Popular Abstract in Swedish Avhandlingen är uppdelad i två delar. Del I analyserar kapacitet för linjära modulationssystem med en bärvåg. Inom dessa system så skickas bitarna som en sekvens av pulser, där varje puls representerar en bit. När pulserna lanseras över kommunikationskanalen, så kommer de utsättas för reflektioner, interferens, och andra störningar. Kapaciteten är en övre gräns på antal
BACKGROUND: Liver resection provides the best chance for cure in colorectal cancer (CRC) liver metastases. A variety of factors that might influence survival and recurrence have been identified. Predictive models can help in risk stratification, to determine multidisciplinary treatment and follow-up for individual patients. AIMS: To systematically review available prognostic models described for o
BACKGROUND AND AIMS: The optimal position for pH electrode placement in the diagnosis of gastroesophageal reflux disease (GERD) is unknown. The aim of this study was to evaluate the discriminatory power of targeted pH recording immediately above the squamocolumnar junction (SCJ) and to compare the results with those obtained by simultaneous recording at the conventional level for pH monitoring. SU
Målet är att undersöka hur en ökad installation av solceller kommer att påverka lågspänningsnätet. Öresundskraft efterfrågade en rapport som undersöker framtida problem i deras nät när solcellssystem installeras i större omfattning. Scenarion där olika procentantal kunder i lågspänningsnätet installerar solceller har analyserats och simulerats. Två olika lågspänningsnät har används, ett område påThe goal of this report is to examine the impacts of integrating Photovoltaic systems in low voltage networks. Öresundskraft requested a report on what problems can arise in the future as more and more people start using PV systems. Scenarios where a certain percentage of an area will install PV systems have been simulated, as well as further analysis of the results from the simulations and calcul
This thesis revolves around rain, more specifically the relationship between urban development and rain. In this part of the world rain is often considered something negative and something that we want to avoid. Architecture has been implemented in order to create structures which protect us from the water falling from the sky. Rain is something we complain about to our friends and colleagues, i
Enligt den amerikanska forskaren Richard Florida är det idag kreativitet och initiativkraft som driver ekonomin och utvecklingen framåt. Det samhälle som lyckas bäst är det som bäst tar vara på befolkningens kreativa potential och som mest framgångsrikt lockar till sig kreativa individer. Genom att analysera vilket samband som finns mellan Skånes kommuners satsningar på kultur & fritid och fas
This thesis gives a contribution to strategy-proof social choice theory, in which one investigates to what extent there exist voting procedures that never can be manipulated in the sense that some voter by misrepresentation of his preferences can change the outcome of the voting and obtain an alternative he prefers to that honest voting would give. When exactly one element should be elected from a
Obtaining DNA sequences is a time-consuming task, which typically requires one or several days for completion. One way of reducing analysis times is to be satisfied with long-range sequence patterns on the order of thousands of base pairs. DNA barcoding is a DNA-characterising technique that works according to this principle. It does so by using fluorescence microscopy to visualise long-range sequ
The best valve substitute for aortic valve replacement (AVR) in terms of hemodynamic performance, durability, incidence of complications, and survival remains the subject of much debate. It has been suggested that valve performance is influenced by the potentially modifiable variable prosthesis-patient mismatch (PPM). PPM has been reported to be detrimental for survival and symptom resolution main
Classification of speed profiles is necessary to allow interpretation of automatic speed measurements in terms of road user behaviour. Aggregation without considering variation in individual profile shapes easily leads to aggregation bias, while classification based on exogenous criteria runs the risk of loosing important information on behavioural (co-) variation. In this paper we test how three
Popular Abstract in Swedish Reglering av celltillväxt och celldöd är mycket viktigt för bibehållandet av balansen mellan antalet olika celler i kroppen. Om regleringen rubbas kan olika sjukdomar uppkomma, som karakteriseras av för mycket celltillväxt eller av för mycket celldöd. Exempel är cancer, där man har för mycket tillväxt, samt många degenerativa sjukdomar som diabetes, Parkinsons och aids,
Due to the increasing interest of producing power from renewable and non-conventional resources, organic Rankine cycles are finding their place in today’s thermal energy mix. The main influencers on the efficiency of an organic Rankine cycle are the working fluid and the expander. Therefore most of the research done up to date turns around the selection of the best performance working media and th
The aims of the thesis are to investigate the estimation power and the normality of standardized residuals for Generalized autoregressive conditional heteroscedasticity models (GARCH). We facilitate the analysis by only dealing with GARCH(1, 1) models. We take use of MATLAB as the statistical programming tool for the simulation of the data and the estimation. We define the meaning of estimation
The task consisted in helping Tetra Pak with the problem that they today have with unexplained deformation of their creasing carriages. Tetra Pak uses different carriages depending on which kind of packaging that is to be manufactured. The carriages are hauled in and pulled in to the production line when another type of packaging is to be manufactured. Basically the carriages look the same, the th
Muntlig bevisning har länge medfört problem i den svenska hovrätten. När ett mål når den andra instansen har kvaliteten på muntlig bevisning blivit sämre, inte minst på grund av att minnesbilder hos förhörspersoner försvagas med tiden. Trots det har utgångspunkten, allt sedan det muntliga och omedelbara förfarandet introducerades genom 1948 års rättegångsbalk (RB), varit att principen om det bästaOral evidence has caused problems in the Swedish courts of appeals for a long time. When a case reaches the higher court, the quality of oral evidence has deteriorated, primarily because the recollections of witnesses and parties have weakened over time. The starting point has, nevertheless, been that the principle of the best evidence requires renewed questioning of witnesses and parties in the c
AIMS AND OBJECTIVES: To describe lesbian, gay and bisexual parents' experiences of nurses' attitudes in child healthcare.BACKGROUND: Lesbian, gay and bisexual people are often reluctant to disclose their gender identity for fear of discrimination. This fear may lead to avoidance of healthcare for themselves or their children and may negatively affect families' health and well-being.DESIGN: A quali
The carbon cycle of the terrestrial biosphere plays a vital role in controlling the global carbon balance and, consequently, climate change. Reliably modeled CO2 fluxes between the terrestrial biosphere and the atmosphere are necessary in projections of policy strategies aiming at constraining carbon emissions and of future climate change. In this study, SMOS (Soil Moisture and Ocean Salinity) L3
Based on molecular dynamics simulations of four globular proteins in dilute aqueous solution, with three different water models, we examine several, essentially geometrical, aspects of the protein-water interface that remain controversial or incompletely understood. First, we compare different hydration shell definitions, based on spatial or topological proximity criteria. We find that the best me
The demands on library services are quickly changing in a continually updating digital age. This increases the importance of a good understanding of the needs and demands of the users. In order to sample and follow the change in user needs library organisations analyse their efforts using a series of different methods. In a recent survey distributed to all 301 European LIBER university libraries,
