Popular Abstract in Swedish Större delen av den kunskap vi har om Universum får vi genom att undersöka det ljus som olika kosmiska objekt sänder ut. Det synliga ljuset från en stjärna består av kontinuerlig strålning (Planckstrålning) vars färg ger ett mått på temperaturen av stjärnans yta på samma sätt som färgen hos upphettade metallföremål. Vid en närmare undersökning av stjärnans spektrum kan The new generation of high resolution astronomical instruments such as the Hubble Space Telescope (HST) or the Very Large Telescope (VLT) has renewed the demand for accurate atomic parameters like wavelengths, oscillator strengths and line profiles accompanied by reliable uncertainty estimates. Fourier transform spectroscopy has proven to be a powerful tool when measuring these parameters. In this

Abstract This report discusses ways in which new technology could be harnessed to create an intelligent Virtual Personal Assistant (VPA) with a focus on user-based information. It will look at examples of intelligent programs with natural language processing that are currently available, with different categories of support, and examine the potential usefulness of one specific piece of software as

In this paper we consider fundamental limitations for DOA estimation with arbitrary lossless antennas or antenna arrays inserted inside a sphere. Spherical vector modes and their associated equivalent circuits and Q factor approximations are employed as a general framework for the analysis. The classical broadband matching theory by Fano is extended to a general multiport S-parameter model of the

Nematophagous fungi are parasites of nematodes, thus they have been considered and tested for biological control of parasitic nematodes, but so far with limited success. Due to the fact that the nematode cuticle is composed of proteins it is likely that fungal extracellular proteases are involved in the infection of nematodes. I have isolated a gene (designated PII) encoding an extracellular cutic

Popular Abstract in Swedish Värmestrålning är högst relevant i förbränningsmiljöer. I dessa miljöer är förbränningsgaser och partiklar den huvudsakliga källan till värmestrålning. Förbränningsmiljön är komplex att beskriva. Analys av turbulenta flöden, kemiska reaktioner och transport av energi måste göras för att fullständigt beskriva miljön. Att kunna beskriva dessa fenomen är en viktig del i föThermal radiation is an important physical phenomenon in combustion environments. For the understanding of existing- and the design of new combustion environments computational modelling is a useful tool as it can describe the different transport phenomena. This thesis has focused on studying thermal radiative property models of the participating media, gases and particles. Two specific combustion

The paper deals with the problem of finding suboptimal routing paths in multi-domain Internet environment. The proposed solution can be used in traffic enginering with MPLS.

Design starts with a cognitive model and ends with a solution worked out in a way that fits into the human context of meaning which is socially decided. The bridge between the cognitive model and the final system, or thing, is a proper description that has to be possible to socially communicate. The necessary description part leads to the understanding that design, like sciences, is a kind of lear

In the software industry, there is a strong shift from traditional phase-based development towards agile methods and practices. This paper reports on a case study aimed at investigating if, and how, agile Requirements Engineering (RE) can remedy the challenges of traditional RE, and what new challenges agile RE may pose. The results from an initial case study with 9 practitioners from a large soft

Nanosized soot particles are a serious health hazard in urban air. Upon inhalation they can penetrate deep into the lungs and their fat solubility makes possible their accumulation in other organs such as the brain. For this reason legislation has continuously reduced the allowable emission levels and raised requirements for reporting the status of the exhaust system (OBD, on board diagnostics) in
