In optically controlled quantum computers it may be favorable to address different qubits using light with different frequencies, since the optical diffraction does not then limit the distance between qubits. Using qubits that are close to each other enables qubit-qubit interactions and gate operations that are strong and fast in comparison to qubit-environment interactions and decoherence rates.

Polygenic effects have more than one cause. They testify to the fact that several causal contributors are sometimes simultaneously involved in causation. The importance of polygenic causation was noticed early on by Mill (1893). It has since been shown to be a problem for causal-law approaches to causation and accounts of causation cast in terms of capacities. However, polygenic causation needs to

As a pre study for future work the output from a regular plane solid 2-dimensional finite element was compared with the output from a solid 2-dimensional axisymmetric finite element. It was done by creating a very simple finite element model for the heat convection problem. The purpose was to compare the results from a heat convection analysis. The model can be used directly for the mass diffusion

Circadian variation in atrial fibrillation (AF) frequency is explored in this paper by employing recent advances in signal processing. Once the AF frequency has been estimated and tracked by a hidden Markov model approach, the resulting trend is analyzed for the purpose of detecting and characterizing the presence of circadian variation. With cosinor analysis, the results show that the shortterm v

Religion can heal, but it can hurt as well. This collection of essays addresses some key issues of religious stereotyping, prejudice, and discrimination, and considers a wide range of important topics which haunt our societies today. When stereotyping becomes the oxygen we inhale, when it is so important to us that we cannot see how we can survive without it - what can and should we do? Twenty-two

Banverket äger och förvaltar ett stort antal tunnlar samtidigt som planering och byggande pågår för ett flertal tunnlar. Syftet med föreliggande arbete är att öka kunskapen och på sikt förbättra och förenkla processen angående personsäkerhet i tunnlar. Rapporten beskriver det inventeringsarbete som utförts med avseende på både befintliga och nya tunnlar med fokus på personsäkerhet...

Om komplementariteter mellan fysisk kapitalbildning och ingenjörsutbildning.

Genomgång av de tre arenor på vilka Bengt Lidforss agerade inom Akademiska Föreningen (AF): en privat (hans bostad i ett av AF:s studentrum), en offentlig (hans verksamhet som debattör och talare vid AF:s publika tillställningar) och en semioffentlig (umgänget inom det s k Tuakotteriet).
