The Greenland Ice Sheet (GrIS) is seeing an accelerated rate of ice melt, which increasingly contributes to global sea-level rise. Studies have reported a growing mass imbalance coinciding with a widespread retreat of the island’s glacial termini. The associated discharge of ice is driven by submarine melting and ice breaking off glacial fronts, a process known as calving. The rate at which calvin
Adders are fundamental building blocks in Application-Specific Integrated Circuits (ASICs) and play a central role in the arithmetic datapaths of modern digital signal processing systems. Operations such as finite impulse response (FIR) filtering, beamforming, and signal combining rely on evaluating weighted sums of multiple inputs. These computations can be expressed as linear combinations and ar
This thesis presents the design and schematic-level simulation of a highly linear mixer-first receiver front-end implemented in CMOS, targeting improved robustness against strong input signals. The proposed architecture employs a current-mode passive mixer directly loaded by a low-impedance transimpedance amplifier (TIA) in order to minimize the voltage swing at the mixer output and thereby enhanc
Heavy-duty trucks, especially those used in urban areas, are responsible for a disproportionally large share of the external costs of the transportation sector. Policy instruments that target these trucks could thus be efficient measures to reduce negative impact from the traffic sector. This paper presents how heavy-duty trucks operated in Sweden’s two largest cities, Gothenburg and Stockholm, in
Distillation is the primary separation technique in the petrochemical industries, but it operates with extremely low thermodynamic efficiency. It represents the largest share of industrial energy consumption, making its decarbonization a global priority. While advanced process technologies, such as Mechanical Vapor Recompression (MVR) and the Heat-Integrated Distillation Column (HIDiC), offer a pa
Direct-to-Device (D2D) communication in Non-Terrestrial Networks (NTNs) enables smartphones to connect directly to satellites, extending wireless coverage beyond terrestrial networks. This thesis presents the design of a smartphone antenna optimized for NTN operation, followed by a link budget analysis and Electromagnetic Field (EMF) exposure assessment. The proposed solution is a dual-band circu
Spiral galaxies host elongated filamentary structures of dense gas and dust, known as feathers, which branch off the main spiral arms into the interarm regions and are associated with star formation. The physical mechanisms governing their formation remain debated, with magnetic fields proposed as one of the contributing factors. This thesis investigates the role of magnetic fields in feather form
Objective: To determine the incidence and clinical significance of neutralizing antibody (NAb) formation in patients with relapsing multiple sclerosis ( MS) who participated in the European Interferon Beta-1a IM Dose-Comparison Study. Methods. Patients were randomized to treatment with interferon beta-1a (IFN beta-1a) 30 mu g or 60 mu g IM once weekly for up to 4 years. Serum samples obtained at b
When measuring the production rates of heat and smoke of upholstered furniture the ignition source must not influence the test results. In this paper variations in the strength, application time and geometry of the ignition burner used in the furniture calorimeter are studied. Results from replicate furniture calorimeter chair test show that the burning behaviour is almost independent of the burne
Mortgage loan providers estimate the credit risks it caries when approving a mortgage loan to their clients. Further, defaulting a mortgage loan is a risk that has been calculated through decades using statistical models. By using entries at the time of a mortgage application, the goal of the thesis is to com- pare the accuracy between logistic regression and Support Vector Machine in predicting
This master thesis work concerns the effect of high-alumina additives on the selfdesication of concrete. The purpose of the work was to examine the possibilities to optimize the binder-content of concrete with regards to self-desiccation. Two highalumina additives have been examined. In the experiments 10% of the binder mass has been replaced with one of these additives. Commercially available ceme

Sedan hösten 2006 har lagstiftningsprocessen fått ett nytt inslag. Ett oreglerat och nästan okänt inslag, men ack så viktigt. När de fyra borgerliga partierna under åren 2004-2006 förberedde ett eventuellt regeringsskifte efter valet 2006 så var den s.k. Äntringsstyrkans arbete mycket viktigt. Ett av deras viktigaste förslag var att en mekanism för all samordning mellan de fyra partierna skulle inSince fall 2006, the legislative process has a new element. An unregulated and almost unknown element, however very important. When the four center right wing parties during the years 2004-2006 were preparing a possible change of government after the 2006 election, the work of the so-called “Äntringsstyrkan” was very important. One of their main proposals was that a mechanism for all coordination
The modern human being is exposed to different kinds of light during a normal day, both natural light and adjusted lighting. The idea that light affects us is uncontested, and so affecting the light in turn becomes a question of well-being. It is often thought that abundant and strong lighting is good lighting, but this is far from always accurate. Moreover, the light from a regular lightbulb is i
After the failure to respond adequately to the changing patterns of conflict and violence after the end of the Cold War, human security was popularized in the 1990s as an alternative concept to security more suitable to face threats to individual security. Ever since, the question about what human security should entail has seen much discussion. This paper examines the different discourses which i
A method is described for measurement of freely dissolved copper concentrations in natural water samples using supported liquid membrane (SLM) extraction under equilibrium conditions, a technique denoted "equilibrium sampling through membranes" (ESTM). For this purpose, 1,10-dibenzyl-1,10-diaza-18-crown-6 as neutral carrier and oleic acid were used in the membrane phase. The main variables optimis
Background: The aim of the present study was to evaluate the future cumulative risk of prostate cancer in relation to levels of prostate-specific antigen (PSA) in blood and to determine whether this information could be used to individualize the PSA testing interval. Methods: The study included 5855 of 9972 men (aged 50-66 years) who accepted an invitation to participate in a prospective, randomiz
Duodenal levodopa infusion represents an effective strategy to manage motor and non-motor complications in patients with advanced Parkinson's disease (PD). However, most published clinical series regard small numbers of patients and do not exceed 1 year follow-up. In this multi-national observational cohort study conducted in seven specialised PD clinics and university hospitals we assessed long-t
Denna uppsats syftar till att undersöka vilka effekter ett införande av fotboja som ungdomspåföljd skulle innebära för de unga som i så fall skulle komma i fråga för påföljden. Utgångspunkt tas i det förslag på införande av fotboja för unga som återfinns i SOU 2012:34 Nya påföljder, där påföljden kallas för ungdomsövervakning. Inledningsvis tecknas en översiktlig bild av det rättspolitiska dagsläThe aim of this thesis is to examine the potential effects on youths of an introduction of electronic tagging into the Swedish penal system for juveniles. The proposition of such electronic tagging, presented in SOU 2012:34 Nya påföljder (“New sanctions”) by the name ungdomsövervakning (“youth monitoring”), acts as a starting point for the investigation of the expected effects on youths. First,
Gällande entreprenadarbeten torde det vara vanligt förekommande att beställaren påtalar fel som denne vill att entreprenören ska avhjälpa. För att en part ska kunna aktualisera en påföljd vid påstått kontraktsbrott krävs enligt branschavtalet AB 04, precis som enligt allmän förmögenhetsrätt i övrigt, att en reklamation företas. Syftet med uppsatsen är därför att undersöka hur beställarens påkallanWhen it comes to contract work in the construction sector it is common that the client points out faults that he wants the contractor to rectify. For a party to be able to enforce a sanction in the event of an alleged breach of contract, the branch regulation AB 04 prescribes, just as according to general property law, that a complaint is made. The purpose of the thesis is therefore to investigate
