposes a technique for letting end users build pervasive applications by combining services on networked devices. The approach avoids relying on standardized service interfaces which are deemed too limiting, and instead makes use of migratable user interfaces and scripted combinations of services.

Vid LTH ska lärare under kursers genomförande ha kvalitetsdialog med studenterna. I samband med kursslut ska studenterna ges möjligheten till kursvärdering med enkäten CEQ (Course Experience Questionnaire). Enkätdata från CEQ avses utgöra delar av underlaget för kvalitetsarbetet. Svarsfrekvenserna för kursvärderingsenkäterna vid LTH varierar stort, med ett snitt på drygt 50 %. När upplevelser, upp

The paper presents the theory for a design toot to calculate drying of concrete, from green condition to flooring. The degree of hydration, the cement ratio of the concrete, the temperature and the moisture state are taken into account. The moisture calculations are based on the use of Kirchhoff potentials. Calculation examples and comparison with experiments are also given in the paper.

With the growing popularity of audio and video communication services on the Internet, network operators, service providers and application developers are becoming increasingly interested in assuring that their services give the best possible experience to the users. Since real-time audio and video services are very sensitive to packet loss, latency and bandwidth variations, the performance of the

This paper presents views and observations about some current social problems in Poland. The problems introduced are theoretically discussed in reference to Poland’s entry in the European Union. The argumentation in this paper is performed in three stages. The first stage presents a model of Polish society throughout communism towards today’s society, were the weight is put on the Catholic Church’
