Analysis of multifunctional traffic environments

The following paper is a compilation of the ongoing Swedish PhD-project “Multifunctional streets in the city - towards a more attractive city for all users and stakeholders”. In focus are arterial streets, i.e. highly multifunctional traffic environments characterized of conflicting functions, with an extensive mix of traffic modes, activities and interests. The aim of the project is to clarify an

Correlated crystal potentials in band structure calculations

The authors give a critical discussion of different current band structure schemes and their relaxation to experiment. They then discuss the connections, exact and approximate, that exist between the electron self-energy and experiment, considering in particular optical absorption and photoemission. Different computationally feasible approximation schemes based on a dynamic generalization of the n

An accurate method for predicting light scattering from soot aggregates with sub-particles of arbitrary shape and structure

Soot particles can be formed in hydrocarbon flames as a result of an inefficient combustion process. The particles are near-spherical, and normally a few tens of nanometers in diameter. At later stages in the soot growth process, they form chain-like sparse aggregates. When applying optical diagnostic methods such as combined scattering and extinction measurements in sooting flames, this aggregati

Sustainable Packaging of Organic Food: Myth or Reality?

Popular Abstract in Swedish Förpackningar finns nästan överallt! Ta en titt nästa gång du äter frukost – redan där på morgonen möter och hanterar du ett flertal olika livsmedelsförpackningar. De finns där även om du kanske inte tänker så mycket på dem, mer än när de är svåröppnade, svåra att hälla ur eller när de rent av läcker. Förpackningar har som jag ser det tre funktioner: de ska kunna skyddaPrevious research has argued that packaging has a great potential to contribute to sustainable development, but how to put this potential into practice is not yet fully explored. The theoretical foundation of the research presented is at the intersection of packaging logistics and sustainable development. This foundation was chosen because it offers established models that are well linked to the h

Självbiografiskt skapande

Licentiatuppsatsen handlar om självbiografiskt skapande och tar utgångspunkt i tre huvudspår. Det första är den egna positionens roll och hur man skulle kunna argumentera för en individuell objektivitet. Det andra behandlar medieringen av jaget och

A Comparison of Two 10 GHz Beam Forming Transmitters, in 90 nm and 130 nm CMOS

A 10 GHz beam forming transmitter was designed in a 90 nm and a 130 nm CMOS process. Two power amplifers with independently controllable phase enable the beam forming. The controllable phase is accomplished by switching in binary weighted transistors fed by quadrature signals, which are generated by a quadrature voltage controlled oscillator followed by a buffer. The designs contain seven differen
