Estimation of high-resolution multidimensional spectra from unevenly sampled limited sized data sets plays an important role in a large variety of signal processing applications. In this work, we develop a high-resolution non-parametric estimator for unevenly sampled N-dimensional data based on a recently introduced iterative method, the so-called iterative adaptive approach (IAA). The proposed es

Motor neuron degeneration is a critical phenomenon during spinal cord injuries and some neurodegenerative diseases. However, the mechanisms by which cell death is induced in these neurons are poorly understood. One reason for this, is the lack of model systems in which the survival and death of adult motor neurons can be studied under controlled conditions. This thesis is an attempt to develop suc

Popular Abstract in Swedish Att finna metoder som är snabbare, ger noggrannare resultat och utökar möjligheterna är det övergripande målet för forskningen inom teoretisk kemi. Denna avhandling utgör inget undantag. Sålunda, CI rutiner som möjliggör större beräkningar än tidigare har implementerats i RASSCF modulen i Molcas; nya metoder att lokalisera multipolmomement och polariserbarheter har utveThe method development research in the field of theoretical chemistry is the never ending quest for methods that are faster, gives more accurate results, and expands the possibilities. The work in this thesis is no exception to that statement. Thus a CI routine more suited for calculations on large active spaces was implemented in the RASSCF code of Molcas; a new scheme for localizing multipole mo

Simulation and computer-aided analysis of complex mechanical systems has become a task of increasing importance in computational mechanics. It requires software tools combining modeling support, efficient generation of the equations of motion as well as modern numerical solution and system analysis techniques.

Vehicles in the future are anticipated to have the ability to communicate and exchange useful information in order to avoid collisions. However, for this cooperation to be possible all vehicles will have to be equipped with compatible wireless IEEE 802.11p modules that implement intelligent transport systems operating in the 5 GHz frequency band standard (ITS-G5 or WAVE). During the implementation

The placement of verse 20 in Psalm 72 has long puzzled scholars and has raised a number of questions: Why is תפלה used? Why does it state that the prayers of David are ended? Where does this leave Solomon (v. 1)? Why is it placed after the doxology of vv. 18–19? And why is it found in the middle of the Elohistic Psalter? To solve these problems, a number of suggestions have been presented, none of

Popular Abstract in Swedish Avhandlingen handlar om de personliga följderna av de tidiga konsekvenserna av kronisk ledgångsreumatism, hur det påverkar personernas arbetsliv och hur de hanterar detta. I denna kvalitativa studie har tematiserade intervjuer använts. Tjugotre personer, vilka nyligen diagnostiserats med kronisk ledgångsreumatism, var intervjuade två gånger med två års mellanrum. StudieThis dissertation discusses the personal implications of the early consequences of rheumatoid arthritis, how they effect the person's working life and how they are dealt with. In this qualitative study thematized interviews are used. Twenty-three persons, recently diagnosed with rheumatoid arthritis, were interviewed twice, two years apart. The study is influenced by an interactionist perspective

Popular Abstract in Swedish En ny organisation har identifierats i multinationella företag. Vad utmärker denna? Vilka är skillnaderna mot tidigare? Denna avhandling beskriver och förklarar multinationella företags organisation utifrån en utvidgad nyinstitutionell ekonomisk teori för samordningsmekanismer och samordningsformer. Nya organisatoriska inslag identifieras och analyseras utifrån denna teDuring the 1980s and the 1990s several researchers have described new organisational features and a new organisational form in multinational enterprises, linked to a variety of theoretical approaches. Can the new organisational features be analysed from a consistent theoretical basis, and can, hereby, a new organisational form be distinguished from earlier forms? The purpose of this dissertation i

Popular Abstract in Swedish I början 1990-talet upptäcktes att det var möjligt att syntetisera så kallad mesoporös silika. Upptäckten fick stor uppmärksamhet då materialen har ett flertal intressanta egenskaper som inkluderar ett stort antal porer med väldefinierad diameter, jämn partikelstorlek och möjligheten att påverka dessa och andra egenskaper. I den här avhandlingen har det mesoporösa siliSeveral aspects related to the mesoporous silica material SBA-15 have been studied through the use of a wide range of experimental techniques, including low voltage high-resolution scanning electron microscopy, small angle X-ray scattering and nitrogen sorption. This work contains three parts, which are in many ways overlapping. The first part deals with the formation of SBA-15, it is found that a
